    IMPORTANCE Many adolescents and young adults use alternative tobacco products, such as water pipes and snus, instead of cigarettes. OBJECTIVE To assess whether prior water pipe tobacco smoking and snus use among never smokers are risk factors for subsequent cigarette smoking. DESIGN, SETTING, AND PARTICIPANTS We conducted a 2-wave national longitudinal study in the United States among 2541 individuals aged 15 to 23 years old. At baseline (October 25, 2010, through June 11, 2011), we ascertained whether respondents had smoked cigarettes, smoked water pipe tobacco, or used snus. At the 2-year follow-up (October 27, 2012, through March 31, 2013), we determined whether baseline non–cigarette smokers had subsequently tried cigarette smoking, were current (past 30 days) cigarette smokers, or were high-intensity cigarette smokers. We fit multivariable logistic regression models among baseline non–cigarette smokers to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with subsequent cigarette smoking initiation and current cigarette smoking, accounting for established sociodemographic and behavioral risk factors. We fit similarly specified multivariable ordinal logistic regression models to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with high-intensity cigarette smoking at follow-up. EXPOSURES Water pipe tobacco smoking and the use of snus at baseline. MAIN OUTCOMES AND MEASURES Among baseline non–cigarette smokers, cigarette smoking initiation, current (past 30 days) cigarette smoking at follow-up, and the intensity of cigarette smoking at follow-up. RESULTS Among 1596 respondents, 1048 had never smoked cigarettes at baseline, of whom 71 had smoked water pipe tobacco and 20 had used snus at baseline. At follow-up, accounting for behavioral and sociodemographic risk factors, baseline water pipe tobacco smoking and snus use were independently associated with cigarette smoking initiation (adjusted odds ratios: 2.56; 95% CI, 1.46-4.47 and 3.73; 95% CI, 1.43-9.76, respectively), current cigarette smoking (adjusted odds ratios: 2.48; 95% CI, 1.01-6.06 and 6.19; 95% CI, 1.86-20.56, respectively), and higher intensity of cigarette smoking (adjusted proportional odds ratios: 2.55; 95% CI, 1.48-4.38 and 4.45; 95% CI, 1.75-11.27, respectively). CONCLUSIONS AND RELEVANCE Water pipe tobacco smoking and the use of snus independently predicted the onset of cigarette smoking and current cigarette smoking at follow-up. Comprehensive Food and Drug Administration regulation of these tobacco products may limit their appeal to youth and curb the onset of cigarette smoking. PMID:25485959

    OBJECTIVE: Water-pipe tobacco smoking is becoming increasingly more common among young people. The objective of this study was to estimate the prevalence of the use of water pipes and other forms of tobacco use, including cigarette smoking, among medical students, as well as to examine the attitudes, beliefs, and knowledge of those students regarding this issue. METHODS: We administered a questionnaire to students enrolled in the University of So Paulo School of Medicine, in So Paulo, Brazil. The respondents were evaluated in their third and sixth years of medical school, between 2008 and 2013. Comparisons were drawn between the two years. RESULTS: We evaluated 586 completed questionnaires. Overall, the prevalence of current cigarette smokers was low, with a decline among males (9.78% vs. 5.26%) and an increase among females (1.43% vs. 2.65%) in the 3rd and 6th year, respectively. All respondents believed that health professionals should advise patients to quit smoking. However, few of the medical students who smoked received physician advice to quit. Experimentation with other forms of tobacco use was more common among males (p<0.0001). Despite their knowledge of its harmful effects, students experimented with water-pipe tobacco smoking in high proportions (47.32% and 46.75% of the third- and sixth-year students, respectively). CONCLUSIONS: The prevalence of experimentation with water-pipe tobacco smoking and other forms of tobacco use is high among aspiring physicians. Our findings highlight the need for better preventive education programs at medical schools, not only to protect the health of aspiring physicians but also to help them meet the challenge posed by this new epidemic.

    Water pipe smoking is a recently growing addiction worldwide. It has become popular in Africa and the Western World and enfaces a renaissance in Middle East and Asia. The smoking technique leads to a different exposure to potential hazardous compounds compared to cigarette or classical pipe smoking. The common assumption that water pipe smoking is less dangerous to health is not substantiated by scientific data. Non-tobacco-based preparations reduce the exposure to nicotine but may contain equal or even higher concentrations of other toxic compounds. The medical literature on adverse effect of water pipe smoking on skin and oral mucosa is reviewed but future research is a demand. PMID:25677592

    Environmental tobacco smoke (ETS) is the material released into the environment as tobacco products are smoked. Cigarettes, pipes, and cigars all produce ETS but the term has become all but synonymous with indoor air contamination by cigarette smoking. This is because cigarettes are by far the most commonly consumed tobacco product and because the principal human exposure occurs indoors. Exposure to ETS is variously termed as passive smoking, involuntary smoking, and as exposure to second-hand smoke. Considerable progress has been made toward a better understanding of ETS exposure. Strengths and limitations of various measures of exposure are better understood and much data has been generated on the quantities of many ETS-constituents in many indoor environments. The properties of ETS, methods for its measurement in indoor air, and many results of field studies have recently been reviewed by the author. The recent EPA report includes a major treatment of exposure estimation including air concentrations, questionnaires, and biomarkers. This paper discusses approaches to exposure assessment and summarizes data on indoor air concentrations of ETS-constituents.

    Environmental tobacco smoke (ETS) is the material in indoor air which results from tobacco smoking. Early work on the chemistry of ETS and on estimates of the resulting human exposure relied heavily on studies of sidestream smoke, on the characterization of highly contaminated environments, and on the use of contained experimental atmospheres. It had also been common practice to equate ETS with mainstream smoke for purposes of risk assessments. More recent work has identified potentially important differences between the properties of ETS and those of mainstream smoke. Recent work has also included major surveys of commonly encountered smoking and nonsmoking environments for their indoor air concentrations of, particularly, nicotine, carbon monoxide, and/or respirable suspended particulate matter (RSP). Studies have also now been reported which address the general composition of the particulate and vapor phases of ETS and which measure concentrations of trace and miscellaneous constituents of tobacco smoke in indoor air. The data demonstrate that tobacco smoking clearly contributes to indoor air contamination but that the contribution is often less than was previously assumed for the more-commonly encountered environments. The data also identify difficulties in the use of nicotine, carbon monoxide, and RSP as surrogate measures of ETS as a whole. This paper summarizes recent observation concerning the measurement and concentrations of ETS constituents in indoor air.

  10. Use & Misuse of Water-filtered Tobacco Smoking Pipes in the World. Consequences for Public Health, Research & Research Ethics

    Chaouachi, Kamal

    Background: The traditional definition of an epidemic has been revisited by antismoking researchers. After 400 years, Doctors would have realized that one aspect of an ancient cultural daily practice of Asian and African societies was in fact a global epidemic. This needed further investigation particularly if one keeps in his mind the health aspects surrounding barbecues. Method: Here, up-to-date biomedical results are dialectically confronted with anthropological findings, hence in real life, in order to highlight the extent of the global confusion: from the new definition of an epidemic and prevalence to the myth of nicotine addiction and other themes in relation to water filtered tobacco smoking pipes (WFTSPs). Results: We found that over the last decade, many publications, -particularly reviews, meta-analyses and systematic reviews- on (WFTSPs), have actually contributed to fuelling the greatest mix-up ever witnessed in biomedical research. One main reason for such a situation has been the absolute lack of critical analysis of the available literature and the uncritical use of citations (one seriously flawed review has been cited up to 200 times). Another main reason has been to take as granted a biased smoking robot designed at the US American of Beirut whose measured yields of toxic chemicals may differ dozens of times from others' based on the same protocol. We also found that, for more than one decade, two other main methodological problems are: 1) the long-lived unwillingness to distinguish between use and misuse; 2) the consistent unethical rejection of biomedical negative results which, interestingly, are quantitatively and qualitatively much more instructive than the positive ones. Conclusion: the great majority of WFTSP toxicity studies have actually measured, voluntarily or not, their misuse aspects, not the use in itself. This is in contradiction with both the harm reduction and public health doctrines. The publication of negative results should be encouraged instead of being stifled. PMID:25861403

    In order to estimate the exposure of passive and active smokers to tobacco smoke one can use the questionnaire method or laboratory examination of chemical compounds being widely accepted exposure biomarkers. Substances that make such biomarkers include some of the tobacco smoke components and its metabolites formed in the body. The study discusses two groups of biomarkers. First, includes substances that serve as exposure markers of carcinogenous properties (metabolites of polycyclic aromatic hydrocarbons, N-nitrosamines, trans,transmuconic acid, S-phenylmercapturic acid). Second group includes substances which role is limited to the evaluation of exposure to tobacco smoke (nicotine, cotinine, anatabine, anabasine, trans-3'-hydroxycotinine, thiocyanate, carboxyhemoglobin, carbon monoxide). Sensitivity and specificity of biomakers used were evaluated, their concentration ranges in physiological fluids in non-smokers, passive-, and active smokers. The simplicity of the examination method was evaluated. Articles published during last two decades indicate that the substance that have all features that make it the most appropriate biomarker is cotinine. It can be assessed in plasma and in urine of smokers and persons exposed to environmental tobacco smoke. PMID:16521990

    Tobacco smoking remains the most established cause of lung carcinogenesis and other disease processes. Over the last 50 years, tobacco refinement and the introduction of filters have brought a change in histology, and now adenocarcinoma has become the most prevalent subtype. Over the last decade, smoking also has emerged as a strong prognostic and predictive patient characteristic along with other variables. This article briefly reviews scientific facts about tobacco, and the process and molecular pathways involved in lung carcinogenesis in smokers and never-smokers. The evidence from randomised trials about tobacco smokings impact on lung cancer outcomes is also reviewed. PMID:23984018

  16. Tobacco smoking and vertical periodontal bone loss.

    PubMed

    Baljoon, Mostafa

    2005-01-01

    Cigarette smoking is associated with increased prevalence and severity of destructive periodontal disease in terms of periodontal pocketing, periodontal bone loss, and tooth loss. The smoking destructive effect on periodontal bone may be of even "horizontal" and vertical "angular" pattern. The vertical bone loss or the "vertical defect" is a sign of progressive periodontal breakdown that involves the periodontal bone. Water pipe smoking has a sharp rise by the popularity in the recent years by men and women in Middle East countries. The general objective of this thesis was to investigate the relationship between tobacco smoking and vertical periodontal bone loss cross-sectionally and longitudinally. This thesis is based on two study populations, Swedish musicians and a Saudi Arabian population. All participants had a full set of intra-oral radiographs including 16 periapical and 4 bitewing projections that were assessed with regard to presence or absence of vertical defects. In Study I, the number of defects per person increased with age. Vertical defects were more common in the posterior as compared to the anterior region of the dentition and the distribution of defects within the maxilla as well as the mandible typically revealed a right-left hand side symmetry. Cigarette smoking was significantly associated with the prevalence and severity of vertical bone defects (Studies II and III). The relative risk associated with cigarette smoking was 2 to 3-fold increased. The impact of water pipe smoking was of the same magnitude as that of cigarette smoking and the relative risk associated with water pipe smoking was 6-fold increased compared to non-smoking. In addition, the risk of vertical defects increased with increased exposure in cigarette smokers as well as water pipe smokers (Study III). In Study IV, the proportion of vertical defects increased over a 10-year period and the increase over time was significantly associated with smoking. Moreover, the 10-year vertical bone loss was significantly greater in heavy exposure smokers than in light exposure smokers suggesting an exposure-response effect of smoking. Compared to non-smokers the 10-year relative risk was 2.4-fold increased in light exposure smokers and 5.8-fold increased in heavy exposure smokers. In conclusion, the present observations indicate that there is a significant relationship between tobacco smoking and vertical periodontal bone loss. Tobacco smoking should be considered a risk factor for periodontal vertical bone loss. PMID:15973969

  17. Cadmium concentrations in tobacco and tobacco smoke

    1983-02-01

    The amount of cadmium in tobacco depends on the variety and origin of the plant as well as on the analytical method used to determine cadmium. In the literature, cadmium concentrations in tobacco of between 0.5 and 5 ppm are reported. Modern German cigarette tobacco contains about 0.5-1.5 micrograms cadmium/cigarette. Of importance for the smoker is the amount of the metal in the mainstream smoke. The cadmium level in the mainstream smoke of modern cigarettes is reduced by means of filters and other construction features. The average Cd value of German filter cigarettes is less than 0.1 microgram/cigarette in mainstream smoke. An average daily intake of about 1 microgram cadmium by smoking 20 cigarettes can be calculated on the basis of an experimentally proved pulmonary retention rate of 50%. Pulmonary resorption rates relevant to uptake rates of cadmium by smoking are discussed. It can be assumed that cadmium uptake by smoking modern cigarettes has been reduced because of modifications in tobacco processing and cigarette construction in the last few decades.

    Narghile (water pipe, hookah, shisha, goza, hubble bubble, argeela) is a traditional method of tobacco use. In recent years, its use has increased worldwide, especially among young people. Narghile smoking, compared to cigarette smoking, can result in more smoke exposure and greater levels of carbon monoxide (CO). We present an acutely confused adolescent patient who had CO poisoning after narghile tobacco smoking. She presented with syncope and a carboxyhemoglobin level of 24% and was treated with hyperbaric oxygen. Five additional cases of CO poisoning after narghile smoking were identified during a literature search, with carboxyhemoglobin levels of 20 to 30%. Each patient was treated with oxygen supplementation and did well clinically. In light of the increasing popularity of narghile smoking, young patients presenting with unexplained confusion or nonspecific neurologic symptoms should be asked specifically about this exposure, followed by carboxyhemoglobin measurement.

    2010-01-01

    Background To date, Lebanon has failed to enact comprehensive clean indoor air laws despite ratification of the Framework Convention on Tobacco Control (FCTC), which calls for the protection of non-smokers from exposure to secondhand tobacco smoke (SHS). Complicating the problem of SHS exposure in Lebanon is the widespread use of the tobacco water-pipe. While most research on SHS has involved cigarette smoking as a source of emissions, other sources, including tobacco water-pipes, may be an important contributor. Methods PM2.5 concentrations (μg/m3) were measured in a sample of 28 public venues located in six major Lebanese cities. Active smoker density (number of smokers/100 m3) was calculated for both water-pipe and cigarette smokers. Venues were then categorised as having higher density of water-pipe smokers or higher density of cigarette smokers, and resultant emission levels were compared between the two groups. Results Cigarette and water-pipe smoking was observed in 14 venues, while cigarette smoking only and water-pipe smoking only were found in 12 venues and one venue, respectively. Among all smoking-permitted venues, the mean PM2.5 concentration was 342 μg/m3. Venues with a higher density of water-pipe smokers (n =14) showed a similar median PM2.5 concentration (349 μg/m3) compared with venues with a higher density of cigarette smokers (n =13; 241 μg/m3; p=0.159). The mean PM2.5 concentration in the single venue with a voluntary smoke-free policy was 6 μg/m3. Conclusions Despite ratification of the FCTC in 2005, both cigarette and water-pipe smoking are commonly practised in enclosed public places throughout Lebanon, leading to unsafe levels of indoor particulate pollution. Smoke-free policies are needed in Lebanon to protect the public's health, and should apply to all forms of tobacco smoking. PMID:20378588

    In order to try to predict effects of environmental tobacco smoke, neurobehavioral effects of mainstream smoke were reviewed and, in conjunction with what is known about body uptake of components of environmental tobacco smoke, conjectures were made about the probable effect of environmental tobacco smoke. Effects of mainstream smoke differ in smokers and nonsmokers. Mainstream smoke has a beneficial effect on vigilance in habitual smokers. The effect in nonsmokers is less clear and may be disruptive. In both smokers and nonsmokers mainstream smoke produces increased tremor and reduced fine motor skills. The neurobehaviorally active substances in mainstream smoke appear to be nicotine and carbon monoxide. It appears that COHb is the more important consequence of environmental tobacco smoke for neurobehavioral effects, since nicotine levels in nonsmokers only reach a small fraction of those in smokers.

  4. Comparison of Cigarette and Water-Pipe Smoking By Arab and Non–Arab-American Youth

    Background Water-pipe smoking is a rapidly growing form of tobacco use worldwide. Building on an earlier report of experimentation with cigarette and water-pipe smoking in a U.S. community sample of Arab-American youth aged 14–18 years, this article examines water-pipe smoking in more detail (e.g., smoking history, belief in harmfulness compared to cigarettes, family members in home who smoke water pipes) and compares the water-pipe–smoking behaviors of Arab-American youth with non–Arab-American youth in the same community. Methods A convenience sample of 1872 Arab-American and non–Arab-American high school students from the Midwest completed a 24-item tobacco survey. Data were collected in 2004–2005 and analyzed in 2007–2008. Results Arab-American youth reported lower percentages of ever cigarette smoking (20% vs 39%); current cigarette smoking (7% vs 22%); and regular cigarette smoking (3% vs 15%) than non–Arab-American youth. In contrast, Arab-American youth reported significantly higher percentages of ever water-pipe smoking (38% vs 21%) and current water-pipe smoking (17% vs 11%) than non–Arab-American youth. Seventy-seven percent perceived water-pipe smoking to be as harmful as or more harmful than cigarette smoking. Logistic regression showed that youth were 11.0 times more likely to be currently smoking cigarettes if they currently smoked water pipes. Youth were also 11.0 times more likely to be current water-pipe smokers if they currently smoked cigarettes. If one or more family members smoked water pipes in the home, youth were 6.3 times more likely to be current water-pipe smokers. The effects of ethnicity were reduced as a result of the explanatory value of family smoking. Conclusions Further research is needed to determine the percentages, patterns, and health risks of water-pipe smoking and its relationship to cigarette smoking among all youth. Additionally, youth tobacco prevention/cessation programs need to focus attention on water-pipe smoking in order to further dispel the myth that water-pipe smoking is a safe alternative to cigarette smoking.

    1988-01-01

    Using a smoking machine, reference cigarettes, a commercial brand of nonfilter 85-millimeter cigarettes, a medium-priced cigar, and a popular brand of pipe tobacco, both wet-ashing and dry-ashing procedures were carried out to determine the cadmium content to which smokers were being exposed. Cigarettes varied from 1.31 to 1.28 micrograms (microg) of cadmium per cigarette, which corresponded to 1.17 to 1.62 microg per gram (g) of cigarette. For cigar tobacco a total of 1.86 microg/g was found and in pipe tobacco the content was 0.93 microg/g. Only 6 to 7% of the cadmium in the smoked portion of the cigarette appeared in the tar, while the unsmoked butts were enriched with 10 to 27% of the cadmium of the smoked portions. The authors suggest that the remaining cadmium, 50 to 55%, is lost in the sidestream during smoking and between puffs. This indicated that not only is the one smoking at risk from cadmium exposure, but so are the others present in the vicinity.

    This article provides information on the growing threat of water pipe smoking (hookah) around the world and in the United States. Historically an activity of Middle Eastern older adults, the most recent growth in water pipe smoking (WPS) has been among adolescents and young adults. Associated with its use is a growing list of health problems. To date no interventions have been specifically designed for this form of tobacco use and they are sorely needed. Nurses must continue to teach No Tobacco Use in any form and that means no water pipe smoking must be part of every health message. PMID:22289404

    2013-01-01

    Background: This study assesses self-reported tobacco use prevalence (cigarette, water-pipe, and medwakh) among applicants to Abu Dhabi's Premarital Screening program during 2011. Methods: Premarital Screening data reported to the Health Authority – Abu Dhabi from April to December 2011 were utilized to estimate tobacco use prevalence among applicants. Smoking prevalence was examined by nationality, age group and gender. Results: Overall, 24.7% of Premarital Screening Program applicants were current smokers; 11.5% smoked cigarettes, 5.9% smoked medwakh (hand-held pipe), 4.8% smoked water-pipe and 2.5% smoked a combination (more than one type). Men (19.2%) were more likely than women (3.5%) to be current cigarette smokers. Women were much less likely to smoke medwakh (0.1%) than men (11.5%), with male UAE Nationals having the highest medwakh smoking prevalence (16.1%). The overall prevalence of water-pipe smoking was 6.8% among men and 2.8% for women with the highest water-pipe smoking prevalence (10.2%) among Arab expatriate men. Conclusions: Variations in tobacco use prevalence among Premarital Screening Program applicants reflect preferences for different modes of tobacco consumption by nationality, age group and gender. Enforcement of tobacco control laws, including implementation of clean indoor air laws and tobacco tax increases, and targeted health education programs are required to reduce tobacco consumption and concomitant tobacco-related morbidity and mortality.

    Passive exposure to tobacco smoke significantly contributes to morbidity and mortality in children. Children, in particular, seem to be the most susceptible population to the harmful effects of environmental tobacco smoke (ETS). Paternal smoking inside the home leads to significant maternal and fetal exposure to ETS and may subsequently affect fetal health. ETS has been associated with adverse effects on pediatric health, including preterm birth, intrauterine growth retardation, perinatal mortality, respiratory illness, neurobehavioral problems, and decreased performance in school. A valid estimation of the risks associated with tobacco exposure depends on accurate measurement. Nicotine and its major metabolite, cotinine, are commonly used as smoking biomarkers, and their levels can be determined in various biological specimens such as blood, saliva, and urine. Recently, hair analysis was found to be a convenient, noninvasive technique for detecting the presence of nicotine exposure. Because nicotine/cotinine accumulates in hair during hair growth, it is a unique measure of long-term, cumulative exposure to tobacco smoke. Although smoking ban policies result in considerable reductions in ETS exposure, children are still exposed significantly to tobacco smoke not only in their homes but also in schools, restaurants, child-care settings, cars, buses, and other public places. Therefore, more effective strategies and public policies to protect preschool children from ETS should be consolidated. PMID:22375147

    The objective of this study was to determine the impact of cigarette smoking in hyperthyroidism patients. The study group included patients with Graves-Basedow disease (GB): n = 317 (32.9%), patients with Graves' ophthalmopathy (GO): n = 108 (11.2%), patients with toxic nodular goiter (TNG) n = 511 (53%) and 28 (2.9%) patients with toxic adenoma (TA). Evaluation of tabacco smoking and exposure to environmental tobacco smoke (ETS) was performed on the base of questionnaire acording to Fagerström test. The comparison of GO and GB indicate increased tabacco smoking in GO (OR = 0.36; 95%CI: 0.22-0.59). The frequencies of tacacco smoking displayed significantly increased in GB and TNG patients (OR=0.39; 95%CI: 0.28-0.56). Further analys of patients with GO and TA presented statistcal significance in group of smoking and non-smoking (OR=0.26; 95%CI: 0,073-0,95). In other cases we didn't found a significant influence of tobacco smoking on thyroid disease. The effect of smoking was more pronounced in Graves' patients (particulary in the patients with GO) than in other thyroid patients. Smoking among patients with thyroid disease (GO and GB disease) is associated with developing of anxiety and fright, depression and problems with social relations sphere. PMID:16521936

  12. The relationship between tobacco smoke & bronchial asthma.

    2004-11-01

    Bronchial asthma is a common disease and an important cause of morbidity among both children and adults. Tobacco smoking, both active and passive i.e., exposure to environmental tobacco smoke (ETS) has got important effects on asthma. Smoking by adults causes bronchial irritation and precipitates acute episodes. It also increases bronchial responsiveness and causes airway sensitization to several occupational allergens. Smoking may also increase the disease severity. Continued smoking by adult asthmatics is the likely cause of irreversibility of airway obstruction and development of chronic obstructive pulmonary disease. ETS exposure affects asthma in a similar fashion. Parental smoking is commonly associated with increased asthma symptoms, respiratory infections, acute episodes and frequent hospitalization of children. Bronchial responsiveness and airway sensitization may also increase. Childhood exposure to smoking is also considered as a risk factor for the development of asthma. Similarly, in utero exposure to maternal smoking may be independently responsible for early onset asthma. ETS exposure in adult asthmatics from smoking by spouses, siblings or colleagues is equally troublesome. There is increased morbidity and poorer asthma control. Asthmatic symptoms sharply decline after the ETS exposure is reduced. PMID:15591628

    Traditionally, nicotine from second hand smoke (SHS), active or passive, has been considered the most prevalent substance of abuse used during pregnancy in industrialized countries. Exposure to environmental tobacco smoke (ETS) is associated with a variety of health effects, including lung cancer and cardiovascular diseases. Tobacco is also a major burden to people who do not smoke. As developing individuals, newborns and children are particularly vulnerable to the negative effects of SHS. In particular, prenatal ETS has adverse consequences during the entire childhood causing an increased risk of abortion, low birth weight, prematurity and/or nicotine withdrawal syndrome. Over the last years, a decreasing trend in smoking habits during pregnancy has occurred, along with the implementation of laws requiring smoke free public and working places. The decrease in the incidence of prenatal tobacco exposure has usually been assessed using maternal questionnaires. In order to diminish bias in self-reporting, objective biomarkers have been developed to evaluate this exposure. The measurement of nicotine and its main metabolite, cotinine, in non-conventional matrices such as cord blood, breast milk, hair or meconium can be used as a non-invasive measurement of prenatal SMS in newborns. The aim of this review is to highlight the prevalence of ETS (prenatal and postnatal) using biomarkers in non-conventional matrices before and after the implementation of smoke free policies and health effects related to this exposure during foetal and/or postnatal life.

    Over the past few decades, "Big Tobacco" has spread its tentacles across the developing world with devastating results. The global incidence of smoking has increased exponentially in Africa, Asia and South America and it is leading to an equally rapid increase in the incidence of smoking-induced morbidity and mortality on these continents. The World Health Organization (WHO) has tried to respond to this crisis by devising a set of regulations to limit the spread of smoking, and many countries have bound themselves to follow the WHO's guidelines. This article provides an overview of these regulatory measures and the authors attempt to defend them from the perspective of liberty and autonomy. Their motivation is to countermand any attempt by the tobacco industry to attack the regulations on the grounds that they infringe the liberty rights of producers and consumers. It is also argued, however, that a blanket ban of the production, sale and consumption of tobacco cannot be justified on the grounds of autonomy alone. PMID:19482980

  2. Mitigating residential exposure to secondhand tobacco smoke

    NASA Astrophysics Data System (ADS)

    Klepeis, Neil E.; Nazaroff, William W.

    In a companion paper, we used a simulation model to explore secondhand tobacco smoke (SHS) exposures for typical conditions in residences. In the current paper, we extend this analysis to evaluate the effectiveness of physical mitigation approaches in reducing nonsmokers' exposure to airborne SHS particulate matter in a hypothetical 6-zone house. Measures investigated included closing doors or opening windows in response to smoking activity, modifying location patterns to segregate the nonsmoker and the active smoker, and operating particle filtration devices. We first performed 24 scripted simulation trials using hypothetical patterns of occupant location. We then performed cohort simulation trials across 25 mitigation scenarios using over 1000 pairs of nonsmoker and smoker time-location patterns that were selected from a survey of human activity patterns in US homes. We limited cohort pairs to cases where more than 10 cigarettes were smoked indoors at home each day and the nonsmoker was at home for more than two thirds of the day. We evaluated the effectiveness of each mitigation approach by examining its impact on the simulated frequency distribution of residential SHS particle exposure. The two most effective strategies were the isolation of the smoker in a closed room with an open window, and a ban on smoking whenever the nonsmoker was at home. The use of open windows to supply local or cross ventilation, or the operation of portable filtration devices in smoking rooms, provided moderate exposure reductions. Closed doors, by themselves, were not effective.

    Tobacco use and tobacco smoke exposure are among the most important health threats to children, adolescents, and adults. There is no safe level of tobacco smoke exposure. The developing brains of children and adolescents are particularly vulnerable to the development of tobacco and nicotine dependence. Tobacco is unique among consumer products in that it causes disease and death when used exactly as intended. Tobacco continues to be heavily promoted to children and young adults. Flavored and alternative tobacco products, including little cigars, chewing tobacco, and electronic nicotine delivery systems are gaining popularity among youth. This statement describes important evidence-based public policy actions that, when implemented, will reduce tobacco product use and tobacco smoke exposure among youth and, by doing so, improve the health of children and young adults.

    Worldwide tobacco smoking kills nearly 6 million people each year, including more than 600,000 non-smokers who die from smoke exposure. Environmental tobacco smoke (ETS, also called secondhand smoke, involuntary smoke, or passive smoke) is the combination of sidestream smoke, the smoke given off by a burning tobacco product and mainstream smoke, the smoke exhaled by smokers. People may be exposed to ETS in homes, cars, workplaces, and public places, such as bars, restaurants, and recreational settings. In addition, there is another type of smoke which until now has not been recognized: the so-called thirdhand smoke, that comes from the reaction of mainstream smoke and environmental nitrous acid (HNO2) making carcinogenic tobacco-specific nitrosamines (TSNAs). The effects of ETS on human health are well-known, passive smoking is harmful to those who breathe the toxins and it is a serious problem for public health. The smoking ban in Italy had reduced ETS pollution, as in the United States and in other countries all over the world. However, the implementation of comprehensive legislation on smoking policy will necessitate other tobacco control measures for its successful fulfillment: increased media awareness, telephone smoking cessation helplines and smoking cessation support services could be an opportunity to ensure awareness, comprehension and support to those who want to quit smoking. The effectiveness of legislative efforts will also depend on successful enforcement of smoking bans and compliance with the legislation. This review summarizes the evidences about the effect of ETS and provides an overview of smoke-free laws and policies. PMID:24217845

    In this paper review of chromatographic techniques and detectors used to analyse nicotine and its metabolites has been presented. The chromatographic determination of xenobiotics in biological material is usually proceeded by multistage isolation procedures, using liquid-liquid and liquid-solid extraction in various modifications. In our investigations, planar chromatography with densitometry has been used to identify and quantify nicotine and its metabolites in body fluids for assessment of tobacco smoke exposure. This technique does not require special cleanup techniques and as well is economic and environmental friendly. PMID:16521991

  6. Minerals, Tobacco and Smoking-Related Disease

    NASA Astrophysics Data System (ADS)

    Stephens, W. E.

    2003-12-01

    As much as 8% (by dry weight) of commercial tobacco is mineral, and the view that minerals are inert, playing no more than a passive role in smoking-related disease, is challenged. An inventory of minerals in tobacco is presented and an interpretation of their sources given. Using elemental abundances the relative contributions of natural and anthropogenic sources to the commercial product is quantitatively modelled relative to average crustal abundances. A framework is presented for investigating the potential ways in which minerals with, or acquire, toxic properties behave in the smoking environment. In order to represent a potential hazard any mineral (or mineral reaction product) with suspected toxic properties must partition into smoke and be respirable. For inhalation a significant proportion of the particles must be smaller than 10 microns. Three categories of potential hazard are recognised: 1. Minerals with intrinsic toxic properties. Quartz can amount to 1% or more in some cigarettes and is defined as a human carcinogen by the IARC. It is not likely to represent a hazard as its grain size is probably too coarse to be respirable. However talc, also a Type 1 carcinogen when it is contaminated with asbestos, is a common constituent of cigarette paper and may be of respirable size. Some other minerals also fall into this category. 2. Minerals that generate toxic products on combustion. Examples are the biominerals calcium oxalate monohydrate (whewellite) and dihydrate (weddellite), which amount to about 5 wt% of popular UK brands. These minerals decompose at tobacco combustion temperatures yielding large quantities of carbon monoxide. A substantial fraction of the CO budget of UK cigarettes may derive from this source. 3. Minerals that acquire toxic properties on combustion. Little is known about free radical generation on mineral surfaces during tobacco combustion, but the devolatilisation of calcic phases (carbonates and oxalates) creates oxide particles with surfaces highly adsorbent to polycyclic aromatic hydrocarbons (PAH). Calcic mineral particles are two orders of magnitude more abundant in smokers' lungs compared with non-smoking controls in residents of Vancouver. Such particles may thus be potential agents for the delivery of PAH carcinogens, including benzo(a)pyrene, to the lungs. None of the potential hazards listed above has yet been properly evaluated.

    Objectives. This report describes the history, true goals, and effects of tobacco industry–sponsored youth smoking prevention programs. Methods. We analyzed previously-secret tobacco industry documents. Results. The industry started these programs in the 1980s to forestall legislation that would restrict industry activities. Industry programs portray smoking as an adult choice and fail to discuss how tobacco advertising promotes smoking or the health dangers of smoking. The industry has used these programs to fight taxes, clean-indoor-air laws, and marketing restrictions worldwide. There is no evidence that these programs decrease smoking among youths. Conclusions. Tobacco industry youth programs do more harm than good for tobacco control. The tobacco industry should not be allowed to run or directly fund youth smoking prevention programs. PMID:12036777

    Tobacco smoking (i.e. cigarettes, rolled tobacco, pipes, etc.) is associated with significant health risks, reduced life expectancy and negative personal and societal economic impact. Smokers have an increased risk of cancer (i.e. lung, throat, bladder), chronic obstructive pulmonary disease (COPD), tuberculosis and cardiovascular disease (i.e. stroke, heart attack). Smoking affects unborn babies, children and others exposed to second hand smoke. Stopping or 'quitting' is not easy. Nicotine is highly addictive and smoking is frequently associated with social activities (e.g. drinking, eating) or psychological factors (e.g. work pressure, concerns about body weight, anxiety or depressed mood). The benefits of quitting, however, are almost immediate, with a rapid lowering of blood pressure and heart rate, improved taste and smell, and a longer-term reduction in risk of cancer, heart attack and COPD. Successful quitting requires attention to both the factors surrounding why an individual smokes (e.g. stress, depression, habit, etc.) and the symptoms associated with nicotine withdrawal. Many smokers are not ready or willing to quit and require frequent motivational input outlining the benefits that would accrue. In addition to an evaluation of nicotine dependence, co-existent medical or psychiatric conditions and barriers to quitting should be identified. A tailored approach encompassing psychological and social support, in addition to appropriate medication to reduce nicotine withdrawal, is likely to provide the best chance of success. Relapse is not uncommon and reasons for failure should be addressed in a positive manner and further attempts initiated when the individual is ready.Key steps in smoking cessation include: (i) identifying all smokers, alerting them to the harms of smoking and benefits of quitting; (ii) assessing readiness to initiate an attempt to quit; (iii) assessing the physical and psychological dependence to nicotine and smoking; (iv) determining the best combination of counselling/support and pharmacological therapy; (v) setting a quit date and provide suitable resources and support; (vi) frequent follow-up as often as possible via text/telephone or in person; (vii) monitoring for side-effects, relapse and on-going cessation; and (viii) if relapse occurs, providing the necessary support and encourage a further attempt when appropriate.

  9. Modeling residential exposure to secondhand tobacco smoke

    NASA Astrophysics Data System (ADS)

    Klepeis, Neil E.; Nazaroff, William W.

    We apply a simulation model to explore the effect of a house's multicompartment character on a nonsmoker's inhalation exposure to secondhand tobacco smoke (SHS). The model tracks the minute-by-minute movement of people and pollutants among multiple zones of a residence and generates SHS pollutant profiles for each room in response to room-specific smoking patterns. In applying the model, we consider SHS emissions of airborne particles, nicotine, and carbon monoxide in two hypothetical houses, one with a typical four-room layout and one dominated by a single large space. We use scripted patterns of room-to-room occupant movement and a cohort of 5000 activity patterns sampled from a US nationwide survey. The results for scripted and cohort simulation trials indicate that the multicompartment nature of homes, manifested as inter-room differences in pollutant levels and the movement of people among zones, can cause substantial variation in nonsmoker SHS exposure.

  10. Determination of tobacco smoking influence on volatile organic compounds constituent by indoor tobacco smoking simulation experiment

    Tobacco smoking simulation experiment was conducted in a test room under different conditions such as cigarette brands, smoking number, and post-smoke decay in forced ventilation or in closed indoor environments. Thirty-seven chemical species were targeted and monitored, including volatile organic compounds (VOCs) and environmental tobacco smoke (ETS) markers. The results indicate that benzene, d-limonene, styrene, m-ethyltoluene and 1,2,4/1,3,5-trimethylbenzene are correlated well with ETS markers, but toluene, xylene, and ethylbenzene are not evidently correlated with ETS markers because there are some potential indoor sources of these compounds. 2,5-dimethylfuran is considered to be a better ETS marker due to the relative stability in different cigarette brands and a good relationship with other ETS markers. The VOCs concentrations emitted by tobacco smoking were linearly associated with the number of cigarettes consumed, and different behaviors were observed in closed indoor environment, of which ETS markers, d-limonene, styrene, trimethylbenzene, etc. decayed fast, whereas benzene, toluene, xylene, ethylbenzene, etc. decayed slowly and even increased in primary periods of the decay; hence ETS exposure in closed environments is believed to be more dangerous. VOCs concentrations and the relative percentage constituent of ETS markers of different brand cigarettes emissions vary largely, but the relative percentage constituent of ETS markers for the same brand cigarette emissions is similar.

    Prior to implementing a shipwide no-smoking policy, the crew of U.S.S. Theodore Roosevelt (CVN 71) participated in a voluntary survey on tobacco-related matters. The survey queried participants on their tobacco-use history, subjective exposure to environmental tobacco smoke (ETS), and attitudes related to smoking policy prior to the cessation of all smoking activities aboard ship. Of the 2,221 crewmembers who participated (74% response rate), 36% classified themselves as current cigarette smokers. Nonsmokers estimated their general exposure to ETS between "low" to "moderate." Of all participants, 57% were in favor of the current restricted smoking policy, including 18% of currently smoking personnel. Follow-up research is being conducted to assess the long-term impact of the no-smoking policy on changes in attitudes regarding policy, tobacco-use rates, and ETS exposure. PMID:7695554

    1988-12-01

    The ability of room air cleaners to remove gases and particles from air contaminated with tobacco smoke has been studied. Thirty-one air cleaners were tested. Various air-cleaning devices were used, ie, electrostatic precipitators, electret fiber filters, ionizers, activated carbon, impregnated alumina, ionizing lamps, and an electron generator. The airflow rates were in the range of 0-500 m3/h. The measurements covered particle sizes of 0.01-7.5 microns and the following gases: carbon monoxide, ammonia, formaldehyde, nitric oxide, nitrogen dioxide, hydrocarbons, and hydrogen cyanide. No formal standard procedure exists for testing room air cleaners; therefore the tests were made in the following way. Tobacco smoke was generated and mixed in a closed room. The room air cleaner was started, and the decay rates for the gases and particles were measured. The results were calculated as equivalent airflow rates, ie, the clean airflow rate causing the same decay rate for contaminant concentrations in a room. The equivalent airflow rates were 0-360 m3/h. The rate of ozone emission by electrostatic precipitators and ionizers was also measured. One general conclusion was that it is much more difficult to remove gases than particles. PMID:3212415

    2015-11-01

    Tobacco dependence starts in childhood. Tobacco exposure of children is common and causes illness and premature death in children and adults, with adverse effects starting in the womb. There is no safe level of tobacco smoke exposure. Pediatricians should screen for use of tobacco and other nicotine delivery devices and provide anticipatory guidance to prevent smoking initiation and reduce tobacco smoke exposure. Pediatricians need to be aware of the different nicotine delivery systems marketed and available.Parents and caregivers are important sources of children's tobacco smoke exposure. Because tobacco dependence is a severe addiction, to protect children's health, caregiver tobacco dependence treatment should be offered or referral for treatment should be provided (such as referral to the national smoker's quitline at 1-800-QUIT-NOW). If the source of tobacco exposure cannot be eliminated, counseling about reducing exposure to children should be provided.Health care delivery systems should facilitate the effective prevention, identification, and treatment of tobacco dependence in children and adolescents, their parents, and other caregivers. Health care facilities should protect children from tobacco smoke exposure and tobacco promotion. Tobacco dependence prevention and treatment should be part of medical education, with knowledge assessed as part of board certification examinations. PMID:26504137

    The paper demonstrates that integrated chemical and bacterial mutagenicity information can be used to identify environmental tobacco smoke genotoxicants, monitor human exposure, and make comparative assessments. Approximately one-third of the environmental tobacco-smoke constituents for which there is quantitative analytical-chemistry information also have associated genotoxicity information. For example, 11 of the quantitated compounds are animal carcinogens. Work presented in this paper demonstrates that both the nonparticle-bound semi-volatile and the particulate-bound organic material contain bacterial mutagens. These environmental tobacco-smoke organics give an equivalent of about 86,000 revertants per cigarette. In addition, this article summarizes efforts to estimate environmental tobacco smoke bacterial mutagenicity, to use bacterial tests for the monitoring of environmental tobacco smoke-impacted indoor environments, and to use bacterial assays for the direct monitoring of human exposure.

    College campus tobacco-free policies are an emerging trend. Between September 2013 and May 2014, we surveyed 1309 college students at 8 public 4-year institutions across California with a range of policies (smoke-free indoors only, designated outdoor smoking areas, smoke-free, and tobacco-free). Stronger policies were associated with fewer students reporting exposure to secondhand smoke or seeing someone smoke on campus. On tobacco-free college campuses, fewer students smoked and reported intention to smoke on campus. Strong majorities of students supported outdoor smoking restrictions across all policy types. Comprehensive tobacco-free policies are effective in reducing exposure to smoking and intention to smoke on campus. PMID:25521901

  20. Tobacco Industry Strategies to Minimize or Mask Cigarette Smoke: Opportunities for Tobacco Product Regulation

    PubMed Central

    Rees, Vaughan W.

    2013-01-01

    Introduction: The tobacco industry has developed technologies to reduce the aversive qualities of cigarette smoke, including secondhand smoke (SHS). While these product design changes may lessen concerns about SHS, they may not reduce health risks associated with SHS exposure. Tobacco industry patents were reviewed to understand recent industry strategies to mask or minimize cigarette smoke from traditional cigarettes. Methods: Patent records published between 1997 and 2008 that related to cigarette smoke were conducted using key word searches. The U.S. Patent and Trademark Office web site was used to obtain patent awards, and the World Intellectual Property Organizations Patentscope and Free Patents Online web sites were used to search international patents. Results: The search identified 106 relevant patents published by Japan Tobacco Incorporated, British America Tobacco, Philip Morris International, and other tobacco manufacturers or suppliers. The patents were classified by their intended purpose, including reduced smoke constituents or quantity of smoke emitted by cigarettes (58%, n = 62), improved smoke odor (25%, n = 26), and reduced visibility of smoke (16%, n = 18). Innovations used a variety of strategies including trapping or filtering smoke constituents, chemically converting gases, adding perfumes, or altering paper to improve combustion. Conclusions: The tobacco industry continues to research and develop strategies to reduce perceptions of cigarette smoke, including the use of additives to improve smoke odor. Surveillance and regulatory response to industry strategies to reduce perceptions of SHS should be implemented to ensure that the public health is adequately protected. PMID:22949571

    The microbiological composition of tobacco products was studied using culture and chemical analysis (of tobacco leaves) or chemical analysis only (tobacco and tobacco smoke). The chemical analyses utilized gas chromatography-tandem mass spectrometry for determining 3-hydroxy fatty acids, muramic acid, and ergosterol as markers of respectively lipopolysaccharide (LPS), peptidoglycan, and fungal biomass. Mesophilic bacteria dominated in both fresh and cured tobacco leaves; a range of additional bacteria and fungi were also found albeit in minor amounts. The peptidoglycan and LPS concentrations were approximately the same in tobacco leaves as in cigarette tobacco. The concentrations of the measured microbial components were much lower in some cigarettes locally produced in China, Korea, and Vietnam than in cigarettes of international brands purchased in the same countries, and the concentrations in the smoke were in general agreement with the concentrations in cigarette tobacco. No differences in microbial load in tobacco of "light" and "full flavor" cigarettes were seen. Storing cigarettes at high humidity resulted in elevated levels of fungi in the cigarette tobacco leading to increased ergosterol concentrations in the smoke. The fact that tobacco smoke is a bioaerosol may help to explain the high prevalence of respiratory disorders among smokers and non-smokers exposed to second hand smoke since the same symptoms are also commonly associated with exposure to bioaerosols.

    Objectives To estimate the population attributable fraction (PAF) and numbers of cancers occurring in Australia in 2010 attributable to tobacco smoking, both personal and by a partner. Methods We used a modified Peto-Lopez approach to calculate the difference between the number of lung cancer cases observed and the number expected assuming the entire population developed lung cancer at the same rate as never smokers. For cancers other than lung, we applied the standard PAF formula using relative risks from a large cohort and derived notional smoking prevalence. To estimate the PAF for partners' smoking, we used the standard formula incorporating the proportion of non-smoking Australians living with an ever-smoking partner and relative risks associated with partner smoking. Results An estimated 15,525 (13%) cancers in Australia in 2010 were attributable to tobacco smoke, including 8,324 (81%) lung, 1,973 (59%) oral cavity and pharynx, 855 (60%) oesophagus and 951 (6%) colorectal cancers. Of these, 136 lung cancers in non-smokers were attributable to partner tobacco smoke. Conclusions More than one in eight cancers in Australia is attributable to tobacco smoking and would be avoided if nobody smoked. Implications Strategies to reduce the prevalence of smoking remain a high priority for cancer control. PMID:26437733

  9. Respiratory irritation from environmental tobacco smoke.

    PubMed

    Shephard, R J

    1992-01-01

    Acute physiological and chronic pathological responses of the respiratory tract to environmental tobacco smoke (ETS) are reviewed briefly. This study excludes discussion of the possible risk of lung cancer and the known impact of carbon monoxide on the fetus and adult. In some environments, the dose of particulate matter and the concentrations of irritant vapors absorbed on the ETS particles reach a level for which a physiological response may be expected, not only in the nose but also the bronchi. However, direct measurements indicate only small increases of nasal and bronchial resistance if normal subjects are exposed to maximal, likely concentrations of ETS. ETS is readily detected by the nonsmoker, but there is no strong evidence that pulmonary reactions have a psychogenic basis. The condition of approximately 20% of asthmatic patients is exacerbated by ETS exposure. Further study is needed to clarify the likelihood that adults will progress from a minor physiological response to pathological reactions, e.g., chronic obstructive lung disease. In young children (who are less able to escape from ETS), the association between exposure and an increase in respiratory disease is stronger than in adults. Exacerbation of asthma and an increase of respiratory disease are further arguments for legislation to guarantee smoke-free air to the nonsmoking public. PMID:1567235

    PubMed

    Hoffmann, D; Adams, J D; Piade, J J; Hecht, S S

    1980-01-01

    The yields of volatile N-nitrosamines in cigarette smoke are primarily dependent upon the nitrate content of the tobacco and, to some extent, on the protein content. Cellulose acetate tips, such as those found on most commercial filter cigarettes, selectively remove at least 70% of the volatile N-nitrosamines, independently of the pH of the weakly acidic or weakly alkaline smoke. So far, three tobacco-specific N-nitrosamines have been detected in tobacco and tobacco smoke. During tobacco processing and smoking, N'-nitrosonornicotine is formed by nitrosation of nicotine and, to a minor degree, by nitrosation of nornicotine, whereas 4-(N-methyl-N-nitrosamino)-1-(3-pyridyl)-1-butanone originates from oxidative nitrosation of nicotine. N'-Nitrosoanatabine is formed by nitrosation of the second most abundant tobacco alkaloid, anatabine. The tobacco-specific N-nitrosamines in the smoke arise partly from the tobacco by transfer and partly by nitrosation of the alkaloids during smoking (pyrosynthesis). Preliminary results indicate that cellulose acetate filter tips may selectively remove considerable amounts of the nonvolatile nitrosamines from the smoke. PMID:7228275

    The composition of cigarette smoke in spite of its tremendous complexity is relatively known, but little is known about the influence of Ecologic Factors (air flows, temperature, light) on the Migration Character of individual and specific components of Tobacco Smoke constansate in environmental atmosphere on different distance from burning cigarette. Oxidation in air, and photochemical reactions can produce many compounds which were not originally present in the Tobacco Smoke. Gas liquid Chromatography with high-resolution capillary column is applied. The tobacco skome volume was taked and analyzed in the distance of 2,0 m and 4,0 m from burning cigarette. The content of naphthalene and its derivates in the air samples was revealed. Our data show that distance of exposition from burning cigarette can change the structure and volume of each component of tobacco smoke. The studies are necessary in different direction. First, this phenomen still needs to be explained. The second, it would be interesting to investigate the retention of tobacco smoke components in lung tissue, for a considerable time after the smoking process. The obtained data is very important from the point of ecological assessment of the environment and sensitivity to the components of tobacco smoke. PMID:26870983

    2015-01-01

    The substantial harmful effects of tobacco smoking on fertility and reproduction have become apparent but are not generally appreciated. Tobacco smoke contains more than 4000 kinds of constituents, including nicotine, tar, carbonic monoxide, polycyclic aromatic hydrocarbons, and heavy metals. Because of the complexity of tobacco smoke components, the toxicological mechanism is notably complicated. Most studies have reported reduced semen quality, reproductive hormone system dysfunction and impaired spermatogenesis, sperm maturation, and spermatozoa function in smokers compared with nonsmokers. Underlying these effects, elevated oxidative stress, DNA damage, and cell apoptosis may play important roles collaboratively in the overall effect of tobacco smoking on male fertility. In this review, we strive to focus on both the phenotype of and the molecular mechanism underlying these harmful effects, although current studies regarding the mechanism remain insufficient.

    2012-01-01

    Background While Italy has implemented some tobacco control policies over the last few decades, which resulted in a decreased smoking prevalence, there is still considerable scope to strengthen tobacco control policies consistent with the World Health Organization (WHO) policy guidelines. The present study aims to evaluate the effect of past and project the effect of future tobacco control policies on smoking prevalence and associated premature mortality in Italy. Methods To assess, individually and in combination, the effect of seven types of policies, we used the SimSmoke simulation model of tobacco control policy. The model uses population, smoking rates and tobacco control policy data for Italy. Results Significant reductions of smoking prevalence and premature mortality can be achieved through tobacco price increases, high intensity media campaigns, comprehensive cessation treatment program, strong health warnings, stricter smoke-free air regulations and advertising bans, and youth access laws. With a comprehensive approach, the smoking prevalence can be decreased by as much as 12% soon after the policies are in place, increasing to a 30% reduction in the next twenty years and a 34% reduction by 30?years in 2040. Without effective tobacco control policies, a total of almost 300 thousand lives will be prematurely lost due to smoking by the year 2040. Conclusion Besides presenting the benefits of a comprehensive tobacco control strategy, the model helps identify information gaps in surveillance and evaluation schemes that will promote the effectiveness of future tobacco control policy in Italy.

    In Poland approximately 33% adults are active smokers. Both active smoking and passive exposition to tobacco smoke leads to serious diseases and causes many other problems. This is why the decrease of smoking prevalence seems to be one of the most important targets of contemporary medicine. In this task the attitude of medical staff plays a great role (prevention, education, behaviour of a medical employee as a positive example). The research was carried out among 48 employees of Regional Station of Ambulance Service in Poznan (16 physicians, 19 medical rescuers and 13 nurses). The group comprised 21 women and 27 men. The investigative tool was a questionnaire concerning smoking, passive exposition to tobacco smoke and attitude of the examined persons towards smoking. We found that smoking prevalence in the investigated group considerably exceeds the average values for Polish population (particularly the number of smoking women) whereas passive exposition to tobacco smoke affects everyone in this group. In the opinion of the examined people the main factors inducing and maintaining tobacco smoking are: addiction, pleasure connected with smoking or influence of someone's company. In a case of medical personnel tobacco smoking (similarly to other behaviours which are harmful for someone's health) weakens the authority of a health care provider as an example of health promotion.

    2014-09-01

    Water pipe smoking (WPS), an old method of tobacco smoking, is re-gaining widespread popularity all over the world and among various populations. Smoking machine studies have shown that the water pipe (WP) mainstream smoke (MSS) contains a wide array of chemical substances, many of which are highly toxic and carcinogenic for humans. The concentrations of some substances exceed those present in MSS of cigarettes. Despite being of low grade, current evidence indicates that WPS is associated with different adverse health effects, not only on the respiratory system but also on the cardiovascular, hematological, and reproductive systems, including pregnancy outcomes. In addition, association between WPS and malignancies, such as lung, oral and nasopharyngeal cancer, has been suggested in different studies and systematic reviews. Despite its long standing history, WPS research still harbors a lot of deficiencies. The magnitude of toxicants and carcinogen exposures, effects on human health, as well as the addiction and dependence potentials associated with WPS need to be studied in well-designed prospective trials. Unfortunately, many of the tobacco control and clean indoor policies have exempted water pipes. World wide awareness among the public, smokers, and policymakers about the potential health effects of WPS is urgently required. Furthermore, stringent policies and laws that control and ban WPS in public places, similar to those applied on cigarettes smoking need to be implemented. PMID:25130679

    2013-01-01

    The tobacco industry has adapted its promotional strategies as tobacco-control measures have increased. This paper describes the tobacco industry's strategies on smoking manners and illustrates how these interfere with tobacco-control policy in Japan where tobacco control remains weak. Information on the tobacco industry's promotional strategies in Japan was collected through direct observation, a review of tobacco industry documents and a literature review. The limitation of the study would be a lack of industry documents from Japan as we relied on a database of a U.S. institution to collect internal documents from the tobacco industry. Japan Tobacco began using the manners strategies in the early 1960s. Collaborating with wide range of actors -including local governments and companies- the tobacco industry has promoted smoking manners to wider audiences through its advertising and corporate social responsibility activities. The tobacco industry in Japan has taken advantage of the cultural value placed on manners in Japan to increase the social acceptability of smoking, eventually aiming to diminish public support for smoke-free policies that threatens the industry's business. A stronger enforcement of the WHO Framework Convention on Tobacco Control is critical to counteracting such strategies. PMID:24598274

    Tobacco smoking is an important problem among schoolchildren. The authors studied the patterns of tobacco smoking among schoolchildren in Colombo, Sri Lanka, using a self-administered questionnaire. Multistaged stratified random sampling was used to select 6000 students. Response rate was 90.7% (5446), out of which 53.4% were males. Prevalence rates for males and females, respectively, were as follows: having smoked at least 1 complete cigarette: 27.0% and 13.3%, smoked more than 100 cigarettes: 2.3% and 0.3%, daily smoking: 1.8% and 0.2%. Mean age of starting to smoke was 14.16 years. The tobacco products most used were cigarettes (91.5%) and bidis (3.8%). In univariate analysis, male gender, parental smoking, studying non-science subjects, peer smoking, and participating in sports were significantly associated with smoking of at least 1 complete cigarette (P <.05). In multivariate analysis, the most significant correlates were having close friends (odds ratio = 3.29, confidence interval = 2.474.37) or parents who smoked (odds ratio = 1.86, confidence interval = 1.282.71). Female smoking has increased from previously reported values. These high-risk groups can be targets for preventive programs. PMID:22426558

    The aim of a review is to examine the current state of the relevant publications on tobacco smoking, the Guidelines on Protection from Exposure to Tobacco Smoke, and WHO Framework Convention on Tobacco Control (FCTC), which commits countries to protect the public's health by adopting various measures to reduce demand for tobacco. Georgia ratified the treaty in February 2006. In Georgia the implementation of the WHO FCTC is regulated by the "Law on Tobacco Control" (Law). It went into effect in September 2003. Changes and additions to the Law were approved by the Parliament in December 2008 (N 941 - rs) and in December 2010 (№4059-rs). According to Article 10 of the Law, smoking is prohibited at the educational and childcare institutions, medical and pharmaceutical facilities, at the entire area of petrol, gas and gas-distribution stations, in public transport, indoor areas of work and mass gathering... In spite of the legislation rights of non-smokers are very poorly preserved. With this in mind, the Welfare Foundation, the FCTC and the Tobacco Control Alliance, organized a public discussion on enforcing smoke-free laws in Georgia, in December 2012 at Tbilisi Marriott Courtyard Hotel. In order to make public libraries, educational, cultural institutions «de jure» and «de facto» free from tobacco smoke, the campaign against tobacco, which aims to strengthen implementation of the Tobacco Control Law and Regulation should be held in public libraries - not in the hotels. It is necessary to hang a poster - «Environment free from Smoke» at the entrance to buildings where smoking is prohibited throughout. In Rules and regulations for the use of the library there must be a note: smoking is prohibited in the library. We hope that Georgia in the nearest future will be in the list of countries with smoke-free public and work places. PMID:23482366

    Introduction: Most correctional facilities have implemented tobacco restrictions in an effort to reduce costs and improve prisoner health, but little has been done to evaluate the impact of these policy changes. Patterns of tobacco use among prisoners were explored to determine the impact of incarceration in a facility with an indoor smoking ban on tobacco use behaviors. Methods: Recently incarcerated male inmates (n = 200) were surveyed about their tobacco use prior to and during incarceration. Results: Tobacco use was prevalent prior to arrest (77.5%) and increased during incarceration (81.0%). Though the number of cigarette smokers increased during imprisonment, per-capita cigarette consumption declined by 7.1 cigarettes/day (p < .001). Despite widespread tobacco use, most participants recognized that smoking is a cause of lung cancer (96.0%) and heart disease (75.4%) and that it can be addicting (97.5%). Most tobacco users (70.0%) reported a desire to quit, with 63.0% saying they intended to try quitting in the next year. Conclusions: Indoor smoking bans do not promote cessation in prisons but may reduce the amount of tobacco consumed. Though smoking is commonplace in prisons, most prisoners recognize the risks involved and wish to quit. This creates an ideal setting for intervention. Evidence-based cessation assistance should be made freely available to all incarcerated smokers. PMID:21447838

    Introduction Electronic cigarette (e-cigarette) use is increasing rapidly, and the impact on youth is unknown. We assessed associations between e-cigarette use and smoking intentions among US youth who had never smoked conventional cigarettes. Methods We analyzed data from the nationally representative 2011, 2012, and 2013 National Youth Tobacco Surveys of students in grades 6–12. Youth reporting they would definitely not smoke in the next year or if offered a cigarette by a friend were defined as not having an intention to smoke; all others were classified as having positive intention to smoke conventional cigarettes. Demographics, pro-tobacco advertisement exposure, ever use of e-cigarettes, and ever use of other combustibles (cigars, hookah, bidis, kreteks, and pipes) and noncombustibles (chewing tobacco, snuff, dip, snus, and dissolvables) were included in multivariate analyses that assessed associations with smoking intentions among never-cigarette-smoking youth. Results Between 2011 and 2013, the number of never-smoking youth who used e-cigarettes increased 3-fold, from 79,000 to more than 263,000. Intention to smoke conventional cigarettes was 43.9% among ever e-cigarette users and 21.5% among never users. Ever e-cigarette users had higher adjusted odds for having smoking intentions than never users (adjusted odds ratio = 1.70, 95% confidence interval = 1.24–2.32). Those who ever used other combustibles, ever used noncombustibles, or reported pro-tobacco advertisement exposure also had increased odds for smoking intentions. Conclusion In 2013, more than a quarter million never-smoking youth used e-cigarettes. E-cigarette use is associated with increased intentions to smoke cigarettes, and enhanced prevention efforts for youth are important for all forms of tobacco, including e-cigarettes. PMID:25143298

  4. Why the tobacco industry fears the passive smoking issue.

    The tobacco industry has identified the passive smoking issue as the single most important problem confronting its economic future. During the 1980s, the industry has been engaged in an elaborate and expensive international campaign seeking to refute the evidence against passive smoking's effects on health and to position the issue as one essentially concerned with civil liberties and smokers' "rights." There are three main reasons for the industry's concern: first, the passive smoking issue allows a widening of the definition of smoking beyond its discussion as a personal habit, legitimizing it as a social problem; second, successful cases of litigation against employers by workers with histories of chronic exposure to environmental tobacco smoke have created an industrial climate of concern leading to workplace smoking restrictions and bans, and third, the proliferation of smoking restrictions reduces smoking opportunities and thus reduces total cigarette consumption and hence financial returns to the industry. Based on the results of a large Australian study of a workplace smoking ban, an estimated 654.88 million cigarettes with a retail value of $A6,549 thousand would be forgone annually in Australia alone if 50 percent of white-collar worksites were to ban smoking. Finally, the passive smoking issue can be considered a Trojan horse to its less discussed effects: the reduced morbidity and mortality likely to result in smokers from the significant reductions in smoking frequency that occur with the proliferation of smoking restrictions introduced in the name of concern for the health of nonsmokers.

    Tobacco smoke contains thousands of xenobiotics harmful to human health. Their irritant, toxic and carcinogenic potential has been well documented. Passive smoking or exposure to second-hand smoke (SHS) in public places, including workplace, poses major medical problems. Owing to this fact there is a strong need to raise workers' awareness of smoking-related hazards through educational programs and to develop and implement legislation aimed at eliminating SHS exposure. This paper presents a review of reports on passive exposure to tobacco smoke and its impact on human health and also a review of binding legal regulations regarding smoking at workplace in Poland. It has been proved that exposure to tobacco smoke during pregnancy may lead to, e.g., preterm delivery and low birth weight, sudden infant death syndrome, lung function impairment, asthma and acute respiratory illnesses in the future. Exposure to tobacco smoke, only in the adult age, is also considered as an independent risk factor of cardiovascular diseases, acute and chronic respiratory diseases and cancer. Raising public awareness of tobacco smoke harmfulness should be a top priority in the field of workers' health prevention. Occupational medicine physicians have regular contacts with occupationally active people who smoke. Thus, occupational health services have a unique opportunity to increase employees and employers' awareness of adverse health effects of smoking and their prevention. PMID:26674169

  6. Assessment of the carcinogenic N-nitrosodiethanolamine in tobacco products and tobacco smoke

    A simple, reproducible gas chromatography-thermal energy analyzer (g.c.-TEA) method has been developed for the analysis of N-nitrosodiethanolamine (NDELA) in tobacco and tobacco smoke. The extract of tobacco or the trapped particulates of tobacco smoke are chromatographed on silica gel. The NDELA containing fractions are concentrated, silylated and analyzed with a modified g.c.-TEA system. (/sup 14/C)NDELA serves as internal standard for the quantitative analysis. Experimental cigarettes made from tobaccos which were treated with the sucker growth inhibitor maleic hydrazidediethanolamine (MH-DELA) contained 115--420 p.p.b. of NDELA and their smoke contained 20--290 ng/cigarette, whereas hand-suckered tobacco and its smoke were free of NDELA. The tobacco of US smoking products contained 115--420 p.p.b. of NDELA and the mainstream smoke from such products yielded 10--68 ng/cigar or cigarette. NDELA levels in chewing tobacco ranged from 220--280 p.p.b. and in two commercial snuff products were 3,200 and 6,800 p.p.b. Although the five analyzed MH-DELA preparations contained between 0.6--1.9 p.p.m. NDELA it is evident that the major portion of NDELA in tobacco is formed from the DELA residue during the tobacco processing. Based on bioassay data from various laboratories which have shown that NDELA is a relatively strong carcinogen and based on the results of this study the use of MH-DELA for the cultivation of tobacco is questioned.

    Stem cells are thought to persist throughout human life possessing enormous capacity for proliferation and differentiation. These cells and their microenvironment are potential targets for environmental pollutions, for example tobacco smoke. Tobacco smoke consists of thousands of substances which can disturb stem cell homeostasis by evoking, in particular, oxidative stress and hypoxia. It causes also deep, irreversible changes in the affected tissues. It is strongly linked with carcinogenesis. Skin is one of the most exposed tissues to tobacco smoke. Self-renewal dermal tissues, such as epidermis and its appendages, are composed of various stem cell populations. The tissue of the skin that is richest in SC is the hair follicle. In wound healing are involved: epidermal KSC population and stem populations from hair follicle, such as CD34+ and Lrig6+ cells. Some skin cancers, i.e., squamous cell carcinoma, originate from skin stem cells and are considered to be most associated with long-term smoking. Dermal stem cells can be affected by tobacco smoke components in two ways: internal, where xenobiotics are delivered with blood stream, and external, where the tissues are directly exposed to environmental tobacco smoke, as well as to third-hand smoke. Assessment of the dose- and time-response of the skin and dermal appendages to tobacco smoke exposure can allow to estimate the adverse health effects risk. Usually, to assess tobacco smoke exposure time, hairs and toenails are used. This is because they have a unique ability to store xenobiotics for longer periods of time in respect to their temporal appearance in the blood. Current scientific and medical problem is searching for more adequate biomarkers for TS exposure assessment. The unresolved question is, if stem cells isolated from the skin and its appendages might be good biomarkers for tobacco smoke exposure. We should take into consideration stem cell biology (proliferation vs. differentiation), expression of specific markers, half-live, regenerative potential, signs of malignant transformation etc. For practical purposes, human stem cell populations from the epidermis, hair follicles and nails, their microenvironment and mutual relations should be well recognized. These cells might be an interesting source of information on tobacco smoke exposure. PMID:24501812

    The tobacco-derived environmental emission of most common concern is the smoke issuing from cigarettes between puffs. A review of smoke formation mechanisms, sampling methods, and selected emission factors suggests that sidestream deliveries are actually much less variable than is commonly thought. Examples of devices used to generate and collect sidestream smoke for analysis are described. Emissions computed as is common practice from sidestream/mainstream ratios are compared to those determined directly. 36 refs., 3 figs., 2 tabs.

    Objectives. We investigated the frequency of alternative tobacco product use (loose leaf, moist snuff, snus, dissolvables, electronic cigarettes [e-cigarettes]) among smokers and the association with quit attempts and intentions. Methods. A nationally representative probability-based cross-sectional survey of 1836 current or recently former adult smokers was completed in November 2011. Multivariate logistic regressions evaluated associations between alternative tobacco product use and smoking cessation behaviors. Results. Of the smokers, 38% had tried an alternative tobacco product, most frequently e-cigarettes. Alternative tobacco product use was associated with having made a quit attempt, and those intending to quit were significantly more likely to have tried and to currently use the products than were smokers with no intentions to quit. Use was not associated with successful quit attempts. Interest in future use of alternative tobacco products was low, except for e-cigarettes. Conclusions. Alternative tobacco products are attractive to smokers who want to quit smoking, but these data did not indicate that alternative tobacco products promote cessation. Unsubstantiated overt and implied claims that alternative tobacco products aid smoking cessation should be prohibited. PMID:23488521

    In this narrative review, we explore the history of tobacco smoking, its associations and portrayal of its use with luxury and glamour in the past, and intriguingly, its subsequent transformation into a mass consumption industrialized product encouraged by advertising and film. Then, we describe the next phase where tobacco in parts of the world has become an unwanted product. However, the number of smokers is still increasing, especially in new markets, and increasingly younger individuals are being attracted to it, despite the well-known health consequences of tobacco use. We also explore current smoking behaviors, looking at trends in the prevalence of consumption throughout the world, discrimination against smokers, light and/or intermittent smokers, and the electronic cigarette (e-cigarette). We place these changes in the context of neuroscience, which may help explain why the cognitive effects of smoking can be important reinforcers for its consumption despite strong anti-smoking pressure in Western countries.

    A substantial number of the world's population continues to smoke tobacco, even in the setting of a cancer diagnosis. Studies have shown that patients with cancer who have a history of smoking have a worse prognosis than nonsmokers. Modulation of several physiologic processes involved in drug disposition has been associated with long-term exposure to tobacco smoke. The most common of these processes can be categorized into the effects of smoking on cytochrome P450-mediated metabolism, glucuronidation, and protein binding. Perturbation in the pharmacokinetics of anticancer drugs could result in clinically significant consequences, as these drugs are among the most toxic, but potentially beneficial, pharmaceuticals prescribed. Unfortunately, the effect of tobacco smoking on drug disposition has been explored for only a few marketed anticancer drugs; thus, little prescribing information is available to guide clinicians on the vast majority of these agents. The carcinogenic properties of several compounds found in tobacco smoke have been well studied; however, relatively little attention has been given to the effects of nicotine itself on cancer growth. Data that identify nicotine's effect on cancer cell apoptosis, tumor angiogenesis, invasion, and metastasis are emerging. The implications of these data are still unclear but may lead to important questions regarding approaches to smoking cessation in patients with cancer. PMID:23033231

    Aim Although tobacco smoke is an established risk factor for adult cancer, studies of the association between parental smoking and childhood cancer have produced inconsistent results. To investigate the transgenerational relationship between pre-natal and post-natal tobacco smoke exposure from the grandmothers pregnancies until after the post-natal period and childhood cancer. Methods Exposure to tobacco smoke was recorded for three generations. Data were collected through personal interviews using the paediatric environmental history, and were compared among 128 children with cancer and 128 matched controls. The contingency tables and a logistic multivariable regression model were used to control for possible confounding factors. Results Smoke exposure during oogenesis (maternal grandmother smokers) odds ratio (OR) 2.2 (95% confidence interval (CI) 1.14.9) and during the mother pregnancies OR 1.8 (95% CI 1.13.3) were significantly associated with an increased risk of childhood cancer. Conclusions Tobacco smoke exposure during the grandmothers and mothers pregnancies increase the risk of cancer in the descendants. The results suggest that the biological plausibility of the association between parental smoking and paediatric cancer can be explained by the large latency period of paediatric carcinogenesis.

    Objectives Nitric oxide (NO) is a reactive gas generated by inflammatory cells and mucosal epithelial cells of the nose and paranasal sinuses and is an important mediator in nonspecific host defense against infectious agents. However, NO also mediates physiologic events such as vasodilation, mucus hypersecretion, and mucosal disruption that are associated with inflammatory conditions, and it is a regulator of ciliary beat frequency. In the present study, we hypothesized that lifestyle exposure to tobacco smoke, whether through active smoking or by inadvertent exposure to secondhand tobacco smoke, would result in higher detectable levels of nasal NO (nNO) than are found in well-documented nonsmokers. Methods Nasal NO measurements were obtained concomitant with assays of urine cotinine from well-documented nonsmokers, active smokers, and individuals exposed by lifestyle to secondhand smoke. These parameters were statistically analyzed to determine whether increasing levels of tobacco smoke exposure yield higher concentrations of nNO. Results Our results and subsequent statistical analyses imply that active smokers who exhibit high urine cotinine levels exhibit significant increases in nNO levels in comparison to both nonsmokers and nonsmokers exposed to secondhand smoke. Conclusions There is an increased level of nNO associated with tobacco smoke exposure that may contribute to the inflammatory processes characteristic of disease pathogenesis in smokers.

    OBJECTIVE: To further our understanding of the workplace smoking policies and smoking cessation practices of physicians in Nigeria. DESIGN: Cross-sectional survey distributed to 619 physicians practicing in two teaching hospitals in southwestern Nigeria. PARTICIPANTS: Three-hundred-seventy-three physicians who returned completed surveys. MAIN OUTCOME MEASURES: Physician's self-reported workplace smoking policies, attitudes toward smoking cessation, and use of recommended smoking cessation guidelines/policies. RESULTS: Physicians rated quitting as "extremely important." The majority assessed their patients smoking status over the past three months (81%) and thought counseling smokers would help them quit (95%). However, < 1% prescribed pharmacotherapy for smoking cessation in the last three months. Significant differences were found in the workplace smoking policies of the two teaching hospitals (p < 0.001). Differences were also found in the attitudes and smoking cessation practices of physicians in Hospital A and Hospital B. CONCLUSIONS: Physicians are aware of smoking and the importance of quitting but few have guidelines/policies to assist their patients with quitting. Workplace smoking policies appear to impact the smoking cessation attitudes and practices of physicians in Nigeria. Encouraging the adoption of workplace smoking restrictions, as well as training physicians to use recommended smoking cessation interventions, is critical to addressing the tobacco epidemic in Nigeria.

  20. How Menthol Alters Tobacco-Smoking Behavior: A Biological Perspective.

    Wickham, R J

    2015-09-01

    Mentholated cigarettes gained popularity in the 1950s and were often marketed as "healthy" cigarettes, attributable to their pleasurable mint flavor and cooling sensation in the mouth, lungs, and throat. While it is clear that nicotine is the primary psychoactive component in tobacco cigarettes, recent work has suggested that menthol may also play a role in exacerbating smoking behavior, despite original health claims. Recent evidence highlights four distinct biological mechanisms that can alter smoking behavior: 1) menthol acts to reduce the initially aversive experiences associated with tobacco smoking; 2) menthol can serve as a highly reinforcing sensory cue when associated with nicotine and promote smoking behavior; 3) menthol's actions on nicotinic acetylcholine receptors may change the reinforcing value of nicotine; and 4) menthol can alter nicotine metabolism, thus increasing nicotine bioavailability. The purpose of this review is to highlight and evaluate potential biological mechanisms by which menthol can alter smoking behavior. PMID:26339211

    Tobacco use is dramatically increasing among youth. Growing attention has been addressed towards possible predictors of smoking in such a population. We evaluated a sample of Italian adolescents to verify whether adults and peers might influence their smoking status. Cross-sectional study was conducted in 16 schools of North Italy. Data were collected from 2001 to 2010 by means of a self-administered questionnaire on sociodemographic data and individual/social possible predictors of smoking. 2,444 students (56.7% boys; 43.3% girls; mean = 14.32??1.384 years) were analysed. 607 (24.8%) were current smokers; 1,837 (75.2%) were nonsmokers. The presence of smokers in the family, seeing teachers who smoke, the influence of friends, and the feeling of inferiority were predictors of youth smoking as well as unawareness of nicotine dangerous action to health. Running the logistic multivariate analysis with all the variables listed above in the same model, the strongest predictors of smoking were as follows: being unaware that pipe/cigar is harmful to health as cigarettes; not knowing that passive smoking is harmful to the growth of children; having seen teachers smoking. The present findings help to identify the variables that might favour smoking in youth. Such variables should become the target of prevention programs. PMID:25969830

    Despite the importance of the tobacco smoke particulate matter in the lungs to the etiology of pulmonary disease in cigarette smokers, little is currently known about the spatial distribution of particle deposition or the persistence of the resulting deposits in humans, and no satisfactory technique currently exists to directly observe tobacco smoke condensate in airways. In this proof-of-principle work, hyperpolarized (hp) 83Kr MRI and NMR spectroscopy are introduced as probes for tobacco smoke deposition in porous media. A reduction in the hp-83Kr longitudinal (T1) relaxation of up to 95% under near-ambient humidity, pressure and temperature conditions was observed when the krypton gas was brought into contact with surfaces that had been exposed to cigarette smoke. This smoke-induced acceleration of the 83Kr self-relaxation was observed for model glass surfaces that, in some experiments, were coated with bovine lung surfactant extract. However, a similar effect was not observed with hp-(129)Xe indicating that the 83Kr sensitivity to smoke deposition was not caused by paramagnetic species but rather by quadrupolar relaxation due to high adsorption affinity for the smoke deposits. The 83Kr T1 differences between smoke-treated and untreated surfaces were sufficient to produce a strong contrast in variable flip angle FLASH hp-83Kr MRI, suggesting that hp-83Kr may be a promising contrast agent for in vivo pulmonary MRI.

    The rate of smoking in Brazil is about 18.8%. Exposure to environmental tobacco smoke is one of the major factors predisposing children to several hazardous health problems. The objective of the present research was to analyze the effect of tobacco smoke exposure during childhood on cochlear physiology by measuring the transient evoked otoacoustic emissions (TEOAE) response levels. Cotinine, the main metabolite of nicotine, was measured in 145 students' (8-10 years old) urine. Sixty students indicated tobacco smoke exposure (TSE) (cotinine urine levels ? 5.0 ng/mL) and 85 did not. The evaluation of TEOAE of TSE students showed lower response levels, mainly on frequencies of 2.8 kHz on the right and left ears and 2.0 kHz on left ear and lower signal noise response levels, mainly on the 1.0 kHz and 1.4 kHz frequencies, when compared to controls that were not exposed to tobacco. The mean reduction observed in TEOAE of tobacco smoke exposure children was 2.1 dB SPL. These results have important implications on the damage to the cochlear structures and indicate a possible loss in hearing and hearing ability development. PMID:24284348

    Background Given the increasing evidence of its negative health effects, including contributions to both infectious and chronic diseases, waterpipe tobacco smoking raises public health concerns beyond even those presented by traditional smoking. Methods Identification of Clean Indoor Air Acts (CIAAs) from each of the 50 United States and District of Columbia were retrieved and examined for inclusion of regulatory measures where waterpipe tobacco smoking is concerned. Several instances of exemption to current CIAAs policies were identified. The cumulative policy lens is presented in this study. Results States vary in their inclusion of explicit wording regarding CIAAs to the point where waterpipe tobacco smoking, unlike traditional smoking products, is excluded from some legislation, thereby limiting authorities’ ability to carry out enforcement. Conclusion Consistent, comprehensive, and unambiguous legislative language is necessary to prevent establishments where waterpipe tobacco smoking occurs from skirting legislation and other forms of regulatory control. Stricter laws are needed due to the increasing negative health impact on both the smoker and the bystander. Actions at both the federal and state levels may be needed to control health risks, particularly among youth and young adult populations. PMID:26346473

    Objectives. We examined whether state tobacco control programs are effective in reducing the prevalence of adult smoking. Methods. We used state survey data on smoking from 1985 to 2003 in a quasi-experimental design to examine the association between cumulative state antitobacco program expenditures and changes in adult smoking prevalence, after we controlled for confounding. Results. From 1985 to 2003, national adult smoking prevalence declined from 29.5% to 18.6% (P<.001). Increases in state per capita tobacco control program expenditures were independently associated with declines in prevalence. Program expenditures were more effective in reducing smoking prevalence among adults aged 25 or older than for adults aged 18 to 24 years, whereas cigarette prices had a stronger effect on adults aged 18 to 24 years. If, starting in 1995, all states had funded their tobacco control programs at the minimum or optimal levels recommended by the Centers for Disease Control and Prevention, there would have been 2.2 million to 7.1 million fewer smokers by 2003. Conclusions. State tobacco control program expenditures are independently associated with overall reductions in adult smoking prevalence. PMID:18172148

    Background Studies have shown that cigarette smoking is associated with sleep disorders in the general population. But studies examining the association between smokeless tobacco use, secondhand smoke exposure and insufficient rest/sleep are limited. Methods We examined the association between smoking, smokeless tobacco use (n=83,072), secondhand smoke exposure (n=28,557) and insufficient rest/sleep among adults aged ?20 years in the state-based 2008 Behavioral Risk Factor Surveillance System. Exposure to secondhand smoke was defined as >1 day of exposure to cigarette smoking either at home or in the workplace in the preceding 7 days. Insufficient rest/sleep was defined as not getting enough rest/sleep everyday in the preceding 30 days. Results Compared to never smokeless tobacco users, the odds ratio (OR; 95% confidence interval [CI]) of insufficient rest/sleep was 1.16 (1.001.36) and 1.74 (1.372.22) among former and current users. Compared to non-smokers/non-smokeless tobacco users, the OR (95% CI) of insufficient rest/sleep for those who were both current smokers and current smokeless tobacco users was 2.21 (1.662.94). Regarding secondhand smoke exposure among non-smokers, those with second-hand smoke exposure had higher odds for insufficient rest/sleep than those without. In contrast, the odds of insufficient rest/sleep were similar among current smokers with or without secondhand smoke exposure. Conclusions In a multiethnic sample of US adults, compared to non-smokers/non-smokeless tobacco users, those who were both current smokers and current smokeless tobacco users had twice the odds of insufficient sleep. Secondhand smoke exposure was associated with insufficient rest/sleep among non-smokers. PMID:21144798

  8. The contribution of low tar cigarettes to environmental tobacco smoke

    1989-05-01

    A series of low tar cigarettes (LTC) were smoked and the quantities of condensable mainstream (inhaled) and sidestream (between puffs) smoke compounds were determined and compared to those produced by a high tar, nonfilter cigarette. It was found that the LTC produced large quantities of sidestream smoke condensates, about equal to the high tar cigarette, and contained very high levels of toxic or cocarcinogenic phenols. On an equal weight basis, the LTC emitted more of these hazardous compounds into sidestream and environmental tobacco smoke. Higher smoke yields of a flavor additive and a sugar degradation product indicated addition of such compounds during the manufacture of LTC. It was concluded that, compared to a high tar cigarette, smoking LTC may be better for the smoker, but not for the nearby nonsmoker. Information should be developed to allow smokers to choose LTC that produce lower levels of hazardous compounds in their environmentally emitted sidestream smoke.

  9. Formation and general characteristics of environmental tobacco smoke

    Guerin, M.R.

    1988-01-01

    The primary source of environmental tobacco smoke is the the smoke released directly from the tips of cigarettes between puffs; the sidestream smoke. Sidestream smoke is formed under different conditions than is mainstream smoke. It is enriched in alkaline constituents, contains greater quantities of vapor phase water, exhibits a smaller particle size, and is less affected by smoking conditions and cigarette design. Upon dilution in ambient air, particle size decreases due to evaporation thus redistributing many constituents from the particle phase to the vapor phase. Commonly found concentrations of ETS particulates matter, nicotine, and carbon monoxide in indoor environments are 50-200 ..mu..g/m/sup 3/, 2-20 ..mu..g/m/sup 3/, and 2-6 ppM, respectively. Physical composition and chemical concentration vary both spatially and temporally as determined in large part by smoking severity and degree of ventilation. 22 refs., 4 tabs.

    Waterpipe tobacco smoking (WTS) is an emerging tobacco product globally, especially among adolescents and young adults who may perceive WTS as a safe alternative to smoking cigarettes. Monitoring the use of WTS in Turkey in relation to the tobacco control policy context is important to ensure that WTS does not become a major public health issue in Turkey. The Global Adult Tobacco Survey (GATS) was conducted in Turkey in 2008 and was repeated in 2012. GATS provided prevalence estimates on current WTS and change over time. Other indicators of WTS were also obtained, such as age of initiation and location of use. Among persons aged 15 and older in Turkey, the current prevalence of WTS decreased from 2.3% in 2008 to 0.8% in 2012, representing a 65% relative decline. Among males, WTS decreased from 4.0% to 1.1% (72% relative decline). While the overall smoking prevalence decreased among females, there was no change in the rate of WTS (0.7% in 2008 vs. 0.5% in 2012), though the WTS prevalence rate was already low in 2008. Comprehensive tobacco control efforts have been successful in reducing the overall smoking prevalence in Turkey, which includes the reduction of cigarette smoking and WTS. However, it is important to continue monitoring the use of waterpipes in Turkey and targeting tobacco control efforts to certain groups that may be vulnerable to future WTS marketing (e.g., youth, women).

    This manuscript examines the public policy importance of 1993, United States Department of Health and Human Services actions to require doctors and hospitals to report a new external cause of injury code or E-code for environmental tobacco smoke related to causes of death such as lung cancer and severe heart disease. Methods included a qualitative archival analysis of all previously internal tobacco industry documents, pertinent newspaper and magazine articles, Americans for Nonsmokers' Rights database, and pertinent websites regarding environmental tobacco smoke and E-codes from 1993 to 1998. The E-code has continued to the present because of scientific and administrative recognition that environmental tobacco smoke is conclusively linked to illness and death. The industry argued that the E-code was unnecessary because of costs to business and no conclusive scientific evidence linking environmental tobacco smoke with pulmonary and cardiovascular deaths. This regulatory action based on current scientific evidence and medical decision-making contradicts the industry's claim that no deaths are conclusively associated with environmental tobacco smoke.

    Background Since the political transition in 1991, Russia has been targeted intensively by the transnational tobacco industry. Already high smoking rates among men have increased further; traditionally low rates among women have more than doubled. The tobacco companies have so far faced little opposition as they shape the discourse on smoking in Russia. This paper asks what ordinary Russians really think about possible actions to reduce smoking. Methods A representative sample of the Russian population (1600 respondents) was interviewed face-to-face in November 2007. Results Only 14% of respondents considered tobacco control in Russia adequate, while 37% felt that nothing was being done at all. There was support for prices keeping pace with or even exceeding inflation. Over 70% of all respondents favoured a ban on sales from street kiosks, while 56% believed that existing health warnings (currently 4% of front and back of packs) were inadequate. The current policy of designating a few tables in bars and restaurants as non-smoking was supported by less than 10% of respondents, while almost a third supported a total ban, with 44% supporting provision of equal space for smokers and non-smokers. Older age, non-smoking status and living a smaller town all emerged as significantly associated with the propensity to support of antismoking measures. The tobacco companies were generally viewed as behaving like most other companies in Russia, with three-quarters believing that they definitely or maybe bribe politicians. Knowledge of impact of smoking on health was limited with significant underestimation of dangers and addictive qualities of tobacco. A third believed that light cigarettes are safer than normal. Conclusion The majority of the Russian population would support considerable strengthening of tobacco control policies but there is also a need for effective public education campaigns.

    Objective (1) To review how current global tobacco control policies address regulation of waterpipe tobacco smoking (WTS). (2) To identify features associated with enactment and enforcement of WTS legislation. Data Sources (1) Legislations compiled by Tobacco Control Laws (www.tobaccocontrollaws.org). (2) Weekly news articles by ‘Google Alerts’ (www.google.com/alerts) from July 2013 to August 2014. Study Selection (1) Countries containing legislative reviews, written by legal experts, were included. Countries prohibiting tobacco sales were excluded. (2) News articles discussing aspects of the WHO FCTC were included. News articles related to electronic-waterpipe, crime, smuggling, opinion pieces or brief mentions of WTS were excluded. Data Abstraction (1) Two reviewers independently abstracted the definition of “tobacco product” and/or “smoking”. Four tobacco control domains (smokefree law, misleading descriptors, health warning labels and advertising/promotion/sponsorship) were assigned one of four categories based on the degree to which WTS had specific legislation. (2) Two investigators independently assigned at least one theme and associated subtheme to each news article. Data Synthesis (1) Reviewed legislations of 62 countries showed that most do not address WTS regulation but instead rely on generic tobacco/smoking definitions to cover all tobacco products. Where WTS was specifically addressed, no additional legislative guidance accounted for the unique way it is smoked, except for in one country specifying health warnings on waterpipe apparatuses (2) News articles mainly reported on noncompliance with public smoking bans, especially in India, Pakistan and the UK. Conclusions A regulatory framework evaluated for effectiveness and tailored for the specificities of WTS needs to be developed. PMID:25550418

    The multinational tobacco companies responded to arguments about the social costs of smoking and hazards of secondhand smoke by quietly implementing the Social Costs/Social Values project (1979–1989), which relied upon the knowledge and authoritative power of social scientists to construct an alternate cultural repertoire of smoking. Social scientists created and disseminated non-health based, pro-tobacco arguments without fully acknowledging their relationship with the industry. After the U.S. Surgeon General concluded that nicotine was addictive in 1988, the industry responded by forming “Associates for Research in the Science of Enjoyment” (c.1988–1999), whose members toured the world promoting the health benefits of the use of legal substances, including tobacco, for stress relief and relaxation, without acknowledging the industry’s role. In this paper we draw on previously secret tobacco industry documents, now available on the internet to show how both of these programs utilized academic sociologists, political scientists, anthropologists, psychologists, philosophers and economists, and allowed the industry to develop and widely disseminate friendly research through credible channels. Strategies included creating favorable surveys and opinions, infusing them into the lay press and media through press releases, articles and conferences, publishing, promoting and disseminating books, commissioning and placing favorable book reviews, providing media training for book authors and organizing media tours. These programs allowed the tobacco industry to affect public and academic discourse on the social acceptability of smoking. PMID:18164524

    Background Exposure to environmental tobacco smoke is a major threat to public health. Greece, having the highest smoking prevalence in the European Union is seriously affected by passive smoking. The purpose of this study was to measure environmental tobacco smoke (ETS) exposure in the non smoking areas of hospitality venues and offices in Greece and to compare the levels of exposure to levels in the US, UK and Ireland before and after the implementation of a smoking ban. Methods Experimental measurements of particulate matter 2.5 ?m (PM2.5), performed during a cross sectional study of 49 hospitality venues and offices in Athens and Crete, Greece during February March 2006. Results Levels of ETS ranged from 19 ?g/m3 to 612 ?g/m3, differing according to the place of measurement. The average exposure in hospitality venues was 268 ?g/m3 with ETS levels found to be highest in restaurants with a mean value of 298 ?g/m3 followed by bars and cafes with 271 ?g/m3. ETS levels were 76% lower in venues in which smoking was not observed compared to all other venues (p < 0.001). ETS levels in Greek designated non-smoking areas are similar to those found in the smoking sections of UK hospitality venues while levels in Ireland with a total smoking ban are 89% lower and smoke-free communities in the US are 91 96% lower than levels in Greece. Conclusion Designated non-smoking areas of hospitality venues in Greece are significantly more polluted with ETS than outdoor air and similar venues in Europe and the United States. The implementation of a total indoor smoking ban in hospitality venues has been shown to have a positive effect on workers and patrons' health. The necessity of such legislation in Greece is thus warranted. PMID:17956612

    Environmental determinants including aerosolized pollutants such as polycyclic aromatic hydrocarbons (PAHs) and tobacco smoke have been associated with exacerbation and increased incidence of asthma. The influence of aerosolized pollutants on the development of immune dysfunction in asthmatics has been suggested to be mediated through epigenetic remodeling. Genome accessibility and transcription are regulated primarily through DNA methylation, histone modification, and microRNA transcript silencing. Epigenetic remodeling has been shown in studies to be associated with Th2 polarization and associated cytokine and chemokine regulation in the development of asthma. This review will present evidence for the contribution of the aerosolized pollutants PAH and environmental tobacco smoke to epigenetic remodeling in asthma. PMID:24760221

    Results show that tobacco smoking is a widespread phenomenon among Senegalese adolescents for several important reasons: economic (the intensive advertisement campaigns in favor of tobacco smoking), cultural (the ambivalence of traditional attitudes of Western urbanization, and the attractiveness of the Western way of life), psychological (the traumas of modernism on a basically poor developing country). Despite this alarming picture, signs point to an effective preventive strategy aimed mainly at schoolgoing adolescents and based on joint legal, scientific, cultural, and even religious action.

    Eight tests investigating the function of circulating polymorphonuclear leukocytes were performed in 68 subjects, half of whom smoked at least 20 cigarettes per day. Comparison of the two groups allowed determination of the in vivo effect of tobacco smoke on the nonspecific defense system of the body. Ingestion ability, oxygen consumption, and bactericidal activity were normal in smokers. Myeloperoxidase and neutrophil alkaline phosphatase activities also were unchanged. The nitroblue tetrazolium reduction and the serum lysozyme levels were slightly increased in smokers. The capillary tube random migration, though, was depressed, and intensive smoking further aggravated this change. It is suggested that tobacco smoke acts directly on one (or several) unidentified target site of polymorphonuclear leukocytes. This impairment, demonstrated in vivo, probably plays a role in the genesis of the bronchopulmonary diseases so frequent in heavy smokers. PMID:222675

    OBJECTIVE: To examine the association between maternal smoking and non-syndromic orofacial clefts in infants. METHODS: A meta-analysis of the association between maternal smoking during pregnancy was carried out using data from 24 case-control and cohort studies. FINDINGS: Consistent, moderate and statistically significant associations were found between maternal smoking and cleft lip, with or without cleft palate (relative risk 1.34, 95% confidence interval 1.25-1.44) and between maternal smoking and cleft palate (relative risk 1.22, 95% confidence interval 1.10-1.35). There was evidence of a modest dose-response effect for cleft lip with or without cleft palate. CONCLUSION: The evidence of an association between maternal tobacco smoking and orofacial clefts is strong enough to justify its use in anti-smoking campaigns. PMID:15112010

    According to the World Health Organization (WHO), tobacco-related disease is the single largest preventable cause of death in the world today, killing around 5.4 million people a year an average of one person every six seconds. The total number of death caused by tobacco consumption is higher than that of tuberculosis, HIV/AIDS and malaria combined. Unlike other communicable diseases, however, tobacco-related disease has a man-made consensus vector the tobacco companies that play an active role to promote tobacco consumption, which directly heightens the disease morbidity. Any public health policy designed to curb smoking behavior has to prepare for opposite lobbying actions from tobacco companies that undermine the effects of the health measures. Another unique nature of the tobacco epidemic is that it can be cured, not by medicines or vaccines, but on the concerted actions of government and civil society. Many countries with a history of tobacco control measures indeed experienced a reduction of tobacco consumption. As most of these governments launched a range of measures simultaneously, it is hard to quantify the relative merits of different control strategies that contributed to the drop in the number of smokers. These packages of strategies can come in different forms but with some common features. Political actions with government support, funding, and protection are crucial. Without these, antismoking efforts in any part of the world are unlikely to be successful. PMID:19440270

    The aim of this general review is to investigate the influence of active and passive smoking on the development of asthma in children and adults. Passive smoking during and after pregnancy facilitates the onset of childhood asthma and wheezing. In particular, smoking during pregnancy is associated with the occurrence of wheezing prior to the age of 4 years. In contrast, the results of studies on the relationship between parental smoking in the post-natal period and the onset of asthma or wheezing are discordant. Exposure to passive smoking during childhood facilitates the occurrence of asthma in adulthood. In adults and adolescents, active smoking appears to be a factor favoring the development of asthma. On the other hand, non-smoking adult subjects without history of asthma exposed to passive smoking have a risk of asthma. The pathophysiological mechanisms by which tobacco smoke is the cause of asthma are still poorly known. Smoking cessation is an essential component in the management of asthmatic subjects who smoke, facilitating the control of the disease. PMID:25765119

    Inhalation exposure of environmental tobacco smoke (ETS) particles may increase health risks, but only to the extent that the particles deposit in the respiratory tract. We describe a technique to predict regional lung deposition of environmental tobacco smoke particles. Interpretation of particle size distribution measurements after cigarette combustion by a smoking machine in a test room yields an effective emissions profile. An aerosol dynamics model is used to predict indoor particle concentrations resulting from a specified combination of smoking frequency and building factors. By utilizing a lung deposition model, the rate of ETS mass accumulation in human lungs is then determined as a function of particle size and lung airway generation. Considering emissions of sidestream smoke only, residential exposures of nonsmokers to ETS are predicted to cause rates of total respiratory tract particle deposition in the range of 0.4-0.7 {mu}g/day per kg of body weight for light smoking in a well-ventilated residence and 8-13 {mu}g/day per kg for moderately heavy smoking in a poorly ventilated residence. Emissions of sidestream plus mainstream smoke lead to predicted deposition rates about a factor of 4 higher. This technique should be useful for evaluating health risks and control techniques associated with exposure to ETS particles. 36 refs., 6 figs., 3 tabs.

    Introduction This study examined patterns of use of flavored tobacco products in a nationally generalizable sample of Canadian students in grades 9 through 12 after the implementation of a national ban on certain flavored tobacco products. Methods Data from the 2010–2011 Youth Smoking Survey, a nationally generalizable sample of Canadian students in grades 9 through 12 (n = 31,396), were used to examine tobacco product use. Logistic regression models were used to examine differences in use of flavored tobacco products (cigarettes, pipes, little cigars or cigarillos, cigars, roll-your-own cigarettes, bidis, smokeless tobacco, water pipes, and blunt wraps) by sociodemographic and regional characteristics. Results Approximately 52% of young tobacco users used flavored products in the previous 30 days. Flavored tobacco use varied by product type and ranged from 32% of cigarette smokers reporting menthol smoking to 70% of smokeless tobacco users reporting using flavored product in the previous 30 days. The percentage of last-30-day users who used flavored tobacco was significantly higher in Quebec than in Ontario and significantly higher among youths who received weekly spending money than among those who received no money. Conclusion More than half of tobacco users in grades 9 through 12 in Canada use flavored tobacco, despite a national ban on certain flavored tobacco products. PMID:24945240

    Considerations of how gender-related factors influence smoking first appeared over 20 years ago in the work of critical and feminist scholars. This scholarship highlighted the need to consider the social and cultural context of women's tobacco use and the relationships between smoking and gender inequity. Parallel research on men's smoking and masculinities has only recently emerged with some attention being given to gender influences on men's tobacco use. Since that time, a multidisciplinary literature addressing women and men's tobacco use has spanned the social, psychological and medical sciences. To incorporate these gender-related factors into tobacco reduction and cessation interventions, our research team identified the need to clarify the current theoretical and methodological interpretations of gender within the context of tobacco research. To address this need a scoping review of the published literature was conducted focussing on tobacco reduction and cessation from the perspective of three aspects of gender: gender roles, gender identities, and gender relations. Findings of the review indicate that there is a need for greater clarity on how researchers define and conceptualize gender and its significance for tobacco control. Patterns and anomalies in the literature are described to guide the future development of interventions that are gender-sensitive and gender-specific. Three principles for including gender-related factors in tobacco reduction and cessation interventions were identified: a) the need to build upon solid conceptualizations of gender, b) the importance of including components that comprehensively address gender-related influences, and c) the importance of promoting gender equity and healthy gender norms, roles and relations.

    Introduction Tobacco exposure has been linked with sinonasal pathology and may be associated with allergic sensitization. This study evaluates the association between exposure to active smoking or secondhand smoke (SHS) and the prevalence of rhinitis and allergic sensitization in the US adult population. Methods Cross-sectional study in 4,339 adults aged 2085 in the National Health and Nutrition Examination Survey, 20052006. Never smoking was defined as reported lifetime smoking less than 100 cigarettes and serum cotinine levels <10ng/ml, while active smoking was defined as self-reported smoking or serum cotinine concentrations > 10 ng/mL. Self-reported rhinitis was based on symptoms during the past 12 months, and allergen sensitization was defined as a positive response to any of the 19 specific IgE antigens tested. Results Almost half of the population (43%) had detectable levels of IgE specific to at least one inhaled allergen and 32% reported a history of rhinitis. After multivariate adjustment, there was a statistically significant association between the highest serum cotinine tertile and rhinitis in active smokers (OR 1.42; 95%CI 1.002.00). The association between active smoking and rhinitis was stronger in individuals without allergic sensitization (OR 2.47; 95%CI 1.444.23). There was a statistically significant association between increasing cotinine tertiles and decreased odds of inhaled allergen sensitization (p-trend <.01). Conclusion Tobacco smoke exposure was associated with increased prevalence of rhinitis symptoms, but not with allergic sensitization. The results indicate that the relationship between tobacco smoke exposure and sinonasal pathology in adults may be independent of allergic sensitization. PMID:26172447

    Objectives. Although US cigarette smoking is decreasing, hookah tobacco smoking (HTS) is an emerging trend associated with substantial toxicant exposure. We assessed how a representative sample of US tobacco control policies may apply to HTS. Methods. We examined municipal, county, and state legal texts applying to the 100 largest US cities. We developed a summary policy variable that distinguished among cities on the basis of how current tobacco control policies may apply to HTS and used multinomial logistic regression to determine associations between community-level sociodemographic variables and the policy outcome variable. Results. Although 73 of the 100 largest US cities have laws that disallow cigarette smoking in bars, 69 of these cities have exemptions that allow HTS; 4 of the 69 have passed legislation specifically exempting HTS, and 65 may permit HTS via generic tobacco retail establishment exemptions. Cities in which HTS may be exempted had denser populations than cities without clean air legislation. Conclusions. Although three fourths of the largest US cities disallow cigarette smoking in bars, nearly 90% of these cities may permit HTS via exemptions. Closing this gap in clean air regulation may significantly reduce exposure to HTS. PMID:22827447

    PURPOSE In studies of the fetal origins of disease and life course epidemiology, measures of fetal exposure may be based on information reported by the adults who were exposed in utero. In particular, the full spectrum of consequences of in utero exposure to maternal tobacco smoking is now an area of active investigation, and the ability to report such exposure reproducibly is of interest. We evaluated the reproducibility of in utero exposure to tobacco smoke, reported by the adult daughter during consecutive pregnancies. METHODS This study was based on 11,257 women who enrolled for more than one pregnancy in the Norwegian Mother and Child Cohort Study (MoBa). Participants completed a questionnaire around 17 weeks of gestation, which asked about their in utero exposure to tobacco smoke. Kappa statistics were calculated. Determinants of agreement were evaluated using logistic regression. RESULTS Weighted Kappa for in utero exposure for the first and second reports was 0.80. Determinants of agreement were higher education (better) and longer time between reports (worse). CONCLUSIONS Information on in utero exposure to maternal tobacco smoking provided by adult women was highly reproducible in this population. PMID:21130369

    According to World Health Organisation figures, 30% of all cancer deaths, 20% of all coronary heart diseases and strokes and 80% of all chronic obstructive pulmonary disease are caused by cigarette smoking. Environmental Tobacco Smoke (ETS) exposure has also been shown to be associated with disease and premature death in non-smokers. In response to this environmental health issue, several countries have brought about a smoking ban policy in public places and in the workplace. Countries such as the U.S., France, Italy, Ireland, Malta, the Netherlands, Sweden, Scotland, Spain, and England have all introduced policies aimed at reducing the population exposure to ETS. Several investigations have monitored the effectiveness of these smoking ban policies in terms of ETS concentrations, human health and smoking prevalence, while others have also investigated a number of alternatives to smoking ban policy measures. This paper reviews the state of the art in research, carried out in the field of ETS, smoking bans and Tobacco Control to date and highlights the need for future research in the area. PMID:19440413

    In France, in 2010, tobacco induced 81% of deaths by lung cancer corresponding to about 28,000 deaths. Continued smoking after diagnosis has a significant impact on treatment. In patients with lung cancer, the benefits of smoking cessation are present at any stage of disease. For early stages, smoking cessation decreases postoperative morbidity, reduces the risk of second cancer and improves survival. Previous to surgery, smoking cessation of at least six to eight weeks or as soon as possible is recommended in order to reduce the risk of infectious complications. Tobacco could alter the metabolism of certain chemotherapies and targeted therapies, such as tyrosine kinase inhibitors of the EGF receptor, through an interaction with P450 cytochrome. Toxicity of radiations could be lower in patients with lung cancer who did not quit smoking before treatment. For patients treated by radio-chemotherapy, overall survival seems to be better in former smokers but no difference is observed in terms of recurrence-free survival. For advanced stages, smoking cessation enhances patients' quality of life. Smoking cessation should be considered as full part of lung cancer treatment whatever the stage of disease. PMID:25727658

    This sub-study of a randomized, controlled, forced-switching, open-label, parallel-group, clinical study compared environmental tobacco smoke (ETS) produced when 60 male and female adult smokers switched to a third-generation electrically heated cigarette smoking system (EHCSS), continued to smoke a conventional cigarette (CC), or stopped smoking (No-smoking). Concentrations of air constituents including respirable suspended particulate (RSP), carbon monoxide (CO), ammonia and total volatile organic compounds (TVOCs) and ETS markers including solanesol-related particulate matter (Sol-PM), ultraviolet absorbing particulate matter (UVPM), fluorescent particulate matter (FPM), nicotine and 3-ethenyl pyridine (3-EP) were measured in a ventilated, furnished conference room over a 2-h period on separate occasions for each smoking condition. When the EHCSS was used, concentrations of CO and most ETS markers were in the same range as during no-smoking. Concentrations of ammonia were reduced by 41% and concentrations of other selected constituents of ETS were reduced by 87-99% in the air of a room in which EHCSS cigarettes were smoked as compared to concentrations in the same room when conventional cigarettes were smoked. Switching from conventional cigarette smoking to the EHCSS resulted in substantial reductions in concentrations of several markers of environmental tobacco smoke. PMID:18639603

    Smoking, both by donors and by recipients, has a major impact on outcomes after organ transplantation. Recipients of smokers' organs are at greater risk of death (lungs hazard ratio [HR], 1.36; heart HR, 1.8; and liver HR, 1.25), extended intensive care stays, and greater need for ventilation. Kidney function is significantly worse at 1 year after transplantation in recipients of grafts from smokers compared with nonsmokers. Clinicians must balance the use of such higher-risk organs with the consequences on waiting list mortality if the donor pool is reduced further by exclusion of such donors. Smoking by kidney transplant recipients significantly increases the risk of cardiovascular events (29.2% vs. 15.4%), renal fibrosis, rejection, and malignancy (HR, 2.56). Furthermore, liver recipients who smoke have higher rates of hepatic artery thrombosis, biliary complications, and malignancy (13% vs. 2%). Heart recipients with a smoking history have increased risk of developing coronary atherosclerosis (21.2% vs. 12.3%), graft dysfunction, and loss after transplantation. Self-reporting of smoking is commonplace but unreliable, which limits its use as a tool for selection of transplant candidates. Despite effective counseling and pharmacotherapy, recidivism rates after transplantation remain high (10-40%). Transplant services need to be more proactive in educating and implementing effective smoking cessation strategies to reduce rates of recidivism and the posttransplantation complications associated with smoking. The adverse impact of smoking by the recipient supports the requirement for a 6-month period of abstinence in lung recipients and cessation before other solid organs. PMID:23169222

    Since aged and diluted smoke particles are in general smaller and more stable than mainstream tobacco smoke, it should be possible to model their deposition on the basis of their measured particle diameters. However in practice, measured deposition values are consistently greater than those predicted by deposition models. Thus the primary objective of this study was to compare theoretical predictions obtained by the Monte Carlo code IDEAL with two human deposition studies to attempt to reconcile these differences. In the first study, male and female volunteers inhaled aged and diluted sidestream tobacco smoke at two steady-state concentrations under normal tidal breathing conditions. In the second study, male volunteers inhaled aged and diluted sidestream smoke labelled with 212Pb to fixed inhalation patterns. Median particle diameters in the two studies were 125 nm (CMD) and 210 nm (AMD), respectively. Experimental data on total deposition were consistently higher than the corresponding theoretical predictions, exhibiting significant inter-subject variations. However, measured and calculated regional deposition data are quite similar to each other, except for the extra-thoracic region. This discrepancy suggests that either the initial particle diameter decreases upon inspiration and/or additional deposition mechanisms are operating in the case of tobacco smoke particles.

    Tobacco mainstream smoke (MSS) and sidestream smoke (SSS), butts, and ashes from commercial cigarettes and maleic hydrazide (MH) spiked cigarettes were analyzed for their MH contents. The MH transfer rates obtained for MSS ranged from 1.4% to 3.7%, for SSS ranged from 0.2% to 0.9%, and for butts ranged from 1.1% to 1.9%. And as expected, MH is absent in ashes. The transfer rate of MH into mainstream smoke is the top one during in transfer rate into main-stream, side-stream, ashes, and butts, and higher MH levels lead to more MH in smoke. Further, analysis of total MH in butts and ashes along with that in MSS and SSS indicates that much MH is destructed during the smoking process. PMID:23193377

    Objectives This study aims to provide data on a public level of support for restricting smoking in public places and banning tobacco advertisements. Design A nationally representative multistage sampling design, with sampling strata defined by region (sampling quotas proportional to size) and substrata defined by urban/rural and mountainous/lowland settlement, within which census enumeration districts were randomly sampled, within which households were randomly sampled, within which a randomly selected respondent was interviewed. Setting The country of Georgia, population 4.7 million, located in the Caucasus region of Eurasia. Participants One household member aged between 13 and 70 was selected as interviewee. In households with more than one age-eligible person, selection was carried out at random. Of 1588 persons selected, 14 refused to participate and interviews were conducted with 915 women and 659 men. Outcome measures Respondents were interviewed about their level of agreement with eight possible smoking restrictions/bans, used to calculate a single dichotomous (agree/do not agree) opinion indicator. The level of agreement with restrictions was analysed in bivariate and multivariate analyses by age, gender, education, income and tobacco use status. Results Overall, 84.9% of respondents indicated support for smoking restrictions and tobacco advertisement bans. In all demographic segments, including tobacco users, the majority of respondents indicated agreement with restrictions, ranging from a low of 51% in the 1325 age group to a high of 98% in the 5670 age group. Logistic regression with all demographic variables entered showed that agreement with restrictions was higher with age, and was significantly higher among never smokers as compared to daily smokers. Conclusions Georgian public opinion is normatively supportive of more stringent tobacco-control measures in the form of smoking restrictions and tobacco advertisement bans. PMID:24282242

    Withdrawal-based theories of addiction hypothesize that motivation to reinstate drug use following acute abstinence is mediated by withdrawal symptoms. Experimental tests of this hypothesis in the tobacco literature are scant and may be subject to methodological limitations. This study utilized a robust within-subject laboratory experimental design to investigate the extent to which composite tobacco withdrawal symptomatology level and three unique withdrawal components (i.e., low positive affect, negative affect, and urge to smoke) mediated the effect of smoking abstinence on motivation to reinstate smoking. Smokers (10≥cig/day; N=286) attended two counterbalanced sessions at which abstinence duration was differentially manipulated (1-hour vs. 17-hours). At both sessions, participants reported current withdrawal symptoms and subsequently completed a task in which they were monetarily rewarded proportional to the length of time they delayed initiating smoking, with shorter latency reflecting stronger motivation to reinstate smoking. Abstinence reduced latency to smoking initiation and positive affect and increased composite withdrawal symptom level, urge, and negative affect. Abstinence-induced reductions in latency to initiating smoking were mediated by each withdrawal component, with stronger effects operating through urge. Combined analyses suggested that urge, negative affect, and low positive affect operate through empirically-unique mediational pathways. Secondary analyses suggested similar effects on smoking quantity, few differences among specific urge and affect subtypes, and that dependence amplifies some abstinence effects. This study provides the first experimental evidence that within-person variation in abstinence impacts motivation to reinstate drug use through withdrawal. Urge, negative affect, and low positive affect may reflect unique withdrawal-mediated mechanisms underlying tobacco addiction. PMID:25961814

    Tobacco smoking is a well-known cause of various diseases, however, its toxic mechanisms for diseases are not completely understood, yet. Therefore, we performed biological monitoring to find tobacco smoking-responsive mechanisms including oxidative stress in Korean men (N=36). Whole genome microarray analyses were performed with peripheral blood from smokers and age-matched nonsmokers. We also performed qRT-PCR to confirm the microarray results and compared the gene expression of blood to those of buccal cells. To assess the effects of tobacco smoking on oxidative stress, we analyzed urinary levels of malondialdehyde (MDA), a lipid peroxidation marker, and performed PCR-based arrays on reactive oxygen species (ROS)-related genes. As results, 34 genes were differently expressed in blood between smokers and nonsmokers (ps<0.01 and >1.5-fold change). Particularly, the genes involved in immune responsive pathways, e.g., the Fcγ-receptor mediated phagocytosis and the leukocyte transendothelial migration pathways, were differentially expressed between smokers and nonsmokers. Among the above genes, the ACTG1, involved in the maintenance of actin cytoskeleton, cell migration and cancer metastasis, was highly expressed by smoking in both blood and buccal cells. Concerning oxidative stress, smokers showed high levels of urinary MDA and down-regulation of expressions of antioxidant related genes including TPO, MPO, GPX2, PTGR1, and NUDT1 as compared to nonsmokers (ps<0.05). In conclusion, these results suggest that systemically altered immune response and oxidative stress can be tobacco-responsive mechanisms for the related diseases. Based on consistent results in blood and buccal cells, expression of the ACTG1 can be a tobacco smoking-responsive biomarker. PMID:25447457

    Colorectal cancer is not strictly considered a tobacco-related malignancy, but modest associations have emerged from large meta-analyses. Most studies, however, use self-reported data, which are subject to misclassification. Biomarkers of tobacco exposure may reduce misclassification and provide insight into metabolic variability that potentially influences carcinogenesis. Our aim was to identify metabolites that represent smoking habits and individual variation in tobacco metabolism, and investigate their association with colorectal cancer. In a nested case-control study of 255 colorectal cancers and 254 matched controls identified in the Prostate, Lung, Colorectal and Ovarian cancer screening trial, baseline serum was used to identify metabolites by ultra-high-performance liquid-phase chromatography and mass spectrometry, as well as gas chromatography with tandem mass spectrometry. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Self-reported current smoking was associated with serum cotinine, O-cresol sulfate and hydroxycotinine. Self-reported current smoking of any tobacco (OR = 1.90, 95% CI: 1.02–3.54) and current cigarette smoking (OR = 1.51, 95% CI: 0.75–3.04) were associated with elevated colorectal cancer risks, although the latter was not statistically significant. Individuals with detectable levels of hydroxycotinine had an increased colorectal cancer risk compared with those with undetectable levels (OR = 2.68, 95% CI: 1.33–5.40). Although those with detectable levels of cotinine had a suggestive elevated risk of this malignancy (OR = 1.81, 95% CI: 0.98–3.33), those with detectable levels of O-cresol sulfate did not (OR = 1.16, 95% CI: 0.57–2.37). Biomarkers capturing smoking behavior and metabolic variation exhibit stronger associations with colorectal cancer than self-report, providing additional evidence for a role for tobacco in this malignancy.

    Tobacco use and second-hand smoke exposure during pregnancy are linked to a host of deleterious effects on the pregnancy, fetus, and infant. Health outcomes improve when women quit smoking at any time during the pregnancy. However, the developing heart is vulnerable to noxious stimuli in the early weeks of fetal development, a time when many women are not aware of being pregnant. Congenital heart defects are the most common birth defects. Research shows an association between maternal tobacco exposure, both active and passive, and congenital heart defects. This article presents recent evidence supporting the association between intrauterine cigarette smoke exposure in the periconceptional period and congenital heart defects and discusses clinical implications for practice for perinatal and neonatal nurses.

    Objective To examine the prevalence and potential health risks of waterpipe tobacco smoking. Methods A literature review was performed to compile information relating to waterpipe tobacco smoking. Results Waterpipe tobacco smoking is increasing in prevalence worldwide; in the United States, 1020% of some young adult populations are current waterpipe users. Depending on the toxicant measured, a single waterpipe session produces the equivalent of at least 1 and as many as 50 cigarettes. Misconceptions about waterpipe smoke content may lead users to underestimate health risks. Conclusion Inclusion of waterpipe tobacco smoking in tobacco control activities may help reduce its spread.

    The aim of this study was to evaluate the prevalence, behavioural patterns, and determinants of smoking among a large sample of high-school students from Porto, the second largest city in Portugal, information on sociodemographic characteristics and personal history of tobacco, alcohol, coffee, and illicit drug use was obtained from 2974 students, aged 12-19 years (48.7% female, 51.3% male), using an anonymous self-administered questionnaire. Crude and adjusted odds ratios (OR) were calculated by logistic regression analysis to estimate the association between smoking and the characteristics evaluated. Overall, 35.8% students had never smoked, 39.4% had tried it ("experimental" smokers) but were not smokers, 3.3% were former smokers, 6.6% occasional smokers, and 14.9% regular smokers. The mean age for starting smoking was 13.4 +/- 2.1 years for males and 13.4 +/- 1.6 years for females. The prevalence of current smoking was higher among males than females, but the difference was not significant. Male students were significantly more likely to smoke more cigarettes per day than were females. The prevalence of smoking was significantly associated with the following variables: being aged > 12 years; having parents who had attended school for < 4 years; having a mother (OR = 1.88), siblings (OR = 1.96) or friends (OR = 1.75) who smoked; low academic performance (OR = 1.74 for one or two failures and OR = 2.27 for more than two failures at school); and consumption of coffee (OR = 2.90), alcohol (OR = 3.53), or illicit drugs (OR = 6.69). The prevalence of smoking among adolescents increased with age. There is therefore a need for school-based tobacco prevention programmes which also deal with family influences on smoking.

    Objective: To determine quantitatively the extent of exposure of hospitality workers to environmental tobacco smoke (ETS) exposure during the course of a work shift, and to relate these results to the customer smoking policy of the workplace. Subjects: Three categories of non-smoking workers were recruited: (1) staff from hospitality premises (bars and restaurants) that permitted smoking by customers; (2) staff from smokefree hospitality premises; and (3) government employees in smokefree workplaces. All participants met with a member of the study team before they began work, and again at the end of their shift or work day. At each meeting, participants answered questions from a standardised questionnaire and supplied a saliva sample. Main outcome measures: Saliva samples were analysed for cotinine. The difference between the first and second saliva sample cotinine concentrations indicated the degree of exposure to ETS over the course of the work shift. Results: Hospitality workers in premises allowing smoking by customers had significantly greater increases in cotinine than workers in smokefree premises. Workers in hospitality premises with no restrictions on customer smoking were more highly exposed to ETS than workers in premises permitting smoking only in designated areas. Conclusions: Overall, there was a clear association between within-shift cotinine concentration change and smoking policy. Workers in premises permitting customer smoking reported a higher prevalence of respiratory and irritation symptoms than workers in smokefree workplaces. Concentrations of salivary cotinine found in exposed workers in this study have been associated with substantial involuntary risks for cancer and heart disease. PMID:12035005

    Background The initial evaluations of the introduction of legislation that regulates smoking in enclosed public places in European countries, describe an important effect in the control of exposure to environmental tobacco smoke. However, the evidence is still limited. The objective of this study is to estimate the short-term effects of the comprehensive "Tobacco control law" introduced in Spain on January 2006, which includes a total ban of smoking in workplaces and a partial limitation of smoking in bars and restaurants. Methods Cross-sectional, population-based study. The self-reported exposure to environmental tobacco smoke at home, at work, in bars and restaurants of the population aged 18 to 64 years in the Madrid Region during a period prior to the law (October and November 2005; n = 1750) was compared to that of the period immediately after the law came into force (January-July 2006; n = 1252). Adjusted odds ratios (OR) were calculated using logistic regression models. Results Passive exposure to tobacco smoke at home has hardly changed. However, at indoor workplaces there has been a considerable reduction: after the law came into force the OR for daily exposure > 0–3 hours versus non-exposure was 0.11 (95% CI: 0.07 to 0.17) and for more than 3 hours, 0.12 (95% CI: 0.09 to 0.18). For fairly high exposure in bars and restaurants versus non-exposure, the OR in the former was 0.30 (95% CI: 0.20 to 0.44) and in the latter was 0.24 (95% CI: 0.18 to 0.32); for very high exposure versus non-exposure they were 0.16 (95% CI: 0.10 to 0.24) and 0.11 (95% CI: 0.07 to 0.19), respectively. These results were similar for the smoking and non-smoking populations. Conclusion A considerable reduction in exposure to environmental tobacco smoke in the workplace and, to a lesser extent, in bars and restaurants, is related to the implementation of the "Tobacco control law". Although only initial figures, these results already demonstrate the effectiveness of strategies that establish control measures to guarantee smoke-free places. PMID:17760974

    Few studies have examined the smoking behaviors of problem gamblers. A high proportion of problem gamblers calling a gambling helpline reported daily tobacco smoking (43.1%). Problem gamblers reporting daily tobacco smoking more frequently acknowledged depression and suicidality secondary to gambling, gambling-related arrests, alcohol and drug use problems, mental health treatment, and problems with casino slot machine gambling. The findings substantiate the relationship in problem gamblers between tobacco smoking and psychiatric symptomatology, particularly other substance use problems. The high proportion of callers reporting daily tobacco smoking highlights the need for enhanced smoking cessation efforts in problem gamblers. PMID:15764425

    Active and passive smoking have been associated with an array of adverse effects on health. The development of valid and accurate scales of measurement for exposures associated with health risks constitutes an active area of research. Tobacco smoke exposure still lacks an ideal method of measurement. A valid estimation of the risks associated with tobacco exposure depends on accurate measurement. However, some groups of people are more reluctant than others to disclose their smoking status and exposure to tobacco. This is particularly true for pregnant women and parents of young children, whose smoking is often regarded as socially unacceptable. For others, recall of tobacco exposure may also prove difficult. Because relying on self-report and the various biases it introduces may lead to inaccurate measures of nicotine exposure, more objective solutions have been suggested. Biomarkers constitute the most commonly used objective method of ascertaining nicotine exposure. Of those available, cotinine has gained supremacy as the biomarker of choice. Traditionally, cotinine has been measured in blood, saliva, and urine. Cotinine collection and analysis from these sources has posed some difficulties, which have motivated the search for a more consistent and reliable source of this biomarker. Hair analysis is a novel, noninvasive technique used to detect the presence of drugs and metabolites in the hair shaft. Because cotinine accumulates in hair during hair growth, it is a unique measure of long-term, cumulative exposure to tobacco smoke. Although hair analysis of cotinine holds great promise, a detailed evaluation of its potential as a biomarker of nicotine exposure, is needed. No studies have been published that address this issue. Because the levels of cotinine in the body are dependent on nicotine metabolism, which in turn is affected by factors such as age and pregnancy, the characterization of hair cotinine should be population specific. This review aims at defining the sensitivity, specificity, and clinical utilization of different methods used to estimate exposure to cigarette smoking and environmental tobacco smoke. PMID:19125149

    The consumption of cigarettes in Papua New Guinea appears to have increased tenfold over the past twenty years, largely as a result of massive advertising campaigns. It is recommended that legislation be introduced to enforce restrictions on the levels of tar and nicotine in cigarettes sold here, and to make it compulsory to print health warnings on cigarette packets. It is also recommended that the advertising of tobacco products be restricted or banned. PMID:6951348

    The aim of this paper was to establish the frequency and intensity of smoking by the patients and hospital staff and to define the attitudes of the polled persons towards smoking tobacco on the premises of the hospital and their opinions about the limitations in force. The examination in the form of a distributed questionnaire, comprised 101 patients and 127 staff members of Henryk Klimontowicz Specialist Hospital in Gorlice (province of Ma?opolska /Little Poland/). Both mobile and bed-ridden patients participated in the study. The personnel was represented by physicians, nurses, ward attendants, psychologists, secretaries, Medical University students doing their apprenticeships on the premises of the hospital, employees of technical and administrative departments. The study was carried out by means of a diagnostic sounding with the use of a distributed questionnaire technique in the period from September 2002 to July 2003. The questionnaire contained 38 questions, including closed, open, half-open and multiple-choice questions. In our poll we used the Fagerstrom test, which determined the type of addiction to smoking tobacco (physical or psychological), and which was completed by tobacco-smokers. The statistical analysis was carried out by means of the Chi2 test for independence, assuming the significance level of 0.05. The obtained results were analyzed according to the sex of the polled persons and their functions in the premises of the hospital (patient, staff member). The results of the obtained analysis show that 13.9% of the polled patients of the Specialist Hospital in Gorlice smoked cigarettes every day. The percentage of everyday smokers among the staff of this hospital was significantly higher and equalled 18.1%. Half of the polled persons were exposed to passive smoking on the premises of the hospital, the staff more than the patients. The patients supported the restrictions concerning smoking on the premises of the hospital to a greater extent than the personnel. Most of the smokers claimed that they were trying to cut down on smoking on the premises of the hospital. Despite these declarations, tobacco-smokers smoked cigarettes in the area of the hospital anyway, and one fifth of the smokers smoked also outside the places designed for that purpose. PMID:16146043

    BACKGROUND: Data from a cancer screening project among pattern makers were used to evaluate the association between tobacco smoking and prevalence of colon polyps. METHODS: From 1981-1983, 549 White men were examined by flexible sigmoidoscopy and completed self-administered questionnaires including smoking histories. RESULTS: One or more colon polyps were detected in 76 men. Standardized prevalence rates (SPR) for polyps increased by smoking category (never smoked = 0.094; ex-smokers = 0.118, current smokers = 0.214) and by cigarettes per day, years of smoking, and pack-years among both current and ex-smokers. Both adenomatous and hyperplastic polyps showed an association with smoking while other types of polyps and polyps with unspecified histology did not. The risk associated with smoking was greater for polyps greater than one centimeter in diameter. An interaction with occupational exposures was suggested by a greater increase in the SPR for polyps among current smokers employed as pattern makers for more than 10 years than among current smokers similarly employed for 10 years or less. CONCLUSIONS: Since at least some colon polyps are considered precursor lesions to colon cancer, one of the most common cancers in the United States, this report suggests that the possible link between colon polyps and smoking deserves further evaluation.

    Introduction: Waterpipe tobacco smoking (WTS) is an increasingly prevalent form of tobacco use in the United States. Its appeal may stem from its social, ritualistic, and aesthetic nature. Our aim in this study was to understand WTS as a social ritual with the goal of informing prevention efforts. Methods: We conducted a covert observational study consisting of 38 observation sessions in 11 WTS establishments in 3 U.S. cities. Data collection was based on an established conceptual framework describing ritualistic elements of tobacco use. Iterative codebook development and qualitative thematic synthesis were used to analyze data. Results: Atmospheres ranged from quiet coffee shop to boisterous bar party environments. While some children and older adults were present, the majority of clientele were young adults. Men and women were evenly represented. However, there were 19 occurrences of a male smoking by himself, but no women smoked alone. The vast majority (94%) of the clientele were actively smoking waterpipes. All 83 observed groups manifested at least 1 of the ritual elements of our conceptual framework, while 41 of the 83 observed groups (49%) demonstrated all 4 ritual elements. Conclusions: Despite its heterogeneity, WTS is often characterized by 1 or more established elements of a tobacco-related social ritual. It may be valuable for clinical and public health interventions to acknowledge and address the ritualistic elements and social function of WTS. PMID:24972889

    Previous studies have associated youth's exposure to filmic images of smoking with real-life smoking acquisition; initial research in low- and middle-income countries confirms this relationship. The present study in Yunnan, southwest China sought answers to the following questions: How do young people in China make sense of smoking imagery they have seen in film? How are these perceptions shaped by the cultural and social context of images? How do these understandings relate to real-life tobacco use? A study with focus groups and grounded theory was conducted in 2010 and 2011 (Sept-Jan) with middle-school students ages 12 and 13 (n=68, focus groups=12, schools=6). Films and media literacy were important means through which knowledge about smoking was constructed and communicated. Film representations of smoking concurred with Chinese social behaviour (Confucian social networks, face-making, and the notion of society as a harmonious social unit), and were interpreted as congruent with real-life smoking. This pattern, in turn, was intertwined with perceived gender identities of smokers, gender-specific social behaviour, and willingness of girls to explore issues of gender equity. These findings lend new insights into interaction between smoking imagery in film and Chinese youth's smoking beliefs. Tobacco control programs in China should consider young people's interpretations of smoking and the ways they are nested in cultural and social milieu. PMID:22445156

    Objective Waterpipe tobacco smoking (WTS) involves passing tobacco smoke through water prior to inhalation, and has spread worldwide. This spread becomes a public health concern if it is associated with tobacco-caused disease and if WTS supports tobacco/nicotine dependence. A growing literature demonstrates that WTS is associated with disability, disease and death. This narrative review examines if WTS supports nicotine/tobacco dependence, and is intended to help guide tobacco control efforts worldwide. Data sources PUBMED search using: ((“waterpipe” or “narghile” or “arghile” or “shisha” or “goza” or “narkeela” or “hookah” or “hubble bubble”)) AND (“dependence” or “addiction”). Study selection Excluded were articles not in English, without original data, and that were not topic-related. Thirty-two articles were included with others identified by inspecting reference lists and other sources. Data synthesis WTS and the delivery of the dependence-producing drug nicotine were examined, and then the extent to which the articles addressed WTS-induced nicotine/dependence explicitly, as well as implicitly with reference to criteria for dependence outlined by the WHO. Conclusions WTS supports nicotine/tobacco dependence because it is associated with nicotine delivery, and because some smokers experience withdrawal when they abstain from waterpipe, alter their behaviour in order to access a waterpipe and have difficulty quitting, even when motivated to do so. There is a strong need to support research investigating measurement of WTS-induced tobacco dependence, to inform the public of the risks of WTS, which include dependence, disability, disease and death, and to include WTS in the same public health policies that address tobacco cigarettes.

    This study examined whether awareness of tobacco control policies was associated with social unacceptability of smoking and whether social unacceptability had an effect on smoking cessation in three European countries. Representative samples (n = 3865) of adult smokers in France, the Netherlands and Germany were used from two survey waves of the longitudinal International Tobacco Control Europe Surveys. Associations were examined of aspects of social unacceptability of smoking (i.e. feeling uncomfortable, important people disapproval and societal disapproval) with tobacco policy awareness (i.e. awareness of warning labels, anti-tobacco information and smoking restrictions at work) and smoking cessation. Only the positive association of awareness of anti-tobacco information with feeling uncomfortable about smoking was significant in each of the three countries. Important people disapproval predicted whether smokers attempted to quit, although this did not reach significance in the French and German samples in multivariate analyses. Our findings suggest that anti-tobacco information campaigns about the dangers of second-hand smoke in France and about smoking cessation in the Netherlands and Germany might have reduced the social acceptability of smoking in these countries. However, campaigns that influence the perceived disapproval of smoking by important people may be needed to ultimately increase attempts to quit smoking. PMID:23861478

    Maternal exposure to environmental tobacco smoke (ETS) is a major health hazard as it contains lower doses of the toxins that smokers' inhale. Prenatal exposure to wood fuel smoke has been linked to delivering low birth weight (LBW) infants. The study aims to assess the association between prenatal exposure to ETS and wood fuel smoke and LBW. A case-control study in ratio 1:1 was conducted in two hospitals with obstetric services in Gaza Strip. Subjects were selected during May-June and July-August 2007 from attenders of Mbarak Hospital and Shifa Medical Centre, respectively. 184 (41.2%), and 79 (17.7%) out of 446 participants were exposed to environmental tobacco smoke and wood fuel smoke, respectively. Adjusted maternal exposure to ETS (especially the number of cigarettes smoked, water pipe and wood fuel smoke) was associated with LBW infants. Cigarette smoke exhibits an independent dose-response risk of LBW after adjusting for confounders. Prenatal exposure to cigarette smoke indoors is related to a reduction in birth weight of infants of -237 g (95% CI: -415, -58) for pregnant women exposed to 1-20 cigarettes per day and -391 g (95% CI: -642, -140) for exposure to more than 20 cigarettes per day. Exposure to wood fuel smoke exhibits a reduction of infants' adjusted mean birth weight by -186 g (95% CI: -354, -19). Prenatal exposure to passive smoking and wood fuel smoke are independently associated with LBW. Both these factors are modifiable exposures that could possibly lead to a reduction of delivering LBW infants. PMID:21842400

    The indoor concentration of suspended particulate matter (SPM) was measured in 44 retrofitted and tight dwellings, which had electric cooking and were central heated and where the basic ventilation rate in median amounted 0.23 air changes per hour as measured with a tracer dilution method. The indoor concentration of SPM was in medium 230 ..mu..g/m/sup 3/ with a strong correlation to the tobacco consumption (r/sub s/ = 0.716), but with no correlation to the frequency of airing or the basic ventilation rate. Tobacco smoking seems to be the main indoor source of SPM in contemporary dwellings. The importance of these findings is underlined by epidemiologic studies on passive smoking and health. Air quality standards for the ambient air are based on certain risk groups such as infants, children, persons with chronic obstructive lung disorders, and indoor air standards should be based on the same concepts of health protection.

    Specialized analytical instrumentation for detailed analysis of nicotine, benz(alpha)pyrene, pyridine and benzene in tooth enamel and pulp of inveterate tobacco smokers is created. A Waters PPY-24 liquid chromatograph is equipped with Model M660 solvent programmer and a Model U6K sample injector is used. A Model 440 dual-wavelength detector is used to obtain absorbance ratios on dual-pen recorder. Our data show that concentration of tobacco smoke components in tooth cavity of inveterate tobacco smokers is different. The chisel tooth pulp contained considerably more nicotine and pyridine as compared with molars. The level of benzene does not change analyzed structures. The assumption of linearity between calculation of predicted retention times and concentration has been shown to be valid up to about 8,0% for all studied compounds. PMID:20157203

    OBJECTIVES: Cigarette smoking is a leading risk factor for periodontal disease. This cross-sectional study investigated the relation between environmental tobacco smoke (ETS) and periodontal disease in the United States. METHODS: Data were obtained from the Third National Health and Nutrition Examination Survey (1988-1994). The outcome was periodontal disease, defined as 1 or more periodontal sites with attachment loss of 3 mm or greater and a pocket depth of 4 mm or greater at the same site. Exposure to ETS at home and work was self-reported. The study analyzed 6611 persons 18 years and older who had never smoked cigarettes or used other forms of tobacco. RESULTS: Exposure to ETS at home only, work only, and both was reported by 18.0%, 10.7%, and 3.8% of the study population, respectively. The adjusted odds of having periodontal disease were 1.6 (95% confidence interval = 1.1, 2.2) times greater for persons exposed to ETS than for persons not exposed. CONCLUSIONS: Among persons in the United States who had never used tobacco, those exposed to ETS were more likely to have periodontal disease than were those not exposed to ETS. PMID:11211634

    Study objective: To review the tobacco industry's Asian environmental tobacco smoke (ETS) consultants programme, focusing on three key nations: China, Hong Kong, and Malaysia. Methods: Systematic keyword and opportunistic website searches of formerly private internal industry documents. Main results: The release of the 1986 US Surgeon General's report on second hand smoke provoked tobacco companies to prepare for a major threat to their industry. Asian programme activities included conducting national/international symposiums, consultant "road shows" and extensive lobbying and media activities. The industry exploited confounding factors said to be unique to Asian societies such as diet, culture and urban pollution to downplay the health risks of ETS. The industry consultants were said to be "...prepared to do the kinds of things they were recruited to do". Conclusions: The programme was successful in blurring the science on ETS and keeping the controversy alive both nationally and internationally. For the duration of the project, it also successfully dissuaded national policy makers from instituting comprehensive bans on smoking in public places. PMID:15564219

    Objectives To determine what the tobacco industry knew about menthol cigarettes and the initiation of smoking. Methods Based on Food and Drug Administration staff-supplied research questions we used a snowball sampling strategy to search the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) between February and April 2010. Of the approximately 11 million documents available in the LTDL, the iterative searches returned tens of thousands of results. Researchers reviewed 2634 documents and 128 were deemed relevant to one or more of the research questions. Results The documents show that menthol is added to cigarettes in part because it is known to be an attractive feature to inexperienced smokers who perceive menthol cigarettes as less harsh and easier to smoke and because of their availability from friends and family. Second, the tobacco industry found that some youths smoke menthols because they perceive them to be less harmful than non-menthol cigarettes. A key product design issue concerns whether to increase brand menthol levels to appeal to the taste preferences of long-term menthol smokers or keep menthol levels lower to appeal to inexperienced smokers. Marketing studies showed that the companies carefully researched the menthol segment of the market in order to recruit younger smokers to their brands. The industry tracked menthol cigarette usage by age, gender and race to inform product development and marketing decisions. Conclusions Menthol is a prominent design feature used by cigarette manufacturers to attract and retain new, younger smokers. PMID:21504927

    Despite the presence of tobacco control policies, Louisiana continues to experience a high smoking burden and elevated smoking-attributable deaths. The SimSmoke model provides projections of these health outcomes in the face of existing and expanded (simulated) tobacco control polices. The SimSmoke model utilizes population data, smoking rates, and various tobacco control policy measures from Louisiana to predict smoking prevalence and smoking-attributable deaths. The model begins in 1993 and estimates are projected through 2054. The model is validated against existing Louisiana smoking prevalence data. The most powerful individual policy measure for reducing smoking prevalence is cigarette excise tax. However, a comprehensive cessation treatment policy is predicted to save the most lives. A combination of tobacco control policies provides the greatest reduction in smoking prevalence and smoking-attributable deaths. The existing Louisiana excise tax ranks as one of the lowest in the country and the legislature is against further increases. Alternative policy measures aimed at lowering prevalence and attributable deaths are: cessation treatments, comprehensive smoke-free policies, and limiting youth access. These three policies have a substantial effect on smoking prevalence and attributable deaths and are likely to encounter more favor in the Louisiana legislature than increasing the state excise tax.

    2004-04-01

    The present review examines the current status of efforts to reduce environmental tobacco smoke exposure (ETS) among infants and young children. Estimates of the number of children exposed vary, but it is probably over 20 million or about 35% of all U.S. children. Healthy People 2010 sets as an objective the reduction, to 10%, of the proportion of children regularly exposed to tobacco smoke at home. Children with ETS exposure are at higher risk for upper respiratory illnesses, asthma, otitis media, and sudden infant death syndrome. Eight experimental or quasi-experimental studies of attempts to reduce children' ETS exposure with sample sizes of greater than 100 were conducted in the United States and published between 1990 and 2003. Most of these studies showed a significant impact on maternal smoking and on the number of cigarettes smoked in the home, although intervention-control differences were relatively small. Despite support from professional organizations and federal government groups, many pediatricians and family physicians do not routinely engage in intensive efforts to reduce children's ETS exposure. Training in techniques for reducing tobacco dependence should be included in professional education programs. Public and private insurance should reimburse providers for efforts in this area. An overall strategy for reducing children's ETS exposure should combine individual counseling and education in offices, clinics, and homes with community education and regulatory and economic policies (i.e., smoking bans and excise taxes). Additional funding is needed for studies of provider knowledge, attitudes, and practices; of the effectiveness of various communication strategies; and of office- and community-based strategies to reduce ETS exposure.

    Epidemiologic studies of companion animals such as dogs have been established as models for the relationship between exposure to environmental tobacco smoke (ETS) and cancer risk in humans. While results from these studies are provocative, pet owner report of a dog's ETS exposure has not yet been validated. We have evaluated the relationship between dog owner's report of household smoking by questionnaire and dog's urinary cotinine level. Between January and October 2005, dog owners presenting their pet for non-emergency veterinary care at the Foster Hospital for Small Animals at Cummings School of Veterinary Medicine, Tufts University, were asked to complete a 10-page questionnaire measuring exposure to household ETS in the previous 24 h and other factors. A free-catch urine sample was also collected from dogs. Urinary cotinine level was assayed for 63 dogs, including 30 whose owners reported household smoking and 33 unexposed dogs matched on age and month of enrollment. Urinary cotinine level was significantly higher in dogs exposed to household smoking in the 24 h before urine collection compared to unexposed dogs (14.6 ng/ml vs. 7.4 ng/ml; P=0.02). After adjustment for other factors, cotinine level increased linearly with number of cigarettes smoked by all household members (P=0.004). Other canine characteristics including age, body composition and nose length were also associated with cotinine level. Findings from our study suggest that household smoking levels as assessed by questionnaire are significantly associated with canine cotinine levels.

Methods Data were from the 2009–2010 National Adult Tobacco Survey, a nationally representative sample of U.S. adults. Estimates of WTS ever and current use were reported overall, and by sex, age, race/ethnicity, educational attainment, annual household income, sexual orientation, and cigarette smoking status. State-level prevalence rates of WTS ever were reported using choropleth thematic maps for the overall population and by sex. Results The national prevalence of WTS ever was 9.8% and 1.5% for current use. WTS ever was more prevalent among those who are male (13.4%), 18–24 years old (28.4%) compared to older adults, non-Hispanic White (9.8%) compared to non-Hispanic Black, with some college education (12.4%) compared to no high school diploma, and reporting sexual minority status (21.1%) compared to heterosexuals. States with highest prevalence included DC(17.3%), NV(15.8%), and CA(15.5%). Conclusion WTS is now common among young adults in the US and high in regions where cigarette smoking prevalence is lowest and smoke-free policies have a longer history. To reduce its use, WTS should be included in smoke-free regulations and state and federal regulators should consider policy development in other areas, including taxes, labeling, and distribution.

    The benefits of preventing smoking onset are well known, and even just delaying smoking onset conveys benefits. Tobacco control policies are of critical importance to low-income countries with high smoking rates such as Vietnam where smoking prevalence is greater than 55% in young men between the ages of 25 and 45. Using a survey of teens and young adults, I conducted duration analyses to explore the impact of tobacco price on smoking onset. The results suggest that tobacco prices in Vietnam have a statistically significant and fairly substantial effect on the onset of smoking. Increases in average tobacco prices, measured by an index of tobacco prices and by the prices of two popular brands, are found to delay smoking onset. Of particular interest is the finding that Vietnamese youth are more sensitive to changes in prices of a popular international brand that has had favourable tax treatment since the late 1990s.

    The purpose of this cross-sectional study in a stratified random sample of 135 bars and restaurants in North Dakota was to describe factors that influenced tobacco smoke pollution levels in the venues; to compare the quantity of tobacco smoke pollution by rurality and by presence of local ordinances; and to assess compliance with state and local laws. In data collection in 2012, we measured the indoor air quality indicator of particulate matter (2.5 microns aerodynamic diameter or smaller), calculated average smoking density and occupant density, and determined compliance with state and local smoking ordinances using observational methods. As rurality increased, tobacco smoke pollution in bars increased. A significant association was found between stringency of local laws and level of tobacco smoke pollution, but the strength of the association varied by venue type. Compliance was significantly lower in venues in communities without local ordinances. Controlling for venue type, 69.2% of smoke-free policy's impact on tobacco smoke pollution levels was mediated by observed smoking. This study advances scientific knowledge on the factors influencing tobacco smoke pollution and informs public health advocates and decision makers on policy needs, especially in rural areas.

    Background: This study examines the effect of past tobacco control policies and projects the effect of future policies on smoking and snus use prevalence and associated premature mortality in Sweden. Methods: The established SimSmoke model was adapted with population, smoking rates and tobacco control policy data from Sweden. SimSmoke evaluates the effect of taxes, smoke-free air, mass media, marketing bans, warning labels, cessation treatment and youth access policies on smoking and snus prevalence and the number of deaths attributable to smoking and snus use by gender from 2010 to 2040. Results: Sweden SimSmoke estimates that significant inroads to reducing smoking and snus prevalence and premature mortality can be achieved through tax increases, especially when combined with other policies. Smoking prevalence can be decreased by as much as 26% in the first few years, reaching a 37% reduction within 30 years. Without effective tobacco control policies, almost 54 500 lives will be lost in Sweden due to tobacco use by the year 2040. Conclusion: Besides presenting the benefits of a comprehensive tobacco control strategy, the model identifies gaps in surveillance and evaluation that can help better focus tobacco control policy in Sweden.

    The available epidemiological studies of lung cancer and exposure to other people's tobacco smoke, in which exposure was assessed by whether or not a person classified as a non-smoker lived with a smoker, were identified and the results combined. There were 10 case-control studies and three prospective studies. Overall, there was a highly significant 35% increase in the risk of lung cancer among non-smokers living with smokers compared with non-smokers living with non-smokers (relative risk 1.35, 95% confidence interval 1.19 to 1.54). Part of this increase was almost certainly caused by the misclassification of some smokers as non-smokers. As smokers, who are more likely to get lung cancer than non-smokers, tend to live with smokers this misclassification probably exaggerated the estimated increase in risk. Adjustment for this error reduced the estimate to 30% (relative risk 1.30), but as people who live with non-smokers may still be exposed to other people's smoke this estimate was revised again to allow for the fact that a truly unexposed reference group was not used. The increase in risk among non-smokers living with smokers compared with a completely unexposed group was thus estimated as 53% (relative risk of 1.53). This analysis, and the fact that non-smokers breathe environmental tobacco smoke, which contains carcinogens, into their lungs and that the generally accepted view is that there is no safe threshold for the effect of carcinogens, leads to the conclusion that breathing other people's tobacco smoke is a cause of lung cancer. About a third of the cases of lung cancer in non-smokers who live with smokers, and about a quarter of the cases in non-smokers in general, may be attributed to such exposure. PMID:3096439

    Particulate matter (PM) derived from tobacco smoke contains numerous toxic substances. Since the PM and gas phase of tobacco smoke may distribute differently in the environment, and substances in them may have different human bioavailability, multiple tracers and biomarkers for tobacco smoke constituents are desirable. Nicotelline is a relatively non-volatile alkaloid present in tobacco smoke, and therefore it has the potential to be a suitable tracer and biomarker for tobacco smoke-derived PM. We describe experiments demonstrating that nicotelline is present almost entirely in the PM, in both freshly generated cigarette smoke and aged cigarette smoke. An excellent correlation between the mass of nicotelline and the mass of the PM in aged cigarette smoke was found. We also describe experiments suggesting that the main source of nicotelline in tobacco smoke is dehydrogenation of another little-studied tobacco alkaloid, anatalline, during the burning process. We show that nicotelline metabolites can be measured in urine of smokers, and that nicotelline can be measured in house dust from homes of smokers and non-smokers. We conclude that nicotelline should be useful as a tracer and biomarker for PM derived from tobacco smoke. PMID:24125094

    Fine particulate matter samples were collected in an urban ambient fixed site and, outside and inside residencies in Athens greater area, Greece. n-Alkanes, iso/anteiso-alkanes and polycyclic aromatic hydrocarbons (PAHs) were identified by gas chromatography and mass spectrometry. The values of concentration diagnostic ratios indicated a mixture of vehicular emissions, fuel evaporation, oil residues and environmental tobacco smoke (ETS) in outdoor and indoor samples. Particulate iso/anteiso-alkanes, specific tracers of ETS, were detected in both non-smoking and smoking households. The indoor-to-outdoor ratios of particulate iso/anteiso-alkanes and unresolved complex mixture (a tracer of outdoor air pollution) in non-smoking households were comparable to the measured air exchange rate. This suggested that penetration of outdoor air was solely responsible for the detection of tobacco smoke particulate tracers in indoor non-smoking environments. Overall, residential outdoor concentrations accounted for a large fraction (from 25 up to 79%) of indoor aliphatic and polyaromatic hydrocarbons. Open windows/doors and the operation of an air condition unit yielded also in higher indoor concentrations than those measured outdoors.

    BACKGROUND AND OBJECTIVE: Tobacco during pregnancy affects the health of the newborn. The aim was to assess the effect of maternal exposure to active and passive tobacco and of smoking cessation on the risk of preterm deliveries and birth weight, taking into account other risk factors.PATIENTS AND METHOD: Longitudinal study conducted in 282 healthy pregnant women. General, obstetrical and hematological data were collected as it was the smoking habit during pregnancy. Pregnant women were classified as "exposed to smoke" (active smoker and passive smoker) and "unexposed to smoke" (non-smokers and women who quitted smoking during pregnancy).RESULTS: A percentage of 59.2 were non-smokers, 18.4% active smokers, 8.5% second-hand smokers and 13.8% had stopped smoking. Unexposed pregnant women who stopped smoking had the same risk of premature deliveries and children with similar birth weight as non-smoker women. Active and second-hand smokers were at higher risk of preterm deliveries than non-smokers (odds ratio [OR] 6.5, 95% confidence interval [95% CI] 1.4-30.8 and OR 6.2, 95% CI 1.0-38.9, respectively); however, higher levels of hemoglobin in the 1st and 3rd trimester exerted a protective effect (OR 0.9, 95% CI 0.8-0.9). Active and second-hand smokers had babies weighing less than non-smokers (around 129 and 178g less, respectively).CONCLUSIONS: Active or passive exposure to smoke during pregnancy and lower hemoglobin levels are associated with an increased risk of premature deliveries and lower birth weight. Stopping smoking during pregnancy prevents these detrimental effects.

    The purpose of this study was to explore individual- and school-level policy characteristics on student smoking behavior using an ecological perspective. Participants were 24,213 (51% female) Grade 10-11 students from 81 schools in five Canadian provinces. Data were collected using student self-report surveys, written policies collected from schools, interviews with school administrators, and school property observations to assess multiple dimensions of the school tobacco policy. The multi-level modeling results revealed that the school a student attended was associated with his/her smoking behavior. Individual-level variables that were associated with student smoking included lower school connectedness, a greater number of family and friends who smoked, higher perceptions of student smoking prevalence, lower perceptions of student smoking frequency, and stronger perceptions of the school tobacco context. School-level variables associated with student smoking included weaker policy intention indicating prohibition and assistance to overcome tobacco addiction, weaker policy implementation involving strategies for enforcement, and a higher number of students smoking on school property. These findings suggest that the school environment is important to tobacco control strategies, and that various policy dimensions have unique relationships to student smoking. School tobacco policies should be part of a comprehensive approach to adolescent tobacco use. PMID:19779813

    2011-01-01

    Introduction: Previous studies have indicated that high sensation seekers are more sensitive to the reinforcing effects of nicotine, initiate smoking at an earlier age, and smoke greater amounts of cigarettes. This study examined the influence of sensation-seeking status on tobacco smoking following deprivation in regular tobacco users. Methods: Twenty healthy tobacco-smoking volunteers with low or high impulsive sensation-seeking subscale scores completed 2 consecutive test days per week for 3 consecutive weeks. Each week, a range of self-report, performance, and cardiovascular assessments were completed during ad libitum smoking on Day 1 and before and after the paced smoking of a tobacco cigarette containing 0.05, 0.6, or 0.9 mg of nicotine following 24 hr of tobacco deprivation on Day 2. In addition, self-administration behavior was analyzed during a 2-hr free access period after the initial tobacco administration. Results: In high sensation seekers, tobacco smoking independent of nicotine yield ameliorated deprivation effects, whereas amelioration of deprivation effects was dependent on nicotine yield among low sensation seekers. However, this effect was limited to a small subset of measures. Subsequent cigarette self-administration increased in a nicotine-dependent manner for high sensation seekers only. Conclusions: Compared with low sensation seekers, high sensation seekers were more sensitive to the withdrawal relieving effects of nonnicotine components of smoking following 24 hr of deprivation on selective measures and more sensitive to nicotine yield during subsequent tobacco self-administration. These results are consistent with studies suggesting that factors driving tobacco dependence may vary as a function of sensation-seeking status. PMID:21690318

    Introduction Waterpipe tobacco smoking, also known as hookah and shisha, has surged in popularity among young people in the United States. Waterpipe is also increasingly becoming the first tobacco product that young people try. Given the limited access to and limited portability of waterpipes, waterpipe smokers who become more nicotine dependent over time may be more likely to turn to cigarettes. This study examined the relationship between waterpipe tobacco smoking and susceptibility to cigarette smoking among young adults in the United States. Methods Using data from the 2012–2013 National Adult Tobacco Survey, a nationally representative sample of US adults, we reported rates of current waterpipe smoking and susceptibility to cigarette smoking by demographic characteristics and by use of other tobacco products among survey participants aged 18 to 24 years. Multivariable logistic regression was used to examine the relationship between current waterpipe smoking and susceptibility to cigarette smoking, defined as the lack of a firm intention not to smoke soon or within the next year. Results Of 2,528 young adults who had never established cigarette smoking, 15.7% (n = 398) reported being waterpipe smokers (every day or some days [n = 97; 3.8%] or rarely [n = 301; 11.9%]); 44.2% (176/398) of waterpipe smokers reported being susceptible to cigarette smoking. Those who smoked waterpipe rarely were 2.3 times as susceptible to cigarette smoking as those who were not current waterpipe smokers (OR = 2.3; 95% CI, 1.6–3.4). Conclusion Current waterpipe smoking is associated with susceptibility to cigarette smoking among young adults in the United States. Longitudinal studies are needed to demonstrate causality between waterpipe smoking and initiation of cigarette smoking. PMID:26890407

    Objective: To describe and understand the relationship between the tobacco and gambling industries in connection to their collaborative efforts to prevent smoke-free casinos and gambling facilities and fight smoke-free policies generally. Methods: Analysis of tobacco industry documents available online (accessed between February and December 2003). Results: The tobacco industry has worked to convince the gambling industry to fight against smoke-free environments. Representatives of the gambling industry with ties to the tobacco industry oppose smoke-free workplaces by claiming that smoke-free environments hurt gambling revenue and by promoting ventilation as a solution to secondhand smoke. With help from the tobacco industry, the gambling industry has become a force at the American Society of Heating Refrigeration and Air Conditioning Engineers opposing smoke-free ventilation standards for the hospitality industry. Conclusion: Tobacco industry strategies to mobilise the gambling industry to oppose smoke-free environments are consistent with past strategies to co-opt the hospitality industry and with strategies to influence policy from behind the scenes. Tobacco control advocates need to be aware of the connections between the tobacco and gambling industries in relation to smoke-free environments and work to expose them to the public and to policy makers.

    Environmental tobacco smoke is of serious concern in ventilated spaces both for comfort because of its odor properties and for health reasons. Although it has not been demonstrated as the primary cause in complaints, it is frequently seen as a contributing factor. Recirculation of air with ETS, without filtration or air-washing, may in fact lead to complaints, although at an unknown frequency. Finally, the contributions of ETS to the sick building syndrome is documented, although its extent is currently unknown. PMID:2690384

    The health of populations in industrialized societies has been affected for many years by ambient air pollutants presenting a threat of chronic bronchitis and lung cancer. In the 1980s indoor pollutants received much needed investigation to assess their hazards to health. Exposure to environmental tobacco smoke and radon is now the subject of much research and concern. This review attempts to put some perspective on lung cancer that is attributable to lifetime exposure to airborne pollutants. The view is expressed that air pollution control authorities have played and are playing a major role in health improvement.

    Objective To determine associations between positive and negative attitudes and hookah tobacco smoking (HTS) outcomes among college students. Methods Among a random sample of University of Florida students (N=852), multivariable logistic regression models assessed independent associations between positive and negative attitudes toward HTS. Results Positive attitudes were associated with adjusted odds of 4.32 (95% CI=3.20, 5.82) for current HTS, while negative attitudes were associated with lower adjusted odds for current smoking HTS (AOR=0.64, 95% CI=0.53, 0.76). Positive attitudes were also associated with adjusted odds of 9.31 (95% CI=6.77, 12.80) for intention for future hookah use. Conclusion Positive attitudes toward HTS were more strongly associated with HTS outcomes compared to negative attitudes. It may be particularly valuable for future research and interventions to focus on decreasing positive attitudes towards HTS. PMID:23985224

    The prevalence of waterpipe tobacco smoking is increasing worldwide, despite evidence indicating its adverse health effects. Women and young people seem more likely to be choosing waterpipe tobacco smoking over cigarettes. The objective of this qualitative study was to understand better whether and why waterpipe smoking is a more acceptable form of tobacco use than cigarettes for women in the Eastern Mediterranean Region, and to understand whether the strategies used by multi-national corporations to attract women to cigarette smoking were perceived to be relevant in the context of waterpipe tobacco use. Focus groups (n?=?81) and in-depth interviews (n?=?38) were conducted with adults in Lebanon, Egypt, Palestine, and Syria. Discussions were thematically analyzed and recurrent themes identified. One of the themes which emerged was the negative image of women smoking waterpipes. Moreover, the sexual allure conveyed through waterpipe smoking as well as waterpipe tobacco smoking as a symbol of emancipation was illustrated. The latter was mainly expressed in Lebanon, in contrast with Egypt where traditional gender roles depict women smoking waterpipes as disrespectful to society. Understanding the social aspects of waterpipe tobacco smoking is crucial to planning future interventions to control waterpipe tobacco smoking among women and in society at large. PMID:23421341

    The concentrations of environmental tobacco smoke (ETS) to which workers are exposed have been measured, using nicotine or other tracers, in diverse workplaces. Policies restricting workplace smoking to a few designated areas have been shown to reduce concentrations of ETS, although the effectiveness of such policies varies among work sites. Policies that ban smoking in the workplace are the most effective and generally lower all nicotine concentrations to less than 1 microg/m3; by contrast, mean concentrations measured in workplaces that allow smoking generally range from 2 to 6 microg/m3 in offices, from 3 to 8 microg/m3 in restaurants, and from 1 to 6 microg/m3 in the workplaces of blue-collar workers. Mean nicotine concentrations from 1 to 3 microg/m3 have been measured in the homes of smokers. Furthermore, workplace concentrations are highly variable, and some concentrations are more than 10 times higher than the average home levels, which have been established to cause lung cancer, heart disease, and other adverse health effects. For the approximately 30% of workers exposed to ETS in the workplace but not in the home, workplace exposure is the principal source of ETS. Among those with home exposures, exposures at work may exceed those resulting from home. We conclude that a significant number of U.S. workers are exposed to hazardous levels of ETS.

    Outdoor tobacco smoke (OTS) is concerned due to potential health effects. An assessment method of OTS exposure is needed to determine effects of OTS and validate outdoor smoking policies. The objective of this study was to develop a new method to assess OTS exposure. This study was conducted at 100 bus stops including 50 centerline bus stops and 50 roadside bus stops in Seoul, Korea. Using real-time aerosol monitor, PM2.5 was measured for 30 min at each bus stop in two seasons. ‘Peak analysis' method was developed to assess short term PM2.5 exposure by OTS. The 30-min average PM2.5 exposure at each bus stop was associated with season and bus stop location but not smoking activity. The PM2.5 peak occurrence rate by the peak analysis method was significantly associated with season, bus stop location, observed smoking occurrence, and the number of buses servicing a route. The PM2.5 peak concentration was significantly associated with season, smoking occurrence, and the number of buses servicing a route. When a smoker was standing still at the bus stop, magnitude of peak concentrations were significantly higher than when the smoker walking-through the bus stop. People were exposed to high short-term PM2.5 peak levels at bus stops, and the magnitude of peak concentrations were highest when a smoker was located close to the monitor. The magnitude of peak concentration was a good indicator helped distinguish nearby OTS exposure. Further research using ‘peak analysis' is needed to measure smoking-related exposure to PM2.5 in other outdoor locations.

    Tobacco smoking is one of the most common addictions. Epidemiological studies show a significant effect of smoking on oral health and the development of periodontal diseases. The purpose of this study is to analyze existing research on the impact of cigarette smoking on periodontal condition and present the benefits of tobacco quitting. In the mouth of a smoker comes to faster loss of connective tissue and bone, increased tooth mobility and greater number of missing teeth than non-smokers. The negative effects of smoking on periodontal tissues correlate with the length and frequency of smoking. Also, people exposed to environmental tobacco smoke (ETS) are at a higher risk of developing periodontal disease than those who had no contact with tobacco smoke. Quitting smoking has a positive effect on periodontal health and is an absolute prerequisite for the health of the entire oral cavity. With the prolongation of tobacco abstinence negative consequences for oral health are gradually reduced. Each patient should be aware of his addiction, the risks arising from exposure to tobacco smoke and be motivated to eliminate it. The role of general practitioners, particularly family doctors and dentists is crucial in evaluation of active and passive smoking as well as motivation and support smokers in quitting the habit and maintaining smoking abstinence.

    Background Known most commonly in the U.S. as “hookah,” waterpipe tobacco smoking appears to be growing among college students. Despite beliefs that waterpipe use is safer than cigarette smoking, research to date (albeit limited) has found health risks of waterpipe smoking are similar to those associated with cigarette smoking, including lung cancer, respiratory illness, and periodontal disease. The goals of this study were to estimate the prevalence of use among a large, multi-institution sample of college students and identify correlates of waterpipe use, including other health-risk behaviors (i.e., cigarette smoking, alcohol, marijuana, and other illicit drug use) and availability of commercial waterpipe tobacco smoking venues. Methods A cross-sectional sample of 3,770 college students from eight universities in North Carolina completed a web-based survey in fall 2008. Results Forty percent of the sample reported ever having smoked tobacco from a waterpipe, and 17% reported current (past 30-day) waterpipe tobacco smoking. Correlates associated with current waterpipe use included demographic factors (male gender, freshman class); other health-risk behaviors (daily and nondaily cigarette smoking, alcohol use, marijuana use, other illicit drug use); perceiving waterpipe tobacco smoking as less harmful than regular cigarettes; and having a commercial waterpipe venue near campus. Conclusions The results highlight the popularity of waterpipe tobacco smoking among college students and underscore the need for more research to assess the public health implications of this growing trend.

    The quantities of selenium, tar and nicotine present in mainstream (MS) and sidestream (SS) smoke of machine-smoked cigarettes was studied. The cigarettes were prepared from tobacco purposely cultured on fly ash-amended soil so as to increase its selenium concentration. Selenium concentration was found to be the same in the gaseous phase of both MS and SS smoke, but its concentration was significantly higher (p less than 0.05) in the particulate matter of the MS smoke. Tar was higher in MS smoke and nicotine in SS smoke. Factors affecting selenium concentrations in tobacco and its possible environmental significance are discussed.

    BACKGROUND School smoking bans give officials the authority to provide a smoke-free environment, but enacting policies within the school walls is just one step in comprehensive tobacco prevention among students. It is necessary to investigate factors beyond the school campus and into the neighborhoods that surround schools. The purpose of this study was to explore the relationship between the density of tobacco retailers and the illegal tobacco sales rate within school neighborhoods and smoking behaviors among students. METHODS This study utilized secondary data from the baseline of the Youth Tobacco Access Project. Data were collected from 10,662 students attending 21 middle schools and 19 high schools, in addition to 512 tobacco retailers, all within 24 towns in Illinois during 2002. A random-effects regression analysis was performed to assess the relationship between the density of tobacco retailers and illegal tobacco sales rates on current smoking and lifetime smoking prevalence. RESULTS Schools had a range of between zero and 9 tobacco retailers within their neighborhood with a mean of 2.76 retailers (SD= 2.45). The illegal sales rate varied from zero to 100%, with a mean of thirteen percent. The density of tobacco retailers was significantly related to the prevalence of ever smoking among students (b= 0.09, t(29) = 2.03, p = .051, OR = 1.10), but not to current smoking (p >.05); the illegal tobacco sales rate was not related to current smoking or lifetime smoking prevalence (p >.05). CONCLUSION Results indicate that tobacco retailer density may impact smoking experimentation/initiation PMID:23331271

    This study aims to examine beliefs among residents of Shanghai, China concerning tobacco advertising and control policies concurrent with new restrictions on tobacco use and advertising in the city. A total of 518 residents of Shanghai completed a telephone interview survey. We found that 51% of participants had seen or heard of the Zhonghua cigarette brand's 'Love China' tobacco ad campaign in the past 2 years, 59% believed that the campaign would influence people to buy this specific cigarette brand as a gift, and 30% believed that it would encourage smoking. More than 75% of respondents would support legislation banning tobacco advertising in all public places, and 88% would support legislation prohibiting smoking in all public places. Multivariate analyses indicated that those who were female, more than 50 years, have accepted college and above education, and perceived greater benefits to smoking cessation were more likely to support banning tobacco advertising and prohibiting smoking in public places. Non-smokers were more likely to support prohibiting smoking in public places. The findings suggest that although tobacco advertising is widely prevalent in Shanghai, it is disliked by the public. Respondents showed high levels of support for tobacco control policies. PMID:23912156

    Background Tobacco smoking and binge alcohol drinking are two of the leading risk factors for premature mortality worldwide. In India, studies have examined the geographic distributions of tobacco smoking and alcohol drinking only at the state-level; sub-state variations and the spatial association between the two consumptions are poorly understood. Methodology We used data from the Special Fertility and Mortality Survey conducted in 1998 to examine the geographic distributions of tobacco smoking and alcohol drinking at the district and postal code levels. We used kriging interpolation to generate smoking and drinking distributions at the postal code level. We also examined spatial autocorrelations and identified spatial clusters of high and low prevalence of smoking and drinking. Finally, we used bivariate analyses to examine the spatial correlations between smoking and drinking, and between cigarette and bidi smoking. Results There was a high prevalence of any smoking in the central and northeastern states, and a high prevalence of any drinking in Himachal Pradesh, Arunachal Pradesh, and eastern Madhya Pradesh. Spatial clusters of early smoking (started smoking before age 20) were identified in the central states. Cigarette and bidi smoking showed distinctly different geographic patterns, with high levels of cigarette smoking in the northeastern states and high levels of bidi smoking in the central states. The geographic pattern of bidi smoking was similar to early smoking. Cigarette smoking was spatially associated with any drinking. Smoking prevalences in 1998 were correlated with prevalences in 2004 at the district level and 2010 at the state level. Conclusion These results along with earlier evidence on the complementarities between tobacco smoking and alcohol drinking suggest that local public health action on smoking might also help to reduce alcohol consumption, and vice versa. Surveys that properly represent tobacco and alcohol consumptions at the district level are recommended. PMID:25025379

    Background Tobacco smoking entails inhaling millions of fine particles with each puff, and it is intuitive that after smoking a cigarette it will take a certain time to washout residual tobacco smoke (RTS) from the lungs with subsequent breaths. Objectives To study the washout time of 0.31.0?m particles after the last puff in 10 volunteer smokers by using equipment capable of measuring particle concentration in real time in the exhaled air. Result Mean (standard deviation (SD)) lung RTS washout time was 58.6 (23.6)?s, range 1890?s, and corresponded to 8.7 (4.6) subsequent breathings. The contribution of individual and overall RTS to indoor pollution was calculated by subtracting incremental background particle concentration from room concentration after 10 consecutive re?entries of smokers after the last puff into a room of 33.2?m3, with an air exchange rate per hour in the range of 0.20.4. Mean (SD) individual RTS contribution consisted of 1402 (1490) million particles (range 513611 million), whereas RTS increased room 0.31.0?m particle concentration from a baseline of 22?283?particles/l to a final room concentration of 341?956?particles/l, corresponding to a total increase in particulate matter (2.5) from a background of 0.56 up to 3.32?g/m3. Conclusion These data reveal a definite although marginal, role of RTS as a source of hidden indoor pollution. Further studies are needed to understand the relevance of this contribution in smoke?free premises in terms of risk exposure; however, waiting for about 2?min before re?entry after the last puff would be enough to avoid an unwanted additional exposure for non?smokers.

    OBJECTIVES: This prospective study examined the effect of tobacco marketing on progression to established smoking. METHODS: Massachusetts adolescents (n = 529) who at baseline had smoked no more than 1 cigarette were reinterviewed by telephone in 1997. Analyses examined the effect of receptivity to tobacco marketing at baseline on progression to established smoking, controlling for significant covariates. RESULTS: Adolescents who, at baseline, owned a tobacco promotional item and named a brand whose advertisements attracted their attention were more than twice as likely to become established smokers (odds ratio = 2.70) than adolescents who did neither. CONCLUSIONS: Participation in tobacco marketing often precedes, and is likely to facilitate, progression to established smoking. Hence, restrictions on tobacco marketing and promotion could reduce addiction to tobacco. PMID:10705860

  11. Determination of (+)-alpha-tocopherol in environmental tobacco smoke.

    A high-performance liquid chromatographic method is described for the quantitation of (+)-alpha-tocopherol in the particulate phase of environmental tobacco smoke (ETS) collected on a 1-micron pore size Fluoropore membrane. A methanol (MeOH) extract of the membrane, which can be used for four other ETS procedures, is analyzed for (+)-alpha-tocopherol on a reversed-phase column with fluorescence detection at selective wavelengths of 280 nm excitation and 330 nm emission. A mobile phase of MeOH and water is used. The method is reproducible with a relative standard deviation (%) of about 12. Recovery is 88%, and the procedure is capable of detecting greater than 0.04 microgram/m3 (+)-alpha-tocopherol in ETS. A comparison of the ETS from five commercially available cigarettes shows similar (+)-alpha-tocopherol concentrations. A cigarette that primarily heats tobacco yields about 6% of that amount of (+)-alpha-tocopherol found in ETS from tobacco-burning cigarettes. (+)-alpha-Tocopherol can be used as a marker for ETS respirable suspended particles (RSP) because it is found at a consistent amount in ETS RSP of 0.29%. However, sufficient amounts of RSP would have to be generated in order to detect (+)-alpha-tocopherol. PMID:9487671

    2012-09-01

    Tobacco control policy has been enacted in many jurisdictions worldwide banning smoking in the workplace. In the hospitality sector many businesses such as bars, hotels and restaurants have installed designated smoking areas on their premises and allowance for such smoking areas has been made in the tobacco control legislation of many countries. An investigation was carried out into the level of exposure to environmental tobacco smoke (ETS) present in 8 pubs in Ireland which included designated smoking areas complying with two different definitions of a smoking area set out in Irish legislation. In addition, ETS exposure in a pub with a designated smoking area not in compliance with the legislation was also investigated. The results of this investigation showed that the two differing definitions of a smoking area present in pubs produced similar concentrations of benzene within smoking areas (5.1-5.4 ?g/m(3)) but differing concentrations within the 'smoke-free' areas (1.42-3.01 ?g/m(3)). Smoking areas in breach of legislative definitions were found to produce the highest levels of benzene in the smoking area (49.5 ?g/m(3)) and 'smoke-free' area (7.68 ?g/m(3)). 3D exposure modelling of hypothetical smoking areas showed that a wide range of ETS exposure concentrations were possible in smoking areas with the same floor area and same smoking rate but differing height to width and length to width ratios. The results of this investigation demonstrate that significant scope for improvement of ETS exposure concentrations in pubs and in smoking areas may exist by refining and improving the legislative definitions of smoking areas in law.

    Estimates of lung cancer in nonsmokers due to exposure to environmental tobacco smoke (ETS) in the workplace or in the home may be developed in several ways. Estimates may be based on (italic)a(/italic)) models developed using the full range of data in smokers; (italic)b(/italic)) models developed using data restricted to smokers with a low smoking rate, for example, (3/4) 10 cigarettes per day; (italic)c(/italic)) models developed using data from studies of residential exposure to ETS of nonsmokers, with exposures based on smoking rates of spouses; and (italic)d(/italic)) models using data from studies of occupational exposure to ETS of nonsmokers. Methods (italic)a(/italic) and (italic)b(/italic) require an estimate of cigarette equivalent exposure for ETS as well as assumptions on the cigarette equivalent dose to target cells from ETS and on the comparability of lung cancer risk per unit dose from smokers and nonsmokers. Summary relative risks (RRs) and 95% confidence intervals (CI) from ETS studies of nonsmokers with exposures based on smoking patterns of spouses are 1.24 (1.1, 1.4) for females and 1.34 (1.0, 1.8) for males, whereas the RR estimate for occupational ETS exposure and its 95% CI is 1.39 (1.2, 1.7). Using RR estimates for ETS exposure, cigarette equivalents for ETS range from 0.1 to 1.0, based on a range of descriptive and biologically motivated models in active smokers; a cigarette equivalent is 0.2 based on a comparison of log-linear trends in RR with number of cigarettes smoked per day in active smokers and in spouses of nonsmokers.

  14. Lung cancer and environmental tobacco smoke: occupational risk to nonsmokers.

    PubMed Central

    Brown, K G

    1999-01-01

    The principal epidemiologic evidence that environmental tobacco smoke (ETS) increases the risk of lung cancer in (lifelong) nonsmokers is from studies of nonsmoking women married to smokers. This article estimates exposure-response curves for 14 studies (1, 249+ cases, 7 countries) with data on lung cancer categorized by the number of cigarettes/day smoked by the husband. The pooled results from the five U.S. studies alone are extrapolated to ETS levels in the workplace using measures of serum cotinine and nicotine samples from personal monitors as markers of exposure to ETS. It is predicted that the increase in lung cancer risk for nonsmoking women from average ETS exposure at work (among those exposed at work) is on the order of 25% (95% confidence interval (CI) = 8, 41) relative to background risk (i.e., with no ETS exposure from any source). This compares to an estimate of 39% (95% CI = 5, 65) for nonsmoking women whose husbands smoke at the adult male smoker's average of 25 cigarettes/day. At the 95th percentiles of exposure, the estimate from spousal smoking is 85% (95% CI = 32, 156), compared to 91% (95% CI = 34, 167) from workplace ETS exposure. Subject to the validity of the assumptions required in this approach, the outcome supports the conclusion that there is a significant excess risk from occupational exposure to ETS. The excess risk from ETS at work is typically lower than that from spousal smoking, but may be higher at the 95th percentiles of exposure. PMID:10592148

    1995-04-01

    Airbags have been shown to reduce injuries and save the lives of car occupants in a crash. Like any protection system, airbags potentially introduce some new risks if no appropriate countermeasures are taken. A case of a relatively moderate frontal impact is described where the driver of an airbag-equipped car suffered a severe penetrating eye injury after the airbag deployed. Since the airbag fabric itself was excluded as an injury-producing structure, other objects such as eyeglasses, a wrist-watch, a bracelet, and a large finger ring had to be assessed. The investigation of the car interior as well as the morphologic details of the injuries to the eye and the face revealed that the most likely candidate for the injury was a tobacco pipe, which was probably being held in one hand and was broken apart by the deploying airbag and projected into the face of the driver. This case illustrates the hazard of having any rigid object between the occupant and the deploying airbag. The desirability of warning car occupants of the potential hazards which can result from today's protection systems is also discussed. PMID:7723086

    Objectives: A variety of smoked and smokeless tobacco products with varying nicotine content are accessible in India. Nicotine quantity in tobacco products has direct bearing on tobacco dependence. Our objective was to estimate nicotine content in various types of smoked and smokeless products. Disclosure for essential health warning was also checked. Materials and Methods: Liquid-liquid extraction was used for nicotine extraction and high-performance thin layer chromatography technique was applied for quantification of nicotine in seventy-one smoked and smokeless tobacco products. Results: Significant variation in nicotine content was observed across products. In smoked tobacco, nicotine content varied from 1.01 to 13.0 mg/rod, while in smokeless tobacco products it ranged from 0.8 mg/g to 50.0 mg/g. Moisture content varied from 9% to 21%. Conclusion: This work lists a range of smoked and smokeless tobacco products available in this region. We report a wide variability in nicotine quantity across smoked and smokeless tobacco products. Such variation in nicotine content may have important implications for tobacco cessation interventions and policies PMID:26288479

  19. Environmental tobacco smoke particles in multizone indoor environments

    Miller, S. L.; Nazaroff, W. W.

    Environmental tobacco smoke (ETS) is a major source of human exposure to airborne particles. To better understand the factors that affect exposure, and to investigate the potential effectiveness of technical control measures, a series of experiments was conducted in a two-room test facility. Particle concentrations, size distributions, and airflow rates were measured during and after combustion of a cigarette. Experiments were varied to obtain information about the effects on exposure of smoker segregation, ventilation modification, and air filtration. The experimental data were used to test the performance of an analytical model of the two-zone environment and a numerical multizone aerosol dynamics model. A respiratory tract particle deposition model was also applied to the results to estimate the mass of ETS particles that would be deposited in the lungs of a nonsmoker exposed in either the smoking or nonsmoking room. Comparisons between the experimental data and model predictions showed good agreement. For time-averaged particle mass concentration, the average bias between model and experiments was less than 10%. The average absolute error was typically 35%, probably because of variability in particle emission rates from cigarettes. For the conditions tested, the use of a portable air filtration unit yielded 65-90% reductions in predicted lung deposition relative to the baseline scenario. The use of exhaust ventilation in the smoking room reduced predicted lung deposition in the nonsmoking room by more than 80%, as did segregating the smoker from nonsmokers with a closed door.

    Background Tobacco smoking is a growing public health problem in the developing world. There is paucity of data on smoking and predictors of smoking among school-going adolescents in most of sub-Saharan Africa. Hence, the aim of this study is to estimate the prevalence of smoking and its associations among school-going adolescents in Addis Ababa, Ethiopia. Methods Data from the Global Youth Tobacco Survey (GYTS) 2003 were used to determine smoking prevalence, determinants, attitudes to, and exposure to tobacco advertisements among adolescents. Results Of the 1868 respondents, 4.5% males and 1% females reported being current smokers (p < 0.01). Having smoking friends was strongly associated with smoking after controlling for age, gender, parental smoking status, and perception of risks of smoking (OR = 33; 95% CI [11.6, 95.6]). Male gender and having one or both smoking parents were associated with smoking. Perception that smoking is harmful was negatively associated with being a smoker (odds ratio 0.3; 95% confidence interval, 0.2–0.5) Conclusion Prevalence of smoking among adolescents in Ethiopia is lower than in many other African countries. There is however need to strengthen anti-tobacco messages especially among adolescents. PMID:17651482

    Background Tobacco use among cancer patients is associated with adverse health outcomes. Little attention has been paid to tobacco use among cancer patients in developing countries, including Russia, where tobacco use is extremely high, and there is little public health infrastructure to address this issue. Purpose This study examined medical, socio-demographic, and psychological correlates of smoking status and intention to quit smoking among newly diagnosed Russian cancer patients. Method A cross-sectional study was conducted with 294 current or former smokers newly diagnosed with cancer. Results Compared with patients who quit smoking, patients who continued to smoke were more likely to report urges to smoke to satisfy positive reinforcing aspects of tobacco use. Compared with patients who were smoking and reported no intention to quit smoking in the next 3 months, patients who were smoking but intended to quit smoking reported higher levels of perceived risks associated with continued smoking and higher levels of self-efficacy to quit smoking. Conclusion As commitment to developing smoking cessation treatment programs for caner patients in Russia emerges, these data can help guide the development of behavioral interventions to assist patients with quitting smoking, enhancing their chances for improved clinical outcomes.

    Objectives. We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). Methods. We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. Results. Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. Conclusions. Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking. PMID:23327252

    This study investigates the role of tobacco outlet density in a randomized controlled trial of a text messaging-based smoking cessation intervention conducted among a sample of 187 primarily African American youth in a midsize U.S. city. A moderated mediation model was used to test whether the indirect effect of residential tobacco outlet density on future smoking was mediated by the intention to smoke, and whether this indirect effect differed between adolescents who received the intervention and those who did not. Results indicated that tobacco outlet density is associated with intention to smoke, which predicts future smoking, and that the indirect effect of tobacco outlet density on future smoking is moderated by the intervention. Tobacco outlet density and the intervention can be viewed as competing forces on future smoking behavior, where higher tobacco outlet density acts to mitigate the sensitivity of an adolescent to the intervention's intended effect. Smoking cessation interventions applied to youth should consider tobacco outlet density as a contextual condition that can influence treatment outcomes. PMID:26798960

    Smoking is a risk factor for lung diseases, including chronic obstructive pulmonary disease and lung cancer. However, the molecular mechanisms mediating the progression of these diseases remain unclear. Therefore, we sought to identify signaling pathways activated by tobacco-smoke exposure, by analyzing nuclear phosphoprotein expression using phosphoproteomic analysis of lung tissue from mice exposed to tobacco smoke. Sixteen mice were exposed to tobacco smoke for 1 or 7days, and the expression of phosphorylated peptides was analyzed by mass spectrometry. A total of 253 phosphoproteins were identified, including FACT complex subunit SPT16 in the 1-day exposure group, keratin type 1 cytoskeletal 18 (K18), and adipocyte fatty acid-binding protein, in the 7-day exposure group, and peroxiredoxin-1 (OSF3) and spectrin ? chain brain 1 (SPTBN1), in both groups. Semi-quantitative analysis of the identified phosphoproteins revealed that 33 proteins were significantly differentially expressed between the control and exposed groups. The identified phosphoproteins were classified according to their biological functions. We found that the identified proteins were related to inflammation, regeneration, repair, proliferation, differentiation, morphogenesis, and response to stress and nicotine. In conclusion, we identified proteins, including OSF3 and SPTBN1, as candidate tobacco smoke-exposure markers; our results provide insights into the mechanisms of tobacco smoke-induced diseases.

    Objective Water-pipe and smokeless tobacco use have been associated with several adverse health outcomes. However, little information is available on the association between water-pipe use and heart disease (HD). Therefore, we investigated the association of smoking water-pipe and chewing nass (a mixture of tobacco, lime, and ash) with prevalent HD. Design Cross-sectional study. Setting Baseline data (collected in 20042008) from a prospective population-based study in Golestan Province, Iran. Participants 50,045 residents of Golestan (4075 years old; 42.4% male). Main outcome measures ORs and 95% CIs from multivariate logistic regression models for the association of water-pipe and nass use with HD prevalence. Results A total of 3051 (6.1%) participants reported a history of HD, and 525 (1.1%) and 3726 (7.5%) reported ever water-pipe or nass use, respectively. Heavy water-pipe smoking was significantly associated with HD prevalence (highest level of cumulative use versus never use, OR= 3.75; 95% CI 1.52 9.22; P for trend= 0.04). This association persisted when using different cutoff points, when restricting HD to those taking nitrate compound medications, and among never cigarette smokers. There was no significant association between nass use and HD prevalence (highest category of use versus never use, OR= 0.91; 95% CI 0.69 1.20). Conclusions Our study suggests a significant association between HD and heavy water-pipe smoking. Although the existing evidence suggesting similar biological consequences of water-pipe and cigarette smoking make this association plausible, results of our study were based on a modest number of water-pipe users and need to be replicated in further studies.

    Experimental studies on the removal of accumulated environmental tobacco smoke (ETS) and the effectiveness of ETS leakage control were carried out in a model smoking room using carbon monoxide, nicotine, 3-ethenylpyridine, respirable suspended particulates, and ultrafine particles (UFP) as the ETS tracers. The study investigated the effectiveness of the designated smoking room, equipped with a displacement ventilation system under different ventilation rates (10-58 L/sec per person,) in removing the ETS tracers. The extent of ETS leakage through different door operating scenarios under various ventilation rates was intensively studied. In particular, a manikin installed on a motorized rail was used to study the effect of human movement on the leakage of the ETS tracers. A double-door anteroom design was incorporated into the smoking room to study its effectiveness in ETS leakage prevention. It shows that at least 5 Pa of negative pressure, a fresh air supply rate 3-5 times higher than a typical office, direct air exhaust without air recirculation, and keeping the door closed are important for reducing ETS leakage. However, with the smokers moving in and out and the opening of the door, noticeable leakage of ETS can occur. The double-door anteroom design can improve leakage prevention. Among the five tracers, nicotine required the longest purging time to remove, after the smoking activity was stopped in the smoking room, due to its highly sorptive property. At least 4.4-6 hr of purging is needed for minimizing ETS exposure by non-smokers entering the smoking room. The peak size of particulate matter inside the smoking room is about 80-100 nm, suggesting the importance of including UFP as an indicator for monitoring the exposure and leakage of ETS. The impact of manikin movement on contaminant transport was studied, providing useful information on the effects of human activities on indoor air quality multicompartmental modeling. PMID:20694932

    The Albania SimSmoke simulation model is used to examine the effects of tobacco control policies. The model is used to consider the projected trends in smoking prevalence and associated smoking-attributable deaths in the absence of new policies, and then to examine the effect of new policies that are consistent with the Framework Convention for Tobacco Control (FCTC) on these outcomes. The model shows that significant inroads to reducing smoking prevalence and premature mortality can be achieved through tax increases. Acomprehensive strategy to further reduce smoking rates should include a media campaign complete with programs to publicize and enforce clean air laws, a comprehensive cessation treatment program, strong health warnings, advertising bans, and youth access laws. Besides presenting the benefits of a comprehensive tobacco control strategy, the model helps to identify important information needed for both modeling and policymaking. The effectiveness of future tobacco control policy will require proper surveillance and evaluation schemes for Albania. PMID:19256288

    The concentrations of environmental tobacco smoke (ETS) constituents including benzene were measured in the living rooms of 10 nonsmoking households and 20 households with at least one smoker situated in the city and suburbs of Munich. In the city, the median benzene levels during the evening, when all household members were at home, were 8.1 and 10.4 {mu}g/m{sup 3} in nonsmoking and smoking homes, respectively. The corresponding levels of 3.5 and 4.6 {mu}g/m{sup 3} were considerably lower in the suburbs. Median time-integrated 1-week benzene concentrations in the city were 10.6 {mu}g/m{sup 3} in nonsmoking homes and 13.1 {mu}g/m{sup 3} in smoking homes. In the suburbs, the corresponding values were 3.2 and 5.6 {mu}g/m{sup 3}. No difference was found between smoking and nonsmoking households located either in the city or in the suburbs. There was no statistically significant difference between benzene exposure of non-smokers in smoking and nonsmoking homes. Nonsmokers living in nonsmoking households in the city had significantly higher exposure to benzene compared to their counterparts living in the suburban. Nonsmokers from all households with smokers were significantly more exposed to benzene than nonsmokers living in the nonsmoking households (personal samplers: 13.2 vs. 7.0 {mu}g/m{sup 3}, p < 0.05; benzene in exhalate: 2.6 vs. 1.8 {mu}g/m{sup 3}, p < 0.01; trans-muconic acid excretion in urine: 73 vs. 62 {mu}g/g creatinine), but the contribution of ETS to the total benzene exposure was relatively low compared to that from other sources. Analysis of variance showed that at most 15% of the benzene exposure of nonsmokers living in smoking homes was attributable to ETS. For nonsmokers living in nonsmoking households benzene exposure from ETS was insignificant.

    Environmental Tobacco Smoke (ETS) is a major component in indoor and outdoor air pollution. It has been estimated that ETS accounts for approximately 2.7% of fine organic aerosol emissions in the Los Angeles area and the adverse health effects of cigarette emissions have been well documented. Particulate analysis by conventional analytical methods, such as GC/MS, do not provide information on individual aerosol particles due to the off-line collection and sampling procedures. Aerosol Time-Flight Mass Spectrometry is an on-line analytical technique that is uniquely capable of single particle analysis, simultaneously providing information on particle size and chemical composition. It will be demonstrated that this technique can be used to show how the chemical composition of ETS particles changes as a function of size. Data demonstrating the ability to monitor chemical composition and size change as a function of time will also be presented.

    OBJECTIVETo assess the relation between adolescents' favourite movie stars, the portrayal of tobacco use by those stars in contemporary motion pictures, and adolescent smoking.?DESIGN AND SETTING632 students (sixth to 12th grade, ages 10-19 years) from five rural New England public schools completed a voluntary, self administered survey in October 1996.The survey assessed tobacco use, other variables associated with adolescent smoking, and favourite movie star. In addition, tobacco use by 43selected movie stars was measured in films between 1994and 1996.?OUTCOME MEASURESStudents were categorised into an ordinal five point index (tobacco status) based on their smoking behaviour and their smoking susceptibility: non-susceptible never smokers, susceptible never smokers, non-current experimenters, current experimenters, and smokers. We determined the adjusted cumulative odds of having advanced smoking status based on the amount of on-screen tobacco use by their favourite film star.?RESULTSOf the 43stars, 65% used tobacco at least once, and 42% portrayed smoking as an essential character trait in one or more films. Stars who smoked more than twice in a film were considered smokers. For adolescents whose favourite stars smoked in only one film, the odds of being higher on the smoking index was 0.78(95% confidence interval (CI) 0.53to 1.15). For adolescents whose favourite stars smoked in two films, the odds of being higher on the smoking index was 1.5(95% CI 1.01to 2.32). For adolescents whose favourite stars smoked in three or more films (Leonardo DiCaprio, Sharon Stone, John Travolta), the odds of being higher on the smoking index was 3.1(95% CI 1.34to 7.12). Among never smokers (n=281), those who chose stars who were smokers in three or more films were much more likely to have favourable attitudes toward smoking (adjusted odds ratio 16.2,95% CI 2.3to 112).?CONCLUSIONSAdolescents who choose movie stars who use tobacco on-screen are significantly more likely to have an advanced smoking status and more favourable attitudes toward smoking than adolescents who choose non-smoking stars. This finding supports the proposition that the portrayal of tobacco use in contemporary motion pictures, particularly by stars who are admired by adolescents, contributes to adolescent smoking.???Keywords: adolescent smoking; movies; media influences PMID:11226355

    Background Russia has high smoking rates and weak tobacco control policies. A simulation model is used to examine the effect of tobacco control policies on past and future smoking prevalence and premature mortality in Russia. Methods The Russia model was developed using the SimSmoke tobacco control model previously developed for the USA and other nations. The model inputs population size, birth, death and smoking rates specific to Russia. It assesses, individually and in combination, the effect of seven types of policies consistent with the WHO Framework Convention on Tobacco Control (FCTC): taxes, smoke-free air, mass media campaign, advertising bans, warning labels, cessation treatment and youth access policies. Outcomes are smoking prevalence and the number of smoking-attributable deaths by age and gender from 2009 to 2055. Results Increasing cigarette taxes to 70% of retail price, stronger smoke-free air laws, a high-intensity media campaign and comprehensive treatment policies are each potent policies to reduce smoking prevalence and smoking-attributable premature deaths in Russia. With the stronger set of policies, the model estimates that, relative to the status quo trend, smoking prevalence can be reduced by as much as 30% by 2020, with a 50% reduction projected by 2055. This translates into 2 684 994 male and 1 011 985 female premature deaths averted from 20152055. Conclusions SimSmoke results highlight the relative contribution of policies to reducing the tobacco health burden in Russia. Significant inroads to reducing smoking prevalence and premature mortality can be achieved through strengthening tobacco control policies in line with FCTC recommendations. PMID:23853252

  15. Secondhand Smoke | Cancer Trends Progress Report

    Cancer.gov

    Secondhand smoke (SHS), also known as environmental tobacco smoke, is a mixture of the sidestream smoke released by a smoldering cigarette, pipe, or cigar, and the mainstream smoke exhaled by a smoker. Like mainstream smoke, SHS is a complex mixture containing thousands of chemicals, including formaldehyde, cyanide, carbon monoxide, ammonia, and nicotine. More than 250 of the chemicals in tobacco smoke are known to be harmful, and at least 69 are known to cause cancer.

    The effect of whole tobacco smoke and the gas phase of tobacco smoke on the metabolism and phagocytic ability of alveolar macrophages was monitored over a 30-day exposure period. It was demonstrated that both the gas phase and whole tobacco smoke induced a weight loss in exposed rats. Alveolar macrophage oxygen consumption was markedly increased by both exposure regimens. Superoxide generation was not affected by whole tobacco smoke exposure but was increased in response to the filtered gas phase. Hexose monophosphate shunt activity was not altered by either treatment. When metabolic alterations were seen in response to the separate exposures, they were seen only after a phagocytic challenge to the macrophage and not when the cell was unchallenged. Neither whole tobacco smoke nor the gas phase had any significant effect on the ability of alveolar macrophages to phagocytize a viable challenge of Staphylococcus aureus. Our results suggest that many of the metabolic and functional effects of tobacco smoke on alveolar macrophages can be attributed to the gas-phase component of whole tobacco smoke.

  17. Biomonitoring exposure to environmental tobacco smoke (ETS): a critical reappraisal.

    1 The most frequently used biomarkers for exposure to environmental tobacco smoke (ETS) are cotinine and thiocyanate in body fluids, carboxyhaemoglobin in red blood cells (COHb) and carbon monoxide in the expired air. Although not ideal, cotinine in blood, saliva or urine is an established biomarker for ETS exposure within the past 1-3 days. Comparison with cotinine concentrations in cigarette smokers reveals that passive smokers take up less than 1/100 of the nicotine dose of smokers. 2 Biomonitoring data available for the ETS-related exposure to genotoxic substances comprise uptake of benzene, polycyclic aromatic hydrocarbons (PAH), aromatic amines, tobacco-specific nifrosamines (TSNA), electrophilic compounds giving rise to urinary thioethers, mutagens causing urinary mutagenic activity and the formation of various DNA adducts. With the exception of TSNA, these biomarkers are related to chemicals occurring ubiquitously in the environment and in the food. As a consequence, the background levels in unexposed nonsmokers are high compared to the observed increases (if any) associated with ETS exposure. 3 Some markers of biological effects, which, by definition, are non-specific with regard to the underlying exposure, have also been investigated in relation to ETS exposure. These markers comprise cytogenetic effects, aryl hydrocarbon hydroxylase (AHH) induction, urinary hydroxyproline excretion and various factors indicative of cardiovascular risks. The available data suggest that passive smoking is associated with a small induction of placental AHH and also with effects on cardiovascular risk markers. The latter findings in particular may be confounded by other risk factors, which have been observed to be more frequent in passive smokers than in unexposed nonsmokers. PMID:9292285

    India ratified the WHO's Framework Convention on Tobacco Control in February 2004 and enacted legislation called, "Cigarettes and Other Tobacco Products (Prohibition of Advertisement and Regulation of Trade and Commerce, Production, Supply and Distribution) Act 2003" which specifically called for an end to direct and indirect form of tobacco advertisements. Under its Section 7, the Act also stipulates depiction of pictorial health warnings on all tobacco products. Since the enactment of the legislation, the tobacco companies are prohibited from any kind of advertisement. However, studies show that the instances of showing smoking in movies have increased significantly to 89% after the implementation of the Act. The brand placement has been also increased nearly three folds. Association of tobacco with glamour and style has also been established. Seventy-five percent of movies have showed the lead character smoking tobacco. The instances of females consuming tobacco in movies have also increased, pointing toward a specific market expansion strategy by tobacco companies using movies as a vehicle. General public does not feel that banning tobacco scenes in the movie will affect their decision to watch movies or the quality of movies. It was found that favorable images through mass media created a considerable influence on youngsters and increased their receptivity to tobacco smoking. Pictorial warning on tobacco products is yet to start. Tobacco industry's opposition to tobacco health warnings is understandable as it will adversely affect their business. However, policymakers should not evade their responsibility to mandate strong health warnings on all tobacco product packs. Legal action against offenders, investigation of the relationship and financial irregularities between film-makers and tobacco industry, and recall of the movies showing tobacco brand are the important measures recommended.

    Physicians should play a leading role in combatting smoking; information on attitudes of future physicians towards tobacco control measures in a middle-income developing country is limited. Of 310 future physicians surveyed in a medical school in Malaysia, 50% disagreed that it was a doctor's duty to advise smokers to stop smoking; 76.8% agreed that physicians should not smoke before advising others not to smoke; and 75% agreed to the ideas of restricting the sale of cigarettes to minors, making all public places smoke-free and banning advertising of tobacco-related merchandise. Future physicians had positive attitudes towards tobacco regulations but had not grasped their responsibilities in tobacco control measures. PMID:22668450

    1990-05-01

    The origin of tobacco-specific nitrosamines (TSNA) in mainstream smoke and the possible contribution of synthesis during the smoking procedure was investigated. Addition of the nitrosamine precursors nitrate and nicotine to the tobacco prior to smoking did not change the mainstream smoke concentrations of N'-nitrosonornicotine (NNN) and 4-(methyl-nitrosamino)-1-(3-pyridyl)-1-butanone (NNK), whereas the mainstream smoke concentration of N'-nitrosoanabasine (NAB) and N'-nitrosoanatabine (NAT) increased after spiking the cigarettes with nitrate. Data for TSNA in tobacco and in mainstream smoke and for nitrate in tobacco of commercial cigarettes of the West German market, taken from previous investigations, were used to calculate the mainstream smoke/tobacco ratios for NNN and NNK. These ratios were corrected for ventilation and cigarette length. It is shown that the ratios are constant and neither depend on the nicotine level nor on the nitrate level of the tobacco except for NNK in the nitrate rich dark tobacco type cigarettes. For nonfilter cigarettes the transfer rates of NNN and NNK which had been corrected for ventilation and cigarette length amounted to 23 or 34% respectively. For filter cigarettes a transfer rate of 13% for NNN and 23% for NNK was calculated. Furthermore it is shown that the mainstream smoke/tobacco ratios for NNN and NNK are constant over the whole length of the cigarettes except for NNK in dark tobacco type cigarettes. The results of this investigation indicate that pyrosynthesis of NNN does not occur and that it is very unlikely for NNK at least for lower nitrate levels. Thus with few exceptions the TSNA burden of smokers is predominantly influenced by the amount of preformed NNN and NNK in tobacco. PMID:2335004

    Secondhand smoke exposure is estimated to account for 3000 cancer deaths per year. While several countries and states in the U.S. have passed comprehensive smoke-free laws to protect all employees, a significant number of workers are still not protected. The purpose of this study was to determine the effects of passing a comprehensive smoking ban that included bars and restaurants on biomarkers of nicotine and carcinogen exposure. The urines of non-smoking employees (N=24) of bars and restaurants that allowed smoking prior to the smoke-free law were analyzed before and after the law was passed in Minnesota. The results showed significant reductions in both total cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) (free plus glucuronidated) after the ban was instituted. These results provide further support for the importance of protecting employees working in all venues. PMID:20354127

    The aim of present study was to estimate the nephrotoxicity of occupational exposure to heavy metals on albumin concentration and β-glucuronidase activity in the urine of smoking and non-smoking smelters. The study was performed in urine of 101 smoking and non-smoking smelters as well as 65 smoking and non-smoking male subjects unexposed to heavy metals. Section into smoking and non-smoking groups was made on basis on direct personal interview and by determination of serum cotinine concentration. The concentration of albumin in urine was measured with commercial test (Micro-Albumin ELISA Cat. No 5MA 74212, ORGENTEC Diagnostika Gmbh, Germany). The activity of β-glucuronidase in urine were determined in urine using 4-nitrophenyl β D-glucuronide (Cat. No 73677, Sigma Aldrich, Germany) as a substrate. We have observed higher albumin concentration and β-glucuronidase activity in urine of smoking and non-smoking smelters when compared to control groups. We have also found the influence of tobacco smoke as well as amount of cigarettes smoked on albumin concentration in urine of smoking smelters. A statistically significant difference was detected between activity of β-glucuronidase in urine of smoking and non-smoking smelters, which suggest as additional negative factor of exposure to tobacco smoke. Analyzing the impact of smoking intensity we have found higher albumin concentration and β-glucuronidase activity in urine of smelters smoking ≥20 cigarettes per day when compared to smelters smoking <20 cigarettes per day. The elevation of albumin concentration and β-glucuronidase activity in urine of workers occupational exposure to heavy metals and tobacco smoke indicated, that environmental exposure on these factors can disorders kidney functions.

    In this study, concentrations of Cd, Ni, Pb, and Cr were determined in tobacco, tobacco smoke-condensate, and cigarette ash for selected brands used in Pakistan. Smoking apparatus was designed for metal extraction from cigarette smoke. Samples were digested through microwave digester and then analyzed by flame atomic absorption spectrophotometer (FAAS). Higher concentration of Ni was detected in imported brands than the counterparts in the local brands. Pb levels were however higher in local brands while significant concentration of Cd was observed in both brands. For Cr, the level in tobacco of local brands was higher than their emitted smoke, whereas imported brands showed higher level in smoke than in tobacco. The cigarette ash retained 65 to 75% of the metal and about 25 to 30% went into the body. While this study revealed the serious requirement to standardize the manufacturing of tobacco products, more importantly is the urgent need for stronger enforcements to put in place to alert the general population about the hazardous effects of cigarettes and the health risks associated with these toxic metals.

    Introduction: Nicotine has long been recognized as a necessary but insufficient component of tobacco cigarettes to maintain a psychophysiological need to smoke. This study examined venous plasma concentrations effects of nicotine in cigarette smoking after overnight abstinence to release striatal dopamine (DA). Methods: Twenty-two male smokers smoked either denicotinized (denic) or average nicotine (nic) cigarettes under single blind conditions. Each was given [11C]raclopride and scanned in a positron emission tomography (PET) facility. Results: Smoking either denic or nic cigarettes released striatal DA. Denic cigarette smoking released DA primarily in the right striatum, whereas nic cigarette smoking released DA in both striata, but especially in the left. Increases in venous plasma nicotine concentrations correlated positively with increased DA release in the left caudate nucleus. Smoking denic cigarettes reduced craving as much as smoking nic cigarettes. Craving reduction after nic tobacco smoking correlated with increases in plasma nicotine. Conclusions: Nonnicotine factors in tobacco smoking produce important right brain effects. Nicotine is a pharmacological factor during tobacco smoking that releases bilateral striatal DA, but more in the left brain. PMID:22491891

    Objective To determine what the tobacco industry knew about the potential effects of menthol on smoking topographyhow a person smokes a cigarette. Methods A snowball strategy was used to systematically search the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) between 1 June 2010 and 9 August 2010. We qualitatively analysed a final collection of 252 documents related to menthol and smoking topography. Results The tobacco industry knew that menthol has cooling, anaesthetic and analgesic properties that moderate the harshness and irritation of tobacco. Owing to its physiological effects, menthol contributes to the sensory qualities of the smoke and affects smoking topography and cigarette preference. Conclusion Our review of industry studies suggests that the amount of menthol in a cigarette is associated with how the cigarette is smoked and how satisfying it is to the smoker. If menthol in cigarettes was banned, as the US Food and Drug Administration (FDA) is currently considering, new/experimental smokers might choose not to smoke rather than experience the harshness of tobacco smoke and the irritating qualities of nicotine. Similarly, established menthol smokers might choose to quit if faced with an unpleasant smoking alternative. PMID:21504930

    Susceptibility to smoking has been identified as predictor of smoking onset in adolescence. Aim of the study was to investigate whether receptivity to tobacco marketing, for which a link to adolescent smoking already could be shownin the past, was also associated with susceptibility to smoking. A cross-sectional survey of 1,478 Polish students who reported having never smoked wasconducted. Mean age was 10.1 years and about 53.3% were female. Overall, 84 (5.7%) students were classifiedas susceptible to smoking, and 33 (2.3%) were considered as receptiveto tobacco marketing, operationalised by asking students to name a brand of their favourite cigarette advertisement. Crude logistic regression analyses as well as logistic regression analyses adjusting for socio-demographic characteristics, personality characteristics, factors of social influence and smoking-related cognitions revealed a positive association between receptivity to tobacco marketing and susceptibility to smoking (adjusted odds ratio=3.49 [95% confidence interval: 1.28-9.46], p=0.014). In conclusion, this study revealed that receptivityto tobacco marketing increases susceptibility to smoking. Results providesupport for the almost comprehensive ban of tobacco marketing as existing in Poland and recommend its further expansion towards a total ban including e.g. ban of promotion at point of sale.

    Like tobacco smoking, habitual marijuana smoking causes numerous adverse pulmonary effects. However, the mechanisms of action involved, especially as compared to tobacco smoke, are still unclear. To uncover putative modes of action, this study employed a toxicogenomics approach to compare the toxicological pathways perturbed following exposure to marijuana and tobacco smoke condensate in vitro. Condensates of mainstream smoke from hand-rolled tobacco and marijuana cigarettes were similarly prepared using identical smoking conditions. Murine lung epithelial cells were exposed to low, medium and high concentrations of the smoke condensates for 6h. RNA was extracted immediately or after a 4h recovery period and hybridized to mouse whole genome microarrays. Tobacco smoke condensate (TSC) exposure was associated with changes in xenobiotic metabolism, oxidative stress, inflammation, and DNA damage response. These same pathways were also significantly affected following marijuana smoke condensate (MSC) exposure. Although the effects of the condensates were largely similar, dose-response analysis indicates that the MSC is substantially more potent than TSC. In addition, steroid biosynthesis, apoptosis, and inflammation pathways were more significantly affected following MSC exposure, whereas M phase cell cycle pathways were more significantly affected following TSC exposure. MSC exposure also appeared to elicit more severe oxidative stress than TSC exposure, which may account for the greater cytotoxicity of MSC. This study shows that in general MSC impacts many of the same molecular processes as TSC. However, subtle pathway differences can provide insight into the differential toxicities of the two complex mixtures. PMID:23542559

    There are established guidelines for bioanalytical assay validation and qualification of biomarkers. In this review, they were applied to a panel of urinary biomarkers of tobacco smoke exposure as part of a “fit for purpose” approach to the assessment of smoke constituents exposure in groups of tobacco product smokers. Clinical studies have allowed the identification of a group of tobacco exposure biomarkers demonstrating a good doseresponse relationship whilst others such as dihydroxybutyl mercapturic acid and 2-carboxy-1-methylethylmercapturic acid – did not reproducibly discriminate smokers and non-smokers. Furthermore, there are currently no agreed common reference standards to measure absolute concentrations and few inter-laboratory trials have been performed to establish consensus values for interim standards. Thus, we also discuss in this review additional requirements for the generation of robust data on urinary biomarkers, including toxicant metabolism and disposition, method validation and qualification for use in tobacco products comparison studies.

    The extraction of fenpropathrin, cyhalothrin, cypermethrin, fenvalerate and deltamethrin from tobacco (Nicotina tobaccum) and cigarette smoke condensate with acetone, followed by partition of resulting acetone mixture with petroleum ether, was investigated and found suitable for capillary gas chromatography (GC) residue analysis. Florisil column clean-up was found to provide clean-up procedure for tobacco and cigarette smoke condensate permitting analysis to < or = 0.01 microgram.g-1 for most of the pyrethroids by GC with a 63Ni electron capture detector (GC-ECD). Quantitative determination was obtained by the method of external standards. Cigarettes made from flue-cured tobacco spiked with different amounts of pyrethroids were used and the pyrethroid levels in mainstream smoke were determined. For all the pyrethroid residues, 1.51-15.50% were transferred from tobacco into cigarette smoke. PMID:12198849

    Aims To examine differential effects of smoking in films and tobacco advertising on adolescent smoking. We hypothesize that movie smoking will have greater effects on smoking initiation, whereas tobacco advertising receptivity will primarily affect experimentation. Design Longitudinal observational study of adolescents. Setting School-based surveys conducted in Schleswig-Holstein, Germany. Participants A total of 4384 adolescents age 11–15 years at baseline and re-surveyed 1 year later; ever smoking prevalence was 38% at time 1. Measurements The main outcome variable combined two items assessing life-time and current smoking (alpha = 0.87). Baseline never smokers were analyzed separately from those who had tried smoking (ever smokers). Exposure to smoking in 398 internationally distributed US movies was modeled as a continuous variable, with 0 corresponding to the 5th percentile and 1 to the 95th percentile of exposure. Tobacco marketing receptivity consisted of naming a brand for a favorite tobacco advertisement. Ordinal logistic regressions controlled for socio-demographics, other social influences, personality characteristics of the adolescent and parenting style. Findings Whereas 34% of ever smokers were receptive to tobacco marketing at time 1, only 6% of never smokers were. Among time 1 never smokers, exposure to movie smoking was a significantly stronger predictor of higher time 2 smoking level [adjusted proportional odds ratio = 2.76, 95% confidence interval (1.84, 4.15)] than was tobacco marketing receptivity (1.53 [1.07, 2.20]). Among time 1 ever smokers, both tobacco marketing receptivity and exposure to movie smoking predicted higher levels of time 2 smoking [2.17 (1.78, 2.63) and 1.62 (1.18, 2.23), respectively], and the two estimates were not significantly different. Conclusions In this longitudinal study, exposure to movie smoking was a stronger predictor of smoking initiation than tobacco marketing receptivity, which was more common among ever smokers. The results suggest that entertainment media smoking should be emphasized in programs aimed at preventing onset, and both exposures should be emphasized in programs aimed at experimental smokers.

In this pilot study, respondent-driven sampling was used to sample 156 Muslim college students. Waterpipe smoking was common (44.3%). Leading motivations to smoke were social and perceived low tobacco harm. Independent risk factors among the Muslim students were perception that friends and other students smoked, and ever drank alcohol. Personal belief that waterpipe smoking is prohibited in Islam was not significant. This pilot suggests that Muslim students are at high risk for waterpipe smoking and more definitive studies are needed. PMID:24797155

  14. Influence of tobacco smoke on the elemental composition of indoor particles of different sizes

    Tobacco smoking is one of the greatest sources of indoor inhalable (PM 10) particles. In the past, the studies conducted on indoor particulates were mostly related to PM 10, however in the last decade respirable particles (PM 2.5) and even smaller particles (PM 1) began to be more important as they penetrate deeper in the respiratory system, causing severe health effects. Therefore, more information on fine particles is needed. Aiming to evaluate the impact of tobacco smoke on public health, this work evaluates the influence of tobacco smoke on the characteristics of PM 10, PM 2.5, and PM 1 considering concentration and elemental composition. Samples were collected at sites influenced by tobacco smoke, as well as at reference sites, using low-volume samplers; the element analyses were performed by proton induced X-ray emission (PIXE); Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Se, Br, Cd, I, Ba, La, Ce and Pb were quantified. At the sites influenced by tobacco smoke concentrations were 270-560% higher for PM 10 and 320-680% higher for PM 2.5 than at reference sites. Tobacco smoke increased the total concentrations of five carcinogenic elements (Cr, Ni, As, Cd and Pb) 1100-2400% for PM 10 and 840-2200% for PM 2.5. The elements associated with tobacco smoke (S, K, Cr, Ni, Zn, As, Cd and Pb) were predominantly present in the fine fraction; the elements mostly originating from building erosion (Mg, Al, Si and Ca) predominantly occurred in the coarse particles. The analysis of enrichment factors confirmed that tobacco smoking mainly influenced the composition of the fine fraction of particles; as these smaller particles have a strong influence on health, these conclusions are relevant for the development of strategies to protect public health.

    Though several studies have found a positive relationship between exposure to tobacco advertising and/or promotional marketing and smoking status among youth, few have examined these relationships specifically for youth of Mexican origin. The current analysis examines the relationship between perceived exposure to pro-tobacco messages and progression through the smoking continuum from trying to repeated use in a cohort of Mexican origin youth ages 14-19. Data were collected via personal in-home interviews at two time points-in 2008-2009 and 2010-2011 (N = 942). Smoking status, exposure to pro-tobacco messages from five major media sources, demographic variables and established risk factors for adolescent smoking were measured at both waves. Data were analyzed using Pearson's Chi square tests, ANOVA, and multinomial logistic regression. Adolescent perception of the number of pro-tobacco messages seen in 2008-2009 was unrelated to smoking less than one cigarette assessed in 2010-2011. However, having seen a higher number of pro-tobacco messages was significantly associated with being more likely to have smoked more than one cigarette (OR = 1.21; 95% CI 1.03-1.42) controlling for demographic factors and known psychosocial risk factors of smoking behavior. Results suggest that the more pro-tobacco messages Mexican origin youth are able to recall, the further their progression through the smoking trajectory a year later. These youth are clearly susceptible to pro-tobacco messaging, and our results underscore the need to restrict all forms of messaging that promote tobacco use. PMID:23584711

    This paper is part of a collection that identifies research priorities that will help guide the efforts of the U.S. Food and Drug Administration (FDA) as it regulates tobacco products. This paper examines the major provisions related to tobacco product advertising, marketing, sales, and distribution included in Public Law 111-31, the "Family Smoking Prevention and Tobacco Control Act". This paper covers 5 areas related to (a) marketing regulations (e.g., ban on color and imagery in ads, ban on nontobacco gifts with purchase); (b) granting FDA authority over the sale, distribution, accessibility, advertising, and promotion of tobacco and lifting state preemption over advertising; (c) remote tobacco sales (mail order and Internet); (d) prevention of illicit and cross-border trade; and (e) noncompliant export products. Each of the 5 sections of this paper provides a description and brief history of regulation, what is known about this regulatory strategy, and research opportunities. PMID:21690316

    A retrospective study was planned in the Hrault (Mediterranean) region of France where bladder cancer mortality and incidence rates are high. In the present paper, variations in bladder cancer risk according to various smoking-related variables, in particular time of exposure and type of tobacco, are examined. This case-control study with 219 male incident cases and 794 male population controls randomized from electoral rolls was carried out in 1987-89. Trained interviewers obtained information on demographics, dietary habits (coffee, alcohol, artificial sweeteners, vegetables, spices, etc.), occupational exposures and detailed history of tobacco smoking (average number of cigarettes per day, number of years of smoking, age at which they began and/or quitted smoking, use of filter-tip and type of tobacco). The odds ratio (OR) for cigarette smokers versus non-smokers was greater than 5. Results for number of cigarettes daily, duration of smoking and lifetime smoking showed a highly significant dose-response relationship, which was confirmed when these variables were treated as continuous in a logistic regression model. Eighty-eight percent of the smokers used black tobacco. Quitting smoking did not result in a significant reduction in bladder cancer risk. Higher risks were associated with starting to smoke at an early age (OR before age 13 versus after age 21 = 3.42; 95% CI 1.07-10.9) and with black tobacco smoking (OR black versus blond = 1.63; 95% CI 0.73-3.64). Results suggest that black tobacco may be more harmful than blond tobacco and may have an early non-reversible role in bladder carcinogenesis. PMID:7859861

    Smoking conventional lit-end cigarettes results in exposure of nonsmokers to potentially harmful cigarette smoke constituents present in environmental tobacco smoke (ETS) generated by sidestream smoke emissions and exhaled mainstream smoke. ETS constituent concentrations generated by a conventional lit-end cigarette and a newly developed electrically heated cigarette smoking system (EHCSS) that produces only mainstream smoke and no sidestream smoke emissions were investigated in simulated "office" and "hospitality" environments with different levels of baseline indoor air quality. Smoking the EHCSS (International Organisation for Standardization yields: 5 mg tar, 0.3 mg nicotine, and 0.6 mg carbon monoxide) in simulated indoor environments resulted in significant reductions in ETS constituent concentrations compared to when smoking a representative lit-end cigarette (Marlboro: 6 mg tar, 0.5 mg nicotine, and 7 mg carbon monoxide). In direct comparisons, 24 of 29 measured smoke constituents (83%) showed mean reductions of greater than 90%, and 5 smoke constituents (17%) showed mean reductions between 80% and 90%. Gas-vapor phase ETS markers (nicotine and 3-ethenylpyridine) were reduced by an average of 97% (range 94-99%). Total respirable suspended particles, determined by online particle measurements and as gravimetric respirable suspended particles, were reduced by 90% (range 82-100%). The mean and standard deviation of the reduction of all constituents was 94 +/- 4%, indicating that smoking the new EHCSS in simulated "office" and "hospitality" indoor environments resulted in substantial reductions of ETS constituents in indoor air.

    Background Tobacco smoke contains carcinogens known to damage somatic and germ cells. We investigated the effect tobacco smoke on the risk of childhood acute lymphoblastic leukemia (ALL) and myeloid leukemia (AML), especially subtypes of pre-natal origin like ALL with translocation t(12;21) or high-hyperdiploidy (5167 chromosomes). Methods We collected information on exposures to tobacco smoking before conception, during pregnancy, and after birth in 767 ALL cases, 135 AML cases, and 1,139 controls (19962008). Among cases, chromosome translocations, deletions, or aneuploidy were identified by conventional karyotype and fluorescence in-situ hybridization. Results Multivariable regression analyses for ALL and AML overall showed no definite evidence of associations with self-reported (yes/no) parental prenatal active smoking and child's passive smoking. However, children with history of paternal prenatal smoking combined with postnatal passive smoking had a 1.5-fold increased risk of ALL (95% CI: 1.012.23), compared to those without smoking history (ORs for pre- or postnatal smoking only were close to one). This joint effect was seen for B-cell precursor ALL with t(12;21) (OR=2.08; 95% CI: 1.044.16), but not high hyperdiploid B-cell ALL. Similarly, child's passive smoking was associated with an elevated risk of AML with chromosome structural changes (OR=2.76; 95% CI: 1.017.58), but not aneuploidy. Conclusions our data suggest that exposure to tobacco smoking before were associated with increased risks of childhood ALL and AML; and risks varied by timing of exposure (before and/or after birth) and cytogenetic subtype, based on imprecise estimates. Impact Parents should limit exposures to tobacco smoke before and after the child's birth. PMID:23853208

    Raising the price of tobacco products has been shown to reduce tobacco consumption in the United States and other high-income countries, and evidence of this impact has been growing for low- and middle-income countries as well. Turkey is a middle-income country surveyed by the Global Adult Tobacco Survey (GATS) twice in a 4-year period, in 2008 and 2012. During this time, the country introduced a policy raising its Special Consumption Tax on Tobacco and implemented a comprehensive tobacco control program banning smoking in public places, banning advertising, and introducing graphic health warnings. The higher tobacco tax took effect in early 2010, allowing sufficient time for subsequent changes in prices and smoking to be observed by the time of the 2012 GATS. This report uses data from GATS Turkey to examine how cigarette prices changed after the 2010 tax increase, describe the temporally associated changes in smoking prevalence, and learn whether this smoking prevalence changed more in some demographic groups than others. From 2008 to 2012, the average price paid for cigarettes increased by 42.1%, cigarettes became less affordable, and smoking prevalence decreased by 14.6%. The largest reduction in smoking was observed among persons with lower socioeconomic status (SES), highlighting the potential role of tax policy in reducing health disparities across socioeconomic groups.

    This study investigated the associations of youth cigarette smoking with tobacco outlet densities and proximity of tobacco outlets to youth homes and schools across different buffers in 45 midsized California communities. The sample comprised 832 youths who were surveyed about their smoking behaviors. Inclusion criteria included both home and school addresses within city boundaries. Observations in the 45 cities were conducted to document addresses of tobacco outlets. City- and buffer-level demographics were obtained and negative binomial regression analyses with cluster robust standard errors were conducted. All models were adjusted for youth gender, age, and race. Greater densities of tobacco outlets within both a 0.75 and 1-mile buffer of youth homes were associated with higher smoking frequency. Neither tobacco outlet densities around schools nor distance to the nearest tobacco outlet from home or school were associated with youths past-30-day smoking frequency. Lower population density and percent of African Americans in areas around homes and lower percent of unemployed in areas around schools were associated with greater smoking frequency. Results of this study suggest that restricting outlet density within at least 1-mile surrounding residential areas will help to reduce youth smoking. PMID:24254336

    Objectives Environmental tobacco smoke (ETS) exposure has been associated with adverse health outcomes. Our goal was to determine if ETS exposure changed between 19982000 and 20032005 among participants in the population-based Epidemiology of Hearing Loss Study. Methods ETS exposure was ascertained using a cotinine-validated questionnaire at the 5-year (19982000) and 10-year follow-up examinations (20032005). Non-smoking participants with data from both visits were included (n=1898; ages 5396 years at 5-yr follow-up). McNemars test was used to test differences in ETS exposure overall and in three settings: home, work, and social settings. Generalized estimating equations (GEE) were used for multivariate logistic regression models of exposure. Results The proportion of nonsmokers with no or little ETS exposure increased from 80% to 88% (p<0.0001). The percent living in a home with no indoor smokers increased from 94% to 97% (p<0.0001). The percent reporting no exposure at work increased from 91% to 95% (p<0.0001). The percent reporting the lowest frequency of social exposure increased from 65% to 77% (p<0.0001). In the GEE model, age was inversely associated with exposure (Odds Ratio (OR) per 5 yr=0.80, 95% Confidence Interval (95% CI)=0.76, 0.86), as was education (OR for college vs

    Objectives Waterpipe smoking using sweetened, flavoured tobacco products has become a widespread global phenomenon. In this paper, we review chemical, physical and biological properties of waterpipe smoke. Data sources Peer-reviewed publications indexed in major databases between 1991 and 2014. Search keywords included a combination of: waterpipe, narghile, hookah, shisha along with names of chemical compounds and classes of compounds, in addition to terms commonly used in cellular biology and aerosol sizing. Study selection The search was limited to articles published in English which reported novel data on waterpipe tobacco smoke (WTS) toxicant content, biological activity or particle size and which met various criteria for analytical rigour including: method specificity and selectivity, precision, accuracy and recovery, linearity, range, and stability. Data extraction Multiple researchers reviewed the reports and collectively agreed on which data were pertinent for inclusion. Data synthesis Waterpipe smoke contains significant concentrations of toxicants thought to cause dependence, heart disease, lung disease and cancer in cigarette smokers, and includes 27 known or suspected carcinogens. Waterpipe smoke is a respirable aerosol that induces cellular responses associated with pulmonary and arterial diseases. Except nicotine, smoke generated using tobacco-free preparations marketed for ‘health conscious’ users contains the same or greater doses of toxicants, with the same cellular effects as conventional products. Toxicant yield data from the analytical laboratory are consistent with studies of exposure biomarkers in waterpipe users. Conclusions A sufficient evidence base exists to support public health interventions that highlight the fact that WTS presents a serious inhalation hazard. PMID:25666550

    Objective: To describe how the tobacco industry used the "accommodation" message to mount an aggressive and effective worldwide campaign to recruit hospitality associations, such as restaurant associations, to serve as the tobacco industry's surrogate in fighting against smoke-free environments. Methods: We analysed tobacco industry documents publicly available on the internet as a result of litigation in the USA. Documents were accessed between January and November 2001. Results: The tobacco industry, led by Philip Morris, made financial contributions to existing hospitality associations or, when it did not find an association willing to work for tobacco interests, created its own "association" in order to prevent the growth of smoke-free environments. The industry also used hospitality associations as a vehicle for programmes promoting "accommodation" of smokers and non-smokers, which ignore the health risks of second hand smoke for employees and patrons of hospitality venues. Conclusion: Through the myth of lost profits, the tobacco industry has fooled the hospitality industry into embracing expensive ventilation equipment, while in reality 100% smoke-free laws have been shown to have no effect on business revenues, or even to improve them. The tobacco industry has effectively turned the hospitality industry into its de facto lobbying arm on clean indoor air. Public health advocates need to understand that, with rare exceptions, when they talk to organised restaurant associations they are effectively talking to the tobacco industry and must act accordingly.

    Objectives. We investigated tobacco companies’ knowledge about concurrent use of tobacco and alcohol, their marketing strategies linking cigarettes with alcohol, and the benefits tobacco companies sought from these marketing activities. Methods. We performed systematic searches on previously secret tobacco industry documents, and we summarized the themes and contexts of relevant search results. Results. Tobacco company research confirmed the association between tobacco use and alcohol use. Tobacco companies explored promotional strategies linking cigarettes and alcohol, such as jointly sponsoring special events with alcohol companies to lower the cost of sponsorships, increase consumer appeal, reinforce brand identity, and generate increased cigarette sales. They also pursued promotions that tied cigarette sales to alcohol purchases, and cigarette promotional events frequently featured alcohol discounts or encouraged alcohol use. Conclusions. Tobacco companies’ numerous marketing strategies linking cigarettes with alcohol may have reinforced the use of both substances. Because using tobacco and alcohol together makes it harder to quit smoking, policies prohibiting tobacco sales and promotion in establishments where alcohol is served and sold might mitigate this effect. Smoking cessation programs should address the effect that alcohol consumption has on tobacco use. PMID:21852637

    Despite 50+ years of public health efforts to reduce smoking rates in the United States, approximately one-fifth of the adults living in this country continue to smoke cigarettes. Previous studies have examined smokers’ risk perceptions of cigarette smoking, as well as the perceived benefits of quitting smoking. Less research has focused on the perceived benefits of smoking among current cigarette smokers. The latter is the main focus of the present paper. Questionnaire-based interviews were conducted with a community-based sample of 485 adult current cigarette smokers recruited from the Atlanta, Georgia, metropolitan area between 2004 and 2007. Active and passive recruiting approaches were used, along with a targeted sampling strategy. Results revealed that most current cigarette smokers perceive themselves to experience benefits as a result of their cigarette use, including (among others) increased relaxation, diminished nervousness in social situations, enjoyment of the taste of cigarettes when smoking, and greater enjoyment of parties when smoking. Perceiving benefits from cigarette smoking was associated with a variety of tobacco use measures, such as smoking more cigarettes, an increased likelihood of chain smoking, and overall negative attitude toward quitting smoking, among others. Several factors were associated with the extent to which smokers perceived themselves to benefit from their tobacco use, including education attainment, the age of first purchasing cigarettes, the proportion of friends who smoked, hiding smoking from others, being internally-oriented regarding locus of control, and self-esteem.

    Water-pipe smoking (WPS) is a major type of smoking in Middle Eastern countries and is increasing in popularity in Western countries and is perceived as relatively safe. However, data on the adverse cardiovascular effects of WPS are scarce. Here, we assessed the cardiovascular effects of nose-only exposure to mainstream WPS generated by commercially available honey-flavored "moasel" tobacco in BALB/c mice. The duration of the session was 30 min/day for 1 mo. Control mice were exposed to air. WPS caused a significant increase of systolic blood pressure (SBP) in vivo (+13 mmHg) and plasma concentrations of IL-6 (+30%) but not that of TNF-?. Heart concentrations of IL-6 (+184%) and TNF-? (+54%) were significantly increased by WPS. Concentrations of ROS (+95%) and lipid peroxidation (+27%) were significantly increased, whereas those of GSH were decreased (-21%). WPS significantly shortened the thrombotic occlusion time in pial arterioles (-46%) and venules (40%). Plasma von Willebrand factor concentrations were significantly increased (+14%) by WPS. Erythrocyte numbers (+15%) and hematocrit (+17%) were significantly increased. Blood samples taken from mice exposed to WPS and exposed to ADP showed significant platelet aggregation compared with air-exposed mice. WPS caused a significant shortening of activated partial thromboplastin time (-45%) and prothrombin time (-13%). We conclude that 1-mo nose-only exposure to WPS increased SBP and caused cardiac inflammation, oxidative stress, and prothrombotic events. Our findings provide plausible elucidation that WPS is injurious to the cardiovascular system. PMID:23812392

    The 16-City Study analyzed for gas-phase environmental tobacco smoke (ETS) constituents (nicotine, 3-ethenyl pyridine [3-EP], and myosmine) and for particulate-phase constituents (respirable particulate matter [RSP], ultraviolet-absorbing particulate matter [UVPM], fluorescing particulate matter [FPM], scopoletin, and solanesol). In this second of three articles, the authors discuss the merits of each constituent as a marker for ETS and report pair-wise comparisons of the markers. Neither nicotine nor UVPM were good predictors for RSP. However, nicotine and UVPM were good qualitative predictors of each other. Nicotine was correlated with other gas-phase constituents. Comparisons between UVPM and other particulate-phase constituents were performed. Its relation with FPM was excellent, with UVPM approximately 1 1/2 times FPM. The correlation between UVPM and solanesol was good, but the relationship between the two was not linear. The relation between UVPM and scopoletin was not good, largely because of noise in the scopoletin measures around its limit of detection. The authors considered the relation between nicotine and saliva cotinine, a metabolite of nicotine. The two were highly correlated on the group level.

    Demonstration of a dose-response relationship for environmental tobacco smoke (ETS) is an important indication of causality. Central to the analysis and interpretation of dose-response relations as described in epidemiological studies is the relationship between dose and exposure. It must be recognized that in studies of ETS the authors have only surrogate measures of dose, and these surrogate measures (based on exposure) are imperfect. The question-based measures of ETS exposure generally have not been standardized, may have limited validity and reliability, and cannot comprehensively describe total ETS exposure, exposure to individual ETS components, nor doses of biologically relevant agents at target sites. Nevertheless, useful data have been yielded in epidemiologic studies linking ETS exposure to increased respiratory infection and symptoms, reduced lung growth in children, and increased lung cancer in nonsmoking adults. The more consistent exposure-response data for studies on acute health in children may reflect the greater difficulty in measuring exposure in studies of chronic health in adults.

  13. Influences of Tobacco Advertising Exposure and Conduct Problems on Smoking Behaviors Among Adolescent Males and Females

    PubMed Central

    2014-01-01

    Introduction: Adolescents with conduct problems are more likely to smoke, and tobacco advertising exposure may exacerbate this risk. Males excess risk for conduct problems and females susceptibility to advertising suggest gender-specific pathways to smoking. We investigated the associations between gender, conduct problems, and lifetime smoking and adolescents exposure to tobacco advertising, and we examined prospective relationships with smoking behaviors. Methods: Adolescents completed baseline (20012004; n = 541) and 5-year follow-up (20072009; n =320) interviews for a family study of smoking risk. Baseline interviews assessed conduct problems and tobacco advertising exposure; smoking behavior was assessed at both timepoints. Generalized linear models analyzed gender differences in the relationship between conduct problems, advertising exposure, and smoking behavior at baseline and longitudinally. Results: At baseline, among males, conduct problems were associated with greater advertising exposure independent of demographics and lifetime smoking. Among females at baseline, conduct problems were associated with greater advertising exposure only among never-smokers after adjusting for demographics. In longitudinal analyses, baseline advertising exposure predicted subsequent smoking initiation (i.e., smoking their first cigarette between baseline and follow-up) for females but not for males. Baseline conduct problems predicted current (i.e., daily or weekly) smoking at follow-up for all adolescents in adjusted models. Conclusions: The findings of this study reinforce that conduct problems are a strong predictor of subsequent current smoking for all adolescents and reveal important differences between adolescent males and females in the relationship between conduct problems, tobacco advertising behavior, and smoking behavior. The findings suggest gender-specific preventive interventions targeting advertising exposure may be warranted. PMID:24590388

    The objective of this research project was to improve the basis for estimating environmental tobacco smoke (ETS) exposures in a variety of indoor environments. The research utilized experiments conducted in both laboratory and ''real-world'' buildings to (1) study the transport of ETS species from room to room, (2) examine the viability of using various chemical markers as tracers for ETS, and (3) to evaluate to what extent re-emission of ETS components from indoor surfaces might add to the ETS exposure estimates. A three-room environmental chamber was used to examine multi-zone transport and behavior of ETS and its tracers. One room (simulating a smoker's living room) was extensively conditioned with ETS, while a corridor and a second room (simulating a child's bedroom) remained smoking-free. A series of 5 sets of replicate experiments were conducted under different door opening and flow configurations: sealed, leaky, slightly ajar, wide open, and under forced air-flow conditions. When the doors between the rooms were slightly ajar the particles dispersed into the other rooms, eventually reaching the same concentration. The particle size distribution took the same form in each room, although the total numbers of particles in each room depended on the door configurations. The particle number size distribution moved towards somewhat larger particles as the ETS aged. We also successfully modeled the inter-room transport of ETS particles from first principles--using size fractionated particle emission factors, predicted deposition rates, and thermal temperature gradient driven inter-room flows, This validation improved our understanding of bulk inter-room ETS particle transport. Four chemical tracers were examined: ultraviolet-absorbing particulate matter (UVPM), fluorescent particulate matter (FPM), nicotine and solanesol. Both (UVPM) and (FPM) traced the transport of ETS particles into the non-smoking areas. Nicotine, on the other hand, quickly adsorbed on unconditioned surfaces so that nicotine concentrations in these rooms remained very low, even during smoking episodes. These findings suggest that using nicotine as a tracer of ETS particle concentrations may yield misleading concentration and/or exposure estimates. The results of the solanesol analyses were compromised, apparently by exposure to light during collection (lights in the chambers were always on during the experiments). This may mean that the use of solanesol as a tracer is impractical in ''real-world'' conditions. In the final phase of the project we conducted measurements of ETS particles and tracers in three residences occupied by smokers who had joined a smoking cessation program. As a pilot study, its objective was to improve our understanding of how ETS aerosols are transported in a small number of homes (and thus, whether limiting smoking to certain areas has an effect on ETS exposures in other parts of the building). As with the chamber studies, we examined whether measurements of various chemical tracers, such as nicotine, solanesol, FPM and UVPM, could be used to accurately predict ETS concentrations and potential exposures in ''real-world'' settings, as has been suggested by several authors. The ultimate goal of these efforts, and a future larger multiple house study, is to improve the basis for estimating ETS exposures to the general public. Because we only studied three houses no firm conclusions can be developed from our data. However, the results for the ETS tracers are essentially the same as those for the chamber experiments. The use of nicotine was problematic as a marker for ETS exposure. In the smoking areas of the homes, nicotine appeared to be a suitable indicator; however in the non-smoking regions, nicotine behavior was very inconsistent. The other tracers, UVPM and FPM, provided a better basis for estimating ETS exposures in the ''real world''. The use of solanesol was compromised--as it had been in the chamber experiments.

    The idea of inhaling smoke from cigarettes is historically new, actually less than a century old. Consumption of tobacco has changed from chewing tobacco and pipe smoking to smoking cigarettes; smokeless tobaccos are growing tremendously in popularity. The modern smoker is confronted with a highly engineered, complex composite of specially designed paper, tobacco, tobacco additives, and a panoply of filters, a far cry from the hollow reed Columbus saw. Tobacco has been glibly referred to as a form of revenge by native Indians. There is little similarity between ceremonial use of tobacco by the Indians and the robotic puffing of the modern smoker. The real culprit is the cigarette. PMID:3276460

    Tobacco-constituent biomarkers are metabolites of specific compounds present in tobacco or tobacco smoke. Highly reliable analytic methods, based mainly on mass spectrometry, have been developed for quantitation of these biomarkers in both urine and blood specimens. There is substantial interindividual variation in smoking-related lung cancer risk that is determined in part by individual variability in the uptake and metabolism of tobacco smoke carcinogens. Thus, by incorporating these biomarkers in epidemiologic studies, we can potentially obtain a more valid and precise measure of in vivo carcinogen dose than by using self-reported smoking history, ultimately improving the estimation of smoking-related lung cancer risk. Indeed, we have demonstrated this by using a prospective study design comparing biomarker levels in urine samples collected from smokers many years before their development of cancer versus those in their smoking counterparts without a cancer diagnosis. The following urinary metabolites were associated with lung cancer risk, independent of smoking intensity and duration: cotinine plus its glucuronide, a biomarker of nicotine uptake; 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and its glucuronides (total NNAL), a biomarker of the tobacco carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK); and r-1-,t-2,3,c-4-tetrahydroxy-1,2,3,4-tetrahydrophenanthrene (PheT), a biomarker of polycyclic aromatic hydrocarbons (PAH). These results provide several possible new directions for using tobacco smoke-constituent biomarkers in lung cancer prevention, including improved lung cancer risk assessment, intermediate outcome determination in prevention trials, and regulation of tobacco products.

    The mutagenicity of particulate matter concentrated from environmental tobacco smoke (ETS) from a prototype cigarette that primarily heats tobacco was compared to that of four popular commercially available cigarettes that burn tobacco. ETS was generated by six individuals simultaneously smoking 1 cigarette each in a 20-min time period in a 45 m3 environmental chamber operated in the static mode (without ventilation). Respirable suspended particles (RSP) were collected on polytetrafluoroethylene (PTFE) filters at a flow rate of 3 LPM for 120 min. Less ETS-RSP (86-90%) was emitted by the prototype tobacco-heating cigarette than by the tobacco-burning cigarettes. RSP was extracted from the filters by sequential sonication in acetone and dichloromethane. The acetone extract was dried under nitrogen and the dichloromethane filtrate was added and then dried to obtain ETS-RSP for testing. Mutagenicity was assessed in the microsuspension modification of the Ames Salmonella/microsome assay with strains TA98 and YG1024 in the presence of 5% S9 metabolic activation. The results show that the mutagenic activity of RSP from the prototype cigarette was reduced by 75-83% on a per-mg basis when compared to the commercially available cigarettes and was reduced by 96-98% when calculated as revertants/m3 air under identical smoking conditions.

    Objective Research on the effects of state-level tobacco control policies targeted at youth has been mixed, with little on the effects of these policies and youth smoking cessation. This study explored the association between state-level tobacco control policies and youth smoking cessation behaviors from 1991–2006. Methods The study design was a population-based, nested survey of students within states. Study participants were 8th, 10th, and 12th graders who reported smoking “regularly in the past” or “regularly now” from the Monitoring the Future study. Main cessation outcome measures were: any quit attempt; want to quit; non-continuation of smoking; and discontinuation of smoking. Results Results showed that cigarette price was positively associated with a majority of cessation-related measures among high school smokers. Strength of sales to minors’ laws was also associated with adolescent non-continuation of smoking among 10th and 12th graders. Conclusions Findings suggest that increasing cigarette price can encourage cessation-related behaviors among high school smokers. Evidence-based policy, such as tax increases on tobacco products, should be included as an important part of comprehensive tobacco control policy, which can have a positive effect on decreasing smoking prevalence and increasing smoking cessation among youth.

    Raised serum IgE levels were found in a high proportion of rats that had been exposed to tobacco smoke twice daily 5 days a week for 8 wk in a Dontenville-type smoking machine. Levels above 1 ng/ml of IgE were found in nine of 20 animals exposed to cigarette smoke and in five of 20 rats exposed to smoke from cigarettes with 1.45% phenylmethyloxidiazole added for possible protection against the effects of the smoke. None of the 20 control rats exhibited similarly increased serum IgE. Exposure to tobacco smoke did not significantly affect the serum concentrations of IgM and IgG. The development of specific IgE and IgG antibodies was also influenced by tobacco smoke exposure. Rats exposed to ovalbumin aerosol developed increased levels of IgG and IgE antibodies, whereas no effect on the development of antibody titers was found in rats immunized by the subcutaneous route. This study demonstrates that exposure to tobacco smoke increases serum IgE levels and enhances sensitization via the airways by a local effect, thus supporting the mucosal theory of atopy.

  4. Sources, Sinks and Cycling of Acetyl Radicals in Tobacco Smoke: A Model for Biomass Burning Chemistry

    NASA Astrophysics Data System (ADS)

    Hu, N.; Green, S. A.

    2012-12-01

    Smoke near the source of biomass burning contains high concentrations of reactive compounds, with NO and CH3CHO concentrations four to six orders of magnitude higher than those in the ambient atmosphere. Tobacco smoke represents a special case of biomass burning that is quite reproducible in the lab and may elucidate early processes in smoke from other sources. The origins, identities, and reactions of radical species in tobacco smoke are not well understood, despite decades of study on the concentrations and toxicities of the relatively stable compounds in smoke. We propose that reactions of NO2 and aldehydes are a primary source for transient free radicals in tobacco smoke, which contrasts with the long-surmised mechanism of reaction between NO2 and dienes. The objective of this study was to investigate the sources, sinks and cycling of acetyl radical in tobacco smoke. Experimentally, the production of acetyl radical was demonstrated both in tobacco smoke and in a simplified mixture of air combined with NO and acetaldehyde, both of which are significant components of smoke. Acetyl radicals were trapped from the gas phase using 3-amino-2, 2, 5, 5-tetramethyl-proxyl (3AP) on solid support to form stable 3AP adducts for later analysis by high performance liquid chromatography (HPLC), mass spectrometry/tandem mass spectrometry (MS-MS/MS) and liquid chromatography-mass spectrometry (LC-MS). The dynamic nature of radical cycling in smoke makes it impossible to define a fixed concentration of radical species; 2.15×e13-3.18×e14 molecules/cm3 of acetyl radicals were measured from different cigarette samples and smoking conditions. Matlab was employed to simulate reactions of NO, NO2, O2, and a simplified set of organic compounds known to be present in smoke, with a special emphasis on acetaldehyde and the acetyl radical. The NO2/acetaldehyde mechanism initiates a cascade of chain reactions, which accounts for the most prevalent known carbon-centered radicals found in tobacco smoke, and pathways for formation of OH and peroxyl species. Tobacco smoke provides a new perspective of radical generation in a relatively well-defined biomass burning process.

    The present study examined tobacco use, secondhand smoke exposure and related knowledge, attitudes and behaviors among Asian Americans in the Delaware Valley of Pennsylvania and New Jersey, and the relationship between acculturation and smoking, social influence patterns on smoking, and stages of change of smoking among Asian subgroups. Study sample was 1174 Chinese, Koreans, Vietnamese, Cambodians, and other Asians. Findings revealed mean age of initiation to be 18.3, 40% ever and 30% current users. Significant differences were reflected in smoking by gender, ethnicity, educational level, marital and employment status. While knowledge and attitudes about smoking and secondhand smoke were associated with these variables, ethnic pride and smoking status played significant roles. Fathers and brothers had greater social influence on young male smoking behavior; smoking friends had influence on both genders. Stages of change of smoking and acculturation impact on smoking varied with gender, age, and time living in the U.S. Findings provide comprehensive insights into tobacco use and related KAB among Asian Americans that reflect the need for developing culturally appropriate programs for this underserved population.

    Polycyclic aromatic hydrocarbons (PAHs) were measured in mainstream and sidestream tobacco smoke from 14 commercial brands of cigarettes purchased in Italy during 2001-2002. The PAHs detected in smoke and analysed with HPLC and a fluorimetric detector were: fluoranthene, pyrene, benzo[a]anthracene, chrysene, benzo[a]pyrene, benzo[b] fluoranthene, benzo[k] fluoranthene, benzo[g,h,i]perylene and dibenzo[a,h]anthracene. The PAH levels in mainstream smoke from different cigarette brands obtained using an official smoking machine varied by about threefold (from 118 to 374 ng per cigarette for total PAHs and from 23.5 to 100 ng per cigarette for carcinogenic PAHs). Total PAH levels in mainstream smoke were correlated with tar content (r = 0.615, P < 0.05, n = 14). Total PAH content in sidestream smoke, measured by collection of all the smoke produced by a lit cigarette in a glass chamber, was about tenfold higher compared with mainstream smoke. The PAH content in sidestream smoke was relatively uniform (2.3-3.9 and 0.49-1.21 micro g per cigarette for total and carcinogenic PAHs, respectively) and was not correlated with tar content. These results indicate that cigarette manufacturing and filter characteristics influence the PAH composition of mainstream smoke, but have no effect on the PAH content in sidestream smoke, which is the main determinant of smokers' and non-smokers' exposure to PAHs in environmental tobacco smoke.

    This study examined an assumption held by many smoking prevention programs that social skills can affect the onset of tobacco smoking. Data from 129 sixth graders were used to predict smoking behavior 15 months later in seventh grade. Five skill variables emerged as the best predictors of future smoking. By analyzing discriminant scores based on individual levels of social skills, the investigators were able to accurately classify 80% of the students surveyed as smokers or nonsmokers. Measures of social skills accounted for 29% of the variation in adolescent smoking behavior. PMID:3846044

    Objective Lesbian, gay, bisexual, and transgender (LGBT) people have significantly higher smoking prevalence than heterosexual people in the United States. The reasons for this disparity remain unclear. Tobacco use in movies has a substantial influence on tobacco use behaviours, particularly among youth. Yet, no research has examined tobacco use in movies for LGBT audiences or containing LGBT characters. Methods We identified 81 U.S. movies from 2000–2011 with a theatre release and with LGBT themes or characters. We then selected a random sample of these movies (n = 45) for quantitative content analysis to examine the proportion of movies with depictions of tobacco use and the number of occurrences of tobacco use. Results Tobacco use was depicted in 87%(95% confidence interval [CI]: 80%–94%) of movies with an average of 4 occurrences of tobacco use per hour (95% CI: 3–5). Only 15% (95% CI: 8%–23%) of movies and 3% of all depictions of tobacco use conveyed any harms of tobacco use. Conclusions Viewers of movies with LGBT themes or characters are exposed, on average, to one depiction of tobacco use for every 15 minutes of movie run-time. As a major component of the entertainment media environment, movies may contribute to smoking among LGBT people. PMID:24277775

    Methods: Data for this study come from tobacco industry documents contained in the Youth and Marketing database created by the Roswell Park Cancer Institute and available through http:// roswell.tobaccodocuments.org, supplemented with documents obtained from http://www.tobaccodocuments.org. Results: Tobacco company documents provide clear evidence on the impact of cigarette prices on cigarette smoking, describing how tax related and other price increases lead to significant reductions in smoking, particularly among young persons. This information was very important in developing the industry's pricing strategies, including the development of lower price branded generics and the pass through of cigarette excise tax increases, and in developing a variety of price related marketing efforts, including multi-pack discounts, couponing, and others. Conclusions: Pricing and price related promotions are among the most important marketing tools employed by tobacco companies. Future tobacco control efforts that aim to raise prices and limit price related marketing efforts are likely to be important in achieving reductions in tobacco use and the public health toll caused by tobacco.

All available materials, including confidential reports regarding research, lobbying, and internal memoranda exchanged between the tobacco industry representatives, tobacco industry lawyers, and key players in Latin America. Results: In Latin America, Philip Morris International and British American Tobacco, working through the law firm Covington & Burling, developed a network of well placed physicians and scientists through their "Latin Project" to generate scientific arguments minimising secondhand smoke as a health hazard, produce low estimates of exposure, and to lobby against smoke-free workplaces and public places. The tobacco industry's role was not disclosed. Conclusions: The strategies used by the industry have been successful in hindering development of public health programmes on secondhand smoke. Latin American health professionals need to be aware of this industry involvement and must take steps to counter it to halt the tobacco epidemic in Latin America. PMID:12432156

    In the domain of the essential trace elements, the role of selenium is extremely important. As one of the volatile elements it can be partly absorbed through the pulmonary system during smoking and transported to different organs of the body. Thus a knowledge of its concentration levels in various sorts of tobacco and in the smoke of commercial cigarettes, as well as in the same type of cigarettes from plants treated with selenium, is of interest for various research fields. The purpose of this contribution is to present reliable quantitative data on selenium contents in tobacco, soil, and main stream cigarette smoke, obtained by destructive neutron activation analysis.

    Objective To analyse the statements given by tobacco industry defence witnesses during trial testimonies and depositions in second?hand smoke cases and in parallel, to review criticisms of epidemiology in industry?funded publications in order to identify strategies for discrediting epidemiologic evidence on passive smoking health effects. Methods A collection of depositions and trial testimony transcripts from tobacco industry?related lawsuits filed in the United States during the 1990s, was compiled and indexed by the Tobacco Deposition and Trial Testimony Archive (DATTA). Statements in DATTA made by expert witnesses representing the tobacco industry relating to the health effects of passive smoking were identified and reviewed. Industry?supported publications within the peer?reviewed literature were also examined for statements on exposure misclassification, meta?analysis, and confounding. Results The witnesses challenged causation of adverse health effects of passive smoking by citing limitations of epidemiologic research, raising methodological and statistical issues, and disputing biological plausibility. Though not often cited directly by the witnesses, the defence tactics mirrored the strategies used in industry?funded reports in the peer?reviewed literature. Conclusion The tobacco industry attempted to redirect the focus and dialogue related to the epidemiologic evidence on passive smoking. This approach, used by industry experts in trial testimony and depositions, placed bias as a certain alternative to causation of diseases related to passive smoking and proposed an unachievable standard for establishing the mechanism of disease.

    Tobacco smoke contains thousands of ingredients, including those causing serious respiratory and cardiovascular diseases, and which are carcinogens or cancer promoters. Plants and plant products have antioxidant properties and have a protective role against cancer defined as chemoprevention. This paper presents an overview of published experiments on the protective effect against tobacco smoke or its by compounds and raw materials of natural origin, from plants mainly. These were: N-acetyl-L-cysteine, vitamin C, A and E, beta-carotene, lycopene, andrographolide, farnesol, resveratrol, marigold and tea. These studies were carried out on experimental animals or animal or human cells, which were exposed to cigarette smoke or its extract, or components of tobacco smoke. The studies have shown that the mentioned compounds and raw materials have a protective effect against the harmful effects of tobacco smoke. Mechanisms of action were different--the increase of the level of glutathione and antioxidant enzymes, prevention DNA strand breakage and lipid peroxidation, increased accumulation of the transcription factor Nrf2 that controls the expression of antioxidant genes. Authors frequently suggested that the investigated compounds and the materials may have similar protective effects against tobacco smoke in humans. PMID:26731873

    Background Environmental factors such as inhaled pollutants like cigarette smoke may play a significant role in diseases of the upper airway including chronic rhinosinusitis (CRS). The objectives of this review are to summarize prior studies that describe the correlation between active smoking and second-hand smoke (SHS) on CRS. We also review the pathophysiologic effects of cigarette smoke on sinonasal mucosa and discuss its impact on surgical outcomes of endoscopic sinus surgery (ESS). Methods A literature search was conducted with the PUBMED database using the terms sinusitis or rhinosinusitis and smoking. Additional search terms of nasal epithelial and smoke were used to find articles which discussed pathophysiologic effects of tobacco smoke while second-hand smoke was added to identify articles analyzing the correlation of SHS and CRS. Finally endoscopic sinus surgery and outcomes were linked to smoking to find articles that analyzed the impact of smoking on surgical results. Results 204 articles were identified in the initial search. An additional 72 articles were reviewed for their relevance to the pathophysiologic effects of tobacco smoke while 31 papers were analyzed to determine the correlation of SHS and CRS. Twenty-nine papers were reviewed to analyze the impact of smoking on surgical results. Conclusion There is clear evidence in the literature that cigarette smoke, either through active smoking or passive exposure to SHS, contributes to CRS. Recent prospective studies suggest that active smoking is not a contraindication to ESS while the impact of smoking volume and long-term smoking after ESS has not been sufficiently evaluated.

    Secondhand smoke (SHS) has been associated with a variety of adverse health outcomes in nonsmokers, including emphysema (a chronic obstructive pulmonary disease). One way to detect SHS exposure is to measure the concentration of cotinine, the primary metabolite of nicotine, in bodily fluids. We have developed a method for cotinine analysis by combining micellar electrokinetic chromatography with enrichment techniques. We employed the method to measure cotinine concentrations in serum samples of mice exposed to tobacco smoke for 12 or 24 weeks and found that it was 3.1-fold or 4.8-fold higher than those exposed to room air for the same period. Further, we investigated the morphological changes in lungs of mice and observed tobacco smoke induced emphysema. Our results indicate that the method can be used to measure cotinine and there is an association between the serum cotinine concentration and tobacco smoke-induced emphysema in mice.

We have developed a method for cotinine analysis by combining micellar electrokinetic chromatography with enrichment techniques. We employed the method to measure cotinine concentrations in serum samples of mice exposed to tobacco smoke for 12 or 24 weeks and found that it was 3.1-fold or 4.8-fold higher than those exposed to room air for the same period. Further, we investigated the morphological changes in lungs of mice and observed tobacco smoke induced emphysema. Our results indicate that the method can be used to measure cotinine and there is an association between the serum cotinine concentration and tobacco smoke-induced emphysema in mice. PMID:24463700

    In Germany, smoking rates among women have been slightly declining since 2003. However, smoking rates among young women and girls are high and are reaching the smoking rates of their male counterparts. Only about half of pregnant smokers below the age of 25 stop smoking. Women and girls with low education and low level jobs, those who are unemployed, as well as single parents have the highest smoking rates. The tobacco industry promotes smoking behavior of women and girls through marketing campaigns, thus, systematically counteracting smoking prevention activities. Within the framework of the annual conference 2008 of the Federal Drug Commissioner on the theme of "Women and Smoking", recommendations for a gender-specific tobacco control policy in Germany were developed. The main demands relate to the necessity of a targeted policy approach which takes into account the needs and life circumstances of women and girls, the development of integrated prevention programs for pregnant women, improved medical and preventive care, the involvement of women from the media and culture, from health professions and politics to promote a smoke-free culture, gender-specific research, and the improvement of tobacco control legislation. FACT (Frauen aktiv contra Tabak e.V.) actively supports the implementation of these policy recommendations. PMID:20069267

    Background: It has been conformed that active smoking is an established risk factor for pancreatic cancer, but the role of environmental tobacco smok (passive smoking) in pancreatic cancer remains unclear. We intended to study the relationship between passive smoking and pancreatic cancer. Methods: From Oct. 1991 to Sep. 2014, A hospital-based case-control study on pancreatic cancer was conducted from the inpatient of five hospitals. 1076 cases pancreatic cancer patients. History of exposure to environmental tobacco smoke was assessed through questionnaires. Relative risks (RR) and 95% confidence intervals (CI) were estimated using Cox proportional hazards models. Results: During 23 years of follow-up (1991-2014), 1076 patients were diagnosed with pancreatic cancer (686 men and 390 women). Compared to paternal smoking (RR, 0.97; 95% CI, 0.77-1.21; P = 0.084), maternal smoking significantly increased the risk of pancreatic cancer (R, 1.56; 95% CI, 1.13-1.98; P = 0.018). Although the risk associated with maternal smoking remained elevated compared to the never smokers (RR, 1.49; 95% CI, 1.07-2.27), there was no statistical significance. Conclusions: The positive association with maternal smoking suggests that environmental tobacco smoke, potentially in utero or in early life, may be associated with pancreatic cancer. PMID:26629212

    Clean indoor air (CIA) ordinances in Toledo, Ohio, and Bowling Green, Ohio, regulate smoking in restaurants to protect patrons and employees. Yet complete protection is questionable because the ordinances allow for smoking in certain dining sections. Two restaurants were studied in each city, one smoking and one nonsmoking. Levels of contaminants related to environmental tobacco smoke (ETS)--determined by personal and area air monitoring-in the nonsmoking restaurants were comparable to levels in a control environment. However, levels of ETS-related contaminants in the smoking restaurants, including designated nonsmoking sections, were significantly higher than levels in the control environment. ETS-related contamination of the nonsmoking sections in the smoking restaurants is attributable to direct openings between the smoking and nonsmoking sections. Reasonable protection of employees and patrons against ETS-related contaminants requires strict enforcement of CIA ordinances. Full protection is achievable only with 100% smoke-free policies.

    We propose that in utero exposure to tobacco smoke products places a newborn at risk for persistent pulmonary hypertension of the newborn (PPHN). To test this hypothesis, infants with PPHN were identified. Healthy newborns of similar ethnicity were identified as a comparison group. Cord blood cotinine concentrations and maternal questionnaires were obtained. The number of women exposed to tobacco smoke in each group ascertained by questionnaire was borderline significantly different (38.7% vs. 20.5%; p = 0.080). However, more PPHN infants had detectable cotinine in their cord blood (64.5% vs. 28.2%; p = 0.002), and the median cotinine concentrations were significantly higher (5.2 ng/ml vs. 2 ng/ml; p = 0.051) than the comparison infants. Among infants delivered to nonsmoking women, more PPHN infants had detectable cotinine (50% vs. 19%; p = 0.015), and the cotinine concentrations were higher (3.5 ng/ml vs. 1.65 ng/ml; p = 0.022) than the comparison group. We conclude that active and passive smoking during pregnancy is a risk factor for PPHN. Therefore, we recommend that pregnant women cease smoking and avoid environmental tobacco smoke.

    A coupling between a cigarette smoking simulator and a time-of-flight mass spectrometer was constructed to allow investigation of tobacco smoke formation under simulated burning conditions. The cigarette smoking simulator is designed to burn a sample in close approximation to the conditions experienced by a lit cigarette. The apparatus also permits conditions outside those of normal cigarette burning to be investigated for mechanistic understanding purposes. It allows control of parameters such as smouldering and puff temperatures, as well as combustion rate and puffing volume. In this study, the system enabled examination of the effects of "smoking" a cigarette under a nitrogen atmosphere. Time-of-flight mass spectrometry combined with a soft ionisation technique is expedient to analyse complex mixtures such as tobacco smoke with a high time resolution. The objective of the study was to separate pyrolysis from combustion processes to reveal the formation mechanism of several selected toxicants. A purposely designed adapter, with no measurable dead volume or memory effects, enables the analysis of pyrolysis and combustion gases from tobacco and tobacco products (e.g. 3R4F reference cigarette) with minimum aging. The combined system demonstrates clear distinctions between smoke composition found under air and nitrogen smoking atmospheres based on the corresponding mass spectra and visualisations using principal component analysis.

    Because the morbidity and mortality from adult asthma have been increasing, the identification of modifiable environmental exposures that exacerbate asthma has become a priority. Limited evidence suggests that exposure to environmental tobacco smoke (ETS) may adversely affect adults with asthma. To study the effects of ETS better, we developed a survey instrument to measure ETS exposure in a cohort of adults with asthma living in northern California, where public indoor smoking is limited. To validate this survey instrument, we used a passive badge monitor that measures actual exposure to ambient nicotine, a direct and specific measure of ETS. In this validation study, we recruited 50 subjects from an ongoing longitudinal asthma cohort study who had a positive screening question for ETS exposure or potential exposure. Each subject wore a passive nicotine badge monitor for 7 days. After the personal monitoring period, we readministered the ETS exposure survey instrument. Based on the survey, self-reported total ETS exposure duration ranged from 0 to 70 hr during the previous 7 days. Based on the upper-range boundary, bars or nightclubs (55 hr) and the home (50 hr) were the sites associated with greatest maximal self-reported exposure. As measured by the personal nicotine badge monitors, the overall median 7-day nicotine concentration was 0.03 microg/m(3) (25th-75th interquartile range 0-3.69 microg/m(3)). Measured nicotine concentrations were highest among persons who reported home exposure (median 0.61 microg/m(3)), followed by work exposure (0.03 microg/m(3)), other (outdoor) exposure (0.025 microg/m(3)), and no exposure (0 microg/m(3); p = 0.03). The Spearman rank correlation coefficient between self-reported ETS exposure duration and directly measured personal nicotine concentration during the same 7-day period was 0.47, supporting the survey's validity (p = 0.0006). Compared to persons with no measured exposure, lower-level [odds ratio (OR) 1.9; 95% confidence interval (CI), 0.4-8.8] and higher-level ETS exposures (OR 6.8; 95% CI, 1.4-32.3) were associated with increased risk of respiratory symptoms. A brief, validated survey instrument can be used to assess ETS exposure among adults with asthma, even with low levels of exposure. This instrument could be a valuable tool for studying the effect of ETS exposure on adult asthma health outcomes. PMID:11564616

    Tobacco smoke is one of the greatest sources of indoor particles, which has been linked with serious health effects. Consequently, there has been a widespread interest in analysing tobacco related indoor particulate matter (PM). Nevertheless, the majority of performed studies focused on bulk chemical composition of tobacco related PM, but the knowledge of individual tobacco smoke particles is still limited. Therefore, more information on PM should be provided, namely concerning morphological and chemical characterisation of individual particles. Aiming to further understand the impact of tobacco smoke on human health, this work studied the influence of tobacco smoke on chemical and morphological characteristics of PM 10 and PM 2.5, collected at one site influenced by smoking and at one reference (non-smoking) site. Chemical and morphological characteristics of 4000 individual particles were determined by Scanning Electron Microscopy (SEM) combined with X-ray microanalysis (by Energy Dispersive Spectrometer - EDS). Cluster analysis (CA) was used to classify different particle groups that occurred in PM, aiming the identification of the respective emission sources. The results showed that tobacco smoke influenced the characteristics of both fine and coarse particles, this influence being stronger for fine fraction. The abundance of particles associated with tobacco smoke was 27% and 5% for PM 2.5 and PM 2.5-10, respectively; as expected, those particles were not identified in PM 2.5 and PM 2.5-10 of the reference (non-smoking) site. The results showed that at both sites PM was also influenced by outdoor sources. For PM 2.5-10, outdoor particles essentially originated from natural sources accounting for 35% and 15% at the smoking and reference sites, respectively. For PM 2.5, outdoor particles account for 38% and 29% at the smoking and reference sites, respectively; these particles showed considerable contribution (13% and 17%) from anthropogenic sources (mainly from traffic emissions). In general SEM-EDS showed to be a useful technique to complement characterisation of PM 2.5 and PM 2.5-10, and to identify the respective emission sources.

  9. The effects of smoking status and ventilation on environmental tobacco smoke concentrations in public areas of UK pubs and bars

    NASA Astrophysics Data System (ADS)

    Carrington, Joanna; Watson, Adrian F. R.; Gee, Ivan L.

    UK public houses generally allow smoking to occur and consequently customer ETS exposure can take place. To address this, in 1999 the UK Government and the hospitality industry initiated the Public Places Charter (PPC) to increase non-smoking facilities and provide better ventilation in public houses. A study involving 60 UK pubs, located in Greater Manchester, was conducted to investigate the effects of smoking area status and ventilation on ETS concentrations. ETS markers RSP, UVPM, FPM, SolPM and nicotine were sampled and analysed using established methodologies. ETS marker concentrations were significantly higher ( P < 0.05) in the smoking areas compared to the non-smoking areas of pubs that contained both smoking and non-smoking sections. Median concentrations of RSP and nicotine were reduced by 18% and 68%, respectively, in non-smoking areas. UVPM, FPM and SolPM median concentrations were reduced by 27%, 34% and 39%, demonstrating the increased tobacco-specificity of the particulate markers and the impact of non-smoking areas. Levels of particulate phase ETS markers were also found to be higher in the smoking sections of pubs that allowed smoking throughout compared to the smoking sections of pubs with other areas where smoking was prohibited. The presence of a non-smoking section has the effect of reducing concentrations even in the smoking areas. This may be caused by migration of smoke into the non-smoking section thereby diluting the smoking area or by smokers tending to avoid pubs with non-smoking areas thus reducing source strengths in the smoking areas of these pubs. Nicotine concentrations were not found to be significantly different in smoking areas of the two types of establishment indicating that nicotine is not as mobile in these environments and tends to remain in the smoking areas. This result, together with the much higher reductions in nicotine concentrations between smoking and non-smoking areas compared to other markers, suggests that nicotine is not the most suitable marker to use in these environments as an indicator of the effectiveness of tobacco control policies. The use of ventilation systems (sophisticated HVAC systems and extractor fans in either the on or off mode) did not have a significant effect ( P > 0.05) on ETS marker concentrations in either the smoking or non-smoking areas. The PPC aims to reduce non-smoking customers' exposure through segregation and ventilation and provide customer choice though appropriate signs. This study indicates that although ETS levels are lower in non-smoking sections and signs will assist customers in reducing their exposure, some exposure will still occur because ETS was detected in non-smoking areas. Existing ventilation provision was not effective in reducing exposure and signs advertising ventilated premises may be misleading to customers. Improvements in the design and management of ventilation systems in pubs and bars are required to reduce customer exposure to ETS, if the aims of the PPC are to be met.

    This study demonstrates the ability of tar isolated from environmental tobacco smoke (ETS) to nick DNA in mammalian cells. Solutions of ETS tar behave similarly to aqueous solutions of cigarette tar from mainstream smoke. Both solutions contain the tar semiquinone radical, and this radical associates with the DNA in viable rat alveolar macrophages. Solutions of tar from ETS cause single-strand DNA breaks in rat thymocytes in proportion to the amount of tar present, until a plateau is reached. ETS tar solutions, like mainstream tar solutions, produce hydrogen peroxide. Hydrogen peroxide appears to be an essential component of the mechanism by which both ETS tar and mainstream tar cause DNA damage in rat thymocytes, as catalase substantially protects against DNA damage. Glutathione also protects against DNA nicking by both ETS and mainstream tar solutions by scavenging radicals and/or oxidants. The chelator diethylenetriamine pentaacetic acid also provides partial (40%) protection. The studies demonstrate that the water-soluble components of ETS tar can enter cells, associate with, and then nick DNA. Images Figure 1. Figure 2. Figure 3. Figure 4. Figure 5. PMID:9644196

    Accurate identification and quantification of the secondhand tobacco smoke (SHS) that drifts between multiunit homes (MUHs) is essential for assessing resident exposure and health risk. We collected 24 gaseous and particle measurements over 6-9 day monitoring periods in five nonsmoking MUHs with reported SHS intrusion problems. Nicotine tracer sampling showed evidence of SHS intrusion in all five homes during the monitoring period; logistic regression and chemical mass balance (CMB) analysis enabled identification and quantification of some of the precise periods of SHS entry. Logistic regression models identified SHS in eight periods when residents complained of SHS odor, and CMB provided estimates of SHS magnitude in six of these eight periods. Both approaches properly identified or apportioned all six cooking periods used as no-SHS controls. Finally, both approaches enabled identification and/or apportionment of suspected SHS in five additional periods when residents did not report smelling smoke. The time resolution of this methodology goes beyond sampling methods involving single tracers (such as nicotine), enabling the precise identification of the magnitude and duration of SHS intrusion, which is essential for accurate assessment of human exposure.

    Background In spite of the negative health effects of waterpipe tobacco smoking, its use is becoming more common. The objective of this study is to systematically review the medical literature for motives, beliefs and attitudes towards waterpipe tobacco smoking. Methods We electronically searched MEDLINE, EMBASE, and the ISI the Web of Science in January 2012. We included both quantitative and qualitative studies. We selected studies and abstracted data using standard systematic review methodology. We synthesized data qualitatively. Results We included 58 papers reporting on 56 studies. The main motives for waterpipe tobacco smoking were socializing, relaxation, pleasure and entertainment. Peer pressure, fashion, and curiosity were additional motives for university and school students while expression of cultural identity was an additional motive for people in the Middle East and for people of Middle Eastern descent in Western countries. Awareness of the potential health hazards of waterpipe smoking was common across settings. Most but not all studies found that the majority of people perceived waterpipe smoking as less harmful than cigarette smoking. Waterpipe smoking was generally socially acceptable and more acceptable than cigarette smoking in general. In Middle Eastern societies, it was particularly more acceptable for womens use compared to cigarette use. A majority perceived waterpipe smoking as less addictive than cigarette smoking. While users were confident in their ability to quit waterpipe smoking at any time, willingness to quit varied across settings. Conclusions Socializing, relaxation, pleasure and entertainment were the main motives for waterpipe use. While waterpipe users were aware of the health hazards of waterpipe smoking, they perceived it as less harmful, less addictive and more socially acceptable than cigarette smoking and were confident about their ability to quit.

    Primary care providers should be aware of two new developments in nicotine addiction and smoking cessation: 1) the emergence of a novel nicotine delivery system known as the electronic (e-) cigarette; and 2) new reports of residual environmental nicotine and other biopersistent toxicants found in cigarette smoke, recently described as thirdhand smoke. The purpose of this article is to provide a clinician-friendly introduction to these two emerging issues so that clinicians are well prepared to counsel smokers about newly recognized health concerns relevant to tobacco use. E-cigarettes are battery powered devices that convert nicotine into a vapor that can be inhaled. The World Health Organization has termed these devices electronic nicotine delivery systems (ENDS). The vapors from ENDS are complex mixtures of chemicals, not pure nicotine. It is unknown whether inhalation of the complex mixture of chemicals found in ENDS vapors is safe. There is no evidence that e-cigarettes are effective treatment for nicotine addiction. ENDS are not approved as smoking cessation devices. Primary care givers should anticipate being questioned by patients about the advisability of using e-cigarettes as a smoking cessation device. The term thirdhand smoke first appeared in the medical literature in 2009 when investigators introduced the term to describe residual tobacco smoke contamination that remains after the cigarette is extinguished. Thirdhand smoke is a hazardous exposure resulting from cigarette smoke residue that accumulates in cars, homes, and other indoor spaces. Tobacco-derived toxicants can react to form potent cancer causing compounds. Exposure to thirdhand smoke can occur through the skin, by breathing, and by ingestion long after smoke has cleared from a room. Counseling patients about the hazards of thirdhand smoke may provide additional motivation to quit smoking. PMID:21475626

    Background Costs of tobacco?related disease can be useful evidence to support tobacco control. In Hong Kong we now have locally derived data on the risks of smoking, including passive smoking. Aim To estimate the health?related costs of tobacco from both active and passive smoking. Methods Using local data, we estimated active and passive smoking?attributable mortality, hospital admissions, outpatient, emergency and general practitioner visits for adults and children, use of nursing homes and domestic help, time lost from work due to illness and premature mortality in the productive years. Morbidity risk data were used where possible but otherwise estimates based on mortality risks were used. Utilisation was valued at unit costs or from survey data. Work time lost was valued at the median wage and an additional costing included a value of US$1.3 million for a life lost. Results In the Hong Kong population of 6.5 million in 1998, the annual value of direct medical costs, long term care and productivity loss was US$532 million for active smoking and US$156 million for passive smoking; passive smoking accounted for 23% of the total costs. Adding the value of attributable lives lost brought the annual cost to US$9.4 billion. Conclusion The health costs of tobacco use are high and represent a net loss to society. Passive smoking increases these costs by at least a quarter. This quantification of the costs of tobacco provides strong motivation for legislative action on smoke?free areas in the Asia Pacific Region and elsewhere. PMID:16565461

    National level smoke-free legislation is implemented to protect the public from exposure to second-hand tobacco smoke (SHS). The first aim of this study was to investigate how successful the smoke-free hospitality industry legislation in Ireland (March 2004), France (January 2008), the Netherlands (July 2008), and Germany (between August 2007 and July 2008) was in reducing smoking in bars. The second aim was to assess individual smokers predictors of smoking in bars post-ban. The third aim was to examine country differences in predictors and the fourth aim to examine differences between educational levels (as an indicator of socioeconomic status). This study used nationally representative samples of 3,147 adult smokers from the International Tobacco Control (ITC) Europe Surveys who were surveyed pre- and post-ban. The results reveal that while the partial smoke-free legislation in the Netherlands and Germany was effective in reducing smoking in bars (from 88% to 34% and from 87% to 44% respectively), the effectiveness was much lower than the comprehensive legislation in Ireland and France which almost completely eliminated smoking in bars (from 97% to 3% and from 84% to 3% respectively). Smokers who were more supportive of the ban, were more aware of the harm of SHS, and who had negative opinions of smoking were less likely to smoke in bars post-ban. Support for the ban was a stronger predictor in Germany. SHS harm awareness was a stronger predictor among less educated smokers in the Netherlands and Germany. The results indicate the need for strong comprehensive smoke-free legislation without exceptions. This should be accompanied by educational campaigns in which the public health rationale for the legislation is clearly explained. PMID:21497973

    2004-01-01

    The effects of 450 tobacco ingredients added to tobacco on the forty-four "Hoffmann analytes" in mainstream cigarette smoke have been determined. These analytes are believed by regulatory authorities in the USA and Canada to be relevant to smoking-related diseases. They are based on lists published by D. Hoffmann and co-workers of the American Health Foundation in New York. The ingredients comprised 431 flavours, 1 flavour/solvent, 1 solvent, 7 preservatives, 5 binders, 2 humectants, 2 process aids and 1 filler. The cigarettes containing mixtures of the ingredients were smoked using the standard ISO smoking machine conditions. The levels of the "Hoffmann analytes" in the smoke from the test cigarettes containing the ingredient mixture were compared to those from control cigarettes without the ingredients. In practice, flavouring ingredients are typically added to tobacco that also contains casing ingredients and reconstituted tobacco materials. In order to keep the tobacco mixtures as authentic as possible, three comparisons have been made in this study. These are: (a) control cigarette containing a typical US blended, cased tobacco incorporating reconstituted tobacco versus test cigarettes that had flavouring ingredients added to this tobacco; (b) control cigarette containing tobacco only versus test cigarettes with the tobacco cased and incorporating flavourings; (c) control cigarette containing tobacco only versus test cigarette incorporating additives made in an experimental sheet material. The significances of differences between the test and control cigarettes were determined using both the variability of the data on the specific occasion of the measurement, and also taking into account the long-term variability of the analytical measurements over the one-year period in which analyses were determined in the present study. This long-term variability was determined by measuring the levels of the 44 "Hoffmann analytes" in a reference cigarette on many occasions over the one-year period of this study. The ingredients were added to the experimental cigarettes at or above the maximum levels used commercially by British American Tobacco. The effect of the ingredient mixtures on total particulate matter and carbon monoxide levels in smoke was not significantly different to the control in most cases, and was never more than 10% with any ingredient mixture. It was found that, in most cases, the mixtures of flavouring ingredients (generally added in parts per million levels) had no statistically significant effect on the analyte smoke yields relative to the control cigarette. Occasionally with some of the mixtures, both increases and decreases were observed for some smoke analyte levels relative to the control cigarette. These differences were generally up to about 15% with the mixtures containing flavouring ingredients. The significance of many of the differences was not present when the long-term variability of the analytical methodology was taken into account. For the test cigarettes with ingredient mixtures containing casing ingredients, there were again no significant changes in smoke analyte levels in most cases. Those changes that were observed are as follows. Decreases in smoke levels were observed with some ingredient mixtures for most of the tobacco specific nitrosamines (up to 24%), NO(x), most of the phenols (up to 34%), benzo[a]pyrene, and some of the aromatic amines and miscellaneous organic compounds on the "Hoffmann list". Increases were observed for some test cigarettes in smoke ammonia, HCN, formaldehyde and lead levels (up to 24%). The significance of the ammonia and lead increases was not present when the long-term variability of the analytical methodology was taken into account. The yields of some carbonyl compounds in smoke were increased in one comparison with an additives mixture containing cellulosic components; in particular, formaldehyde was increased by 68%. This was the largest single change seen in any smoke analyte level in this study. These carbonyls are

    Biochemically and pathologically, there is strong evidence for both atopic and nonatopic airway sensitization, hyperresponsiveness, and inflammation as a consequence of exposure to tobacco mainstream or sidestream smoke particulate. There is growing evidence for the relation between exposure to mainstream and sidestream smoke and diseases resulting from reactive oxidant challenge and inflammation directly as a consequence of the combined activity of neutrophils, macrophages, dendritic cells, eosinophils, basophils, as a humoral immunological consequence of sensitization, and that the metal components of the particulate play a role in adjuvant effects. As an end consequence, carcinogenicity is a known outcome of chronic inflammation. Smokeless tobacco has been evaluated by the IARC as a group 1 carcinogen. Of the many harmful constituents in smokeless tobacco, oral tissue metallothionein gradients suggest that metals contribute to the toxicity from smokeless tobacco use and possibly sensitization. This work reviews and examines work on probable contributions of toxic metals from tobacco and smoke to pathology observed as a consequence of smoking and the use of smokeless tobacco. PMID:21799956

    Introduction: Exposure to environmental tobacco smoke (ETS) is defined as a human cancerogen class A, due daily exposure is responsible for health hazards consider as almost equal as smoking of tobacco. Goal: Monitoring of exposure of school children to ETS as indicator of enforcement of ban of smoking in public places as tobacco control measure in the Federation of BiH. Methods: Analysis of surveys findings performed in the Federation of BiH in period 2008-2013, with particular focus on ETS exposure in school children. Results: A survey findings indicates decrease of exposure to ETS in school children ate home from 79.0% in 2008 to 62.1% in 2013, as well decrease of exposure to ETS in public places from 85.0% in 2008 to 59.8% in 2013. However, 65.8% of school children in the Federation of BiH are daily expose to ETS in school premises and only 54.6% of school children have been taught in school about health consequences of tobacco smoke. Over three quarter of school children or 80.1% are in favor of ban of smoking in public places. Conclusions: Exposure to ETS in school children considers as significant evidence for more efficient enforcement of tobacco control legislation in the Federation of BiH. PMID:25648163

    We conducted cross-sectional, multicenter studies in HIV-positive young women and men to assess metabolic and morphologic complications from tobacco smoking in 372 behaviorally infected HIV-positive youth, aged 14-25 years. Measurements included self-reported tobacco use, fasting lipids, glucose, fat distribution, and bone mineral density (BMD; dual-energy X-ray absorptiometry scans). Overall, 144 (38.7%) self-reported smoking tobacco and 69 (47.9%) of these reported smoking greater than five cigarettes per day. Smokers versus nonsmokers had lower mean total cholesterol (146.0 versus 156.1?mg/dL; P < 0.01) and lower mean total body fat percent (24.1% versus 27.2%, P = 0.03). There was no difference between smokers and nonsmokers in fasting glucose or BMD. There appear to be only minimal effects from tobacco smoking on markers of cardiac risk and bone health in this population of HIV-positive youth. While these smokers may not have had sufficient exposure to tobacco to detect changes in the outcome measures, given the long-term risks associated with smoking and HIV, it is critical that we encourage HIV-positive youth smokers to quit before the deleterious effects become apparent.

    Evidence has shown that factors other than the central pharmacological effects of nicotine are important in promoting smoking behavior. One such non-nicotine effect includes sensory stimulation, which may promote smoking by developing learned associations with nicotine's rewarding effects, or by constituting a rewarding experience independent of nicotine. The present study used internal tobacco industry documents to examine industry efforts to understand and manipulate stimulation of the sensory nerves by tobacco smoke, and the influence of sensory stimulation on smoker behavior. Research focused on sensory nerves of the head and neck, including the olfactory nerve, which carries flavor and odor, and the trigeminal nerve, which carries irritant information. The tobacco industry maintained a systematic research program designed to elucidate an understanding of responses of sensory nerves to nicotine and other components of tobacco smoke, and attempted to develop nicotine-like compounds that would enhance sensory responses in smokers. Industry research appeared intended to aid in the development of new products with greater consumer appeal. The potential influence of sensory response in enhancing nicotine dependence through an associative mechanism was acknowledged by the tobacco industry, but evidence for research in this area was limited. These findings add to evidence of industry manipulation of sensory factors to enhance smoking behavior and may have implications for development of more effective treatment strategies, including more "acceptable" nicotine replacement therapies.

    This study was designed to determine the prevalence of active smoking and environmental tobacco smoke (ETS) exposure among medical students in Riyadh, Saudi Arabia, and to examine their attitudes and beliefs towards tobacco control programs. The investigation was a cross-sectional study conducted during the first semester of 2013 at King Saud University School of Medicine located in Riyadh, Saudi Arabia. Invited to participate in this study were 1,789 medical students. A descriptive data analysis was performed. A total of 805 medical students completed the questionnaire. The prevalence of experimentation with cigarette smoking was 11.3%. The estimated prevalence of current smoking among the study participants was 4.7%. The majority of the students held positive attitudes toward tobacco control and approximately 93.1% of the students felt that health care professionals should be required to receive training for cessation counseling while only 36.8% of the students reported having received any training in this area. Over the study's duration 57.7% of participants reported that ETS exposure was much higher in public places, while 13.9% reported exposure at home. This investigation revealed that ETS exposure among medical students in Riyadh is at an alarmingly high rate. The data suggests a need for a more robust smoke-free policy and a commitment to greater enforcement in public places. The results of the study also demonstrate a positive attitude among participants for tobacco control. It also indicates a need for cessation counseling and training which could be incorporated into medical school curriculum. PMID:24903238

    Waterpipe smoking is becoming increasingly popular worldwide. Research has shown that cigarette smoke, in addition to hundreds of carcinogenic and otherwise toxic compounds, may also contain compounds of microbiological origin. In the present study we analyzed waterpipe smoke for some microbial compounds. Both of the two markers studied, viz 3-hydroxy fatty acids of bacterial lipopolysaccharide (LPS) and ergosterol of fungal biomass, were found in waterpipe tobacco, in amounts similar as previously found in cigarette tobacco, and in smoke. Waterpipe mainstream smoke contained on average 1800 pmol LPS and 84.4 ng ergosterol produced per session. An average concentration of 2.8 pmol/m3 of LPS was found in second hand smoke during a 1-2-h waterpipe smoking session while ergosterol was not detected; corresponding concentrations from smoking five cigarettes were 22.2 pmol/m3 of LPS and 87.5 ng/m3 of ergosterol. This is the first time that waterpipe smoking has been shown to create a bioaerosol. In the present study we also found that waterpipe smoking generated several polycyclic aromatic hydrocarbons, carbon monoxide, and high fraction of small (<200 nm) particles that may have adverse effects on human health upon inhalation.

    The aim of the present cross-sectional study was to assess tobacco use and smoking cessation among third-year dental students in southern Brazil. The Global Health Professions Student Survey questionnaire was used in eight dental schools in Rio Grande do Sul state, Brazil. Of the 663 eligible students, 576 (87%) participated. The prevalence of current smoking was 19.1% [95% confidence interval (CI): 12.9-25.3%], and 61.6% (95% CI: 54.9-68.3%) of students reported having smoked at least once in their lifetime. The prevalence of dental students who had smoked ? 100 cigarettes in their lifetime was 17.1% (95% CI: 12.5-21.7%). Being frequently exposed to other smokers at home or in other places (second-hand smoke) increased the likelihood of current smoking by two- to threefold. Approximately 6.1% (95% CI: 3.5-8.7%) of the students reported that they currently wanted to stop smoking and 7.5% (95% CI: 5.3-9.6%) had tried to stop smoking in the last year. Friends and family were the most frequent sources of help or counselling, and only a limited proportion of students received help from health professionals. Tobacco use and exposure to second-hand smoking is widespread among dental students in southern Brazil. Smoking-cessation initiatives targeting health care students are urgently needed.

    Mentally ill individuals have always smoked at high rates and continue to do so, despite public health efforts to encourage smoking cessation. In the last half century, the tobacco industry became interested in this connection, and conducted and supported psychiatric and basic science research on the mental health implications of smoking, long before most mental health professionals outside the industry investigated this issue. Initially, representatives of tobacco industry research organizations supported genetics and psychosomatic research to try to disprove findings that smoking causes lung cancer. Tobacco industry research leaders engaged with investigators because of shared priorities and interests in the brain effects of nicotine. By the 1980s, collaborative funding programs and individual company research and development teams engaged in intramural and extramural basic science studies on the neuropharmacology of nicotine. When mental health researchers outside the industry became interested in the issue of the mentally ill and smoking in the mid-1990s, they increasingly explained it in terms of a disease of nicotine addiction. Both the idea that smoking/nicotine does something positive for the mentally ill and the conclusion that it is the result of nicotine dependence have the potential to support corporate agendas (tobacco or pharmaceutical).

    Environmental tobacco smoke, inhaled by active firsthand smokers and their entourage, is associated with morbidity and mortality. Many children are passively exposed to secondhand smoke worldwide. Infants and young children account for the largest global disease burden associated with prenatal and postnatal secondhand smoke, probably due to underdeveloped neurological, immune, and respiro-circulatory systems. There is an increasingly robust association between tobacco smoke exposure, before and after birth, and executive function problems in children, adding to current and future disease burden estimates in public health. This review summarizes research advancements which address the link between environmental tobacco smoke and the development of attention deficits and hyperactive behavior, both as symptoms and as part of a mental health disorder in childhood. The multiple effects of tobacco smoke inhalation are best understood in terms of disruptions in normative processes involving cellular communication, structural development, and epigenetic influences which have the potential to become intergenerational. It is concluded that public health efforts be directed toward increasing parental awareness and compliance with existing guidelines that recommend no safe level of exposure. PMID:23545330

    The aim of this study was to estimate the effect of exposure to secondhand tobacco smoke on the incidence of lung adenocarcinoma in situ/minimally invasive adenocarcinoma (AIS/MIA). Data from seven case-control studies participating in the International Lung Cancer Consortium (ILCCO) were pooled, resulting in 625 cases of AIS/MIA and 7,403 controls, of whom 170 cases and 3,035 controls were never smokers. Unconditional logistic regression was used to estimate adjusted ORs (ORadj) and 95% confidence intervals (CI), controlling for age, sex, race, smoking status (ever/never), and pack-years of smoking. Study center was included in the models as a random-effects intercept term. Ever versus never exposure to secondhand tobacco smoke was positively associated with AIS/MIA incidence in all subjects (ORadj = 1.48; 95% CI, 1.14-1.93) and in never smokers (ORadj = 1.45; 95% CI, 1.00-2.12). There was, however, appreciable heterogeneity of ORadj across studies (P = 0.01), and the pooled estimates were largely influenced by one large study (40% of all cases and 30% of all controls). These findings provide weak evidence for an effect of secondhand tobacco smoke exposure on AIS/MIA incidence. Further studies are needed to assess the impact of secondhand tobacco smoke exposure using the newly recommended classification of subtypes of lung adenocarcinoma. PMID:26503035

    A survey of environmental tobacco smoke (ETS) controls in California office buildings was carried out to obtain information of the type and distribution of ETS controls in office buildings and to evaluate the effectiveness of various ETS controls. A total of 118 smoking areas in 111 county and city buildings were inspected to collect information on the type of ETS controls. Only 31% of the smoking areas inspected were physically separated from nonsmoking areas with full floor-to-true-ceiling walls, 25% exhausted air to the outside, and 38% did not recirculate air to non-smoking areas. A total of 23 smoking areas and their adjacent non-smoking areas in 21 buildings were monitored for nicotine and fluorescent particulate matter (FPM). A tracer gas, sulfur hexafluoride (SF6), was released in smoking areas to measure the air leakage from smoking areas to adjacent non-smoking areas. The measurements of nicotine, FPM, and SF6 have shown large variations of the effectiveness of ETS controls. The least effective type of smoking area studied were open areas with no physical barriers between smoking and nonsmoking areas, no exhaust to the outside and no return air separation. On the contrary, smoking rooms with three ETS controls (i.e., physical separation, exhaust to outside, and no air recirculation) were the most effective design in containing ETS within smoking areas.

    Introduction: Smoke-free homes can help protect children from tobacco smoke exposure (TSE). The objective of this study was to conduct a meta-analysis to quantify effects of interventions on changes in tobacco smoke pollution in the home, as measured by air nicotine and particulate matter (PM). Methods: We searched MEDLINE, PubMed, Web of Science, PsycINFO, and Embase. We included controlled trials of interventions which aimed to help parents protect children from tobacco smoke exposure. Two reviewers identified relevant studies, and three reviewers extracted data. Results: Seven studies were identified. Interventions improved tobacco smoke air pollution in homes as assessed by nicotine or PM. (6 studies, N = 681, p = 0.02). Analyses of air nicotine and PM separately also showed some benefit (Air nicotine: 4 studies, N = 421, p = 0.08; PM: 3 studies, N = 340, p = 0.02). Despite improvements, tobacco smoke pollution was present in homes in all studies at follow-up. Conclusions: Interventions designed to protect children from tobacco smoke are effective in reducing tobacco smoke pollution (as assessed by air nicotine or PM) in homes, but contamination remains. The persistence of significant pollution levels in homes after individual level intervention may signal the need for other population and regulatory measures to help reduce and eliminate childhood tobacco smoke exposure.

    Introduction In vitro toxicology studies of tobacco and tobacco smoke have been used to understand why tobacco use causes cancer and to assess the toxicological impact of tobacco product design changes. The need for toxicology studies has been heightened given that the FDA’s newly granted authority over tobacco products requires mandating performance standards for tobacco products and evaluate manufacturers’ health claims. The goal of this review is to critically evaluate in vitro toxicology methods related to cancer for assessing tobacco products and to identify related research gaps. Methods PubMed database searches were used to identify tobacco-related in vitro toxicology studies published since 1980. Articles published prior to 1980 with high relevance also were identified. The data was compiled to examine: 1) goals of the study; 2) methods for collecting test substances; 3) experimental designs; 4) toxicological endpoints, and; 5) relevance to cancer risk. Results A variety of in vitro assays are available to assess tobacco and tobacco smoke that address different modes of action, mostly using non-human cell models. Smokeless tobacco products perform poorly in these assays. While reliable as a screening tool for qualitative assessments, the available in vitro assays have been poorly validated for quantitative comparisons of different products. Assay batteries have not been developed, although they exist for non-tobacco assessments. Extrapolating data from in vitro studies to human risks remains hypothetical. Conclusions In vitro toxicology methods are useful for screening toxicity, but better methods are needed for today’s context of regulation and evaluation of health claims. PMID:19959677

    Tobacco smoking using a waterpipe (narghile, hookah, shisha) has become a global epidemic. Unlike cigarette smoking, little is known about the health effects of waterpipe use. One acute effect of cigarette smoke inhalation is dysfunction in autonomic regulation of the cardiac cycle, as indicated by reduction in heart rate variability (HRV). Reduced HRV is implicated in adverse cardiovascular health outcomes, and is associated with inhalation exposure-induced oxidative stress. Using a 32 participant cross-over study design, we investigated toxicant exposure and effects of waterpipe smoking on heart rate variability when, under controlled conditions, participants smoked a tobacco-based and a tobacco-free waterpipe product promoted as an alternative for health-conscious users. Outcome measures included HRV, exhaled breath carbon monoxide (CO), plasma nicotine, and puff topography, which were measured at times prior to, during, and after smoking. We found that waterpipe use acutely decreased HRV (p<0.01 for all measures), independent of product smoked. Plasma nicotine, blood pressure, and heart rate increased only with the tobacco-based product (p<0.01), while CO increased with both products (p<0.01). More smoke was inhaled during tobacco-free product use, potentially reflecting attempted regulation of nicotine intake. The data thus indicate that waterpipe smoking acutely compromises cardiac autonomic function, and does so through exposure to smoke constituents other than nicotine. PMID:23059956

  12. Quantitative effects of tobacco smoking exposure on the maternal-fetal circulation

    2011-01-01

    Background Despite the existence of various published studies regarding the effects of tobacco smoking on pregnancy, and especially in regards to placental blood flow and vascular resistance, some points still require clarification. In addition, the amount of damage due to tobacco smoking exposure that occurs has not been quantified by objective means. In this study, we looked for a possible association between flow resistance indices of several arteries and the levels of urinary cotinine and the concentration of carbon monoxide in the exhaled air (COex) of both smoking and non-smoking pregnant women. We also looked for a relationship between those findings and fetal growth and birth weight. Methods In a prospective design, thirty pregnant smokers and thirty-four pregnant non-smokers were studied. The volunteers signed consent forms, completed a self-applied questionnaire and were subjected to Doppler velocimetry. Tobacco smoking exposure was quantified by subject provided information and confirmed by the measurement of urinary cotinine levels and by the concentration of carbon monoxide in the exhaled air (COex). The weight of newborns was evaluated immediately after birth. Results Comparing smoking to non-smoking pregnant women, a significant increase in the resistance index was observed in the uterine arteries (P = 0.001) and umbilical artery (P = 0.001), and a decrease in the middle cerebral artery (P = 0.450). These findings were associated with progressively higher concentrations of COex and urinary cotinine. A decrease in the birth weight was also detected (P < 0.001) in association with a progressive increase in the tobacco exposure of the pregnant woman. Conclusions In pregnant women who smoke, higher arterial resistance indices and lower birth weights were observed, and these findings were associated with increasing levels of tobacco smoking exposure. The values were significantly different when compared to those found in non-smoking pregnant women. This study contributes to the findings that smoking damage during pregnancy is dose-dependent, as demonstrated by the objective methods for measuring tobacco smoking exposure. PMID:21453488

    Serious efforts to reduce the harm caused by tobacco use throughout populations require implementation policies and interventions capable of reaching all smokers and potential smokers. While the Framework Convention on Tobacco Control promises to accelerate the adoption of comprehensive tobacco control policies throughout the world, its extensive 'optional' language provides considerable latitude for governments unwilling to implement rigorous controls. This paper examines four broad areas in which important debates and policy advances will be necessary to ensure population-wide impact of tobacco control: harm reduction; demand reduction strategies involving particularly the use of news generation in increasing the coverage of tobacco and health issues; denormalisation of tobacco use, especially among health workers in nations where use remains high; and further efforts to regulate the tobacco industry, particularly in regard to plain packaging, under-the-counter retail sales and the regulation of tobacco products.

  14. Poly-Tobacco Use Among HIV-Positive Smokers: Implications for Smoking Cessation Efforts

    2013-01-01

    Introduction: Poly-tobacco use is defined as cigarette and other tobacco consumption with either product used daily or nondaily. While concurrent use of different types of tobacco has been documented within the general population, less is known about poly-tobacco use among HIV-positive smokers and its impact on smoking cessation efforts. Objective: To characterize the profile of poly-tobacco users (PTU) in a sample of HIV-positive smokers participating in a cessation program. Methods: The study sample consisted of 474 HIV-positive smokers enrolled in a 2-group randomized controlled trial of cigarette smoking cessation comparing a cell phonebased intervention to usual care. Prevalence was determined, and risk factors for poly-tobacco use were evaluated using logistic regression. Results: In this cohort of HIV-positive cigarette smokers, 21.6% of participants were PTU, with cigars (73.4%) the most common tobacco product consumed. Among PTU, 73.5% used other form(s) of tobacco some days, and 26.5% use them every day. Perceived discrimination and unemployment were significantly associated with poly-tobacco use after adjusting for other demographic, behavioral, and psychosocial factors. Analysis showed that participants in the cell phone group (vs. usual care) were more likely to report 24-hr abstinence, both among monocigarette users (16.6% vs. 6.3%, p < .001) and PTU (18.5% vs. 0%, p < .001). Conclusion: Poly-tobacco use prevalence among adult HIV-positive smokers was considerably higher than in the general population. Special attention must be placed on concurrent use of cigarettes and cigars among HIV-positive smokers. Because PTU are a unique population less likely to succeed in brief smoking cessation interventions, effective cessation programs are needed. PMID:23907506

    Smoking prevalence is globally five times higher among men compared to women but this gap tends to decrease. Regarding health consequences of smoking, women tend to be more vulnerable than men. They are namely more at risk to present certain lung cancers and die of cardiovascular disease. While men are less prone to seek help for smoking cessation, women are less successful in their quit attempts and smoking cessation treatments are less effective among them. Interventions for smoking cessation and preventive measures tailored to gender specificities have the potential to improve management of smokers and decrease gender disparities in healthcare.

    STUDY OBJECTIVES: To document changes in smoking style around infants over time and to identify factors associated with the smoking hygiene of mothers and others. DESIGN: A population based cohort study. SETTING: Population based, involving 22% of live births in Tasmania, Australia. PARTICIPANTS: From 1 May 1988 to 30 April, 1993, 6109 infants and their mothers (89% of eligible infants) participated in the hospital and home interview of the cohort study. Infants eligible for cohort entry were those assessed at birth to be at a higher risk of SIDS. MAIN RESULTS: The overall proportion of mothers who smoked during pregnancy and postnatally did not decline. Increasing trends were found for mothers and others not smoking in the same room as baby or while holding or feeding the baby, significant over the five year period. Good smoking hygiene (mother not smoking in the same room as baby) was positively associated with--first birth (OR = 1.74 (1.30, 2.33)), low birth weight (1.69 (1.27, 2.23)), being born after 1 May 1991 (1.67 (1.33, 2.11)), and private health insurance status (1.39 (1.02, 1.90)). Good smoking hygiene was negatively associated with maternal smoking during pregnancy (0.50 (0.31, 0.80)), intention to bottle feed (0.62 (0.49, 0.78)), the level of maternal postnatal smoking, increasing numbers of smokers in the household, and parents cohabiting but unmarried. A similar analysis was conducted for other household residents who smoked. CONCLUSIONS: Changes in maternal smoking prevalence have been small. The exposure of infants to tobacco smoke postnatally has decreased significantly, although a large proportion of infants are still exposed to tobacco smoke. The identification of the above parental and infant factors associated with good smoking hygiene should be useful for health education planning. PMID:8762352

    Introduction Research indicates disparities in risky health behaviors between heterosexual and sexual minority (referred to as LGBQ; also known as lesbian, gay, bisexual, queer, and questioning) youth. Limited data are available for tobacco-use–related behaviors beyond smoking status. We compared data on tobacco age of initiation, product use, and secondhand smoke exposure between general population and LGBQ youth. Methods Data for general population youth were from the statewide, representative 2011 Missouri Youth Tobacco Survey, and data for LGBQ youth were from the 2012 Out, Proud and Healthy survey (collected at Missouri Pride Festivals). Age-adjusted Cochran-Mantel-Haenszel tests were used to examine differences between general population (N = 1,547) and LGBQ (N = 410) youth, aged 14 to 18 years. Logistic regression models identified variables associated with current smoking. Results The 2 groups differed significantly on many tobacco-use–related factors. General population youth initiated smoking at a younger age, and LGBQ youth did not catch up in smoking initiation until age 15 or 16. LGBQ youth (41.0%) soon surpassed general population youth (11.2%) in initiation and proportion of current smokers. LGBQ youth were more likely to use cigars/cigarillos, be poly-tobacco users, and be exposed to secondhand smoke (SHS) in a vehicle (for never smokers). Older age (odds ratio [OR] = 1.39, 95% confidence interval [95% CI] = 1.18–1.62), female sex (OR = 1.64, 95% CI = 1.13–2.37), LGBQ identity (OR = 3.86, 95% CI = 2.50–5.94), other tobacco product use (OR = 8.67, 95% CI = 6.01–12.51), and SHS exposure in a vehicle (OR = 5.97, 95% CI = 3.83–9.31) all significantly increased the odds of being a current smoker. Conclusion This study highlights a need for the collection of data on sexual orientation on youth tobacco surveys to address health disparities among LGBQ youth. PMID:24995655

    Tobacco smoking causes millions of cancer deaths annually. Tobacco smoke is a complex mixture of thousands of chemicals including many known animal carcinogens. Because many carcinogens from DNA adducts in target animal or human tissues, the detection of the formation of adducts using such methods as postlabeling, immunoassay, fluorescence spectroscopy, and mass spectrometry is a means of monitoring human exposure to tobacco carcinogens. Smokers are at increased risk of cancer in many organs, and studies have revealed either specific adducts related to smoking or increased levels of adducts in the lung, bronchus, larynx, bladder, cervix, and oral mucosa of smokers. In a limited number of studies, the adducts and the carcinogens responsible for them have been identified. Some studies have demonstrated higher levels of adducts in the white blood cells of smokers, while other studies indicate other sources of genotoxic agents, including diet, can contribute to the DNA damage observed in these cells.

  19. Multiwavelength absorbance of filter deposits for determination of environmental tobacco smoke and black carbon

    NASA Astrophysics Data System (ADS)

    Lawless, Phil A.; Rodes, Charles E.; Ensor, David S.

    A multiwavelength optical absorption technique has been developed for Teflon filters used for personal exposure sampling with sufficient sensitivity to allow apportionments of environmental tobacco smoke and soot (black) carbon to be made. Measurements on blank filters show that the filter material itself contributes relatively little to the total absorbance and filters from the same lot have similar characteristics; this makes retrospective analysis of filters quite feasible. Using an integrating sphere radiometer and multiple wavelengths to provide specificity, the determination of tobacco smoke and carbon with reasonable accuracy is possible on filters not characterized before exposure. This technique provides a low cost, non-destructive exposure assessment alternative to both standard thermo-gravimetric elemental carbon evaluations on quartz filters and cotinine analyses from urine or saliva samples. The method allows the same sample filter to be used for assessment of mass, carbon, and tobacco smoke without affecting the deposit.

    Tobacco use became common all over the world after discovery of Americas. Tobacco, a plant carries in its leaves an alkaloid called nicotine, which is responsible not only for several pathophysiological changes in the body but also develops tolerance to its own action with repeated use. Studies suggest that the alpha-4 beta-2 nicotine acetylcholine receptor subtype is the main receptor that mediates nicotine dependence. Nicotine acts on these receptors to facilitate neurotransmitter release (dopamine and others), producing pleasure and mood modulation. Repeated exposure to nicotine develops neuroadaptation of the receptors, resulting in tolerance to many of the effects of nicotine. Withdrawal symptoms appear on stoppage of tobacco use, which are characterized by irritability, anxiety, increased eating, dysphoria, and hedonic dysregulation, among others. Smoking is also reinforced by conditioning. Pharmacotherapies for smoking cessation should reduce withdrawal symptoms and block the reinforcing effects of nicotine obtained from smoking without causing excessive adverse effects. PMID:21267362

    Background: Tobacco smoking is the leading cause of preventable mortality. The prevalence of smoking in adolescents in high schools ranges from 23.5% to 41%, respectively. In Colombia, these figures are similar and students entering the University are exposed to initiate smoking. The purpose of this study was to establish the determinants associated with the initiation of tobacco smoking among university students. Methods: A case–control paired by sex and age study design was used. The study population was the students of a private university of Bucaramanga, Santander, Colombia. The final sample consisted of 167 cases and 314 controls randomly select undergraduate university students. Data analysis was performed using a Logistic regression model adjusted by gender and age; using the initiation of tobacco smoking as the dependent variable, and as independent variables relationship with parents, history of parental smoking, university social environment, being away from hometown, steady girlfriend/boyfriend who smokes, alcohol consumption, physical activity, and Francis Score. Results: The social environment (odds ratio [OR]: 32.70, 7.40-144.55), being away from hometown (OR: 3.06, 1.55-6.07), history of steady girlfriend/boyfriend who smoke (OR: 2.87, 1.43-5.76), a bad relationship with the father (OR: 8.01, 2.01-31.83), history of tobacco consumption of the mother (OR: 2.66, 1.37-5.17) and alcohol consumption (OR: 4.79, 1.91-12.00) appeared as determinants of initiation of tobacco smoking. As protector factors we found media advertisement (OR: 0.19, 0.05-0.71), light physical activity 2-3 times a week (OR: 0.33, 0.12-0.88), and a high result in Francis score (OR: 0.95, 0.919-0.99). Conclusions: University efforts for tobacco-free policies should focus on preventive advertisement, promoting physical activity and awareness among young students of social environmental factors that could influence their decision to start smoking tobacco.

    Background Puerto Rico (PR) has a lower smoking prevalence than the United States (14.8% vs. 21.2%, respectively); nevertheless, the five leading causes of death are associated with smoking. There is a need to implement evidence-based tobacco control strategies in PR. Objectives The Outreach Pilot Program (OPP) was designed to engage communities, health professionals, and researchers in a network to advance health promotion activities and research to increase the use of the PR Quitline (PRQ) among smokers and promoting policies in support of smoke-free workplaces. Methods Using community-based participatory research (CBPR) methods, the OPP mobilized a network of community and academic partners to implement smoking cessation activities including referrals to the PRQ, adoption of evidence-based smoking cessation programs, and promotion of smoke-free legislation. Results Eighty organizations participated in the OPP. Collaborators implemented activities that supported the promotion of the PRQ and smoke-free workplaces policy and sponsored yearly trainings, including tobacco control conferences. From 2005 to 2008, physician referrals to the PRQ increased from 2.6% to 7.2%. The number of annual smokers receiving cessation services through the PRQ also increased from 703 to 1,086. The OPP shepherded a rigorous smoke-free law through participation in the development, promotion, and implementation of the smoke-free workplaces legislation as well as the creation of the PR Tobacco Control Strategic Plan, launched in 2006. Conclusions This project demonstrates the feasibility of developing a successful and sustainable community-based outreach program model that enlists the participation of academic researchers, community organizations, and health care providers as partners to promote tobacco control.

  4. A Randomized, Controlled Community-Wide Intervention to Reduce Environmental Tobacco Smoke Exposure

    PubMed Central

    2013-01-01

    Introduction: Tobacco use in low- to middle-income countries is a major public health concern for both smokers and those exposed to environmental tobacco smoke (ETS). Egypt has made important strides in controlling tobacco use, but smoking and ETS remain highly prevalent. This randomized intervention sought to improve the target populations knowledge regarding the hazards of smoking and ETS and to change attitudes and smoking behaviors within the community and the household. Methods: In this 20052006 study in Egypts Qalyubia governorate, trained professionals visited schools, households, mosques, and health care centers in rural villages randomly selected for the intervention to discuss the adverse effects of smoking and ETS exposure and ways to reduce ones ETS exposure. Data collected in interviewer-facilitated surveys before and after the intervention period were analyzed in pairwise comparisons with data from control villages to assess the effectiveness of the intervention in achieving its aims. Results: The intervention group showed a greater increase in understanding the dangers associated with smoking cigarettes and waterpipes and became more proactive in limiting ETS exposure by asking smokers to stop, avoiding areas with ETS, and enacting smoking bans in the home. However, the intervention had little to no impact on the number of smokers and the amount of tobacco smoked. Conclusions: Results are consistent with previous studies showing that changing smokers behavior can be difficult, but community-wide efforts to reduce ETS exposure through smoking bans, education, and empowering people to ask smokers to stop are effective. The method can be generalized to other settings. PMID:23328881

    The present study describes representations about smoking and practices related to patient smoking among staff of a large public psychiatric hospital. A survey was performed using a specially designed questionnaire. The return rate was 72.4% (n = 155). A large proportion of staff recognized the importance of both smoking status and mental health for patient's well-being (46.9%), and believed that smoking cessation was possible for psychiatric patients (58.6%). However, the role of the psychiatric hospital was perceived as providing information (85.3%) and helping to diminish cigarette consumption (51%), rather than proposing smoking cessation (29.5%). Staff daily practice included reminding patients of smoking restrictions (43.9%), managing cigarettes (46.5%), and nicotine replacement therapy (24.3%). A principal component analysis of tobacco-related practices revealed two main factors (59.8% of variance): basic hospital actions (factor 1) and more specialized interventions (factor 2), which were significantly associated with higher worries about personally developing smoke-related illnesses (Spearman r = 0.38, P < 0.0001). Compared with non-smokers, smokers reported higher perceived vulnerability to develop an illness due to tobacco and a higher level of worry about this. The discussion highlights the need to redefine roles and expectancies of mental health staff, and improve training and collaboration with experts, in order to improve efficiency concerning tobacco issues.

    This paper presents the results of a smoking control programme carried out in Sant Jaume i Santa Magdalena Hospital in Matar (Barcelona, Spain) involving the entire hospital staff. The general objectives of the programme were: (1) to reduce tobacco consumption among hospital staff and (2) to create an awareness of their exemplary role as health professionals. In order to achieve these aims, different activities were carried out: lectures on the consequences of smoking; restrictions on smoking in hospital areas; and smoking cessation help for those who wished to give up smoking. To measure the effectiveness of the intervention, a survey of smoking habits and attitudes among the hospital staff was conducted before the start of the programme in 1986 and repeated two and a half years later in 1989. The population studied in both surveys (n = 298 and n = 304) was similar by sex, age, and professional status. Regarding tobacco consumption there was the same proportion of never smokers, while the percentage of current smokers was reduced by 11 between the two surveys (51 to 40%), and the ex-smokers group showed an increase (16 to 23%). These differences were significant. There was also a remarkable change in attitudes among the health professionals, especially with regard to their disposition to give advice to stop smoking. The results show a reduction of the prevalence of smoking among the hospital staff and a positive change in their attitudes towards smoking. PMID:1878621

    For over 20 years Poland has been one of the countries with the world's highest consumption of tobacco. In view of the widespread popularity of this addition, of particular importance becomes the problem of women becoming addicted to tobacco smoke. Therefore, the objective of this work was to develop and conduct preliminary surveys aimed at the determination of the scale of active and passive cigarette smoking among young women as well as the assessment of smoking on physical fitness. The research took a form of an anonymous questionnaire administered to 80 female secondary school graduates who were passing their entrance examinations to the University of Physical Education in Wroc?aw. The physical capacities were assessed on the basis of fitness tests and their results were subject to statistical analysis. One identified a significant impact of cigarette smoking on reducing the physical fitness and, in consequence, lower scores in the fitness test among smoking girls when compared to the scores of non-smoking girls (respectively 17.5+/-2.0; 21.0+/-4.5; p<0.0001). It was shown that smoking more than 10 cigarettes per day and on the fitness test day has considerably influenced their physical fitness (p<0.002; p<0.0004). Moreover, smoking women devoted less time to exercises and had a higher BMI when compared to non-smoking women. PMID:18409279

    A method was developed that utilizes a platinum trap for mercury from mainstream tobacco smoke, which represents an improvement over traditional approaches that require impingers and long sample preparation procedures. In this approach, the trapped mercury is directly released for analysis by heating the trap in a direct mercury analyzer. The method was applied to the analysis of mercury in the mainstream smoke of little cigars. The mercury levels in little cigar smoke obtained under Health Canada Intense smoking machine conditions ranged from 7.1 × 10(-3) to 1.2 × 10(-2) mg/m(3). These air mercury levels exceed the chronic inhalation minimal risk level corrected for intermittent exposure to metallic mercury (e.g., 1 or 2 h per day, 5 days per week) determined by the Agency for Toxic Substances and Disease Registry. Multivariate statistical analysis was used to assess associations between mercury levels and little cigar physical design properties. Filter ventilation was identified as the principal physical parameter influencing mercury concentrations in mainstream little cigar smoke generated under ISO machine smoking conditions. With filter ventilation blocked under Health Canada Intense smoking conditions, mercury concentrations in tobacco and puff number (smoke volume) were the primary physical parameters that influenced mainstream smoke mercury concentrations.

    Promoting tobacco control policies in rural tobacco-growing communities presents unique challenges. The purpose of this study was to assess smoke-free coalition cohesiveness in rural communities and identify coalition members perceived barriers or divisive issues that impede the development of smoke-free policies. A secondary aim was to evaluate differences in coalition cohesiveness between advocates in communities receiving stage-based, tailored policy advocacy assistance vs. those without assistance. Tobacco control advocates from 40 rural Kentucky communities were interviewed by telephone during the final wave of a 5-year longitudinal study of community readiness for smoke-free policy. On average, five health advocates per county participated in the 45-minute interview. Participants rated coalition cohesiveness as not at all cohesive, somewhat cohesive, or very cohesive, and answered one open-ended question about potentially divisive issues within their coalitions. The mean age of the 186 participants was 48.1 years (SD=13.3). The sample was predominantly female (83.6%) and Caucasian (99.5%). Divisive concerns ranged from rights issues, member characteristics, type of law, and whether or not to allow certain exemptions. Three of the divisive concerns were significantly associated with their rankings of coalition cohesiveness: raising tobacco in the community, the belief that smoke-free would adversely affect the economy, and government control. Educating coalition members on the economics of smoke-free laws and the actual economic impact on tobacco-growing may promote smoke-free coalition cohesiveness. More resources are needed to support policy advocacy in rural tobacco-growing communities as well as efforts to reduce the divisive concerns reported in this study. PMID:24338076

    Several attempts have been made to describe the relation that exists between tobacco smoke and emphysema, through different experimental models of the active smoker. Despite the negative effects that involuntarily inhaled tobacco smoke can have on the lung, no experimental model of the passive smoker has been proposed. In this study, an experimental model of the involuntary smoker is described and the following hypothesis proposed: Passive exposure to tobacco smoke produces morphological alterations in the rat lung, which are compatible with emphysema. Emphysema will be considered to have been caused when enlargement of the distal airspaces of the lung and lung tissue destruction are demonstrated. Sixty Wistar rats were used, divided into two groups: a control group and a group that was passively exposed to tobacco smoke for a period of 3 months. A morphometrical study of the lung was performed using a computerized system. To demonstrate enlargement of the distal airspaces of the lung, the following variables were quantified: alveolar chord and mean linear intercept index (Lm); tissue loss was demonstrated by means of the quantification of the variables: tissue density, internal alveolar perimeter (IAP), and wall thickness (WT). The elastic fiber was also quantified. The animals that were exposed to tobacco smoke displayed the following significant alterations (p < .05): an increase of the alveolar chord and of the Lm, a decrease of the IAP, WT, and tissue density, and a loss of the elastic component of the lung. On the basis of these findings, it is concluded that the rats that were exposed in a passive way to tobacco smoke display morphological pulmonary alterations that are compatible with the definition of emphysema.

    Objectives To understand the evolution of 20 years of tobacco industry strategies to undermine federal restrictions of smoking on aircraft in the United States. Design We searched and analysed internal tobacco industry records, public documents, and other related research. Results The industry viewed these restrictions as a serious threat to the social acceptability of smoking. Its initial efforts included covert letter?writing campaigns and lobbying of the airline industry, but with the emergence of proposals to ban smoking, the tobacco companies engaged in ever increasing efforts to forestall further restrictions. Tactics to dominate the public record became especially rigorous. The industry launched an aggressive public relations campaign that began with the promotion of industry sponsored petition drives and public opinion surveys. Results from polling research that produced findings contrary to the industry's position were suppressed. In order to demonstrate smoker outrage against a ban, later efforts included the sponsorship of smokers' rights and other front groups. Congressional allies and industry consultants sought to discredit the science underlying proposals to ban smoking and individual tobacco companies conducted their own cabin air quality research. Faced with the potential of a ban on all domestic flights, the industry sought to intimidate an air carrier and a prominent policymaker. Despite the intensification of tactics over time, including mobilisation of an army of lobbyists and Congressional allies, the tobacco industry was ultimately defeated. Conclusions Our longitudinal analysis provides insights into how and when the industry changed its plans and provides public health advocates with potential counterstrategies. PMID:16885582

    We provide an overview of tobacco smoking patterns in Pacific island countries and territories to facilitate monitoring progress toward the goal of a Tobacco-Free Pacific by 2025. We examined data from 4 surveys conducted in the region between 2001 and 2013, including the STEPwise approach to surveillance for adults (2564 years); the Global School-Based Student Health Survey and the Global Youth Tobacco Survey (students 1315 years); and the Youth Risk Behavior Surveillance System (grade 912 students) in United States affiliated Pacific Islands (USAPIs). Adult smoking prevalence ranged from less than 5% of women in Vanuatu to almost 75% of men in Kiribati. Smoking prevalence among students (1315 years) ranged between 5.6% and 52.1%. There were declines in smoking among youths in many USAPIs. To achieve the tobacco-free goal and reduce disease burden, accelerated action is needed to align national legislation with international agreements and build capacity for tobacco control at all levels.

    Apoptosis is a vital mechanism for the regulation of cell turnover and plays a critical role in tissue homeostasis and development of many disease processes. Previous studies have demonstrated the apoptotic effect of tobacco smoke; however, the molecular mechanisms by which tobacco smoke triggers apoptosis remain unclear. In the present study we investigated the effects of tobacco smoke on the induction of apoptosis in the lungs of rats and modulation of nuclear factor-kappa B (NF-{kappa}B) in this process. Exposure of rats to 80 mg/m{sup 3} tobacco smoke significantly induced apoptosis in the lungs. Tobacco smoke resulted in inhibition of NF-{kappa}B activity, noted by suppression of inhibitor of {kappa}B (I{kappa}B) kinase (IKK), accumulation of I{kappa}B{alpha}, decrease of NF-{kappa}B DNA binding activity, and downregulation of NF-{kappa}B-dependent anti-apoptotic proteins, including Bcl-2, Bcl-xl, and inhibitors of apoptosis. Initiator caspases for the death receptor pathway (caspase 8) and the mitochondrial pathway (caspase 9) as well as effector caspase 3 were activated following tobacco smoke exposure. Tobacco smoke exposure did not alter the levels of p53 and Bax proteins. These findings suggest the role of NF-{kappa}B pathway in tobacco smoke-induced apoptosis.

    Introduction Tobacco smoking is highly prevalent among the HIV-1-infected population. In addition to diminished immune response, smoking has been shown to increase HIV-1 replication and decrease response to antiretroviral therapy, perhaps through drugdrug interaction. However, the mechanism by which tobacco/nicotine increases HIV-1 replication and mediates drugdrug interaction is poorly understood. Areas covered In this review, the authors discuss the effects of smoking on HIV-1 pathogenesis. Since they propose a role for the cytochrome P450 (CYP) pathway in smoking-mediated HIV-1 pathogenesis, the authors briefly converse the role of CYP enzymes in tobacco-mediated oxidative stress and toxicity. Finally, the authors focus on the role of CYP enzymes, especially CYP2A6, in tobacco/nicotine metabolism and oxidative stress in HIV-1 model systems monocytes/macrophages, lymphocytes, astrocytes and neurons, which may be responsible for HIV-1 pathogenesis. Expert opinion Recent findings suggest that CYP-mediated oxidative stress is a novel pathway that may be involved in smoking-mediated HIV-1 pathogenesis, including HIV-1 replication and drugdrug interaction. Thus, CYP and CYP-associated oxidative stress pathways may be potential targets to develop novel pharmaceuticals for HIV-1-infected smokers. Since HIV-1/TB co-infections are common, future study involving interactions between antiretroviral and antituberculosis drugs that involve CYP pathways would also help treat HIV-1/TB co-infected smokers effectively.

    Understanding the effects of tobacco smoking on neuroadaptations in GABAA receptor levels over alcohol withdrawal will provide critical insights for the treatment of comorbid alcohol and nicotine dependence. We conducted parallel studies in human subjects and nonhuman primates to investigate the differential effects of tobacco smoking and nicotine on changes in GABAA receptor availability during acute and prolonged alcohol withdrawal. We report that alcohol withdrawal with or without concurrent tobacco smoking/nicotine consumption resulted in significant and robust elevations in GABAA receptor levels over the first week of withdrawal. Over prolonged withdrawal, GABAA receptors returned to control levels in alcohol-dependent nonsmokers, but alcohol-dependent smokers had significant and sustained elevations in GABAA receptors that were associated with craving for alcohol and cigarettes. In nonhuman primates, GABAA receptor levels normalized by 1 mo of abstinence in both groups—that is, those that consumed alcohol alone or the combination of alcohol and nicotine. These data suggest that constituents in tobacco smoke other than nicotine block the recovery of GABAA receptor systems during sustained alcohol abstinence, contributing to alcohol relapse and the perpetuation of smoking.

    Background. Policymakers need estimates of the impact of tobacco control (TC) policies to set priorities and targets for reducing tobacco use. We systematically reviewed the independent effects of TC policies on smoking behavior. Methods. We searched MEDLINE (through January 2012) and EMBASE and other databases through February 2009, looking for studies published after 1989 in any language that assessed the effects of each TC intervention on smoking prevalence, initiation, cessation, or price participation elasticity. Paired reviewers extracted data from studies that isolated the impact of a single TC intervention. Findings. We included 84 studies. The strength of evidence quantifying the independent effect on smoking prevalence was high for increasing tobacco prices and moderate for smoking bans in public places and antitobacco mass media campaigns. Limited direct evidence was available to quantify the effects of health warning labels and bans on advertising and sponsorship. Studies were too heterogeneous to pool effect estimates. Interpretations. We found evidence of an independent effect for several TC policies on smoking prevalence. However, we could not derive precise estimates of the effects across different settings because of variability in the characteristics of the intervention, level of policy enforcement, and underlying tobacco control environment.

    The issue of environmental tobacco smoke (ETS) and the harms it causes to nonsmoking bystanders has occupied a central place in the rhetoric and strategy of antismoking forces in the United States over the past 3 decades. Beginning in the 1970s, anti-tobacco activists drew on suggestive and incomplete evidence to push for far-reaching prohibitions on smoking in a variety of public settings. Public health professionals and other antismoking activists, although concerned about the potential illness and death that ETS might cause in nonsmokers, also used restrictions on public smoking as a way to erode the social acceptability of cigarettes and thereby reduce smoking prevalence. This strategy was necessitated by the context of American political culture, especially the hostility toward public health interventions that are overtly paternalistic. PMID:12036788

    A minireview is presented concerning the use of cotinine as a tobacco-smoke exposure index. First, general considerations about methods for the determination of urinary cotinine are presented. Besides pure analytical aspects, this minireview considers major problems encountered in the establishment of threshold values that can be used to distinguish not only smokers from nonsmokers but also nonsmokers exposed or not exposed to environmental tobacco smoke (ETS). In addition, the use of urinary cotinine is illustrated in several situations where smoking status assessment is of interest. Such situations include evaluation of the impact of smoking cessation programs, monitoring of pregnancy and of other groups at risk, assessment of occupational exposure to industrial pollutants, validation of phase I clinical trials, and the control of life insurance candidates. The specific problem of ETS exposure assessment is briefly mentioned. PMID:9591157

    Background The tobacco industry has long sought affiliation with major sporting events, including the Olympic Games, for marketing, advertising and promotion purposes. Since 1988, each Olympic Games has adopted a tobacco-free policy. Limited study of the effectiveness of the smoke-free policy has been undertaken to date, with none examining the tobacco industry’s involvement with the Olympics or use of the Olympic brand. Methods and Findings A comparison of the contents of Olympic tobacco-free policies from 1988 to 2014 was carried out by searching the websites of the IOC and host NOCs. The specific tobacco control measures adopted for each Games were compiled and compared with measures recommended by the WHO Tobacco Free Sports Initiative and Article 13 of the Framework Convention on Tobacco Control (FCTC). This was supported by semi-structured interviews of key informants involved with the adoption of tobacco-free policies for selected games. To understand the industry’s interests in the Olympics, the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) was systematically searched between June 2013 and August 2014. Company websites, secondary sources and media reports were also searched to triangulate the above data sources. This paper finds that, while most direct associations between tobacco and the Olympics have been prohibited since 1988, a variety of indirect associations undermine the Olympic tobacco-free policy. This is due to variation in the scope of tobacco-free policies, limited jurisdiction and continued efforts by the industry to be associated with Olympic ideals. Conclusions The paper concludes that, compatible with the IOC’s commitment to promoting healthy lifestyles, a comprehensive tobacco-free policy with standardized and binding measures should be adopted by the International Olympic Committee and all national Olympic committees.

    Background: Childhood exposure to environmental tobacco smoke has been extensively associated with childhood respiratory illness; fewer studies have addressed the effects on adults. Methods: Childhood environmental tobacco smoke exposure in relation to chronic cough, phlegm, and asthma diagnosis was studied in never smokers from a cohort of Singaporeans of Chinese ethnicity aged 4574 years at enrolment from 1993 to 1998. From 1999 to 2004 subjects were interviewed regarding environmental tobacco smoke exposure before and after the age of 18 and the presence and duration of current symptoms of chronic cough and phlegm production and asthma diagnosis. Results: Among 35 000 never smokers, fewer had smoking mothers (19%) than fathers (48%). Although few subjects currently lived (20%) or worked (4%) with smokers, 65% reported living with a daily smoker before the age of 18 years. Living with a smoker before the age of 18 increased the odds of chronic dry cough (149 cases, odds ratio 2.1, 95% CI 1.4 to 3.3) and, to a lesser extent, phlegm, after adjustment for age, sex, dialect group, and current and past exposure to smokers at home and at work after the age of 18. Associations strengthened with higher numbers of smokers in childhood. There was no association with asthma or chronic bronchitis. There was evidence to suggest a stronger association among subjects with a lower adult intake of fibre which has previously been found to be protective for respiratory symptoms. Conclusions: In this large study of non-smokers, living with a smoker in childhood was associated with chronic dry cough and phlegm in adulthood, independent of later exposures to environmental tobacco smoke.

    Tobacco smoke is the leading cause of preventable premature death worldwide. While the majority of smokers would like to stop, the habitual and addictive nature of smoking makes cessation difficult. Clinical guidelines suggest that smoking cessation interventions should include both behavioural support and pharmacotherapy (e.g. nicotine replacement therapy). This commentary paper focuses on the important role of behavioural interventions in encouraging and supporting smoking cessation attempts. Recent developments in the field are discussed, including 'cut-down to quit', the behaviour change techniques taxonomy (BCTT) and very brief advice (VBA) on smoking. The paper concludes with a discussion of the important role that health professionals can and should play in the delivery of smoking cessation interventions. PMID:25114563

    Tobacco smoking is associated with numerous pathological conditions. Compelling experimental evidence associates smoking to the degeneration of the intervertebral disc (IVD). In particular, it has been shown that nicotine down-regulates both the proliferation rate and glycosaminoglycan (GAG) biosynthesis of disc cells. Moreover, tobacco smoking causes the constriction of the vascular network surrounding the IVD, thus reducing the exchange of nutrients and anabolic agents from the blood vessels to the disc. It has been hypothesized that both nicotine presence in the IVD and the reduced solute exchange are responsible for the degeneration of the disc due to tobacco smoking, but their effects on tissue homeostasis have never been quantified. In this study, a previously presented computational model describing the homeostasis of the IVD was deployed to investigate the effects of impaired solute supply and nicotine-mediated down-regulation of cell proliferation and biosynthetic activity on the health of the disc. We found that the nicotine-mediated down-regulation of cell anabolism mostly affected the GAG concentration at the cartilage endplate, reducing it up to 65% of the value attained in normal physiological conditions. In contrast, the reduction of solutes exchange between blood vessels and disc tissue mostly affected the nucleus pulposus, whose cell density and GAG levels were reduced up to 50% of their normal physiological levels. The effectiveness of quitting smoking on the regeneration of a degenerated IVD was also investigated, and showed to have limited benefit on the health of the disc. A cell-based therapy in conjunction with smoke cessation provided significant improvements in disc health, suggesting that, besides quitting smoking, additional treatments should be implemented in the attempt to recover the health of an IVD degenerated by tobacco smoking.

    It is an accepted truth that tobacco, as well as second-hand smoke, causes lung and other cancers. This health policy fact sheet examines the need and implications for tobacco control legislation in the United States. Major stakeholders and special interest groups influence whether or not further tobacco control legislation can be passed and who it affects. This paper will review not only the ethical implications, such as the ethical theory, ethical principles and ethical rules of conduct that support tobacco control legislation, but also its legal and economic implications as well as media influences. This paper concludes with the authors' assessment that the United States is in fact in need of more tobacco control legislation. PMID:21939486

    This study was designed to demonstrate that dopaminergic stimulation would result in decreased smoking behavior and nicotine intake, whereas dopaminergic blockade would result in increased smoking behavior and nicotine intake, in the same subjects. In prior human studies, a dopaminergic antagonist, haloperidol, increased smoking and/or nicotine intake, and a dopamine agonist, bromocriptine, decreased smoking. The smoking behavior of 20 heavy smokers was observed on two separate visits in a randomized, double-blind, repeated-measures-within-subject design. In the drug-reversal design, either bromocriptine (2.5 mg) or haloperidol (2.0 mg) was administered at each 5-h session, during which subjects smoked their own cigarettes ad libitum. Smoking topography was measured using a thermistor flow detector apparatus. Subjects smoked their cigarettes faster (p<0.05) and total puffing time was greater (p<0.05) with haloperidol than with bromocriptine. There was a trend for both a shorter latency to smoke (p<0.10, one-tailed) during time of expected peak drug concentration and for a shorter inter-cigarette interval with haloperidol than with bromocriptine (p<0.10, one-tailed). Shiffman-Jarvik Withdrawal Scale craving subscale scores increased significantly more with haloperidol than with bromocriptine (p<0.05). Mean Profile of Mood States (POMS) scores differed significantly for only one subscale (Confusion: bromocriptine>haloperidol; p<0.05). These data support the hypothesis that nicotine mediates reinforcement from smoking via dopamine, and that smoking behavior can be manipulated within the same subjects in opposite directions by alternately stimulating and blocking dopamine.

    Background Health concerns around cannabis use have focused on the potential relationship with psychosis but the effect of cannabis smoking on respiratory health has received less attention. Aim To investigate the association between tobacco-only smoking compared with tobacco plus cannabis smoking and adverse outcomes in respiratory health and lung function. Design and setting The design was cross-sectional with two groups recruited: cigarette smokers with tobacco pack-years; cannabis smokers with cannabis joint-years. Recruitment occurred in a general practice in Scotland with 12 500 patients. Method Exposures measured were tobacco smoking (pack-years) and cannabis smoking (joint-years). Cannabis type (resin, herbal, or both) was recorded by self-report. Respiratory symptoms were recorded using NHANES and MRC questionnaires. Lung function was measured by spirometry (FEV1/FVC ratio). Results Participants consisted of 500 individuals (242 males). Mean age of tobacco-only smokers was 45 years; median tobacco exposure was 25 pack-years. Mean age of cannabis and tobacco smokers was 37 years; median tobacco exposure was 19 pack-years, rising to 22.5 when tobacco smoked with cannabis. Although tobacco and cannabis use were associated with increased reporting of respiratory symptoms, this was higher among those who also smoked cannabis. Both tobacco and cannabis users had evidence of impaired lung function but, in fully adjusted analyses, each additional joint-year of cannabis use was associated with a 0.3% (95% confidence interval = 0.0 to 0.5) increase in prevalence of chronic obstructive pulmonary disease. Conclusion In adults who predominantly smoked resin cannabis mixed with tobacco, additional adverse effects were observed on respiratory health relating to cannabis use. PMID:25624312

    The aim of the study was to examine the effects of tobacco smoking in pregnancy on children's IQ at the age of 5. A prospective follow-up study was conducted on 1,782 women, and their offspring were sampled from the Danish National Birth Cohort. At 5 years of age, the children were tested with the Wechsler Preschool and Primary Scale of Intelligence-Revised. Parental education, maternal IQ, maternal alcohol consumption in pregnancy, the sex and age of the child, and tester were considered core confounders, but the full model also controlled for prenatal paternal smoking, maternal age and Bodymass Mass Index, parity, family/home environment, postnatal parental smoking, breast feeding, the child's health status, and indicators for hearing and vision impairments. Unadjusted analyses showed a statistically significant decrement of 4 points on full-scale IQ (FSIQ) associated with smoking 10+ cigarettes per day compared to nonsmoking. After adjustment for potential confounders, no significant effects of prenatal exposure to tobacco smoking were found. Considering the indisputable teratogenic effects of tobacco smoking, these findings should be interpreted with caution. Still, the results may indicate that previous studies that failed to control for important confounders, particularly maternal intelligence, may be subject to substantial residual confounding.

    Introduction In 2004, Peru ratified the Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) and in 2006 passed Law 28705 for tobacco consumption and exposure reduction. The Global Youth Tobacco Survey (GYTS) provides data on youth tobacco use for development of tobacco control programs. Findings from the GYTS conducted in four main cities in Peru in 2000 and 2003 are reported in this paper and can be used to monitor provisions of the WHO FCTC. Methods The GYTS is a school-based survey that uses a standardized methodology for sampling, questionnaire construction, field procedures, and data management. In total, 5,332 and 7,824 students aged 13 to 15 years participated in the 2000 and 2003 surveys conducted in Huancayo, Lima, Tarapoto and Trujillo. Results In both years, Lima had the highest lifetime (54.6% and 59.6%) and current use of tobacco (18.6% and 19.2%) of the four cities. According to gender, boys smoked more than girls and less than 20% of students initiated smoking before the age of 10. Among smokers, more than 60% bought their cigarettes in a store with no restriction for their age, and approximately 12% had ever been offered "free cigarettes". Around 90% of students were in favor of banning smoking in public places. Changes between 2000 and 2003 included an increase in the percentage of smokers who wanted to have a cigarette first thing in the morning in Tarapoto (from 0% to 1.2%) and a decrease in exposure to tobacco at home in Huancayo (from 23.7% to 17.8%) and Trujillo (from 27.8% to 19.8%) Conclusion While few changes in tobacco use among youth have been observed in the GYTS in Peru, the data in this report can be used as baseline measures for future evaluation efforts. At this time, tobacco control efforts in Peru need to focus on enhancing Law 28705 to include enforcement of existing provisions and inclusion of new laws and regulations. Most of these provisions are required of all countries, such as Peru, that have ratified the WHO FCTC. PMID:19091045

    Background Tobacco use became an ingrained habit in the United States (US) following the First World War and a large proportion of physicians, similar to the general population, were smokers. The period from 1949 to 1984 was a pivotal era of change however, as the medical profession, like the society it served, became increasingly aware of the dangers that tobacco incurred for health. Methods An extensive review targeted all manuscripts published in academic journals between 1949 and 1984 that related to tobacco smoking among US physicians. The study was undertaken in 2007–08 with an internet search of relevant medical databases, after which time the reference lists of manuscripts were also examined to find additional articles. Results A total of 57 manuscripts met the inclusion criteria. From a research perspective, the methodology and coverage of smoking surveys ranged from detailed national investigations, to local medical association surveys, and journal readership questionnaires. From a historical perspective, it can be seen that by the 1950s many US physicians had begun questioning the safety of tobacco products, and by the 1960s and 1970s, this had resulted in a continuous decline in tobacco use. By the 1980s, few US physicians were still smoking, and many of their younger demographic had probably never smoked at all. Conclusion Although the quality and coverage of historical surveys varied over time, a review of their main results indicates a clear and consistent decline in tobacco use among US physicians between 1949 and 1984. Much can be learned from this pivotal era of public health, where the importance of scientific knowledge, professional leadership and social responsibility helped set positive examples in the fight against tobacco.

    Environmental factors such as tobacco smoking may have long-lasting effects on DNA methylation patterns, which might lead to changes in gene expression and in a broader context to the development or progression of various diseases. We conducted an epigenome-wide association study (EWAs) comparing current, former and never smokers from 1793 participants of the population-based KORA F4 panel, with replication in 479 participants from the KORA F3 panel, carried out by the 450K BeadChip with genomic DNA obtained from whole blood. We observed wide-spread differences in the degree of site-specific methylation (with p-values ranging from 9.31E-08 to 2.54E-182) as a function of tobacco smoking in each of the 22 autosomes, with the percent of variance explained by smoking ranging from 1.31 to 41.02. Depending on cessation time and pack-years, methylation levels in former smokers were found to be close to the ones seen in never smokers. In addition, methylation-specific protein binding patterns were observed for cg05575921 within AHRR, which had the highest level of detectable changes in DNA methylation associated with tobacco smoking (24.40% methylation; p?=?2.54E-182), suggesting a regulatory role for gene expression. The results of our study confirm the broad effect of tobacco smoking on the human organism, but also show that quitting tobacco smoking presumably allows regaining the DNA methylation state of never smokers.

    Background Using smokeless tobacco and smoking are risk behaviors for oral cancer, soft tissue lesions, caries, periodontal disease and other oral conditions. The purpose of this study was to examine adolescent smokeless tobacco use and smoking. Methods The study was a cross-sectional analysis of participants with complete data on smoking, smokeless tobacco use, and other variables of interest in the 2011 Youth Risk Behavior Survey (n=9655). Descriptive analysis and multivariable logistic regression analyses were performed. Results The unadjusted odds ratio for smokeless tobacco use and smoking was 9.68 (95% CI: 7.72, 12.13, p<.0001); the adjusted odds ratio was 3.92 (95%CI: 2.89, 5.31, p<.0001). Adolescents using smokeless tobacco were more likely to be male, to smoke, and to have engaged in binge drinking. Conclusions Adolescents who are using smokeless tobacco are more likely to also be engaging in concomitant smoking and are participating in other risk-taking behaviors. Practice implications Dentists are involved in helping patients in tobacco cessation. The strong association of smoking with smokeless tobacco needs to be considered in designing cessation programs for adolescents. PMID:23904581

    Environmental Tobacco Smoke (ETS) is ranked as one of the factors of confirmed carcinogenicity to human. It consists of the mixture of smoke exhaled by the smoker as well as the sidestream smoke and contains many times higher concentrations of some toxic substances in comparison to the amount of toxic compounds inhaled by a smoker. From many years the issue of passive smoking has been the subject of many research and still not all of its aspects of affecting human health have been explored. Apart from the tobacco varieties, also diverse additives added during the process of tobacco manufacturing, including particularly carbohydrates, influence the composition of the environmental tobacco smoke. During smoking they can undergo many complex transformations, as a result of which toxic components of the environmental tobacco smoke are formed, carbonyl compounds in particular, like aldehydes. They are marked by a significant chemical reactivity which enables them to modify amino groups of proteins leading to the changes in their structure, biological functions and often antigenicity. Therefore their influence to the human body is the cause of numerous adverse health effects caused by the increase in free radical processes which can constitute to the source of these compounds. Well known representative of this group of xenobiotics is formaldehyde as a compound that reflects well the environmental exposure to carbonyl compounds. The considerable source of this compound is tobacco smoke. Therefore analysis of formaldehyde in body fluids is a valuable biomonitoring tool of exposure to it. The aim of this study was the evaluation of formaldehyde concentration in urine samples of medicine students exposed to ETS. The study material consisted of 149 urine samples of students from School of Medicine with the Division of Dentistry in Zabrze, Medical University of Silesia. The concentration of formaldehyde in urine samples was determined by a spectrophotometric method using the Purpald reagent. To verify the collected questionnaire data regarding exposure to constituents of tobacco smoke, the immuno-enzymatic method was used to determine main nicotine metabolites in tested urine samples. This enabled dividing the investigated students' group into active smokers, passively exposed to tobacco smoke and not exposed. Analysis of obtained results showed that mean concentration of formaldehyde in urine of active smokers (68.45 ± 58.67 µmol/l) and passive smokers (79.23 ± 53.64 µmol/l) were significantly higher in comparison to not exposed students (42.99 ± 30.29 µmol/l). Mean concentrations of formaldehyde in urine samples of active and passive smokers are comparable. The results of our study allow to conclude that passive exposure to tobacco smoke is an equivalent source of exposure to active smoking regarding formaldehyde adverse influence to human. Applied method enables to quick evaluation of formaldehyde concentration in biological samples. PMID:26731871

    2009-01-01

    Four arguments have been used to support smokeless tobacco (ST) for harm reduction: (1) Switching from cigarettes to ST would reduce health risks; (2) ST is effective for smoking cessation; (3) ST is an effective nicotine maintenance product; and (4) ST is not a gateway for cigarette smoking. There is little evidence to support the first three arguments and most evidence suggests that ST is a gateway for cigarette smoking. There are ethical challenges to promoting ST use. Based on the precautionary principle, the burden of proof is on proponents to provide evidence to support their position; such evidence is lacking. PMID:19440266

    The tobacco-derived environmental emission of most common concern is the smoke issuing from cigarettes between puffs. A literature review of smoke formation mechanisms, sampling methods and selected emission factors suggests that sidestream deliveries are actually much less variable than is commonly thought. Examples of devices used to generate and collect sidestream smoke for analysis are described and their advantages and disadvantages discussed. Emissions computed as is common practice from sidestream/mainstream ratios are compared to those determined directly. The ratio method can yield misleading results because of the sensitivity of mainstream deliveries to cigarette and burn characteristics.

  5. Socioeconomic Status and the Reward Value of Smoking Following Tobacco Abstinence: A Laboratory Study

    Leventhal, Adam M.

    2014-01-01

    Introduction: Socioeconomic status (SES) indicators are robustly associated with smoking behaviors. Yet, the psychological mechanisms underlying relations are unclear. This study merged the socioecological construct of SES with laboratory psychological science to investigate how income, education, and employment status predicted the reward value of smoking following tobacco abstinence among a diverse sample of adult daily smokers. We hypothesized that participants with lower SES (i.e., less education, lower income, and unemployed) would experience greater abstinence-induced enhancement of the reward value of smoking. Methods: Adult smokers (N = 240; 68.7% male; 51.7% Black, 33.8% White, 7.1% Latino, and 7.5% other) attended 2 laboratory sessions (1 nonabstinent and 1 following 16-hr tobacco abstinence) involving behavioral assessment of (a) latency to smoking when delaying smoking was monetarily rewarded and (b) purchasing individual cigarettes. Generalized estimating equations were used to test the interaction between each SES variable (education, income, and employment) and abstinence state to illustrate whether participants with certain SES characteristics were more sensitive to the abstinence-induced enhancement of the relative reward value of smoking. Results: Participants who never attended college (vs. college attendees) exhibited greater abstinence-induced enhancement of the reward value of smoking, which was indicated by reduced willingness to delay smoking for money (ps = .03). Income and employment status did not moderate abstinence effects. Conclusions: Less-educated smokers were particularly motivated to smoke during acute abstinence. Observed educational disparities in smoking behaviors and smoking cessation might reflect a biased valuation of immediate drug-related (over less immediate alternative) rewards. Future research should explore potential mediators of this association. PMID:24935756

    This study was designed to estimate the relationship between exposure to tobacco retail outlets and smoking initiation in a racially diverse urban setting. Using data from the 2011 NYC Youth Risk Behavior Survey, multivariable logistic regression analyses were conducted to estimate the exposure-initiation relationship and test for effect modification, while controlling for covariates. The predicted probability of smoking initiation from the multivariable model increased from 7.7% for zero times a week exposed to tobacco retailers to 16.0% for exposure seven times or more per week. The odds of initiation were significantly higher among adolescents exposed to tobacco retail outlets two times or more a week compared with those exposed less often (AOR?=?1.41; 95% CI: 1.08, 1.84). Risk-taking behavior modified the relationship between exposure and initiation, with the odds of initiation highest among those low in risk-taking (AOR?=?1.78; 95% CI: 1.14, 1.56). These results are consistent with past research, showing that frequent exposure to tobacco marketing in retail settings is associated with increased odds of initiation. Reducing exposure to tobacco retail marketing could play an important role in curtailing smoking among adolescents, especially those less prone to risk-taking. PMID:23700202

    Objective To determine the mortality attributable to smoking and years of potential life lost from smoking among people in prison and whether bans on smoking in prison are associated with reductions in smoking related deaths. Design Analysis of cross sectional survey data with the smoking attributable mortality, morbidity, and economic costs system; population based time series analysis. Setting All state prisons in the United States. Main outcome measures Prevalence of smoking from cross sectional survey of inmates in state correctional facilities. Data on state prison tobacco policies from web based searches of state policies and legislation. Deaths and causes of death in US state prisons from the deaths in custody reporting program of the Bureau of Justice Statistics for 2001-11. Smoking attributable mortality and years of potential life lost was assessed from the smoking attributable mortality, morbidity, and economic costs system of the Centers for Disease Control and Prevention. Multivariate Poisson models quantified the association between bans and smoking related cancer, cardiovascular and pulmonary deaths. Results The most common causes of deaths related to smoking among people in prison were lung cancer, ischemic heart disease, other heart disease, cerebrovascular disease, and chronic airways obstruction. The age adjusted smoking attributable mortality and years of potential life lost rates were 360 and 5149 per 100 000, respectively; these figures are higher than rates in the general US population (248 and 3501, respectively). The number of states with any smoking ban increased from 25 in 2001 to 48 by 2011. In prisons the mortality rate from smoking related causes was lower during years with a ban than during years without a ban (110.4/100 000 v 128.9/100 000). Prisons that implemented smoking bans had a 9% reduction (adjusted incidence rate ratio 0.91, 95% confidence interval 0.88 to 0.95) in smoking related deaths. Bans in place for longer than nine years were associated with reductions in cancer mortality (adjusted incidence rate ratio 0.81, 95% confidence interval 0.74 to 0.90). Conclusions Smoking contributes to substantial mortality in prison, and prison tobacco control policies are associated with reduced mortality. These findings suggest that smoking bans have health benefits for people in prison, despite the limits they impose on individual autonomy and the risks of relapse after release. PMID:25097186

    This study explored infant physiologic responses of exposure to environmental tobacco smoke (ETS) using a longitudinal passive observation study with a control group. Fifteen smoking and 15 non-smoking mothers were initially contacted in hospital maternity units, with home visits made when their infants were 2, 4, and 6 weeks old. Exposure to ETS was measured using infant urinary nicotine and cotinine levels. The physiologic effects of infant ETS exposure were measured by rectal temperature, pulse rate, respiratory rate, blood pressure, and oxygen saturation. The smoking mothers in this sample were poorer, had less education, and were less likely to be married than the mothers who did not smoke. At birth, the infants of smoking mothers had higher diastolic blood pressure than infants of non-smoking mothers (p < .008). Mothers who smoke cigarettes should be educated that maternal smoking behavior can affect an infant's cardiovascular function. Parents should also be counseled about the risks of smoking in close proximity and/or in an enclosed space with an infant, especially in a motor vehicle. PMID:22945973

  10. What is tobacco smoke? Sociocultural dimensions of the association with cardiovascular risk.

    The definition of smoking as the inhalation of the smoke of burned tobacco that may occur occasionally or habitually as a consequence of a physical addiction to some chemicals, primarily nicotine, cannot be fully accepted today since several clinical, biological, metabolic, epidemiologic, statistic and socio-economic factors which play a basic role in determining individual damage due to smoking are missing in this assessment. The analysis of findings shows undoubtedly that several constituents of cigarette smoking play a strong role in the development and progression of cardiovascular damage, primarily atherosclerotic lesions. Nicotine and its metabolites, carbon monoxide and thiocyanate seem to be the most specific markers of damage that, in the time, becomes irreversible. Cigarette smoking is addictive because of nicotine and nicotine withdrawal causes many side effects of quitting smoking as well as nicotine itself usually increases cardiovascular risk. Therefore, what is smoking? Smoking must be defined as a chemical toxicosis which is able to cause detrimental effects either of acute or chronic type on different structures of the body being some of these like cardiovascular system, respiratory system and epithelial glands target organs. Smoking also causes physical addiction, primarily due to nicotine, that adversely influences smoking cessation. From these observations there is evidence that a large number of socio-economic and epidemiologic implications arise in smokers and that requires the necessity of specific structures which may help to face up the problem.

    Abnormal interhemispheric functional connectivity correlates with several neurologic and psychiatric conditions, including depression, obsessive-compulsive disorder, schizophrenia, and stroke. Abnormal interhemispheric functional connectivity also correlates with abuse of cannabis and cocaine. In the current report, we evaluated whether tobacco abuse (i.e., cigarette smoking) is associated with altered interhemispheric connectivity. To that end, we examined resting state functional connectivity (RSFC) using magnetic resonance imaging (MRI) in short term tobacco deprived and smoking as usual tobacco smokers, and in non-smoker controls. Additionally, we compared diffusion tensor imaging (DTI) in the same subjects to study differences in white matter. The data reveal a significant increase in interhemispheric functional connectivity in sated tobacco smokers when compared to controls. This difference was larger in frontal regions, and was positively correlated with the average number of cigarettes smoked per day. In addition, we found a negative correlation between the number of DTI streamlines in the genual corpus callosum and the number of cigarettes smoked per day. Taken together, our results implicate changes in interhemispheric functional and anatomical connectivity in current cigarette smokers. PMID:25805986

    The residual tobacco smoke contamination (thirdhand smoke, THS) on the clothes of a smoker was examined by direct analysis in real time (DART) mass spectrometry. DART-MS enabled sensitive and selective analysis of nicotine as the indicator of tobacco smoke pollution. Tandem mass spectrometric (MS/MS) experiments were also performed to confirm the identification of nicotine. Transferred thirdhand smoke originated from the fingers of a smoker onto other objects was also detected by DART mass spectrometry. DART-MS/MS was utilized for monitoring the secondhand tobacco smoke (SHS) in the air of the laboratory using nicotine as an indicator. To the best of our knowledge, this is the first report on the application of DART-MS and DART-MS/MS to the detection of thirdhand smoke and to the monitoring of secondhand smoke.

  19. The behavioral ecology of secondhand smoke exposure: A pathway to complete tobacco control

    Hughes, Suzanne C.

    2009-01-01

    Introduction: This article outlines a theoretical framework for research concerning secondhand smoke exposure (SHSe) prevention as a means to curtail the tobacco industry. Methods: The Behavioral Ecological Model (BEM) assumes interlocking social contingencies of reinforcement (i.e., rewards or punishments) from the highest level of society (e.g., taxing cigarette sales) to physiological reactions to nicotine that influence smoking and SHSe. We review selected research concerning both policy and clinical efforts to restrict smoking and/or SHSe. Results: Research to date has focused on smoking cessation with modest to weak effects. The BEM and empirical evidence suggest that cultural contingencies of reinforcement should be emphasized to protect people from SHSe, especially vulnerable children, pregnant women, the ill, the elderly, and low-income adults who have not elected to smoke. Doing so will protect vulnerable populations from industry-produced SHSe and may yield more and longer-lasting cessation. Conclusions: Interventions that reduce SHSe may serve as a Trojan horse to counter the tobacco industry. Future studies should: (a) guide policies to restrict SHSe; (b) develop powerful community and clinical interventions to reduce SHSe; (c) test the degree to which policies and other contexts enhance the effects of clinical interventions (e.g., media programs disclosing the disingenuous marketing by the industry); and (d) investigate the effects of all health care providers ability to reduce SHSe and generate an antitobacco culture, by advising all clients to avoid starting to smoke, to protect their children from SHSe, and to quit smoking.

    This study examined a proposed mechanism by which exposure to cigarette advertising may mediate the subsequent smoking of youth. We hypothesized that children's exposure to cigarette advertising leads them to overestimate the prevalence of smoking, and that these distorted perceptions, in turn, lead to increased intentions to smoke. Children in Finland, where there has been a total tobacco advertising ban since 1978, were compared with children in the United States at a time when tobacco advertising was ubiquitous. Samples of 477 8- to 14-year-old Helsinki students and 453 8- to 14-year-old Los Angeles students whose lifetime cigarette use consisted of no more than a puff of a cigarette were administered questionnaires in their classrooms. The primary hypothesis was confirmed. Los Angeles youth were significantly more likely than Helsinki youth to overestimate the prevalence of adult smoking, in spite of the fact that actual adult smoking prevalence in Helsinki was almost twice that of Los Angeles adults. A similar, significant pattern for perceived peer smoking was obtained, with Los Angeles youth being more likely than Helsinki youth to overestimate prevalence, in spite of the actual greater prevalence of youth smoking in Helsinki.

    A comparative analysis of smoking habits, based on data from three different sources, shows that the present level of tobacco consumption in Norway is at a mid-Nordic level, but lower in a European perspective. There has been a 25% decline in per capita consumption of tobacco since the mid-1970s, and the decrease has been most pronounced during the 1990s. The current rate of decline is the same as in the other Nordic countries. The prevalence of smoking among men is at present lower in Norway than in most European countries outside the Nordic ones. Since the mid-1950s, the prevalence of daily smoking among Norwegian men has decreased from approximately 70% to 35% in 1997. However, within the last ten years the decline has levelled out and smoking among men has been stable in recent years. Smoking among women is more widespread in Norway than in most European countries. The number of female smokers reached a peak around 1970. Since the 1970s, the prevalence of smoking among women has been stable. The prevalence of daily smoking in the age-group 16-24 years is currently at a mid-European level. However, the decline observed during the late 1970s and the first half of the 1980s does seem to have levelled out during the 1990s. PMID:9656814

    Nicotine is a potential marker for environmental tobacco smoke (ETS) because it is unique to tobacco smoke and is a major constituent of the smoke. An air sampling method is presented which efficiently collects both particulate and vapor phase nicotine. Two filters are assembled in tandem in a personal sampling cassette. The first filter collects total or size fractional particules and the second is treated with sodium bisulfate to collect vapor phase nicotine and nicotine which has volatilized from the paniculate material collected on the first filler. The nicotine is then desorbed from the filters and analyzed by gas chromatography with nitrogen sensitive detection. The sampling method was evaluated in an environmental chamber under controlled conditions of temperature, humidity, ventilation and smoking rate. It was then employed in a field study of particulate exposures of railroad office workers and railroad mechanics to determine the portion of the particulate exposure attributable to environmental tobacco smoke. The method was found to be efficient and sensitive for the determination of nicotine levels in air.

    To document passive smoke exposure, the authors measured concentrations of serum cotinine, a major metabolite of nicotine, in 38 young children and compared the results with the smoking histories of home residents. Cotinine was detected in 26 children (68%), of which ten had no household exposure according to a questionnaire. The serum cotinine concentration was significantly elevated in blacks compared with whites after controlling for the number of smokers in the home. After stratifying by race, there was a significant direct correlation between the serum cotinine concentration and the number of smokers in the home, the amount smoked by the mother, and the amount smoked by others in the home. We conclude that the serum cotinine concentration is a useful indicator of the actual exposure of young children to tobacco smoke and that unexplained racial differences in cotinine levels exist.

  5. Pushing up smoking incidence: plans for a privatised tobacco industry in Moldova.

    PubMed

    Gilmore, Anna B; Radu-Loghin, Cornel; Zatushevski, Irina; McKee, Martin

    Moldova, one of the former Soviet republics and Europe's poorest country, has so far resisted pressure to privatise its tobacco industry. This paper examines the policies pursued by the transnational tobacco companies in Moldova in order to inform the ongoing debate about tobacco industry privatisation. We analysed relevant internal industry documents made public through litigation. The documents suggest that although a competitive tender for the state owned monopoly was later announced, British American Tobacco (BAT) and the German manufacturer Reemtsma each initially sought to secure a closed deal, with BAT accusing Reemtsma of underhand tactics. Imperial Tobacco, which now owns Reemstma, was unable to comment on these allegations as it only acquired Reemstma after the events in question. BAT sought to acquire a monopoly position, bolstered by excise rules developed by the company that would uniquely favour its products. Despite hoping to establish a monopoly, it planned intensive marketing, as if in a competitive market, aiming to target young urban dwellers, particularly opinion leaders. In so doing it predicted that smoking uptake would increase, especially among women. The documents also suggest that BAT was aware of the sensitive nature of its plans to cull the processing workforce and aimed to present "sanitised" information on future employment levels to the Moldovans. The potential for tobacco industry privatisation to undermine tobacco control and promote cigarette consumption is highlighted and is consistent with economic theory. Countries planning tobacco industry privatisation should ensure a transparent and competitive privatisation process, seek to prevent the predicted increase in consumption by implementing effective tobacco control policies and consider the impacts on employment. Multilateral financial organisations promoting tobacco industry privatisation could ensure their loan conditions protect public health by making the implementation of tobacco control policies a pre-requisite for privatisation.

    Despite the dangers of smoking, tobacco companies continue to impede tobacco control efforts through deceptive marketing practices. Media campaigns that expose these practices have been effective in advancing anti-industry attitudes and reducing smoking initiation among young people, yet the association between knowledge of industry practices and smoking cessation and relapse has not been studied. In a large military sample entering Air Force Basic Military Training (BMT), where tobacco use is prohibited, we investigated (i) the prevalence of agreement with a statement that tobacco companies have misled the public about the health consequences of smoking and (ii) the association of this acknowledgement with smoking status upon entry into BMT (N?=?36 013). At baseline, 56.6% agreed that tobacco companies have been deceptive, and agreement was a strong predictor of smoking status [smokers less likely to agree, odds ratio (OR)?=?0.39, P < 0.01]. At 12-month follow-up, we examined the association between industry perception at baseline and current smoking status (N?=?20 672). Recruits who had been smoking upon entry into BMT and who had acknowledged industry deception were less likely to report current smoking (OR?=?0.84, P?=?0.01). These findings suggest that anti-industry attitudes may affect smoking relapse following cessation. PMID:19528314

    Abstract Objective To determine the impact of tobacco control policies and mass media campaigns on smoking prevalence in Australian adults. Methods Data for calculating the average monthly prevalence of smoking between January 2001 and June 2011 were obtained via structured interviews of randomly sampled adults aged 18 years or older from Australias five largest capital cities (monthly mean number of adults interviewed: 2375). The influence on smoking prevalence was estimated for increased tobacco taxes; strengthened smoke-free laws; increased monthly population exposure to televised tobacco control mass media campaigns and pharmaceutical company advertising for nicotine replacement therapy (NRT), using gross ratings points; monthly sales of NRT, bupropion and varenicline; and introduction of graphic health warnings on cigarette packs. Autoregressive integrated moving average (ARIMA) models were used to examine the influence of these interventions on smoking prevalence. Findings The mean smoking prevalence for the study period was 19.9% (standard deviation: 2.0%), with a drop from 23.6% (in January 2001) to 17.3% (in June 2011). The best-fitting model showed that stronger smoke-free laws, tobacco price increases and greater exposure to mass media campaigns independently explained 76% of the decrease in smoking prevalence from February 2002 to June 2011. Conclusion Increased tobacco taxation, more comprehensive smoke-free laws and increased investment in mass media campaigns played a substantial role in reducing smoking prevalence among Australian adults between 2001 and 2011.

    Previous data have shown that high dose of nicotine administration or tobacco smoke exposure can reduce cell formation and the survival rate of adult-born neurons in the dentate gyrus. Here, we subjected adult mice to low intensity cigarette smoke exposure over long time periods. We did a 2×30min/day smoke exposure with two cigarettes per occasion over 1- or 2-months. Subsequently, we carried out a systematic quantitative histopathological analysis to assess the number of newborn neurons in the dentate gyrus. To investigate cell proliferation, the exogenous marker 5-bromo-2'-deoxyuridine (BrdU) was administered on the last experimental day and animals were sacrificed 2h later. To investigate the effect of tobacco smoke on the population of immature neurons, we quantified the number of doublecortin-positive (DCX+) neurons in the same animals. We found that exposing animals to cigarette smoke for 1- or 2-months had no influence on cell proliferation rate, but significantly reduced the number of DCX-positive immature neurons. Our tobacco smoke exposure regimen caused no substantial changes in respiratory functions, but histopathological analysis of the pulmonary tissue revealed a marked perivascular/peribronchial edema formation after 1-month and signs of chronic pulmonary inflammation after 2-months of cigarette smoke exposure. These data demonstrate that even mild exposure to cigarette smoke, without significantly affecting respiratory functions, can have a negative effect on adult-born neurons in the dentate gyrus, when applied over longer time periods. Our data indicate that besides nicotine other factors, such as inflammatory mediators, may also contribute to this effect. PMID:26792108

    Background Childhood tobacco exposure has been linked with sinonasal pathology, and may be associated with allergic sensitization. This study evaluates the association between exposure to active smoking or secondhand smoke (SHS) and the prevalence of rhinitis and allergic sensitization in the U.S. pediatric population. Methods Cross-sectional study in 2714 children and adolescents aged 6 to 19 in the National Health and Nutrition Examination Survey (NHANES), 20052006. Active smoking was defined as self-reported smoking or serum cotinine concentrations >10 ng/mL. SHS was defined as nonactive smokers who reported living with ?1 smokers or had serum cotinine ?0.011 ng/mL. Self-reported rhinitis was based on symptoms during the past 12 months, and allergen sensitization was defined as a positive response to any of the 19 specific immunoglobulin E (IgE) antigens tested. Results About half of the population (54%) had detectable levels of IgE specific to at least 1 of the tested allergens, and 25% reported a history of rhinitis. After multivariate adjustment, an increased prevalence rate ratio (PRR) of self-reported rhinitis was seen in individuals in the highest cotinine tertile among active smokers (PRR, 1.73; 95% confidence interval [CI], 1.23 to 2.43), with a significant trend between increasing cotinine levels in individuals exposed to either secondhand smoke or active smoking (p = 0.05 for both analyses). Significantly less food allergen sensitization was observed in participants in the highest cotinine tertile of secondhand smoke (PRR, 0.61; 95% CI, 0.43 to 0.85). Conclusion Tobacco smoke exposure was associated with increased prevalence of rhinitis symptoms, but decreased prevalence of allergic sensitization. The results highlight the complex relationship between tobacco exposure and sinonasal pathology. PMID:25884913

    Background: There is broad consensus regarding the health impact of tobacco use and secondhand smoke exposure, yet considerable ambiguity exists about the nature and consequences of thirdhand smoke (THS). Objectives: We introduce definitions of THS and THS exposure and review recent findings about constituents, indoor sorption–desorption dynamics, and transformations of THS; distribution and persistence of THS in residential settings; implications for pathways of exposure; potential clinical significance and health effects; and behavioral and policy issues that affect and are affected by THS. Discussion: Physical and chemical transformations of tobacco smoke pollutants take place over time scales ranging from seconds to months and include the creation of secondary pollutants that in some cases are more toxic (e.g., tobacco-specific nitrosamines). THS persists in real-world residential settings in the air, dust, and surfaces and is associated with elevated levels of nicotine on hands and cotinine in urine of nonsmokers residing in homes previously occupied by smokers. Much still needs to be learned about the chemistry, exposure, toxicology, health risks, and policy implications of THS. Conclusion: The existing evidence on THS provides strong support for pursuing a programmatic research agenda to close gaps in our current understanding of the chemistry, exposure, toxicology, and health effects of THS, as well as its behavioral, economic, and sociocultural considerations and consequences. Such a research agenda is necessary to illuminate the role of THS in existing and future tobacco control efforts to decrease smoking initiation and smoking levels, to increase cessation attempts and sustained cessation, and to reduce the cumulative effects of tobacco use on morbidity and mortality.

    The purpose of this study was to evaluate the influence of tobacco smoke on the pharmacokinetics of citalopram (CIT) and desmethylcitalopram (DCIT) and its enantiomers on an animal model. High performance liquid chromatography (HPLC) with a diode array detector (DAD) was used for the identification and quantification of the studied compounds. The HPLC quantification of racemic mixtures of CIT was performed on a C18 column. The limits of detection (LOD) and quantification (LOQ) were: 7 and 10 ng/ml respectively. HPLC separation of citalopram enantiomers (S- and R-CIT) was performed on a Chirobiotic V column. The limits of detection (LOD) and quantification (LOQ) were: 6 and 15 ng/ml for R- and S-CIT respectively. The experiment was carried out on male Wistar rats. The rats were exposed to tobacco smoke for five days (6 hours per day). After the exposure, citalopram was administered in a dose of 10 mg/kg intragastrically. In the control group (non-exposed animals), citalopram was administered in the same way and at an equal dose. The blood of the animals was collected at nine time points. It was found that tobacco smoke exposure inhibits the biotransformation of citalopram. The half-life of the racemic mixture of citalopram after intragastric administration was increased by about 287%. Changes in the pharmacokinetic parameters of S-citalopram (active isomer) show a similar tendency to those of the racemic mixture. The pharmacokinetics of R-citalopram showed no statistically important differences after tobacco smoke exposure. Alterations in the pharmacological parameters of desmethylcitalopram presented an opposite trend to the parent drug. After exposure to tobacco smoke, the induction of metabolism of this compound was observed. PMID:22460466

    Background There are many different kinds of cigarettes and tobacco available in the market. Since nicotine content of various brands of cigarettes are very variable, therefore evaluation and comparison of nicotine content of different brands of cigarettes is important. The goal of the present study was to determine and compare nicotine content of various domestic and imported cigarettes available in the area. Methods Fourteen popular imported brands and nine popular domestic brands of cigarettes and three available brands of tobaccos were investigated for the amounts of nicotine content. Nicotine was extracted from each cigarette and tobacco samples and was analyzed by high performance liquid chromatography (HPLC) method. Findings The amount of nicotine in each cigarette was from 6.17 to 12.65 mg (1.23 0.15 percent of tobacco weight in each cigarette) in domestic cigarettes. It was between 7.17-28.86 mg (1.80 0.25 percent of tobacco weight in each cigarette) for imported cigarette, and between 30.08- 50.89 mg (3.82 1.11 percent) for the pipe nicotine. There was significant difference in nicotine amount between imported and domestic brands of cigarettes. There was also no significant difference in nicotine content between light and normal cigarettes in imported brands. Conclusion Nicotine content of all tested cigarettes, imported and domestic brands, were higher than the international standard. PMID:24494133

    A prior study in a US state hospital suggested that schizophrenia is more closely associated with tobacco smoking when compared with other severe mental illnesses. This second study, in a neighborhood hospital, tries to (1) replicate that schizophrenia is associated with smoking and heavy smoking, and (2) rule out that this relationship is explained by substance use. The methodology was very similar to the first study. The sample included 588 inpatients. Logistic regression was used to develop models of variables associated with smoking or heavy smoking. The frequency of current smoking for the total, schizophrenic and non-schizophrenic samples were respectively 71, 75, and 55%. The sequence of frequencies from the highest to lowest was the same as in the first study: male schizophrenic patients, male non-schizophrenic patients, female schizophrenic patients and female non-schizophrenic patients. This second study consistently replicated the relationship between schizophrenia and smoking (after correcting for other variables) including history of alcohol and drug abuse or dependence. Only one of two definitions of heavy smoking showed a significant association with schizophrenia. In summary, these two studies suggest that schizophrenia is strongly associated with smoking. Neither substance use, antipsychotics, nor institutionalism can explain this relationship. PMID:12084420

We assessed young adults’ level of support for adult ratings for movies depicting smoking and for restrictions on tobacco magazine advertising. Methods Young adults from the U.S. Midwest were surveyed between 2010–2011 (n=2622). We assessed their level of support for (a) adult-rating all movies depicting smoking, and (b) restrictions on tobacco magazine advertising. Multivariate regression models were used to investigate the characteristics associated with higher level of support for these policies. Results Overall, 34% of the participants favored adult ratings for movies with smoking images, and 68% favored restrictions on tobacco magazine advertising. Characteristics associated with higher level of support differed somewhat by policy. Conclusion Further educating young adults about the influence of smoking images in movies on adolescent smoking may be necessary to gain more support for the policy. With the majority supporting restrictions on tobacco magazine advertising, it may be possible to tighten these restrictions to further protect adolescents. Future research is needed to identify how tobacco control advocates can frame these issues to gain further public support. PMID:25485169

    OBJECTIVES: This study assessed the implementation of tobacco industry strategies to prevent a workplace smoking regulation. METHODS: Tobacco industry internal documents were identified; hearing transcripts for the affiliations, arguments, and positions regarding the regulation of testifiers were coded; and media coverage was analyzed. RESULTS: Tobacco industry strategies sought to increase business participation and economic discussions at public hearings and to promote unfavorable media coverage of the regulation. The percentage of business representatives opposing the regulation grew from 18% (5 to 28) to 57% (13 of 23) between the hearings. Economic arguments opposing the regulation rose from 25% (7 of 28) to 70% (16 of 23). Press coverage was neutral and did not increase during the period of the regulatory hearings. CONCLUSIONS: The tobacco industry was successful in implementing 2 of its 3 strategies but was not able to prevent passage of the comprehensive workplace regulation. PMID:11111269

    The We Card program is the most ubiquitous tobacco industry youth smoking prevention program in the United States, and its retailer materials have been copied in other countries. The program's effectiveness has been questioned, but no previous studies have examined its development, goals, and uses from the tobacco industry's perspective. On the basis of our analysis of tobacco industry documents released under the 1998 Master Settlement Agreement, we concluded that the We Card program was undertaken for 2 primary purposes: to improve the tobacco industry's image and to reduce regulation and the enforcement of existing laws. Policymakers should be cautious about accepting industry self-regulation at face value, both because it redounds to the industry's benefit and because it is ineffective. PMID:20466965

    Background Longitudinal assessment of the impact of tobacco price on smoking cessation is scarce. Our objective was to investigate the effect of a price increase in October 2010 on cessation rates according to gender, age, socioeconomic status, and level of tobacco dependence in Japan. Methods We used longitudinal data linkage of two nationally representative studies and followed 2702 smokers for assessment of their cessation status. The odds ratios (ORs) for cessation were calculated using logistic regression. To estimate the impact of the 2010 tobacco price increase on cessation, data from 2007 were used as a reference category. Results Overall cessation rates significantly increased from 2007 to 2010, from 3.7% to 10.7% for men and from 9.9% to 16.3% for women. Cessation rates were 9.3% for men who smoked 1–10 cigarettes per day, 2.7% for men who smoked 11–20 cigarettes per day, and 2.0% for men who smoked more than 20 cigarettes per day in 2007. These rates increased to 15.5%, 10.0%, and 8.0%, respectively, in 2010. The impact was stronger among subjects who smoked more than 11 cigarettes per day than those who smoked 1–10 cigarettes per day in both sexes: ORs for 2010 were 4.04 for those smoking 11–20 cigarettes per day, 4.26 for those smoking more than 20 cigarettes per day, and 1.80 for those smoking 1–10 cigarettes per day in the main model in men. There were no obvious differences in the relationship between tobacco price increase and smoking cessation across age and household expenditure groups. Conclusions The tobacco price increase in Japan had a significant impact on smoking cessation in both sexes, especially among heavy smokers, with no clear difference in effect by socio-demographic status.

    Proper structure of the umbilical cord is important for the fetal development. We evaluated effects of toxic factors from tobacco smoke on fetal and umbilical cord morphometry. 109 women in weeks 29-40 of pregnancy (31 smokers with intrauterine growth restriction (IUGR); 28 non-smoking women with IUGR; 50 healthy pregnancies) were included. In smokers with IUGR, cotinine, cadmium and lead concentrations were significantly higher than in controls (mean 55.23ng/l; 1.52ng/ml; 14.85ng/ml vs 1.07; 0.34; 9.42) and inverse correlation between lead concentration and uncoiled umbilical cord was significant (r=-0.80). In smokers with IUGR, area of Wharton's jelly was increased compared to nonsmokers and controls. Inverse correlations occurred between cotinine and cadmium concentration and fetal percentile in smokers (r=-0.87; r=-0.87) and non-smokers (r=-0.47; r=-0.78) with IUGR. Exposure to tobacco smoke measured by cotinine, cadmium and lead concentration has an impact on fetal growth and umbilical cord morphometry and correlates with intensity of IUGR. PMID:26315940

    Background Heavier tobacco smoking among people with schizophrenia (SCZ) has been suggested to reflect self-medication of cognitive deficits. The idea that cognitive-enhancing effects of nicotine are a primary motivator of tobacco consumption in SCZ and that abstinence would deprive SCZ of such beneficial effects may explain hesitation among providers to pursue smoking cessation in SCZ. This study tested predictions of the cognitive self-medication hypothesis. Methods In three counterbalanced sessions, 17 SCZ and 17 healthy control subjects (HCS), all smokers, were tested under ad libitum smoking, or 3.5 hours after abstaining and receiving a nicotine (14 mg/24 hrs) or placebo patch. Results Attention task performance was improved by transdermal nicotine relative to placebo, with intermediate performance by ad libitum smoking. These effects were of similar size in SCZ and HCS, and did not reflect remediation of functions disproportionately impaired in SCZ. Although more SCZ reported that the need to concentrate influenced their smoking, this was not reflected by these patients' actual behavior. Self-reported ability to concentrate changed with nicotine status in HCS but not SCZ, suggesting insensitivity of SCZ to nicotine-derived performance benefits. Nicotine plasma concentrations after ad libitum smoking were not associated with performance benefits but instead with the propensity to experience nicotine withdrawal upon abstinence. This association was seen selectively in SCZ, suggesting a possible reason for heavier smoking. Conclusions These findings suggest that subjective or objective attentional benefits are unlikely the primary driving force of tobacco consumption in SCZ and should not discourage providers from supporting quit attempts.

    Purpose: Distant metastasis is the site of first relapse in approximately one-third of patients with locally advanced oropharyngeal carcinoma, irrespective of human papillomavirus status. Yet the risk factors associated with distant metastasis are not well characterized. We sought to characterize the relationship between smoking status and distant metastasis. Methods and Materials: We evaluated the association between tobacco smoking status and distant metastasis in a retrospective cohort study of 132 patients who underwent definitive radiation therapy and chemotherapy for Stage III-IVA/B oropharyngeal cancer. Information on tobacco smoking was prospectively collected by patient questionnaires and physician notes at the time of diagnosis. Thirty-three percent of the patients were nonsmokers, 51% were former smokers, 16% were active smokers. The cumulative lifetime tobacco smoking in pack-years was 20 (range, 0-150). Results: With a median follow-up time of 52 months, the overall rate of distant metastasis at 4 years was 8%. Distant metastasis was the most common first site of relapse, occurring in 56% of the patients with recurrences. Active smokers had higher rates of distant metastasis than non-active smokers (including never- and former smokers; 31% vs. 4%, p < 0.001) and former smokers (31% vs. 3%, p < 0.001). There was no statistically significant difference in the risk of distant metastasis for patients with lifetime cumulative pack-years >20 and {<=}20 (10% vs. 4%, p = 0.19). In univariate analysis, active smoking (p = 0.0004) and N category (p = 0.009) were predictive of increased risk of distant metastasis. In multivariate analysis, active smoking was the most significant predictive factor for increased risk of distant metastasis (hazard ratio, 12.7, p < 0.0001). Conclusions: This study identified a strong association between active smoking and distant metastasis in patients with oropharyngeal cancer.

    Background Diverse projects and guidelines to assist hospitals towards the attainment of comprehensive smoke-free policies have been developed. In 2006, Spain government passed a new smoking ban that reinforce tobacco control policies and banned completely smoking in hospitals. This study assesses the progression of tobacco control policies in the Catalan Network of Smoke-free Hospitals before and after a comprehensive national smoking ban. Methods We used the Self-Audit Questionnaire of the European Network for Smoke-free Hospitals to score the compliance of 9 policy standards (global score = 102). We used two cross-sectional surveys to evaluate tobacco control policies before (2005) and after the implementation of a national smoking ban (2007) in 32 hospitals of Catalonia, Spain. We compared the means of the overall score in 2005 and 2007 according to the type of hospital, the number of beds, the prevalence of tobacco consumption, and the number of years as a smoke-free hospital. Results The mean of the implementation score of tobacco control policies was 52.4 (95% CI: 45.4–59.5) in 2005 and 71.6 (95% CI: 67.0–76.2) in 2007 with an increase of 36.7% (p < 0.01). The hospitals with greater improvement were general hospitals (48% increase; p < 0.01), hospitals with > 300 beds (41.1% increase; p < 0.01), hospitals with employees' tobacco consumption prevalence 35–39% (72.2% increase; p < 0.05) and hospitals that had recently implemented smoke-free policies (74.2% increase; p < 0.01). Conclusion The national smoking ban appears to increase tobacco control activities in hospitals combined with other non-bylaw initiatives such as the Smoke-free Hospital Network. PMID:19473549

    In this study we evaluate the influence of tobacco smoke on the physico-chemical characteristics of PM 10 in different environments: outdoors, a smoking room, the same room after a 7-day absence of smokers and in a smoke-free office. The latter office was close to the smoking room, separated by a corridor. The coarse (PM 10-2.1) and fine (PM 2.1) fractions of PM 10 collected in the monitored areas were analysed by scanning electron microscopy, equipped with a thin-window system for X-ray microanalysis (SEM/EDX). Photo-electron spectroscopy (XPS) was used to study the elemental composition of the particulate and to identify the chemical state of atomic species detected. Four clusters of particles for both "fine" and "coarse" fractions were identified: carbonaceous particles, soil erosion particles, Ca-sulphates and metal compound particles. EDX spectra showed that a percentage of carbonaceous particles carried S, Si and metal traces. High-resolution XPS spectra of the C1s region showed a significant greater occurrence of the C-O/C-N functional group in the particulate fine fraction collected in the smoking room compared to that collected outdoors. The carbonaceous component of coarse fraction collected in the smoking room appeared dissimilar from the same component detected in the other areas. After the 7-day absence of smokers this component of the PM 10-2.1 fraction was similar to the corresponding coarse fraction collected at the outdoor location. The carbonaceous component of fine fraction collected in the smoking room, containing tobacco smoke products, such as organic carbon and nicotine, was traceable in the neighbouring areas, even several days after suspension of smoking activity.

    JAMA PEDIATRICS Associations Between Initial Water Pipe Tobacco Smoking and Snus Use and Subsequent Cigarette Smoking: Results From a Longitudinal Study of US Adolescents and Young Adults Samir Soneji, PhD; James D. Sargent, MD; Susanne E. Tanski, MD, MPH; Brian A. Primack, MD, PhD IMPORTANCE Many adolescents and young adults use alternative tobacco products, such as water pipes and snus, instead of cigarettes. OBJECTIVE To assess whether prior water pipe tobacco smoking and snus use among never smokers are risk factors for subsequent cigarette smoking. DESIGN, SETTING, AND PARTICIPANTS We conducted a 2-wave national longitudinal study in the United States among 2541 individuals aged 15 to 23 years old. At baseline (October 25, 2010, through June 11, 2011), we ascertained whether respondents had smoked cigarettes, smoked water pipe tobacco, or used snus. At the 2-year follow-up (October 27, 2012, through March 31, 2013), we determined whether baseline noncigarette smokers had subsequently tried cigarette smoking, were current (past 30 days) cigarette smokers, or were high-intensity cigarette smokers. We fit multivariable logistic regression models among baseline noncigarette smokers to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with subsequent cigarette smoking initiation and current cigarette smoking, accounting for established sociodemographic and behavioral risk factors. We fit similarly specified multivariable ordinal logistic regression models to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with high-intensity cigarette smoking at follow-up. EXPOSURES Water pipe tobacco smoking and the use of snus at baseline. MAIN OUTCOMES AND MEASURES Among baseline noncigarette smokers, cigarette smoking initiation, current (past 30 days) cigarette smoking at follow-up, and the intensity of cigarette smoking at follow-up. RESULTS Among 1596 respondents, 1048 had never smoked cigarettes at baseline, of whom 71 had smoked water pipe tobacco and 20 had used snus at baseline. At follow-up, accounting for behavioral and sociodemographic risk factors, baseline water pipe tobacco smoking and snus use were independently associated with cigarette smoking initiation (adjusted odds ratios: 2.56; 95% CI, 1.464.47 and 3.73; 95% CI, 1.439.76, respectively), current cigarette smoking (adjusted odds ratios: 2.48; 95%CI, 1.016.06 and 6.19; 95% CI, 1.8620.56, respectively), and higher intensity of cigarette smoking (adjusted proportional odds ratios: 2.55; 95%CI, 1.484.38 and 4.45; 95%CI, 1.7511.27, respectively). CONCLUSIONS AND RELEVANCE Water pipe tobacco smoking and the use of snus independently predicted the onset of cigarette smoking and current cigarette smoking at follow-up. Comprehensive Food and Drug Administration regulation of these tobacco products may limit their appeal to youth and curb the onset of cigarette smoking. PMID:26461999

    From the early 1980s to the present, neoliberal doctrine has called for government policies of privatization, funding cutbacks, and deregulation of public health and other domestic social programs in the belief that the market rather than the public sector can best organize and distribute crucial societal services. Proponents of a neoliberal and deregulatory mixed approach of command and control and self-regulation argue this approach provides the most adequate means to conduct regulation in the legalistic and adversarial U.S. regulatory process. In April 1994, the Occupational Safety and Health Administration issued a proposed rule to eliminate tobacco smoking in most workplace rooms, arguing secondhand tobacco smoke annually killed up to 13,700 nonsmokers. The tobacco industry purposely delayed public hearing procedures (later halted altogether by Congress and the president) primarily to advance unhindered private property rights and profits rather than submitting to a public command-and-control regulatory framework to reduce deaths due to secondhand tobacco smoke.

    A simulation model is developed for Vietnam to project smoking prevalence and associated premature mortality. The model examines independently and as a package the effects of five types of tobacco control policies: tax increases, clean air laws, mass media campaigns, advertising bans, and youth access policies. Predictions suggest that the largest reductions in smoking rates will result from implementing a comprehensive tobacco control policy package. Significant inroads may be achieved through tax increases. A media campaign along with programs to publicize and enforce clean air laws, advertising bans and youth access laws would further reduce smoking rates. Tobacco control policies have the potential to make large dents in smoking rates, which in turn could lead to many lives saved. In the absence of these measures, deaths from smoking will increase. The model also helps to identify information gaps pertinent both to modeling and policy-making. PMID:16182422

    Background Establishments dedicated to hookah tobacco smoking have recently proliferated and helped introduce hookah use to U.S. communities. Purpose To conduct a comprehensive, qualitative assessment of websites promoting these establishments. Methods In June 2009, a systematic search process was initiated to access the universe of websites representing major hookah tobacco smoking establishments. In 20092010, codebook development followed an iterative paradigm involving three researchers and resulted in a final codebook consisting of 36 codes within eight categories. After two independent coders had nearly perfect agreement (Cohens ?=0.93) on double-coding the data in the first 20% of sites, the coders divided the remaining sites and coded them independently. A thematic approach to the synthesis of findings and selection of exemplary quotations was used. Results The search yielded a sample of 144 websites originating from states in all U.S. regions. Among the hookah establishments promoted on the websites, 79% served food and 41% served alcohol. Of the websites, none required age verification, <1% included a tobacco-related warning on the first page, and 4% included a warning on any page. Although mention of the word tobacco was relatively uncommon (appearing on the first page of only 26% sites and on any page of 58% of sites), the promotion of flavorings, pleasure, relaxation, product quality, and cultural and social aspects of hookah smoking was common. Conclusions Websites may play a role in enhancing or propagating misinformation related to hookah tobacco smoking. Health education and policy measures may be valuable in countering this misinformation. PMID:22261211

    Objectives Waterpipe smoking is highly prevalent among university students, and has been increasing in popularity despite mounting evidence showing it is harmful to health. The aim of this study was to measure preferences for waterpipe smoking and determine which product characteristics are most important to smokers. Setting A large university in the Southeastern USA. Participants Adult waterpipe smokers attending the university (N=367). Design Participants completed an Internet-based discrete choice experiment to reveal their preferences for, and trade-offs between, the attributes of hypothetical waterpipe smoking sessions. Participants were presented with waterpipe lounge menus, each with three fruit-flavoured options and one tobacco flavoured option, in addition to an opt out option. Nicotine content and price were provided for each choice. Participants were randomised to either receive menus with a text-only health-warning message or no message. Outcome measures Multinomial and nested logit models were used to estimate the impact on consumer choice of attributes and between-subject assignment of health warnings respectively. Results On average, participants preferred fruit-flavoured varieties to tobacco flavour. They were averse to options labelled with higher nicotine content. Females and non-smokers of cigarettes were more likely than their counterparts to prefer flavoured and nicotine-free varieties. Participants exposed to a health warning were more likely to opt out. Conclusions Fruit-flavoured tobacco and lower nicotine content labels, two strategies widely used by the industry, increase the demand for waterpipe smoking among young adults. Waterpipe-specific regulation should limit the availability of flavoured waterpipe tobacco and require accurate labelling of constituents. Waterpipe-specific tobacco control regulation, along with research to inform policy, is required to curb this emerging public health threat. PMID:26353876

    Background Tobacco control effort should be first started in people that are looked upon as role models for the general population. We aimed to determine the knowledge, attitude, and behavior of religious officials towards smoking and the new tobacco law. Method The study group was comprised of 492 Imams and 149 Quran course instructors working in Kahramanmaras city of Turkey, 641 religious officials in total, and our survey form was applied on 406 (63.3%) of those religious officials who agreed to participate in the study. Results Twenty-eight (6.9%) participants were current smokers and 35 (8.6%) were ex-smokers. 99.8% of the religious officials believed that smoking was harmful and/or prohibited in terms of religion. While 43.6% respondents thought smoking was "haram" (forbidden by Islam), 56.2% believed it was "makruh" (something regarded as reprehensible, though not forbidden by God according to Islam). 85.2% of the participants were aware of the recent tobacco law. 55.5% of the respondents, who were aware of the recent tobacco law, evaluated their knowledge level on the law as adequate, whereas 44.5% evaluated it as inadequate 92.4% of the participants noted that religious officials should play active roles in tobacco control effort. Conclusion Smoking rate among religious officials is much lower than that of general public. In order to help religious officials to take a more active role on this issue, they should be trained on the subject and appropriate platforms should be established. PMID:21797994

    A brief bout of aerobic exercise (e.g. stationary bicycle) has been shown to result in an acute reduction in tobacco withdrawal symptoms and cravings in abstinent smokers. However, aerobic exercise is often not practical and it is of interest to examine whether non-aerobic exercise has a similar effect. We investigated whether isometric exercise (involving muscular contractions against resistance without movement, e.g. placing the palms of the hands together and pushing) reduces desire to smoke and tobacco withdrawal symptoms. Following overnight abstinence smokers were randomized to 5-min of: isometric exercises (n = 20), body scanning (focusing attention on sensations in different areas of the body, n = 20, control), or sitting passively (n = 20, control). Desire to smoke and tobacco withdrawal symptoms ('irritable', 'depressed', 'stressed', 'tense', 'restless' and 'poor concentration') were rated at baseline, immediately post-intervention, and 5-, 10-, 15- and 20-min post-intervention. Isometric exercise produced a significantly greater reduction in desire to smoke versus passive control at immediate post-intervention and 5-min post-intervention, relative to baseline (p < 0.05). Most withdrawal symptoms were significantly moderated by exercise versus controls at some point between 5- to 20-min post-intervention, relative to baseline (p < 0.05). Brief isometric exercise has potential for offering immediate relief from a desire to smoke. PMID:16389665

    Correlation analysis between main chemical constituents of tobacco leaves and endogenous harmful components in mainstream cigarette smoke was conducted. Leaf stalk positions exhibited a high relation with endogenous harmful components and hazard index (H). Upper stalk position leaves had greater release of 1-butanone,4-(methylnitrosoamino)-1-(3-pyridinyl)-(NNK), B[a]P, HCN, NH3 and phenol in mainstream cigarette smoke, and a higher hazard index than middle position leaves except for crotonaldehyde, which had greater release from middle position leaves. Different endogenous harmful components in mainstream cigarette smoke presented complicated correlation with main chemical constituents in tobacco. The same type of leaf chemical constituents presented different correlations with various endogenous harmful components in mainstream cigarette smoke. Cigarette hazard index showed significantly positive correlations with contents of nicotine, protein, total nitrogen, major polyphenols and organic acids, while significantly negative correlation with potassium and carbonaceous substances, such as total sugars, reducing sugars and starch. The results suggested that properly increasing potassium content and decreasing nitrogenous constituents in cured tobacco leaf may reduce the cigarette hazard index. PMID:26571664

    The objective of this study was to assess the relationship between exposure to state-sponsored anti-tobacco advertising and smoking cessation. Cessation rates in 2001 among a cohort of 2061 smokers who participated in the Community Intervention Trial for Smoking Cessation between 1988 and 1993 and completed a follow-up survey in 2001 were merged with 2000-01 television advertising exposure data from Nielsen Media Research. The relative risk for quitting was estimated to be 10% higher for every 5000 units of exposure to state anti-tobacco television advertising over the 2-year period, although this did not quite achieve statistical significance. The association was even larger among those who reported that the level of information in the media about the dangers of smoking had increased 'a lot' between 1993 and 2001 (RR = 1.19, 95% CI = 1.03-1.38). These data are consistent with the finding that increased exposure to state anti-tobacco media increases smoking cessation rates. PMID:16740679

The relative risk for quitting was estimated to be 10% higher for every 5000 units of exposure to state anti-tobacco television advertising over the 2-year period, although this did not quite achieve statistical significance. The association was even larger among those who reported that the level of information in the media about the dangers of smoking had increased 'a lot' between 1993 and 2001 (RR = 1.19, 95% CI = 1.03-1.38). These data are consistent with the finding that increased exposure to state anti-tobacco media increases smoking cessation rates. PMID:16286480

    A polyphenol-rich reagent, referred to as CSC, was isolated from cigarette smoke condensate and shown to prime purified human neutrophils. A mouse monoclonal anti-idiotypic antibody directed against the polyphenol-reactive determinants on a rabbit polyclonal anti-tobacco glycoprotein antibody was generated and shown to also prime neutrophils. After priming by CSC or tobacco anti-idiotypic antibody, there was a 2.5-fold to threefold increase in CD11b/18 expression and doubling of the number of formyl-methionyl-leucyl-phenylalanine receptors on the cells. The primed cells showed a twofold increase, compared with unprimed cells, in production of superoxide and release of neutrophil elastase after stimulation with formyl-methionyl-leucyl-phenylalanine. Neutrophils in peripheral blood of cigarette smokers have been shown to be primed and more responsive to activating agents. The priming effects attributed to whole cigarette smoke have been demonstrated in these studies using purified neutrophils and CSC or tobacco anti-idiotypic antibody. These studies are a first step in testing the hypothesis that the inflammatory process contributing to progression of chronic obstructive pulmonary disease in ex-smokers may be driven, in part, by tobacco anti-idiotypic antibodies. This hypothesis is novel and carries with it the implication of a heretofore unrecognized autoimmune component in the disease process manifested through production of anti-idiotypic antibodies with tobacco-like activity.

    Athens is a city with a serious air pollution problem which has existed for more than 20 years. To evaluate whether air pollution has affected lung cancer incidence (and hence, mortality) in the population of Athens the authors have compared standardized lung mortality between Athens and the rest of Greece taking into account the tobacco consumption trends in the respective populations and varying the postulated latency between 0 and 20 years. There is no evidence for an independent or interactive (with tobacco smoking) effect of air pollution on lung cancer mortality; the tobacco-adjusted mortality appears, if anything, lower in Athens than in the rest of Greece and the slopes of lung cancer mortality on tobacco consumption are almost identical in Athens and in the rest of Greece. By contrast the same data are compatible with a strong effect of tobacco smoking on lung cancer mortality, an effect which appears to involve not only the early carcinogenic stages but also some of the later ones. The results of the present analysis do not support the hypothesis that air pollution, at least in Athens until 1980, has increased the incidence of lung cancer to an extent large enough to be detectable in ecological correlation analyses. Nevertheless the inherent limitations of these methods indicate that their results should be interpreted with caution and only as a step toward the gradual understanding of a complex issue.

    The purpose of this study is to quantify the effect ofvarious design and operating parameters on smoking room performance.Twenty-eight experiments were conducted in a simulated smoking room witha smoking machine and an automatic door opener. Measurements were made ofair flows, pressures, temperatures, two particle-phase ETS tracers, twogas-phase ETS tracers, and sulfur hexafluoride. Quantification of leakageflows, the effect of these leaks on smoking room performance andnon-smoker exposure, and the relative importance of each leakagemechanism are presented. The results indicate that the first priority foran effective smoking room is to depressurize it with respect to adjoiningnon-smoking areas. Another important ETS leakage mechanism is the pumpingaction of the smoking room door. Substituting a sliding door for astandard swing-type door reduced this source of ETS leakagesignificantly. Measured results correlated well with model predictions(R2 = 0.82-0.99).

    Objective. Among current smokers, the proportion of Nondaily smokers is increasing. A better understanding of the characteristics and smoking behaviors of Nondaily smokers is needed. Methods. We analyzed data from the New York City (NYC) Community Health Survey to explore Nondaily smoking among NYC adults. Univariate analyses assessed changes in Nondaily smoking over time (2002–2010) and identified unique characteristics of Nondaily smokers; multivariable logistic regression analysis identified correlates of Nondaily smoking in 2010. Results. The proportion of smokers who engage in Nondaily smoking significantly increased between 2002 and 2010, from 31% to 36% (P = 0.05). A larger proportion of Nondaily smokers in 2010 were low income and made tax-avoidant cigarette purchases compared to 2002. Smoking behaviors significantly associated with Nondaily smoking in 2010 included smoking more than one hour after waking (AOR = 8.8, 95% CI (5.38–14.27)); buying “loosies” (AOR = 3.5, 95% CI (1.72–7.08)); attempting to quit (AOR = 2.3, 95% CI (1.36–3.96)). Conclusion. Nondaily smokers have changed over time and have characteristics distinct from daily smokers. Tobacco control efforts should be targeted towards “ready to quit” Nondaily smokers.

    Cigarette smoke is a complex mixture of more than 8000 smoke constituents. The quantification of selected mainstream smoke constituent yields is one of the methods to evaluating and comparing the performance of different products. Numerous regulatory and scientific advisory bodies have used cigarette smoke constituent yield data for reporting and product comparison purposes. For more than a decade limitations of the indiscriminate application of traditional statistical methods such as the t-test for differences in comparative smoke constituent yield assessments lacking a specific study design, have been highlighted. In the present study, the variability of smoke constituent yields is demonstrated with data obtained under the ISO smoking regime for the Kentucky reference cigarette 3R4F and one commercial brand, analyzed on several occasions between 2007 and 2014. Specifically it is shown that statistically significant differences in the yields of selected smoke constituents do not readily translate to differences between products, and that tolerances need to be defined. To this end, two approaches have been proposed in the literature--minimal detectable differences, and the statistical equivalence. It is illustrated how both approaches provide more meaningful comparison outcomes than the statistical t-test for differences. The present study provides considerations relevant for comparative tobacco product assessments both in the scientific and regulatory contexts. PMID:26140819

    There is systematic decrease in the age of tobacco, alcohol and drug initiation in Poland among children and adolescents. Education concerning damage caused by smoking tobacco drinking alcohol and taking drugs, if started in due course, is of essence when it comes to the inhibition of these unfavourable phenomena. The aim of this work was to recognise the participation of smokers, people who drink alcohol and take drugs among students of junior high school as well as checking the dependency between early tobacco initiation and taking to drugs and alcohol among the youth. In March 2014, 288 students of 1-3 grades were included in the study of some selected junior high schools from the Moniecki region in Podlaskie voivodeship. While collecting empirical material, anonymous survey was carried out including 35 questions. Students were asked to fill it in freely during a lesson. In order to elaborate the collected data, descriptive meth, ods were used as well as methods of statistical interference. 163 women (56.6%) and 125 men (43.4%) were included in the survey. The most numerous group consisted of respondents at the age of 15 (40.1%) In the surveyed group, 100 students (34.7%) admitted to smoking at least one cigarette in their life. 6.3% of the respondents (18 people) smoked daily, whereas 9.0% (26 people) claimed they smoked occasionally. Majority of the surveyed people (51%, 147 people) answered that they had already drunk alcohol. 2.4% of the respondents (7 people) declared drinking daily whereas 18.4% (53 people) claimed to be drinking occasionally. Every tenth junior high school student stated the had used drugs at least once in their life (10.1%, 29 people). Despite the law in Poland prohibiting drug possession and trade as well as alcohol and tobacco purchase and consumption among minors, frequency of drinking alcohol, smoking cigarette, and using drugs was high among the junior high school students.

    Tobacco taxation is an essential component of a comprehensive tobacco control strategy. However, to fully realize the benefits it is vital to understand the impact of increased taxes among high-risk subpopulations. Are they influenced to the same extent as the general population? Do they need additional measures to influence smoking behavior? The objectives of this study were to synthesize the evidence regarding differential effects of taxation and price on smoking in: youth, young adults, persons of low socio-economic status, with dual diagnoses, heavy/long-term smokers, and Aboriginal people. Using a better practices approach, a knowledge synthesis was conducted using a systematic review of the literature and an expert advisory panel. Experts were involved in developing the study plan, discussing findings, developing policy recommendations, and identifying priorities for future research. Most studies found that raising cigarette prices through increased taxes is a highly effective measure for reducing smoking among youth, young adults, and persons of low socioeconomic status. However, there is a striking lack of evidence about the impact of increasing cigarette prices on smoking behavior in heavy/long-term smokers, persons with a dual diagnosis and Aboriginals. Given their high prevalence of smoking, urgent attention is needed to develop effective policies for the six subpopulations reviewed. These findings will be of value to policy-makers and researchers in their efforts to improve the effectiveness of tobacco control measures, especially with subpopulations at most risk. Although specific studies are needed, tobacco taxation is a key policy measure for driving success. PMID:22163198

    The aim of the post-graduate degree course on tobacco and smoking cessation is to train professionals who have dedicated themselves to the fight against tobacco and smoking. An educational assessment of the degree programme was carried out in order to evaluate its impact on practice. A questionnaire was mailed to 60 students registered in the programme at Strasbourg University between 1997 and 2002 (with a response rate of 71.6%). The evaluation was able to shed light on the strengths and weaknesses of the teaching in the programme and the level of student satisfaction. The tobacco control and smoking cessation interventions of the students before and after completing the course were compared in order to assess the impact on their professional practice. The programme's participants came from a variety of professions including medical doctors (74.4%), paramedical staff (16.3%) and other professions (6.9%). The students acknowledged the course's high level of quality (the teachers were appreciated, and the programme was comprehensive). The structure of the course was operational; however, the students admitted that they felt that the practical application and the interactive aspects of the learning (such as case studies, role playing, training in a specific smoking cessation intervention were insufficient. They also noted a lack of emphasis on treatments that do not rely on pharmacotherapy such as behavioural therapy and psychological support. Tobacco cessation related problems or side effects of quitting like weight gain, anxiety or insomnia were not appropriately developed. The majority of students were very satisfied with the theoretical basis of the curriculum and with their internship in a tobacco cessation consultation intervention. Today, 69% of the students trained are working in smoking cessation and tobacco control. They have been able to diversify their activities, going from prevention to tobacco cessation, and vice versa. Course tracks focusing on pregnant women, adolescents and behavioural therapies have now been introduced into the degree programme. In terms of further investing in the improvement of skills and competencies, the programme could better respond to the students' needs by taking into account the development of interactive teaching methods such as role playing and workshops.

    Background In Britain, the tobacco industry segments cigarettes into four price categories—premium, mid-price, economy and ultra-low-price (ULP). Our previous work shows that tobacco companies have kept ULP prices stable in real terms. Roll your own (RYO) tobacco remains cheaper still. Methods Analysis of 2001–08 General Household Survey data to examine trends in use of these cheap products and, using logistic regression, the profile of users of these products. Results Among smokers, the proportion using cheap products (economy, ULP and RYO combined) increased significantly in almost all age groups and geographic areas. Increases were most marked in under 24 year olds, 76% of whom smoked cheap cigarettes by 2008. All cheap products were more commonly used in lower socio-economic groups. Men and younger smokers were more likely to smoke RYO while women smoked economy brands. Smokers outside London and the South East of England were more likely to smoke some form of cheap tobacco even once socio-economic differences were accounted for. Conclusions This paper demonstrates that cheap tobacco use is increasing among young and disadvantaged smokers compromising declines in population smoking prevalence. Thus, tobacco industry pricing appears to play a key role in explaining smoking patterns and inequalities in smoking. PMID:25118219

    Background Neighbourhood retailing of tobacco products has been implicated in affecting smoking prevalence rates. Long-term smoking usually begins in adolescence and tobacco control strategies have often focused on regulating child spaces, such as areas in proximity to schools. This cross-sectional study examines the association between adolescent smoking behaviour and tobacco retail outlet density around home and school environments in Scotland. Methods Data detailing the geographic location of every outlet registered to sell tobacco products in Scotland were acquired from the Scottish Tobacco Retailers Register and used to create a retail outlet density measure for every postcode. This measure was joined to individual responses of the Scottish Schools Adolescent Lifestyle and Substance Use Survey (n=20?446). Using logistic regression models, we explored the association between the density of retailers, around both home and school address, and smoking behaviours. Results Those living in the areas of highest density of retailers around the home environment had 53% higher odds of reporting having ever smoked (95% CI 1.27 to 1.85, p<0.001) and 47% higher odds of reporting current smoking (95% CI 1.13 to 1.91 p<0.01). Conversely, those attending schools in areas of highest retail density had lower odds of having ever smoked (OR 0.66, 95% CI 0.50 to 0.86 p<0.01) and lower odds of current smoking (OR 0.75, 95% CI 0.59 to 0.95, p<0.05). Conclusions The density of tobacco retail outlets in residential neighbourhoods is associated with increased odds of both ever smoked and current smoking among adolescents in Scotland. Policymakers may be advised to focus on reducing the overall density of tobacco outlets, rather than concentrating on child spaces. PMID:25370699

    This study examined educational differences in associations of noticing anti-tobacco information with smoking-related attitudes and quit intentions among adult smokers. Longitudinal data (N = 7571) from two waves of six countries of the International Tobacco Control (ITC) Europe Surveys were included. Generalized estimating equation analyses and multiple linear and logistic regression analyses were conducted. Higher educated smokers noticed anti-tobacco information slightly more often than lower educated smokers (F(2) = 25.78, P < 0.001). Noticing anti-tobacco information was associated with more negative smoking-related attitudes (? = 0.05, P < 0.001) and more quit intentions (OR = 1.08, P < 0.001). Among smokers without a quit intention at baseline, a positive association was found for noticing anti-tobacco information at baseline with follow-up quit intention (OR = 1.14, P = 0.003). No other longitudinal associations were found. No educational differences were found in the association of noticing anti-tobacco information with smoking-related attitudes but associations with quit intentions were found only among low (OR = 1.12, P = 0.001) and high educated respondents (OR = 1.11, P < 0.001) and not among moderate educated respondents (OR = 1.02, P = 0.43). Noticing anti-tobacco information may positively influence quit intentions and possibly smoking-related attitudes. Lower educated smokers were as likely to be influenced by anti-tobacco information as higher educated smokers but noticed anti-tobacco information less often; increasing reach of anti-tobacco information may increase impact in this group.

    The association between maternal smoking and preterm birth (PTB) has been known for more than 50 years but the effect of passive smoking is controversial. This retrospective cohort study in Bristol, United Kingdom, examines the effect of environmental tobacco smoke exposure (ETSE) on gestational age at delivery, birth weight, PTB, and being small-for-gestational age (SGA). Environmental tobacco smoke exposure was defined by either self-report or exhaled carbon monoxide (eCO) levels, and exposed women were compared with unexposed controls. Two models were used: The first included all women with adjustment for maternal smoking, and the second considered nonsmokers alone. Both models were further adjusted for maternal age, body mass index, parity, ethnicity, employment status, socioeconomic position, asthma, preeclampsia, and offspring sex. Logistic regression and likelihood ratio tests were used to test for any association between exposure and the binary outcomes (PTB and SGA), while linear regression and F tests were used to test for associations between exposure and the continuous outcomes. There were 13 359 deliveries in 2012 to 2014, with complete data for 5066 and 4793 women in the self-reported and eCO-measured exposure groups, respectively. Self-reported exposure was associated with earlier delivery (-0.19 weeks; 95% confidence interval [CI]: -0.32 to -0.05) and reduced birth weight (-56 g, 95% CI: -97 to -16 g) but no increase in the risk of PTB or SGA. There was no evidence for an association between eCO-measured exposure and any of the outcome measures. This information is important when advising women and their families and adds further support to continued public health efforts to reduce exposure to tobacco smoke. PMID:26507870

    Background Quitting tobacco or alcohol use has been reported to reduce the head and neck cancer risk in previous studies. However, it is unclear how many years must pass following cessation of these habits before the risk is reduced, and whether the risk ultimately declines to the level of never smokers or never drinkers. Methods We pooled individual-level data from casecontrol studies in the International Head and Neck Cancer Epidemiology Consortium. Data were available from 13 studies on drinking cessation (9167 cases and 12 593 controls), and from 17 studies on smoking cessation (12 040 cases and 16 884 controls). We estimated the effect of quitting smoking and drinking on the risk of head and neck cancer and its subsites, by calculating odds ratios (ORs) using logistic regression models. Results Quitting tobacco smoking for 14 years resulted in a head and neck cancer risk reduction [OR 0.70, confidence interval (CI) 0.610.81 compared with current smoking], with the risk reduction due to smoking cessation after ?20 years (OR 0.23, CI 0.180.31), reaching the level of never smokers. For alcohol use, a beneficial effect on the risk of head and neck cancer was only observed after ?20 years of quitting (OR 0.60, CI 0.400.89 compared with current drinking), reaching the level of never drinkers. Conclusions Our results support that cessation of tobacco smoking and cessation of alcohol drinking protect against the development of head and neck cancer. PMID:19805488

    Objective To determine what the tobacco industry knew about menthol's relation to smoking cessation behaviour. Methods A snowball sampling design was used to systematically search the Legacy Tobacco Documents Library (LTDL) (http://legacy.library.ucsf.edu) between 15 May to 1 August 2010. Of the approximately 11 million documents available in the LTDL, the iterative searches returned tens of thousands of results. A final collection of 509 documents relevant to 1 or more of the research questions were qualitatively analysed, as follows: (1) perceived sensory and taste rewards of menthol and potential relation to quitting; and (2) motivation to quit among menthol users. Results Menthol's cooling and anaesthetic effects mask the short-term negative physiological effects of smoking such as throat pain, burning and cough. This provides superficial physical relief as well as psychological assurance against concerns about the health dangers of smoking that would otherwise motivate smokers to quit. Menthol smokers, particularly women, perceive the minty aroma of menthol cigarettes to be more socially acceptable than non-menthol cigarettes. Discussion Consumers believe menthol's sensory effects equate to health protections and that menthol cigarettes are more socially acceptable than non-menthol cigarettes. Menthol in cigarettes may encourage experimenters who find non-mentholated cigarettes too harsh, including young or inexperienced users, to progress to regular smoking rather than quitting, and may lessen the motivation to quit among established menthol smokers. The perception of menthol cigarettes as more socially acceptable lessens the impact of smoking denormalisation on quitting motivation. Menthol makes cigarettes easier and more palatable to smoke and less desirable to quit among established smokers. Fewer smokers quitting contributes to the incidence of tobacco-related diseases.

    1994-10-01

    The American Stop Smoking Intervention Study for Cancer Prevention (ASSIST) is a collaborative effort of the National Cancer Institute, the American Cancer Society, state health departments, and other public and private organizations to develop comprehensive tobacco use control programs in 17 states. The two main goals of the project are to reduce adult smoking prevalence to 15% or less and to reduce the rates of smoking initiation among adolescents by 50% by the year 2000. There is strong consensus within the tobacco-control field of what needs to be done to accomplish these goals. The key elements of a comprehensive tobacco control effort include (1) an excise tax policy based on raising the real price of tobacco, (2) a ban on all forms of tobacco advertising and promotion, (3) product regulation to reduce the harmful constituents found in tobacco and enforce the use of strong and prominent package warnings, (4) the enactment of policies that protect nonsmokers from inhaling tobacco smoke, (5) comprehensive efforts to eliminate minors' access to tobacco products, (6) ongoing and adequately funded efforts to educate the public about the harmful effects of tobacco, (7) the availability of cessation assistance to persons interested in discontinuing the use of tobacco, and (8) the ending of all financial assistance to the tobacco-growing industry. Because older Americans represent a growing and political influential segment of our society, the enactment of effective tobacco control policies depends in part on generating support for such measures among older citizens. This article outlines several ways in which organizations such as American Association of Retired Persons and the American Cancer Society can work together to advocate meaningful tobacco control policies (e.g., higher excise taxes, clean indoor air laws, etc.).

    Baker, Richard R; Massey, Eian D; Smith, Graham

    2004-01-01

    This paper presents an overview of a series of studies designed to assess the influence of 482 tobacco ingredients on cigarette smoke chemistry and toxicity. The studies are: pyrolysis of the ingredients; influence of the ingredients on smoke constituents believed by regulatory authorities to be relevant to smoking-related diseases ("Hoffmann analytes"); influence of the ingredients on in vitro genotoxicity and cytotoxicity of smoke partiulate matter; and influence of the ingredients on the inhalation toxicity of smoke. The present paper brings the salient features of these studies together. A pyrolysis technique has been developed which, as far as practicably possible, mimics the combustion conditions inside a burning cigarette. The results from 291 single-substance ingredients indicate that almost a third would transfer out of the cigarette burning zone at least 99% intact (i.e. less than 1% pyrolysis), and almost two thirds would transfer at least 95% intact. Of the ingredients that underwent some degree of pyrolysis, a few "Hoffmann analytes" were detected amongst the pyrolysis products of 19 ingredients. Taking into account maximum use levels, their maximum pyrolysis levels were generally small and often insignificant compared to the levels typically present in smoke. Possible exceptions were acetaldehyde and benzene from the pyrolysis of malic acid. However, subsequent smoke chemistry studies indicated that the maximum levels predicted from pyrolysis of this involatile substance were overestimated, suggesting that malic acid does not undergo complete pyrolysis in the burning cigarette and/or generates acetaldehyde and benzene at similar rates to that of tobacco on a per weight basis. When added to tobacco, many of the ingredient mixtures produced no significant effect on the levels of many of the "Hoffmann analytes" in smoke, while some produced increases or decreases relative to the relevant control cigarettes. The study has concentrated on the increases. Many of the differences were found to be not significant when the long-term variability of the analytical methodology was taken into account. However, even taking this into account, the smoke formaldehyde levels in two of the test cigarettes were significantly increased relative to their controls, by up to 26 microg (73%). These increases are likely to be due to the pyrolysis of sugars, cellulose and other polysaccharide materials. The activity of smoke particulate matter from cigarettes containing tobacco ingredients has been determined with three in vitro bioassays, two for genotoxicity and one for cytotoxicity. These were the Ames test, the mammalian cell micronucleus assay, and the neutral red uptake cytotoxicity assay. Within the sensitivity and specificity of these bioassays, the specific activity of the cigarette smoke particulate matter was not changed by the addition of ingredients to the cigarette. Three 90-day sub-chronic inhalation studies have been undertaken and histopathological and histomorphometric assessments made within the respiratory tracts of animals exposed to smoke from cigarettes containing the various ingredient mixtures and their control cigarettes. The response due to tobacco smoke exposure was not distinguishable between the test and control cigarettes, indicating that the presence of the ingredients had made no discernable differences to the type and severity of the treatment-related changes.

    Introduction To protect residents from tobacco smoke exposure (TSE), the Boston Housing Authority (BHA) prohibited smoking in BHA-owned apartments beginning in 2012. Our goal was to determine if the smoke-free policy reduced TSE for non-smoking BHA residents. Methods We compared TSE before the smoke-free policy (2012) and one year later among BHA residents as well as residents of the neighboring Cambridge Housing Authority (CHA) where no such policy was in place. Participants were a convenience sample of adult non-smoking BHA and CHA residents cohabitating with only non-smokers. Main outcomes were 7-day airborne nicotine in participants apartments; residents saliva cotinine; and residents self-reported TSE. Results We enrolled 287 confirmed non-smokers (192 BHA, 95 CHA). Seventy-nine percent (229) were assessed at follow-up. At baseline, apartment and resident TSE were high in both housing authorities (detectable airborne nicotine: 46% BHA, 48% CHA; detectable saliva cotinine: 49% BHA, 70% CHA). At follow-up there were significant but similar declines in nicotine in both sites (detectable: -33% BHA, -39% CHA, p = 0.40). Detectable cotinine rose among BHA residents while declining among CHA participants (+17% BHA vs. -13% CHA, p = 0.002). Resident self-reported TSE within and outside of the housing environment decreased similarly for both BHA and CHA residents. Conclusions Apartment air nicotine decreased after the introduction of the smoke-free policy, though the decline may not have resulted from the policy. The BHA policy did not result in reduced individual-level TSE. Unmeasured sources of non-residential TSE may have contributed to BHA residents cotinine levels. PMID:26360258

    Early (P50) and late (P200) auditory sensory gating were assessed in low and high schizotypal personality groups using Raine's Schizotypal Personality Questionnaire. We also assessed the impact of smoking as it relates to low and high schizotypal personalities. Low and high schizoptypal personality groups were divided into subgroups of participants who either smoked or did not smoke tobacco cigarettes. Participants were 39 (18 men) right-handed undergraduates. Using a paired-tone paradigm (40 pairs, 70 dB, 1000 Hz), smokers were tested while abstaining from smoking, and 5 min after smoking. Non-smokers were tested similarly without smoking. Midline and hemispheric sites were evaluated at frontal (F3/Fz/F4), fronto-central (FC3/FCz/FC4), central (C3/Cz/C4), centro-parietal (CP3/CPz/CP4), and parietal (P3/Pz/P4) regions. P50 sensory gating was better at midline sites than left/right hemispheric sites, whereas there was no difference in activation with respect to location for P200 sensory gating. Cz had better P50 sensory gating than other midline regions, whereas Fz, FCz and Cz had better P200 sensory gating than CPz and Pz. Hemispheric comparisons were made. At the central region for non-smokers, high schizotypys showed poorer P50 sensory gating than low schizotypys. Among low schizotypys, smokers showed poorer P50 sensory gating than non-smokers at the fronto-central and central regions smokers showed better P200 sensory gating than non-smokers at the central region. Smoking had no acute impact on either early (P50) or late (P200) sensory gating. Our data support the notion that early sensory gating and late sensory gating represent different sensory gating mechanisms with respect to low and high schizotypy personalities. Individual differences in early and late sensory gating need further investigation. PMID:17292483

  16. Detection of chronic respiratory bronchiolitis in oxidant-exposed populations: Analogy to tobacco smoke exposure

    Studies in nonhuman primates indicate that one pathophysiologic consequence of ozone exposure is chronic bronchiolitis in terminal bronchioles. Modeling dosimetry suggests that a similar phenomenon is possible in humans. These findings may constitute an important analogy to the respiratory bronchiolitis that is associated with tobacco smoking in young adults. This analogy could form the basis for future research related to chronic respiratory health effects of ozone. The smoking data are reviewed and several research strategies are proposed that will be developed more fully in subsequent articles in this volume. 15 refs.

    Water pipe smoking (WPS) is increasing in popularity and prevalence worldwide. Convincing data suggest that the toxicants in WPS are similar to that of cigarette smoke. However, the underlying pathophysiologic mechanisms related to the early pulmonary events of WPS exposure are not understood. Here, we evaluated the early pulmonary events of nose-only exposure to mainstream WPS generated by commercially available honey flavored "moasel" tobacco. BALB/c mice were exposed to WPS 30min/day for 5days. Control mice were exposed using the same protocol to atmospheric air only. We measured airway resistance using forced oscillation technique, and pulmonary inflammation was evaluated histopathologically and by biochemical analysis of bronchoalveolar lavage (BAL) fluid and lung tissue. Lung oxidative stress was evaluated biochemically by measuring the level of reactive oxygen species (ROS), lipid peroxidation (LPO), reduced glutathione (GSH), catalase, and superoxide dismutase (SOD). Mice exposed to WPS showed a significant increase in the number of neutrophils (P<0.05) and lymphocytes (P<0.001). Moreover, total protein (P<0.05), lactate dehydrogenase (P<0.005), and endothelin (P<0.05) levels were augmented in bronchoalveolar lavage fluid. Tumor necrosis factor ? (P<0.005) and interleukin 6 (P<0.05) concentrations were significantly increased in lung following the exposure to WPS. Both ROS (P<0.05) and LPO (P<0.005) in lung tissue were significantly increased, whereas the level and activity of antioxidants including GSH (P<0.0001), catalase (P<0.005), and SOD (P<0.0001) were significantly decreased after WPS exposure, indicating the occurrence of oxidative stress. In contrast, airway resistance was not increased in WPS exposure. We conclude that subacute, nose-only exposure to WPS causes lung inflammation and oxidative stress without affecting pulmonary function suggesting that inflammation and oxidative stress are early markers of WPS exposure that precede airway dysfunction.
