    2009-01-01

    Introduction Tobacco cigarette smoking a well-known cause of cancer and other diseases. Hookah smoking is another form of tobacco use that has rapidly spread in the United State and Europe. This study assessed beliefs about the harmfulness of smoking hookah. Methods We surveyed hookah users in all cafes that provided hookah to its customers in downtown San Diego, California and nearby areas. A total of 235 hookah users participated in this study. Results Average age of study participants was 22 years, 57% were males, and 72% were not cigarette smokers. Whites were more likely to use hookah than the other ethnic groups (33%), older hookah users (26-35 years) were mostly males, and mint flavor of hookah tobacco was the most popular among a wide variety of flavors (23%). There was no significant difference in gender in relation to the wrong perception that hookah is less harmful than cigarettes, but those of Asian ethnicity were much less likely than other ethnic groups to believe that hookah is less harmful than cigarettes. More frequent users of hookah were more likely to believe that hookah is less harmful than cigarettes. The majority of hookah users (58.3%) believe hookah is less harmful than cigarette smoking. Discussion Compared to cigarettes, there appears to be a lack of knowledge about the harmfulness of smoking hookah among users regardless of their demographic background. Education about the harmfulness of smoking hookah and policies to limit its use should be implemented to prevent the spread of this new form of tobacco use. PMID:20021672

    The practice of waterpipe smoking (hookah) has rapidly increased in popularity among young adults yet burgeoning research suggests that its use is associated with nicotine dependence and other negative smoking-related health consequences. Moreover, descriptive studies indicate that consumers may hold the belief that hookah smoking is safer than smoking cigarettes. The current study extended previous work by conducting a comprehensive assessment of patterns and contexts of hookah use, psychological correlates of use, co-occurring substance use as well as social norms and health perceptions surrounding the practice. Participants were 143 ethnically diverse undergraduate students at a large urban US university. Approximately half of the sample (48%) reported life-time use of hookah and 22% reported use within the past 30days. Relative to cigarette smoking, hookah smoking was associated with less perceived harm and addiction potential and higher social approval. Participants who reported life-time hookah use, as compared to those who did not, perceived less associated harm, had a greater number of friends who had tried and approved of hookah, were more likely to use cigarettes, marijuana, and alcohol and in higher frequencies and quantities and were at higher risk for problem tobacco and alcohol use. Among participants who were not current smokers, those with hookah experience were more likely to endorse intent to try a cigarette soon. Hookah users did not differ from non-users on measures of trait anxiety, depression and impulsivity though they were more likely to drink alcohol for coping, social and enhancement purposes than non-users. Implications are discussed for public health initiatives to educate young adults about the potential consequences of hookah smoking.

    We studied the carbon monoxide (CO) fractions in hookah and cigarette smoke, using a carbon monoxide micro smokerlyzer (model EC50, BEDFONT, U.K.). Mean carbon monoxide fractions (% by volume) of hookah smoke, using domestic charcoal were 0.38 +/- 0.07 (large hookah; unfiltered); 1.40 +/- 0.43 (small hookah; unfiltered); 0.34 +/- 0.06 (large hookah; filtered); 1.36 +/- 0.35 (small hookah; filtered) and 0.41 +/- 0.08 (cigarette smoke). The highest fractions were obtained with small size hookah and increase in size of hookah (i.e., volume of air in water base, fire bowl volume, pipe length, etc.) reduced the CO fraction significantly (P < 0.001). The fractions of cigarette lie between large and small hookah. The fractions vary slightly with different varieties of tobacco, e.g., CO fractions with Dera wala tobacco are significantly low (P < 0.05). Use of commercial charcoal gives significant rise in CO fractions (P < 0.001). Comparison of filtered and unfiltered smoke shows no significant difference in values. We conclude that the CO hazard is as high with hookah smoking as with cigarette smoking.

    Objective To examine hookah tobacco use, hookah lounge attendance, and facilitators and barriers to hookah lounge attendance. Methods A cross-sectional Web-based survey of a random sample of 1332 undergraduate students (Mean Age = 21.2 years) attending a United States university. Results The majority of respondents (72.8%) had ever smoked hookah tobacco, and 28% of those had ever smoked during adolescence. The majority of ever hookah smokers (81.5%) and a portion of never hookah smokers (20%) had ever been to a hookah lounge. The adjusted odds of ever visiting a hookah lounge were 2.1 times higher among participants who reported that the closest hookah lounge to the university was < 5 miles away than those who reported that the closest hookah lounge was ≥ 5 miles away. Facilitators of visiting hookah lounges included friends and close proximity of hookah lounges to campus; barriers included cost of smoking hookah, crowded lounges, and having to be 18 years old. Conclusion Youth are vulnerable to experimenting with hookah tobacco smoking. Hookah lounges provide patrons the opportunity to smoke hookah tobacco with smoker and non-smoker friends in entertaining settings. Our findings suggest that zoning laws and anti-hookah smoking legislation may help curb hookah uptake by prohibiting hookah lounges from opening in close proximity to universities, reducing the density of hookah lounges in cities, and raising the admission age for hookah lounges to 21 years.

    Background These days, hookah smoking has gained popularity among people in many communities, especially among youths and students, and more attention to this issue seems necessary. The purpose of this study was to determine the factors affecting hookah smoking among Sabzevar Azad University students. Methods This cross-sectional study was conducted on university students in Sabzevar, Iran in 2014. The questionnaire was developed and its validity and reliability were assessed. Three hundred six male students of Sabzevar Azad University were selected by simple random sampling and questionnaires were filled out by them. The collected data were analyzed by SPSS software and the Chi-Square and Independent-samples t-test. Results The results showed that 47.7% of the participants had a history of smoking hookah. The main factors affecting hookah smoking from participants’ point of view were: filling leisure time, availability of hookah, positive social appearance, friends’ invitation and relief from anxieties. Chi-Square tests showed that there was no significant relationship between fathers’ level of education (p=0.41), mothers’ level of education (p=0.46), fathers’ job (p=0.18), mothers’ job (p=0.53) and students’ current grade (p=0.41) with hookah smoking. The study showed significant relationship between present hookah smoking and awareness about complications of the hookah (p=0.01). Conclusion Interventions to reduce and quit hookah smoking among students should include several items, such as teaching problem-solving skills to fill leisure time properly and to deal with the temptation of hookah smoking, as well as teaching refusal skills at the invitation of friends for hookah.

    Hookah smoking has recently emerged as a popular alternative to cigarette smoking particularly among young adults and women. This study focused on the role of family members' smoking behaviours as a possible risk factor for initiation of hookah smoking in women. 36 in-depth interviews were conducted with Iranian women of diverse ages for understanding the factors contributing to the initiation of hookah smoking. Four main themes were identified from the data. This study focused on the role of family as a facilitator for hookah smoking initiation. The results of this study indicate that the entry of hookah into homes can be effective in the spread of hookah smoking among adult and young women, in three ways: Girls' participation in the preparation of hookah and the frequent observation of people who smoke hookah at home can be effective in hookah smoking initiation among young girls; the husband of a young woman has an important role in the initiation of smoking hookah; when parents invite children to smoke hookah at home, in order to protect them against public censure, the mother (a middle aged woman) may intend to start smoking hookah. Therefore, tobacco use prevention interventions should be focused on targeting the family as well.

    Hookah (water pipe) smoking is a major new understudied epidemic affecting youth. Because burning charcoal is used to heat the tobacco product, hookah smoke delivers not only nicotine but also large amounts of charcoal combustion products, including carbon-rich nanoparticles that constitute putative coronary vasoconstrictor stimuli and carbon monoxide, a known coronary vasodilator. We used myocardial contrast echocardiography perfusion imaging with intravenous lipid shelled microbubbles in young adult hookah smokers to determine the net effect of smoking hookah on myocardial blood flow. In 9 hookah smokers (age 27 ± 5 years, mean ± SD), we measured myocardial blood flow velocity (β), myocardial blood volume (A), myocardial blood flow (A × β) as well as myocardial oxygen consumption (MVO2) before and immediately after 30 minutes of ad lib hookah smoking. Myocardial blood flow did not decrease with hookah smoking but rather increased acutely (88 ± 10 to 120 ± 19 a.u./s, mean ± SE, p = 0.02), matching a mild increase in MVO2 (6.5 ± 0.3 to 7.6 ± 0.4 ml·minute(-1), p <0.001). This was manifested primarily by increased myocardial blood flow velocity (0.7 ± 0.1 to 0.9 ± 0.1 second(-1), p = 0.01) with unchanged myocardial blood volume (133 ± 7 to 137 ± 7 a.u., p = ns), the same pattern of coronary microvascular response seen with a low-dose β-adrenergic agonist. Indeed, with hookah, the increased MVO2 was accompanied by decreased heart rate variability, an indirect index of adrenergic overactivity, and eliminated by β-adrenergic blockade (i.v. propranolol). In conclusion, nanoparticle-enriched hookah smoke either is not an acute coronary vasoconstrictor stimulus or its vasoconstrictor effect is too weak to overcome the physiologic dilation of coronary microvessels matching mild cardiac β-adrenergic stimulation.

    2012-01-01

    Preventing youth smoking initiation is a priority for tobacco control programs, because most adult tobacco smokers become addicted during adolescence. Interventions that restrict the affordability, accessibility, and marketing of cigarettes have been effective in reducing youth cigarette smoking. However, increasing numbers of youth are smoking tobacco using hookahs. Predictors of smoking tobacco with hookahs are the same as those for smoking cigarettes. Established interventions that curb youth cigarette smoking should therefore be effective in reducing hookah use. Potential policy interventions include equalizing tobacco tax rates for all tobacco types, requiring warning labels on hookah tobacco and accurate labeling of product contents, extending the cigarette flavoring ban to hookah tobacco, enacting smoke-free air laws and removing exemptions for hookah lounges, and expanding shipping restrictions on tobacco products.

    Background An increase in hookah smoking is considered to be a serious health problem in societies withdifferent cigarette smoking patterns. Thus, determinants of increase in this behavior are needed to beidentified. This study aimed to review the articles related to the causes of hookah smoking in the society. Methods This study reviewed the scientific references of authentic databases and journals, including Web ofScience, PubMed, Iranian Databases, Elsevier, Embase, Scopus, MEDLINE, CINAHL, CDC, and WorldHealth Organization (WHO). Overall, 84 scientific studies conducted during 1990-2015 were collected. Findings Several studies on the prevalence of smoking hookah and its associated factors in the societysuggested that numerous factors played a role in interest in smoking hookah. The most common reasons forindividuals’ inclination to smoke hookah were positive viewpoints toward smoking hookah, wrong beliefsabout its low risks, presumed lack of addiction, social acceptance, ease of access, wrong cultural habits, andregulative weakness. Conclusion Evidence indicated that a large spectrum of individual and social factors was effective in variouslevels of hookah consumption. Besides, it seems that single-component interventions and those solely basedon individual factors could not result in effective prevention. On the other hand, interventions based onecological approaches are suggested in this regard. Overall, it is essential to focus on the exclusion of positiveviewpoints toward hookah, develop the ability to say “no,” relaxation, and resistance against temptations tosmoke hookah, culturalization, and regulation of strong laws.

    Introduction Hookah smoking is becoming increasingly popular among young adults and is often perceived as less harmful than cigarette use. Prior studies show that it is common for youth and young adults to network about substance use behaviors on social media. Social media messages about hookah could influence its use among young people. We explored normalization or discouragement of hookah smoking, and other common messages about hookah on Twitter. Methods From the full stream of tweets posted on Twitter from April 12, 2014, to May 10, 2014 (approximately 14.5 billion tweets), all tweets containing the terms hookah, hooka, shisha, or sheesha were collected (n = 358,523). The hookah tweets from Twitter users (tweeters) with high influence and followers were identified (n = 39,824) and a random sample of 5,000 tweets was taken (13% of tweets with high influence and followers). The sample of tweets was qualitatively coded for normalization (ie, makes hookah smoking seem common and normal or portrays positive experiences with smoking hookah) or discouragement of hookah smoking, and other common themes using crowdsourcing. Results Approximately 87% of the sample of tweets normalized hookah use, and 7% were against hookah or discouraged its use. Nearly half (46%) of tweets that normalized hookah indicated that the tweeter was smoking hookah or wanted to smoke hookah, and 19% were advertisements/promotions for hookah bars or products. Conclusion Educational campaigns about health harms from hookah use and policy changes regarding smoke-free air laws and tobacco advertising on the Internet may be useful to help offset the influence of pro-hookah messages seen on social media.

    Abstract Background Hookah smoking is growing in popularity especially among women but little is known about the determinants influencing on hookah smoking initiation. In order to address this emerging health risk, a qualitative study was conducted to explore the factors that contribute in the first hookah smoking trial by women. Methods This qualitative study was conducted during 2012 to 2013 in Tehran, Iran. Participants were recruited to represent diversity in smoking status, ethnicity, age groups and residence. Data was collected through in-depth individual interviews and was analyzed through content analysis. Results Four main themes were identified from the qualitative data including: Positive attitude toward hookah smoking; Social and family facilitators; Psychosocial needs and gaps and Sensory characteristic of hookah. Conclusion From this study, a variety of factors which contribute to the initiation of hookah smoking among women have been identified. Since one of the major causes of increased hookah smoking may be its ordinary use, all factors causing the ordinary use should be eliminated, and efforts should be made in opposition to hookah smoking promotions.

    Background: In Iranian women, the use of hookah is the most common method of tobacco smoking. This study aimed to find the role of psycho-social needs and gaps as a possible risk factor for hookah smoking initiation in women. Methods: This qualitative study was conducted during 2012–2013 in Tehran, Iran. Thirty-six women participated in the study. They were current or former users of hookah. Data were collected through in-depth individual interviews and was analyzed through content analysis. Results: Four main categories were identified from the data. This study focused on the category: Psycho-social needs and gaps. This category has five sub-categories which explain why women begin to smoke hookah including curiosity; desire for non-feminine, forbidden, and negative activities; need for amusement and recreation; for others: To show off; attract attention; satisfy and join others and protection. Conclusions: From this study, a variety of factors which contribute to the initiation of hookah smoking among women have been identified. Keeping young girls and women away from seemingly happy gatherings of hookah smokers; Providing appropriate recreational facilities for young women and training families on how to help their children in the event of a crisis-like intention to take up smoking behavior, can be some effective ways for reducing hookah smoking initiation among women.

    2016-01-01

    Introduction: Hookah smoking has seen a reemergence in popularity in the last 30 years, particularly in the young urban population. This study aimed to compare the prevalence of and the attitude and beliefs about hookah smoking of people with a medical background and compare it with people from a non-medical background. Materials and methods: An anonymous questionnaire with ten questions about various aspects of hookah smoking was formulated using Google forms®, which was then circulated via Facebook®, Whatsapp® and emails to the intended participants and all responses were recorded and analyzed. Results: The total number of respondents were 470. The number of respondents with a medical background was 45.31%. The percentage of the respondents with a medical background who smoked a hookah was 28.63%, while the same percentage of the respondents with a non-medical background was 63.42. The perception of hookah being less harmful than a cigarette was not found to be statistically different between the two groups. Respondents with a medical background were more ignorant of the presence or absence of tobacco in the hookah they smoked. The average duration of the hookah smoking habit, the frequency of its use per month, and the average lengths of the hookah smoking session were 3.52 years (95% CI of 3.21 to 3.82), 1.946 (95% CI 1.799 to 2.093), and 58.90 minutes (95% CI of 54.42 to 63.37), respectively. Conclusion: The knowledge about the ill effects of smokeless tobacco should be integrated into the structured teaching curriculum of undergraduate medical and dental courses as they prepare future physicians and dental surgeons for an anti-tobacco campaign.

    Background Water pipe tobacco smoking is spreading globally and is increasingly becoming popular in the United States, particularly among young people. While many perceive water pipe smoking to be relatively safe, clinical experimental studies indicate significant exposures to tobacco smoke carcinogens following water pipe use. We investigated biomarkers of nicotine intake and carcinogen exposure from water pipe smoking in the naturalistic setting of hookah bars. Methods Fifty-five experienced water pipe users were studied before and after smoking water pipe in their customary way in a hookah bar. Urine samples were analyzed for nicotine, cotinine, the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1- butanol (NNAL), and mercapturic acid metabolites of volatile organic compounds (VOCs). Results We found an average 73-fold increase in nicotine, 4-fold increase in cotinine, 2-fold increase in NNAL, and 14-91% increase in VOC mercapturic acid metabolites immediately following water pipe smoking. We saw moderate to high correlations between changes in tobacco-specific biomarkers (nicotine, cotinine, and NNAL) and several mercapturic acid metabolites of VOC. Conclusion Water pipe smoking in a hookah bar is associated with significant nicotine intake and carcinogen exposure. Impact Given the significant intake of nicotine and carcinogens, chronic water pipe use could place users at increased risk of cancer and other chronic diseases. PMID:24836469

    Background Use of a hookah (a type of water pipe) is a traditional way of smoking tobacco, particularly in the Middle East. In Turkey, its popularity has been growing in recent years, especially among young people. It is known that cigarette smoking has genotoxic effects and causes mutations, but no comprehensive study has been done on the genotoxic effects of hookah usage, particularly in Turkey. Material/Methods We collected peripheral blood/buccal smear samples from 30 subjects who did not smoke cigarettes but who regularly smoke a hookah an average of 2 times per week, and from 30 control subjects who had never smoked cigarettes or a hookah. Chromosome analyses were performed on the samples obtained from peripheral blood of each individual, 25 metaphase plaques were counted for each, and chromosome/chromatid breakage/gap parameters were evaluated. Micronucleus analysis was done on buccal smear samples and micronucleus/binucleus parameters were investigated by counting 2000 cells of each individual. Results Chromosome breakage ratios were found to be 0.64±0.86 and 0.46±0.71 in the study and control groups, respectively, while chromatid breakage ratios were 0.53±0.83 and 0.53±0.71; fragment ratios were 0.82±1.24 and 0.21±0.49 (p<0.05); and gap ratios were 0.57±0.83 and 0.18±0.53 (p<0.05), respectively. Micronucleus ratio was 6.03±2.06 and 4.43±2.27 (p<0.05) in the study and control groups, respectively, and binucleus ratios were 8.53±3.23 and 12.15±5.18, respectively (p<0.05). Conclusions Results of our study reveal significant statistical differences between the individuals who smoked hookah and those who did not in terms of fragment, gap, micronucleus, and binucleus parameters, suggesting that smoking a hookah may cause genotoxic effects.

    A hookah smoker who was treated for severe carbon monoxide poisoning with hyperbaric oxygen reported using a different type of charcoal prior to hospital admission, i.e., quick-light charcoal. This finding led to a study aimed at determining whether CO production differs between charcoals commonly used for hookah smoking, natural and quick-light. Our hypothesis was that quick-light charcoal produces significantly more CO than natural charcoal. A medium-sized hookah, activated charcoal filter, calibrated syringe, CO gas analyzer and infrared thermometer were assembled in series. A single 9-10 g briquette of either natural or quick-light charcoal was placed atop the hookah bowl and ignited. CO output (ppm) and temperature (degrees C) were measured in three-minute intervals over 90 minutes. The mean CO levels produced by quick-light charcoal over 90 minutes was significantly higher (3728 ± 2028) compared to natural charcoal (1730 ± 501 ppm, p = 0.016). However, the temperature was significantly greater when burning natural charcoal (292 ± 87) compared to quick-light charcoal (247 ± 92 degrees C, p = 0.013). The high levels of CO produced when using quick-light charcoals may be contributing to the increase in reported hospital admissions for severe CO poisoning.

    Introduction: We examined homes of hookah-only smokers and nonsmokers for levels of indoor air nicotine (a marker of secondhand smoke) and indoor surface nicotine (a marker of thirdhand smoke), child uptake of nicotine, the carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), and the toxicant acrolein by analyzing their corresponding metabolites cotinine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) and NNAL-glucuronides (total NNAL) and 3-hydroxypropylmercapturic acid. Methods: Data were collected at 3 home visits during a 7-day study period from a convenience sample of 24 households with a child 5 years or younger. Three child urine samples and 2 air and surface samples from the living room and the child bedroom were taken in homes of nonsmokers (n = 5) and hookah-only smokers (n = 19) comprised of daily hookah smokers (n = 8) and weekly/monthly hookah smokers (n = 11). Results: Nicotine levels in indoor air and on surfaces in the child bedrooms in homes of daily hookah smokers were significantly higher than in homes of nonsmokers. Uptake of nicotine, NNK, and acrolein in children living in daily hookah smoker homes was significantly higher than in children living in nonsmoker homes. Uptake of nicotine and NNK in children living in weekly/monthly hookah smoker homes was significantly higher than in children living in nonsmoker homes. Conclusions: Our data provide the first evidence for uptake of nicotine, the tobacco-specific lung carcinogen NNK, and the ciliatoxic and cardiotoxic agent acrolein in children living in homes of hookah smokers. Our findings suggest that daily and occasional hookah use in homes present a serious, emerging threat to children’s long-term health. PMID:24590387

    Background Hookah smoking has increased worldwide, especially among young people. Objectives The aim of the present study was to determine the prevalence of hookah use and related factors in a sample of Iranian students of medical sciences. Materials and Methods A cross-sectional study was conducted on 1992 randomly selected sample of students of Tehran University of Medical Sciences during 2012 - 2013. A multistage sampling method was used and anonymous structured questionnaires were distributed to the students of each selected class. Chi-square test, Fisher's exact test and multiple binary logistic regression analyses were performed and P < 0.05 was considered as a significance level. Results Lifetime, last year and last month prevalence rates of hookah smoking were 26.6% (95% CI: 24.7 - 28.6), 17.8% (95% CI: 16.1 - 19.5) and 8.9% (95% CI: 7.7 - 10.2), respectively. The results of logistic regression model showed that male gender [odds ratio (OR) = 2.8, 95% CI: 1.86 - 4.21], cigarette smoking in the past year (OR = 5.6, 95% CI: 3.21 - 9.83), alcohol use in the past year (OR = 7.4, 95% CI: 4.01 - 13.06), cigarette or hookah smoking in the family members (OR = 1.7, 95% CI: 1.13 - 2.51), cigarette or hookah smoking among friends (OR = 4.4, 95% CI: 2.69 - 7.33), alcohol use by friends in the past year (OR = 1.9, 95% CI: 1.20 - 3.14), and illicit substance use among friends (OR = 2.2, 95% CI: 1.22 - 4.05) were associated with hookah smoking. Conclusions The results of our study indicate a relatively high prevalence of hookah smoking among Iranian students. The findings emphasize the importance of planning preventive interventions by considering different high-risk behaviors simultaneously. PMID:27803724

  8. Hookah (Shisha, Narghile) Smoking and Environmental Tobacco Smoke (ETS). A Critical Review of the Relevant Literature and the Public Health Consequences

    2009-01-01

    Hookah (narghile, shisha, “water-pipe”) smoking is now seen by public health officials as a global tobacco epidemic. Cigarette Environmental Tobacco Smoke (ETS) is classically understood as a combination of Side-Stream Smoke (SSS) and Exhaled Main-Stream Smoke (EMSS), both diluted and aged. Some of the corresponding cigarette studies have served as the scientific basis for stringent legislation on indoor smoking across the world. Interestingly, one of the distinctive traits of the hookah device is that it generates almost no SSS. Indeed, its ETS is made up almost exclusively by the smoke exhaled by the smoker (EMSS), i.e. which has been filtered by the hookah at the level of the bowl, inside the water, along the hose and then by the smoker’s respiratory tract itself. The present paper reviews the sparse and scattered scientific evidence available about hookah EMSS and the corresponding inferences that can be drawn from the composition of cigarette EMSS. The reviewed literature shows that most of hookah ETS is made up of EMSS and that the latter qualitatively differs from MSS. Keeping in mind that the first victim of passive smoking is the active smoker her/himself, the toxicity of hookah ETS for non-smokers should not be overestimated and hyped in an unscientific way.

    2015-01-01

    Smoking tobacco using a waterpipe (hookah) is increasing worldwide and is remarkably common among adolescents and young adults in the United States. Contrary to misperceptions that waterpipe tobacco smoking presents fewer health risks than cigarette smoking, recent data demonstrate clearly that the smoke from a waterpipe contains many of the same toxicants that are in cigarettes, including the dependence-producing drug nicotine, cancer-causing polycyclic aromatic hydrocarbons, pulmonary disease–causing volatile aldehydes, and cardiovascular disease–causing carbon monoxide that can also lead to acute intoxication in waterpipe users. Because many anesthesia providers are likely treating waterpipe tobacco smokers, the goal of this AANA Journal Course is to describe a waterpipe, who uses a waterpipe to smoke tobacco, and the toxicants found in waterpipe smoke and waterpipe smokers. Based on available evidence, there is no indication that waterpipe tobacco smoking is any less risky to patient health than cigarette smoking. Anesthesia providers should begin to assess patients for this form of tobacco use explicitly and should consider addressing it as they do cigarette smoking, with the additional precaution of presurgery carboxyhemoglobin measurement.

    Background There has been an increase in non-daily smoking, alternative tobacco product and marijuana use among young adults in recent years. Objectives This study examined perceptions of health risks, addictiveness, and social acceptability of cigarettes, cigar products, smokeless tobacco, hookah, electronic cigarettes, and marijuana among young adults and correlates of such perceptions. Methods In Spring 2013, 10,000 students at two universities in the Southeastern United States were recruited to complete an online survey (2,002 respondents), assessing personal, parental, and peer use of each product; and perceptions of health risks, addictiveness, and social acceptability of each of these products. Results Marijuana was the most commonly used product in the past month (19.2%), with hookah being the second most commonly used (16.4%). The least commonly used were smokeless tobacco products (2.6%) and electronic cigarettes (4.5%). There were high rates of concurrent product use, particularly among electronic cigarette users. The most positively perceived was marijuana, with hookah and electronic cigarettes being second. While tobacco use and related social factors, related positively, influenced perceptions of marijuana, marijuana use and related social factors were not associated with perceptions of any tobacco product. Conclusions/Importance Marketing efforts to promote electronic cigarettes and hookah to be safe and socially acceptable seem to be effective, while policy changes seem to be altering perceptions of marijuana and related social norms. Research is needed to document the health risks and addictive nature of emerging tobacco products and marijuana and evaluate efforts to communicate such risks to youth. PMID:25268294

    Objectives Hookah tobacco smoking has grown steadily in popularity among young adults in the United States. Little attention has been given to the relationship between hookah smoking and another behavior that is common among young adults – alcohol use. The purpose of this study was to examine hookah and alcohol use among young adults. Methods Forty young adult hookah smokers (55% female) participated in focus group sessions on hookah use beliefs and a brief survey examining hookah and alcohol use including drinking alcohol before, during, or after smoking hookah. Results Quotes from the focus groups indicated that alcohol use may promote hookah use among individuals who have little or no hookah smoking experience. Alcohol use, binge drinking, and alcohol use before, during, and after hookah use were common among the participants regardless of legal drinking age status. Nearly half of the participants preferred to drink alcohol while smoking hookah due to the improved physical and social effects they associated with combining the 2 behaviors. Conclusions For some young adult hookah smokers, alcohol appears to enhance the hookah smoking experience and may play a role in hookah smoking initiation. Future research and interventions should address the association between hookah and alcohol use. PMID:26248176

    Objectives (1) To confirm the prevalence of hookah use among US college students. (2) To identify substances commonly smoked in hookahs and other substance use characteristics of hookah smokers. (3) Given the powerful influence of Facebook and its potential role in promoting behaviours, to assess the prevalence of hookah references on Facebook profiles. Design Cross-sectional study. Setting Two large US universities; www.Facebook.com. Participants 307 Facebook profiles were coded and 216 of these profile owners completed an online survey. On average, participants were 18.8 years old (SD=0.7), women (54%), Caucasian (70.4%) and approximately half were from each university. Outcome measures Lifetime and frequency of hookah use, substance smoked in hookah, cigarette and marijuana use, hookah references displayed on Facebook. Results 27.8% of participants endorsed hookah use; there were no significant differences between age, gender, race or university for hookah use. Hookah users reported smoking tobacco (78%), hash (12%) and both tobacco and marijuana/hash (10%) in their hookah. Compared with non-hookah smokers, hookah smokers were more likely to report using cigarettes (OR=3.41, 95%CI=1.2 to 9.64) and marijuana (OR=15.01, 95%CI=6.5 to 34.65). Hookah references were present on 5% of Facebook profiles. Conclusions More than one quarter of college students smoke hookah. Most smoke tobacco in their hookah, and hookah smoking is associated with polysubstance use. Hookah may present new risks for nicotine addiction in this population. PMID:23242241

    Hookah (waterpipe) smoking is a very common practice that has spread globally. There is growing evidence on the hazardous consequences of smoking hookah, with studies indicating that its harmful effects are comparable to cigarette smoking if not worse. Charcoal is commonly used as a heating source for hookah smoke. Although charcoal briquettes are thought to be one of the major contributors to toxicity, their composition and impact on the smoke generated remains largely unidentified. This study aims to analyze the elemental composition of five different raw synthetic and natural charcoals by using Carbon-Hydrogen-Nitrogen (CHN) analysis, inductively coupled plasma (ICP), and scanning electron microscopy coupled with energy dispersive X-Ray spectrometry (SEM-EDS). Elemental analysis showed that the raw charcoals contain heavy metals such as zinc, iron, cadmium, vanadium, aluminum, lead, chromium, manganese and cobalt at concentrations similar, if not higher than, cigarettes. In addition, thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) was used to analyze the chemical composition of the smoke produced from burning the charcoal samples. The smoke emitted from charcoal was found to be the source of numerous compounds which could be hazardous to health. A total of seven carcinogens, 39 central nervous system depressants and 31 respiratory irritants were identified.

    Hookah tobacco smoking (HTS) has been increasing, particularly among young adults and has similar health effects compared to cigarette smoking. The link between HTS and poly-tobacco use is well documented, but fewer show an association between HTS and alcohol use. It is essential to identify factors that increase the risk for or addictiveness and consequences of HTS, given its growing prevalence. This study examined whether the association between HTS and poly-tobacco use differed as a function of age and alcohol consumption within in a sample of 1223 adult cigarette smokers. Approximately 20% of participants reported HTS. Compared to non-users, hookah users were more likely to be male, highly educated, and to report drug and alcohol use, binge drinking, and poly-tobacco use but were less likely to be heavy smokers (≥10 cigarettes per day). Regression analyses predicting number of tobacco products used (excluding cigarettes and HTS) indicated a three-way interaction of HTS, frequency of alcohol use, and age such that the association between HTS and number of tobacco products used was strongest for younger respondents who consumed alcohol more frequently. As observed in previous studies, alcohol is an important risk factor in the relationship between HTS and poly-tobacco use, particularly among younger cigarette smokers. The links between alcohol, HTS, and poly-tobacco use should be considered when developing HTS education and prevention materials directed toward younger cigarette smokers. Findings provide information relevant to FDA's interest in the addiction potential of HTS and its link to poly-tobacco use.

    The cells of buccal epithelium were investigated in groups of smoking and non-smoking students. Cell samples were collected by scraping with blunt sterile spatula, stained with orcein and photographed. The smoking of cigarettes and hookah induces significant decrease in nuclear and cell perimeter and cell area in cells of buccal epithelium. Smoking of hookah induces, besides, the heterochromatization in cell nuclei and the decrease of nuclear area. The data obtained indicate stress reaction in cells (heterochromatinization) and apoptosis-related changes in cells (decrease of nuclear and cell perimeter and cell area). These data show unfavorable effects of smoking cigarettes and even more harmful effect of hookah smoking.

    Hookah tobacco smoking (HTS) is prevalent, widespread, and associated with large amounts of toxicants. HTS may be viewed differently by males and females. For example, females have been drawn to types of tobacco which were flavored, milder, and marketed as more social and exotic. Individuals often use the growing segment of “anonymous” social networking sites, such as Tumblr, to learn about potentially dangerous or harmful behaviors. We used a systematic process involving stratification by time of day, day of week, and search term to gather a sample of 140 Tumblr posts related to HTS. After a structured codebook development process, two coders independently assessed all posts in their entirety, and all disagreements were easily adjudicated. When data on poster sex and age were available, 77% were posted by females and 35% were posted by individuals less than 18. The most prominent features displayed in all posts were references to or images of hookahs themselves, sexuality, socializing, alcohol, hookah smoke, and “tricks” performed with hookah smoke. Compared with females, males more frequently posted images of hookahs and alcohol-related images or references. This information may help guide future research in this area and development of targeted interventions to curb this behavior. PMID:26890733

    Background Exposure to smoking or passive smoking is one of serious health problems especially in the pediatric age group. Objectives To compare the prevalence and determinants of passive smoking in a nationally representative sample of Iranian children and adolescents according to their socioeconomic status (SES). Materials and Methods This nationwide study was conducted in 2011 - 2012 among 14880 students aged 6 - 18 years, living in 30 provinces in Iran. Exposure to the smoke of hookah or cigarette was documented by using validated questionnaires. Possible influencing factors were determined and the frequency of passive smoking was compared according to the regional and familial SES. Results Participants consisted of 13,486 children and adolescents including 49.2% girls and 75.6% urban inhabitants (90.6% participation rate). The mean age of participants was 12.47 ± 3.36 years. Overall, 43.87% of them (44.07% of boys and 43.66% of girls) were exposed to second hand smoke at home. Exposures to hookah or cigarette smoke at home were respectively reported in 21.46% and 34.49% of participants. The prevalence of passive smoking was lower in children of families with higher SES level, but higher in high SES regions of the country than in low SES ones, and ranged from 39.2% in the region with lowest SES to 49.05% in the highest SES region. Higher education levels of fathers and mothers were significantly associated with lower frequency of passive smoking. Conclusions Exposure to second hand smoke is a major problem among Iranian children and adolescents. Low family SES and low parental education increased the frequency of passive smoking. Appropriate public health education and legislation for smoke free home as well as family-centered counseling should be strengthened. PMID:27781078

    Objective YouTube is now the second most visited site on the Internet. We aimed to compare characteristics of and messages conveyed by cigarette- and hookah-related videos on YouTube. Methods Systematic search procedures yielded 66 cigarette-related and 61 hookah-related videos. After 3 trained qualitative researchers used an iterative approach to develop and refine definitions for the coding of variables, 2 of them independently coded each video for content including positive and negative associations with smoking and major content type. Results Median view counts were 606,884 for cigarettes and 102,307 for hookahs (P<.001). However, the number of comments per 1,000 views was significantly lower for cigarette-related videos than for hookah-related videos (1.6 vs 2.5, P=.003). There was no significant difference in the number of “like” designations per 100 reactions (91 vs. 87, P=.39). Cigarette-related videos were less likely than hookah-related videos to portray tobacco use in a positive light (24% vs. 92%, P<.001). In addition, cigarette-related videos were more likely to be of high production quality (42% vs. 5%, P<.001), to mention short-term consequences (50% vs. 18%, P<.001) and long-term consequences (44% vs. 2%, P<.001) of tobacco use, to contain explicit antismoking messages (39% vs. 0%, P<.001), and to provide specific information on how to quit tobacco use (21% vs. 0%, P<.001). Conclusions Although Internet user–generated videos related to cigarette smoking often acknowledge harmful consequences and provide explicit antismoking messages, hookah-related videos do not. It may be valuable for public health programs to correct common misconceptions regarding hookah use. PMID:22363069

    2014-01-01

    Background Waterpipe tobacco smoking has spread worldwide. However, the evaluation of scientific output in the field of waterpipe tobacco smoking has not been studied yet. The main objectives of this study were to analyze worldwide research output in the waterpipe tobacco smoking field, and to examine the authorship pattern and the citations retrieved from the Scopus database for over a decade. Methods Data from January 1, 2003 through December 31, 2012 were searched for documents with specific words regarding waterpipe tobacco smoking as “keywords” in the title. Scientific output was evaluated based on a methodology developed and used in other bibliometric studies: (a) total and trends of contributions in waterpipe tobacco smoking research between 2003 and 2012; (b) authorship patterns and research productivity; (c) collaboration patterns; (d) the citations received by the publications; and (e) areas of interest of the published papers. Results Worldwide there were 334 publications that met the criteria during the study period. The largest number of publications in waterpipe tobacco smoking were from the United States of America (USA) (33.5%), followed by Lebanon (15.3%), and France (10.5%). The total number of citations at the time of data analysis (October 18, 2013) was 4,352, with an average of 13 citations per document and a median (interquartile range) of 4.0 (1.0–16.0). The h-index of the retrieved documents was 34. The highest h-index by country was 27 for the USA, followed by 20 for Syrian Arab Republic and Lebanon. Conclusions The present data reveal a promising rise and a good start for research activity in the field of waterpipe tobacco smoking. More effort is needed to bridge the gap in waterpipe smoking-based research and to promote better evaluation of waterpipe smoking, risks, health effects, or control services worldwide. PMID:24725483

    Introduction Hookah use has gained recent popularity among U.S. youth. The current study describes the characteristics and correlates associated with hookah use in late adolescent and young adult US Air Force (USAF) recruits. Methods Data were obtained from a cross-sectional questionnaire of USAF personnel in Technical Training School at Joint Base San Antonio (N=10,997). Response rate was 78%. Logistic regression was used to analyze the associations between hookah use, demographic variables, other tobacco and nicotine containing product (TNCP) use, and the social environment. Results The prevalence of ever hookah use was 28%; at least monthly hookah use was 10%. Increased hookah use was positively associated with Hispanic ethnicity (OR [odds ratio] 1.52; 95% CI: 1.25, 1.85), cigarette smoking (OR 4.05; CI: 3.41, 4.82) and smokeless tobacco use (OR 1.35; 95% CI: 1.07, 1.71). Hookah use was negatively associated with age (OR 0.84; 95% 0.71 to 1.00), living as married (OR 0.54; 95% CI: 0.40-0.72), African American (OR 0.53; 95% CI: 0.40, 0.69) and ≥ 4-year degree (OR 0.54; 95% CI: 0.35, 0.82). Hookah use was highest among recruits who “many or almost all” of their friends smoked cigarettes (OR 2.43; 95% CI: 1.80, 3.30) and for those who reported willingness to try a tobacco product that claims to be safer than cigarettes (OR 3.16; 95% CI: 2.64, 3.77). Conclusions Hookah use among military recruits is similar to the civilian population. A willingness to try TNCPs claiming to be safer than cigarettes may influence hookah use. Public health campaigns disseminating accurate information about hookah health risks may be needed to reduce hookah use among youth. PMID:25841088

    Public policies to stop or reduce cigarette smoking and exposure to secondhand smoke and associated diseases have yielded successful results over the past decade. Yet, the growing worldwide popularity of another form of tobacco consumption, water pipe smoking, has received relatively less attention. To the best of our knowledge, no study to date has evaluated the effects of water pipe smoking on cytochrome P450 (CYP450) activities and drug interaction potential in humans, whereas only limited information is available on the impact of secondhand smoke on drug metabolism. In a sample of 99 healthy volunteers (28 water pipe smokers, 30 secondhand tobacco smoke exposed persons, and 41 controls), we systematically compared CYP1A2 and CYP2A6 enzyme activities in vivo using caffeine urine test. The median self-reported duration of water pipe smoking was 7.5 h/week and 3 years of exposure in total. The secondhand smoke group had a median of 14 h of self-reported weekly exposure to tobacco smoke indoor where a minimum of five cigarettes were smoked/hour for a total of 3.5 years (median). Analysis of variance did not find a significant difference in CYP1A2 and CYP2A6 activities among the three study groups (p > 0.05). Nor was there a significant association between the extent of water pipe or secondhand smoke exposure and the CYP1A2 and CYP2A6 activities (p > 0.05). Further analysis in a subsample with smoke exposure more than the median values also did not reveal a significant difference from the controls. Although we do not rule out an appreciable possible impact of water pipe smoke and secondhand smoke on in vivo activities of these two drug metabolism pathways, variability in smoke constituents from different tobacco consumption methods (e.g., water pipe) might affect drug metabolism in ways that might differ from that of cigarette smoke. Further studies in larger prospective samples are recommended to evaluate water pipe and secondhand tobacco smoke effects

    Popularity of waterpipe smoking or hookah smoking in the United States has been growing for some time now among youth and young adults. Currently, many cities and states have exemptions that allow hookah bars to remain in operation despite the passage of clean indoor air legislation. From a public health perspective this is concerning for many reasons. One public health concern with the increase in popularity of this type of tobacco use is the associated health effects. Another concern is that hookah smoke produces a sweet smelling aroma making it less obvious that patrons and employees of hookah bars are inhaling noxious fumes from mainstream smoke, as well as the toxins from the charcoal that is used to heat the tobacco. The purpose of this paper is to discuss smoke-free air legislation in relation to hookah use, the public health implications of exempting hookah bars from current smoke-free legislation, and implications for the public health nurse in protecting the public from the dangers of second-hand smoke, and limiting this new form of tobacco use.

    Introduction: Heating rather than burning tobacco reduces levels of harmful and potentially harmful constituents, and consumer products using this approach aim to reduce exposure to tobacco toxicants. The Tobacco Heating System (THS) version 2.1 has been enhanced from earlier prototypes with an improved heat control and sensorial experience and thereby user acceptance. Exposure measurements are required to determine whether it may be possible to reduce the individual health risk compared to smoking combustible cigarettes (CCs). Methods: This controlled clinical study randomly assigned 40 smokers to either a group continuing to use of their own CC brand (n = 20) or a group switching to THS 2.1 (n = 20) for 5 days. Biomarkers of exposure were measured at baseline and on day 1 through day 5. Product consumption, Human Puffing Topography, the occurrence of adverse events, and an assessment of subjective effects, such as smoking satisfaction and enjoyment of respiratory tract sensations, were also determined. Results: The group of smokers who switched to THS 2.1 adapted their puffing behavior initially through longer puff duration and more puffs. During the duration of the study, total puff volume returned to baseline levels and the mean daily product consumption increased but with similar nicotine exposure compared to baseline CC use. Biomarkers of exposure to tobacco smoke toxicants which inform product risk assessment were significantly reduced with THS use compared to the CC group. THS 2.1 users experienced less reinforcing effects with THS 2.1 than with their own cigarette brand. Conclusions: THS 2.1 is a promising alternative to smoking CCs. Notwithstanding possible use adaption through consumption or puffing behavior, the exposure to harmful smoke constituents was markedly reduced with the new heated tobacco platform. Implications: Exposure markers to harmful and potentially harmful smoke constituents were lowered with the THS 2.1. Heating tobacco instead of

    Background and Purpose Hookah smoking is a growing young adult phenomenon, particularly among college students. Many users feel that it is safer than other tobacco products, although its health threats are well documented. Little is known about hookah use rates in community colleges that are attended by nearly half of all US college students. This study examined hookah use in a diverse convenience sample of students attending two southern California community colleges. Methods In fall 2011, a cross-sectional, in-classroom survey was administered to 1,207 students. A series of fully adjusted multivariate logistic regressions were conducted to explore demographic, other substance use, and attitudinal correlates of lifetime and current hookah use. Results Lifetime hookah use (56%) was higher than lifetime cigarette use (49%). Gender and personal socioeconomic status were not related to hookah use. Current use (10.8%) was associated with current use of alcohol, cigars, and cigarettes. Compared to African-Americans, Whites were 2.9 times more likely to be current users, and students who perceive hookah to be more socially acceptable were 21 times more likely to currently use. Conclusion Since hookah use rates are high, colleges should offer health education programs to inform incoming students about the health risks of hookah and cessation programs. PMID:26688673

  13. Is Smokeless Tobacco Use an Appropriate Public Health Strategy for Reducing Societal Harm from Cigarette Smoking?

    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

    This study evaluated the hypothesis that smoke from harm reduction cigarettes impedes attachment and proliferation of H9 human embryonic stem cells (hESCs). Smoke from three harm reduction brands was compared with smoke from a conventional brand. Doses of smoke were measured in puff equivalents (PE) (1 PE = the amount of smoke in one puff that dissolves in 1 ml of medium). Cytotoxic doses were determined using morphological criteria and trypan blue staining, and apoptosis was confirmed using Magic Red staining. Attachment and proliferation of hESC were followed at a noncytotoxic dose in time-lapse videos collected using BioStation technology. Data were mined from videos either manually or using video bioinformatics subroutines developed with CL-Quant software. Mainstream (MS) and sidestream (SS) smoke from conventional and harm reduction cigarettes induced apoptosis in hESC colonies at 1 PE. At 0.1 PE (noncytotoxic), SS smoke from all brands inhibited attachment of hESC colonies to Matrigel with the strongest inhibition occurring in harm reduction brands. At 0.1 PE, SS smoke, but not MS smoke, from all brands inhibited hESC growth, and two harm reduction brands were more potent than the conventional brand. In general, hESC appeared more sensitive to smoke than their mouse ESC counterparts. Although harm reduction cigarettes are often marketed as safer than conventional brands, our assays show that SS smoke from harm reduction cigarettes was at least as potent or in some cases more potent than smoke from a conventional brand and that SS smoke was more inhibitory than MS smoke in all assays.

    Background: In recent years, electronic cigarettes (ECs) have been heavily advertised as an alternative smoking device as well as a possible cessation method. We aimed to review all published scientific literature pertaining to ECs and to present a simple conclusion about their effects for quitting smoking and respiratory health. Methods: This was a cross-sectional study with a search of PubMed, limited to English publications upto September 2014. The total number of papers which had ECs in its title and their conclusions positive or negative regarding ECs effects were computed. The number of negative papers was subtracted from the number of positive ones to make a score. Results: Of the 149 articles, 137 (91.9%) were accessible, of which 68 did not have inclusion criteria. In the 69 remaining articles, 24 studies supported ECs and 45 considered these to be harmful. Finally, based on this evidence, the score of ECs (computed result with positive minus negative) was −21. Conclusion: Evidence to suggest that ECs may be effective and advisable for quitting smoking or a safe alternative for smoking is lacking and may instead harm the respiratory system. However, further studies are needed. PMID:28144056

    Introduction Research suggests aerosol from electronic vapor products (EVPs) has fewer harmful constituents than conventional cigarette smoke. Even so, EVPs and other nicotine-containing products are not safe to use during pregnancy. We examined perceptions among US adults regarding harm in using EVPs rather than smoking cigarettes during pregnancy. Methods Data came from the 2015 Styles Survey, an Internet panel survey of a sample of US adults aged 18 years or older (N = 4,127). Perceived harm was assessed by asking respondents whether using EVPs was less, equally, or more harmful for pregnant women than smoking cigarettes. Descriptive statistics were used to estimate perceived harm overall and by sociodemographic characteristics and tobacco-use status. Perceived harm was assessed among all adults, women of reproductive age (18–44 years, n = 820), and women of nonreproductive age (≥45 years, n = 1,398). Results Among all adults, 11.1% believed using EVPs during pregnancy was less harmful than smoking conventional cigarettes, 51.0% believed it was equally harmful, 11.6% believed it was more harmful, and 26.2% did not know. Prevalence of perception of less harm, by demographic category, was greatest among adults aged 18 to 24 years, men, non-Hispanic whites, adults with less than a high school diploma, current EVP users, and current cigarette smokers (P < .05). Prevalence of perception of less harm was greater among women of reproductive age (9.6%) than among those of nonreproductive age (7.9%) (P < .05). Conclusion US adults have varying levels of perceptions about the harms of EVP use versus cigarette smoking during pregnancy. Efforts are warranted to prevent nicotine exposure during pregnancy and to educate adults on the dangers of using any form of tobacco during pregnancy, including EVPs. PMID:28005528

    Inhaled toxic aerosols of conventional cigarette smoke may impact not only the health of smokers, but also those exposed to second-stream smoke, especially children. Thus, less harmful cigarettes (LHCs), also called potential reduced exposure products (PREPs), or modified risk tobacco products (MRTP) have been designed by tobacco manufacturers to focus on the reduction of the concentration of carcinogenic components and toxicants in tobacco. However, some studies have pointed out that the new cigarette products may be actually more harmful than the conventional ones due to variations in puffing or post-puffing behavior, different physical and chemical characteristics of inhaled toxic aerosols, and longer exposure conditions. In order to understand the toxicological impact of tobacco smoke, it is essential for scientists, engineers and manufacturers to develop experiments, clinical investigations, and predictive numerical models for tracking the intake and deposition of toxicants of both LHCs and conventional cigarettes. Furthermore, to link inhaled toxicants to lung and other diseases, it is necessary to determine the physical mechanisms and parameters that have significant impacts on droplet/vapor transport and deposition. Complex mechanisms include droplet coagulation, hygroscopic growth, condensation and evaporation, vapor formation and changes in composition. Of interest are also different puffing behavior, smoke inlet conditions, subject geometries, and mass transfer of deposited material into systemic regions. This review article is intended to serve as an overview of contributions mainly published between 2009 and 2013, focusing on the potential health risks of toxicants in cigarette smoke, progress made in different approaches of impact analyses for inhaled toxic aerosols, as well as challenges and future directions.

    Hookah tobacco smoking is associated with substantial toxicant exposures and is increasing among college students in the US. Greek (fraternity/sorority) students, especially those living in Greek housing, have high rates of risky alcohol use. The extent to which this is true for other substances, including hookah tobacco smoking, is not well known. The objective of this study is to examine associations between Greek involvement and living arrangement (non-member, non-resident member, resident member) and rates of hookah tobacco smoking, in relation to other substances, among US college students. We used national data from 82,251 student responses from the 2008–2009 administrations of the National College Health Assessment. Generalized estimating equations were utilized to determine adjusted odds ratios for substance use outcomes based on involvement and living arrangements, while adjusting for covariates and clustering of students within institutions. Among resident members, ever use was highest for marijuana (52.4%), hookah (48.5%) and cigarettes (46.6%). In multivariable models, adjusted odds were lowest for non-Greeks and highest for Greek resident members. Compared to non-Greeks, Greek resident members had nearly double the odds for current use of hookah, cigars, and marijuana, as well as two and a half times the odds for current use of smokeless tobacco and three times the odds for alcohol bingeing. Similar to other substances, hookah tobacco smoking is highest among Greek resident members, compared with both Greeks living outside Greek housing and non-Greeks. It is valuable for substance use surveillance and intervention to focus on Greek resident members. PMID:22903805

    A recent study showed an association between hookah/opium use and gastric cancer but no study has investigated the relationship with gastric precancerous lesions. We examined the association between hookah/opium and gastric precancerous lesions and subsequent gastric cancer. In a population-based cohort study, 928 randomly selected, healthy, Helicobacter pylori-infected subjects in Ardabil Province, Iran, were followed for 10 years. The association between baseline precancerous lesions and lifestyle risk factors (including hookah/opium) was analyzed using logistic regression and presented as odds ratios (ORs) and 95% confidence intervals (CIs). We also calculated hazard ratios (HRs) and 95% CIs for the associations of lifestyle risk factors and endoscopic and histological parameters with incident gastric cancers using Cox regression models. Additionally, the proportion of cancers attributable to modifiable risk factors was calculated. During 9,096 person-years of follow-up, 36 new cases of gastric cancer were observed (incidence rate: 3.96/1,000 persons-years). Opium consumption was strongly associated with baseline antral (OR: 3.2; 95% CI: 1.2-9.1) and body intestinal metaplasia (OR: 7.3; 95% CI: 2.5-21.5). Opium (HR: 3.2; 95% CI: 1.4-7.7), hookah (HR: 3.4; 95% CI: 1.7-7.1) and cigarette use (HR: 3.2; 95% CI: 1.4-7.5), as well as high salt intake, family history of gastric cancer, gastric ulcer and histological atrophic gastritis and intestinal metaplasia of body were associated with higher risk of gastric cancer. The fraction of cancers attributable jointly to high salt, low fruit intake, smoking (including hookah) and opium was 93% (95% CI: 83-98). Hookah and opium use are risk factors for gastric cancer as well as for precancerous lesions. Hookah, opium, cigarette and high salt intake are important modifiable risk factors in this high-incidence gastric cancer area.

  2. Waterpipe tobacco smoking: A new smoking epidemic among the young?

    Waterpipe (hookah, narghile) tobacco smoking (WTS) is becoming prevalent worldwide and is one of the most popular forms of tobacco use among youth. WTS prevalence has increased dramatically among youth in the United States within the past decade. Misperceived as less harmful than cigarette smoking, WTS is associated with many of the same chronic health effects such as lung cancer, chronic obstructive pulmonary disease, cardiovascular disease, bronchitis, and asthma. Much of this risk is due to the fact that a single WTS session exposes users to large volumes of smoke that contain toxic chemicals such as carbon monoxide, cancer-causing polycyclic aromatic hydrocarbons, and volatile aldehydes. Unlike cigarette smoking, WTS poses unique risks of acute negative health outcomes including carbon monoxide poisoning and the spread of communicable diseases such as herpes and tuberculosis. Because waterpipe tobacco smoke contains the addictive chemical nicotine, youth who smoke tobacco from a waterpipe may be at risk for dependence. As a result, many youth may initiate WTS and continue to use despite negative health effects. Considering many of the potential negative health effects associated with WTS affect the pulmonary system, pulmonologists and primary care providers may treat patients who are waterpipe tobacco smokers and should be aware of the risk associated with WTS. The purpose of this review is to describe a waterpipe, the prevalence and correlates of WTS, the toxicants found in waterpipe tobacco smoke, the health effects of WTS, and implications for pulmonologists and other clinicians.

    Exposure to adult smoking can have deleterious effects on children. Interventions that assist families with smoking cessation/reduction and environmental tobacco smoke (ETS) avoidance can improve child health outcomes and reduce the risk of smoking initiation. The purpose of this review was to describe the state of the science of interventions with families to promote smoke-free home environments for infants and young children, including parent smoking reduction and cessation interventions, ETS reduction, and anti-smoking socialisation interventions, using the socio-ecological framework as a guide. A systematic review of peer-reviewed articles identified from journal databases from 2000 to 2014 was undertaken. Of 921 articles identified, 28 were included in the review. Considerable heterogeneity characterised target populations, intervention types, complexity and intensity, precluding meta-analysis. Few studies used socio-ecological approaches, such as family theories or concepts. Studies in early parenthood (child age newborn to one year) tended to focus on parent smoking cessation, where studies of families with children aged 1-5 years were more likely to target household SHSe reduction. Results suggest that interventions for reduction in ETS may be more successful than for smoking cessation and relapse prevention in families of children aged less than 5 years. There is a need for a range of interventions to support families in creating a smoke free home environment that are both tailored and targeted to specific populations. Interventions that target the social and psychodynamics of the family should be considered further, particularly in reaching vulnerable populations. Consideration is also required for approaches to interventions that may further stigmatise families containing smokers. Further research is required to identify successful elements of interventions and the contexts in which they are most effective.

    Reducing the burden of physical illness among people living with severe mental illnesses (SMI) is a key priority. Smoking is strongly associated with SMIs resulting in excessive smoking related morbidity and mortality in smokers with SMI. Smoking cessation advice and assistance from mental health practitioners would assist with reducing smoking and smoking-related harms in this group. This study examined the attitudes and practices of Australian mental health practitioners towards smoking cessation and tobacco harm reduction for smokers with SMI, including adherence to the 5As (ask, assess, advise, assist and arrange follow up) of smoking cessation. We surveyed 267 Australian mental health practitioners using a cross-sectional, online survey. Most practitioners (77.5%) asked their clients about smoking and provided health education (66.7%) but fewer provided direct assistance (31.1-39.7%). Most believed that tobacco harm reduction strategies are effective for reducing smoking related risks (88.4%) and that abstinence from all nicotine should not be the only goal discussed with smokers with SMI (77.9%). Many respondents were unsure about the safety (56.9%) and efficacy (39.3%) of e-cigarettes. Practitioners trained in smoking cessation were more likely (OR: 2.9, CI: 1.5-5.9) to help their clients to stop smoking. Community mental health practitioners (OR: 0.3, CI: 0.1-0.9) and practitioners who were current smokers (OR: 0.3, CI: 0.1-0.9) were less likely to adhere to the 5As of smoking cessation intervention. The results of this study emphasize the importance and need for providing smoking cessation training to mental health practitioners especially community mental health practitioners.

    In this work, two disperser-free microextraction methods, namely, air-agitated liquid-liquid microextraction and ultrasound-assisted emulsification microextraction are compared for the determination of a number of polycyclic aromatic hydrocarbons in aqueous samples, followed by gas chromatography with flame ionization detection. The effects of various experimental parameters upon the extraction efficiencies of both methods are investigated. Under the optimal conditions, the enrichment factors and limits of detection were found to be in the ranges of 327-773 and 0.015-0.05 ng/mL for air-agitated liquid-liquid microextraction and 406-670 and 0.015-0.05 ng/mL for ultrasound-assisted emulsification microextraction, respectively. The linear dynamic ranges and extraction recoveries were obtained to be in the range of 0.05-120 ng/mL (R(2) ≥ 0.995) and 33-77% for air-agitated liquid-liquid microextraction and 0.05-110 ng/mL (R(2) ≥ 0.994) and 41-67% for ultrasound-assisted emulsification microextraction, respectively. To investigate this common view among some people that smoking hookah is healthy due to the passage of smoke through the hookah water, samples of both the hookah water and hookah smoke were analyzed.

    Background Smoking tobacco preparations in a water pipe (hookah) is widespread in many places of the world and is perceived by many as relatively safe. We investigated biomarkers of toxicant exposure with water pipe compared to cigarette smoking. Methods We conducted a cross-over study to assess daily nicotine and carcinogen exposure with water pipe and cigarette smoking in 13 people who were experienced in using both products. Results While smoking an average of 3 water pipe sessions compared to smoking 11 cigarettes per day, water pipe use was associated with a significantly lower intake of nicotine, greater exposure to carbon monoxide and a different pattern of carcinogen exposure compared to cigarette smoking, with greater exposure to benzene and high molecular weight PAHs, but less exposure to tobacco-specific nitrosamines, 1,3-butadiene and acrolein, acrylonitrile, propylene oxide, ethylene oxide, and low molecular weight PAHs. Conclusions A different pattern of carcinogen exposure might result in a different cancer risk profile between cigarette and water pipe smoking. Of particular concern is the risk of leukemia related to high levels of benzene exposure with water pipe use. Impact Smoking tobacco in water pipes has gained popularity in the United States and around the world. Many believe that water pipe smoking is not addictive and less harmful than cigarette smoking. We provide data on toxicant exposure that will help guide regulation and public education regarding water pipe health risk. PMID:23462922

    Background Despite the recognized benefits of smoking cessation, many clinicians question if a brief smoking cessation intervention can help dedicated smokers with peripheral arterial disease understand nicotine dependence and harms related to smoking. We investigated the impact and durability of a multi-modal smoking cessation intervention on patient attitudes regarding nicotine dependence and the health effects of smoking. Methods We conducted a pilot cluster randomized trial of a brief smoking cessation intervention at eight vascular surgery practices between September 1, 2014 and August 31, 2015. Compared with control sites, patients at intervention sites received protocolized brief cessation counseling, medications and referrals to a quitline. After their clinic visit and again at 3 months, participants completed a brief survey about patient attitudes regarding nicotine dependence and the health effects of smoking. Responses to questions were analyzed using Chi2 and student’s t-tests. Results All trial participants (n=156) complete the initial survey, and 75 (45%) participants completed the follow-up survey. Intervention and control patients both reported a greater than 30-pack-year history (80% vs 90%, p=0.07) and previous failed quit attempts (77% vs 78%, p=0.8). Compared to usual care, patients in the intervention group were more likely to describe hearing advice to quit from their surgeon (98% vs. 77%, p<0.001), and expressed “a lot” or “some” interest in quitting (95.4% vs 85.7%, p=0.05). Patients in the intervention group were also more likely to acknowledge their addictive behaviors, consistently scoring higher on question bank items regarding nicotine addiction (52.9 vs 48.0, p=0.006) and the negative health effects of smoking (scaled score 56.6 vs 50.6, p=0.001). When re-surveyed three months after intervention, patients in the intervention group had larger declines in nicotine dependence and health effects domains, suggesting durable impact

    Numerous epidemiological accounts suggest that waterpipe smoking (aka hookah, shisha, narghile) has become a global phenomenon, especially among youth. The alarming spread of waterpipe and accumulating evidence of its addictive and harmful effects represent a new threat in the global fight to limit tobacco-related morbidity and mortality. In response to waterpipe's alarming trends, major public health and tobacco control organisations have started or are considering systematic collection of data about waterpipe smoking to monitor its trends and assess its harmful effects in different societies. Such plans require coordination and agreement on epidemiological measurement tools that reflect the uniqueness of this tobacco use method, and at the same time allow comparison of waterpipe trends across time and place, and with other tobacco use methods. We started a decade ago our work to develop standardised measures and definitions for the assessment of waterpipe smoking in epidemiological studies. In this communication, we try to expand and update these assessment tools in light of our increased knowledge and understanding of waterpipe use patterns, its context and marketing, as well as the need for evidence-guided policies and regulations to curb its spread. We have assembled for this purpose a group of leading waterpipe researchers worldwide, and worked through an iterative process to develop the suggested instruments and definitions based on what we know currently about the waterpipe epidemic. While the suggested measures are by no means comprehensive, we hope that they can provide the building blocks for standard and comparable surveillance of waterpipe smoking globally.

  11. Lessons from the history of tobacco harm reduction: The National Cancer Institute's Smoking and Health Program and the "less hazardous cigarette".

    Scientists and public health practitioners are sharply divided today over the risks and benefits of tobacco harm-reduction strategies. At the same time, a range of novel tobacco products is being marketed with claims of reduced exposure or risk. Current scientific efforts to study tobacco products and harm reduction should be informed by past experience. During the 1960s and 1970s, there was substantial support within government and academia, as well as among voluntary health organizations, for efforts to modify tobacco products to reduce harm. This paper analyzes the former National Cancer Institute (NCI) Smoking and Health Program, which, between 1968 and 1980, pursued the development of "less hazardous" cigarettes as its primary goal. During this period, the program spent over dollar 50 million on contract research, of which 74% went toward biological and chemical analysis of modified cigarettes, 9.6% to epidemiological studies of risk factors, and only 1.4% to studies evaluating smoking cessation or prevention programs. NCI officials predicted during the mid-1970s that new "low-tar" cigarette brands would substantially reduce smoking-related mortality, but by 1978 the research agenda began to change in response to a reorganization of NCI research activities, modification of government antismoking efforts, and an emerging understanding of nicotine addiction that challenged key scientific assumptions. In retrospect, the program suffered from significant weaknesses that severely limited the likelihood that it would generate knowledge beneficial to public health, including a research agenda that failed to include surveillance and behavioral research, tobacco industry influence of the research agenda, and a lack of access to information about the characteristics of products on the market. There exists today a need for a public health-oriented research agenda on tobacco products and harm reduction, but current efforts should include input from a diverse range of

    Objective Tobacco companies have made extensive efforts to build alliances against comprehensive smoke-free legislation. This article analyses the interaction between actors who opposed the development of the European Council Recommendation on smoke-free environments. Methods Drawing on data from 200 policy documents and 32 semistructured interviews and using qualitative textual analysis and organisational network analysis, opponents’ positions on, and responses to, the policy initiative, strategies to oppose the policy, and efforts to build alliances were investigated. Results The non-binding nature of the policy, scientific evidence and clear political will to adopt EU-wide measures combined to limit the intensity of commercial sector opposition to the comprehensive EU smoke-free policy. Most tobacco companies, led by the Confederation of European Community Cigarette Manufacturers (CECCM), voiced reservations against the proposal, criticised the policy process and fought flanking measures on product regulation. However, some companies focused on instigating harm reduction debates. These divergent approaches and the reluctance of other commercial actors to demonstrate solidarity with the tobacco sector prevented the establishment of a cohesive commercial sector alliance. Conclusions The comparatively limited opposition to EU smoke-free policy contrasts with previous accounts of tobacco industry resistance to tobacco control. While context-specific factors can partially explain these differences, the paper indicates that the sector's diminished credibility and lack of unity hampered political engagement and alliance building. Industry efforts to emphasise the benefits of smokeless tobacco during smoke-free policy debates highlight the potential of harm reduction as a gateway for tobacco companies to re-enter the political arena.

    Mass media campaigns can play an important role in strengthening support for smoke-free policies and reducing exposure to secondhand smoke (SHS). Identifying anti-SHS advertisements that are effective in diverse cultural contexts may allow for resource sharing in low- and middle-income countries. A convenience sample of 481 male cigarette smokers and non-smokers in three high tobacco burden and culturally dissimilar countries (India, China and Russia) viewed and rated five anti-SHS ads. Multivariate logistic regression analyses were conducted for 'Message Acceptance', 'Negative Emotion', 'Perceived Effectiveness' and 'Behavioral Intentions'. Smokers and non-smokers in all countries consistently rated the strong graphic, health harm ads as the most effective, and the 'informational' ad as the least effective overall: the graphic ad 'Baby Alive' was at least 1.8 times more likely than the informational ad 'Smoke-free works' to receive positive ratings on all four outcomes (all P < 0.001). Graphic, health harm messages about SHS exposure have the greatest universal appeal and are the most effective in motivating changes in behavioral intentions. Similarity in reactions between smokers and non-smokers, and across countries, suggests that resource sharing and the use of a single graphic ad targeted at smokers and non-smokers would be cost-efficient strategies.

    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.

    A wide range of support is available to help smokers to quit and to aid attempts at harm reduction, including three first-line smoking cessation medications: nicotine replacement therapy, varenicline and bupropion. Despite the efficacy of these, there is a continual need to diversify the range of medications so that the needs of tobacco users are met. This paper compares the first-line smoking cessation medications with (1) two variants of these existing products: new galenic formulations of varenicline and novel nicotine delivery devices; and (2) 24 alternative products: cytisine (novel outside Central and Eastern Europe), nortriptyline, other tricyclic antidepressants, electronic cigarettes, clonidine (an anxiolytic), other anxiolytics (e.g. buspirone), selective serotonin reuptake inhibitors, supplements (e.g. St John's wort), silver acetate, Nicobrevin, modafinil, venlafaxine, monoamine oxidase inhibitors (MAOIs), opioid antagonists, nicotinic acetylcholine receptor (nAChR) antagonists, glucose tablets, selective cannabinoid type 1 receptor antagonists, nicotine vaccines, drugs that affect gamma-aminobutyric acid (GABA) transmission, drugs that affect N-methyl-D-aspartate (NMDA) receptors, dopamine agonists (e.g. levodopa), pioglitazone (Actos; OMS405), noradrenaline reuptake inhibitors and the weight management drug lorcaserin. Six 'ESCUSE' criteria-relative efficacy, relative safety, relative cost, relative use (overall impact of effective medication use), relative scope (ability to serve new groups of patients) and relative ease of use-are used. Many of these products are in the early stages of clinical trials; however, cytisine looks most promising in having established efficacy and safety with low cost. Electronic cigarettes have become very popular, appear to be efficacious and are safer than smoking, but issues of continued dependence and possible harms need to be considered.

    2015-01-01

    Background While cigarette use has seen a steady decline in recent years, hookah (water pipe) use has rapidly increased in popularity. While anecdotal reports have noted a rise in hookah bars, methodological difficulties have prevented researchers from drawing definitive conclusions about the number of hookah bars in any given location. There is no publicly available database that has been shown to reliably provide this information. It is now possible to analyze Internet trends as a measure of population behavior and health-related phenomena. Objective The objective of the study was to investigate whether Yelp can be used to accurately identify the number of hookah bars in New York State, assess the distribution and characteristics of hookah bars, and monitor temporal trends in their presence. Methods Data were obtained from Yelp that captures a variety of parameters for every business listed in their database as of October 28, 2014, that was tagged as a “hookah bar” and operating in New York State. Two algebraic models were created: one estimated the date of opening of a hookah bar based on the first Yelp review received and the other estimated whether the bar was open or closed based on the date of the most recent Yelp review. These findings were then compared with empirical data obtained by Internet searches. Results From 2014 onward, the date of the first Yelp review predicts the opening date of new hookah bars to within 1 month. Yelp data allow the estimate of such venues and demonstrate that new bars are not randomly distributed, but instead are clustered near colleges and in specific racial/ethnic neighborhoods. New York has seen substantially more new hookah bars in 2012-2014 compared with the number that existed prior to 2009. Conclusions Yelp is a powerful public health tool that allows for the investigation of various trends and characteristics of hookah bars. New York is experiencing tremendous growth in hookah bars, a worrying phenomenon that

    The damage of the human respiratory ciliated epithelium or its ciliar activity caused by mixtures of harmful substances in the air and cigarette smoke is a considerable parameter for the judgment of acute harmful influences on the human respiratory tract. As an immediate measuring or a quantitative statement about the influence on cilia in vivo at human beings is extremely difficult and problematic, a convenient model experimental system in form of the so called ciliate mobility test (CMT) has been used. In this connection the influence on cilia of the protozan single-celled organism Tetrahymena pyriformis, regarding its average speed of locomotion has been taken as standard. The proof, that the cilia are identical in morphological and functional respect at the human ciliated epithelium and at T. pyriformis has been reached by electron optical comparative representation and bibliographical known substances, influencing cilia (theophylline, bromhexine, ambroxol, terpin hydrate, mercaptoethanesulfonat-sodium, amrinon, salbutamol, tetracosactid-hexaacetate, histamine, and phenol). With regard to the comparability and applicability to the human respiratory ciliated epithelium we have been able to gain statements by means of the CMT. By constructing a special reaction vessel the influence of harmful gases at a thin layer of ciliate culture suspension (1 cm) for a standardised exposure time (1 hour) has been made possible and with that a model for the comparability with the conditions of the human respiratory ciliated epithelium has been created. A number of harmful gases, that are relevant in the air hygiene (CO, CO2, N2, N2O, NO2, O3, SO2) as well as cigarette smoke at active smokers (primary stream smoke) and the inhalation of the smoke of other people's cigarettes has been tested. It turned out, that especially NO2 (nitric oxide) shows a high ciliar toxicity, while the controversially discussed ozone (O3) has not resulted in detraction of cilia. CO, N2O and SO2 have

    of combustible cigarettes and e-cigarettes, and the Stopsmoking subreddit focused on psychological aspects of quitting. Last, we examined the discussion content on Vapor Talk and Hookah Forum. Prominent topics included equipment, technique, experiential elements of use, and the buying and selling of equipment. Conclusions This study has three main contributions. Discussion forums differ in the extent to which their content may help us understand behaviors with potential health implications. Identifying dimensions of interest and using a heat map visualization to compare across forums can be helpful for identifying forums with the greatest density of health information. Additionally, our work has shown that the quitting experience can potentially be very different depending on whether or not e-cigarettes are used. Finally, e-cigarette and hookah forums are similar in that members represent a “hobbyist culture” that actively engages in information exchange. These differences have important implications for both tobacco regulation and smoking cessation intervention design. PMID:26420469

    Since the introduction of e-cigarettes into the U.S. market, the number and variety of vaping products have proliferated. E-hookahs are long, pen-like vaping devices that debuted in U.S. markets in 2014. By applying the Host, Agent, Vector, Environment (HAVE) model, the objective of this exploratory study was to assess differences between e-cigarettes and e-hookahs to help inform tobacco regulatory science and practice. In June–August 2014, a total of 54 unique manufactured e-cigarette and e-hookah products were identified at point of sales (POS) around three college campuses in Southeast U.S. Documented characteristics included brand name, disposable, rechargeable, nicotine containing, packaging, and flavor type. Descriptive analyses were conducted October to November 2014 to assess frequency and percent of product type across POS and specific characteristics. Among 54 products, 70.4% was e-cigarettes and 29.6% was e-hookahs. Across POS, drug stores and grocery stores carried e-cigarettes exclusively, while gas stations carried the greatest proportion of e-hookahs. Compared to e-hookahs, a greater proportion of e-cigarettes were non-disposable and contained nicotine; a greater proportion of e-hookahs came in fruit and other types of flavors compared to e-cigarettes. The present study suggests that e-cigarettes and e-hookahs differ by specific product characteristics and by places where they are sold. Despite these differences, the products are used for similar purposes warranting careful monitoring of industry manufacturing and marketing, because the safety of both products is still undetermined. Additional research is needed to understand the uptake and continued use of these products. PMID:26740911

    2014-01-01

    Tobacco is a preventable cause of morbidity and mortality across the world. A recently infamous way of smoking tobacco is shisha. Shisha smoking is also known as water pipe, hookah and Narghile smoking. The percentage of shisha smokers is on the rise rapidly spanning the globe. A literature review was conducted to identify all evidence on the epidemiological variations and health effects of shisha smoking. “Pub med” is used as a searching tool to identify all relevant empirical studies conducted worldwide. A qualitative overview of evidence is presented. Exposure to Shisha smoking is significantly associated with low infant weight, heart rate variations, hyperglycemia and hypertriglyceridemia. Increased risk of carcinoma is also leagued with it including carcinomas of the pancreas and lung being at the forefront. In conclusion, this review identifies grounds of several adverse conditions being associated with the habit of shisha smoking. It also evaluates the relevant epidemiological variations around the globe. The review culminates in the importance of enlightening shisha smokers regarding its deleterious effects. PMID:24708750

    The purpose of this review is to examine the rapidly expanding literature regarding the effects of prenatal tobacco and postnatal secondhand smoke (SHS) exposure on child health and development. Mechanisms of SHS exposure are reviewed, including critical periods during which exposure to tobacco products appears to be particularly harmful to the developing fetus and child. The biological, biochemical, and neurologic effects of the small fraction of identified components of SHS are described. Research describing these adverse effects of both in utero and childhood exposure is reviewed, including findings from both animal models and humans. The following adverse physical outcomes are discussed: sudden infant death syndrome, low birth weight, decreased head circumference, respiratory infections, otitis media, asthma, childhood cancer, hearing loss, dental caries, and the metabolic syndrome. In addition, the association between the following adverse cognitive and behavioral outcomes and such exposures is described: conduct disorder, attention-deficit/hyperactivity disorder, poor academic achievement, and cognitive impairment. The evidence supporting the adverse effects of SHS exposure is extensive yet rapidly expanding due to improving technology and increased awareness of this profound public health problem. The growing use of alternative tobacco products, such as hookahs (a.k.a. waterpipes), and the scant literature on possible effects from prenatal and secondhand smoke exposure from these products are also discussed. A review of the current knowledge of this important subject has implications for future research as well as public policy and clinical practice.

    Objective: To conduct a comprehensive review regarding global waterpipe use, in order to identify current knowledge, guide scientific research, and promote public policy. Data sources: A Medline search using as keywords "waterpipe", "narghile", "arghile", "shisha", "hookah", "goza", "hubble bubble" and variant spellings (for example, "hooka"; "hukka") was conducted. Resources compiled recently by members of GLOBALink were used. Study selection: Every identified published study related to waterpipe use was included. Data synthesis: Research regarding waterpipe epidemiology and health effects is limited; no published studies address treatment efforts. Waterpipe use is increasing globally, particularly in the Eastern Mediterranean Region, where perceptions regarding health effects and traditional values may facilitate use among women and children. Waterpipe smoke contains harmful constituents and there is preliminary evidence linking waterpipe smoking to a variety of life threatening conditions, including pulmonary disease, coronary heart disease, and pregnancy related complications. Conclusions: More scientific documentation and careful analysis is required before the spread of waterpipe use and its health effects can be understood, and empirically guided treatment and public policy strategies can be implemented.

    Objectives In the past decade, waterpipe smoking (a.k.a. hookah, shisha, narghile) has become a global phenomenon. In this review, we provide an updated picture of the main epidemiological trends in waterpipe smoking globally. Data sources Peer-reviewed publications indexed in major biomedical databases between 2004 and 2014. Search keywords included a combination of: waterpipe, hookah, shisha along with epidemiology, patterns, prevalence and predictors. We also used different spellings of waterpipe terms commonly used. Study selection The focus was on studies with large representative samples, national data or high-quality reports that illuminated aspects of the epidemiology and trends in waterpipe smoking. Data extraction Multiple researchers extracted the data independently and collectively decided on the most important and pertinent studies to include in the review. Data synthesis Waterpipe smoking has become a global phenomenon among youth. The global waterpipe epidemic is likely driven by (1) the introduction of manufactured flavoured tobacco (Maassel); (2) the intersection between waterpipe's social dimension and thriving café culture; (3) the evolution of mass communication media; (4) the lack of regulatory/policy framework specific to the waterpipe. Waterpipe smoking is becoming the most popular tobacco use method among youth in the Middle East, and is quickly gaining popularity elsewhere. Important patterns of waterpipe smoking include the predominance among younger, male, high socioeconomic, and urban groups. Intermittent and social use are also noted patterns. Conclusions Waterpipe smoking has become a global public health problem. Developing surveillance, intervention and regulatory/policy frameworks specific to the waterpipe has become a public health priority. PMID:25298368

    In recent years, youth have been exposed to a broader spectrum of tobacco products including smokeless tobacco, hookah (water pipe) and e-cigarettes. Despite active local, provincial/territorial and national prevention strategies and legislated controls, thousands of teenagers develop an addiction to tobacco products each year. Current and available smoking cessation interventions for youth have the potential to help teens stop smoking and, as a result, greatly reduce Canada’s health burden in the future. Paediatricians and health care professionals can play a key role in helping teens make informed decisions related to tobacco consumption and cessation. This practice point presents the evidence and rationales for smoking cessation interventions which have been studied in youth specifically, such as individual counselling, psychological support, nicotine replacement therapy, bupropion and varenicline. Interventions for which limited or conflicting data exist are also discussed. PMID:27429574

    2016-01-01

    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 There is no safe level of exposure to tobacco smoke. Thirdhand smoke is residual tobacco smoke contamination that remains after the cigarette is extinguished. Children are uniquely susceptible to thirdhand smoke exposure. The objective of this study was to assess health beliefs of adults regarding thirdhand smoke exposure of children and whether smokers and nonsmokers differ in those beliefs. We hypothesized that beliefs about thirdhand smoke would be associated with household smoking bans. METHODS Data were collected by a national random-digit-dial telephone survey from September to November 2005. The sample was weighted by race and gender within Census region on the basis of US Census data. The study questions assessed the level of agreement with statements that breathing air in a room today where people smoked yesterday can harm the health of children. RESULTS Of 2000 eligible respondents contacted, 1510 (87%) completed surveys, 1478 (97.9%) answered all questions pertinent to this analysis, and 273 (18.9%) were smokers. Overall, 95.4% of nonsmokers versus 84.1% of smokers agreed that secondhand smoke harms the health of children, and 65.2% of nonsmokers versus 43.3% of smokers agreed that thirdhand smoke harms children. Strict rules prohibiting smoking in the home were more prevalent among nonsmokers: 88.4% vs 26.7%. In multivariate logistic regression, after controlling for certain variables, belief that thirdhand smoke harms the health of children remained independently associated with rules prohibiting smoking in the home. Belief that secondhand smoke harms the health of children was not independently associated with rules prohibiting smoking in the home and car. CONCLUSIONS This study demonstrates that beliefs about the health effects of thirdhand smoke are independently associated with home smoking bans. Emphasizing that thirdhand smoke harms the health of children may be an important element in encouraging home smoking bans. PMID:19117850

    The author presents data on the biological casualties and consequences of tobacco-smoking. Smoking is the most dangerous addiction in the scale of the world and in Poland. It causes numerous premature decrease and tobacco-dependent sickness. The author characterises the spread of this addiction in Poland concentrating on the problem of the passive smoking harmfulness. Non-smokers, children and youth, embryo and foetus during the pregnancy are exposed to the passive smoking. The experimental examinations of animals and the analysis of the lateral stream of the tobacco smoke confirm not the least, but rather the greater damage of the passive smoking than the active one. The mechanisms of acting of the tobacco smoke on the passive smokers' body and the health consequences are discussed. The manners, means and activities that are useful for the health protection of non-smokers against the tobacco smoke and the ways of the smoking prevention are described.

    Objectives. We evaluated changing patterns of tobacco use following a period of forced tobacco abstinence in a US military cohort to determine rates of harm elimination (e.g., tobacco cessation), harm reduction (e.g., from smoking to smokeless tobacco use), and harm escalation (e.g., from smoking to dual use or from smokeless tobacco use to smoking or dual use). Methods. Participants were 5225 Air Force airmen assigned to the health education control condition in a smoking cessation and prevention trial. Tobacco use was assessed by self-report at baseline and 12 months. Results. Among 114 baseline smokers initiating smokeless tobacco use after basic military training, most demonstrated harm escalation (87%), which was 5.4 times more likely to occur than was harm reduction (e.g., smoking to smokeless tobacco use). Harm reduction was predicted, in part, by higher family income and belief that switching from cigarettes to smokeless tobacco is beneficial to health. Harm escalation predictors included younger age, alcohol use, longer smoking history, and risk-taking. Conclusions. When considering a harm reduction strategy with smokeless tobacco, the tobacco control community should balance anticipated benefits of harm reduction with the risk of harm escalation and the potential for adversely affecting public health.

    Waterpipe (WP) use has surged in popularity since the introduction of flavoured shisha. It is now an increasingly popular form of smoking among youth in North America. Health professionals/educators knowledge about the WP may well be inadequate. This study, using qualitative methods, sought to explore the knowledge and attitude of leaders in the community toward the WP. Family physicians, pharmacists, tobacco counsellors, social workers and educators were invited to participate in a one-one interview using open-ended questions. A total of 27 interviews were conducted. Individuals from Eastern Mediterranean backgrounds raised doubt about the overemphasised cultural significance of the WP and perceived this as a marketing strategy by industry. Most felt that WP smokers believed the WP to be less harmful than cigarettes and that the use of flavoured tobacco was motivating people to smoke. Participants believed that education should be directed at the general public and healthcare professionals, suggesting school programs and the use of social media to inform young smokers. Most thought that the current practices regarding packaging and second hand smoke exposure are confusing. They identified the lack of knowledge, poor enforcement procedures, "so called cultural aspects" and the economic impact of banning the WP on small businesses as barriers to change. Despite the awareness of an increase in WP use, our participants recognized that little has been done to curb this problem. Our findings emphasize the need for further education and better legislation to regulate WP use and availability.

    Background Secondhand smoke, which is also referred to as environmental tobacco smoke and passive smoke, is a known human carcinogen. Secondhand smoke also causes disease and premature death in nonsmoking adults and children. Methods We summarize studies of secondhand smoke in public places before and after smoking bans, as well as studies of cardiovascular and respiratory disease before and after such bans. Results To protect the public from the harmful effects of secondhand smoke, smoke-free legislation is an effective public health measure. Smoking bans in public places, which have been implemented in many jurisdictions across the U.S. and in other countries, have the potential to influence social norms and reduce smoking behavior. Conclusions Through legislative smoking bans for reducing secondhand smoke exposure and smoking prevalence, opportunities exist to protect the health of Georgians and other Americans and to reduce health care costs. These opportunities include increasing the comprehensiveness of smoking bans in public places and ensuring adequate funding to quit line services. PMID:26345719

    The medical consultation during pregnancy should include information about smoking and side-stream smoking. More than half of the fetuses are more or less exposed to harmful substances passing the placenta due to smoking of the mother or smoking persons in the direct environment. The danger due to side-stream smoking have to be considered more during the consultation. It is known that toxic substances are concentrated higher in the side-stream smoke than in the main-stream smoke. Due to enzyme induction, smokers can metabolize toxic substances faster than non-smokers or side-stream smokers. Already before a planned pregnancy, it should be pointed out that tobacco smoke contains numerous teratogenic substances which double the risk of fetal malformations. A high consumption of cigarettes induces an increased risk of abortion. An insufficient perfusion of the uterus and the placenta causes an O2-debt with an increased risk for malformations such as schistasis or an increased rate of premature birth. The increased CO content of the maternal blood reduces the O2 transport capacity since CO has an about 200 times greater affinity to hemoglobin than O2. These and other topics of the consultation for pregnant women are important in the interest of the fetus.

    Objective There has been a rapid increase in the use of waterpipe tobacco and non-tobacco based shisha in many countries. Understanding the impact and effects of second-hand smoke (SHS) from cigarette was a crucial factor in reducing cigarette use, leading to clean indoor air laws and smoking bans. This article reviews what is known about the effects of SHS exposure from waterpipes. Data sources We used PubMed and EMBASE to review the literature. Articles were grouped into quantitative measures of air quality and biological markers, health effects, exposure across different settings, different types of shisha and use in different countries. Study selection Criteria for study selection were based on the key words related to SHS: waterpipe, hookah, shisha and third-hand smoke. Data extraction Independent extraction with two reviewers was performed with inclusion criteria applied to articles on SHS and waterpipe/hookah/shisha. We excluded articles related to pregnancy or prenatal exposure to SHS, animal studies, and non-specific source of exposure as well as articles not written in English. Data synthesis A primary literature search yielded 54 articles, of which only 11 were included based on relevance to SHS from a waterpipe/hookah/shisha. Conclusions The negative health consequences of second-hand waterpipe exposure have major implications for clean indoor air laws and for occupational safety. There exists an urgent need for public health campaigns about the effects on children and household members from smoking waterpipe at home, and for further development and implementation of regulations to protect the health of the public from this rapidly emerging threat.

    The lack of scientific evidence on the constituents, properties, and health effects of second-hand waterpipe smoke has fueled controversy over whether public smoking bans should include the waterpipe. The purpose of this study was to investigate and compare emissions of ultrafine particles (UFP, <100 nm), carcinogenic polyaromatic hydrocarbons (PAH), volatile aldehydes, and carbon monoxide (CO) for cigarettes and narghile (shisha, hookah) waterpipes. These smoke constituents are associated with a variety of cancers, and heart and pulmonary diseases, and span the volatility range found in tobacco smoke. Sidestream cigarette and waterpipe smoke was captured and aged in a 1 m 3 Teflon-coated chamber operating at 1.5 air changes per hour (ACH). The chamber was characterized for particle mass and number surface deposition rates. UFP and CO concentrations were measured online using a fast particle spectrometer (TSI 3090 Engine Exhaust Particle Sizer), and an indoor air quality monitor. Particulate PAH and gaseous volatile aldehydes were captured on glass fiber filters and DNPH-coated SPE cartridges, respectively, and analyzed off-line using GC-MS and HPLC-MS. PAH compounds quantified were the 5- and 6-ring compounds of the EPA priority list. Measured aldehydes consisted of formaldehyde, acetaldehyde, acrolein, methacrolein, and propionaldehyde. We found that a single waterpipe use session emits in the sidestream smoke approximately four times the carcinogenic PAH, four times the volatile aldehydes, and 30 times the CO of a single cigarette. Accounting for exhaled mainstream smoke, and given a habitual smoker smoking rate of 2 cigarettes per hour, during a typical one-hour waterpipe use session a waterpipe smoker likely generates ambient carcinogens and toxicants equivalent to 2-10 cigarette smokers, depending on the compound in question. There is therefore good reason to include waterpipe tobacco smoking in public smoking bans.

    Purpose This study aimed to assess the rate of tobacco consumption among professional athletes in Iran and assessing their knowledge and attitude in this regard. Methods A total of 738 athletes from 10 different types of sports were evaluated. Athletes were all members of the priority leagues. After obtaining consent from the Physical Education Organization and coordination with the related federations, athletes were asked to fill out the standard questionnaire. Results All understudy subjects were males. The mean age was 28.4±2.7 yrs. The mean age of initiation of sport in these subjects was reported to be 12.3±4.01 yrs. A total of 178 (24.6%) subjects had experienced cigarette smoking and 308 (42.3%) had experienced hookah smoking. Sixty four subjects (9%) were current smokers. The mean score of knowledge about hazards of smoking was 5.6±0.9 among those who had experienced smoking. This score was 7.9±0.5 among those with no smoking experience (P=0.04). Conclusions Rate of smoking among professional athletes is lower than general population average. So participation in organized sports may be a protective factor against tobacco use in people.

  11. Self-harm.

    PubMed

    Skegg, Keren

    The term self-harm is commonly used to describe a wide range of behaviours and intentions including attempted hanging, impulsive self-poisoning, and superficial cutting in response to intolerable tension. As with suicide, rates of self-harm vary greatly between countries. 5-9% of adolescents in western countries report having self-harmed within the previous year. Risk factors include socioeconomic disadvantage, and psychiatric illness--particularly depression, substance abuse, and anxiety disorders. Cultural aspects of some societies may protect against suicide and self-harm and explain some of the international variation in rates of these events. Risk of repetition of self-harm and of later suicide is high. More than 5% of people who have been seen at a hospital after self-harm will have committed suicide within 9 years. Assessment after self-harm includes careful consideration of the patient's intent and beliefs about the lethality of the method used. Strong suicidal intent, high lethality, precautions against being discovered, and psychiatric illness are indicators of high suicide risk. Management after self-harm includes forming a trusting relationship with the patient, jointly identifying problems, ensuring support is available in a crisis, and treating psychiatric illness vigorously. Family and friends may also provide support. Large-scale studies of treatments for specific subgroups of people who self-harm might help to identify more effective treatments than are currently available. Although risk factors for self-harm are well established, aspects that protect people from engaging in self-harm need to be further explored.

    Background The global rise in tobacco smoking using a waterpipe (hookah, narghile, shisha) has made understanding its health consequences imperative. One key to developing this understanding is identifying and quantifying carcinogens and other toxicants present in waterpipe smoke. To do so, the toxicant yield of machine-generated waterpipe smoke has been measured. However, the relevance of toxicant yields of machine-generated smoke to actual human exposure has not been established. Methods In this study, we examined whether CO and nicotine yields measured using a smoking machine programmed to replicate the puffing behavior of 31 human participants who smoked a waterpipe could reliably predict these participant’s blood-level exposure. In addition to CO and nicotine, yields of PAH, volatile aldehydes, NO, and “tar” were measured. Results We found that when used in this puff-replicating manner, smoking machine yields are highly correlated with blood-level exposure (Nicotine: r>0.76, p<0.001; CO: r>0.78, p<0.001). Total drawn smoke volume was the best predictor of toxicant yield and exposure, accounting for approximately 75–100% of the variability across participants in yields of NO, CO, volatile aldehydes and “tar”, and blood-level CO and normalized nicotine. Conclusions Machine-based methods can be devised in which smoke toxicant yields reliably track human exposure. Impact This finding indicates the basic feasibility of valid analytical laboratory evaluation of tobacco products for regulatory purposes. PMID:21914836

    Alcohol misuse can harm people other than the drinker, and can have negative consequences for society as a whole. It is commonly believed to play a role in decreased worker productivity, increased unintentional injuries, aggression and violence against others, and child and spouse abuse. Research findings support the idea that drinking is involved in or associated with many of these social harms, but do not offer evidence that it causes these effects. Methodological flaws characterize much of the research in this area. Use of better design and statistical methodology is necessary in order to clarify the relationship between drinking and the harmful consequences it is believed to cause.

    Introduction: Use of electronic nicotine delivery systems (ENDS), including electronic cigarettes (e-cigarettes), is increasing. One concern is the appeal of these products to youth and young adults and the potential to influence perceptions and use of conventional cigarettes. Methods: Using data from the 2012–2013 National Adult Tobacco Survey, characteristics of adults aged 18–29 years who had never established cigarette smoking behavior were examined by ever use of e-cigarettes, demographics, and ever use of other tobacco products (smokeless tobacco, cigars, hookah, and cigarettes). Multivariate logistic regression was used to examine the relationship between e-cigarette use and openness to cigarette smoking among young adults, defined as the lack of a firm intention not to smoke soon or in the next year. Results: Among young adults who had never established cigarette smoking behavior (unweighted n = 4,310), 7.9% reported having ever tried e-cigarettes, and 14.6% of those who reported having ever tried e-cigarettes also reported current use of the product. Ever e-cigarette use was associated with being open to cigarette smoking (adjusted odds ratio = 2.4; 95% confidence interval = 1.7, 3.3), as was being male, aged 18–24 years, less educated, and having ever used hookah or experimented with conventional cigarettes. Conclusions: Ever use of e-cigarettes and other tobacco products was associated with being open to cigarette smoking. This study does not allow us to assess the directionality of this association, so future longitudinal research is needed to illuminate tobacco use behaviors over time as well as provide additional insight on the relationship between ENDS use and conventional cigarette use among young adult populations.

    Waterpipe (also called hookah, shisha, or narghile) smoking is a common form of tobacco use in the Middle East. Its use is becoming more prevalent in Western societies, especially among young adults as an alternative form of tobacco use to traditional cigarettes. While the risk to cigarette smoking is well documented, the risk to waterpipe smoking is not well defined with limited information on its health impact at the epidemiologic, clinical and biologic levels with respect to lung disease. Based on the knowledge that airway epithelial cell DNA methylation is modified in response to cigarette smoke and in cigarette smoking-related lung diseases, we assessed the impact of light-use waterpipe smoking on DNA methylation of the small airway epithelium (SAE) and whether changes in methylation were linked to the transcriptional output of the cells. Small airway epithelium was obtained from 7 nonsmokers and 7 light-use (2.6 ± 1.7 sessions/wk) waterpipe-only smokers. Genome-wide comparison of SAE DNA methylation of waterpipe smokers to nonsmokers identified 727 probesets differentially methylated (fold-change >1.5, p<0.05) representing 673 unique genes. Dominant pathways associated with these epigenetic changes include those linked to G-protein coupled receptor signaling, aryl hydrocarbon receptor signaling and xenobiotic metabolism signaling, all of which have been associated with cigarette smoking and lung disease. Of the genes differentially methylated, 11.3% exhibited a corresponding significant (p<0.05) change in gene expression with enrichment in pathways related to regulation of mRNA translation and protein synthesis (eIF2 signaling and regulation of eIF4 and p70S6K signaling). Overall, these data demonstrate that light-use waterpipe smoking is associated with epigenetic changes and related transcriptional modifications in the SAE, the cell population demonstrating the earliest pathologic abnormalities associated with chronic cigarette smoking.

    Tobacco consumption is a major causative agent for various deadly diseases such as coronary artery disease and cancer. It is the largest avoidable health risk in the world, causing more problems than alcohol, drug use, high blood pressure, excess body weight or high cholesterol. As countries like Indonesia prepare to develop national policy guidelines for tobacco harm reduction, the scientific community can help by providing continuous ideas and a forum for sharing and distributing information, drafting guidelines, reviewing best practices, raising funds, and establishing partnerships. We propose several strategies for reducing tobacco consumption, including advertisement interference, cigarette pricing policy, adolescent smoking prevention policy, support for smoking cessation therapy, special informed consent for smokers, smoking prohibition in public spaces, career incentives, economic incentives, and advertisement incentives. We hope that these strategies would assist people to avoid starting smoking or in smoking cessation.

    The purpose of the study was to test the moderating influence of socioeconomic status (SES) on the associations between inhibitory control and the onset of combustible cigarette, electronic (e-) cigarette, and hookah use in early adolescence. A total of 407 adolescents self-reported nicotine use, inhibitory control, and SES. The hypothesis that inhibitory control would be significantly associated with nicotine use onset (i.e., combustible cigarettes, e-cigarettes, and hookah) only under the condition of low SES was tested. Direct associations were found for inhibitory control on "ever use" of all three nicotine use variables. A moderating effect was also found whereby low inhibitory control was significantly associated with nicotine use onset when participants were from low, but not high, SES families. Findings illustrate one contextual condition under which inhibitory control is associated with early onset of nicotine use.

    Objective This study explored the extent to which Malaysian and Thai smokers believe “light” and menthol cigarettes are less harmful than “regular” cigarettes and the correlates of these beliefs. Methods The study used data from wave 1 of the International Tobacco Control Southeast Asia Survey. 2006 adult smokers (95.3% male) from Malaysia and 2000 adult smokers (94.5% male) from Thailand were interviewed face to face in 2005. Results 29% of Malaysian respondents reported currently smoking light cigarettes and 14% menthols, with 19% agreeing that lights are less harmful and 16% agreeing that menthols are less harmful. 38% of Thai respondents reported currently smoking light cigarettes and 19% menthols, with 46% agreeing that lights are less harmful and 35% agreeing that menthols are less harmful. Malaysian smokers reporting current use of light or menthol cigarettes were more likely to believe that they are less harmful. Reported use of lights did not relate to beliefs for Thai respondents. The belief that light and/or menthol cigarettes are less harmful was strongly related to the belief that they have smoother smoke. Conclusions The experience of smoother smoke is likely to produce some level of belief in reduced harm, regardless of how brands are labelled and whether or not Federal Trade Commission FTC/International Organisation for Standardisation tar, nicotine and carbon monoxide yield figures are used.

  5. Harmful Algal Blooms

    Graham, Jennifer L.

    2007-01-01

    What are Harmful Algal Blooms (HABs)? Freshwater and marine harmful algal blooms (HABs) can occur anytime water use is impaired due to excessive accumulations of algae. HAB occurrence is affected by a complex set of physical, chemical, biological, hydrological, and meteorological conditions making it difficult to isolate specific causative environmental factors. Potential impairments include reduction in water quality, accumulation of malodorous scums in beach areas, algal production of toxins potent enough to poison both aquatic and terrestrial organisms, and algal production of taste-and-odor compounds that cause unpalatable drinking water and fish. HABs are a global problem, and toxic freshwater and (or) marine algae have been implicated in human and animal illness and death in over 45 countries worldwide and in at least 27 U.S. States (Yoo and others, 1995; Chorus and Bartram, 1999; Huisman and others, 2005).

  6. Pregnancy as a harm?

    Kraft, Rory E

    2012-01-01

    Michigan's Appellate Court ruled in 2004 that a pregnancy that resulted from a rape should be considered a bodily injury for sentencing purposes. Interestingly, all three possible outcomes of a pregnancy-abortion, miscarriage, or childbirth-are considered to bring with them significant and substantial physical, psychological, and emotional changes. While the immediate impact of the ruling in People v. Cathey affected only the guilty individual, there are larger implications for this ruling beyond just sentencing guidelines. The ruling can be considered a step forward in prosecuting rapists, but possibly at the expense of reimagining the female body. This article considers the Cathey ruling itself, the potential benefits and consequences of this understanding on feminist discourse, and, crucially, the impact of this decision on abortion discussions. The central question that emerges is, can we both consider pregnancy a harm and believe that this harm is not always wrong-making?

The most important results of these investigations are reported in the present paper.

  13. Islam and harm reduction.

    Kamarulzaman, A; Saifuddeen, S M

    2010-03-01

    Although drugs are haram and therefore prohibited in Islam, illicit drug use is widespread in many Islamic countries throughout the world. In the last several years increased prevalence of this problem has been observed in many of these countries which has in turn led to increasing injecting drug use driven HIV/AIDS epidemic across the Islamic world. Whilst some countries have recently responded to the threat through the implementation of harm reduction programmes, many others have been slow to respond. In Islam, The Quran and the Prophetic traditions or the Sunnah are the central sources of references for the laws and principles that guide the Muslims' way of life and by which policies and guidelines for responses including that of contemporary social and health problems can be derived. The preservation and protection of the dignity of man, and steering mankind away from harm and destruction are central to the teachings of Islam. When viewed through the Islamic principles of the preservation and protection of the faith, life, intellect, progeny and wealth, harm reduction programmes are permissible and in fact provide a practical solution to a problem that could result in far greater damage to the society at large if left unaddressed.

    This article focuses on how recreational drug users in the Netherlands and in online communities navigate the risks and reduce the harms they associate with psychoactive drug use. To do so, we examined the protective practices they invent, use, and share with their immediate peers and with larger drug experimenting communities online. The labor involved in protective practices and that which ultimately informs harm reduction from below follows three interrelated trajectories: (1) the handling and sharing of drugs to facilitate hassle-free drug use, (2) creating pleasant and friendly spaces that we highlight under the practices of drug use attunements, and (3) the seeking and sharing of information in practices to spread the good high. We focus not only on users’ concerns but also on how these concerns shape their approach to drugs, what young people do to navigate uncertainties, and how they reach out to and create different sources of knowledge to minimize adversities and to improve highs. Harm reduction from below, we argue, can best be seen in the practices of sharing around drug use and in the caring for the larger community of drug-using peers. PMID:27721525

    This study aims to investigate smoking patterns in high school student and to give student smoker effective information. The sample of 250 male high school students out of two different schools in Tae-Jŏn was questioned from July 10th to 15th, 1995. In analyzing these date, the statistics shows the realities by means of number of students. The results are summarized into 17 items as follows. Regarding the level of smoking, 140 students out of 250 admit that they have ever smoked, 52.1% of smoking students say that the motivation of beginning smoking is mainly curiosity. The survey shows that 22.9% of smoking students feel very good when smoking. It also shows that 30.0% of smoking students began smoking in the first grade of high school. With regard to the volume of smoking per day, 41.4% of smoking students smoke variably, 42.1% drink when smoking, 15.0% spend more than W 70,000 a month. About the question who knows the fact of their smoking, 51.5% answer that their friends know the fact of their smoking. In regard to the reslationship between smoking and school performance, 18.2% of non smoking students make poor grades as compared with 40% of smoking students, 9.3% of smoking students say that they are satisfied with the school life, but 35.7% of them are not satisfied. Regarding the attitude to smoking teachers, 35% of smoking students state that they are affected by them. 69.3% of smoking students say that they will stop smoking, while the remaining 30.7% say that they will keep smoking. The reason of 63.9% to stop smoking is that smoking is bad for the health. The reason of 46.5% to keep smoking is the acquired habit of smoking. 97.2% know the fact that the major element of cigarettes is nicotine and it is very harmful to the health. 40.8% recognize the harmful effect of smoking by TV and radio programs. 97.2% know that smoking could cause lung cancer.

    The harmful effects of smoking during pregnancy have been well documented within the literature (Eastham and Gosakan 2010; British Medical Association (BMA) 2004). However, although the number of women smoking during pregnancy has fallen over the last few years, this still remains a major health concern for both women and their families. This paper aims to explore recent media campaigns and social policies focusing on smoking in pregnancy and the general population. Midwives need to be aware of current policies with regard to smoking cessation to enable high quality evidence based information and support to be provided at an optimum time in women's lives.

    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.

  19. Harm reduction and the medicalisation of tobacco use.

    2013-03-01

    In tobacco control the focus has, for some time, been on abstinence from all types of tobacco use as the only solution to the problem of smoking, and harm reduction approaches are controversial. The most recent English tobacco strategy has incorporated harm reduction approaches in the form of new 'routes' to quitting smoking that encourage those who cannot quit to use safer sources of nicotine. This move away from a focus on abstinence can be seen as the result of gradual shifts over the past 50 years in the way that that the problem of smoking is understood and the solutions that are offered. These shifts have involved increasingly seeing tobacco use as a medical problem. This article uses conceptual tools from science and technology studies to examine developments over the last decade in England, primarily the increasing importance of harm reduction approaches. Drawing on 20 semi-structured qualitative interviews with key stakeholders and documentary analysis, I suggest that the shape harm reduction has taken in English tobacco control policy has been another shift towards the medicalisation of tobacco use, but that this process has occurred in ways that provide a contrast to commonly outlined 'drivers' of medicalisation.

  20. Acute toxicant exposure and cardiac autonomic dysfunction from smoking a single narghile waterpipe with tobacco and with a “healthy” tobacco-free alternative

    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

    2008-05-01

    We conducted a comparative analysis of "harm," "harm reduction," and "little cigar" information about cigars on 10 major English-language health Web sites. The sites were from governmental and nongovernmental organizations based in seven different countries and included "harm" and "harm reduction" information, discussions of little cigars, quantitative estimates of health risks, and qualifying behavioral characteristics (inhalation, number per day). Of the 10 Web sites, 7 offered statements explicitly indicating that cigars may be safer than cigarettes. None of the Web sites reviewed described that little cigars are likely as dangerous as cigarettes. Some Web sites provided quantitative estimates of health risks and extensive discussions of qualifying factors. Reading grade levels were higher than desirable. Extensive and complex information on the reduced risks of cigars compared with cigarettes is available on Web sites affiliated with prominent health organizations. Yet these sites fail to warn consumers that popular cigarette-like little cigars and cigarillos are likely to be just as dangerous as cigarettes, even for those who have never smoked cigarettes. Improvement of these Web sites is urgently needed to provide the public with high-quality health information.

    The phenomenon of "social smoking" emerged in the past decade as an important area of research, largely due to its high prevalence in young adults. The purpose of this study was to identify classes of young adult ever smokers based on measures of social and contextual influences on tobacco use. Latent class models were developed using social smoking measures, and not the frequency or quantity of tobacco use. Data come from a national sample of young adult ever smokers aged 18-24 (Truth Initiative Young Adult Cohort Study, N=1564). The optimal models identified three latent classes: Class 1 - nonsmokers (52%); Class 2 - social smokers (18%); and Class 3 - smokers (30%). Nearly 60% of the "social smoker" class self-identified as a social smoker, 30% as an ex-smoker/tried smoking, and 12% as a non-smoker. The "social smoker" class was most likely to report using tobacco mainly or only with others. Past 30-day cigarette use was highest in the "smoker" class. Hookah use was highest in the "social smoker" class. Other tobacco and e-cigarette use was similar in the "social smoker" and "smoker" classes. Past 30-day tobacco and e-cigarette use was present for all products in the "non-smoker" class. Young adult social smokers emerge empirically as a sizable, distinct class from other smokers, even without accounting for tobacco use frequency or intensity. The prevalence of hookah use in "social smokers" indicates a group for which the social aspect of tobacco use could drive experimentation and progression to regular use.

    Many fathers mitigate the harm of their smoking by physically separating their smoking from their children and child care activities.The aim of this study was to empirically locate smoking and masculinities by detailing the highly gendered nature of the everyday places where fathers smoke. A masculinities framework was used to interpret interview and photovoice data drawn from an ethnographic study of fathers who smoke. Twenty participants completed individual interviews and contributed a total of 308 photographs to illustrate smoking through the eyes of fathers. The data were analyzed to describe the locations and contexts that facilitate and restrict participants' smoking. Three thematic findings-smoking on the job, the bifurcated domestic sphere, and solitary confinement-were drawn from the analyses to provide insights about when and where smoking does and does not occur, and offer direction for father-centered tobacco reduction interventions.

    Research demonstrated that by reformulating smoking warnings into questions, defensive responses in smokers are reduced and smoking-related risk perception increases. We explored whether these positive outcomes can be generalised to actual behaviour. Participants saw either a movie presenting subheadings with smoking-related questions or statements. Afterwards, the time was measured until participants lit their first cigarette. Smokers who were presented with questions about the harms of smoking waited longer before lighting up a cigarette than smokers who were presented with statements. Presenting questions instead of the statements seems to be an effective means to prolonging smokers' abstinence.

    Smoking is harmful to the health of adolescents because their bodies are still growing. The aim of this study was to analyze the association between the smoking status of Korean adolescents’ parents and friends and their own smoking behavior. The study assessed a nationwide sample of 72,060 middle and high students from the 10th Korea Youth Risk Behavior Web-based Survey (2014). Descriptive analysis, chi-square tests, and multiple logistic regression analysis were used to probe the association between family and friend smoking status and adolescent smoking behavior. The current cigarette smoking rates were 13.3% of boys and 4.1% of girls. The corresponding rates for electronic cigarette smoking were 4.1% and 1.5%, respectively. Higher exposure to secondhand smoke, smoking by any family member, more friends smoking, and witnessed smoking at school were associated with current smoking and electronic smoking. The smoking status of family and friends was significantly related to adolescent smoking behavior. These results should be considered in designing programs to control adolescent smoking.

  9. Tobacco harm reduction: an alternative cessation strategy for inveterate smokers

    2006-01-01

    According to the Centers for Disease Control and Prevention, about 45 million Americans continue to smoke, even after one of the most intense public health campaigns in history, now over 40 years old. Each year some 438,000 smokers die from smoking-related diseases, including lung and other cancers, cardiovascular disorders and pulmonary diseases. Many smokers are unable – or at least unwilling – to achieve cessation through complete nicotine and tobacco abstinence; they continue smoking despite the very real and obvious adverse health consequences. Conventional smoking cessation policies and programs generally present smokers with two unpleasant alternatives: quit, or die. A third approach to smoking cessation, tobacco harm reduction, involves the use of alternative sources of nicotine, including modern smokeless tobacco products. A substantial body of research, much of it produced over the past decade, establishes the scientific and medical foundation for tobacco harm reduction using smokeless tobacco products. This report provides a description of traditional and modern smokeless tobacco products, and of the prevalence of their use in the United States and Sweden. It reviews the epidemiologic evidence for low health risks associated with smokeless use, both in absolute terms and in comparison to the much higher risks of smoking. The report also describes evidence that smokeless tobacco has served as an effective substitute for cigarettes among Swedish men, who consequently have among the lowest smoking-related mortality rates in the developed world. The report documents the fact that extensive misinformation about ST products is widely available from ostensibly reputable sources, including governmental health agencies and major health organizations. The American Council on Science and Health believes that strong support of tobacco harm reduction is fully consistent with its mission to promote sound science in regulation and in public policy, and to assist

    A panel of nine experts applied multi-criteria decision analysis (MCDA) to determine the relative overall harm to users and harms to others of street heroin (injected and smoked) and eleven non-medically used prescription opioids. The experts assessed harm scores for each of the 13 opioids on each of 20 harm criteria, weighted the criteria and explored the resulting weighted harm scores for each opioid. Both forms of heroin scored very high: overall harm score of 99 for injected heroin and 72 for smoked heroin on a scale of 0-100. The main feature that distinguishes both forms of street heroin use is that their harm to others is more than five times that of the other eleven opioids. The overall harm score of fentanyl (including injection of fentanyl extracted from patches) and diamorphine (medically prescribed form of heroin) was 54 and 51, respectively, whereas that of orally used opioids ranged from 32 (pethidine) to 11 (codeine-containing pharmaceuticals). Injected street heroin, fentanyl and diamorphine emerged as most harmful to users, with the latter two very low in harm to others. Pethidine, methadone, morphine and oxycodone are also low in harm to others, while moderate in harm to users. We conclude that the overall harms of non-medically used prescription opioids are less than half that of injected street heroin. These data may give a basis for precautionary regulatory measures that should be considered if the rising trend in non-medical use of prescription opioids were to become evident in the UK.

    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

    To examine the impact of low-intensity continuous training program on antioxidant defense capability and lipid profile in male cigarette or hookah smokers. Forty-three male adults participated in a 12-week continuous training program at an intensity of 40% of VO2max. All subjects were subjected to anthropometric, physical and biochemical tests before and after the training program. The increase of Glutathione reductase (GR) and Superoxide dismutase (SOD) is significant only for cigarette smokers (CS) and hookah smokers (HS) groups. The Malondialdehyde (MDA) decrease and α-tocopherol increase are significant only for HS group. GPx was increased in NS, CS and HS by 2.6% (p< 0.01), 2% (p< 0.05) and 1.7% (p< 0.05) respectively. Likewise, significant improvements of high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and TC / HDL-C ratio were observed in three groups. En contrast no significant changes were recorded in triglycerides (TG). Also, significant reduction of total cholesterol (TC) for CS group (p< 0.01) and HS groups (p< 0.05). This continuous training program appears to have an important role in lipid levels improving and oxidative stress attenuation. PMID:26121249

    Reducing the prevalence of smoking in pregnancy is a priority target for health care. We administered a semi-structured questionnaire to mothers in an inner city general practice who were given brief anti-smoking advice during routine antenatal care. Of a cohort of 113 mothers, 52(46%) reported smoking at the start of pregnancy. Six(12%) of these 52 smokers reported no change in smoking habit during pregnancy; 24(46%) cut down; 12(23%) stopped; 10(19%) increased their cigarette consumption. Of the 52 smokers, 41(79%) believed smoking was harmful to an unborn baby, yet 30(73%) of these women continued smoking. Almost all recalled having been given anti-smoking advice by the GP and/or hospital. There is an urgent need to identify more effective methods of reducing smoking in pregnancy. PMID:12137158

    While the harmful health effects of carbon monoxide, nicotine, tar, irritants and other noxious gases that are present in tobacco smoke are well known, those due to heavy metals and other toxic mineral elements in tobacco smoke are not sufficiently emphasized. Tobacco smoking influences the concentrations of several elements in some organs. This review summarizes the known effects of some trace elements and other biochemically important elements (Al, As, Cd, Cr, Cu, Pb, Mn, Hg, Ni, Po-210, Se, and Zn) which are linked with smoking. Cigarette smoking may be a substantial source of intake of these hazardous elements not only to the smoker but also, through passive smoking, to nonsmokers. The adverse health effects of these toxic elements on the fetus through maternal smoking, and on infants through parental smoking, are of special concern. PMID:1600587

    2014-11-01

    Smoking causes around 100,000 deaths each year in the UK, and is the leading cause of preventable disease and early mortality. Smoking cessation remains difficult and existing licensed treatments have limited success. Nicotine addiction is thought to be one of the primary reasons that smokers find it so hard to give up, and earlier this year DTB reviewed the effects of nicotine on health. Electronic cigarettes (e-cigarettes) are nicotine delivery devices that aim to mimic the process of smoking but avoid exposing the user to some of the harmful components of traditional cigarettes. However, the increase in the use of e-cigarettes and their potential use as an aid to smoking cessation has been subject to much debate. In this article we consider the regulatory and safety issues associated with the use of e-cigarettes, and their efficacy in smoking cessation and reduction.

    2016-11-30

    There is debate in the tobacco control literature about the value of a medical model in reducing smoking-related harm. The variety of medical treatments for smoking cessation has increased, health professionals are encouraged to use them to assist smoking cessation and tobacco dependence is being described as a 'chronic disease'. Some critics suggest that the medicalisation of smoking undermines the tobacco industry's responsibility for the harms of smoking. Others worry that it will lead smokers to deny personal responsibility for cessation, create beliefs in 'magic bullets' for smoking cessation, or erode smokers' confidence in their ability to quit. We argue that the medicalisation of smoking will have limited impact due to the emphasis on population-based interventions in tobacco control, the ambiguous place of nicotine among other drugs and the modest efficacy of current pharmacotherapies. These factors, as well as lay understandings of smoking that emphasise willpower, personal choice and responsibility, have contributed to the limited success of medical approaches to smoking cessation. While the rapid uptake of e-cigarettes in some countries has provided an option for those who reject medical treatments for smoking cessation, current regulatory developments could limit the potential of e-cigarettes to provide non-therapeutic nicotine for those who currently smoke tobacco.

    Aim: To compare air nicotine levels in public places in Ahmedabad, India, before (June 2008) and after (January, 2010) the implementation of a comprehensive smoking ban which was introduced in October 2008. Materials and Methods: Air nicotine concentrations were measured by sampling of vapor-phase nicotine using passive monitors. In 2008 (baseline), monitors were placed for 5-7 working days in 5 hospitals, 10 restaurants, 5 schools, 5 government buildings, and 10 entertainment venues, of which 6 were hookah bars. In 2010 (follow-up), monitors were placed in 35 similar venues for the same duration. Results: Comparison of the overall median nicotine concentration at baseline (2008) (0.06 μg/m3 Interquartile range (IQR): 0.02-0.22) to that of follow-up (2010) (0.03 μg/m3 IQR: 0.00-0.13), reflects a significant decline (% decline = 39.7, P = 0.012) in exposure to second-hand smoke (SHS). The percent change in exposure varied by venue-type. The most significant decrease occurred in hospitals, from 0.04 μg/m3 at baseline to concentrations under the limit of detection at follow-up (%decline = 100, P < 0.001). In entertainment venues, government offices, and restaurants, decreases in SHS exposure also appeared evident. However, in hookah bars, air nicotine levels appeared to increase (P = 0.160). Conclusion: Overall, SHS exposure was significantly reduced in public places after the smoke-free legislation came into force. However, nicotine concentrations were still detected in most of the venues indicating imperfect compliance with the comprehensive ban. PMID:25657509

    Tobacco consumption is a major public health threat. Midwives can contribute to the reduction of tobacco use among pregnant women and young families. It can be assumed that personal smoking behaviour and knowledge of harmful effects influences counselling activities. The aim of this study was to assess smoking status, nicotine dependency and the will to change of midwifery students in german-speaking countries. Broad data on this population is not available so far. In 2010, a self-administered questionnaire survey was conducted among Austrian, German and Swiss midwifery schools. Sociodemographic characteristics, smoking habits, personal attitudes towards smoking, knowledge of cessation strategies, perceived self-efficacy and competence to counsel pregnant women regarding their smoking habits of midwifery trainees were examined. 1 126 students and 38 teaching midwives answered this questionnaire (RR=61.8%). 22.7% are daily or occasional smokers. 6.8% have to be considered as medium and heavy smokers. 98.1% consider cessation counselling for pregnant and breast-feeding women as a midwife's task, while 76.5% feel competent enough to do so. 75.5% rate cessation counselling through midwives as effective stop-smoking procedures compared to blurry knowledge on related health risks and effective stop-smoking strategies. The self-reported smoking prevalence is considerably lower than in previous studies and other populations. Knowledge of harmful effects and of effective treatment options needs improvement. Counselling competence needs to be included in a broader way in midwifery curricula.

    Due to their similarity to tobacco cigarettes, electronic cigarettes (e-cigarettes) could play an important role in tobacco harm reduction. However, the public health community remains divided concerning the appropriateness of endorsing a device whose safety and efficacy for smoking cessation remain unclear. We identified the major ethical considerations surrounding the use of e-cigarettes for tobacco harm reduction, including product safety, efficacy for smoking cessation and reduction, use among non-smokers, use among youth, marketing and advertisement, use in public places, renormalization of a smoking culture, and market ownership. Overall, the safety profile of e-cigarettes is unlikely to warrant serious public health concerns, particularly given the known adverse health effects associated with tobacco cigarettes. As a result, it is unlikely that the population-level harms resulting from e-cigarette uptake among non-smokers would overshadow the public health gains obtained from tobacco harm reduction among current smokers. While the existence of a gateway effect for youth remains uncertain, e-cigarette use in this population should be discouraged. Similarly, marketing and advertisement should remain aligned with the degree of known product risk and should be targeted to current smokers. Overall, the available evidence supports the cautionary implementation of harm reduction interventions aimed at promoting e-cigarettes as attractive and competitive alternatives to cigarette smoking, while taking measures to protect vulnerable groups and individuals.

    Background The main objectives of this study are to describe the smoked cocaine user's profile in socially-depressed areas and their needs from a harm-reduction perspective, to investigate their use of smoking crack and compare the acute effects between injecting and smoking consumption. Methods The study took place in SAPS, Barcelona, Spain. Two focus group sessions were undertaken with a total of 8 drug users. Secondly, the 8 participants answered a structured questionnaire and in the course of the sessions, as a snowball activity, were trained to survey 6 other crack smokers. Results We obtained 56 questionnaires. The majority of participants were from non-European Community countries (62.69%), 70.2% of participants referred to sharing the smoking equipment. The most frequent symptoms reported during smoked cocaine were mydriasis (83.33%)), perspiration (72.92%) and compulsive object search (70.83%) During the group sessions, participants said that smoked cocaine is much more addictive than injected cocaine and causes more anxiety. Participants also reported the difficulty of changing from injected use to smoked use, due to the larger amount of cocaine needed to reach the same effects as when having injected. Conclusions We can conclude that the research, focused on achieving greater knowledge of the smoked cocaine user's profile, their usage of smoking crack, consumption patterns and acute effects, should be incorporated into substance misuse interventions.

    Since implementation of the New Smoking Cessation Policy in Taiwan, more patients are attending smoking cessation clinics. Many of these patients were referred by hospital staff. Thus, factors which influence the hospital staff's willingness to refer are important. In this study, we aim to understand the relation between smoking cessation knowledge and willingness for referral. A cross-sectional study using a questionnaire was conducted with staff of a community hospital during the year 2012-2013. Willingness to provide smoking cessation referral and relevant correlated variables including demographic data, knowledge of basic cigarette harm, and knowledge of resources and methods regarding smoking cessation were measured. A total of 848 of 1500 hospital staff returned the questionnaire: 249 physicians (29.4%), 402 nursing staff (47.4%), and 197 administration staff (23.2%). 790 (93.2%) staff members have never smoked, 19 (2.2%) had quit smoking, and 39 (4.6%) still smoke. 792 (93.4%) members had interest in receiving smoking cessation education. The mean total score (highest potential score of 6) of basic cigarette harm knowledge was 4.56 (± 1.25). The mean total score (highest potential score of 7) of resources and methods about smoking cessation was 4.79 (± 1.35). The significant variable correlated with willingness to refer was total score of resources and methods about smoking cessation. Hospital staff who knew more about resources and methods about smoking cessation were more willing to refer smoking patients to the smoking cessation service. Thus, continuing medical education for hospital staff should include resources and methods about smoking cessation to promote smoking cessation.

    The objectives of this review were to determine whether the smoking paradox still exists and to summarize possible explanations for the smoking paradox. Based on published data, we compared the risk of cigarette smoking for lung cancer in Western and Asian countries. We extracted data from the relevant studies about annual tobacco consumption, lung cancer mortality rates according to smoking status from each country, and possible explanations for the smoking paradox. A significantly greater risk of lung cancer death was found among current smokers in Asian countries than among nonsmokers, with relative risks (RRs) of 4.0 to 4.6 for Koreans, 3.7 to 5.1 for Japanese, and 2.4 to 6.5 for Chinese. Although a significantly greater risk of lung cancer was present among current smokers in Asian countries, the RRs in Asian countries were much lower than those reported in Western countries (range, 9.4 to 23.2). Possible explanations for the smoking paradox included epidemiologic characteristics, such as the smoking amount, age at smoking initiation, and the use of filtered or mild tobacco. The smoking paradox definitely exists, but may be explained by major epidemiologic characteristics. Therefore, the smoking paradox should not be interpreted as indicating that tobacco is safer or less harmful for Asians.

    By quitting, smokers of all ages can gain substantial health benefits. No other single effort of public health is able to achieve an advantage comparable to smoking cessation on a large scale. However, conventional approaches to smoking cessation require tobacco users to completely abstain, and many smokers are unable - or have not the willingness - to achieve this goal, and then continue to smoke despite the looming negative consequences for health. But it is possible to consider another option: the reduction of harm caused by tobacco smoking (tobacco harm reduction) through the intake of nicotine from alternative sources safer than tobacco smoke, such as the electronic cigarette (e-cig). It is a promising product for the reduction of harm caused by tobacco smoking. In addition to providing nicotine through the vapour without the typical toxic and carcinogenic substances derived from combustion, the e-cig is also a good substitute for the rituals associated with the behaviour of the smoker. In this article, the author suggests that the wide dissemination of vaping behaviour can become a successful strategy to reduce smoking and preventing smoking-related diseases, advancing on how to succeed with this matter.

    Smokers of any age can reap substantial health benefits by quitting. In fact, no other single public health effort is likely to achieve a benefit comparable to large-scale smoking cessation. Surveys document that most smokers would like to quit, and many have made repeated efforts to do so. However, conventional smoking cessation approaches require nicotine addicted smokers to abstain from tobacco and nicotine entirely. Many smokers are unable--or at least unwilling--to achieve this goal, and so they continue smoking in the face of impending adverse health consequences. In effect, the status quo in smoking cessation presents smokers with just two unpleasant alternatives: quit or suffer the harmful effects of continuing smoking. But, there is a third choice for smokers: tobacco harm reduction. It involves the use of alternative sources of nicotine, including modern smokeless tobacco products like snus and the electronic cigarette (E-cig), or even pharmaceutical nicotine products, as a replacement for smoking. E-cigs might be the most promising product for tobacco harm reduction to date, because, besides delivering nicotine vapour without the combustion products that are responsible for nearly all of smoking's damaging effect, they also replace some of the rituals associated with smoking behaviour. Thus it is likely that smokers who switch to E-cigs will achieve large health gains. The focus of this article is on the health effects of using an E-cig, with consideration given to the acceptability, safety and effectiveness of this product as a long-term substitute for smoking.

    Cigarette smoke (CS) is a major risk factor for cardiovascular and lung diseases. Because CS is a complex aerosol containing more than 7,000 chemicals1 it is challenging to assess the contributions of individual constituents to its overall toxicity. Toxicological profiles of individual constituents as well as mixtures can be however established in vitro, by applying high through-put screening tools, which enable the profiling of Harmful and Potentially Harmful Constituents (HPHCs) of tobacco smoke, as defined by the U.S. Food and Drug Administration (FDA).2 For an initial assessment, an impedance-based instrument was used for a real-time, label-free assessment of the compound's toxicity. The instrument readout relies on cell adhesion, viability and morphology that all together provide an overview of the cell status. A dimensionless parameter, named cell index, is used for quantification. A set of different staining protocols was developed for a fluorescence imaging-based investigation and a HCS platform was used to gain more in-depth information on the kind of cytotoxicity elicited by each HPHC. Of the 15 constituents tested, only five were selected for HCS-based analysis as they registered a computable LD50 (< 20 mM). These included 1-aminonaphtalene, Arsenic (V), Chromium (VI), Crotonaldehyde and Phenol. Based on their effect in the HCS, 1-aminonaphtalene and Phenol could be identified to induce mitochondrial dysfunction, and, together with Chromium (VI) as genotoxic based on the increased histone H2AX phosphorylation. Crotonaldehyde was identified as an oxidative stress inducer and Arsenic as a stress kinase pathway activator. This study demonstrates that a combination of impedance-based and HCS technologies provides a robust tool for in vitro assessment of CS constituents. PMID:27228213

    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.

    Tobacco kills 5 million people annually. By the mid 2020s, that figure will increase to about 10 million a year, with most of the deaths occurring in developing countries. This review explains how early technological and regulatory developments contributed to the epidemic, reveals the efforts of the tobacco industry to conceal its products' harmfulness, and stresses the role of the globalization of trade and marketing as a means of increasing consumption world-wide. The results of tens of thousands of studies published globally over the past 50 years point to an association between smoking and lung cancer and other adverse health effects, and the non-smoker's rights movement has exposed the wide-spread perils of 'secondhand' smoke. Yet, the tobacco industry continues its global expansion, and consumers in low- and middle-income countries are especially susceptible to its marketing tactics. This review ends by emphasising the need for a global public-health response, and identifies the Framework Convention on Tobacco Control as a significant effort. It stresses the need for accelerated action and innovative tobacco-control efforts, if the projected death toll is to be reduced in this century.

    A total of 20 commercial cigarette and 16 commercial smokeless tobacco products were assayed for 96 compounds listed as harmful and potentially harmful constituents (HPHCs) by the US Food and Drug Administration. For each product, a single lot was used for all testing. Both International Organization for Standardization and Health Canada smoking regimens were used for cigarette testing. For those HPHCs detected, measured levels were consistent with levels reported in the literature, however substantial assay variability (measured as average relative standard deviation) was found for most results. Using an abbreviated list of HPHCs, statistically significant differences for most of these HPHCs occurred when results were obtained 4-6months apart (i.e., temporal variability). The assay variability and temporal variability demonstrate the need for standardized analytical methods with defined repeatability and reproducibility for each HPHC using certified reference standards. Temporal variability also means that simple conventional comparisons, such as two-sample t-tests, are inappropriate for comparing products tested at different points in time from the same laboratory or from different laboratories. Until capable laboratories use standardized assays with established repeatability, reproducibility, and certified reference standards, the resulting HPHC data will be unreliable for product comparisons or other decision making in regulatory science.

The ban is a result of a 2003 Health Council report in which it was concluded that the annual incidence of deaths due to passive smoking is considerable. Based on these numbers, smoking in public spaces is prohibited since 2004. In a society where smoking in public spaces is prohibited, the harm of passive smoking will decrease.

    Background Smoking remains a serious public health concern. Pharmacotherapy for smoking cessation, including bupropion and varenicline, are proven means to increase quit rates. Post-marketing reports describing suicidal behaviours have raised concerns about the safety of varenicline. However, whether varenicline imparts a higher risk of suicide relative to bupropion remains uncertain. Methods A population-based nested case-control study in Ontario, Canada, from April 1, 2011 to March 31, 2015 was conducted. Subjects were residents of Ontario aged 18 years and older with publicly funded drug coverage receiving either bupropion or varenicline for smoking cessation. We defined cases were those with a hospitalization or emergency department visit for suicide or non-fatal self-harm within 90 days of treatment. For each case, we identified up to fifty controls from the same cohort matched on age, sex, history of self-harm, use of selected psychotropic medications, alcohol abuse and prior admission to a mental health unit. Adjusted odds ratio were used to compare the risk of suicide/self-harm of varenicline to bupropion. Results We identified 331 cases and 5,346 matched-controls. Following adjustment for potential confounders, we found that varenicline was not associated with an increased risk of suicide/self-harm relative to bupropion (adjusted odds ratio 1.15; 95% confidence interval 0.71 to 1.87). Interpretation Treatment with varenicline does not appear to significantly increase the risk of suicide or self-harm relative to bupropion. PMID:27662654

    Evidence of the harmful effects of surgical smoke has been recognized in the literature and by professional organizations for many years, yet surgical smoke continues to pose a safety hazard for patients and perioperative personnel. A team of perioperative nurses and educators sought to improve compliance with policies and procedures for surgical smoke management in the OR. The team quantified smoke-evacuator use, assessed staff members' knowledge using a pre-education survey, and presented a three-part multimodal education program. The team conducted a posteducation survey that showed significant improvement in staff members' knowledge. Ninety-day postimplementation quantitative data showed a 14.6% increase in surgical smoke-evacuation use. This educational initiative increased staff members' awareness about reducing the presence of surgical smoke in the OR and helped ensure a safer environment for patients, staff members, and the surgical team.

    Throughout the world, cigarette smoking is a habit that causes serious health, economic, and social problems. Therefore, many countries have taken an active role to control and to ban smoking. The chronic smoking problem in China is particularly acute because China has the largest population of smokers in the world, over 300 million currently. If 30% of these smokers were to die of smoke-related diseases in the next 20 years, the impact from the more than 90 million premature deaths could be damaging to China. In addition, numerous non-smokers also experience health problems from exposure to environmental tobacco smoke. China's efforts to reduce or to ban smoking in certain public places have not been well-coordinated or enforced compared with those in other countries. Therefore, success has been minimal. Consequently, leaders in China should not be complacent about combating the serious national health problem. A multiprong approach in combination with the MPOWER policy from the World Health Organization that targets different levels of acquisition of the smoking habit must be used. Examples may include the government's reduced reliance on profits from the sale of cigarettes, the elimination of advertisements that encourage smoking among young individuals, the presentation of more graphic illustration of harmful effects from smoking on every pack of cigarettes, higher taxes/prices on cigarettes, and the implementation of enforceable bans on smoking in public places. As shown in other countries, such coordinated effort can be highly effective in the reduction of smoking and can have healthy consequences.

  8. The Olympics and harm reduction?

    The current anti-doping policy (‘war on doping’) resembles the ‘war on drugs’ in several aspects, including a zero-tolerance approach, ideology encroaching on human rights and public health principles, high cost using public money for repression and control, and attempts to shape internationally harmonized legal frameworks to attain its aim. Furthermore, even if for different reasons, both wars seem not to be able to attain their objectives, and possibly lead to more harm to society than they can prevent. The Olympic buzz is mounting and we can expect multiple headlines in the media on doping and anti-doping stories related to this event. In this article we describe current anti-doping policy, reflect on its multiple unplanned consequences, and end with a discussion, if lessons learned from harm reduction experiences in the illicit drugs field could be applied to anti-doping.

    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.

    On November 30, 2016, the US Department of Housing and Urban Development (HUD) published a final rule mandating that public housing authorities it supports prohibit all smoking on their residential premises, including within residents' apartments. The primary rationale for this action was to protect nonsmoking residents from the harms of tobacco smoke exposure. Although the harms of secondhand smoke are clear and the potential for reducing nonsmoking residents' exposure is real, it will be no simple matter to successfully implement the policy requirements set down by HUD. Some challenges to policy implementation will apply to all public housing authorities, and others will be unique to specific settings. By being aware of the benefits of smoke-free public housing as well as the challenges inherent in complying with HUD's rule, public housing authorities stand the best chance of fulfilling the potential of this major policy initiative to significantly improve public health in a vulnerable population.

  11. Comparison of True and Smoothed Puff Profile Replication on Smoking Behavior and Mainstream Smoke Emissions

    PubMed Central

    2015-01-01

    To estimate exposures to smokers from cigarettes, smoking topography is typically measured and programmed into a smoking machine to mimic human smoking, and the resulting smoke emissions are tested for relative levels of harmful constituents. However, using only the summary puff data—with a fixed puff frequency, volume, and duration—may underestimate or overestimate actual exposure to smoke toxins. In this laboratory study, we used a topography-driven smoking machine that faithfully reproduces a human smoking session and individual human topography data (n = 24) collected during previous clinical research to investigate if replicating the true puff profile (TP) versus the mathematically derived smoothed puff profile (SM) resulted in differences in particle size distributions and selected toxic/carcinogenic organic compounds from mainstream smoke emissions. Particle size distributions were measured using an electrical low pressure impactor, the masses of the size-fractionated fine and ultrafine particles were determined gravimetrically, and the collected particulate was analyzed for selected particle-bound, semivolatile compounds. Volatile compounds were measured in real time using a proton transfer reaction-mass spectrometer. By and large, TP levels for the fine and ultrafine particulate masses as well as particle-bound organic compounds were slightly lower than the SM concentrations. The volatile compounds, by contrast, showed no clear trend. Differences in emissions due to the use of the TP and SM profiles are generally not large enough to warrant abandoning the procedures used to generate the simpler smoothed profile in favor of the true profile.

    This cross sectional survey was conducted to determine the support in making Penang UNESCO World Heritage Site (GTWHS) smoke free and to determine the influence of tolerance towards smoking on this support. This is the first phase in making Penang, Malaysia a smoke free state. A multistage sampling process was done to select a sample of respondents to represent the population of GTWHS. Attitude towards smoking was assessed using tolerance as a proxy. A total of 3,268 members of the community participated in the survey. A big majority (n = 2969; 90.9%) of the respondents supported the initiative. Support was lowest among the owners and residents/tenants, higher age groups, the Chinese, men, respondents who had poor knowledge of the places gazetted as smoke free, and respondents with poor knowledge of the health effects on smokers and on passive smokers. The odds (both adjusted and unadjusted) of not supporting the initiative was high among those tolerant to smoking in public areas. Tolerance towards smoking was associated with 80.3% risk of non-support in the respondents who were tolerant to smoking and a 57.2% risk in the population. Health promotion and education concerning the harm of tobacco smoke in Malaysia, which has mainly targeted smokers, must change. Health education concerning the risks of second hand smoke must also be given to non-smokers and efforts should be made to denormalize smoking.

  16. Tobacco harm reduction: the need for new products that can compete with cigarettes.

    PubMed

    Fagerström, Karl Olov; Bridgman, Kevin

    2014-03-01

    Over the last 50 years, the concept of tobacco harm reduction has been well established. It is now understood that nicotine itself is not very harmful and nicotine replacement therapy products have been widely used as an aid to quit, reduce to quit or temporarily abstain from smoking for many years. The popularity of the unlicensed electronic cigarette has increased despite an unknown risk profile and sinus use in Sweden provides strong evidence in support of a harm reduction strategy. The regulatory environment around harm reduction has changed in the UK and is continuing to evolve across the globe. The need for more appealing, licensed nicotine products capable of competing with cigarettes sensorially, pharmacologically and behaviourally is considered by many to be the way forward. The significant positive impact on public health that could be gained from encouraging people to switch from cigarettes to licensed medicinal nicotine products cannot be ignored.

    PubMed

    Sargent, James D

    2005-06-01

    This article examines the evidence that supports an association between seeing smoking depictions in movies and adolescent smoking. The portrayal of tobacco use is common in movies and often is modeled by stars, who, from a social influences standpoint, should be powerful behavior change agents. The results of studies that assess audience responses to tobacco portrayal in movies are remarkably consistent in showing a moderate to strong association between seeing movie smoking and more positive attitudes toward smoking and adolescent smoking initiation. The two published longitudinal studies show an independent link between exposure to movie smoking at baseline and initiation in the future, with estimates of the effect size being remarkably consistent with their cross-sectional counterparts. Pediatricians should support public health campaigns to pressure the movie industry to voluntarily reduce smoking in movies and encourage parents to adhere to the Motion Picture Ratings System to reduce adolescent exposure to this powerful social influence to smoke.

    The Dutch parliament has recently accepted a tax law in which certain groups of alternative therapists can be exempt from VAT. To be eligible for this VAT exemption, the disciplines to which the therapists belong have to meet certain training requirements. In this article it is contended, in agreement with the Royal College of Physicians in the UK, that statutory regulation is inappropriate for disciplines whose therapies are neither of proved benefit nor appropriately tested. It legitimizes harmful therapies. This is illustrated by two serious accidents, previously described in this journal, caused by a chiropractor and a craniosacral therapist.

    A sample of adult Black policyholders of the nation's largest Black-owned life insurance company was surveyed in 1986 to add to limited data on smoking and quitting patterns among Black Americans, and to provide direction for cessation initiatives targeted to Black smokers. Forty per cent of 2,958 age-eligible policyholders for whom current addresses were available returned a completed questionnaire. Population estimates for smoking status agree closely with national estimates for Blacks age 21-60 years: 50 per cent never-smokers; 36 per cent current smokers; 14 per cent ex-smokers. Current and ex-smokers reported a modal low-rate/high nicotine menthol smoking pattern. Current smokers reported a mean of 3.8 serious quit attempts, a strong desire and intention to quit smoking, and limited past use of effective quit smoking treatments and self-help resources. Correlates of motivation to quit smoking were similar to those found among smokers in the general population, including smoking-related illnesses and medical advice to quit smoking, previous quit attempts, beliefs in smoking-related health harms/quitting benefits, and expected social support for quitting. Methodological limitations and implications for the design of needed Black-focused quit smoking initiatives are discussed. PMID:2913836

    Introduction and Aims Harms from second-hand smoke were instrumental in enacting tobacco controls. Documenting negative impacts of harms from others’ drinking (also called second-hand effects of drinking) is vital to increase political will for optimal alcohol policies. We assessed associations between harms from others’ drinking and depression in a national sample of US adults. Design and Methods Using the landline sample from the 2010 National Alcohol Survey (n = 5,388), weighted logistic regression models adjusting for alcohol problems in family of origin, respondent drinking pattern (volume and heaviest drinking), poverty, and other demographics were used to analyze associations between experiencing harms from others’ drinking in the last 12 months with mild to moderate depression (CES-D8; alpha = .92; using cut point ≥8) and current distress. Results Past 12-month family/marital harms, financial troubles, and vandalized property attributed to others’ drinking each was associated with higher depression scores (all p < .001). In a combined model, all harms other than assaults remained highly significant. Similar patterns were found for current distress, but with some specific differences due to measurement and analytic approaches chosen also evident. Discussion Findings suggest recently experiencing particular harms from others’ drinking significantly affects mental health (both depression and distress). This confirms in a US population results recently reported in Australasian samples. Conclusions Studies that quantify the extent to which heavy drinkers victimize others are important for alcohol policy. PMID:26382188

    This study applies qualitative research methods to explore perspectives on cessation among smokers/former smokers recruited from an area of Northern Appalachia. Six focus groups, stratified by age group (18-39 years old and 40 years and older), were conducted among participants (n = 54) recruited from community settings. Participants described varied interest in and challenges with quitting smoking. Smokers 40 years and older more readily endorsed the health risks of smoking and had greater interest in quitting assistance. Participants expressed frustration with the US government for allowing a harmful product (e.g., cigarettes) to be promoted with minimal regulation. Use of social media was robust among both age groups; participants expressed limited interest in various social media/technology platforms for promoting smoking cessation. Findings from this understudied area of northern Appalachia reflect the heterogeneity of this region and contribute novel information about the beliefs, attitudes, and experiences of current and formers smokers with regard to cessation.

    Introduction: This study aims to test the pathways of change from individual exposure to smoke-free legislation on smoking cessation, as hypothesized in the International Tobacco Control (ITC) Conceptual Model. Methods: A nationally representative sample of Dutch smokers aged 15 years and older was surveyed during 4 consecutive annual surveys. Of the 1,820 baseline smokers, 1,012 participated in the fourth survey. Structural Equation Modeling was employed to test a model of the effects of individual exposure to smoke-free legislation through policy-specific variables (support for smoke-free legislation and awareness of the harm of [secondhand] smoking) and psychosocial mediators (attitudes, subjective norm, self-efficacy, and intention to quit) on quit attempts and quit success. Results: The effect of individual exposure to smoke-free legislation on smoking cessation was mediated by 1 pathway via support for smoke-free legislation, attitudes about quitting, and intention to quit smoking. Exposure to smoke-free legislation also influenced awareness of the harm of (secondhand) smoking, which in turn influenced the subjective norm about quitting. However, only attitudes about quitting were significantly associated with intention to quit smoking, whereas subjective norm and self-efficacy for quitting were not. Intention to quit predicted quit attempts and quit success, and self-efficacy for quitting predicted quit success. Conclusions: Our findings support the ITC Conceptual Model, which hypothesized that policies influence smoking cessation through policy-specific variables and psychosocial mediators. Smoke-free legislation may increase smoking cessation, provided that it succeeds in influencing support for the legislation. PMID:22491892

    2015-01-01

    Introduction Many cities around the globe have experienced substantial increases in crack cocaine use. Public health programmes have begun to address crack smoking, primarily through the distribution of safer crack use equipment, but their impacts have been limited. More comprehensive safer environmental interventions, specifically safer smoking rooms (SSR), have been implemented only in select European cities. However, none have been subjected to rigorous evaluation. This ethnographic study was undertaken at an ‘unsanctioned’ SSR operated by a drug user-led organization in Vancouver, Canada, to explore how this intervention shaped crack smoking practices, public crack smoking, and related harms. Methods Ethnographic fieldwork was undertaken at this SSR from September to December 2011, and included approximately 50 hours of ethnographic observation and 23 in-depth interviews with people who smoke crack. Data were analyzed by drawing on the ‘Risk Environment’ framework and concepts of ‘symbolic’, ‘everyday’, and ‘structural’ violence. Findings Our findings illustrate how a high demand for SSRs was driven by the need to minimize exposure to policing (structural violence), drug scene violence (everyday violence), and stigma (symbolic violence) that characterized unregulated drug use settings (e.g., public spaces). Although resource scarcity and social norms operating within the local drug scene (e.g., gendered power relations) perpetuated crack pipe-sharing within unregulated drug use settings, the SSR fostered harm reduction practices by reshaping the social-structural context of crack smoking and reduced the potential for health harms. Conclusion Given the significant potential of SSRs in reducing health and social harms, there is an urgent need to scale up these interventions. Integrating SSRs into public health systems, and supplementing these interventions with health and social supports, has potential to improve the health and safety of crack-smoking

    Background Comprehensive smoke-free laws are effective at protecting non-smokers and reducing tobacco use, yet they are not widely adopted by tribal governments. Methods A series of smoke-free policy initiatives on the Navajo Nation, beginning in 2008, were reviewed to identify key issues, successes and setbacks. Results It has been essential that proposed policies acknowledge the Navajo people's spiritual use of nát'oh, a sacred plant used for gift-giving, medicinal purposes and traditional ceremonies, while simultaneously discouraging a secular use of commercial tobacco. Concern that smoke-free policies economically harm tribal casinos has been a major barrier to broad implementation of comprehensive smoke-free laws in Navajo Nation. Conclusions It is necessary for tobacco control researchers and advocates to build relationships with tribal leaders and casino management in order to develop the business case that will take comprehensive smoke-free policies to scale throughout tribal lands.

    PubMed

    Aronoff, J; Lynn, S J; Malinoski, P

    2000-01-01

    This article is the first critical review of research that addresses the question of whether cult membership is psychologically harmful. The available evidence warrants three conclusions: (a) persons entering cults do not necessarily exhibit psychopathology; (b) current cult members appear psychologically well-adjusted generally, and demonstrate few conspicuous symptoms of psychopathology. However, pathology may be masked by conformity pressures and demand characteristics associated with the cultic environment; (c) a small but growing body of research indicates that at least a substantial minority of former cult members experience significant adjustment difficulties. There also are indications that these difficulties cannot be ascribed to demand characteristics. Although the review highlights definitional and methodological issues and problems that temper conclusions that can be drawn from the literature, no evidence indicates that cults improve adjustment after members leave the cultic environment.

    Issue addressed: The smoking rate among male Chinese migrants in Australia is higher than among the general population. This study investigated the smoking rate of male Chinese restaurant workers in metropolitan Sydney, and explored factors associated with smoking and quitting.Methods: A self-administered questionnaire survey was completed by Chinese workers in selected Chinese restaurants in metropolitan Sydney from October-December 2012. Eighty-nine Chinese restaurants were approached and 54 (61%) took part in the study. The questionnaire asked participants about their smoking status, knowledge of and attitudes to smoking and quitting as well as socio-demographic information. Multivariable logistic regression was built to assess the associated factors.Results: Of the 382 participants who completed the survey, 171 (45%) were current smokers and 50% of current smokers wanted to quit smoking. Participants who spoke Mandarin, had lower English proficiency, did not realise environmental smoke harms children, did not prefer a smoke-free environment or had more than 50% of relatives or friends who smoked were more likely to be current smokers. Participants who were aged 18-29 years, did not understand the benefits of quitting smoking or did not prefer a smoke-free environment were less likely to want to quit.Conclusions: Nearly 50% of male Chinese restaurant workers surveyed in this study were current smokers. Key factors associated with the participants' smoking or quitting status are: aged 18-29 years; speaking Mandarin; lower English literacy; and not knowing the dangers of smoking.So what?: Tobacco control programs targetted at male Chinese restaurant workers that raise awareness of the harm caused by smoking and the benefits of quitting smoking are required to enhance intention to quit smoking within this population.

    The prevalence of adolescent smoking has been increasing rapidly in China. Expanding adolescent exposure to antismoking messages may be an effective approach to prevent tobacco use among this population. Using a cross-sectional sample of 8,444 high school students in four Chinese cities, this study assessed the relation between self-reported exposure to antismoking messages from families, schools, and mass media and the rate of past 30-day smoking and smoking intention among junior and senior high school students. Results from logistic regression suggested that antismoking messages delivered via school and media inhibited both tobacco use and the intention to smoke. The effects of familial warnings about harmful effects of smoking, in contrast, were at best insignificant.

    Laws and treaties compel countries to inform the public about harmful chemicals (constituents) in cigarette smoke. To encourage relevant research by behavioral scientists, we provide a primer on cigarette smoke toxicology and summarize research on how the public thinks about cigarette smoke chemicals. We systematically searched PubMed in July 2016 and reviewed citations from included articles. Four central findings emerged across 46 articles that met inclusion criteria. First, people were familiar with very few chemicals in cigarette smoke. Second, people knew little about cigarette additives, assumed harmful chemicals are added during manufacturing, and perceived cigarettes without additives to be less harmful. Third, people wanted more information about constituents. Finally, well-presented chemical information increased knowledge and awareness and may change behavior. This research area is in urgent need of behavioral science. Future research should investigate whether educating the public about these chemicals increases risk perceptions and quitting.

    2013-01-01

    The tobacco problem can be usefully conceptualised as two problems: eliminating the most harmful forms of nicotine use (certainly cigarettes, and probably all smoked tobacco), and minimising the use and/or harms from use of lower-harm, but addictive forms of nicotine. A possible target would be to effectively eliminate use of the most harmful forms of nicotine within the next decade and then turn our focus to a long-term strategy for the low-harm forms. This paper focuses on the administrative framework(s) needed to accomplish these twin tasks. For a phase-out taking a long time and/or for dealing with residually net harmful and addictive products, there are severe limitations to allowing for-profit marketing of tobacco because such an arrangement (the current one in most countries) can markedly slow down progress and because of the difficulty of constraining marketing in ways that minimise undesirable use. A harm reduction model where the marketing is under the control of a non-profit entity (a regulated market) is required to curtail the incredible power of for-profit marketing and to allow tobacco marketing to be done in ways that further the goal of minimising tobacco-related harm. Countries with a nationalised industry can move their industry onto a harm minimisation framework if they have the political will. Countries with a for-profit industry should consider whether the time and effort required to reconstruct the market may, in the longer term, facilitate achieving their policy goals. PMID:23591515

    2016-01-01

    Introduction Low and middle income countries bear the majority burden of self-harm, yet there is a paucity of evidence detailing risk-factors for self-harm in these populations. This study aims to identify environmental, socio-economic and demographic household-level risk factors for self-harm in five impoverished urban communities in Johannesburg, South Africa. Methods Annual serial cross-sectional surveys were undertaken in five impoverished urban communities in Johannesburg for the Health, Environment and Development (HEAD) study. Logistic regression analysis using the HEAD study data (2006–2011) was conducted to identify household-level risk factors associated with self-harm (defined as a self-reported case of a fatal or non-fatal suicide attempt) within the household during the preceding year. Stepwise multivariate logistic regression analysis was employed to identify factors associated with self-harm. Results A total of 2 795 household interviews were conducted from 2006 to 2011. There was no significant trend in self-harm over time. Results from the final model showed that self-harm was significantly associated with households exposed to a violent crime during the past year (Adjusted Odds Ratio (AOR) 5.72; 95% CI 1.64–19.97); that have a member suffering from a chronic medical condition (AOR 8.95; 95% 2.39–33.56) and households exposed to indoor smoking (AOR 4.39; CI 95% 1.14–16.47). Conclusion This study provides evidence on household risk factors of self-harm in settings of urban poverty and has highlighted the potential for a more cost-effective approach to identifying those at risk of self-harm based on household level factors.

  17. The scientific foundation for tobacco harm reduction, 2006-2011

    PubMed Central

    2011-01-01

    Over the past five years there has been exponential expansion of interest in tobacco harm reduction (THR), with a concomitant increase in the number of published studies. The purpose of this manuscript is to review and analyze influential contributions to the scientific and medical literature relating to THR, and to discuss issues that continue to stimulate debate. Numerous epidemiologic studies and subsequent meta-analyses confirm that smokeless tobacco (ST) use is associated with minimal risks for cancer and for myocardial infarction; a small increased risk for stroke cannot be excluded. Studies from Sweden document that ST use is not associated with benign gastrointestinal disorders and chronic inflammatory diseases. Although any form of nicotine should be avoided during pregnancy, the highest risks for the developing baby are associated with smoking. It is documented that ST use has been a key factor in the declining rates of smoking and of smoking-related diseases in Sweden and Norway. For other countries, the potential population health benefits of ST are far greater than the potential risks. In follow-up studies, dual users of cigarettes and ST are less likely than exclusive smokers to achieve complete tobacco abstinence, but they are also less likely to be smoking. The health risks from dual use are probably lower than those from exclusive smoking. E-cigarette users are not exposed to the many toxicants, carcinogens and abundant free radicals formed when tobacco is burned. Although laboratory studies have detected trace concentrations of some contaminants, it is a small problem amenable to improvements in quality control and manufacturing that are likely with FDA regulation as tobacco products. There is limited evidence from clinical trials that e-cigarettes deliver only small doses of nicotine compared with conventional cigarettes. However, e-cigarette use emulates successfully the cigarette handling rituals and cues of cigarette smoking, which produces

    Electrosurgical equipment used during surgery generate smoke consisting of particles, vapor, aerosols and potentially harmful biological agents. Smoke evacuation systems are used more commonly and various types are available. A special image enhancement technique was used to study the behavior of surgical smoke and the effectiveness of smoke evacuation systems. Three different smoke evacuation systems were investigated. Rapid vac (Valleylab Boulder CO) The Buffalo silent whisper turbo (Buffalo, NY) ERBE IES 300 ( Tübingen, Germany) A back scatter illumination technique in combination with a high speed camera was applied to image the dynamics of a smoke plume generated by vaporizing a homogenous meat paste irradiated with the beam of a 10 W cw CO2 laser moving at a constant speed. The three different smoke evacuation systems with their individual nozzles, were held 2 cm above the surface of the meat paste and were switched on and off at fixed intervals to mimic a clinical situation. For images analysis, software was developed to count 'smoke pixels' in the video frames as a quantification tool. For the observer's eye, there were no differences between the systems. However, images quantification showed significantly less 'smoke' for the Buffalo system. It is expected that the performance in a clinical situation is also influenced by additional conditions like nozzle design, airflow and noise level. Noise levels were measured at the tip of the nozzle, 80 cm from the tip, 140 cm from the tip. The Buffalo system is the loudest system at every distance measured.

    2015-01-01

    Cigarette smoking (CS) is a major health hazard that exerts diverse physiologic and biochemical effects mediated by the components present and generated during smoking. Recent experimental studies have shown predisposition to several biological consequences from both active and passive cigarette smoke exposure. In particular, passive smoking is linked to a number of adverse health effects which are equally harmful as active smoking. A pragmatic approach should be considered for designing a pharmacological intervention to combat the adverse effects of passive smoking. This review describes the results from a controlled experimental condition, testing the effect of bacoside A (BA) on the causal role of passive/secondhand smoke exposure that caused pathological and neurological changes in rat brain. Chronic exposure to cigarette smoke induced significant changes in rat brain histologically and at the neurotransmitter level, lipid peroxidation states, mitochondrial functions, membrane alterations, and apoptotic damage in rat brain. Bacoside A is a neuroactive agent isolated from Bacopa monnieri. As a neuroactive agent, BA was effective in combating these changes. Future research should examine the effects of BA at molecular level and assess its functional effects on neurobiological and behavioral processes associated with passive smoke. PMID:26413118

  20. Toward a psychology of harm reduction.

    This article discusses 3 different strategies for dealing with the harmful consequences of drug use and other risky behaviors: We can discourage people from engaging in the behavior (prevalence reduction), we can encourage people to reduce the frequency or extent of the behavior (quantity reduction), or we can try to reduce the harmful consequences of the behavior when it occurs (harm reduction). These strategies are not mutually exclusive; this article offers a framework for integrating them. The framework is useful for examining frequent claims that harm reduction "sends the wrong message." Opposition to harm reduction is based in part on a recognition of potential trade-offs among the strategies, but it is also fueled by several more symbolic psychological factors. Strategies for successfully integrating prevalence reduction, quantity reduction, and harm reduction are explored.

    Awareness and use of electronic cigarettes (e-cigarettes) is increasing. Questions regarding positive (e.g., smoking reduction/cessation) and negative (e.g., delay of cessation) potential public health consequences of e-cigarettes may be informed by studying dual users of e-cigarettes and tobacco cigarettes. A cross-sectional online survey assessed demographics, product use patterns, and beliefs about relative product benefits and harms among dual users (n = 350) in the United States using the website Amazon Mechanical Turk. Compared to tobacco cigarettes, e-cigarettes were used less often and were associated with lower dependence. Participants reported a 30% reduction in self-reported tobacco cigarette smoking since beginning to use e-cigarettes. Reported primary reasons for e-cigarette use were harm reduction and smoking cessation. E-cigarette use was reported as more likely in settings with smoking restrictions and when others' health could be adversely affected. Conversely, participants reported having used tobacco cigarettes more often than e-cigarettes in hedonic situations (e.g., after eating, drinking coffee or alcohol, or having sex), outdoors, or when stressed. Participants were twice as likely to report wanting to quit tobacco cigarettes compared to e-cigarettes in the next year and intended to quit tobacco cigarettes sooner. Tobacco cigarettes were described as more harmful and addictive, but also as more enjoyable than e-cigarettes. Participants provided evidence consistent with both positive and negative public health consequences of e-cigarettes, highlighting the need for experimental research, including laboratory studies and clinical trials. Policies should consider potential public health benefits of e-cigarettes, in addition to potential harms.

    Harmful algal blooms can occur when certain types of microscopic algae grow quickly in water, forming visible patches that might harm the health of the environment, plants, or animals. In freshwater, species of Cyanobacteria (also known as bluegreen algae) are the dominant group of harmful, bloom-forming algae. When Cyanobacteria form a harmful algal bloom, potential impairments include restricted recreational activities because of algal scums or algal mats, potential loss of public water supply because of taste and odor compounds (for example, geosmin), and the production of toxins (for example, microcystin) in amounts capable of threatening human health and wildlife.

    Each year more than 600000 women have deaths associated with cigarette smoking. In addition, cigarette smoking is associated with a wide array of morbidities (such as osteoporosis, cardiovascular disease, and adverse pregnancy outcomes). Two hundred million women smoke worldwide, and this number appears to be rising, particularly in developing countries. Obstetrician-gynecologists can play a role in reducing morbidity and mortality from cigarette smoking by educating women about the dangers, advising them not to smoke, and assisting those who do smoke to quit.

    The University of Minnesota Transdisciplinary Tobacco Use Research Center has been examining the multiple dimensions and the scientific evidence required to determine the feasibility of tobacco harm reduction as a means to reduce tobacco-related mortality and morbidity. Because of the complexity associated with exploring this area, an interdisciplinary approach is necessary. The research components that have been of particular focus at our center include (a) developing and validating biomarkers of tobacco-related exposure and toxicity, (b) developing animal models and designing studies with humans to assess a variety of smoking reduction approaches and potential reduced exposure products, and (c) determining individual differences in response to these interventions and products. A description of the ongoing activities and challenges in these areas is provided, along with projected directions for the future. PMID:18067031

    Tobacco smoking is common among people with mental illnesses, and they carry a higher burden of smoking-related illnesses. Despite this, smoke-free policies and systems for supporting cessation have proved difficult to introduce in mental health and drug and alcohol services (MHDAS). This paper examines the barriers to becoming smoke free within New Zealand services. Key informants, including staff, smoke-free coordinators, and cessation specialists were interviewed. Of the 142 invited informants 61 agreed (42%) to participate in a telephone interview, and 56 provided useable data. Organizations had a permissive or transitioning smoking culture, or were smoke free, defined by smoke-free environments, smoke-free-promoting attitudes and behaviours of management and staff, and cessation support. Most organizations were on a continuum between permissive and transitional cultures. Only eight services had a fully smoke-free culture. MHDAS face many challenges in the transition to a smoke-free culture. They are not helped by exemptions in smoke-free policies for mental health services, staff smoking, negative staff attitudes to becoming smoke free, poor knowledge of nicotine dependence, smoking-related harm and comorbidities, and poor knowledge and skills regarding cessation-support options. Health inequalities will continue across both service and socioeconomic divides without a concerted effort to address smoking.

    Tobacco smoking is a growing problem throughout Latin American countries, especially in underdeveloped countries where poverty and lack of education about the dangers of smoking may make people more susceptible to becoming smokers. Moreover, the economies of many Latin American countries have become dependent on the production of tobacco. Furthermore, because of the associated promotion of tobacco, smoking has integrated into many Latin American cultures. Nevertheless, the harmful health effects of tobacco use are well documented, including greatly increased risks of developing chronic obstructive pulmonary disease, cardiovascular disease, and many forms of cancer. The medical costs associated with treating these diseases far outweigh the economic benefits of producing and selling this deadly crop. To control the tobacco pandemic in Latin American countries, nicotine addiction must be recognized and treated as a disease. Governments, both national and local, need to be more involved in enacting anti-smoking policies such as higher tobacco taxation, control of illegal tobacco smuggling, and reimbursement of medical smoking cessation interventions. The training of health professions in the area of nicotine addiction must also be improved, so that they may better assist smokers in their quit attempts and advise patients on, and prescribe, effective smoking cessation pharmacotherapies.

    Tanning for cosmetic purposes by sunbathing or by using artificial tanning devices is widespread. The hazards associated with exposure to ultraviolet radiation are of concern to the medical profession. Depending on the amount and form of the radiation, as well as on the skin type of the individual exposed, ultraviolet radiation causes erythema, sunburn, photodamage (photoaging), photocarcinogenesis, damage to the eyes, alteration of the immune system of the skin, and chemical hypersensitivity. Skin cancers most commonly produced by ultraviolet radiation are basal and squamous cell carcinomas. There also is much circumstantial evidence that the increase in the incidence of cutaneous malignant melanoma during the past half century is related to increased sun exposure, but this has not been proved. Effective and cosmetically acceptable sunscreen preparations have been developed that can do much to prevent or reduce most harmful effects to ultraviolet radiation if they are applied properly and consistently. Other safety measures include (1) minimizing exposure to ultraviolet radiation, (2) being aware of reflective surfaces while in the sun, (3) wearing protective clothing, (4) avoiding use of artificial tanning devices, and (5) protecting infants and children.

    Incarcerated populations across the world have been found to be consistently and significantly more vulnerable to problem gambling than general populations in the same countries. In an effort to gain a more specific understanding of this vulnerability the present study applied latent class analysis and criminal career theory to gambling data collected from a sample of English and Scottish, male and female prisoners (N = 1057). Theoretical links between gambling and crime were tested through three hypotheses: (1) that prisoners in the UK would have higher rates of problem gambling behaviour than the national population; (2) that if the link between gambling and crime is coincidental, gambling behaviour would be highly prevalent in an offending population, and (3) if connections between gambling behaviour and offending are co-symptomatic a mediating factor would show a strong association. The first of these was supported, the second was not supported and the third was partially supported. Latent class analysis found six gambling behaviour clusters measured by responses to the Problem Gambling Severity Index, primarily distinguished by loss chasing behaviour. Longitudinal offending data drawn from the Police National Computer database found four criminal career types, distinguished by frequency and persistence over time. A significant association was found between higher level loss chasing and high rate offending in criminal careers suggesting that impulse control may be a mediating factor for both gambling harm and criminal careers.

    Objectives. We described frequency of secondhand smoke (SHS) exposure among young adults patronizing bars and associations between SHS exposure, attitudes, and smoking behavior. Methods. We collected cross-sectional surveys from randomized time–location samples of bar patrons aged 18 to 26 years in San Diego, California, and Oklahoma City and Tulsa, Oklahoma, in 2010 to 2011. Multivariate logistic regression evaluated associations between SHS exposure, attitudes about dangers of SHS, susceptibility to smoking initiation among nonsmokers, and quit attempts among current smokers. Results. More than 80% of respondents reported past 7-day exposure to any SHS, and more than 70% reported exposure at a bar. Current smokers reported more SHS exposure in cars and their own homes than did nonsmokers. Among nonsmokers, SHS exposure was associated with susceptibility to initiation, but those who believed that SHS exposure is harmful were less susceptible. Belief that SHS is dangerous was associated with quit attempts among smokers. Conclusions. Smoke-free environments and education about the harms of SHS may decrease tobacco use among young adults who frequent bars, where they are heavily exposed to SHS. PMID:24028259

    Background Despite the historically low smoking prevalence among Chinese women, there is a trend of future increase. Purpose We systematically reviewed the correlates of smoking among Chinese girls and women. Method We conducted a systematic review of literature on correlates of smoking among Chinese women using Medline and China Academic Journals databases. Following the PRISMA statement, two investigators independently searched for literature, identified and reviewed papers, assessed the quality of the papers, and extracted information. The characteristics of studies and correlates of smoking were synthesized separately for youth and adults. Results A total of 15 articles (11 on adults, 4 on youth) met the inclusion criteria. Based on these studies, peer smoking was the most consistent correlate of smoking among Chinese girls. Among Chinese women, partner smoking, job-related stress, and exposure to cigarettes made for women were consistent correlates of smoking. Knowledge of harms and negative attitudes towards smoking were found to be negatively associated with smoking. Conclusion Overall, the evidence base for smoking among Chinese women is limited. Although smoking among Chinese women is still at an early stage, it is becoming more prevalent among specific population subgroups, such as rural-to-urban migrant workers. Although further research is needed, findings from the current study provide a roadmap for research and policy on prevention of smoking among Chinese girls and women. PMID:24222041

    The 2003 School Health Act of Taiwan stipulated that school campuses of senior high and below should be smoke free, but data from the Global Youth Tobacco Survey show that the majority of students are exposed to smoke in public and at home. More than 50% of nonsmokers indicated that they had been exposed to secondhand smoke (SHS) in public places, with the exposure rate as high as 90% among smokers. More than 40% of junior and senior high school students were exposed to SHS at home. Support for banning smoking in public places ranged from almost 60% to almost 80%. More than 60% of current smokers and almost 90% of never smokers think that smoke from others is harmful to them. With a clear body of evidence detailing the harmful effects, reduction and eventual elimination of exposure to SHS should be the goal of the tobacco control community.

    This study investigated behavioral and sociodemographic factors associated with tobacco use among female university students patronizing water pipe cafes in Cairo, Egypt. We interviewed two groups of female university student smokers (100 and 96 students from a public and a private university, respectively). The interviews took place in nine water pipe cafes near the two universities. A logistic regression model was developed to analyze the relationship between tobacco-related knowledge and beliefs and the choice between smoking water pipe or cigarettes. Among these smokers, 27% smoked cigarettes only, 37.8% smoked water pipe only, and 35.2% smoked both types of tobacco. Most of the water pipe smokers (74.1%) preferred this method because they believe it to be less harmful than smoking cigarettes. More than half of the subjects were encouraged to start smoking by other females (56.6%). Curiosity was a significant factor for initiation (OR = 2.8, 95% CI = 1.3-6.2, p<.01). We found no significant differences between water pipe and cigarette smokers regarding current age, age at initiation, quit attempts, knowledge about the hazards of smoking, wanting to be fashionable, or smoking with friends. About one in four (23.7%) attempted to quit, with health cited as a major reason. An urgent need exists for correction of the misperception among this study population that water pipe smoking is safe and less harmful than cigarette smoking.

    This study examines the extent of tobacco advertising and the coverage of smoking and health in all Irish produced women's magazines for 1989-93. There were 805 pieces in 402 magazines of which 684 (85%) were tobacco advertisements, 48 (5.7%) were new briefs; 27 (3.4%) were advice columns; 16 (2%) were feature articles; 15 (1.9%) were health promotion advertisements dealing with smoking and pregnancy; 10 (1.2%) were letters and 5 (0.61%) were editorials. Topics covered by the 106 articles on smoking were: smoking cessation-43 (40.6%); general health issues 35 (33%); smoking in pregnancy-4 (3.8%) and passive smoking 17 (16%). Of the 106 articles, 4 were negative about measures to control smoking. Four cigarette brands accounted for 70% of the advertisements. No tobacco advertisement carried the warning that "Smoking when pregnant harms your baby" or "Smoking kills". The 385002 cm2 of space devoted to tobacco advertising and negative messages about the dangers of tobacco and health represents 1.95% of total magazine space and is 14.5 times greater than the 26575 cm2 of positive messages about the dangers of smoking. That these magazines advertise tobacco without adequately covering the harmful effects of tobacco would suggest a degree of hypocrisy in their stated concern for women's health and lends further strength to the principle of a total ban on all tobacco advertising.

  16. In Situ Derivatization and Quantification of Seven Carbonyls in Cigarette Mainstream Smoke.

    Carbonyls, especially aldehydes, are a group of harmful volatile organic compounds that are found in tobacco smoke. Seven carbonyls are listed on the FDA's harmful and potential harmful constituents list for tobacco or tobacco smoke. Carbonyls have reactive functional groups and thus are challenging to quantitatively measure in cigarette smoke. The traditional method of measuring carbonyls in smoke involves solvent-filled impinger trapping and derivatization. This procedure is labor-intensive and generates significant volumes of hazardous waste. We have developed a new method to efficiently derivatize and trap carbonyls from mainstream smoke in situ on Cambridge filter pads. The derivatized carbonyls are extracted from the pads and subsequently quantified by ultra-high-pressure liquid chromatography coupled with tandem mass spectrometry. The new method has been validated and applied to research and commercial cigarettes. Carbonyl yields from research cigarettes are comparable to those from other published literature data. With a convenient smoke collection apparatus, a 4 min sample analysis time, and a low- or submicrogram detection limit, this new method not only simplifies and speeds the detection of an important class of chemical constituents in mainstream smoke but also reduces reactive losses and provides a more accurate assessment of carbonyl levels in smoke. Excellent accuracy (average 98%) and precision (14% average relative standard deviation in research cigarettes) ensure this new method's sufficient fidelity to characterize conventional combusted tobacco products, with potential application toward new or emerging products.

    2015-04-01

    Waterpipe (WP) smoking is growing as an alternative to cigarette smoking, especially in younger age groups. E-cigarette use has also increased in recent years. A majority of smokers mistakenly believe that WP smoking is a social entertainment practice that leads to more social behavior and relaxation and that this type of smoking is safe or less harmful and less addictive than cigarette smoking. In reality, WP smokers are exposed to hundreds of toxic substances that include known carcinogens. High exposures to carbon monoxide and nicotine are major health threats. Persons exposed to secondhand WP smoke are also at risk. There is growing evidence that WP smoke causes adverse effects on the pulmonary and cardiovascular systems and is responsible for cancer. E-cigarettes are marketed as a smokeless and safe way to inhale nicotine without being exposed to the many toxic components of tobacco cigarettes, and as an aid to smoking cessation. In fact, consumers (vapers) and secondhand vapers can be exposed to substantial amounts of VOC, PAH or other potentially harmful substances. Of major health concern is the inhalation of fine and ultrafine particles formed from supersaturated 1,2-propanediol vapor. Such particles can be deposited in the deeper parts of the lung and may harm the respiratory system or increase the risk of acquiring asthma. More research on the safety of e-cigarettes needs to be conducted to ensure a high level of public health protection in the long-term.

    2014-01-01

    A carefully structured Tobacco Harm Reduction (THR) initiative, with e-cigarettes as a prominent THR modality, added to current tobacco control programming, is the most feasible policy option likely to substantially reduce tobacco-attributable illness and death in the United States over the next 20 years. E-cigarettes and related vapor products are the most promising harm reduction modalities because of their acceptability to smokers. There are about 46 million smokers in the United States, and an estimated 480,000 deaths per year attributed to cigarette smoking. These numbers have been essentially stable since 2004. Currently recommended pharmaceutical smoking cessation protocols fail in about 90% of smokers who use them as directed, even under the best of study conditions, when results are measured at six to twelve months. E-cigarettes have not been attractive to non-smoking teens or adults. Limited numbers non-smokers have experimented with them, but hardly any have continued their use. The vast majority of e-cigarette use is by current smokers using them to cut down or quit cigarettes. E-cigarettes, even when used in no-smoking areas, pose no discernable risk to bystanders. Finally, addition of a THR component to current tobacco control programming will likely reduce costs by reducing the need for counseling and drugs. PMID:25003176

    Inhalation of tobacco smoke aerosol is a two-step process involving puffing followed by inhalation. Measured smoke deposition efficiencies in the lung (20-70%) are greater than expected for smoke particles of 150 -- 250 nm count median diameter (CMD). Various mechanisms have been put forward to explain this enhanced deposition pattern, including coagulation, hygroscopic growth, condensation and evaporation, changes in composition, or changes in inhalation behaviour. This paper represents one of a series of studies seeking to better quantify smoke chemistry, inhalation behaviour and cumulative particle growth. The studies have been conducted to better understand smoke dosimetry and links to disease as part of a wider programme defining risk and potential harm reduction. In this study, the average CMD of inhaled smoke was 160 nm while the average CMD of exhaled smoke was 239 nm with an average growth factor of 1.5.

    This paper presents the results of a survey carried out among those attending the Saldent 2006 conference. The questionnaire used for this purpose included questions concerning smoking among dentists, permission to smoke in the dental surgery, patients motivation to quit smoking, knowledge regarding the harmful effect of smoking on the oral cavity and the possible need for teaching preventive measures on the subject during under- and postgraduate education. The results showed that when compared with those obtained 6 years ago smoking among the dentists has declined. Answers to the questions concerning the influence of smoking on oral cavity showed a high awareness of this danger among the questionnaire respondents. Also the high number of dentists who are motivating patients against smoking confirms the opinion that in the planning of antismoking programs dentists can play a significant role.

    2016-12-12

    The aim of the present study was to determine the perception of 10 anti-smoking advertisements in 1434 Turkish adolescents. We used the Effectiveness of the Anti-smoking Advertisements Scale, which included 6 items for each advertisement; each item was assessed on a 5-point Likert-type scale. Multiple logistic regression analysis was used to determine the factors associated with the impact of the advertisements. All the advertisements were more effective for adolescents who had never smoked compared to ex-smokers and current smokers. We also noted that, regardless of age, smoking status decreased the effectiveness of all the advertisements. Previous studies have shown that smokers have a negative attitude towards anti-smoking messages. In the present study, the most effective advertisements among adolescents were those with "Sponge and tar", "Smoking harms in every breath" and "Children want to grow". In conclusion, although anti-smoking campaigns are targeted towards adults, they also have a strong influence on adolescents. The main target population for advertisements should be individuals aged < 15 years who have not yet started smoking.

    Recently Mexico passed federal and state-level laws banning smoking in indoor spaces. These actions are totally in accordance with measures proposed in the WHO-FCTCs article 8, ratified by Mexico in 2004. This essay reviews scientific evidence that secondhand smoke causes both chronic and acute diseases among non smokers, children and adults. There is no safe level of exposure to secondhand smoke, so the only effective intervention to protect Mexican people from such harmful exposure is by promoting 100% smoke free indoor air, as the two new laws do. Total banning of smoking is associated with reduction in smoking prevalence, amount of cigarette smoked per day, and an increase in cessation rates. Reductions in acute respiratory symptoms and hospitalization of acute myocardial infarction have been also reported. Well documented examples show that main tobacco industry arguments against smoke free policy: negative economic impact and lack of support from the public, are unjustified. These two laws strengthen the Mexican tobacco control program. Next steps include their implementation, evaluation, enforcement of compliance and encouragement for similar laws at state level.

  16. Microbiological components in mainstream and sidestream cigarette smoke

    PubMed Central

    2012-01-01

    Background Research has shown that tobacco smoke contains substances of microbiological origin such as ergosterol (a fungal membrane lipid) and lipopolysaccharide (LPS) (in the outer membrane of Gram-negative bacteria). The aim of the present study was to compare the amounts of ergosterol and LPS in the tobacco and mainstream (MS) and sidestream (SS) smoke of some popular US cigarettes. Methods We measured LPS 3-hydroxy fatty acids and fungal biomass biomarker ergosterol in the tobacco and smoke from cigarettes of 11 popular brands purchased in the US. University of Kentucky reference cigarettes were also included for comparison. Results The cigarette tobacco of the different brands contained 6.88-16.17 (mean 10.64) pmol LPS and 8.27-21.00 (mean 14.05) ng ergosterol/mg. There was a direct correlation between the amounts of ergosterol and LPS in cigarette tobacco and in MS smoke collected using continuous suction; the MS smoke contained 3.65-8.23% (ergosterol) and 10.02-20.13% (LPS) of the amounts in the tobacco. Corresponding percentages were 0.30-0.82% (ergosterol) and 0.42-1.10% (LPS) for SS smoke collected without any ongoing suction, and 2.18% and 2.56% for MS smoke collected from eight two-second puffs. Conclusions Tobacco smoke is a bioaerosol likely to contain a wide range of potentially harmful bacterial and fungal components. PMID:22898193

  17. Disproportionate organizational injustice: a close look at facilities exempted from indoor smoking laws in Canada.

    Federal and provincial legislation bans smoking in indoor public spaces and workplaces, yet exemptions exist for residential facilities such as nursing homes and addiction treatment centres. In relying on ventilated smoking rooms, however, these organizations are failing to protect the health of their employees and clients. Increased use of risk messages regarding the harms of second- and third-hand smoke, together with enhanced nicotine replacement therapies for smokers, would rectify this disproportionate injustice. Such an approach must also recognize and counteract the efforts of the tobacco industry to block total indoor smoking bans.

    This cross sectional survey was conducted to determine the support in making Penang UNESCO World Heritage Site (GTWHS) smoke free and to determine the influence of tolerance towards smoking on this support. This is the first phase in making Penang, Malaysia a smoke free state. A multistage sampling process was done to select a sample of respondents to represent the population of GTWHS. Attitude towards smoking was assessed using tolerance as a proxy. A total of 3,268 members of the community participated in the survey. A big majority (n = 2969; 90.9%) of the respondents supported the initiative. Support was lowest among the owners and residents/tenants, higher age groups, the Chinese, men, respondents who had poor knowledge of the places gazetted as smoke free, and respondents with poor knowledge of the health effects on smokers and on passive smokers. The odds (both adjusted and unadjusted) of not supporting the initiative was high among those tolerant to smoking in public areas. Tolerance towards smoking was associated with 80.3% risk of non-support in the respondents who were tolerant to smoking and a 57.2% risk in the population. Health promotion and education concerning the harm of tobacco smoke in Malaysia, which has mainly targeted smokers, must change. Health education concerning the risks of second hand smoke must also be given to non-smokers and efforts should be made to denormalize smoking. PMID:25338116

    It is obvious that smoking is harmful. It is especially dramatic that it may cause a lot of dysfunctions among newborns who without their free will are expose to toxic tobacco components. The consequences are as serious when mother smoke as when she is exposed to environmental tobacco smoke (ETS). Exposure to cigarette smoke during pregnancy is directly correlated to premature rupture of the membranes, premature birth, intrauterine growth retardatyion--IURG, low birth weight, smaller body length of newborn, reduced lung function--hypoxia, delayed development of respiratory and nervous system, sudden infant death syndrome--SIDS, obesity, allergy, arterial hypertension or even tumors. That is why the prophylactic of above illnesses is important since first days of life.

    Electronic cigarettes (e-cigarettes) are vaporisers of liquids often containing nicotine. In the inhaled aerosol carcinogens, ultrafine and metal particles are detected usually in concentrations below those measured in tobacco smoke. Therefore, these products are expected to be less harmful. This has not yet been proven. The long-term safety of e-cigarettes is unknown. Short duration use leads to airway irritation and increased diastolic blood pressure. So far only two randomised controlled trials have investigated efficacy and safety of e-cigarettes for smoking cessation: No clear advantage was shown in comparison to smoking cessation medication. Due to insufficient evidence, e-cigarettes cannot be recommended for smoking cessation. Problematic are the lack of regulation and standardisation of e-cigarette products, which makes general conclusions impossible.

    Tobacco discouragement, smoking cessation and tobacco endgame policies are sometimes criticised for being unduly paternalistic: governments should respect citizens' freedom and not take over their individual responsibility for healthy behaviour. In this commentary, I argue that very strict tobacco policies can be justified on multiple grounds, including the harm principle, the public good of maintaining a healthy society, and the reduction of health inequities. The moral reasons governments have to protect people against the harms of smoking do not limit or infringe upon the responsibility of each individual to take care of her own health: responsibility for healthy behaviour is not a zero-sum game.

    Cigarette smoking is associated with numerous diseases and poses a serious challenge to the current healthcare system worldwide. Smoking impacts both innate and adaptive immunity and plays dual roles in regulating immunity by either exacerbation of pathogenic immune responses or attenuation of defensive immunity. Adaptive immune cells affected by smoking mainly include T helper cells (Th1/Th2/Th17), CD4+CD25+ regulatory T cells, CD8+ T cells, B cells and memory T/B lymphocytes while innate immune cells impacted by smoking are mostly DCs, macrophages and NK cells. Complex roles of cigarette smoke have resulted in numerous diseases, including cardiovascular, respiratory and autoimmune diseases, allergies, cancers and transplant rejection etc. Although previous reviews have described the effects of smoking on various diseases and regional immunity associated with specific diseases, a comprehensive and updated review is rarely seen to demonstrate impacts of smoking on general immunity and, especially on major components of immune cells. Here, we aim to systematically and objectively review the influence of smoking on major components of both innate and adaptive immune cells, and summarize cellular and molecular mechanisms underlying effects of cigarette smoking on the immune system. The molecular pathways impacted by cigarette smoking involve NFκB, MAP kinases and histone modification. Further investigations are warranted to understand the exact mechanisms responsible for smoking-mediated immunopathology and to answer lingering questions over why cigarette smoking is always harmful rather than beneficial even though it exerts dual effects on immune responses.

    Drug use is a public health problem associated with high mortality and morbidity, and is often accompanied by suboptimal engagement in health care. Harm reduction is a pragmatic public health approach encompassing all goals of public health: improving health, social well-being, and quality of life. Harm reduction prioritizes improving the lives of people who use drugs in partnership with those served without a narrow focus on abstinence from drugs. Evidence has shown that harm reduction oriented practice can reduce transmission of blood-borne illnesses, and other injection related infections, as well as preventing fatal overdose.

    European literature contains fictional descriptions of self-harm and self-punishment over a time span of almost 2 500 years. This article presents such descriptions, from Sofocles' tragedy about King Oedipus to contemporary literature. Particular interest is dedicated to the Austrian Nobel prize laureate Elfriede Jelinek and the Norwegian author Karl Ove Knausgård. In Jelinek's fictional universe, self-harm is particularly related to the topic of autonomy in a family context; while Knausgård describes the role of shame in triggering and sustaining self-harming behaviour.

  5. Worldwide effort against smoking.

    PubMed

    1986-07-01

    The 39th World Health Assembly, which met in May 1986, recognized the escalating health problem of smoking-related diseases and affirmed that tobacco smoking and its use in other forms are incompatible with the attainment of "Health for All by the Year 2000." If properly implemented, antismoking campaigns can decrease the prevalence of smoking. Nations as a whole must work toward changing smoking habits, and governments must support these efforts by officially stating their stand against smoking. Over 60 countries have introduced legislation affecting smoking. The variety of policies range from adopting a health education program designed to increase peoples' awareness of its dangers to increasing taxes to deter smoking by increasing tobacco prices. Each country must adopt an antismoking campaign which works most effectively within the cultural parameters of the society. Other smoking policies include: printed warnings on cigarette packages; health messages via radio, television, mobile teams, pamphlets, health workers, clinic walls, and newspapers; prohibition of smoking in public areas and transportation; prohibition of all advertisement of cigarettes and tobacco; and the establishment of upper limits of tar and nicotine content in cigarettes. The tobacco industry spends about $2000 million annually on worldwide advertising. According to the World Health Organization (WHO), controlling this overabundance of tobacco advertisements is a major priority in preventing the spread of smoking. Cigarette and tobacco advertising can be controlled to varying degrees, e.g., over a dozen countries have enacted a total ban on advertising on television or radio, a mandatory health warning must accompany advertisements in other countries, and tobacco companies often are prohibited from sponsoring sports events. Imposing a substantial tax on cigarettes is one of the most effective means to deter smoking. However, raising taxes and banning advertisements is not enough because

    Public health officials and leaders of 168 nations have signaled their concern regarding the health and economic impacts of smoking by becoming signatory parties to the World Health Organization Framework Convention on Tobacco Control (FCTC). One of FCTC’s purposes is to help achieve meaningful regulation for tobacco products in order to decrease the exposure to harmful and potentially harmful constituents (HPHCs) delivered to users and those who are exposed to secondhand smoke. Determining baseline delivery ranges for HPHCs in modern commercial tobacco products is crucial information regulators could use to make informed decisions. Establishing mainstream smoke delivery concentration ranges for toxic metals was conducted through analyses of total particulate matter (TPM) collected with smoking machines using standard smoking regimens. We developed a rapid analytical method with microwave digestion of TPM samples obtained with smoking machines using electrostatic precipitation under the ISO and Intense smoking regimens. Digested samples are analyzed for chromium, manganese, cobalt, nickel, arsenic, cadmium, and lead using inductively coupled plasma-mass spectrometry. This method provides data obtained using the ISO smoking regimen for comparability with previous studies as well as an Intense smoking regimen that represents deliveries that fall within the range of human exposure levels to toxic metals.

    Exposure to secondhand smoke (SHS) harms all children's health, especially children with asthma. Yet, children with asthma are as likely to live with smokers as healthy children. Household smoking bans are being advocated to reduce children's harm from SHS. To measure the effect of household smoking bans on child SHS exposure and to examine correlates of strict smoking bans in a low-income, diverse sample, 91 children with asthma were matched to 91 healthy children. All had at least one smoker living in their homes. Nicotine dosimeters, child cotinine assays, and maternal reports quantified child SHS exposures. Maternal reports of household smoking rules, behaviors, and beliefs, and other family characteristics were also gathered. The presence of a strict household smoking ban vastly reduced children's SHS exposures and was associated with fewer cigarettes smoked by the mother and by other family members, the belief that SHS was a personal health risk, having children with asthma, and living in a single-family home. Many children are exposed to high levels of SHS at home. Strict household smoking bans greatly decrease, but do not eliminate children's SHS exposure. Even in disadvantaged families, mutable factors were associated with strict smoking bans. Increased dissemination and use of established public health strategies are needed to reduce children's SHS exposures.

    2005-01-01

    The oviduct is an exquisitely designed organ that functions in picking-up ovulated oocytes, transporting gametes in opposite directions to the site of fertilization, providing a suitable environment for fertilization and early development, and transporting preimplantation embryos to the uterus. A variety of biological processes can be studied in oviducts making them an excellent model for toxicological studies. This review considers the role of the oviduct in oocyte pick-up and embryo transport and the evidence that chemicals in both mainstream and sidestream cigarette smoke impair these oviductal functions. Epidemiological data have repeatedly shown that women who smoke are at increased risk for a variety of reproductive problems, including ectopic pregnancy, delay to conception, and infertility. In vivo and in vitro studies indicate the oviduct is targeted by smoke components in a manner that could explain some of the epidemiological data. Comparisons between the toxicity of smoke from different types of cigarettes, including harm reduction cigarettes, are discussed, and the chemicals in smoke that impair oviductal functioning are reviewed.

    Objective To offer preliminary guidance on prescribing smoked cannabis for chronic pain before the release of formal guidelines. Quality of evidence We reviewed the literature on the analgesic effectiveness of smoked cannabis and the harms of medical and recreational cannabis use. We developed recommendations on indications, contraindications, precautions, and dosing of smoked cannabis, and categorized the recommendations based on levels of evidence. Evidence is mostly level II (well conducted observational studies) and III (expert opinion). Main message Smoked cannabis might be indicated for patients with severe neuropathic pain conditions who have not responded to adequate trials of pharmaceutical cannabinoids and standard analgesics (level II evidence). Smoked cannabis is contraindicated in patients who are 25 years of age or younger (level II evidence); who have a current, past, or strong family history of psychosis (level II evidence); who have a current or past cannabis use disorder (level III evidence); who have a current substance use disorder (level III evidence); who have cardiovascular or respiratory disease (level III evidence); or who are pregnant or planning to become pregnant (level II evidence). It should be used with caution in patients who smoke tobacco (level II evidence), who are at increased risk of cardiovascular disease (level III evidence), who have anxiety or mood disorders (level II evidence), or who are taking higher doses of opioids or benzodiazepines (level III evidence). Cannabis users should be advised not to drive for at least 3 to 4 hours after smoking, for at least 6 hours after oral ingestion, and for at least 8 hours if they experience a subjective “high” (level II evidence). The maximum recommended dose is 1 inhalation 4 times per day (approximately 400 mg per day) of dried cannabis containing 9% delta-9-tetrahydrocannabinol (level III evidence). Physicians should avoid referring patients to “cannabinoid” clinics (level

    Background: Cigarette smoking is the largest preventable cause of death worldwide. No systematic review is available on the situation of the smoking in Iran, so we decided to provide an overview of the studies in the field of smoking in Iranian populations. Methods: Published Persian-language papers of all types until 2009 indexed in the IranMedex (http://www.iranmedex.com) and Magiran (http://www.magiran.com). Reports of World Health Organization were also searched and optionally employed. The studies concerning passive smoking or presenting the statistically insignificant side effects were excluded. Databases were searched using various combinations of the following terms: cigarette, smoking, smoking cessation, prevalence, history, side effects, and lung cancer by independent reviewers. All the 83 articles concerning the prevalence or side effects of the smoking habit in any Iranian population were selected. The prevalence rate of daily cigarette smoking and the 95% confidence interval as well as smoking health risk associated odds ratio (OR) were retrieved from the articles or calculated. Results: The reported prevalence rates of the included studies, the summary of smoking-related side effects and the ORs (95%CI) of smoking associated risks and the available data on smoking cessation in Iran have been shown in the article. Conclusion: Because of lack of certain data, special studies on local pattern of tobacco use in different districts, about the relationship between tobacco use and other diseases, especially non communicable diseases, and besides extension of smoking cessation strategies, studies on efficacy of these methods seems to be essential in this field.

    2012-06-23

    Self-harm and suicide are major public health problems in adolescents, with rates of self-harm being high in the teenage years and suicide being the second most common cause of death in young people worldwide. Important contributors to self-harm and suicide include genetic vulnerability and psychiatric, psychological, familial, social, and cultural factors. The effects of media and contagion are also important, with the internet having an important contemporary role. Prevention of self-harm and suicide needs both universal measures aimed at young people in general and targeted initiatives focused on high-risk groups. There is little evidence of effectiveness of either psychosocial or pharmacological treatment, with particular controversy surrounding the usefulness of antidepressants. Restriction of access to means for suicide is important. Major challenges include the development of greater understanding of the factors that contribute to self-harm and suicide in young people, especially mechanisms underlying contagion and the effect of new media. The identification of successful prevention initiatives aimed at young people and those at especially high risk, and the establishment of effective treatments for those who self-harm, are paramount needs.

Results from structured interviews showed that 83 (16.1%) participants reported self-harming in the previous 6 months, and this was more common among those serving custodial sentences than those serving CBOs (19.4% vs. 12.4%; OR 3.10, 95% CI: 1.74-5.55). Multiple incidents were more common in females and 24% (95% CI: 19-39) of participants who had self-harmed reported having done so with suicidal intent. Self-harm was associated with recent bullying victimization, expulsion from school, past year violent victimization, cannabis dependence, and risk-taking behavior in the preceding year. The epidemiological profile of self-harm in this population appears to be distinct from that seen in the general population. Young offenders who self-harm are a vulnerable group with high rates of psychiatric morbidity, substance misuse problems, and social risk factors. They may benefit from targeted psychological interventions designed specifically to address impulsivity, delivered both within-and during the transition from-the youth justice system.

    The level of knowledge in the society about the harmful influence of smoking is increasing systematically. But there are still many people ignoring the warnings and prohibitions concerning smoking. The results of the research show that it is highly worrying that there are people for whom smoking is incredibly dangerous, e.g. children, youth, women, especially pregnant women. The aim of the work was to establish the percentage of smoking women among the patients of the women health centre, with the special focus on pregnant women. There were 120 women encompassed in this study in the health centre in Opoczno and 120 women using a similar health centre in Lodz between the 1st and the 15th March 2007, using a auditoria survey questionnaire. The collected data was worked out statistically. In the group of 240 tested people, 87 admitted to smoking, which is 36.3% of the respondents. Among the 185 women who were not pregnant, but were smoking, there were 75 (40.5%) and in the group of 55 pregnant women, there were 12 who smoked (f=0.22). Over 22% of the smoking women smoked over 10 cigarettes a day. From among 87 of the surveyed, 35.6% claimed they smoked everywhere they wanted. Majority of the respondents that is 52.9% lived with at least one other smoking person. Over 70% of them would like to quit smoking. Almost 48% stated their doctor has never talked with them about the influence of smoking on their health and almost 42% stated that no nurse or midwife has ever talked to them about this subject. Frequency of smoking among the tested people who were using the women health centre was high. Especially worrying was the percentage of the smoking pregnant women--every fifth of them smoked.

    A multi-centre enquiry in 12 of 30 provinces of Burkina Faso was carried out to study smoking in pupils at secondary schools. The prevalence of smoking was 13.6 per cent. Amongst the smokers, occasional smoking was the most common, involving 62 per cent. Boys smoked more than girls. The average age of starting smoking was early, at 13.4 years. The majority of smokers consumed less than five cigarettes a day and the favourite place for consumption was the home of their parents or guardian and at school. The determinants of school smokers were above all environmental: the influence of friends and advertising. The students showed a good knowledge of the harmful effects of smoking. This knowledge was linked to their educational level and to their status as a smoker or non-smoker. The proportion of pupils who had obtained good results in the term which preceded the enquiry was more significant amongst the non-smokers than amongst the smokers. An awareness of the significance of smoking amongst pupils by their parents, guardians and teachers involves health education and rigorous legislative measures on advertising and these would contribute to some reduction in the extent of the phenomenon in educational establishments.

    BACKGROUND Waterpipe tobacco smoking prevalence, practice, and the associated health perceptions among dental practitioners have not been previously reported. This study aims to determine the prevalence of waterpipe smoking among dental practitioners and to evaluate their awareness of health hazards of waterpipe smoking, particularly the adverse effects on oral health. METHODS This was a cross-sectional questionnaire-based survey among dental practitioners. Surveyed dental practitioners practiced dentistry in the holy city of Al-Madinah Al-Munawarah, a city in the Central-Western Region of Saudi Arabia, and the study was conducted during March 2015. The questionnaire consisted of questions on demographic data, history and practices of tobacco use, and perceptions toward the health hazards of smoking. Dentists were approached at their work places and invited to participate. Descriptive statistics were used to describe the sample’s demographic and smoking characteristics, while cross-tabulation and chi-square test were used to determine the statistical significance of association between the groups (P ≤ 0.05). RESULTS One hundred dental practitioners participated in the survey, with 55 males and 45 females. Twenty-six percent indicated that they were waterpipe smokers. Male gender and cigarette smoking were the only factors to be significantly associated with waterpipe smoking (P = 0.008 and P = 0.000, respectively). Most participants stated that waterpipe smoking is harmful to health, and the most commonly reported health hazard was respiratory disease, which was reported by 81% of participants. CONCLUSIONS Prevalence of waterpipe smoking among dental practitioners is comparable to adult populations but lower than younger populations of university students. Health awareness of dental practitioners regarding waterpipe smoking was judged to be insufficient. PMID:27695374

    Repace, J

    2004-01-01

    Objective: To assess the contribution of secondhand smoke (SHS) to aircraft cabin air pollution and flight attendants' SHS exposure relative to the general population. Methods: Published air quality measurements, modelling studies, and dosimetry studies were reviewed, analysed, and generalised. Results: Flight attendants reported suffering greatly from SHS pollution on aircraft. Both government and airline sponsored studies concluded that SHS created an air pollution problem in aircraft cabins, while tobacco industry sponsored studies yielding similar data concluded that ventilation controlled SHS, and that SHS pollution levels were low. Between the time that non-smoking sections were established on US carriers in 1973, and the two hour US smoking ban in 1988, commercial aircraft ventilation rates had declined three times as fast as smoking prevalence. The aircraft cabin provided the least volume and lowest ventilation rate per smoker of any social venue, including stand up bars and smoking lounges, and afforded an abnormal respiratory environment. Personal monitors showed little difference in SHS exposures between flight attendants assigned to smoking sections and those assigned to non-smoking sections of aircraft cabins. Conclusions: In-flight air quality measurements in ~250 aircraft, generalised by models, indicate that when smoking was permitted aloft, 95% of the harmful respirable suspended particle (RSP) air pollution in the smoking sections and 85% of that in the non-smoking sections of aircraft cabins was caused by SHS. Typical levels of SHS-RSP on aircraft violated current (PM2.5) federal air quality standards ~threefold for flight attendants, and exceeded SHS irritation thresholds by 10 to 100 times. From cotinine dosimetry, SHS exposure of typical flight attendants in aircraft cabins is estimated to have been >6-fold that of the average US worker and ~14-fold that of the average person. Thus, ventilation systems massively failed to control SHS air

    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

    Inhalation of tobacco smoke aerosol is a two-step process involving puffing followed by inhalation. Measured smoke deposition efficiencies in the lung (20-70%) are greater than expected for smoke particles of diameter 150 -- 250 nm CMD. Various mechanisms have been put forward to explain this enhanced deposition pattern, including coagulation, hygroscopic growth, condensation and evaporation, changes in composition, or changes in inhalation behaviour. This paper represents one of a series of studies seeking to better quantify smoke chemistry, inhalation behaviour and cumulative particle growth. The studies have been conducted to better understand smoke dosimetry and links to disease as part of a wider programme defining risk and potential harm reduction. In this study, it was noted that particle deposition increased with increasing inhalation depth, and that smoke inhalation volumes were generally greater than normal tidal breathing volumes. A weak association was observed between particle diameter and puff flow, but no strong association between particle diameter and retention efficiency.

    Objectives. Because household smoking levels and adoption of domestic smoking rules may be endogenously related, we estimated a nonrecursive regression model to determine the simultaneous relationship between home smoking restrictions and household smoking. Methods. We used data from a May–June 2012 survey of Philadelphia, Pennsylvania, households with smokers (n = 456) to determine the simultaneous association between smoking levels in the home and the presence of home restrictions on smoking. Results. We found that home smoking rules predicted smoking in the home but smoking in the home had no effect on home smoking restrictions. Conclusions. Absent in-home randomized experiments, a quasi-experimental causal inference suggesting that home smoking rules result in lower home smoking levels may be plausible. PMID:24524533

    BACKGROUND Smoking is a serious risk to health globally. Health care professionals play a key role in the prevention of smoking as they are considered a role model by patients. OBJECTIVES The aims of this study are to evaluate smoking rate among physicians and dentists from Sulaymaniyah, Iraqi Kurdistan, Iraq, and to understand their knowledge and attitudes toward tobacco smoking. METHODS A cross-sectional web-based survey was conducted involving physicians and dentists working in both University of Sulaimani and Sulaymaniyah Teaching Hospitals. A questionnaire created based on World Health Organization Global Health Professional Survey with slight modifications was emailed to the study participants and the responses received were analyzed. RESULTS Incidence of smoking among physicians and dentists was 26.5%, with a significantly higher rate among male compared to female health care professionals. The mean age of starting smoking was 22.3 (±4.8) years. Only 7.3% of health care professionals received formal training on smoking cessation. All responders agreed that smoking is harmful to health. However, ever smokers compared to never smokers were less likely to agree that health care professionals should set a positive impact by not smoking. CONCLUSION Smoking rate is high among physicians and dentists from Sulaymaniyah city/Iraq, and at the same time, there is a low rate of training on smoking cessation. PMID:26966391

    Although both low socioeconomic status and cigarette smoking increase health problems and mortality, their possible combined or interactive influence is less clear On one hand, the health of low status groups may be harmed least by unhealthy behavior such as smoking because, given the substantial health risks produced by limited resources, they have less to lose from damaging lifestyles. On the other hand, the health of low status groups may be harmed most by smoking because lifestyle choices exacerbate the health problems created by deprived material conditions. Alternatively, the harm of low status and smoking may accumulate additively rather than multiplicatively. We test these arguments with data from the 1990 U.S. National Health Interview Survey, and with measures of morbidity and mortality. For ascribed statuses such as gender, race, and ethnicity, and for the outcome measure of mortality, the results favor the additive argument, whereas for achieved status and morbidity, the results support the vulnerability hypothesis--that smoking inflicts greater harm among disadvantaged groups.

    Objective This study assessed whether smoking in the movies was associated with smoking in young adults. Methods A national web-enabled cross-sectional survey of 1528 young adults, aged 18–25, was performed between September and November 2005. Logistic regression and path analysis using probit regression were used to assess relationships between exposure to smoking in the movies and smoking behavior. Analysis was completed in December 2006. Results Exposure to smoking in the movies predicted current smoking. The adjusted odds of current smoking increased by a factor of 1.21 for each quartile increase in exposure to smoking (p<0.01) in the movies, reaching 1.77 for the top exposure quartile. The unadjusted odds of established smoking (100+ cigarettes with current smoking) increased by 1.23 per quartile (p<0.001) of exposure, reaching 1.86 for the top quartile. This effect on established smoking was mediated by two factors related to smoking in the movies: positive expectations about smoking and exposure to friends and relatives who smoked, with positive expectations accounting for about two thirds of the effect. Conclusions The association between smoking in the movies and young adult smoking behavior exhibited a dose–response relationship; the more a young adult was exposed to smoking in the movies, the more likely he or she would have smoked in the past 30 days or have become an established smoker.

  11. Is human existence worth its consequent harm?

    PubMed Central

    Doyal, Len

    2007-01-01

    Benatar argues that it is better never to have been born because of the harms always associated with human existence. Non‐existence entails no harm, along with no experience of the absence of any benefits that existence might offer. Therefore, he maintains that procreation is morally irresponsible, along with the use of reproductive technology to have children. Women should seek termination if they become pregnant and it would be better for potential future generations if humans become extinct as soon as humanely possible. These views are challenged by the argument that while decisions not to procreate may be rational on the grounds of the harm that might occur, it may equally rational to gamble under certain circumstances that future children would be better‐off experiencing the harms and benefits of life rather than never having the opportunity of experiencing anything. To the degree that Benatar's arguments preclude the potential rationality of any such gamble, their moral relevance to concrete issues concerning human reproduction is weakened. However, he is right to emphasise the importance of foreseen harm when decisions are made to attempt to have children. PMID:17906053

    The relation of personality to disability in old age is not well understood. The authors examined the relation of harm avoidance, a trait indicating a tendency to worry, fear uncertainty, be shy, and tire easily, to disability in a group of 474 older persons without dementia. Participants completed the 35-item Harm Avoidance scale. Disability was assessed with the Rosow-Breslau scale, a self-report measure of physical mobility. Performance-based tests of lower limb functions were also administered from which composite measures of gait, balance, and strength were derived. In a logistic regression model controlled for age, sex, education, and lower limb function, persons with high levels of harm avoidance were nearly three times as likely to report mobility limitations as persons with low levels, and these effects largely reflected fatigability and fear of uncertainty. The association of harm avoidance with disability was not explained or modified by frailty, physical activity, depressive symptoms, neuroticism, extraversion, or cognition. The results suggest that harm avoidance is associated with disability in old age.

    Substantial harm could result from concurrent cigarette and e-cigarette use (i.e., dual use) were it to undermine smoking cessation. Perceptions of chemical exposure and resulting harms may influence dual use. We conducted a probability-based phone survey of 1164 U.S. adult cigarette smokers in 2014-2015 and analyzed results in 2016. In a between-subjects experiment, smokers heard a hypothetical scenario in which cigarettes and e-cigarettes had the same amount of harmful chemicals or cigarettes had more chemicals than e-cigarettes (10× more, 100× more, or chemicals were present only in cigarettes). Smokers indicated how the scenario would change their interest in dual use and perceived health harms. Few smokers (7%) who heard that the products have the same amount of chemicals were interested in initiating or increasing dual use. However, more smokers were interested when told that cigarettes have 10× more chemicals than e-cigarettes (31%), 100× more chemicals than e-cigarettes (32%), or chemicals were present only in cigarettes (43%) (all p<.001). Individuals told that cigarettes have more chemicals were more likely than those in the "same amount" scenario to perceive that cigarettes would be more harmful than e-cigarettes (79% vs. 41%, OR=5.41, 95% CI=4.08-7.17). These harm perceptions partially explained the relationship between chemical scenario and dual use interest. Smokers associated higher chemical amounts in cigarettes versus e-cigarettes with greater health harms from cigarettes and thus expressed increased interest in dual use. The findings suggest that disclosing amounts of chemicals in cigarette smoke and e-cigarette aerosol could unintentionally encourage dual use.

    This article investigates the pattern of temperament for patients with borderline personality disorder and the impact of psychotherapeutic treatment on temperamental variables. A cohort of patients treated in the Westmead Borderline Personality Disorder Psychotherapy research project completed the Tridimensional Personality Questionnaire. All patients had a diagnosis of borderline personality disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition, criteria. This group scored highly on novelty-seeking and harm avoidance scales and moderately on reward dependence. There was a significant reduction in harm avoidance after 12 months of psychotherapy with a further reduction after 2 years in therapy. Although at variance with Cloninger's original prediction of low harm avoidance in histrionic and borderline patients, results are consistent with other studies in this patient group. The paradox of "self-harmers" scoring highly on harm avoidance may be explained by recognition of the intensity of "psychic pain" in this group. Self-harming behaviors may frequently be motivated by avoidance of a "greater harm" in terms of the inner psychic reality for these patients. Reduction in harm avoidance with psychotherapy could suggest an impact of treatment on temperament or may indicate that the harm avoidance construct is influenced by state variables such as mood.

    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.

    This study examined how narration of harm experiences can regulate self and emotions in ways relevant to well-being. Participants (n = 88, 65% female) were asked to provide 6 narratives about instances when they were victims of harm and 6 narratives about instances when they were perpetrators of harm. Narratives were coded for extent of exploration, growth, damage conclusions and resolution. Participants drew damage conclusions more frequently in victim narratives and growth conclusions more frequently in perpetrator narratives. Both the type of experience (victim or perpetrator) and the way the experience was narrated (references to damage conclusions and resolution) predicted emotion and identity implications, which were, in turn, related to well-being. Implications for narrative approaches to self-regulation are discussed. PMID:26392641

    Mature moral judgments rely on the consideration of a perpetrator’s mental state as well as harmfulness of the outcomes produced. Prior work has focused primarily on the functional correlates of how intent information is neurally represented for moral judgments, but few studies have investigated whether individual differences in neuroanatomy can also explain variation in moral judgments. In the current study, we conducted voxel-based morphometry analyses to address this question. We found that local grey matter volume in the left anterior superior temporal sulcus, a region in the functionally defined theory of mind or mentalizing network, was associated with the degree to which participants relied on information about innocent intentions to forgive accidental harms. Our findings provide further support for the key role of mentalizing in the forgiveness of accidental harms and contribute preliminary evidence for the neuroanatomical basis of individual differences in moral judgments.

  3. Smoked marijuana as a cause of lung injury.

    PubMed

    In many societies, marijuana is the second most commonly smoked substance after tobacco. While delta9-tetrahydrocannabinol (THC) is unique to marijuana and nicotine to tobacco, the smoke of marijuana, like that of tobacco, consists of a toxic mixture of gases and particulates, many of which are known to be harmful to the lung. Although far fewer marijuana than tobacco cigarettes are generally smoked on a daily basis, the pulmonary consequences of marijuana smoking may be magnified by the greater deposition of smoke particulates in the lung due to the differing manner in which marijuana is smoked. Whereas THC causes modest short-term bronchodilation, regular marijuana smoking produces a number of long-term pulmonary consequences, including chronic cough and sputum, histopathologic evidence of widespread airway inflammation and injury and immunohistochemical evidence of dysregulated growth of respiratory epithelial cells, that may be precursors to lung cancer. The THC in marijuana could contribute to some of these injurious changes through its ability to augment oxidative stress, cause mitochondrial dysfunction, and inhibit apoptosis. On the other hand, physiologic, clinical or epidemiologic evidence that marijuana smoking may lead to chronic obstructive pulmonary disease or respiratory cancer is limited and inconsistent. Habitual use of marijuana is also associated with abnormalities in the structure and function of alveolar macrophages, including impairment in microbial phagocytosis and killing that is associated with defective production of immunostimulatory cytokines and nitric oxide, thereby potentially predisposing to pulmonary infection. In view of the growing interest in medicinal marijuana, further epidemiologic studies are needed to clarify the true risks of regular marijuana smoking on respiratory health.

    Indoor air pollution with harmful particulate matter (PM) is mainly caused by cigarette smoke. Super-Slim-Size-Cigarettes (SSL) are considered a less harmful alternative to King-Size-Cigarettes (KSC) due to longer filters and relatively low contents. We ask if "Combined Mainstream and Sidestream Smoke" (CMSS)-associated PM levels of SSL are lower than of KSC and thus are potentially less harmful. PM concentrations in CMSS (PM10, PM2.5, and PM₁) are measured from four cigarette types of the brand Vogue, using an "automatic-environmental-tobacco-smoke-emitter" (AETSE) and laser aerosol spectrometry: SSL-BLEUE, -MENTHE, -LILAS and KSC-La Cigarette and -3R4F reference. This analysis shows that SSL MENTHE emitted the highest amount of PM, and KSC-La Cigarette the lowest. 3R4F reference emitted PM in the middle range, exceeding SSL BLEUE and falling slightly below SSL LILAS. It emerged that PM₁ constituted the biggest proportion of PM emission. The outcome shows significant type-specific differences for emitted PM concentrations. Our results indicate that SSL are potentially more harmful for passive smokers than the respective KSC. However, this study cannot give precise statements about the general influence of the size of a cigarette on PM. Alarming is that PM₁ is responsible for the biggest proportion of PM pollution, since smaller particles cause more harmful effects.

    Executive Summary Objective The objective of this report was to provide the Ministry of Health Promotion (MHP) with a summary of existing evidence-based reviews of the clinical and economic outcomes of population-based smoking cessation strategies. Background Tobacco use is the leading cause of preventable disease and death in Ontario, linked to approximately 13,000 avoidable premature deaths annually – the vast majority of these are attributable to cancer, cardiovascular disease, and chronic obstructive lung disease. (1) In Ontario, tobacco related health care costs amount to $6.1 billion annually, or about $502 per person (including non-smokers) and account for 1.4% of the provincial domestic product. (2) In 2007, there were approximately 1.7 to 1.9 million smokers in Ontario with two-thirds of these intending to quit in the next six months and one-third wanting to quit within 30 days. (3) In 2007/2008, Ontario invested $15 million in cessation programs, services and training. (4) In June 2009, the Ministry of Health Promotion (MHP) requested that MAS provide a summary of the evidence base surrounding population-based smoking cessation strategies. Project Scope The MAS and the MHP agreed that the project would consist of a clinical and economic summary of the evidence surrounding nine population-based strategies for smoking cessation including: Mass media interventions Telephone counselling Post-secondary smoking cessation programs (colleges/universities) Community-wide stop-smoking contests (i.e. Quit and Win) Community interventions Physician advice to quit Nursing interventions for smoking cessation Hospital-based interventions for smoking cessation Pharmacotherapies for smoking cessation, specifically: Nicotine replacement therapies Antidepressants Anxiolytic drugs Opioid antagonists Clonidine Nicotine receptor partial agonists Reviews examining interventions for Cut Down to Quit (CDTQ) or harm reduction were not included in this review.

  6. Does Switching to Reduced Ignition Propensity Cigarettes Alter Smoking Behavior or Exposure to Tobacco Smoke Constituents?

    Introduction: Since 2004, several jurisdictions have mandated that cigarettes show reduced ignition propensity (RIP) in laboratory testing. RIP cigarettes may limit fires caused by smoldering cigarettes, reducing fire-related deaths and injury. However, some evidence suggests that RIP cigarettes emit more carbon monoxide and polycyclic aromatic hydrocarbons, and smokers may alter their smoking patterns in response to RIP cigarettes. Both of these could increase smokers’ exposures to harmful constituents in cigarettes. Methods: An 18-day switching study with a comparison group was conducted in Boston, MA (N = 77), and Buffalo, NY (N = 83), in 2006–2007. Current daily smokers completed 4 laboratory visits and two 48-hr field data collections. After a 4-day baseline, Boston participants switched to RIP cigarettes for 14 days, whereas Buffalo participants smoked RIP cigarettes throughout. Outcome measures included cigarettes smoked per day; smoking topography; salivary cotinine; breath CO; and hydroxylated metabolites of pyrene, naphthalene, phenanthrene, and fluorene. Because the groups differed demographically, analyses adjusted for race, age, and sex. Results: We observed no significant changes in smoking topography or CO exposure among participants who switched to RIP cigarettes. Cigarette use decreased significantly in the switched group (37.7 cigarettes/48 hr vs. 32.6 cigarettes/48 hr, p = .031), while hydroxyphenanthrenes increased significantly (555 ng/g creatinine vs. 669 ng/g creatinine, p = .007). No other biomarkers were significantly affected. Discussion: Small increases in exposure to phenanthrene among smokers who switched to RIP versions were observed, while other exposures and smoking topography were not significantly affected. Toxicological implications of these findings are unclear. These findings should be weighed against the potential public health benefits of adopting RIP design standards for cigarette products.

    Anxiety sensitivity (AS), defined as the extent to which individuals believe that anxiety-related sensations have harmful consequences, is associated with smoking processes and poorer clinical outcomes among trauma-exposed smokers. Yet the specific mechanisms underlying this association are unclear. Smoking-specific avoidance and inflexibility is a construct implicated in multiple manifestations of mood regulation that may underlie smoking behavior. The current study examined the explanatory role of smoking-specific avoidance and inflexibility in terms of the relation between AS and indices of smoking behavior among trauma-exposed smokers. The sample consisted of 217 treatment-seeking adult smokers (44% female; M age = 37.8; SD = 13.2; age range: 18-65 years), who were exposed to at least one lifetime Criterion A trauma event (Diagnostic and Statistical Manual of Mental Disorders [4th ed., text rev.; DSM-IV-TR] Criterion A for trauma exposure). Bootstrap analysis (5,000 re-samples) revealed that AS was indirectly related to the (a) number of cigarettes smoked per day, (b) number of years being a daily smoker, (c) number of failed quit attempts, and (d) heaviness of smoking index among trauma-exposed smokers through its relation with smoking-specific avoidance and inflexibility. These findings provide initial evidence suggesting that smoking-specific avoidance and inflexibility may be an important construct in better understanding AS-smoking relations among trauma-exposed smokers. Future work is needed to explore the extent to which smoking-specific avoidance and inflexibility account for relations between AS and other smoking processes (e.g., withdrawal, cessation outcome) in the context of trauma and smoking comorbidity.

    Cigarettes with reduced circumference are increasingly popular in some countries, hence it is important to understand the effects of circumference reduction on their burning behaviour, smoke chemistry and bioactivity. Reducing circumference reduces tobacco mass burn rate, puff count and static burn time, and increases draw resistance and rod length burned during puff and smoulder periods. Smoulder temperature increases with decreasing circumference, but with no discernible effect on cigarette ignition propensity during a standard test. At constant packing density, mainstream (MS) and sidestream (SS) tar and nicotine yields decrease approximately linearly with decreasing circumference, as do the majority of smoke toxicants. However, volatile aldehydes, particularly formaldehyde, show a distinctly non-linear relationship with circumference and increases in the ratios of aldehydes to tar and nicotine have been observed as the circumference decreases. Mutagenic, cytotoxic and tumorigenic specific activities of smoke condensates (i.e. per unit weight of condensate) decrease as circumference decreases. Recent studies suggest that there is no statistical difference in mouth-level exposure to tar and nicotine among smokers of cigarettes with different circumferences. Commercially available slim cigarettes usually have changes in other cigarette design features compared with cigarettes with standard circumference, so it is difficult to isolate the effect of circumference on the properties of commercial products. However, available data shows that changes in cigarette circumference offer no discernible change to the harm associated with smoking.

    Using academic achievement as the key outcome variable, 7377 Icelandic adolescents were surveyed for cigarette smoking, alcohol use, daytime sleepiness, caffeine use, and potential confounders. Structural equation modeling (SEM) was used to examine direct and indirect effects of measured and latent variables in two models: the first with caffeine excluded and the second with caffeine included. A substantial proportion of variance in academic achievement, which might otherwise have been attributed to the harmful effects of cigarette smoking and alcohol use, was found to be attributable to caffeine. Evidence was obtained that daytime sleepiness, which was found to be independently associated with usage of licit substances (nicotine and alcohol) and caffeine, may be an important mediator of the negative impact of those substances on academic achievement. Findings suggest the importance of including measurements of caffeine consumption in future studies of adolescent substance use.

    Tobacco remains the leading preventable cause of death worldwide. In particular, people with mental illness are disproportionately affected with high smoking prevalence; they account for more than 200,000 of the 520,000 tobacco-attributable deaths in the United States annually and die on average 25 years prematurely. Our review aims to provide an update on smoking in the mentally ill. We review the determinants of tobacco use among smokers with mental illness, presented with regard to the public health HAVE framework of "the host" (e.g., tobacco user characteristics), the "agent" (e.g., nicotine product characteristics), the "vector" (e.g., tobacco industry), and the "environment" (e.g., smoking policies). Furthermore, we identify the significant health harms incurred and opportunities for prevention and intervention within a health care systems and larger health policy perspective. A comprehensive effort is warranted to achieve equity toward the 2025 Healthy People goal of reducing US adult tobacco use to 12%, with attention to all subgroups, including smokers with mental illness. Expected final online publication date for the Annual Review of Public Health Volume 38 is March 20, 2017. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

    Purpose of review Smoking remains the leading cause of preventable morbidity and mortality. Our review highlights research from 2013-2015 on the treatment of cigarette smoking, with a focus on heart patients and cardiovascular outcomes. Recent findings Seeking to maximize the reach and effectiveness of existing cessation medications, current tobacco control research has demonstrated the safety and efficacy of combination treatment; extended use; reduce-to-quit strategies; and personalized approaches to treatment matching. Further, cytisine has gained interest as a lower-cost strategy for addressing the global tobacco epidemic. On the harm reduction front, snus and electronic nicotine delivery systems are being widely distributed and promoted with major gaps in knowledge of the safety of long-term and dual use. Quitlines, comparable in outcome to in-person treatment, avail cessation counseling on a national scale though use rates remain relatively low. Lastly, employee reward programs are gaining attention given the high costs of tobacco use to employers; sustaining quit rates post-payment, however, has proven challenging. Summary Evidence-based cessation treatments exist. Broader dissemination, adoption, and implementation are key to addressing the tobacco epidemic. The cardiology team has a professional obligation to advance tobacco control efforts and can play an important role in achieving a smoke-free future. PMID:26196657

    Abstract Introduction: Little is known about how smokers respond cognitively and emotionally to the experience of “late” relapse after the acute withdrawal phase. This study assessed the kinds of thoughts and feelings that emerge in order to provide a basis for quantitative research assessing prevalence of different types of response and implications for future quit attempts. Methods: Face-to-face in-depth interviews were conducted among 14 people attending a quit smoking clinic in Malaysia who had relapsed after at least 6 weeks of abstinence. Transcripts were analyzed using thematic analysis to enable emergence of important aspects of the experience. Results: Following relapse, smokers often engaged in rationalizations and activities to minimize worry about the harmful effects of smoking by switching to a lower-tar cigarette, reducing the number of cigarette smoked, attempting to reduce cigarette smoke inhalation, comparing themselves with other smokers, and minimizing the health risks associated with smoking. In some cases, smokers retained a “non-smoker” identity despite having relapsed. Conclusion: Smoking relapsers rationalize their failure to quit and minimize their health risk in order to protect their image as non-smokers while it remains a source of identity conflict.

    Mexico ratified the Framework Convention for Tobacco Control in 2004 and is obligated to move forward with implementing its provisions, including Article 8 (Protection from exposure to tobacco smoke). The country has already faced opposition from the tobacco industry. This paper addresses industry tactics against tobacco control, describing the general strategies that have been pursued and the evidence relevant to combating these strategies. The approaches taken by the industry in an effort to discredit the scientific foundation for promoting smokefree environments, the efforts by the industry to propose ventilation of indoor spaces and separation of smokers from nonsmokers as an effective alternative to smokefree places, and finally, the strategy of raising fear of economic losses on the part of the hospitality industry and thereby gaining this sector as an ally in campaigning against smokefree policies are considered. As reviewed in this article: 1) There is scientific consensus on the adverse effects of inhaling SHS; 2) Only smokefree places fully protect nonsmokers from inhaling SHS; and 3) Smokefree policies do not bring economic harm to the hospitality industry.

  19. Moral Distress, Workplace Health, and Intrinsic Harm.

    PubMed

    Weber, Elijah

    2016-05-01

    Moral distress is now being recognized as a frequent experience for many health care providers, and there's good evidence that it has a negative impact on the health care work environment. However, contemporary discussions of moral distress have several problems. First, they tend to rely on inadequate characterizations of moral distress. As a result, subsequent investigations regarding the frequency and consequences of moral distress often proceed without a clear understanding of the phenomenon being discussed, and thereby risk substantially misrepresenting the nature, frequency, and possible consequences of moral distress. These discussions also minimize the intrinsically harmful aspects of moral distress. This is a serious omission. Moral distress doesn't just have a negative impact on the health care work environment; it also directly harms the one who experiences it. In this paper, I claim that these problems can be addressed by first clarifying our understanding of moral distress, and then identifying what makes moral distress intrinsically harmful. I begin by identifying three common mistakes that characterizations of moral distress tend to make, and explaining why these mistakes are problematic. Next, I offer an account of moral distress that avoids these mistakes. Then, I defend the claim that moral distress is intrinsically harmful to the subject who experiences it. I conclude by explaining how acknowledging this aspect of moral distress should reshape our discussions about how best to deal with this phenomenon.

    Smoking is a recurrent, chronic addictive disease that causes multiple diseases and is the main known cause of avoidable morbidity and mortality, constituting a major public health problem. In developed countries, smoking is the main single cause of premature preventable morbidity and mortality. Tobacco combustion releases more than 4,000 toxic substances and more than 50 substances with demonstrated carcinogenic effects; smoking is a risk factor for six of the eight main causes of death worldwide. The treatment of smoking is both effective and cost-effective. Any therapeutic intervention performed by health professions for smoking will have beneficial results. If such interventions are adapted to the individual characteristics of each patient, their efficacy and efficiency will be much greater. All treatments are safe, with generally mild adverse effects that rarely lead to treatment withdrawal. Patients with COPD show higher nicotine dependence and seem to have greater difficulty in quitting smoking. Nevertheless, smoking cessation should be a priority in these patients, as it constitutes the only measure able to halt progression of the disease.

  1. Smoking and reproduction.

    2 of the 5 health warnings that must now appear on American cigarette packs and cigarette advertising refer to some of the increased hazards smoking entails for the woman and her unborn child. Yet, the myriad reproductive risks associated with smoking are little known or considered by the general public--or even by physicians--when compared with the dangers of lung cancer, heart attacks and emphysema. In an attempt to remedy that deficit, 8 government agencies sponsored the 1st International Conference on Smoking and Reproductive Health, held October 15-17, 1985 in San Francisco. Speaker after expert speaker connected smoking during pregnancy with increased risks of low birth weight, miscarriage, infant mortality and morbidity--including poorer health of surviving children up to at least age 3--ectopic pregnancy, infertility, menstrual disorders, early menopause, osteoporosis, cervical cancer and dysplasia, cardiovascular disease and placental abnormalities. Similarly, the conference participants documented the association of smoking among men with lower sperm count and increased prevalence of abnormal sperm. The following measures were urged at the closing statements of the conference: 1) an increased effort to inform doctors and health professionals of these findings; 2) increasing the tax on cigarettes, so that smokers would pay for their own health costs; 3) decreasing or eliminating government subsidies for growing tobacco, while helping growers make the transition to nontobacco crops; 4) making smoking cessation programs more widely available; 5) prohibiting the sale of cigarettes through vending machines; and 6) banning all smoking in the workplace.

    In this study we aimed to determine the smoking habits of the elementary school teacher students and to examine the factors affecting smoking. The prepared questionnaires were applied to 3rd and 4th year students by selecting randomly. The ratio of the students smoking regularly and occasionally was 45.8%. The smoking frequency was higher in male and fourth year students [63 (53.8%) of males, 85 (41.3%) of females (p< 0.05); 102 (52.3%) students in 4th year and 46 (35.9%) students in 3rd year (p< 0.01)]. The most common reason of not smoking was the harmful effect of smoking to life (45.8%), the most common reason of initiating smoking was to decrease their stress (43.1%) and the most common reason to keep on smoking was difficulty of quitting (56.7%). When compared to nonsmokers, the smoking frequency of mothers, brothers, all family members and close friends of smoker students were higher (p< 0.05). There was significant difference between depression symptom scores of the students who were smoking and the ones who were nonsmokers (14.9 +/- 7.6 in smokers, 9.8 +/- 6.3 in nonsmokers; p< 0.05). The smoking frequency among school teacher students was very high. The smoking habits of close friends, regular alcohol intake, and presence of depressive symptoms were increasing the risk of smoking. It will be beneficial for public health to plan and apply appropriate education program for students who will be the first teachers of the primary school students, not to start smoking.

    ABSTRACT OBJECTIVE: To determine the factors affecting the smoking habits of high school students, their thoughts about changes resulting from anti-smoking laws, and how they are affected by those laws. METHODS: In this cross-sectional study, 11th-grade students at eight high schools in Ankara, Turkey, were invited to complete a questionnaire. RESULTS: A total of 1,199 students completed the questionnaire satisfactorily. The mean age of the respondents was 17.0 ± 0.6 years; 56.1% were female, of whom 15.3% were smokers; and 43.9% were male, of whom 43.7% were smokers (p < 0.001). The independent risk factors for smoking were male gender, attending a vocational school, having a sibling who smokes, having a friend who smokes, and poor academic performance. Of the respondents, 74.7% were aware of the content of anti-smoking laws; 81.8% approved of the restrictions and fines; and 8.1% had quit smoking because of those laws. According to the respondents, the interventions that were most effective were the (television) broadcast of films about the hazards of smoking and the ban on cigarette sales to minors. The prevalence of smoking was highest (31.5%) among students attending vocational high schools but lowest (7.5%) among those attending medical vocational high schools. Although 57.1% of the smokers were aware of the existence of a smoking cessation helpline, only 3.7% had called, none of whom had made any attempt to quit smoking. CONCLUSIONS: Although most of the students evaluated were aware of the harmful effects of smoking and approved of the anti-smoking laws, only a minority of those who smoked sought professional help to quit.

  4. Is post-mortem harm possible? Understanding death harm and grief.

    PubMed

    Tomasini, Floris

    2009-10-01

    The purpose of this article is not to affirm or deny particular philosophical positions, but to explore the limits of intelligibility about what post-mortem harm means, especially in the light of improper post-mortem procedures at Bristol and Alder Hey hospitals in the late 1990s. The parental claims of post-mortem harm to dead children at Alder Hey Hospital are reviewed from five different philosophical perspectives, eventually settling on a crucial difference of perspective about how we understand harm to the dead. On the one hand there is the broadly 'analytical' tradition(1) of thinking that predicates the notion of harm on the basis of an existing subject. Since the dead are non-existent persons, it makes little sense to view the dead as being harmed. On the other hand, there is a phenomenological perspective, where the dead, in respect to the experience of grief, are existentially absent. This forms the basis that it is possible to harm grieving parent's experiences of how their dead are treated. The article ends with a short examination of what harming the dead implies for traditional bioethical concerns, namely, obtaining informed consent from significant others when planning medical research on the newly dead.

    The ages at which 18- to 24-year-old college students started smoking and its relationship to subsequent smoking were explored, using data from the 1995 National College Health Risk Behavior Survey. Most students (70%) had tried smoking; among those who had tried, 42% were current smokers, 19% were current frequent smokers, and 13% were current daily smokers. The majority (81%) who had ever smoked daily began doing so at age 18 years or younger, and 19% began smoking daily at age 19 years or older. Women were as likely as men to report ever having smoked a whole cigarette or ever having smoked daily. Most students (82%) who had ever smoked daily had tried to quit, but 3 in 4 were still smokers. Policies and programs designed to prevent the initiation of smoking and to help smokers quit are needed at both the high school and the college levels to reduce the proportion of young adults who smoke cigarettes.

    Background Waterpipe tobacco smoking is a traditional method of tobacco use, especially in the Eastern Mediterranean Region (EMR), but its use is now spreading worldwide. Recent epidemiological data, for example, show that waterpipe smoking has become the most prevalent tobacco use method among adolescents in the EMR, and the second most prevalent in the US. Waterpipes are used socially, often being shared between friends or family at home, or in dedicated bars and cafes that provide waterpipes to patrons. Because the smoke passes through a reservoir of water, waterpipe tobacco smoking is perceived as being less harmful than other methods of tobacco use. At least in some cultures, women and girls are more likely to use a waterpipe than to use other forms of tobacco, and it is popular among younger smokers. Accumulating evidence suggests that some waterpipe smokers become addicted, have difficulty quitting, and experience similar health risks as cigarette smokers. Objectives To evaluate the effectiveness of tobacco cessation interventions for waterpipe users. Search methods We searched the Cochrane Tobacco Addiction Review Group specialized register in June 2015. We also searched MEDLINE, EMBASE, PsycINFO and CINAHL, using variant terms and spellings (‘waterpipe’ or ‘narghile’ or ‘arghile’ or ‘shisha’ or ‘goza’ or ‘narkeela’ or ‘hookah’ or ‘hubble bubble’). We searched for trials, published or unpublished, in any language, and especially in regions where waterpipe use is widespread. Selection criteria We sought randomized, quasi-randomized or cluster-randomized controlled trials of smoking cessation interventions for waterpipe smokers of any age or gender. The primary outcome of interest was abstinence from tobacco use, measured at six months post-cessation or longer, regardless of whether abstinence was biochemically verified. We included interventions that were pharmacological (for example, nicotine replacement therapy (NRT) or

    Mammography screening for breast cancer is widely available in many countries. Initially praised as a universal achievement to improve women's health and to reduce the burden of breast cancer, the benefits and harms of mammography screening have been debated heatedly in the past years. This review discusses the benefits and harms of mammography screening in light of findings from randomized trials and from more recent observational studies performed in the era of modern diagnostics and treatment. The main benefit of mammography screening is reduction of breast-cancer related death. Relative reductions vary from about 15 to 25% in randomized trials to more recent estimates of 13 to 17% in meta-analyses of observational studies. Using UK population data of 2007, for 1,000 women invited to biennial mammography screening for 20 years from age 50, 2 to 3 women are prevented from dying of breast cancer. All-cause mortality is unchanged. Overdiagnosis of breast cancer is the main harm of mammography screening. Based on recent estimates from the United States, the relative amount of overdiagnosis (including ductal carcinoma in situ and invasive cancer) is 31%. This results in 15 women overdiagnosed for every 1,000 women invited to biennial mammography screening for 20 years from age 50. Women should be unpassionately informed about the benefits and harms of mammography screening using absolute effect sizes in a comprehensible fashion. In an era of limited health care resources, screening services need to be scrutinized and compared with each other with regard to effectiveness, cost-effectiveness and harms.

    Among the fire victims, respiratory tract injury resulted from smoke inhalation is the major cause of death. Particulate substances in smoke, toxic and harmful gas, and chemical substances act together would rapidly induce the occurrence of dramatic pathophysiologic reaction in the respiratory tract, resulting in acute injury to the respiratory tract, thus inducing serious injury to it and acute respiratory distress syndrome, leading to death of the victims. In recent years, the pathophysiologic mechanism of severe smoke inhalation injury has been gradually clarified, thus appreciable advances in its treatment have been achieved. This paper is a brief review of above-mentioned aspects.

Smoking tobacco is a significant source of indoor air pollution and is harmful to human health. The aim of this research was to find both the best non-invasive matrices (from among saliva, urine, semen and sweat) for evaluating environmental exposure to tobacco smoke and the relationships between thiocyanates (biomarkers of environmental tobacco smoke exposure) and other inorganic ions in these matrices collected from active and passive smokers and also non-smokers.

    2014-06-01

    More than 400,000 deaths occur per year in the United States that are attributable to cigarette smoking; the risks to the general public are widely known. The risk to women, especially those who are pregnant, is less commonly known. During pregnancy, smoking increases the risk of low birth weight infants, placental problems (previa and/or abruption), chronic hypertensive disorders, and fetal death. It is proposed that much of this happens because of vasoconstriction with decreased uterine blood flow from nicotine, carbon monoxide toxicity, and increased cyanide production. Infants of smoking mothers have increased risks, such as sudden infant death syndrome.

    Abstract Electronic cigarettes (E-cigarettes) are a potential means of addressing the harm to public health caused by tobacco smoking by offering smokers a less harmful means of receiving nicotine. As e-cigarettes are a relatively new phenomenon, there are limited scientific data on the longer-term health effects of their use. This study describes a robust in vitro method for assessing the cytotoxic response of e-cigarette aerosols that can be effectively compared with conventional cigarette smoke. This was measured using the regulatory accepted Neutral Red Uptake assay modified for air–liquid interface (ALI) exposures. An exposure system, comprising a smoking machine, traditionally used for in vitro tobacco smoke exposure assessments, was adapted for use with e-cigarettes to expose human lung epithelial cells at the ALI. Dosimetric analysis methods using real-time quartz crystal microbalances for mass, and post-exposure chemical analysis for nicotine, were employed to detect/distinguish aerosol dilutions from a reference Kentucky 3R4F cigarette and two commercially available e-cigarettes (Vype eStick and ePen). ePen aerosol induced 97%, 94% and 70% less cytotoxicity than 3R4F cigarette smoke based on matched EC50 values at different dilutions (1:5 vs. 1:153 vol:vol), mass (52.1 vs. 3.1 μg/cm2) and nicotine (0.89 vs. 0.27 μg/cm2), respectively. Test doses where cigarette smoke and e-cigarette aerosol cytotoxicity were observed are comparable with calculated daily doses in consumers. Such experiments could form the basis of a larger package of work including chemical analyses, in vitro toxicology tests and clinical studies, to help assess the safety of current and next generation nicotine and tobacco products.

    The Malaysian official Islamic authorities have issued a "fatwa" (Islamic ruling) regarding smoking practice which prohibits Muslims from smoking because of its potential harm to health. Since the prevalence of smoking among Malaysian students is high, this study was designed to explore the perceptions and opinions of Malaysian Muslim students towards smoking in International Islamic University of Malaysia. A prospective, cross-sectional study was conducted among School of Science students in International Islamic University Malaysia. Convenience sampling approach was used to recruit 323 students based on sample size calculation. A content- and face-validated questionnaire was used to collect the data from the participants. Non-smokers highly supported the fatwa on smoking forbiddance than smokers (94 vs 64.3 %, p = 0.001). A significant proportion of non-smokers believed that Islam prohibits smoking because of its potential harm (94.9 vs 71.4 %, p = 0.001). Majority of smokers agreed that addiction is the main barrier towards smoking cessation (78.6 vs 61.5 %, p = 0.019). The results showed positive influences of Islamic beliefs on the non-smokers. Further studies are required to validate these findings by surveying other universities of Malaysia.

    Tobacco smoking is the most serious health and social problem. Most of the elderly smokers start smoking at age of 13 to 15 years. The aim of the thesis was to survey the tobacco smoking and the knowledge about the harmfulness of the tobacco smoking among the young people. The investigated material is the 365 persons' group of boys and girls from the 13 schools in the administrative district of Sokółka, who took part in the antinicotine educational program. The questionnaire was used before the program was started. Even though the investigated people evaluated their knowledge about the harmfulness of tobacco smoking very well, they still attempt this risky behavior. More often the young people smoke in order to impress their friends. 18% boys and girls attempted smoking in the primary schools and 35% in the high schools. The survey shows that every third pupil in the primary schools recived the proposal of smoking. Among the investigated people the proportion of smokers is lower as compared to the others of the similar age group in Poland in 1998. Experimenting on smoking is dangerous as the proportion of smokers is rising with their age. It is necessary to introduce the prophylactic actions in every type of school. The programs should be concentrated on preventing the youth from the risky addictions and reducing the risky factors.

  19. Mammography screening. Benefits, harms, and informed choice.

    The rationale for breast cancer screening with mammography is deceptively simple: catch it early and reduce mortality from the disease and the need for mastectomies. But breast cancer is a complex problem, and complex problems rarely have simple solutions. Breast screening brings forward the time of diagnosis only slightly compared to the lifetime of a tumour, and screen-detected tumours have a size where metastases are possible. A key question is if screening can prevent metastases, and if the screen-detected tumours are small enough to allow breast conserving surgery rather than mastectomy. A mortality reduction can never justify a medical intervention in its own right, but must be weighed against the harms. Overdiagnosis is the most important harm of breast screening, but has gained wider recognition only in recent years. Screening leads to the detection and treatment of breast cancers that would otherwise never have been detected because they grow very slowly or not at all and would not have been detected in the woman's lifetime in the absence of screening. Screening therefore turns women into cancer patients unnecessarily, with life-long physical and psychological harms. The debate about the justification of breast screening is therefore not a simple question of whether screening reduces breast cancer mortality. This dissertation quantifies the primary benefits and harms of screening mammography. Denmark has an unscreened "control group" because only two geographical regions offered screening over a long time-period, which is unique in an international context. This was used to study breast cancer mortality, overdiagnosis, and the use of mastectomies. Also, a systematic review of overdiagnosis in five other countries allowed us to show that about half of the screen-detected breast cancers are overdiagnosed. An effect on breast cancer mortality is doubtful in today's setting, and overdiagnosis causes an increase in the use of mastectomies. These findings are

    HIV prevalence worldwide among people who inject drugs (PWID) is around 19%. Harm reduction for PWID includes needle-syringe programs (NSPs) and opioid substitution therapy (OST) but often coupled with antiretroviral therapy (ART) for people living with HIV. Numerous studies have examined the effectiveness of each harm reduction strategy. This commentary discusses the evidence of effectiveness of the packages of harm reduction services and their cost-effectiveness with respect to HIV-related outcomes as well as estimate resources required to meet global and regional coverage targets. NSPs have been shown to be safe and very effective in reducing HIV transmission in diverse settings; there are many historical and very recent examples in diverse settings where the absence of, or reduction in, NSPs have resulted in exploding HIV epidemics compared to controlled epidemics with NSP implementation. NSPs are relatively inexpensive to implement and highly cost-effective according to commonly used willingness-to-pay thresholds. There is strong evidence that substitution therapy is effective, reducing the risk of HIV acquisition by 54% on average among PWID. OST is relatively expensive to implement when only HIV outcomes are considered; other societal benefits substantially improve the cost-effectiveness ratios to be highly favourable. Many studies have shown that ART is cost-effective for keeping people alive but there is only weak supportive, but growing evidence, of the additional effectiveness and cost-effectiveness of ART as prevention among PWID. Packages of combined harm reduction approaches are highly likely to be more effective and cost-effective than partial approaches. The coverage of harm reduction programs remains extremely low across the world. The total annual costs of scaling up each of the harm reduction strategies from current coverage levels, by region, to meet WHO guideline coverage targets are high with ART greatest, followed by OST and then NSPs.

    Information about the rate of smoking and factors associated with initiating and maintaining the behaviour is scarce in Palestine. The aim of this study was to explore the rate of and attitudes towards smoking among An-Najah National University students. During spring 2010, a questionnaire adopted from the Global Health Professionals Survey and the Global Youth Tobacco Survey was administered to 954 randomly selected full-time students. Overall 34.7% of the study sample were cigarette or waterpipe smokers, and this rate was higher among males than females (52.7% versus 16.5%). In logistic regression analysis, sex (male), type of college (humanities), older age and higher family income were predictors of current smoking status. Smokers had more negative attitudes to banning smoking in public areas on campus and to education about the harmful effects of smoking. Antismoking programmes with special attention to males and students in humanities are badly needed.

    Idiopathic clubfoot is a common orthopedic birth defect that affects approximately 135,000 newborns worldwide. It is characterized by equinus, varus and adductus deformities of the ankle and foot. While numerous studies suggest a multifactorial etiology, the specific genetic and environmental components have yet to be delineated. Maternal smoking during pregnancy is the only common environmental factor consistently shown to increase the risk for clubfoot. Moreover, a positive family history of clubfoot, in conjunction with maternal smoking, increases the risk twenty-fold. These findings suggest that genetic variation in smoking metabolism (xenobiotic) genes may increase susceptibility to clubfoot. Based on this reasoning, we interrogated eight candidate genes (CYP1A1, CYP1A2, CYP1B1, CYP2A6, EPHX1, NAT2, GSTM1 and GSTT1), chosen based on their involvement in xenobiotic metabolism. Twenty-two SNPs and two null alleles in these genes were genotyped in a dataset composed of nonHispanic white and Hispanic multiplex and simplex families. Only rs1048943/CYP1A1 had significantly altered transmission in the aggregate and multiplex NHW datasets (p=0.003 and p=0.009, respectively). Perturbation of CYP1A1 can cause an increase in harmful, adduct forming metabolic intermediates. A significant interaction between EPHX1 and NAT2 was also found (p=0.007). Importantly, for CYP1A2, significant maternal (p=0.03; RR=1.24; 95% CI: 1.04–1.44) and fetal (p=0.01; RR=1.33; 95% CI: 1.13–1.54) genotypic effects were identified, suggesting that both maternal and fetal genotypes can negatively impact limb development. No association was found between maternal smoking status and variation in xenobiotic metabolism genes. Together, these results suggest that xenobiotic metabolism genes are unlikely to play a major role in clubfoot, however, perturbation of this pathway may still play a contributory role.

    Dioxins in cigarettes, smoke, and ash were determined using gas chromatography/mass spectrometry. The total concentration of polychlorinated dibenzo-p-dioxins (PCDDs) in cigarette smoke was approximately 5.0 micrograms/m3 at the maximum level, whereas various congeners from tetra-octa-chlorodibenzo-p-dioxin (-CDD) were detected. Particullary, the total concentration of hepta-CDD congeners was the highest among these congeners. Mass fragmentograms of various PCDD congeners were similar to those in flue gas samples collected from a municipal waste incinerator. The PCDD congeners that were not present in the cigarettes were found in the smoke samples. The 2,3,7,8-TCDD toxic equivalent value--an index for effects on humans--for total PCDDs in smoke was 1.81 ng/m3 using the toxic factor of the United States Environment Protection Agency. Daily intake of PCDDs by smoking 20 cigarettes was estimated to be approximately 4.3 pg.kg body weight/day. This value was close to that of the ADIs: 1-5 pg.kg body weight/day reported in several countries. A heretofore unrecognized health risk was represented by the presence of PCDDs in cigarette smoke.

    In view of the severe adverse effects that smoking has on health, much energy is being invested especially to prevent adolescents from starting to smoke or to get them to stop. Since orthodontists have regular contact with a rather large group of young people during the period when they begin to smoke, a study was conducted to determine whether these specialists could be engaged in an organized anti-smoking programme. One of the relevant considerations was that orthodontists are succesful in motivating adolescents to wear braces. Research has shown that dentists in an organized programme in the United States were able to achieve a significant reduction in the percentage of adult smokers. The research findings revealed, however, that the orthodontists nevertheless lacked sufficient training and motivation to be effectively employed in an anti-smoking programme. The results of some clinical trials with adolescent patients were disappointing, but they did make clear what needs to be done to achieve improvements. Well organized involvement in a sound anti-smoking programme in The Netherlands will require very careful preparation and will only be able to start after well designed and successful clinical trials.

    Abstract To systematically assess the relationship between smoking and glioma risk. A dose–response meta-analysis of case–control and cohort studies was performed. Pertinent studies were identified by searching database and reference lists. Random-effects model was employed to pool the estimates of the relative risks (RRs) with corresponding 95% confidence intervals (CIs). A total of 19 case–control and 6 cohort studies were included. Overall, compared with those who never smoked, the pooled RR and 95% CI was 0.98 (0.92–1.05) for ever smoker. The subgroups were not significantly different regarding risk of glioma except the group of age at start smoking (RR = 1.17, 95% CI: 0.93–1.48 for age < 20; RR = 1.25, 95% CI: 1.02–1.52 for age ≥ 20). Dose–response analysis also suggested no significant association between smoking and the risk of glioma, although some evidence for a linear relationship between smoking and glioma risk was observed. In conclusion, this meta-analysis provides little support for a causal relationship between smoking and risk of glioma. PMID:26765433

    Smoking behavior is a threat for Indonesian teenagers, including in the city of Jayapura, Papua province. The purpose of this study was to access Jayapura teenagers smoking behavior and knowledge including parents and other family members. The study was conducted on 78 respondents (grade 7, aged 11-14 years old), using cluster random sampling for selecting the public and private junior high school in Jayapura. The data collected was smoking behavior of respondents, parents and other family members (using self-reported questionnaire), and respondents' knowledge about the dangers of smoking (using tests with Cronbach's alpha 0.701). Data were analyzed descriptively and analytically using Chi-square, 95 % level of significant. The results showed 29.3 % of teenagers, 69.23 % of parents and 25.6 % of other family members were smokers, their knowledge was low (an average score of 60.81 out of 100), there was no significant statistical relationship between knowledge and smoking behavior among respondents (p = 0.079), and there is no significant relationship between teenagers behavior with the behavior of the parents (p = 0.609) and other family members (p = 0.578), 87 % of teenagers became smokers because there were individuals who smoke at home.

    Homelessness and drug use often overlap and the harms of substance use are exacerbated by homelessness. Responding to the twin problems of homelessness and substance use is an important aspect of strategies to end homelessness. The introduction and development of ten year plans to end homelessness in North America heralds a new era of systemic responses to homelessness. Central to many of these plans is the adoption of 'Housing First' as a policy response. Housing First focuses directly on housing people regardless of current patterns of substance use. As such, harm reduction is a key principle of Housing First. In this paper, we examine Housing First as an example of the integration of housing and harm reduction and then put forth a community level policy framework to further promote the integration of harm reduction as part of a response to homelessness. Drawing on Rhodes' risk environment framework and current evidence of Housing First and harm reduction, we describe four key policy areas for action: (1) social inclusion policies; (2) adequate and appropriate supply of housing; (3) on demand harm reduction services and supports and (4) systemic and organizational infrastructure. We conclude by identifying areas for future research.

    Exposure to secondhand smoke from burning tobacco products causes stroke, lung cancer, and coronary heart disease in adults (1,2). Children who are exposed to secondhand smoke are at increased risk for sudden infant death syndrome, acute respiratory infections, middle ear disease, more severe asthma, respiratory symptoms, and slowed lung growth (1,2). Secondhand smoke exposure contributes to approximately 41,000 deaths among nonsmoking adults and 400 deaths in infants each year (2). This report updates a previous CDC report that evaluated state smoke-free laws in effect from 2000-2010 (3), and estimates the proportion of the population protected by comprehensive smoke-free laws. The number of states, including the District of Columbia (DC), with comprehensive smoke-free laws (statutes that prohibit smoking in indoor areas of worksites, restaurants, and bars) increased from zero in 2000 to 26 in 2010 and 27 in 2015. The percentage of the U.S. population that is protected increased from 2.72% in 2000 to 47.8% in 2010 and 49.6% in 2015. Regional disparities remain in the proportions of state populations covered by state or local comprehensive smoke-free policies, as no state in the southeast has a state comprehensive law. In addition, nine of the 24 states that lack state comprehensive smoke-free laws also lack any local comprehensive smoke-free laws. Opportunities exist to accelerate the adoption of smoke-free laws in states that lack local comprehensive smoke-free laws, including those in the south, to protect nonsmokers from the harmful effects of secondhand smoke exposure.

    Although the suicidal and self-harming behaviour of individuals is often associated with similar behaviours in people they know, little is known about the impact of perceived social norms on those behaviours. In a range of other behavioural domains (e.g., alcohol consumption, smoking, eating behaviours) perceived social norms have been found to strongly predict individuals' engagement in those behaviours, although discrepancies often exist between perceived and reported norms. Interventions which align perceived norms more closely with reported norms have been effective in reducing damaging behaviours. The current study aimed to explore whether the Social Norms Approach is applicable to suicidal and self-harming behaviours in adolescents. Participants were 456 pupils from five Scottish high-schools (53% female, mean age = 14.98 years), who completed anonymous, cross-sectional surveys examining reported and perceived norms around suicidal and self-harming behaviour. Friedman's ANOVA with post-hoc Wilcoxen signed-ranks tests indicated that proximal groups were perceived as less likely to engage in or be permissive of suicidal and self-harming behaviours than participants' reported themselves, whilst distal groups tended towards being perceived as more likely to do so. Binary logistic regression analyses identified a number of perceived norms associated with reported norms, with close friends' norms positively associated with all outcome variables. The Social Norms Approach may be applicable to suicidal and self-harming behaviour, but associations between perceived and reported norms and predictors of reported norms differ to those found in other behavioural domains. Theoretical and practical implications of the findings are considered.

  14. Electrofishing and its harmful effects on fish

    Electrofishing, a valuable sampling technique in North America for over half a century, involves a very dynamic and complex mix of physics, physiology, and behavior that remains poorly understood. New hypotheses have been advanced regarding "power transfer" to fish and the epileptic nature of their responses to electric fields, but these too need to be more fully explored and validated. Fishery researchers and managers in the Colorado River Basin, and elsewhere, are particularly concerned about the harmful effects of electrofishing on fish, especially endangered species. Although often not externally obvious or fatal, spinal injuries and associated hemorrhages sometimes have been documented in over 50% of fish examined internally. Such injuries can occur anywhere in the electrofishing field at or above the intensity threshold for twitch. These injuries are believed to result from powerful convulsions of body musculature (possibly epileptic seizures) caused mostly by sudden changes in voltage as when electricity is pulsed or switched on or off. Significantly fewer spinal injuries are reported when direct current, low-frequency pulsed direct current (<30 Hz), or specially designed pulse trains are used. Salmoniae are especially susceptible. Endangered cyprinids of the Colorado River Basin are generally much less susceptible, enough so to allow cautious use of less harmful currents for most recovery monitoring and research. However, the endangered catostomid Xyrauchen texanus appears sufficiently susceptible to warrant a continued minimal-use policy. Other harmful effects, such as bleeding at gills or vent and excessive physiological stress, are also of concern. Mortality, usually by asphyxiation, is a common result of excessive exposure to tetanizing intensities near electrodes or poor handling of captured specimens. Reported effects on reproduction are contradictory, but electrofishing over spawning grounds can harm embryos. Electrofishing is often considered the

    Method: Narrative review of published papers and other data sources (for example, conference abstracts and internet based information) on snus use, use of other tobacco products, and changes in health status in Sweden. Results: Snus is manufactured and stored in a manner that causes it to deliver lower concentrations of some harmful chemicals than other tobacco products, although it can deliver high doses of nicotine. It is dependence forming, but does not appear to cause cancer or respiratory diseases. It may cause a slight increase in cardiovascular risks and is likely to be harmful to the unborn fetus, although these risks are lower than those caused by smoking. There has been a larger drop in male daily smoking (from 40% in 1976 to 15% in 2002) than female daily smoking (34% in 1976 to 20% in 2002) in Sweden, with a substantial proportion (around 30%) of male ex-smokers using snus when quitting smoking. Over the same time period, rates of lung cancer and myocardial infarction have dropped significantly faster among Swedish men than women and remain at low levels as compared with other developed countries with a long history of tobacco use. Conclusions: Snus availability in Sweden appears to have contributed to the unusually low rates of smoking among Swedish men by helping them transfer to a notably less harmful form of nicotine dependence.

    Objectives Tobacco companies frame smoking as an informed choice, a strategy that holds individuals responsible for harms they incur. Few studies have tested this argument, and even fewer have examined how informed indigenous smokers or those from minority ethnicities are when they start smoking. We explored how young adult Māori and Pacific smokers interpreted ‘informed choice’ in relation to smoking. Participants Using recruitment via advertising, existing networks and word of mouth, we recruited and undertook qualitative in-depth interviews with 20 Māori and Pacific young adults aged 18–26 years who smoked. Analyses Data were analysed using an informed-choice framework developed by Chapman and Liberman. We used a thematic analysis approach to identify themes that extended this framework. Results Few participants considered themselves well informed and none met more than the framework's initial two criteria. Most reflected on their unthinking uptake and subsequent addiction, and identified environmental factors that had facilitated uptake. Nonetheless, despite this context, most agreed that they had made an informed choice to smoke. Conclusions The discrepancy between participants' reported knowledge and understanding of smoking's risks, and their assessment of smoking as an informed choice, reflects their view of smoking as a symbol of adulthood. Policies that make tobacco more difficult to use in social settings could help change social norms around smoking and the ease with which initiation and addiction currently occur. PMID:27188813

    2015-01-01

    Smoking cigarettes is a gendered activity with sex- and gender-specific uptake trends and cessation patterns. While global male smoking rates have peaked, female rates are set to escalate in the 21st century, especially in low and middle income countries. Hence, smoking cessation for women will be an ongoing issue and requires refreshed attention. Public health and health promotion messages are being challenged to be increasingly tailored, taking gender into account. Women-centred approaches that include harm-reduction, motivational interviewing and trauma-informed elements are the new frontiers in interventions to encourage smoking cessation for women. Such approaches are linked to the meanings of smoking to women, the adaptive function of, and the overall role of smoking cigarettes in the context of women’s lives. These approaches respect gender and sex-related factors that affect smoking and smoking cessation and respond to these issues, not by reinforcing destructive or negative gender norms, but with insight. This article discusses a women-centred approach to smoking cessation that could underpin initiatives in clinical, community or public health settings and could inform campaigns and messaging.

    This study applies a symbolic interaction perspective to the investigation of smoking frequency and a person’s desire to quit smoking cigarettes. Data derived from 485 Atlanta area adult smokers provide a diverse, community-based sample of married and single men and women, aged 18 to 70 years old with a range of income, education, and occupational experiences. Multiple regression was used to analyze the data in order to explore the influence of social demographic characteristics, social interaction, subjective assessments of health, self conceptions, and smoker identity on smoking frequency and quitting smoking. Findings include: (1) the relationship with a non-smoker and hiding smoking negatively impacted smoking frequency, while perceiving positive consequences from smoking has a positive effect on smoking frequency; and (2) perceiving positive consequences of smoking was negatively related to the desire to quit smoking, while a negative smoker identity has a positive influence on the desire to quit. Taken as a whole, the symbolic interaction-inspired variables exerted strong and independent effects on both smoking frequency and quitting smoking. Future smoking interventions should focus on meanings and perceived consequences of smoking in general, and on the smoker identity in the development of campaigns to encourage quitting cigarette smoking.

    2003-01-01

    Objective: To document the development of the low tar harm reduction programme in Australia, including tobacco industry responses. Data sources: Tobacco industry documents, retail tobacco journals, newspapers, medical journals, and Anti-Cancer Council of Victoria (ACCV) newsletters and archival records. Study selection: Documents on the strategies and knowledge bases of the ACCV, other Australian health authorities, and the tobacco industry. Results: The ACCV built a durable system for measuring and publicising the tar and nicotine yields of Australian cigarettes and influencing their development. The tobacco industry initially sought to block the development of this system but later appeared to cooperate with it, as is evidenced by the current market dominance of low tar brands. However, behind the scenes, the industry used its substantial knowledge advantage regarding compensatory smoking and its ability to re-engineer cigarettes to gain effective control of the system and subvert the ACCV's objectives. Conclusions: Replacement of the low tar programme with new means of minimising the harms from cigarette smoking should be a policy priority for the Australian government. This will require regulation, rather than further voluntary agreements, and stringent monitoring of successor programmes will be necessary. PMID:14645950

  1. Prospects for a nicotine-reduction strategy in the cigarette endgame: Alternative tobacco harm reduction scenarios.

    PubMed

    Kozlowski, Lynn T

    2015-06-01

    Some major national and international tobacco control organisations favour mandating a reduction in nicotine content of cigarettes to non-addictive levels as a tobacco control tool. Reducing nicotine content, it is argued, will make tobacco smoking less attractive. The 2009 U.S. Food and Drug Administration's regulation of cigarettes appears to have the power to reduce nicotine to non-addictive levels provided it is not taken to zero. A consideration of the U.S. context, however, raises doubts about (a) whether this will ever be practicable and (b), if practicable, how long it will take to implement. Current versions of the nicotine-reducing strategy propose the systematic, incentivised use of less harmful nicotine/tobacco products as elements of the mandatory cigarette nicotine-reduction strategy. Time will tell if and when mandatory nicotine reduction in tobacco cigarettes will occur and what impact it might have on smoking prevalence. The question posed here is "Why wait?" Resources used in implementing reduction in nicotine content have an opportunity cost. In the meantime, nicotine-maintaining harm reduction strategies can have nearer term effects on tobacco use as an individual and a public health issue.

    Objective This study is the first to explore the impact of graphic cigarette labels with physical harm images on members of American Indian/Alaska Native (AI/AN) communities. The aim of this article is to investigate how AI/AN respond to particular graphic warning labels. Methods The parent study recruited smokers, at-risk smokers and non-smokers from three different age groups (youths aged 13–17 years, young adults aged 18–24 years and adults aged 25+ years) and five population subgroups with high smoking prevalence or smoking risk. Using nine graphic labels, this study collected participant data in the field via an iPad-administered survey and card sorting of graphic warning labels. This paper reports on findings for AI/AN participants. Results After viewing graphic warning labels, participants rated their likelihood of talking about smoking risks to friends, parents and siblings higher than their likelihood of talking to teachers and doctors. Further, this study found that certain labels (eg, the label of the toddler in the smoke cloud) made them think about their friends and family who smoke. Conclusions Given the influence of community social networks on health beliefs and attitudes, health communication using graphic warning labels could effect change in the smoking habits of AI/AN community members. Study findings suggest that graphic labels could serve as stimuli for conversations about the risks of smoking among AI/AN community members, and could be an important element of a peer-to-peer smoking cessation effort.

    PubMed

    1997-04-01

    Surgical smoke evacuation systems are high-flow vacuum sources used to capture, at the surgical site, the smoke aerosols and gases generated during the use of lasers and electrosurgical units (ESUs). In this study, we evaluated 16 evacuation systems, from 10 suppliers, designed and marketed for use in the operating room for general surgery. For our testing, we focused on the performance of the systems (particularly their ability to capture smoke particles under simulated surgical conditions) and their ease of use and quality of construction. We also examined the projected costs of each system over a seven-year life cycle. We rated the systems separately for two different evacuation applications (1) general-purpose applications, for which the system would, in many cases, be used with a handheld nozzle (the traditional capture device used with these systems), and (2) ESU-pencil-based evacuation applications only, for which the system would always be used with a pencil-based wand. (We report on ESU-pencil-based smoke evacuation wands in a separate Evaluation in this issue.) While we found most units to be Acceptable, we did rate two units Acceptable-Not Recommended for both applications and one unit Unacceptable for general-purpose applications.

    Tobacco-specific nitrosamines (TSNAs) are N-nitroso-derivatives of pyridine-alkaloids (e.g., nicotine) present in tobacco and cigarette smoke. Two TSNAs, N'-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), are included on the Food and Drug Administration's list of harmful and potentially harmful constituents (HPHCs) in tobacco products and tobacco. The amounts of four TSNAs (NNK, NNN, N-nitrosoanabasine (NAB), and N'-nitrosoanatabine (NAT)) in the tobacco and mainstream smoke from 50 U.S. commercial cigarette brands were measured from November 15, 2011 to January 4, 2012 using a validated HPLC/MS/MS method. Smoke samples were generated using the International Organization of Standardization (ISO) and Canadian Intense (CI) machine-smoking regimens. NNN and NAT were the most abundant TSNAs in tobacco filler and smoke across all cigarette brands, whereas NNK and NAB were present in lesser amounts. The average ratios for each TSNA in mainstream smoke to filler content is 29% by the CI smoking regimen and 13% for the ISO machine-smoking regimen. The reliability of individual TSNAs to predict total TSNA amounts in the filler and smoke was examined. NNN, NAT, and NAB have a moderate to high correlation (R(2) = 0.61-0.98, p < 0.0001), and all three TSNAs individually predict total TSNAs with minimal difference between measured and predicted total TSNA amounts (error < 7.4%). NNK has weaker correlation (R(2) = 0.56-0.82; p < 0.0001) and is a less reliable predictor of total TSNA quantities. Tobacco weight and levels of TSNAs in filler influence TSNA levels in smoke from the CI machine-smoking regimen. In contrast, filter ventilation is a major determinant of levels of TSNAs in smoke by the ISO machine-smoking regimen. Comparative analysis demonstrates substantial variability in TSNA amounts in tobacco filler and mainstream smoke yields under ISO and CI machine-smoking regimens among U.S. commercial cigarette brands.

    To develop more effective anti-smoking programs, it is important to understand the factors that influence people to smoke. Guided by attribution theory, a longitudinal study was conducted to investigate how individuals’ cognitive attributions for smoking were associated with subsequent smoking development and through which pathways. Middle and high school students in seven large cities in China (N=12,382; 48.5% boys and 51.5% girls) completed two annual surveys. Associations between cognitive attributions for smoking and subsequent smoking initiation and progression were tested with multilevel analysis, taking into account plausible moderation effects of gender and baseline smoking status. Mediation effects of susceptibility to smoking were investigated using statistical mediation analysis (MacKinnon, 2008). Six out of eight tested themes of cognitive attributions were associated with subsequent smoking development. Curiosity (β=0.11, p<0.001) and autonomy (β=0.08, p=0.019) were associated with smoking initiation among baseline non-smokers. Coping (β=0.07, p<0.001) and social image (β=0.10, p=<.0001) were associated with smoking progression among baseline lifetime smokers. Social image (β=0.05, p=0.043), engagement (β=0.07, p=0.003), and mental enhancement (β=0.15, p<0.001) were associated with smoking progression among baseline past 30-day smokers. More attributions were associated with smoking development among males than among females. Susceptibility to smoking partially mediated most of the associations, with the proportion of mediated effects ranging from 4.3% to 30.8%. This study identifies the roles that cognitive attributions for smoking play in subsequent smoking development. These attributions could be addressed in smoking prevention programs. PMID:22112425

    It is known that exposure to smoking cues increases urge to smoke (UTS), but little is known about other media factors that might also increase UTS. We hypothesized that horror/ thriller movies might also increase UTS by increasing negative affect. We surveyed 536 movie patrons who were smokers aged 18 years or older. Subjects had exited 26 movies, of which 12 contained smoking and two were horrorfilms, one with and one without smoking. We used random effects regression to assess the association between exposure to movie smoking, movie horror, both and UTS, controlling for confounding factors. Median age was 26 years and 52% were female. Mean UTS was 5.9, 6.6, 6.6, and 8.7 for smokers exiting movies without smoking, with smoking, horror without smoking and horror with smoking respectively. Smoking in movies was associated with a significantly higher UTS (0.63 [95% CI 0.31-0.94]). Horror with smoking increased UTS by 2.8 points (95% C.I. 2.3, 3.5); the horror without smoking estimate was 0.88, but not statistically significant. This short report offers preliminary evidence that movie horror as one factor besides visual smoking cues that could increase UTS in a community setting.

    Although the relationship between parental and adolescent smoking has been linked to health consequences of smoking, limited study has explored the specific association between exposure to smoking and adolescent smoking topography (the way a cigarette is smoked). As a first step in this line of enquiry, smoking topography measures were collected from 67 adolescent dependent smokers. Participants smoked one cigarette of their own brand while being monitored by a computer-based smoking-topography unit and completed questionnaires about their time spent daily with parents who smoke. Pearson's correlation analysis revealed that time spent daily with parents who smoke was significantly associated with maximum puff velocity (r=0.285, p=.019), a parameter predicting later pulmonary morbidity. ANOVAs, after a median split, were consistent with correlation analyses. There was a significant group effect on puff velocity (F(2,66)=5.197, p=.008); no significant relationship was found with puff volume (F(2,66)=.617) or puff duration (F(2,66)=.776). A post hoc Tukey HSD test indicated puff velocity was higher in the "high time spent" (M=54.37, SD=12.03) than in the "low time spent" group (M=45.59, SD=9.91) and in the group with non-smoking parents (M=44.96, SD=10.17). Future research with a larger non-treatment seeking sample of adolescents aimed at preventing tobacco smoking related diseases should further examine parental influences on adolescent smoking, including potential modeling effects.

    This book approaches the smoking debate from a new angle. The thrust of the study was to determine if smokers are cognizant of the risks connected with smoking, and if so, how these risk beliefs influence the decision to smoke. The study evaluates the government's anti-smoking policies and recommends changes to these policies. Viscusi does not address the actual health risks of smoking independent of risk perception and subsequent behavioral data; the US Surgeon General's smoking risk assessments are acknowledged at face vale.

    Smoking is a prevalent behaviour in the population. The aim of this review is to bring to light the effects of smoking on dental implants. These facts will assist dental professionals when implants are planned in tobacco users. A search of “PubMed” was made with the key words “dental implant,” “nicotine,” “smoking,” “tobacco,” and “osseointegration.” Also, publications on tobacco control by the Government of India were considered. For review, only those articles published from 1988 onward in English language were selected. Smoking has its influence on general as well as oral health of an individual. Tobacco negatively affects the outcome of almost all therapeutic procedures performed in the oral cavity. The failure rate of implant osseointegration is considerably higher among smokers, and maintenance of oral hygiene around the implants and the risk of peri-implantitis are adversely affected by smoking. To increase implant survival in smokers, various protocols have been recommended. Although osseointegrated dental implants have become the state of the art for tooth replacement, they are not without limitations or complications. In this litigious era, it is extremely important that the practitioner clearly understands and is able and willing to convey the spectrum of possible complications and their frequency to the patients.

    2016-08-03

    Given the large availability of nicotinic acetylcholine receptors (nAChRs) throughout the brain, and the wide range of neurotransmitter systems affected (norepinephrine, serotonin and dopamine), nicotine influences a wide variety of cognitive domains such as sensorial, motor, attentional, executive function, learning and memory. This article reviews current state of the art research on the effects of nicotine upon cognition. There are different neurobiological mechanisms involved in acute/chronic smoking and nicotine abstinence. Smoking reinforcement could be due to the initial cognitive improvement, that is, individuals can learn that smoking temporarily increases cognitive functioning (improving some components of attention and memory). These acute nicotine effects improve (i) cognitive performance above smokers' normal levels, and (ii) cognitive disruption resulting from nicotine abstinence. Both neurobiological effects act as reinforcers to nicotine use, greatly contributing to the development of nicotine dependence. However, heavy smoking is associated with cognitive impairment and cognitive decline in middle age. Future clinical research should investigate the role of positive and negative cognitive effects of nicotine in smoking cessation treatment. This is clearly an important scientific issue, with insufficient current data from which to draw definitive conclusions.

  14. Racial resentment and smoking.

    2015-02-01

    Racial resentment (also known as symbolic racism) is among the most widely tested measures of contemporary prejudice in political science and social psychological research over the past thirty years. Proponents argue that racial resentment reflects anti-black emotion obtained through pre-adult socialization. In light of affect-based models of substance use, this paper examined the association between racial resentment and smoking in a national sample of non-Hispanic white, black, and Hispanic respondents. Data come from the 2012 American National Election Study, which contained two measures of smoking. The results of ordinal logistic regression models indicate a positive association between racial resentment and smoking among non-Hispanic whites (N = 2133) that is not present among blacks (N = 693) or Hispanics (N = 660). Models controlled for age, education, income, gender, political ideology, region, and mode of interview. Furthermore, analyses indicated that a measure of race-related affect, admiration and sympathy towards blacks, partially mediated the association between racial resentment and smoking. For non-Hispanic whites, racial resentment appears to constitute a risk factor for smoking. Future studies should further specify the conditions linking substance use to the race-related affective component of racial resentment.

  15. Automobile dirty smoke eliminator

    An automobile dirty smoke eliminator is disclosed which mainly consists of two oval tin plates externally, and upper and lower exhaust pipes , left and right support plates, a blade, a discharge chamber, a discharge pipe, etc. internally. The principle of the present invention mainly consists in making use of the effect of mixing water and gas to entirely eliminate automobile dirty smoke. When the dirty smoke (exhaust gas) of automobile enters into the lower exhaust pipe of the present invention, the blade at the outlet of said lower exhaust pipe submerged in water is impacted by the compression force derived from the engine exhaust stroke so as to generate a mixture of said water and exhaust gas and to form a whirlpool having many buddles. The effect of walls of left and right support plates promote the toxin in the said dirty smoke (Exhaust gas) automatically to deposit in the said water. The surplus toxin is discharged through the upper exhaust pipe and then mixed with the water to form a colorless, odorless nontoxious fog-like vapor which exhausts through the discharge pipe in order to achieve the best result of eliminating the said dirty smoke (Exhaust gas).

    Objective Self-harm is common and is of considerable public health concern. There is an ongoing debate regarding how self-harm should be classified. The aim of this study was to characterize associations between self-harm and impulsivity, including from the perspective of formal mental disorders and neuropsychological functioning. Method Total 333 adults (mean [SD] age 22.6 (3.6) years, 61% male) were recruited from the general community, and undertook detailed clinical and cognitive assessments. History of self-harm was quantified using the Self-Harm Inventory (SHI), which asks about 22 self-harm behaviors (classic self-harm behaviors as well as broader types of behavior that may be relevant, such as engaging in emotionally abusive relationships). Principal components analysis was used to identify latent dimensions of self-harming behaviors. Relationships between self-harm dimensions and other measures were characterized using ordinary least squares regression. Results Principal Components Analysis yielded a three factor solution, corresponding to self-injurious self-harm (e.g. cutting, overdoses, burning), interpersonal related self-harm (e.g. engaging in emotionally or sexually abusive relationships), and reckless self-harm (e.g. losing one’s job deliberately, driving recklessly, abusing alcohol). Regression modelling showed that all three dimensions of self-harm were associated with lower quality of life. Classic and interpersonal self-harm dimensions were associated with impulse control disorders (ICDs) whereas reckless self-harm was associated with other mainstream mental disorders besides ICDs. Only interpersonal self-harm was significantly associated with other impulsive measures ( less risk adjustment on the Cambridge Gambling Task). Conclusions This study suggests the existence of three distinct subtypes or ‘latent factors’ of self-harm: all three appear clinically important in that they are linked with worse quality of life. Clinicians should

    While the 'low-tar' scheme has been widely recognised as a misleading tactic used by the tobacco industry to deceive the public about the true risks of cigarette smoking, a similar campaign using the slogan of 'less harmful, low tar' was launched by the Chinese tobacco industry, that is, State Tobacco Monopoly Administration/China National Tobacco Corporation and began to gain traction during the last decade. Despite the fact that no sufficient research evidence supports the claims made by the industry that these cigarettes are safer, the Chinese tobacco industry has continued to promote them using various health claims. As a result, the production and sales of 'less harmful, low-tar' cigarettes have increased dramatically since 2000. Recently, a tobacco industry senior researcher, whose main research area is 'less harmful, low-tar' cigarettes, was elected as an Academician to the prestigious Chinese Academy of Engineering for his contribution to developing 'less harmful, low-tar' cigarettes. The tobacco researcher's election caused an outcry from the tobacco control community and the general public in China. This paper discusses the Chinese tobacco industry's 'less harmful, low-tar' initiatives and calls for the Chinese government to stop the execution of this deceptive strategy for tobacco marketing.

    Smoking during pregnancy is associated with various adverse effects on pregnancy and fetal development, carries a lot of serious complications such as spontaneous abortion, placental abruption, and reduced birth weight of the newborn. Children of smoking mothers have an increased risk of premature birth, low birth weight, sudden infant death syndrome and respiratory diseases during infancy. Smoking also causes long-term risk of maternal health problems such as: heart disease, cancer, emphysema, chronic obstructive pulmonary disease and higher mortality rate. Because women are more likely to quit smoking during pregnancy than at any other time, there are attempts to increase motivation and help them to stop smoking at the procreative phase of their life. The article describes interventions that are carried out in Loma Linda, where the educational program "When You Smoke Your Baby Smokes" reminds parents about the health effects of smoking during pregnancy and harmful impact on child's health caused by second-hand smoke. Another threat to health and environment of our children, is the nicotine coming from indirect exposure to tobacco smoke. Residual nicotine that persists in high concentrations on the interior surfaces, including clothing, is forming in the reaction of nitric acid carcinogenic compounds of specific nitrosamines. In addition, ozone and related atmospheric oxidants react with nicotine smoke or smoke coming from the second-hand smoke, giving the smallest particles with high risk of asthma. Efforts towards reducing exposure to tobacco smoke coming from the passive and indirect smoking should be placed at a high priority throughout the European Union.

    Caffeine consumption and cigarette smoking tend to occur within the same individuals and at the same time. One potential explanation for this co-use is that caffeine consumption increases subjective smoking reinforcement. Electronic diaries were used to collect momentary reports of smoking, caffeine consumption, temptation/urge to smoke, and subjective smoking reinforcement in 74 prequit smokers. Momentary reports of caffeine consumption and smoking were associated, replicating previous findings. These results remained significant when contextual factors (time of day, weekday/weekend, presence of others, presence of others smoking, location, and past hour alcohol consumption) were covaried. Caffeine consumption was also associated with positive cigarette appraisals and reports of strong temptation/urge to smoke and urge reduction from the prior cigarette. Under the conditions of caffeine consumption versus at other times, smokers were significantly more likely to report their last cigarette as producing a rush/buzz, being pleasant, relaxing, and tasting good. The effects for temptation/urge to smoke and rush/buzz varied as a function of latency since smoking. Caffeine consumption increased reports of urge to smoke and rush/buzz only when smoking occurred more than 15 minutes prior to the diary entry. Findings suggest that caffeine consumption influences some aspects of smoking motivation or affects memorial processing of smoking reinforcement.

    The health risks associated with second hand smoke (SHS) are well-known. However, little is known about exposure to SHS in cars and risk of smoking uptake. This paper investigates the association between pre-adolescents reported exposure to smoking in cars and prevalence of early stage smoking activity. Data from Keeping Kids Smokefree baseline surveys of students were used to investigate smoking status and reported exposure to smoking in cars. Log binomial regression analyses were used to investigate if reported exposure to SHS in cars was associated with smoking prevalence. 83% of 5676 students invited took part. After controlling for all variables reported exposure to smoking in cars and homes were significantly associated with increased risk of initiated smoking (RR 1.87, 95% CI 1.43-2.44, and RR 1.5, 95% CI 1.13-1.97, respectively). Exposure to smoking in cars was substantially and significantly associated with risk of current smoking (RR 3.21, 95% CI 1.45-7.08). Early smoking uptake is associated with students' reported exposure to smoking in cars which confirms the importance of protecting children from SHS. Smoking in cars is under parental control and therefore modifiable. Moreover, children's reports of SHlS exposure offer a simple way of identifying families who can be targeted for tobacco control interventions.

    Background Smoking rates among the general population in Bosnia and Herzegovina are extremely high, and national campaigns to lower smoking rates have not yet begun. As part of future activities of the Queen's University Family Medicine Development Program in the Balkans Region, technical assistance may be provided to Bosnia and Herzegovina to develop of national tobacco control strategies. This assistance may focus on training doctors and nurses on smoking cessation strategies with a view to helping their patients to stop smoking. Given this important role that health professionals have, data is needed on smoking rates as well as on smoking behaviour among doctors and nurses in Bosnia and Herzegovina. This study therefore seeks to determine the smoking rates and behaviour of family medicine physicians and nurses in Bosnia and Herzegovina and to determine how well prepared they feel with respect to counselling their patients on smoking cessation strategies. Methods The WHO Global Health Professional Survey, a self-administered questionnaire, was distributed to physicians and nurses in 19 Family Medicine Teaching Centres in Bosnia and Herzegovina in June 2002. Smoking rates and behaviour, as well as information on knowledge and attitudes regarding smoking were determined for both physicians and nurses. Results Of the 273 physicians and nurses currently working in Family Medicine Teaching Centres, 209 (77%) completed the questionnaire. Approximately 45% of those surveyed currently smoke, where 51% of nurses smoked, compared to 40% of physicians. With respect to knowledge and attitudes, all respondents agreed that smoking is harmful to one's health. However, "ever" smokers, compared to "never" smokers, were less likely to agree that health professionals who smoke were less likely to advise patients to quit smoking than non-smoking health professionals. Less than half of physicians and nurses had received formal training in smoking cessations strategies, but about two

    This study assessed the knowledge of the harmful effects of tobacco use among vulnerable populations in Bangladesh and whether vulnerability was associated with the presence of complete home smoking bans. Data came from Wave 3 (2011-2012) of the International Tobacco Control (ITC) Bangladesh Survey, a nationally-representative survey of 3131 tobacco users and 2147 non-users. Socio-demographic measures of disadvantage were used as proxy measures of vulnerability, including sex, residential location, education and income. Outcome measures were awareness of the harmful effects of (a) cigarette smoking and (b) smokeless tobacco use and (c) whether respondents had complete smoking bans in their homes. Logistic regression was used to examine whether the adjusted prevalence of each outcome differed by socio-demographic proxies of vulnerability. Smaller percentages of women, the illiterate, urban slum residents and low-income Bangladeshis were aware of the health harms of tobacco. These vulnerable groups generally had lower odds of awareness compared to the least disadvantaged groups. Incomplete knowledge of tobacco's harms may prevent vulnerable groups from taking steps to protect their health. Development goals, such as increasing literacy rates and empowering women, can complement the goals of WHO's Framework Convention on Tobacco Control.

    Background In the absence of comprehensive smoking bans in public places, bars and nightclubs have the highest concentrations of secondhand tobacco smoke, posing a serious health risk for workers in these venues. Objective To assess exposure of bar and nightclub employees to secondhand smoke, including non-smoking and smoking employees. Methods Between 2007 and 2009, we recruited approximately 10 venues per city and up to 5 employees per venue in 24 cities in the Americas, Eastern Europe, Asia and Africa. Air nicotine concentrations were measured for 7 days in 238 venues. To evaluate personal exposure to secondhand smoke, hair nicotine concentrations were also measured for 625 non-smoking and 311 smoking employees (N=936). Results Median (interquartile range [IQR]) air nicotine concentrations were 3.5 (1.5, 8.5) µg/m3 and 0.2 (0.1, 0.7) µg/m3 in smoking and smoke-free venues, respectively. Median (IQR) hair nicotine concentrations were 6.0 (1.6, 16.0) ng/mg and 1.7 (0.5, 5.5) ng/mg in smoking and non-smoking employees, respectively. After adjustment for age, sex, education, living with a smoker, hair treatment and region, a 2-fold increase in air nicotine concentrations was associated with a 30% (95% confidence interval 23%, 38%) increase in hair nicotine concentrations in non-smoking employees and with a 10% (2%, 19%) increase in smoking employees. Conclusions Occupational exposure to secondhand smoke, assessed by air nicotine, resulted in elevated concentrations of hair nicotine among non-smoking and smoking bar and nightclub employees. The high levels of airborne nicotine found in bars and nightclubs and the contribution of this exposure to employee hair nicotine concentrations support the need for legislation measures that ensure complete protection from secondhand smoke in these venues.

    Objectives. We provided estimates of noncombustible tobacco product (electronic nicotine delivery systems [ENDS]; snus; chewing tobacco, dip, or snuff; and dissolvables) use among current and former smokers and examined harm perceptions of noncombustible tobacco products and reasons for their use. Methods. We assessed awareness of, prevalence of, purchase of, harm perceptions of, and reasons for using noncombustible tobacco products among 1487 current and former smokers from 8 US designated market areas. We used adjusted logistic regression to identify correlates of noncombustible tobacco product use. Results. Of the sample, 96% were aware of at least 1 noncombustible tobacco product, but only 33% had used and 21% had purchased one. Noncombustible tobacco product use was associated with being male, non-Hispanic White, younger, and more nicotine dependent. Respondents used noncombustible tobacco products to cut down or quit cigarettes, but only snus was associated with a higher likelihood of making a quit attempt. Users of noncombustible tobacco products, particularly ENDS, were most likely to endorse the product as less harmful than cigarettes. Conclusions. Smokers may use noncombustible tobacco products to cut down or quit smoking. However, noncombustible tobacco product use was not associated with a reduction in cigarettes per day or cessation.

  11. Effect of smokeless tobacco product marketing and use on population harm from tobacco use policy perspective for tobacco-risk reduction.

    PubMed

    Kozlowski, Lynn T

    2007-12-01

    This article presents policy perspectives on the marketing of smokeless tobacco products to reduce population harm from tobacco use. Despite consensus that smokeless tobacco products as sold in the United States are less dangerous than cigarettes, there is no consensus on how to proceed. Diverse factions have different policy concerns. While the tobacco industry is exempted from U.S. Food and Drug Administration (FDA) oversight, the pharmaceutical industry whose nicotine replacement therapy (NRT) medicines compete with smokeless tobacco as noncombustible nicotine-delivery systems are regulated by the FDA. Some public health experts support smokeless tobacco use to reduce population harm from tobacco; other public health experts oppose promoting smokeless tobacco for harm reduction. Adult consumers can freely purchase currently-marketed smokeless tobacco products and even more-deadly cigarettes. Concerns with and advantages of smokeless tobacco products are discussed. In that noncombustible medicinal nicotine-delivery systems have been proven to be effective smoking-cessation aids, smokeless tobacco, as another source of psychoactive doses of nicotine, could be used similarly, in a dose-response fashion as a smoking-cessation aid (consistent with FDA principles for evaluating generic versions of drugs). Price measures should be used on tobacco products to make costs to consumers proportional to product health risks (which would make smokeless tobacco much cheaper than cigarettes), and smokeless tobacco should be encouraged as an option for smoking cessation in adult smokers, particularly for those who have failed to stop smoking using NRT or other methods.

    The exhaust from a solid propellant rocket motor usually contains condensed species. These particles, also called 'Primary Smoke', are often prejudicial to missile detectability and to the guidance system. To avoid operational problems it is necessary to know and quantify the effects of particles on all aspects of missile deployment. A brief description of the origin of the primary smoke is given. It continues with details of the interaction between particles and light as function of both particles and light properties (nature, size, wavelength, etc). The effects of particles on plume visibility, attenuation of an optical beam propagated through the plume and the contribution of particles on optical signatures of the plume are also described. Finally, various methods used in NATO countries to quantify the primary smoke effects are discussed.

    Objective Little is known about the consequences of tobacco smoking stigma on smokers and how smokers may internalize smoking-related stigma. This review summarizes existing literature on tobacco smoking self-stigma, investigating to what extent smokers are aware of negative stereotypes, agree with them and apply them to themselves. Methods We carried out a systematic search of Pubmed/Web of Science/PsycInfo databases for articles related to smoking self-stigma through June 2013. Reference lists and citations of included studies were also checked and experts were contacted. After screening articles for inclusion/exclusion criteria we performed a quality assessment and summarized findings according to the stages of self-stigma as conceptualized in Corrigan’s progressive model of self-stigma (aware, agree, apply and harm). Initial searches yielded 570 articles. Results Thirty of these articles (18 qualitative and 12 quantitative studies) met criteria for our review. Awareness of smoking stigma was virtually universal across studies. Coping strategies for smoking stigma and the degree to which individuals who smoke internalized this stigma varied both within and across studies. There was considerable variation in positive, negative, and non-significant consequences associated with smoking self-stigma. Limited evidence was found for subgroup differences in smokingrelated stigma. Conclusion While there is some evidence that smoking self-stigma leads to reductions in smoking, this review also identified significant negative consequences of smoking self-stigma. Future research should assess the factors related to differences in how individuals respond to smoking stigma. Public health strategies which limit the stigmatization of smokers may be warranted.

  14. Patterns of Smoking and Snus Use in Sweden: Implications for Public Health.

    There has been concern that the availability of alternative less harmful forms of nicotine might inhibit smoking cessation and/or encourage those who would not otherwise have smoked to do so. The plausibility of such effects can be best assessed by looking at population trends in use of smoking in relation to alternatives. This paper looks at the relationships between snus use and smoking in Sweden. Analyses are based on a data set for the period January 2003 to February 2011 from a long-term study covering nationally representative samples of the Swedish population aged 18-79, with a total study population of 60,675 individuals. Questionnaires made it possible to identify detailed tobacco use categories and use trajectories. The results showed that uptake of snus use is much more common in males than females. Those who began daily tobacco use using snus were much less likely to subsequently take up smoking than those who had not, both among males (17.6% vs. 45.9%), and females (8.2% vs. 40.2%). Further, among those who started using snus after starting as smokers, 76.3% of men and 71.6% of women had stopped smoking completely, including 31.5% of the men and 28.6% of the women who had quit all forms of tobacco. Indeed, those who were primary snus users were also more likely to have quit altogether than those who only ever smoked. Snus was also reported as the most common smoking cessation aid among men and yielded higher success rates than nicotine replacement therapy and other alternatives. As conclusions, snus has both contributed to decreasing initiation of smoking and, when used subsequent to smoking, appears to facilitate smoking cessation. All these effects suggest that the availability and use of snus has been a major factor behind Sweden's record-low prevalence of smoking and the lowest level of tobacco-related mortality among men in Europe.

  15. Research Opportunities Related to Establishing Standards for Tobacco Products Under the Family Smoking Prevention and Tobacco Control Act

    PubMed Central

    2012-01-01

    Introduction: This paper was written in response to a request from the U.S. National Cancer Institute. The goal is to discuss some research directions related to establishing tobacco product standards under the Family Smoking Prevention and Tobacco Control Act, which empowers the U.S. Food and Drug Administration to regulate tobacco products. Potential research related to tobacco product ingredients, nicotine, and harmful or potentially harmful constituents of tobacco products is discussed. Discussion: Ingredients, which are additives, require less attention than nicotine and harmful or potentially harmful constituents. With respect to nicotine, the threshold level in tobacco products below which dependent users will be able to freely stop using the product if they choose to do so is a very important question. Harmful and potentially harmful constituents include various toxicants and carcinogens. An updated list of 72 carcinogens in cigarette smoke is presented. A crucial question is the appropriate levels of toxicants and carcinogens in tobacco products. The use of carcinogen and toxicant biomarkers to determine these levels is discussed. Conclusions: The need to establish regulatory standards for added ingredients, nicotine, and other tobacco and tobacco smoke constituents leads to many interesting and potentially highly significant research questions, which urgently need to be addressed.

  16. No excuses: televised pornography harms children.

    PubMed

    Benedek, E P; Brown, C F

    1999-01-01

    All youngsters are at some risk from exposure to televised pornography, as described above. At particular risk for harm, however, are the most vulnerable children in our society--children in single-parent homes, children with mental and emotional disturbances, mentally challenged children, children who have been physically and/or sexually abused, and children in dysfunctional families. Youngsters for whom television serves as a babysitter or parental surrogate unfortunately are exposed to few competing influences to television viewing. In addition, parents in such homes are least likely to know what their children are viewing and to be able to pass on their own values about sex and sexual behavior. The main possible effects of televised pornography that must concern us as clinicians, educators, and parents are modeling and imitation of language heard and behaviors observed in televised pornography; negative interference with children's normal sexual development; emotional reactions such as nightmares and feelings of anxiety, guilt, confusion, and/or shame; stimulation of premature sexual activity; development of unrealistic, misleading, and/or harmful attitudes toward sex and adult male-female relationships; and undermining of family values with resultant conflict between parents and children. Much more research is clearly needed on this topic. Because of the ethical and procedural problems surrounding research on children exposed to pornography, ideal research designs may never be possible. Nonetheless, we hope that this article will stimulate further discussion and work. To devise public policy that protects children from potentially harmful material while at the same time respecting the media's First Amendment rights, such public discourse and responsible research are essential.

    The use of visual methods is becoming increasingly common and accepted in health research. This paper explores the opportunities and constraints of using photo-based methods in the context of a community-based participatory research study on how to engage people living with HIV in conversations about a hospital's recently introduced harm reduction policy. Using a blended approach of photovoice and photo-elicited interviews, we provided participants (n = 16) with cameras and asked them to take a series of photos that "show how you feel about or have experienced harm reduction as a Casey House client." We reflect on methodological insights from the study to think through the process of doing photo-based work on a stigmatized topic in a small hospital setting by foregrounding: 1) how the act of taking photos assisted participants in visualizing connections between space, harm reduction, and substance use; 2) expectations of participation and navigating daily health realities; and 3) issues of confidentiality, anonymity and stigma in clinical settings. These reflections provide a case study on the importance of critically examining the process of engaging with photo-based methods. We conclude the paper by re-thinking issues of context and photo-based methods. Rather than viewing context as a neutral backdrop to apply a method, context should be viewed as an active force in shaping what can or cannot be done or produced within the space. Photo-based methods may offer an effective community-engagement strategy but may require modification for use in a clinical setting when working on a stigmatized topic with individuals with complex health care needs. Given the potential of visual methods as a community engagement strategy, research teams are advised to understand the entire process as a data collection opportunity so that these methods can be further explored in a variety of contexts.

    2011-05-01

    This study developed a multilevel model of the interpersonal harming behavior associated with social comparison processes in work teams. We tested this model using temporally lagged data from a sample of student teams (Study 1) and cross-sectional data from a sample of work teams in a telecommunication services company (Study 2). In both studies, social relations analyses revealed that in teams with less cooperative goals, comparison to a higher performing team member was positively associated with interpersonal harming behavior, but only when expectations of future performance similarity to that member were low. The interactive relationship of social comparison and expected future performance similarity with interpersonal harming was buffered, however, in teams with more cooperative goals.

Program (needle exchange, low threshold access to treatment) prevent harms associated with opioid use (HIV, overdose…). Effective treatment involves a set of pharmacological and psychosocial interventions. The benefits of maintenance programmes increase as long as the person remains in treatment (many years). Relapse is a symptom of the disorder or a sign of abstinence failure. Treatment aims to improve quality of life in a comprehensive and individualised assessment.

    Cannabis is the most commonly smoked illicit substance in the world. It can be smoked alone in plant form (marijuana) but it is mainly smoked mixed with tobacco. The combined smoking of cannabis and tobacco is a common-place phenomenon in our society. However, its use is responsible for severe pulmonary consequences. The specific impact of smoking cannabis is difficult to assess precisely and to distinguish from the effect of tobacco. Marijuana smoke contains polycyclic aromatic hydrocarbons and carcinogens at higher concentration than tobacco smoke. Cellular, tissue, animal and human studies, and also epidemiological studies, show that marijuana smoke is a risk factor for lung cancer. Cannabis exposure doubles the risk of developing lung cancer. This should encourage clinicians to identify cannabis use and to offer patients support in quitting.

    This article examines gambling harms from both gamblers and affected others' perspectives. Participants (3076 gamblers and 2129 affected others) completed a retrospective survey that elicited information on harms they experienced from gambling across their lifetime. Their responses were analyzed through testing measurement invariance, estimating item-response theoretic parameters, calculating percentages, confidence intervals, and correlations, as well as regressions. The results indicated large commonalities in the experience of harms reported by gamblers and affected others. Further, gamblers appeared to 'export' about half of the harms they experienced to those around them. The findings also provided detailed profiles of evolving harms as problem gambling severity varies.

    2012-02-01

    Smoking prevalence is higher among disadvantaged groups, and disadvantaged smokers may face higher exposure to tobacco's harms. Uptake may also be higher among those with low socioeconomic status (SES), and quit attempts are less likely to be successful. Studies have suggested that this may be the result of reduced social support for quitting, low motivation to quit, stronger addiction to tobacco, increased likelihood of not completing courses of pharmacotherapy or behavioral support sessions, psychological differences such as lack of self-efficacy, and tobacco industry marketing. Evidence of interventions that work among lower socioeconomic groups is sparse. Raising the price of tobacco products appears to be the tobacco control intervention with the most potential to reduce health inequalities from tobacco. Targeted cessation programs and mass media interventions can also contribute to reducing inequalities. To tackle the high prevalence of smoking among disadvantaged groups, a combination of tobacco control measures is required, and these should be delivered in conjunction with wider attempts to address inequalities in health.

  10. Harmful cyanobacterial blooms: causes, consequences, and controls.

    PubMed

    Paerl, Hans W; Otten, Timothy G

    2013-05-01

    Cyanobacteria are the Earth's oldest oxygenic photoautotrophs and have had major impacts on shaping its biosphere. Their long evolutionary history (≈ 3.5 by) has enabled them to adapt to geochemical and climatic changes, and more recently anthropogenic modifications of aquatic environments, including nutrient over-enrichment (eutrophication), water diversions, withdrawals, and salinization. Many cyanobacterial genera exhibit optimal growth rates and bloom potentials at relatively high water temperatures; hence global warming plays a key role in their expansion and persistence. Bloom-forming cyanobacterial taxa can be harmful from environmental, organismal, and human health perspectives by outcompeting beneficial phytoplankton, depleting oxygen upon bloom senescence, and producing a variety of toxic secondary metabolites (e.g., cyanotoxins). How environmental factors impact cyanotoxin production is the subject of ongoing research, but nutrient (N, P and trace metals) supply rates, light, temperature, oxidative stressors, interactions with other biota (bacteria, viruses and animal grazers), and most likely, the combined effects of these factors are all involved. Accordingly, strategies aimed at controlling and mitigating harmful blooms have focused on manipulating these dynamic factors. The applicability and feasibility of various controls and management approaches is discussed for natural waters and drinking water supplies. Strategies based on physical, chemical, and biological manipulations of specific factors show promise; however, a key underlying approach that should be considered in almost all instances is nutrient (both N and P) input reductions; which have been shown to effectively reduce cyanobacterial biomass, and therefore limit health risks and frequencies of hypoxic events.

    Studies have shown that smoking is a learnt behavior, often initiated during adolescence. This paper aims to describe tobacco-related knowledge, attitude and associations among school adolescents aged 13-15 with exposure to anti-smoking information. Using data from the Global Youth Tobacco Survey (GYTS) in Viet Nam, 2014, knowledge was measured through 4 questions about tobacco use, and attitude was assessed through 3 questions on personal, social and environmental aspects. Students giving most anti-tobacco responses to all questions were considered as having correct knowledge or appropriate attitude or both. Access to anti-smoking information was determined by exposure to any media messages on tobacco control during the past 30 days and teaching in school about the danger of tobacco use during the past 12 months. A substantial percentage of students thought that being near others who smoke might be harmful to them and smoking is harmful to health (89.4% and 89.6% respectively). However, only 46.4% reported that it is definitely difficult to quit smoking and 66.9% thought that smoking for only 1 or 2 years, once stopped, is harmful to health. Slightly more than half of the respondents reported appropriate attitude that young smokers have fewer friends than others and smoking makes them less attractive and less comfortable at social events. Noticing anti-smoking messages in the media together with having lessons in school about the dangers of tobacco substantially increased the likelihood of having correct knowledge, appropriate attitude and both. Despite relatively high awareness about smoking harms, effective educational communication is still highly needed to improve the level of comprehensive knowledge and an appropriate attitude regarding tobacco use.

    2011-01-01

    Summary Moral judgments, whether delivered in ordinary experience or in the courtroom, depend on our ability to infer intentions. We forgive unintentional or accidental harms and condemn failed attempts to harm. Prior work demonstrates that patients with damage to the ventromedial prefrontal cortex (VMPC) deliver abnormal judgments in response to moral dilemmas, and that these patients are especially impaired in triggering emotional responses to inferred or abstract events (e.g., intentions), as opposed to real or actual outcomes. We therefore predicted that VMPC patients would deliver abnormal moral judgments of harmful intentions in the absence of harmful outcomes, as in failed attempts to harm. This prediction was confirmed in the current study: VMPC patients judged attempted harms including attempted murder as more morally permissible relative to controls. These results highlight the critical role of the VMPC in processing harmful intent for moral judgment. PMID:20346759

    2016-12-23

    Research in high income countries suggests that anti-smoking television advertisements with emotionally evocative graphic messages or personal testimonials that depict serious consequences from smoking are the most effective. Research to determine the most effective smoking cessation messages for low- and middle-income countries is needed to inform campaign development in these countries. Fifty-four male Taiwanese smokers, aged 18-34, rated advertisements and participated in a focus group to evaluate eight antismoking television advertisements with contrasting messaging strategies. Participants individually evaluated advertisements, after which they participated in a semi-structured focus group discussion (10 groups, 2-9 smokers per group). One week after this session, participants were called to assess advertisement recall. Both quantitative and qualitative data indicated that highly emotional testimonial ads that featured a graphic portrayal of personal suffering from the consequences of smoking and visceral graphic ads were more effective. The ad on tobacco industry denormalization that focuses on the responsibility of the industry for smoking-related harms was considered ineffective because smokers perceived it as having little personal relevance. Humorous advertisements were evaluated as the least effective because they lacked strong emotional content linked to smoking consequences. Qualitative results suggest that advertisement characteristics are more important than the demographic characteristics of people featured in advertisements. Study findings provide preliminary evidence that testimonial ads that involve graphic and emotionally evocative portrayals of smoking-attributed diseases and visceral graphic ads may have the greater potential to motivate Taiwanese smokers to quit smoking.

    This study was conducted to identify the psychosocial factors associated with successful smoking cessation among ever-smokers aged 60 and older in the United States. Descriptive and multivariate analyses of the 2000 National Health Interview Survey (NHIS) were conducted. Controlling for sociodemographics and medical history of smoking-associated diseases, former smokers were less likely to have psychological distress (adjusted OR=0.71, 95% CI=0.58-0.88) and more likely to believe in the danger of second-hand smoke (adjusted OR=3.01, 95% CI=2.4-3.79) and the appropriateness of a smoking ban in indoor public places (adjusted OR=2.62, 95% CI=2.11-3.26). Having no regular source for care (adjusted OR=0.54, 95% CI=0.37-0.78) was an independent barrier to cessation, as were younger age, female, Hispanic race, being nonmarried and employed, and having lower income and education. This work contributes to a knowledge base for the development of interventions to maximize smoking cessation of elderly smokers. Findings suggest that strategies tailored to psychological distress and beliefs about smoking health harms and smoking restriction policies would aid in successful cessation. Specific measures reinforcing the importance of having a regular source for care may promote cessation. The extent to which these psychosocial factors affect elders' motivation to quit smoking remains to be explored.

    Background. Post-adolescent acne is an inflammatory disorder, whose cause is unknown. Contrasting data are available on correlation between acne and smoking habit. Objectives. To verify the frequency of clinically non-inflammatory (atypical) post-adolescent acne (APAA) among women, a possible correlation with cigarette smoking, possible differences in sebum composition in a group of female smokers with acne compared to healthy smokers and non-smokers. Method and results. 1046 randomly selected women (25–50-years-old) participated at the study. In 60 selected female subjects we analyzed sebum composition for α-tocopherol, squalene and squalene monohydroperoxide. We found a high prevalence of APAA among women (74.6%), a strong correlation with smoking habit (p < 0.0001), as well as an increase in the grade of sebum peroxidation (p < 0.05) with a reduction in vitamin E (p = 0.02), in the subjects with acne compared to the controls. Conclusions. Clinical evidence and experimental data showed a straight correlation between smoking habit and post-pubertal acne in which the clinically non-inflammatory type—APAA—is the most frequent. In the more severe cases we could consider APAA as a new entity (smoker’s acne). PMID:20436880

    Albert Einstein's biographers have not explained why he developed the abdominal aortic aneurysm that led to his death. Early conjectures proposed that it was caused by syphilis, without accurate evidence. The present article gives evidence to the contrary, and argues that the principal cause of Einstein's death was smoking.

    Regular smoking is the major risk factor for cardiovascular disease and cancers, and thus is one of the most preventable causes of morbidity and mortality worldwide. Intake of nicotine, its central nervous system effects, and its metabolism are regulated by biological pathways; some of these are well known, but others are not. Genetic studies offer a method for developing insights into the genes contributing to those pathways. In recent years, large genome-wide association study (GWAS) meta-analyses have consistently revealed that the strongest genetic contribution to smoking-related traits comes from variation in the nicotinic receptor subunit genes. Many other genes, including those coding for enzymes involved in nicotine metabolism, also have been implicated. However, the proportion of phenotypic variance explained by the identified genetic variants is very modest. This review intends to cover progress made in genetics and genetic epidemiology of smoking behavior in recent years, and focuses on studies revealing the nicotinic receptor gene cluster on chromosome 15q25. Evidence supporting the involvement of a novel pathway in the shared pathophysiology of nicotine dependence and schizophrenia is also briefly reviewed. A summary of the current knowledge on gene–environment interactions involved in smoking behavior is included. PMID:24778978

    The mainstay in smoking cessation is counselling in combination with varenicline, nicotine replacement therapy (NRT) or bupropion SR. Varenicline and combination of two NRTs is equally effective, while varenicline alone is more effective than either NRT or bupropion SR. NRT is extremely safe but cardiovascular and psychiatric adverse events with varenicline have been reported. These treatments have also been shown to be effective in patients with chronic obstructive pulmonary disease (COPD). A model study is the Lung Health Study from the USA. Findings from this study of 5,587 patients with mild COPD showed that repeated smoking cessation for a period of 5 yrs resulted in a quit rate of 37%. After 14.5 yrs the quitters had a higher lung function and a higher survival rate. A study with a new nicotine formulation, a mouth spray, showed high relative efficacy. As 5-10% of quitters use long-term NRT, we report the results of a study where varenicline compared with placebo increased the quit rate in long-term users of NRT. Smoking cessation is the most effective intervention in stopping the progression of COPD, as well as increasing survival and reducing morbidity. This is why smoking cessation should be the top priority in the treatment of COPD.

    The habit of smoking was well-known in Norway in the first half of the sixteenth century. Tobacco-smoking is seen in Norwegian paintings. In the nineteenth century, long and artistic pipes were used by men relaxing after a pleasant dinner. In self portraits of Christian Krohg and Edvard Munch we see them smoking pipes and cigarettes surrounded by smoke. In an exhibition of portraits of Norwegian Authors, ten out of seventy authors were portrayed with a pipe, a cigar or a cigarette. There are various interpretations of the use of smoking in art. A simple explanation is that this was an accepted part of life at that time. The authors may have believed that they concentrated better when they smoked and elegance may have been of importance for many of them. The symbolic significance of cigarette-smoking has been of great value in the marketing of tobacco-products.

    We investigated three potential predictors (educational attainment, prepregnancy smoking rate, and delay discounting [DD]) of spontaneous quitting among pregnant smokers. These predictors were examined alone and in combination with other potential predictors using study-intake assessments from controlled clinical trials examining the efficacy of financial incentives for smoking cessation and relapse prevention. Data from 349 pregnant women (231 continuing smokers and 118 spontaneous quitters) recruited from the greater Burlington, VT, area contributed to this secondary analysis, including psychiatric/sociodemographic characteristics, smoking characteristics, and performance on a computerized DD task. Educational attainment, smoking rate, and DD values were each significant predictors of spontaneous quitting in univariate analyses. A model examining those three predictors together retained educational attainment as a main effect and revealed a significant interaction of DD and smoking rate (i.e., DD was a significant predictor at lower but not higher smoking rates). A final model considering all potential predictors, included education, the interaction of DD and smoking rate, and five additional predictors (i.e., stress ratings, the belief that smoking during pregnancy will "greatly harm my baby," age of smoking initiation, marital status, and prior quit attempts during pregnancy). The study presented here contributes new knowledge on predictors of spontaneous quitting among pregnant smokers with substantive practical implications for reducing smoking during pregnancy.

    Harm caused by preventive programs may be physical, psychological, social or, if informed consent has not been obtained, ethical. Adverse effects of preventive screening programs may occur at any of the three levels of the "screening cascade", the screening procedure itself, the investigation of abnormal results of screening tests or the treatment of detected abnormalities or diseases. The greatest harm occurs at the second and third levels. Examples of procedures that may cause physical harm are venipuncture, mammography, colonoscopy, breast biopsy, transrectal ultrasonography, prostate biopsy, weight-reducing and cholesterol-lowering diets and radical prostatectomy. The psychological and social harm of preventive programs involves anticipated discomfort or perception of adverse effects of preventive interventions; unpleasant interactions with health care workers, time required for preventive programs, excessive overall awareness of health, anxiety over the results of a screening test implications of a positive screening test, consequences of being labelled as "sick" or "at risk," psychopathologic effects induced directly by preventive programs and, in the case of a false-negative test result, false assurance of disease-free status. Since the positive predictive value of screening tests in the general population is always low, most abnormal test results are "false-positive," these engender a great deal of psychological discuss among patients.

    The exposition to tobacco smoke is overall: in home, work and public places. For the examination of the presence and concentration of environmental tobacco smoke (ETS) in indoor environments the nicotine and respirable suspended particulates (RSP) are determined. A variety of biomarkers (nicotine, cotinine, thiocyanate, carboxyhemoglobin, protein and DNA adducts) are propose for measurement of exposure to tobacco smoke. The most popular is measurement of cotinine concentration in body fluids (blood, urine, saliva). Plasma cotinine concentration correlated to numbers of cigarettes smoked and to various biological effects of cigarette smoking and exposure to ETS. Other biomarkers as carboxyhemoglobin, thiocyanate, and amines and polycyclic aromatic hydrocarbons adduct can be also use.

    Chronic obstructive pulmonary disease (COPD) mortality and morbidity have increased significantly worldwide in recent decades. Although cigarette smoke is still considered the main risk factor for the development of the disease, estimates suggest that between 25% and 33% of COPD patients are non-smokers. Among the factors that may increase the risk of developing COPD, biomass smoke has been proposed as one of the most important, affecting especially women and children in developing countries. Despite the epidemiological evidence linking exposure to biomass smoke with adverse health effects, the specific cellular and molecular mechanisms by which this pollutant can be harmful for the respiratory and cardiovascular systems remain unclear. In this article we review the main pathogenic mechanisms proposed to date that make biomass smoke one of the major risk factors for COPD.

    This study investigated the association of inhalation injury (IHI) with smoking, alcohol and drug abuse in patients admitted to the Welsh Centre for Burns between 1995 and 2006. Common characteristics of these individuals were identified and contrasted with inhalation injury not associated with these social factors. Two hundred and fourteen patients were identified with inhalation injury. Ninety-two of these were associated with smoking, alcohol abuse and/or drug abuse. The proportion of IHI cases associated with smoking remained stable but IHI associated with alcohol and drug abuse increased dramatically over the course of the study and if current trends continue will increase further in future years. This study also showed that IHI associated with smoking alcohol and drug abuse were found to be largely caused by housefires and deliberate self-harm, and occurred between 22:00 and 05:59 h. These results were in sharp contrast with IHI not associated with these factors.

    The aim of this study was to assess the levels of secondhand smoke (SHS) exposure of men and women in public places in Kyrgyzstan. This cross-sectional study involved 10 bars and restaurants in Bishkek the capital city of Kyrgyzstan. Smoking was allowed in all establishments. Median (interquartile range) air nicotine concentrations were 6.82 (2.89, 8.86) microg/m(3). Employees were asked about their smoking history and exposure to SHS at work. Employees were exposed to SHS for mean (SD) 13.5 (3.6) hours a day and 5.8 (1.4) days a week. Women were exposed to more hours of SHS at work compared to men. Hospitality workers are exposed to excessive amounts of SHS from customers. Legislation to ban smoking in public places including bars and restaurants is urgently needed to protect workers and patrons from the harmful effects of SHS.

    - Two recent societal cost-benefit analyses have documented the costs of smoking and the cost-effectiveness of preventing smoking.- Smoking costs the Netherlands society EUR 33 billion per year.- The majority of this is the monetary value of health loss; these are "soft" euros that cannot be re-spent.- There is not a great deal of difference between costs and benefits when expressed in "hard" euros, which means that there is no clear business case for anti-smoking policy.- The greatest benefit of discouraging smoking is improved health for the individual and increased productivity for the business sector; however, the benefits cannot be easily realised, because even in the most favourable scenario the number of smokers will decrease slowly.- Excise duties seem to offer the most promising avenue for combating smoking. The benefits of anti-smoking policy, therefore, consist mainly of tax revenues for the government.- Stringent policy is required to transform tax revenues into health gains.

    Smoking continues to be the leading cause of preventable death in the USA, despite the vast and widely publicized knowledge about the negative health effects of tobacco smoking. Data show that smoking cessation is often accompanied by weight gain and an improvement in insulin sensitivity over time. However, paradoxically, post-cessation-related obesity might contribute to insulin resistance. Furthermore, post-cessation weight gain is reportedly the number one reason why smokers, especially women, fail to initiate smoking cessation or relapse after initiating smoking cessation. In this Review, we discuss the metabolic effects of stopping smoking and highlight future considerations for smoking cessation programs and therapies to be designed with an emphasis on reducing post-cessation weight gain.

    The five most commonly recognized Harmful Algal Bloom related illnesses include Ciguatera poisoning, Paralytic Shellfish poisoning, Neurotoxin Shellfish poisoning, Diarrheic Shellfish Poisoning and Amnesic Shellfish poisoning. Although they are each the product of different toxins, toxin assemblages or HAB precursors these clinical syndromes have much in common. Exposure occurs through the consumption of fish or shellfish; routine clinical tests are not available for diagnosis; there is no known antidote for exposure; and the risk of these illnesses can negatively impact local fishing and tourism industries. Thus, illness prevention is of paramount importance to minimize human and public health risks. To accomplish this, close communication and collaboration is needed among HAB scientists, public health researchers and local, state and tribal health departments at academic, community outreach, and policy levels.

    Age increases vulnerability, commonly accompanied by greater reliance on others and susceptibility to maltreatment. Physiologic processes become less resilient; the potential for harm from medical care increases. Awareness of frailty, functional, social, and potential maltreatment issues enables early referrals to help the patient maintain her independence. Health issues that may impede both gynecologic care and self-sufficiency include sensory deficits, physical disability, and cognitive impairment. Speaking slowly and providing contextual information enhance patient comprehension. Cancer screening depends on life expectancy. Osteoporosis treatment requires managing fall risk. Gynecologic symptoms more likely have multiple contributing factors than one etiology. Incontinence is a particularly complex issue, but invariably includes bladder diary assessment and pelvic floor muscle training. Function and frailty measures best predict perioperative morbidity. Communication with the patient, her family, other providers, and health care organizations is an important frontier in avoiding errors and adverse outcomes.

    Radiation therapy confers enormous benefits that must be balanced against the possibilities for harm including late toxicity in normal tissues and radiation-induced second malignancies. A small percentage of patients experience severe late complications. The question is, do these late sequelae occur randomly, or are they confined to individuals who are genetically predisposed to radiosensitivity. Experiments with knockout mice and with patients demonstrate that individuals heterozygous for a number of genes appear to be radiosensitive. If radiosensitive patients were identified prospectively by genetic analysis, they could be spared the trauma of late sequelae. Several large studies have shown a statistically significant excess of radiation-induced malignancies in radiotherapy patients. Most second cancers are carcinomas, developing in the lining cells of the body often remote from the treatment site. Radiation-induced sarcomas appear only in the heavily irradiated areas. These are small in number but appear with a very high relative risk.

    The demand for organs prompted the first use of elective ventilation in the UK in the 1990s. Recently the shortfall in supply of organs has once again prompted calls for elective ventilation to be instituted even in patients who are not brain dead. This paper proposes that the term 'elective' ventilation is a misnomer and the term non-therapeutic ventilation (NTV) should be used instead. It is further argued that the practice of NTV in cases of severe stroke is unethical and has the potential of causing a variety of harms to the patient, their relatives, and the healthcare professionals working in transplant teams and this may result in a backlash of reductions in the number of organ donations.

    Background To describe how frequently harm is reported in the abstract of high impact factor medical journals. Methods Design and population: We carried out a blinded structured review of a random sample of 363 Randomised Controlled Trials (RCTs) carried out on human beings, and published in high impact factor medical journals in 2003. Main endpoint: 1) Proportion of articles reporting harm in the abstract; and 2) Proportion of articles that reported harm in the abstract when harm was reported in the main body of the article. Analysis: Corrected Prevalence Ratio (cPR) and its exact confidence interval were calculated. Non-conditional logistic regression was used. Results 363 articles and 407 possible comparisons were studied. Overall, harm was reported in 135 abstracts [37.2% (CI95%:32.2 to 42.4)]. Harm was reported in the main text of 243 articles [66.9% (CI95%: 61.8 to 71.8)] and was statistically significant in 54 articles [14.9% (CI95%: 11.4 to 19.0)]. Among the 243 articles that mentioned harm in the text, 130 articles [53.5% (CI95% 47.0 to 59.9)] reported harm in the abstract; a figure that rose to 75.9% (CI95%: 62.4 to 86.5) when the harm reported in the text was statistically significant. Harm in the abstract was more likely to be reported when statistically significant harm was reported in the main body of the article [cPR = 1.70 (CI95% 1.47 to 1.92)] and when drug companies (not public institutions) funded the RCTs [cPR = 1.29 (CI95% 1.03 to 1.67)]. Conclusion Abstracts published in high impact factor medical journals underreport harm, even when harm is reported in the main body of the article. PMID:18371200

  5. Geoengineering, Climate Harm, and Business as Usual

    2014-12-01

    We define geoengineering (GE) as the intentional use of technology to change the planet's climate. Many people believe GE is different in kind rather than degree from any other organized activity in human history. In fact, humans caused changes in the planet's climate long before the industrial age, and all organisms engineer their environments directly or indirectly. The relevant difference between this cumulative and generally inadvertent activity and GE is the presence of intention. Now that science has revealed the extent to which humans can change the climate, however, even the continuance of Business as Usual (BAU) is, in effect, a form of intentional GE, albeit one that will cause significant climate harm, defined as effects such as sea level rise that will impact human well-being. But as with all forms of engineering, the devil is in the details: what forms of GE should be tried first? Some methods, such as large-scale afforestation, are low risk but have long-term payoffs; others, such as aerosol injection into the stratosphere, could help buy time in a warming crisis but have unknown side-effects and little long-term future. Climate change is a world-wide, inter-generational tragedy of the commons. Rational choice theory, the spatial and temporal extension of the problem, poorly fitted moral frameworks, and political maneuvering are all factors that inhibit solutions to the climate tragedy of the commons. The longer that such factors are allowed to dominate decision-making (or the lack thereof) the more likely it is that humanity will be forced to resort to riskier and more drastic forms of GE. We argue that this fact brings an additional measure of urgency to the search for ways to engineer the climate differently so as to avoid climate harm in the most lasting and least risky way.

    The benzodiazepines (BZDs) are anxiolytics, hypnotics, anticonvulsants, muscle-relaxants and induce anaesthesia. Adverse effects comprise sedation subjectively and cognitive and psychomotor impairment objectively. Complex skills such as driving can be compromised. Paradoxical excitement can have forensic implications. Long term use beyond the licensed durations is common but both efficacy and adverse effects associated with this have been poorly documented. Withdrawal and dependence have excited particular concern, and even polemic. Perhaps a third of long term (beyond 6 months) users experience symptoms and signs on attempting to withdraw – anxiety, insomnia, muscle spasms and tension and perceptual hypersensitivity. Uncommonly, fits or a psychosis may supervene. The patterns following withdrawal vary widely. The usual method of withdrawal is slow tapering but it may not obviate the problems completely. BZDs are also drugs of abuse either on their own or in conjunction with opioids and stimulants. Claims have been made that the use of BZDs is associated with increased mortality. This is a concern in view of the widespread usage of these drugs, particularly in the elderly. All of these factors impinge on the risk : benefit ratio and the severity of the indications. Harm reduction should focus on choice of alternative treatments both psychological and pharmacological. Guidelines emphasise that BZDs are not drugs of first choice and should only be used short term. Schedules are available to educate about methods of withdrawal in current users, emphasising the slow rate of taper. General principles of harm minimization in the addiction field are appropriate to BZD abuse. PMID:22882333

    2013-05-01

    We propose a novel multistage smoke detection algorithm based on inherent optical characteristics such as diffusion, color, and texture of smoke. Moving regions in a video frame are detected by an approximate median background subtraction method using the diffusion behavior of smoke. These moving regions are segmented by a fuzzy C-means (FCM) clustering algorithm that uses the hue and saturation components of moving pixels in the hue-saturation-intensity color space. A decision rule is used to select candidate smoke regions from smoke-colored FCM clusters. An object tracking approach is employed in the candidate smoke region to detect candidate smoke objects in the video frame, and image texture parameters are extracted from these objects using a gray level co-occurrence matrix (GLCM). The thirteen GLCM features are selected to constitute the feature vector by applying principal components analysis, resulting in high-accuracy smoke detection. Finally, a back propagation neural network is utilized as a classifier to discriminate smoke and nonsmoke using the selected feature vector. Experimental results using a standard experimental dataset of video clips demonstrate that the proposed approach outperforms state-of-the-art smoke detection approaches in terms of accuracy, making real-life implementation feasible.

    Second-hand smoke (SHS) and tobacco smoke products (TSPs) are recognised global risks for human health. The present article reviews the causal role of SHS and TSPs for respiratory disorders in infants and young children. Several studies have shown an effect of TSPs exposure during pregnancy upon lung function in the newborn infant and of SHS on symptoms and lung function after birth. From 1997 to 1999 a set of systematic reviews concerning the relationship between second-hand exposure to tobacco smoke and respiratory health in children was published in Thorax by Cook and Strachan, covering hundreds of published papers. The evidence for a causal relationship between SHS exposure and asthmatic symptoms and reduced lung function is quite strong, whereas the evidence related to the development of allergy is much weaker. There is recent evidence relating to an interaction between TSP exposure and genetic ploymorphisms, demonstrating that certain individuals are more susceptible to the effect of TSP exposure on lung health. In the present review, an overview is given for the effects of TSP exposure and SHS upon lung health in children, with a focus on infants and young children. There is a need for intervention to reduce TSP exposure in young children, by educating parents and adolescents about the health effects of TSP exposure. Recent legislation in many European countries related to smoking in the workplace is of great importance for exposure during pregnancy. Studies are needed to identify possible critical periods for TSPs to induce harmful effects upon lung health in young children and on environment-gene interactions in order to prevent harm.

    Despite a reduction in Federal regulatory activity, research concerned with flame retardancy and smoke suppression in the private sector appears to be increasing. This trend seem related to the increased utilization of plastics for end uses which traditionally have employed metal or wood products. As a result, new markets have appeared for thermally stable and fire resistance thermoplastic materials, and this in turn has spurred research and development activity. In addition, public awareness of the dangers associated with fire has increased as a result of several highly publicized hotel and restaurant fires within the past two years. The consumers recognition of flammability characteristics as important materials property considerations has increased. The current status of fire and smoke retardant chemistry and research are summarized.

    In recent years psychologists have been increasingly concerned about potentially harmful therapy, yet this recent discourse has not addressed issues that have long been voiced by the multicultural counseling and psychotherapy movement. We aim to begin to bring these seemingly disparate discourses of harm into greater conversation with one another, in the service of placing the discipline on a firmer foothold in its considerations of potentially harmful therapy. After reviewing the two discourses and exploring reasons for their divergence, we argue that they operate according to differing assumptions pertaining to the sources, objects, and scope of harm. We then argue that these differences reveal the discipline’s need to better appreciate that harm is a social construct, that psychotherapy may be inherently ethnocentric, and that strategies for collecting evidence of harm should be integrated with a social justice agenda.

    Smoking bans are gaining widespread support in the European Union and other countries. The vast majority of these bans are partial bans given that smoking is still permitted in certain places. This article investigates the role of partial smoking bans in coping with externalities caused by the secondhand smoking problem. Although it is widely known that Pigouvian taxation is superior to a perfect ban, this result does not necessarily carry over to a partial ban because taxes cannot (easily) be differentiated according to location. We show that under an easy and intuitive condition, (1) enacting a partial smoking ban alone always improves social welfare (a) in an unregulated society and (b) even in a regulated society if externalities can be eliminated, and (2) it is ensured that a combination of Pigouvian tax and a partial smoking ban leads to a higher social optimum than implementing corrective Pigouvian taxation alone.

    In this work, the volatile profiles of smoked and non-smoked Iranian rice were identified, and their relative abundance was calculated and compared. Headspace solid-phase microextraction together with gas chromatography-mass spectrometry (SPME-GC-MS) were used to extract and identify the volatile compounds. The main groups of volatiles in Iranian rice were aldehydes, ketones, phenol derivatives, furans, linear hydrocarbons, esters and terpenes. The chemical family aldehydes was the most abundant one in the profile of non-smoked rice, while phenol derivatives and furans predominated in smoked samples. This study is the first one reporting comparative data of volatile compounds between smoked and non-smoked Iranian rice. PMID:28231176

    As a determining factor in various diseases and the leading known cause of preventable mortality and morbidity, tobacco use is the number one public health problem in developed countries. Facing this health problem requires authorities and health professionals to promote, via specific programs, health campaigns that improve patients’ access to smoking cessation services. Pharmaceutical care has a number of specific characteristics that enable the pharmacist, as a health professional, to play an active role in dealing with smoking and deliver positive smoking cessation interventions. The objectives of the study were to assess the efficacy of a smoking cessation campaign carried out at a pharmaceutical care center and to evaluate the effects of pharmaceutical care on patients who decide to try to stop smoking. The methodology was an open, analytical, pre–post intervention, quasi-experimental clinical study performed with one patient cohort. The results of the study were that the promotional campaign for the smoking cessation program increased the number of patients from one to 22, and after 12 months into the study, 43.48% of the total number of patients achieved total smoking cessation. We can conclude that advertising of a smoking cessation program in a pharmacy increases the number of patients who use the pharmacy’s smoking cessation services, and pharmaceutical care is an effective means of achieving smoking cessation.

    Research supports an association between impulsivity and self-harm, yet inconsistencies in methodology across studies have complicated understanding of this relationship. This systematic review examines the association between impulsivity and self-harm in community-based adolescents aged 11-25 years and aims to integrate findings according to differing concepts and methods. Electronic searches of EMBASE, MEDLINE, PsychINFO, CINAHL, PubMed and The Cochrane Library, and manual searches of reference lists of relevant reviews identified 4496 articles published up to July 2015, of which 28 met inclusion criteria. Twenty-four of the studies reported an association between broadly specified impulsivity and self-harm. However, findings varied according to the conception and measurement of impulsivity and the precision with which self-harm behaviours were specified. Specifically, lifetime non-suicidal self-injury was most consistently associated with mood-based impulsivity-related traits. However, cognitive facets of impulsivity (relating to difficulties maintaining focus or acting without forethought) differentiated current self-harm from past self-harm. These facets also distinguished those with thoughts of self-harm (ideation) from those who acted on thoughts (enaction). The findings suggested that mood-based impulsivity is related to the initiation of self-harm, while cognitive facets of impulsivity are associated with the maintenance of self-harm. In addition, behavioural impulsivity is most relevant to self-harm under conditions of negative affect. Collectively, the findings indicate that distinct impulsivity facets confer unique risks across the life-course of self-harm. From a clinical perspective, the review suggests that interventions focusing on reducing rash reactivity to emotions or improving self-regulation and decision making may offer most benefit in supporting those who self-harm.

  17. Smoke knows no boundaries: legal strategies for environmental tobacco smoke incursions into the home within multi-unit residential dwellings

    Kline, R.

    2000-01-01

    OBJECTIVE—To describe legal theories that non-smoking residents of multiple occupancy buildings may employ when affected by environmental tobacco smoke (ETS) from neighbouring units.
DESIGN—Legal research was conducted in several US states. Research was performed among statutes and regulations. State health regulations were examined as well as common law claims of nuisance, warranties of habitability, and the right of quiet enjoyment.
RESULTS—Through the use of state regulations, such as a sanitary code, several states provide general language for protecting the health of residents in multi-unit buildings. State law also supports more traditional claims of nuisance, warranties of habitability, and the right of quiet enjoyment.
CONCLUSIONS—The use of state regulations has the potential to provide an effective, existing vehicle for resolution of ETS incursion problems. The general health protection language of the regulations, in conjunction with the latest evidence of the harmful effects of ETS, gives state agencies authority to regulate environmental tobacco smoke incursions among apartments in multi-unit dwellings. Where state regulations are not available, other common law legal remedies may be available.

  18. 'It's about the smoke, not the smoker': messages that motivate rural communities to support smoke-free policies.

    Rural residents are exposed to sophisticated tobacco advertising and tobacco growing represents an economic mainstay in many rural communities. There is a need for effective health messages to counter the pro-tobacco culture in these communities. To determine relevant cultural themes and key message features that affect receptivity to pro-health advertisements among rural residents, 11 exploratory focus groups and surveys with community advocates (N = 82) in three rural Kentucky counties were conducted. Participants reviewed and rated a collection of print media advertisements and branding materials used by rural communities to promote smoke-free policies. Findings reveal that negative emotional tone, loss framing, appeals to religiosity, and shifting focus away from smokers are effective strategies with rural audiences. Potential pitfalls were identified. Attacks on smokers may not be a useful strategy. Health risk messages reinforced beliefs of secondhand smoke harm but some argued that the messages needed to appeal to smokers and emphasize health hazards to smokers, rather than to non-smokers only. Messages describing ineffectiveness of smoking sections were understood but participants felt they were only relevant for restaurants and not all public spaces. Emphasis on religiosity and social norms shows promise as a culturally sensitive approach to promoting smoke-free environments in rural communities.

    The Hand Arm Risk Assessment Method (HARM 1.0) has been developed for occupational health officers to perform risk assessments of developing arm, neck or shoulder pain during hand arm tasks. The tool can also help in finding solutions for risk reduction and estimating their effect on the risk level. In this paper the status of affairs and the practical application of HARM is described. The usage of HARM is explained and illustrated with the risk assessment of a specific hand arm task. In addition, the experiences with the application of HARM by a stone factory in The Netherlands are described.

  1. Self-harm to preferentially harm the pathogens within: non-specific stressors in innate immunity

    PubMed Central

    2016-01-01

    Therapies with increasing specificity against pathogens follow the immune system's evolutionary course in maximizing host defence while minimizing self-harm. Nevertheless, even completely non-specific stressors, such as reactive molecular species, heat, nutrient and oxygen deprivation, and acidity can be used to preferentially harm pathogens. Strategic use of non-specific stressors requires exploiting differences in stress vulnerability between pathogens and hosts. Two basic vulnerabilities of pathogens are: (i) the inherent vulnerability to stress of growth and replication (more immediately crucial for pathogens than for host cells) and (ii) the degree of pathogen localization, permitting the host's use of locally and regionally intense stress. Each of the various types of non-specific stressors is present during severe infections at all levels of localization: (i) ultra-locally within phagolysosomes, (ii) locally at the infected site, (iii) regionally around the infected site and (iv) systemically as part of the acute-phase response. We propose that hosts strategically use a coordinated system of non-specific stressors at local, regional and systemic levels to preferentially harm the pathogens within. With the rising concern over emergence of resistance to specific therapies, we suggest more scrutiny of strategies using less specific therapies in pathogen control. Hosts' active use of multiple non-specific stressors is likely an evolutionarily basic defence whose retention underlies and supplements the well-recognized immune defences that directly target pathogens.

    The Hayman fire, situated about 65 kilometers southwest of Denver, Colorado, is the largest fire ever recorded in that state. The amount and distribution of smoke from the Hayman fire and from the Ponil Complex fires south of the New Mexico-Colorado border are portrayed in these views from the Multi-angle Imaging SpectroRadiometer (MISR). The images were captured on June 9, 2002, on the second day of the Hayman fire, when only about 13 percent of the total 137,000 acres eventually consumed had been scorched.

    The image at top-left was acquired by MISR's most oblique (70-degree) forward-viewing camera, and the view at bottom-left was captured by MISR's 26-degree forward-viewing camera. Both left-hand panels are 'false color' views, utilizing near-infrared, red, and blue spectral bands displayed as red, green and blue respectively. With this spectral combination, highly vegetated areas appear red. At top right is a map of aerosol optical depth. This map utilizes the capability of the oblique view angles to measure the abundance of particles in the atmosphere. Haze distributed across the eastern part of the state is indicated by a large number of green pixels, and areas where no retrieval occurred are shown in dark grey. The more oblique perspective utilized within the top panels enhances the appearance of smoke and reveals the haze. In the lower left-hand panel the view is closer to nadir (downward-looking). Here the smoke plumes appear more compact and the haze across eastern Colorado is not detected. The lower right-hand panel is a stereoscopically derived height field that echoes the compact shape of the smoke plumes in the near-nadir image. Results indicate that the smoke plumes reached altitudes of a few kilometers above the surface terrain, or about the same height as the small clouds that appear orange along the bottom edge to the left of center.

    Public health efforts to reduce the harms related to tobacco use currently include a significant emphasis on anti-smoking media campaigns. This paper provides (a) data on the overall extent of exposure to anti-smoking media among American youth from 1997 to 2001, (b) an appraisal of general youth reactions to such advertising, and (c) an examination of how exposure levels and reactions vary by socio-demographic characteristics. Data were obtained from the Monitoring the Future study, an ongoing nationwide study of youth. Data were collected each year from nationally representative separate and nonoverlapping school samples of 8th, 10th, and 12th grade students (N = 29,724; 24,639; and 12,138, respectively). Self-reported levels of recalled exposure to both electronic and print anti-smoking advertising were measured, as well as the judged impact and perceived exaggeration of such advertising. Data indicate that significant increases in overall exposure to anti-smoking advertising occurred over the study time period. These increases were associated with (a) increases in the self-reported likelihood that anti-smoking advertising diminished the probability of individual smoking behaviors, and (b) increases in the perceived level to which anti-smoking advertising exaggerates the risks associated with smoking. Further, these trends were significantly associated with various characteristics-most notably, ethnicity, smoking behaviors, and residence in a state with an ongoing tobacco-control program having a media component.

    2012-01-01

    Idiopathic pulmonary fibrosis (IPF) is a disease of unknown etiology with considerable morbidity and mortality. Cigarette smoking is one of the most recognized risk factors for development of IPF. Furthermore, recent work suggests that smoking may have a detrimental effect on survival of patients with IPF. The mechanism by which smoking may contribute to the pathogenesis of IPF is largely unknown. However, accumulating evidence suggests that increased oxidative stress might promote disease progression in IPF patients who are current and former smokers. In this review, potential mechanisms by which cigarette smoking affects IPF, the effects of cigarette smoking on accelerated loss of lung function in patients with IPF, key genetic studies evaluating the potential candidate genes and gene-environment (smoking) interaction, diagnosis, and treatment with emphasis on recently closed and ongoing clinical trials are presented.

    Years ago, the tobacco leaf offered its users many social and ceremonial benefits. But today, throughout the world, the manufactured cigarette wreaks biological havoc. Clinically, physicians can make a small, but significant, contribution to their patients' stopping smoking. Family physicians who want to offer systematic aid to their smoking patients should assess the amount of time and energy they are willing to invest in patients' smoking and the probable rewards of such efforts. Behavioural change comprises four stages: a pre-motivational phase, a motivational phase, a behavioural-change phase, and a maintenance phase. Anyone who has ever smoked belongs to one of these phases and should be treated accordingly. Paradoxically, the physician should support consonant smoking (the patient freely choosing to smoke) except when the smoker is actively engaged in changing behaviour. PMID:21248907

  7. Smoking outside: the effect of the Irish workplace smoking ban on smoking prevalence among the employed.

    PubMed

    Savage, Michael

    2014-10-01

    In March 2004, Ireland became the first country to introduce a nationwide workplace smoking ban. The primary aim of the ban was to reduce people's exposure to second-hand smoke. A 95% compliance rate among employers suggests this aim was achieved. By prohibiting smoking in the majority of indoor working places, an effect of the ban was to increase the non-monetary cost of smoking. The aim of this paper is to examine whether the extra non-monetary cost of smoking was concentrated on the employed. A difference-in-differences approach is used to measure changes in smoking behaviour among the employed relative to the non-working population following the introduction of the workplace smoking ban. The research finds that the workplace smoking ban did not induce a greater reduction in smoking prevalence among the employed population compared with the non-working population. In fact, the evidence suggests a significantly larger decrease in smoking prevalence among the non-workers relative to the employed. Changes in the real price of cigarettes and changes in attitudes to risk are discussed as possible causes for the pattern observed.

    The tobacco industry has promoted certain cigarette products with claims that their use may be less harmful to the smoker as they purportedly deliver lower amounts of toxic chemicals compared to conventional cigarettes. This study was designed to compare the relative antigen presenting cellular toxicity of Eclipse, a presumed reduced exposure product (PREP) cigarette, when compared with the reference research 3R4F cigarettes (Kentucky University). Utilizing a murine macrophage cell line, murine bone marrow derived dendritic cells (DCs) and human monocyte-derived DCs incubated with extracts generated from Eclipse and Kentucky reference 3R4F cigarettes, we determined the relative toxic effects of the different cigarette smoke extracts on cellular viability, oxidative stress, T-helper-1 (Th-1) polarizing cytokine production and general gene expression. Eclipse and 3R4F cigarette smoke extracts induced equivalent oxidatively-mediated cellular heme oxygenase-1 (HO-1) protein levels in macrophages and DCs. Cellular viability determination demonstrated greater induction of cell death by apoptosis and necrosis by Eclipse extracts in DCs. The production of the key Th-1 polarizing cytokine interleukin-12 (IL-12) by activated DCs or macrophages was suppressed to an equivalent or greater extent by Eclipse extracts. Microarray studies performed on bone marrow derived murine DCs incubated with Eclispe or 3R4F cigarette extracts showed identical genotoxic profiles. These studies imply that presumed reduced harm Eclipse cigarettes induce equivalent or greater antigen presenting cell dysfunction relative to 3R4F cigarettes and illustrate the importance of independent validation and testing of similar products claimed to be associated with reduced toxicity relative to other cigarettes.

    2014-01-01

    Although the environmentally harmful effects of widespread dichlorodiphenyltrichloroethane (DDT) use became well-known following Rachel Carson’s Silent Spring (1962), its human health effects have more recently become clearer. A ban on the use of DDT has been in place for over 30 years, but recently DDT has been used for malaria control in areas such as Africa. Recent work shows that DDT has transgenerational effects in progeny and generations never directly exposed to DDT. These effects have health implications for individuals who are not able to have any voice in the decision to use the pesticide. The transgenerational effects of DDT are considered in light of some widely accepted ethical principles. We argue that this reframes the decision to use DDT, requiring us to incorporate new considerations, and new kinds of decision making, into the deliberative process that determines its ongoing use. Ethical considerations for intergenerational environmental justice are presented that include concern and respect for autonomy, nonmaleficence, and justice. Here, we offer a characterization of the kinds of ethical considerations that must be taken into account in any satisfactory decisions to use DDT. PMID:25086599

  16. Optimal redesign study of the harm wing

    1984-01-01

    The purpose of this project was to investigate the use of optimization techniques to improve the flutter margins of the HARM AGM-88A wing. The missile has four cruciform wings, located near mid-fuselage, that are actuated in pairs symmetrically and antisymmetrically to provide pitch, yaw, and roll control. The wings have a solid stainless steel forward section and a stainless steel crushed-honeycomb aft section. The wing restraint stiffness is dependent upon wing pitch amplitude and varies from a low value near neutral pitch attitude to a much higher value at off-neutral pitch attitudes, where aerodynamic loads lock out any free play in the control system. The most critical condition for flutter is the low-stiffness condition in which the wings are moved symmetrically. Although a tendency toward limit-cycle flutter is controlled in the current design by controller logic, wing redesign to improve this situation is attractive because it can be accomplished as a retrofit. In view of the exploratory nature of the study, it was decided to apply the optimization to a wing-only model, validated by comparison with results obtained by Texas Instruments (TI). Any wing designs that looked promising were to be evaluated at TI with more complicated models, including body modes. The optimization work was performed by McIntosh Structural Dynamics, Inc. (MSD) under a contract from TI.

  17. Is Excess Calcium Harmful to Health?

    2010-01-01

    Most current guidelines recommend that older adults and the elderly strive for a total calcium intake (diet and supplements) of 1,000 to 1,300 mg/day to prevent osteoporosis and fractures. Traditionally, calcium supplements have been considered safe, effective and well tolerated, but their safety has recently been questioned due to potential adverse effects on vascular disease which may increase mortality. For example, the findings from a meta-analysis of randomized controlled trials (currently published in abstract form only) revealed that the use of calcium supplements was associated with an ~30% increased risk of myocardial infarction. If high levels of calcium are harmful to health, this may alter current public health recommendations with regard to the use of calcium supplements for preventing osteoporosis. In this review, we provide an overview of the latest information from human observational and prospective studies, randomized controlled trials and meta-analyses related to the effects of calcium supplementation on vascular disease and related risk factors, including blood pressure, lipid and lipoprotein levels and vascular calcification.

  20. Genetic Transmission of Disease: A Legal Harm?

    PubMed

    Stanton, Catherine

    2016-09-01

    This paper considers whether existing law could potentially be used to criminalize the transmission of genetic disease. The paper argues that even if an offence could be made out, the criminal law should not be involved in this context for many reasons, including the need to protect reproductive liberty and pregnant women's rights. The paper also examines whether there might be scope for civil claims between reproductive partners for a 'failure to warn' of potential genetic harm and argues there are strong policy grounds for resisting such claims. If such a duty were to exist, there might, in the future, be scope for a child to bring a claim under the Congenital Disabilities (Civil Liability Act) 1976. Such a claim could be for the failure by the child's father to warn her mother, which in turn led to the loss of opportunity to have treatment in utero which could have prevented the disability. It is suggested that the same arguments which supported granting maternal immunity under the Act would also support paternal immunity and that, therefore the issue of the lack of paternal immunity under the Act should be revisited.

  1. Energy drinks and adolescents: what's the harm?

    PubMed

    Harris, Jennifer L; Munsell, Christina R

    2015-04-01

    Concerns about potential dangers from energy drink consumption by youth have been raised by health experts, whereas energy drink manufacturers claim these products are safe and suitable for marketing to teens. This review summarizes the evidence used to support both sides of the debate. Unlike most beverage categories, sales of energy drinks and other highly caffeinated products continue to grow, and marketing is often targeted to youth under the age of 18 years. These products pose a risk of caffeine toxicity when consumed by some young people, and there is evidence of other troubling physiological and behavioral effects associated with their consumption by youth. The US Food and Drug Administration has indicated it will reexamine the safety of caffeine in the food supply; however, more research is needed to better understand youth consumption of energy drinks and caffeine in general, as well as the long-term effects on health. Meanwhile, policymakers and physician groups have called on energy drink manufacturers to take voluntary action to reduce the potential harm of their products, including placing restrictions on marketing to youth under the age of 18 years. Additional regulatory and legislative options are also being discussed.

    Problems experienced during quitting smoking, particularly withdrawal symptoms, make giving up difficult. In this study the description of the complaints arising in individuals quitting smoking thus acts as a guide for health professional who dealt with smoking cessation. Data belonging to 194 patients applying to the smoking cessation clinic and quitting smoking were analysed. Behavioural counselling and nicotine support therapy are administered in the smoking cessation programme. Patients are followed up for at least two years after quitting cigarettes, and their complaints are determined. One hundred and two (52.6%) of the 194 patients quitting smoking had various complaints. One of the most frequently experienced problems was weight gain. According to patients' statements, an average weight gain of 6.8 +/- 3.8 kg, minimum 1 kg maximum 16 kg, occurred. Seventeen (8.7%) patients complain of increased appetite. Those with increased appetite gained the most weight, to a significant extent (p= 0.001). In terms of average weight gain, those with increased appetite gained 4.6 +/- 2.3 kg, while those without increased appetite gained 7.3 +/- 3.9 kg, and the difference was significant (p= 0.033). Thirty-eight (19.6%) patients complain of lesions in the mouth, gums or tongue. Twelve (6.1%) patients had complaints of tension, restlessness, nervousness or sleeplessness, 9 (4.6%) of a desire to smoke, 9 (4.6%) of headache, 8 (4.1%) of constipation, and 7 (3.6%) of drowsiness, numbness or concentration impairment. Forty-five (44.1%) of the 102 patients with smoking cessation related complaints and 57 (62%) of 92 patients with no complaints recommenced smoking. Significantly fewer of those with complaints began smoking (p= 0.013). Counselling services to be provided by health personnel regarding the frequency, intensity and resolutions of problems experienced by those quitting smoking will increase cessation success and duration.

    Concentrations of the irritants formaldehyde and acrolein in side stream cigarette smoke plumes are up to three orders of magnitude above occupational limits, readily accounting for eye and nasal irritation. ''Low-tar'' cigarettes appear at least as irritating as other cigarettes. More than half the irritant is associated with the particulate phase of the smoke, permitting deposition throughout the entire respiratory tract and raising the issue of whether formaldehyde in smoke is associated with bronchial cancer.

  4. Defining and redefining harm reduction in the Lao context

    The response to drug use in Laos has focused on reducing opium supply (supply reduction) and rates of drug use (demand reduction). However, recently there is increased interest among government counterparts to discuss and develop broader responses to injecting drug use (IDU) including the introduction of harm reduction programs. The concept of harm reduction has just been introduced to Lao PDR and as yet there is no agreement on a definition of the concept. We highlight here a range of issues that remain controversial in Lao PDR in the HIV, drug use and harm reduction discourse, the definition of 'harm reduction' and related terms; and the scope of harm reduction. This was a qualitative study, consisting of in-depth interviews with 27 law enforcement and 8 health officers who work in the fields of HIV and/or drug control about their understanding of HIV related to drug use, and concepts of harm reduction. Content analysis was performed to identify the coding, categories and themes. We found that law enforcement officers in particular had limited understanding about harm reduction and the feasibility and appropriateness of harm reduction services in the Lao context. Harm reduction should be a core element of a public health response to HIV where drug use and IDU exists. Recommendations include the necessity of increasing the awareness of harm reduction among law enforcement officers and providing appropriate evidence to support the needs of harm reduction policy and programs. HIV prevention and treatment strategies should be integrated within existing social and cultural frameworks, working with the task force for HIV/IDU and other government counterparts. PMID:22769736

  6. The importance and limits of harm in identifying mental disorder.

    2013-11-01

    The In Review articles in this issue on normality and disorder by Dr Rachel Cooper and Dr Derek Bolton explore the importance of a value component of harm in the concept of mental disorder. They focus on the Diagnostic and Statistical Manual of Mental Disorder's clinical significance criterion, requiring that symptoms cause significant distress or role impairment, as the expression of the harm component. As Dr Bolton argues, harm in the form of distress or role impairment has always been intimately tied to the concept of disorder and treatment decisions; as Dr Cooper argues, without the harm requirement, any disliked anomaly may be labelled a disorder. Moreover, as Cooper argues, a harm requirement is not incompatible with a natural kinds approach to distinguishing among disorders or to a categorical approach to disorder; the lack of zones of rarity on the harm continuum does not preclude categorical underlying causal processes. However, neither paper systematically develops arguments regarding the other component of disorder, the requirement that the harm must be caused by underlying dysfunction. The dysfunction component distinguishes disorders from the many other negative conditions in life. Cooper's identification of dysfunction with symptom severity ignores the fact that normal suffering can be severe, and Bolton's attempt to encompass risk of harm within harm yields an implausibly expansive conception of disorder. While the harm component is essential, clarification of the dysfunction component of the concept of disorder, pursued in part 2 of this In Review in the December 2013 issue, is also essential to establishing a coherent and plausibly limited domain of psychiatric disorder within the broader arena of harmful conditions.

    We previously reported toxic metal concentrations in the mainstream smoke from 50 varieties of commercial cigarettes available in the USA using quadrupole inductively coupled plasma-mass spectrometry (ICP-MS). However, efforts to continue producing high quality data on select mainstream cigarette smoke constituents demand continued improvements in instrumentation and methodology and application of the methodology to cigarettes that differ in design or construction. Here we report a new application of 'triple quad'-ICP-MS instrumentation to analyze seven toxic metals in mainstream cigarette smoke from the Spectrum variable nicotine research cigarettes. The Spectrum cigarettes are available for research purposes in different configurations of low or conventional levels of nicotine, mentholated or nonmentholated, and tar delivery ranges described as 'low tar' or 'high tar'. Detailed characterizations of specific harmful or potentially harmful constituents delivered by these research cigarettes will help inform researchers using these cigarettes in exposure studies, cessation studies and studies related to nicotine addiction or compensation.

    'Smoke' is a flight definition investigation whose purpose is to characterize the smoke particulate from microgravity smoke sources to enable improved design of future space-craft smoke detectors. In the earliest missions (Mercury, Gemini and Apollo), the crew quarters were so cramped that it was considered reasonable that the astronauts would rapidly detect any fire. The Skylab module, however, included approximately 30 UV-sensing fire detectors. The Space Shuttle Orbiter has nine particle-ionization smoke detectors in the mid-deck and flight deck. The detectors for the US segments of the International Space Station (ISS) are laser-diode, forward-scattering, smoke detectors. Current plans for the ISS call for two detectors in the open area of the module, and detectors in racks that have cooling air-flow. Due to the complete absence of microgravity data, all three of these detector systems were designed based upon 1-g test data and experience. As planned mission durations and complexity increase and the volume of spacecraft increases, the need for and importance of effective, crew-independent, fire detection will grow significantly, necessitating more research into microgravity fire phenomena. In 1997 the Comparative Soot Diagnostics Experiment (CSD) flew in the Orbiter Middeck as a Glovebox payload. The CSD experiment was designed to produce small quantities of smoke from several sources to obtain particulate samples and to determine the response of the ISS and Orbiter smoke detectors to these sources. Marked differences in the performance of the detectors compared to their behavior in 1-g were observed. In extreme cases, the detector used in the orbiter was completely blind to easily visible smoke from sources that were readily detected in 1-g. It is hypothesized but as yet unverified that this performance difference was due to enhanced growth of liquid smoke droplets in low-g. These CSD results clearly demonstrate that spacecraft smoke detector design cannot be

  9. Familial influences on adolescent smoking.

    The family unit is the primary source of transmission of basic social, cultural, genetic, and biological factors that may underlie individual differences in smoking. Existing information on the role of familial factors in tobacco use is characterized by two separate, but somewhat overlapping, lines of research: genetic epidemiological studies and risk-factor research. The present paper summarizes and evaluates studies assessing the association between adolescent smoking and parent and sibling smoking behaviors. A review of 87 studies reveals that methods are limited by a lack of standardized instruments, failure to measure important confounding and mediating factors, reliance on cross-sectional designs and the use of inconsistent definitions of tobacco-related behavior and assessment procedures. Moreover, there are no systematic family studies of the acquisition and continuation of smoking that have employed contemporary methodological standards for examining familial aggregation of tobacco behaviors among adolescents. Findings across studies show weak and inconsistent associations between parent and adolescent smoking; inconsistent findings may be attributed to methodological issues or associated factors that may complicate the relation between parent and adolescent smoking. Sibling and peer smoking show greater associations with adolescent smoking. Suggestions for future research include contemporary family studies that delineate meaningful phenotypes of tobacco use and prospective work on the later stages of tobacco use and the timing of the influence and valence of parent and family factors. Integration of the risk factor approach within the family study design may enrich both approaches to elucidate familial influences on smoking.

    OBJECTIVE To analyze the prevalence and factors associated with smoking abstinence among patients who were treated in a reference unit for smoking cessation. METHODS This cross-sectional study examined the medical records of 532 patients treated in a reference unit for smoking cessation in Belém, PA, Northern Brazil, between January 2010 and June 2012. Sociodemographic variables and those related to smoking history and treatment were analyzed. Statistical significance was set at p < 0.05. RESULTS The mean age of the participants was 50 years; 57.0% of the patients were women. The mean tobacco load was 30 packs/year, and the mean smoking duration was approximately 32 years. Most patients remained in treatment for four months. The rate of smoking abstinence was 75.0%. Regression analysis indicated that maintenance therapy, absence of relapse triggers, and lower chemical dependence were significantly associated with smoking cessation. CONCLUSIONS The smoking abstinence rate observed was 75.0%. The cessation process was associated with several aspects, including the degree of chemical dependence, symptoms of withdrawal, and period of patient follow-up in a multidisciplinary treatment program. Studies of this nature contribute to the collection of consistent epidemiological data and are essential for the implementation of effective smoking prevention and cessation strategies.

    Surveillance of smoking behavior and study of consequences of smoking on the health of the French population, and particularly the female population, is a public health priority. The amount of tobacco consumed can be determined from sales figures and from surveys. Globally, tobacco sales increased through 1985. According to the available surveys, the proportion of regular smokers has varied little as smoking rate has decreased in men and increased in women. The decrease occurred in all age groups for men and increased only in the 25-49 year age group for women. Smoking is the cause of 60,000 deaths per year in France, 57,000 in the male population and 3,000 in the female population. Despite reinforced legislation (The Veil and Evin laws) which is unfortunately poorly applied, tobacco consumption has not decreased greatly. Funding levels for anti-smoking campaigns are totally insignificant compared with the efforts of the tobacco industry to promote their products. However, the beneficial health effect of stopping smoking is truly great since the risk depends much more on the duration of smoking than on the number of daily cigarettes. In addition, the delay between the cause and consequence is long, the consequences of the increase in tobacco smoking among young women over the last 20 years will not become visible until 20 to 40 years from now. One could wonder why so little effort has been put into anti-smoking campaigns despite the readily available data clearly warranting their promotion.

    71% of men and 20% of women of the lower socioeconomic class in Bangladesh are smokers. 83% of people in the lower classes smoke bidis rather than the more expensive cigarette. Bidis constitute a big cottage industry, employing 250,000 workers, including children, for a daily production of 250 million pieces. The bidis industry provides the Bangladesh government with US$23.3 million a year. Smoking control activities in Bangladesh are limited to a ban on smoking in cinemas and public places; articles and advertisements against smoking appear from time to time. In the Henan province of China 56% of the male population and 1% of the female population smoke. In Beijing 24% of boys under 18 are smokers. Chinese cigarettes have a high nicotine content. Smoking is banned in most public places and its health hazards are discussed by doctors at public meetings and in the mass media. 80% of the tobacco grown in India is consumed locally. Cigarette smoking predominates in the cities, especially among white-collar workers, while smoking of bidis predominates in other areas and among other social groups. Indian legislation makes health warnings compulsory on all cigarette packets, and smoking is prohibited in most public places. The importance of tobacco cultivation in India is a major obstacle to the implementation of an antismoking prgram. Sulpa is the most common form of smoking among 85% of men and 72% of women in rural Nepal; cigarette smoking is prevalent in Katmandu, where the prevalence of smoking is 65% among males and 14% among females. There is no specific legislation on control of smoking. Tobacco growing is an important source of revenue for the Pakistani government; annual production of tobacco is 70-80 million kg, of which 85% is consumed within the country. In 1980-81 total cigarette production reached 38,800 million pieces, a significant increase from 1970-71. Total cigarette consumption during the last 5 years has shown an average growth of 8% annually. The

  14. When You Smoke, They Smoke: Children's Rights and Opinions about Vehicular Smoking Bans

    International law guarantees every person the highest attainable standard of health, and this should include protection from the health risks of environmental tobacco smoke. As knowledge of these risks has increased, there has been an incremental expansion of smoking bans in public space. Since 2007, they have extended to the private space of the motor vehicle in an attempt to protect child passengers. This thesis aimed to understand the views and interests of children and youth on vehicular smoking bans, and the extent to which these have been sought after and considered in previous discussions of this policy initiative in Canada. A print media analysis found a lack of concern for children's perspectives. Rights, when considered, were generally those of adults. In focus groups, children discussed the unfairness of exposure to smoke in any space, but especially within the motor vehicle, and articulated a desire for increased participation in decision-making. Keywords: Smoking, smoking bans, rights, children's opinions, vehicles, Canada.

    Aims and Background: People living with mental disorders experience a disproportionately higher burden of tobacco-related disease than the general population. Long-term substitution with less harmful nicotine products could reduce the tobacco-related harm among this population. This study investigated the views and preferences of people with mental health disorders about different nicotine products and their use as long-term substitutes for cigarettes. Methods: Semi-structured focus group discussion followed by a brief questionnaire. The discussion transcripts were analysed for content and themes and quantitative data summarised with descriptive statistics. Results: Twenty-nine participants took part in four focus groups. Vaping devices were the most acceptable nicotine products discussed; however preferences for nicotine products were individual and varied along aesthetic, pragmatic, sensory and symbolic dimensions. The concept of tobacco harm reduction was unfamiliar to participants, however they generally agreed with the logic of replacing cigarettes with less harmful nicotine products. Barriers to activating tobacco harm reduction included the symbolism of smoking and quitting; the importance placed on health; the consumer appeal of alternatives; and cost implications. Discussion and Conclusions: Engaging this population in tobacco harm reduction options will require communication that challenges black and white thinking (a conceptual framework in which smoking cigarettes or quitting all nicotine are the only legitimate options) as in practice this serves to support the continuance of smoking. Consumers should be encouraged to trial a range of nicotine products to find the most acceptable alternative to smoking that reduces health harms. Providing incentives to switch to nicotine products could help overcome barriers to using less harmful nicotine products among mental health consumers. PMID:27886046

    We assessed 5- to 11-year-olds' (N = 76) judgments of straightforward moral transgressions (prototypical harm) as well as their evaluations of complex, hypothetical scenarios in which an actor transgresses in order to prevent injury (necessary harm). The nature of the actor's transgression (psychological or physical harm) varied across participants. Moral judgments and justifications, knowledge of the actor's psychological experience, and their associations were examined. At all ages, children negatively evaluated prototypical harm; judgments of necessary harm became increasingly more forgiving with age as justifications pertaining to the actor's harm decreased. References to the actor's positive actions and children's tendency to coordinate conflicting concerns increased with age, but only when evaluating psychological harm. Across conditions, older children viewed transgressors as holding increasingly more positive attitudes toward their own actions, and this was uniquely associated with more forgiving moral judgments and justifications of necessary but not prototypical harm. Findings are discussed in relation to the emergence of more flexible and nuanced moral evaluations during middle childhood.
