Drug abuse treatment programs typically recommend complete abstinence because of a fear that clients who stop use of one drug will substitute another. A within-subjects study investigated whether consumption of alcohol and other substances changes during marijuana abstinence. Twenty-eight daily marijuana users who were not trying to stop or reduce their marijuana consumption completed an 8-day baseline period in which they used marijuana and other drugs as usual, a 13-day marijuana abstinence period, and a 7-day return-to-baseline period. Participants provided self-report of substance use daily and submitted urine samples twice weekly to verify marijuana abstinence. A diagnosis of past alcohol abuse or dependence significantly moderated the alcohol increase from baseline to marijuana abstinence (p<0.01), such that individuals with this diagnosis significantly increased alcohol use (52% increase) but those without this history did not (3% increase). Increases in marijuana withdrawal discomfort scores and alcohol craving scores from baseline to marijuana abstinence significantly and positively correlated with increases in alcohol use. Increases in cigarettes, caffeine, and non-marijuana illicit drugs did not occur. This study provides empirical validation of drug substitution in a subgroup of daily marijuana users, but results need to be replicated in individuals who seek treatment for marijuana problems.

Introduction African American youth use marijuana at similar rates and tobacco at lower rates compared with white youth; however, in adulthood, tobacco use is similar. Tobacco and marijuana use are closely associated; differing initiation patterns may contribute to observed racial differences in tobacco prevalence by age. Therefore, it is important to assess tobacco and marijuana initiation patterns by race. Methods Data were obtained from 56,555 adults aged 18–25 who completed the 2005–2012 National Survey on Drug Use and Health. The analysis was restricted to those who reported ever use of marijuana and combustible tobacco (cigarettes and/or cigars). Three mutually exclusive categories of initiation patterns were evaluated: use of marijuana before tobacco; marijuana and tobacco at the same age; and tobacco before marijuana. Multivariable regression models were used to assess changes over time and compare these outcomes by race while controlling for sociodemographics, risk perceptions, and current substance use. Results In 2005, 26.6% of African American and 14.3% of white young adults used marijuana before tobacco, compared with 41.5% of African American and 24.0% of white young adults in 2012 (P < .001). Overall, African American young adults had greater odds of using marijuana before tobacco (AOR = 1.79; 95% CI: 1.67, 1.91) compared with whites. Conclusion African American young adults were more likely than whites to use marijuana before tobacco and both groups were increasingly likely to use marijuana before tobacco over time. A greater understanding of how marijuana initiation interacts with tobacco initiation could inform more effective tobacco and marijuana use prevention efforts. Implications Among ever users of combustible tobacco and marijuana, greater proportions of African American young adults used marijuana before tobacco or at the same age than their white counterparts. Moreover, both African Americans and whites were more likely to use

1990-03-01

The effects of marijuana smoke exposure on several measures of tobacco cigarette smoking behavior were examined. Eight healthy adult male volunteers, who smoked both tobacco and marijuana cigarettes, participated in residential studies, lasting 10 to 15 days, designed to measure the effects of marijuana smoke exposure on a range of behavioral variables. Tobacco cigarettes were available throughout the day (9:00 A.M. until midnight). Each day was divided into a private period (9:00 A.M. to 5:00 P.M.), during which subjects were socially isolated, and a social period (5:00 P.M. to midnight), during which subjects could interact. Under blind conditions, subjects smoked placebo and active marijuana cigarettes (0%, 1.3%, 2.3%, or 2.7% delta 9-tetrahydrocannabinol) four times daily (9:45 A.M., 1:30 P.M., 5:00 P.M. and 8:30 P.M.). Each subject was exposed to both placebo and one active dose over 2- to 5-consecutive-day intervals, and dose conditions (i.e., placebo or active) alternated throughout the study. Active marijuana smoking significantly decreased the number of daily tobacco smoking bouts, increased inter-bout intervals and decreased inter-puff intervals. Marijuana decreased the number of tobacco smoking bouts by delaying the initiation of tobacco cigarette smoking immediately after marijuana smoking, whereas decreases in inter-puff intervals were unrelated to the time of marijuana smoking. No consistent interactions between marijuana effects and social or private periods (i.e., time of day) were observed.

Deficits in motor control are often reported in children with prenatal alcohol exposure (PAE). Less is known about the effects of prenatal tobacco exposure (PTE) and prenatal marijuana exposure (PME) on motor coordination, and previous studies have not considered whether PTE, PAE, and PME interact to affect motor control. This study investigated the effects of PTE, PAE, and PME as well as current drug use on speed of processing, visual-motor coordination, and interhemispheric transfer in 16-year-old adolescents. Data were collected as part of the Maternal Health Practices and Child Development Project. Adolescents (age 16, n=320) participating in a longitudinal study of the effects of prenatal substance exposure on developmental outcomes were evaluated in this study. The computerized Bimanual Coordination Test (BCT) was used to assess each domain of function. Other important variables, such as demographics, home environment, and psychological characteristics of the mother and adolescent were also considered in the analyses. There were significant and independent effects of PTE, PAE, and PME on processing speed and interhemispheric transfer of information. PTEand PME were associated with deficits in visual motor coordination. There were no interactions between PAE, PTE, and PME. Current tobacco use predicted deficits in speed of processing. Current alcohol and marijuana use by the offspring were not associated with any measures of performance on the BCT. PMID:20600845

Objectives This study examines factors associated with availability of tobacco products for marijuana cigars (i.e., blunts) in 50 non-contiguous mid-sized California communities. Methods The study is based on data collected in 943 tobacco outlets. Neighborhood demographics, community adult marijuana prevalence, medical marijuana policy and access to medical marijuana dispensaries and delivery services were included. Results Multilevel logistic regression analyses indicated that compared with small markets, availability of tobacco products associated with use of blunts was significantly higher in convenience stores, smoke/tobacco shops and liquor stores. None of the neighborhood demographics were associated with availability of blunt wrappers and only a small percent of Whites was positively associated with availability of blunt cigars, small cigars or cigarillos at the store. Controlling for outlet type and neighborhood demographics, higher city prevalence of adult marijuana use was associated with greater availability of blunt wrappers. Also, policy that permits medical marijuana dispensaries or private cultivation was positively associated with availability of tobacco products for blunts. Density of medical marijuana dispensaries and delivery services, however, was negatively associated with greater availability of these products at tobacco outlets. Conclusions Results suggest that availability of tobacco products associated with blunts is similar in neighborhoods with different socioeconomic status and racial and ethnic composition. Results also suggest the important role that community norms that support marijuana use or legalization of medical marijuana and medical marijuana policy may play in increasing availability of tobacco products associated with blunts.

Goncy, Elizabeth A; Mrug, Sylvie

2013-03-01

This study examined the location and time of adolescent use of cigarettes, alcohol, and marijuana. Age, gender, and racial differences in location and time of use were studied for each substance. Using cross-sectional data collected through the schoolwide Pride Survey, 20,055 students between the ages of 10 and 19 years (53.6% female, 55.1% Black, 44.9% White) in one metropolitan area reported on their frequency of cigarette, alcohol, and marijuana use, as well as the location and time of use of each substance. Chi-square tests compared the rates, locations, and times for each substance across boys and girls; Black and White students; and early, middle, and late adolescents. Older adolescents reported higher rates of substance use at friends' homes, at school, and in cars and lower rates of alcohol use at home compared with younger youth. Males were more likely to report alcohol and marijuana use at school and on weeknights and alcohol use in cars, whereas females were more likely to report alcohol and marijuana use on the weekends. No gender differences emerged for times and locations of cigarette use. Compared with Black youth, White adolescents were more likely to use all substances at friends' homes and on weekends; to smoke cigarettes at school, in the car, and on weeknights; and to use alcohol at home. Black adolescents were more likely to report using alcohol at home, at school, in cars, during and after school, and on weeknights and were more likely to report using marijuana at school. The location and time of adolescent substance use vary substantially by age, gender, and race. These differences may help tailor substance use prevention and intervention programs to specific subgroups of youth to improve program effectiveness.

Explicit and implicit effects of anti-marijuana and anti-tobacco TV advertisements.

Czyzewska, Maria; Ginsburg, Harvey J

2007-01-01

Effects of anti-tobacco and anti-marijuana TV advertisements on explicit (i.e., semantic differential ratings) and implicit (i.e. Implicit Association Test, IAT) attitudes toward tobacco and marijuana were compared. Two hundred twenty nine, 18- to 19-year-old U.S. college students were randomly assigned to anti-tobacco or anti-marijuana PSA viewing conditions. Participants completed a short survey on attitudes to tobacco and marijuana. Afterwards they watched 15 PSAs embedded in a 15-min science program. At the end, all participants completed IAT for marijuana, IAT for tobacco and the assessment of explicit attitudes. Results of ANCOVA revealed a significant interaction between type of TV PSAs watched and implicit attitudes, F(1,223)=7.12, p<0.01 when controlling for preexisting attitudes to both substances; the implicit attitudes were more negative toward the substance that corresponded to the content of advertisements watched (i.e., anti-tobacco or anti-marijuana). However, analogical analysis on explicit measures showed that attitudes to marijuana became less negative among students that watched anti-marijuana ads than the group with anti-tobacco ads, F(1,222)=5.79, p<0.02. The discussion focused on the practical and theoretical implications of the observed dissociation between implicit and explicit attitudes to marijuana after the exposure to anti-marijuana PSAs.

Aim User practices/rituals that involve concurrent use of tobacco and marijuana – smoking blunts and “chasing” marijuana with tobacco – are hypothesized to increase cannabis dependence symptoms. Design Ethnographers administered group surveys to a diverse, purposive sample of marijuana users who appeared to be 17–35 years old. Setting New York City, including non-impoverished areas of Manhattan, the transitional area of East Village/Lower East Side, low-income areas of northern Manhattan and South Bronx, and diverse areas of Brooklyn and Queens. Participants 481 marijuana users ages 14–35, 57% male, 43% female; 27% White, 30% Black, 19% Latino, 5% Asian, 20% of other/multiple race. Measurements Among many other topics, group surveys measured cannabis dependence symptoms; frequencies of chasing, blunt smoking, joint/pipe smoking, using marijuana while alone, and general tobacco use; and demographic factors. Findings Blunt smoking and chasing marijuana with tobacco were each uniquely associated with five of the seven cannabis dependence symptoms. Across symptoms, predicted odds were 2.4–4.1 times greater for participants who smoked blunts on all 30 of the past 30 days than for participants who did not smoke blunts in the past 30 days. Significant increases in odds over the whole range of the five-point chasing frequency measure (from never to always) ranged from 3.4 times to 5.1 times. Conclusions Using tobacco with marijuana – smoking blunts and “chasing” marijuana with tobacco – contributes to cannabis dependence symptoms. Treatment for cannabis dependence may be more effective it addresses the issue of concurrent tobacco use. PMID:18339491

With an increase in marijuana use among adults in the United States (US), understanding the potential impact of marijuana use on tobacco use and associated behavioral and health consequences, including respiratory conditions, is necessary. Survey responses from Wave 1 of the nationally representative Population Assessment of Tobacco and Health (PATH) Study were used to assess tobacco use and marijuana use among non-current tobacco users (n = 17,952) and current established tobacco-users classified as: cigarette only users (n = 8689), e-cigarette only users (n = 437), cigar only (traditional, cigarillo, or filtered) users (n = 706), hookah only users (n = 461), smokeless tobacco only users (n = 971), cigarette + e-cigarette users (n = 709), and users of multiple tobacco products (n = 2314). When compared to non-current tobacco users, each tobacco user group except smokeless only users had higher odds (odds ratios ranging from 3.86-8.07) of reporting current marijuana use. Among current tobacco users, higher levels of tobacco dependence did not explain the relationship between tobacco use and marijuana use. Additionally, concurrent marijuana use was associated with lower odds of attempts to quit tobacco (OR = 0.86, 95% CI = 0.79, 0.94, p < 0.001) and a higher probability (OR = 1.35, 95CI = 1.21, 1.51, p < 0.01) of reporting a history of respiratory disease. The association between concurrent use of tobacco and marijuana and higher tobacco dependence and lower rates of quit attempts suggests the potential for sustained tobacco use and deleterious health effects. Further, marijuana use may represent an additive risk for respiratory harm among concurrent users of tobacco and marijuana. Copyright © 2018 Elsevier B.V. All rights reserved.

Objectives To examine associations between current multiple tobacco product use, and current use of alcohol and marijuana, binge drinking, and lifetime use of marijuana, alcohol, and other drugs among US high school students. Methods Using 2013 Youth Risk Behavior Survey data (N = 13,583 high school students), logistic regression analyses were conducted to determine if single tobacco product or multiple tobacco product users are more likely to engage in other risk behaviors than zero tobacco product users, controlling for demographic variables. Results Overall, 23% of the sample used tobacco products and 10% of students reported current use of at least 2 tobacco products. Among single tobacco product users, the odds for engaging in risk behaviors ranged from 3.3 to 9.9 compared to non-tobacco users (p < .0001). Among multiple tobacco product users, the odds ranged from 1.5 to 4.7 (p < .01) compared to single tobacco product users. Conclusions Results suggest dual users are significantly more likely to engage in risk behavior than non-users and single product users. Future interventions should consider identifying dual-users as at higher risk, and targeting multiple risk behaviors. PMID:26685820

The transition from high school to college is a high-risk stage for the initiation and escalation of substance use. Substance use and its associated risk factors have been thoroughly described in developed countries, such as the United States, but largely neglected in Argentina, a South American country with patterns of a collectivist culture. The present cross-sectional study describes the occurrence of alcohol, tobacco, and marijuana use and the association between these behaviors and the age of onset of substance use and cognitive (i.e., risk perception) and social (i.e., prescriptive) variables in a large sample of Argentinean college freshmen (n = 4083, 40.1% men; mean age = 19.39 ± 2.18 years). The response rate across courses was ≥90% and was similarly distributed across sex. Participants completed a survey that measured substance use (alcohol [with a focus on heavy drinking and binge drinking behaviors], tobacco, and marijuana), age of onset of the use of each substance, perceived risk associated with various substance use behaviors, prescriptive norms associated with substance use, and descriptive norms for alcohol use (AU). The results indicated that AU is nearly normative (90.4 and 80.3% with last year and last month use, respectively) in this population, and heavy drinking is highly prevalent (68.6 and 54.9% with heavy episodic and binge drinking, respectively), especially among those with an early drinking onset (97.8 and 93.6% with last year and last month use and 87.8 and 76.3% with heavy episodic and binge drinking, respectively). The last-year occurrence of tobacco and marijuana use was 36 and 28%, respectively. Early substance use was associated with the greater use of that specific substance. The students overestimated their same-sex friend’s AU, and women overestimated the level of AU of their best male friend. At the multivariate level, all of the predictors, with the exception of the parents’ prescriptive norms, significantly explained

Objective To explore the intersection of tobacco, legalised marijuana and electronic vaporiser use among young adults in the ‘natural laboratory’ of Colorado, the first state with legalised retail marijuana. Methods We conducted semistructured interviews with 32 young adults (18–26 years old) in Denver, Colorado, in 2015 to understand the beliefs and practices related to the use of tobacco, marijuana and vaporisers. Results We found ambiguity about whether the phrase ‘to smoke’ refers to the use of tobacco or marijuana products. Smoking marijuana blunts (emptied cigarillo or tobacco wrap filled with marijuana) was common, but few interpreted this as tobacco use. Marijuana vaporisers were used to circumvent public consumption laws (eg, while at work or when driving). Young adults considered secondhand tobacco smoke dangerous, but perceived secondhand marijuana smoke as benign. Discussion Using tobacco products as a delivery method for marijuana (eg, blunts) might be increasing and normalising tobacco use among young adults. Surveillance should explicitly ask about use of tobacco products for marijuana. Marijuana vaporisers, often indistinguishable from nicotine vaporisers, may be used to circumvent public consumption laws; communities concerned about use of marijuana in public spaces should include vaporisers (for nicotine or marijuana) in smoke-free regulations. Tobacco, marijuana and electronic vaporisers should be studied together, rather than separately. This approach is essential in informing research and policy as more US states and countries worldwide move to legalise marijuana. PMID:27697954

Since at least the 1970s, tobacco companies have been interested in marijuana and marijuana legalization as both a potential and a rival product. As public opinion shifted and governments began relaxing laws pertaining to marijuana criminalization, the tobacco companies modified their corporate planning strategies to prepare for future consumer demand. Policymakers and public health advocates must be aware that the tobacco industry or comparable multinational organizations (eg, food and beverage industries) are prepared to enter the marijuana market with the intention of increasing its already widespread use. In order to prevent domination of the market by companies seeking to maximize market size and profits, policymakers should learn from their successes and failures in regulating tobacco. © 2014 Milbank Memorial Fund.

Approximately 70% of current (past 30-day) adult marijuana users are current tobacco users, which may complicate tobacco cessation. We assessed prevalence and trends in tobacco cessation among adult ever tobacco users, by marijuana use status. Data came from the National Survey on Drug Use and Health, a cross-sectional, nationally representative, household survey of U.S. civilians. Analyses included current, former, and never marijuana users aged≥18 reporting ever tobacco use (cigarette, cigar, chew/snuff). We computed weighted estimates (2013-2014) of current tobacco use, recent tobacco cessation (quit 30days to 12months), and sustained tobacco cessation (quit>12months) and adjusted trends in tobacco use and cessation (2005-2014) by marijuana use status. We also assessed the association between marijuana and tobacco use status. In 2013-2014, among current adult marijuana users reporting ever tobacco use, 69.1% were current tobacco users (vs. 38.5% of former marijuana users, p<0.0001, and 28.2% of never marijuana users, p<0.0001); 9.1% reported recent tobacco cessation (vs. 8.4% of former marijuana users, p<0.01, and 6.3% of never marijuana users, p<0.001), and 21.8% reported sustained tobacco cessation (vs. 53.1% of former marijuana users, p<0.01, and 65.5% of never marijuana users, p<0.0001). Between 2005 and 2014, current tobacco use declined and sustained tobacco cessation increased among all marijuana use groups. Current marijuana users who ever used tobacco had double the prevalence (vs. never-marijuana users) of current tobacco use, and significantly lower sustained abstinence. Interventions addressing tobacco cessation in the context of use of marijuana and other substances may be warranted. Copyright © 2017 Elsevier Ltd. All rights reserved.

Differences in reporting of perceived acute effects of alcohol use, marijuana use, and simultaneous alcohol and marijuana use.

2017-11-01

Although there are serious negative harms associated with simultaneous alcohol and marijuana (SAM) use, little is known about the self-reported acute effects of SAM use and how they may be similar to or different than effects experienced when using alcohol or marijuana only. The current study examines the perceived acute effects of SAM use, compared to using alcohol or marijuana only, as well as demographic and substance use predictors of overall SAM effects. Participants were a community sample of young adults ages 18-23 participating in a longitudinal study on social role transitions and substance use during young adulthood. Young adults who reported SAM use at least once in their lifetime were selected for the present analyses (N=315; mean age=21.42; 58% female) and reported the effects they experienced from typical alcohol use, marijuana use, and SAM use. There were significant differences in the extent to which young adults perceived the effects depending on the substances used. Most effects (i.e., clumsy, confused, dizzy, difficulty concentrating) were rated strongest when engaging in SAM use, compared to typical alcohol or marijuana use alone. Feeling high and feeling marijuana effects were rated strongest when engaging in marijuana use alone compared to SAM use, but feeling drunk was greater during SAM use compared to alcohol use alone. Greater alcohol use and increased time spent high during typical SAM use were associated with greater overall SAM effects. When young adults engage in SAM use they report experiencing greater negative physiological and cognitive effects. Copyright © 2017 Elsevier B.V. All rights reserved.

Marijuana and tobacco cigarettes: Estimating their behavioral economic relationship using purchasing tasks.

Although marijuana and tobacco are commonly coused, the nature of their relationship has not been fully elucidated. Behavioral economics has characterized the relationship between concurrently available commodities but has not been applied to marijuana and tobacco couse. U.S. adults ≥18 years who coused marijuana and tobacco cigarettes were recruited via Mechanical Turk, a crowdsourcing service by Amazon. Participants (N = 82) completed online purchasing tasks assessing hypothetical marijuana or tobacco cigarette puff consumption across a range of per-puff prices; 2 single-commodity tasks assessed these when only 1 commodity was available, and 2 cross-commodity tasks assessed these in the presence of a concurrently available fixed-price commodity. Purchasing tasks generated measures of demand elasticity, that is, sensitivity of consumption to prices. In single-commodity tasks, consumption of tobacco cigarette puffs (elasticity of demand: α = 0.0075; 95% confidence interval [0.0066, 0.0085], R² = 0.72) and of marijuana puffs (α = .0044; 95% confidence interval [0.0038, 0.0049], R² = 0.71) declined significantly with increases in price per puff. In cross-commodity tasks when both tobacco cigarette puffs and marijuana puffs were available, demand for 1 commodity was independent of price increases in the other commodity (ps > .05). Results revealed that, in this small sample, marijuana and tobacco cigarettes did not substitute for each other and did not complement each other; instead, they were independent of each other. These preliminary results can inform future studies assessing the economic relationship between tobacco and marijuana in the quickly changing policy climate in the United States.

This study examines the associations between e-cigarette use and tobacco, marijuana, and alcohol use among a large sample of Canadian youth. Using Canadian data from 39,837 grade 9 to 12 students who participated in year 3 (2014-2015) of the COMPASS study, logistic regression models were used to examine how current use of e-cigarettes were associated with tobacco, marijuana, binge drinking, and energy drinks mixed with alcohol. Pearson's chi-square tests were used to examine subgroup differences by sex. Overall, 9.75% of respondents were current e-cigarette users. Current cigarette smokers (odds ratio [OR] = 3.009), current marijuana users (OR = 5.549), and noncurrent marijuana users (OR = 3.653) were more likely to report using e-cigarettes than noncigarette smokers and nonmarijuana users. Gender differences among males and females showed higher risk of e-cigarette use among female current marijuana users (OR = 7.029) relative to males (OR = 4.931) and female current smokers (OR = 3.284) compared to males (OR = 2.862). Compared to nonbinge drinkers, weekly (OR = 3.253), monthly (OR = 3.113), and occasional (OR = 2.333) binge drinkers were more likely to use e-cigarettes. Similarly, students who consume energy drinks mixed with alcohol (OR = 1.650) were more likely to use e-cigarettes compared to students who do not consume them. We identify that youth who binge drink or use marijuana have a greater increased risk for using e-cigarettes compared to cigarette smokers. These data suggest that efforts to prevent e-cigarette use should not only be discussed in the domain of tobacco control. Copyright © 2016 Society for Adolescent Health and Medicine.

Most young adult women who smoke marijuana also drink alcohol. Marijuana-related problems are associated with marijuana use frequency. We hypothesized that increased alcohol use frequency potentiates the association between frequency of marijuana use and marijuana-related problem severity. We recruited women aged 18 to 24 who smoked marijuana at least monthly and were not treatment seeking. Marijuana and alcohol use were measured using the timeline follow-back method. Problems associated with marijuana use were assessed using the Marijuana Problems Scale. Participants (n = 332) averaged 20.5 ± 1.8 years of age, were 66.7% non-Hispanic White, and reported using marijuana on 51.5 ± 30.6 and alcohol on 18.9 ± 16.8 of the 90 previous days. Controlling for education, ethnicity, years of marijuana use, and other drug use, frequency of marijuana use (b = .22; p < .01) and frequency of alcohol use (b = 0.13; p < .05) had significant, positive effects on marijuana problem severity. In a separate multivariate model, the linear by linear interaction of marijuana by alcohol use frequency was significant (b = 0.18; p < .01), consistent with the hypothesis. Concurrent alcohol use impacts the experience of negative consequences from marijuana use in a community sample of young women. Discussions of marijuana use in young adults should consider the possible potentiating effects of alcohol use. Copyright © 2014 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Recent loosening of state and federal policy restrictions on marijuana, along with changes in social norms regarding marijuana use and decreases in prevalence of other types of substance use, may lead to increases in youth initiating marijuana before other types of substances such as alcohol and tobacco. We investigated predictors and potential consequences of initiating marijuana before other drugs for youth aged 12-21-years in the USA. Nationally representative, cross-sectional survey data from the US National Survey on Drug Use and Health supplied self-reported age of first marijuana, cigarettes, alcohol, other tobacco, and other illegal drug use among 12-21-year-old samples from 2004 to 2014 (n = 275,559). We first examined the degree to which initiating marijuana use first was associated with sex, age, race/ethnicity, and survey year. Then, we examined whether using marijuana first predicted heavy marijuana use, cannabis use disorder (CUD), alcohol use disorder (AUD), nicotine dependence (ND), or lifetime use of other illegal drugs. Among all survey youth (substance users and non-users), the proportion using marijuana first increased from 4.8 to 8.8% from 2004 to 2014. Those using marijuana first (vs. alcohol or cigarettes first) were more likely to be male and older and Black, American Indian/Alaskan Native, multiracial, or Hispanic than White or Asian. Among substance users and adjusting for age of onset and the number of substances used, using marijuana first was associated higher odds of heavy current marijuana use and CUD. In recent years, youth have been increasingly likely to use marijuana as their first drug and sequence of initiation is associated with race/ethnicity, gender, and age. Using marijuana first might increase the chance of heavy use and CUD.

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

Marijuana and tobacco are the most commonly used illicit and licit drugs during pregnancy. This study aimed to examine a nationally representative sample of US pregnant women and to: (1) determine the prevalence of past month marijuana and tobacco co-use, (2) identify characteristics that distinguish marijuana and tobacco co-users from users of marijuana only, tobacco only, or neither, and (3) compare characteristics that differ between pregnant and non-pregnant co-users of marijuana and tobacco. Data were obtained from 497,218 US women (8721 pregnant) ages 12-49 who participated in the 2005-2014 National Survey on Drug Use and Health. Prevalence and demographic and substance use characteristics were compared across groups using weighted estimates and chi-squared tests. Multinomial logistic regression identified demographic and substance use correlates of co-use. Co-use among pregnant and non-pregnant women was significantly more prevalent than marijuana-only use but was less common than tobacco-only use. In unadjusted frequencies, pregnant co-users significantly differed from non-pregnant co-users across several domains. Among pregnant women, multivariate correlates of co-use of tobacco and marijuana vs. tobacco-only use were ages 12-17, non-Hispanic black race, Hispanic ethnicity, and past month polytobacco, any alcohol, and other drug use (all adjusted odds ratios≥2.0). In this first examination of the prevalence and correlates of co-use of marijuana and tobacco among a nationally representative group of pregnant women, pregnant co-users were more likely to report other high risk behaviors compared with non-pregnant co-users and users of a single substance, suggesting disparities worthy of further investigation.

The aim of the current investigation was to examine uni-morbid and co-occurring tobacco and marijuana use in relation to the negative emotional symptoms of anxiety and depression. Participants were 250 adult individuals (132 female; mage = 22.43, SD = 9.00), falling into one of four non-overlapping substance use categories: tobacco use only (n = 39), marijuana use only (n = 62), co-occurring tobacco and marijuana use (n = 82), and neither tobacco nor marijuana use (n = 67). Results revealed three key findings. First, tobacco-only using individuals reported significantly greater negative affectivity than any of the other groups. Second, tobacco-only users reported greater anxious arousal symptoms than either the marijuana or non-substance-using groups, but not the combined group. Third, tobacco-only users reported greater levels of depressive symptoms than either marijuana users or non-substance-users. These findings provide novel information about tobacco and marijuana use, and how these variables relate to the experience of general and specific types of negative emotional symptoms. PMID:20390700

Marijuana contains carcinogens similar to tobacco smoke and has been suggested by relatively small studies to increase the risk of head and neck cancer (HNC). Because tobacco is a major risk factor for HNC, large studies with substantial numbers of never tobacco users could help to clarify whether marijuana smoking is independently associated with HNC risk. We pooled self-reported interview data on marijuana smoking and known HNC risk factors on 4,029 HNC cases and 5,015 controls from five case-control studies within the INHANCE Consortium. Subanalyses were conducted among never tobacco users (493 cases and 1,813 controls) and among individuals who did not consume alcohol or smoke tobacco (237 cases and 887 controls). The risk of HNC was not elevated by ever marijuana smoking [odds ratio (OR), 0.88; 95% confidence intervals (95% CI), 0.67-1.16], and there was no increasing risk associated with increasing frequency, duration, or cumulative consumption of marijuana smoking. An increased risk of HNC associated with marijuana use was not detected among never tobacco users (OR, 0.93; 95% CI, 0.63-1.37; three studies) nor among individuals who did not drink alcohol and smoke tobacco (OR, 1.06; 95% CI, 0.47-2.38; two studies). Our results are consistent with the notion that infrequent marijuana smoking does not confer a risk of these malignancies. Nonetheless, because the prevalence of frequent marijuana smoking was low in most of the contributing studies, we could not rule out a moderately increased risk, particularly among subgroups without exposure to tobacco and alcohol.

Alcohol and marijuana use among college students: economic complements or substitutes?

2004-09-01

Previous research has shown that the recent tightening of college alcohol policies has been effective at reducing college students' drinking. Over the period in which these stricter alcohol policies have been put in place, marijuana use among college students has increased. This raises the question of whether current policies aimed at reducing alcohol consumption are inadvertently encouraging marijuana use. This paper begins to address this question by investigating the relationship between the demands for alcohol and marijuana for college students using data from the 1993, 1997 and 1999 waves of the Harvard School of Public Health's College Alcohol Study (CAS). We find that alcohol and marijuana are economic complements and that policies that increase the full price of alcohol decrease participation in marijuana use.

Background Marijuana policies are rapidly evolving. In the United States, recreational use of marijuana is now legal in four states and medical marijuana is legal in 23 states. Research evaluating such policies has focused primarily on how policies affect issues of price, access to, use, and consequences of marijuana. Due to potential spillover effects, researchers also need to examine how marijuana policies may impact use and consequences of alcohol. Methods The current paper is a critical review of articles evaluating alcohol outcomes associated with marijuana decriminalization, medical marijuana legalization, and non-medical or recreational marijuana legalization. We identified articles and reports through (1) online searches of EBSCO host database including Academic search premier, Econlit, Legal collection, Medline, Psych articles, and PsycINFO, as well as PubMed and Google Scholar databases; (2) review of additional articles cited in papers identified through electronic searches; and (3) targeted searches of state and local government records regarding marijuana law implementation. We reviewed studies with respect to their data sources and sample characteristics, methodology, and the margin of alcohol and marijuana use, timing of policy change, and the aspects of laws examined. Results The extant literature provides some evidence for both substitution (i.e., more liberal marijuana policies related to less alcohol use as marijuana becomes a substitute) and complementary (i.e., more liberal marijuana policies related to increases in both marijuana and alcohol use) relationships in the context of liberalization of marijuana policies in the United States. Conclusions Impact of more liberal marijuana policies on alcohol use is complex, and likely depends on specific aspects of policy implementation, including how long the policy has been in place. Further, evaluation of marijuana policy effects on alcohol use may be sensitive to the age group studied and the

Factors associated with regular marijuana use among high school students: a long-term follow-up study.

The present study investigated whether several behavioral and psychosocial factors measured during early adolescence predicted regular marijuana use 6 years later in a sample of high school students. As part of a school-based survey. 7th-grade students (N = 1,132) reported levels of alcohol, tobacco, and marijuana use, and were assessed on several domains of psychosocial functioning potentially relevant in the etiology of marijuana use. When students were followed-up in the 12th-grade, 14% smoked marijuana on a regular basis (once or more per month). Findings indicated that early cigarette smoking, alcohol use, and alcohol intoxication predicted later regular marijuana use. For boys, early marijuana use increased the odds for later regular marijuana use. Cigarette smoking by friends and siblings during early adolescence also increased the likelihood of later monthly marijuana use. The findings suggest that early prevention programs for adolescent alcohol, tobacco, and/or other drug use may have important preventive effects in terms of potentially more serious levels of marijuana involvement later in adolescence and early adulthood.

Prevalence and Perceived Financial Costs of Marijuana versus Tobacco use among Urban Low-Income Pregnant Women.

To examine the relative prevalence of marijuana and tobacco use among low-income post-partum women, using self-report, urine, and hair testing data; and to further explore perceptions of the substances among postpartum women by evaluating perceived risk and monetary cost of prenatal marijuana versus tobacco use. Data from two studies were available for a total of 100 (Study 1) and 50 (Study 2) low-income, primarily African-American post-partum women. Study 1 participants completed brief self-report measures of substance use as well as urine and hair samples; study 2 participants completed a brief opinion survey regarding the risks and monetary costs of prenatal marijuana use. In Study 1, the self-reported prevalence of any tobacco or marijuana use in the past three months was 17% and 11%, respectively. However, objectively-defined marijuana use was more prevalent than self-reported tobacco use: 14% tested positive for marijuana by urinalysis, and 28% by hair analysis. Study 2 participants were more likely to believe that there is a safe level of marijuana use during pregnancy, and nearly half believed that using marijuana during pregnancy was less expensive than smoking cigarettes. Marijuana use may be as or more prevalent than tobacco use among low-income, African-American pregnant women. These findings may in part be attributable to perceptions of roughly equivalent cost and the lack of a clear public health message regarding prenatal marijuana use, combined with growing pro-marijuana advocacy. A broader public health response to address prenatal marijuana use, along with other substances of abuse, is needed.

Few marijuana smokers in treatment achieve sustained abstinence, yet factors contributing to high relapse rates are unknown. Study 1: data from five inpatient laboratory studies assessing marijuana intoxication, withdrawal, and relapse were combined to assess factors predicting the likelihood and severity of relapse. Daily, nontreatment-seeking marijuana smokers (n = 51; 10 ± 5 marijuana cigarettes/day) were enrolled. Study 2: to isolate the effects of cigarette smoking, marijuana intoxication, withdrawal, and relapse were assessed in daily marijuana and cigarette smokers (n = 15) under two within-subject, counter-balanced conditions: while smoking tobacco cigarettes as usual (SAU), and after at least 5 days without cigarettes (Quit). Study 1: 49% of participants relapsed the first day active marijuana became available. Tobacco cigarette smokers (75%), who were not abstaining from cigarettes, were far more likely to relapse than non-cigarette smokers (odds ratio: 19, p < .01). Individuals experiencing more positive subjective effects (i.e., feeling "high") after marijuana administration and those with more negative affect and sleep disruption during marijuana withdrawal were more likely to have severe relapse episodes (p < .05). Study 2: most participants (>87%) relapsed to marijuana whether in the SAU or Quit phase. Tobacco cigarette smoking did not significantly influence relapse, nor did it affect marijuana intoxication or most symptoms of withdrawal relative to tobacco cessation. Daily marijuana smokers who also smoke cigarettes have high rates of marijuana relapse, and cigarette smoking versus recent abstinence does not directly influence this association. These data indicate that current cigarette smoking is a clinically important marker for increased risk of marijuana relapse. Copyright © 2013 Society of Biological Psychiatry.

Cortical thickness abnormalities have been identified in youth using both alcohol and marijuana. However, limited studies have followed individuals pre- and post initiation of alcohol and marijuana use to help identify to what extent discrepancies in structural brain integrity are pre-existing or substance-related. Adolescents (N=69) were followed from ages 13 (pre-initiation of substance use, baseline) to ages 19 (post-initiation, follow-up). Three subgroups were identified, participants that initiated alcohol use (ALC, n=23, >20 alcohol use episodes), those that initiated both alcohol and marijuana use (ALC+MJ, n=23, >50 marijuana use episodes) and individuals that did not initiate either substance regularly by follow-up (CON, n=23, <3 alcohol use episodes, no marijuana use episodes). All adolescents underwent neurocognitive testing, neuroimaging, and substance use and mental health interviews. Significant group by time interactions and main effects on cortical thickness estimates were identified for 18 cortical regions spanning the left and right hemisphere (ps<0.05). The vast majority of findings suggest a more substantial decrease, or within-subjects effect, in cortical thickness by follow-up for individuals who have not initiated regular substance use or alcohol use only by age 19; modest between-group differences were identified at baseline in several cortical regions (ALC and CON>ALC+MJ). Minimal neurocognitive differences were observed in this sample. Findings suggest pre-existing neural differences prior to marijuana use may contribute to initiation of use and observed neural outcomes. Marijuana use may also interfere with thinning trajectories that contribute to morphological differences in young adulthood that are often observed in cross-sectional studies of heavy marijuana users.

Tobacco shops, medical marijuana dispensaries (MMD), and off-sale alcohol outlets are legal and prevalent in South Los Angeles, California-a high-crime, low-income urban community of color. This research is the first to explore the geographic associations between these three legal drug outlets with surrounding crime and violence in a large low-income urban community of color. First, spatial buffer analyses were performed using point-location and publically accessible January-December 2014 crime data to examine the geography of all felony property and violent crimes occurring within 100, 200, 500, and 1000-foot buffers of these three legal drug outlet types across South Los Angeles. Next, spatial regression analyses explored the geographic associations between density of these outlets and property and violent crimes at the census tract level. Results indicated that mean property and violent crime rates within 100-foot buffers of tobacco shops and alcohol outlets-but not MMDs-substantially exceeded community-wide mean crime rates and rates around grocery/convenience stores (i.e., comparison properties licensed to sell both alcohol and tobacco). Spatial regression analyses confirmed that tobacco shops significantly positively associated with property and violent crimes after controlling for key neighborhood factors (poverty, renters, resident mobility, ethnic/racial heterogeneity). Thus, study findings provide the first empirical evidence that tobacco shops may constitute public health threats that associate with crime and violence in U.S. low-income urban communities of color. Implementing and enforcing control policies that regulate and monitor tobacco shops in these communities may promote community health by improving public safety. Copyright © 2017 Elsevier Inc.

2008-02-01

The chemical composition of tobacco smoke has been extensively examined, and the presence of known and suspected carcinogens in such smoke has contributed to the link between tobacco smoking and adverse health effects. The consumption of marijuana through smoking remains a reality and, among youth, seems to be increasing. There have been only limited examinations of marijuana smoke, including for cannabinoid content and for tar generation. There have not been extensive studies of the chemistry of marijuana smoke, especially in direct comparison to tobacco smoke. In this study, a systematic comparison of the smoke composition of both mainstream and sidestream smoke from marijuana and tobacco cigarettes prepared in the same way and consumed under two sets of smoking conditions, was undertaken. This study examined the suite of chemicals routinely analyzed in tobacco smoke. As expected, the results showed qualitative similarities with some quantitative differences. In this study, ammonia was found in mainstream marijuana smoke at levels up to 20-fold greater than that found in tobacco. Hydrogen cyanide, NO, NO x , and some aromatic amines were found in marijuana smoke at concentrations 3-5 times those found in tobacco smoke. Mainstream marijuana smoke contained selected polycyclic aromatic hydrocarbons (PAHs) at concentrations lower than those found in mainstream tobacco smoke, while the reverse was the case for sidestream smoke, with PAHs present at higher concentrations in marijuana smoke. The confirmation of the presence, in both mainstream and sidestream smoke of marijuana cigarettes, of known carcinogens and other chemicals implicated in respiratory diseases is important information for public health and communication of the risk related to exposure to such materials.

Policy coherence, integration, and proportionality in tobacco control: Should tobacco sales be limited to government outlets?

PubMed

Smith, Elizabeth A; McDaniel, Patricia A; Hiilamo, Heikki; Malone, Ruth E

2017-08-01

Multiple factors, including marijuana decriminalization/legalization, tobacco endgame discourse, and alcohol industry pressures, suggest that the retail regulatory environment for psychoactive or addictive substances is a dynamic one in which new options may be considered. In most countries, the regulation of tobacco, marijuana, and alcohol is neither coherent, nor integrated, nor proportional to the potential harms caused by these substances. We review the possible consequences of restricting tobacco sales to outlets run by government-operated alcohol retail monopolies, as well as the likely obstacles to such a policy. Such a move would allow governments more options for regulating tobacco sales, and increase coherence, integration, and proportionality of substance regulation. It might also serve as an incremental step toward an endgame goal of eliminating sales of commercial combustible tobacco.

Although studies have identified an increased likelihood of marijuana and tobacco co-use among African Americans as compared to other racial groups, few studies have specifically examined the prevalence and substance use characteristics of co-users among African Americans in a national survey. The current secondary analysis examined the prevalence rates and substance use characteristics (e.g., marijuana dependence) of 2024 African American past month marijuana and tobacco users and co-users participating in the 2013 National Survey on Drug Use and Health. Findings revealed that 18.5%, 53.8% and 27.7% of African Americans smoked marijuana only, tobacco only and marijuana and tobacco in the past 30days, respectively. Relative to participants who smoked marijuana only, African Americans who smoked marijuana and tobacco were more likely to be marijuana dependent in the past year and report more days of marijuana use in the past month. Further, relative to participants who smoked tobacco only, African Americans who smoked marijuana and tobacco were less likely to be dependent on nicotine, reported fewer days of cigarette use in the past month, and began smoking cigarettes, cigars and marijuana at a younger age, but were more likely to be marijuana dependent in the past year and reported more days of cigar use in the past month. Marijuana and tobacco co-use is a significant public health problem, especially among African Americans. Additional research on effective prevention and treatment interventions for African Americans who smoke marijuana and tobacco is warranted. Copyright © 2015 Elsevier Ltd. All rights reserved.

In 2004, we surveyed 1,211 students at a large high school in suburban Pittsburgh regarding substance use, exposure to entertainment media, and covariates. Of the respondents, 52% were female, 8% were non-White, 27% reported smoking marijuana, and 60% reported using alcohol. They reported average exposure to 8.6 hr of media daily. In adjusted models, exposure to music was independently associated with marijuana use, but exposure to movies was independently associated with alcohol use. Implications, limitations, and suggestions for further research are discussed.

Tobacco use is the leading cause of preventable death worldwide. If current trends persist, tobacco will kill more than 8 million people worldwide by 2030 and 1 billion by the end of the century. The purpose of this study was to determine trends in tobacco/marijuana use in Nevada adolescents and their effect on dental health status. Relative comparative data were compared with nationally reported data. Retrospective data in this cohort study was from an ongoing statewide, school-based, dental health screening initiative that was conducted across 8 years (2002-2010) in public/private middle/high schools in Nevada. A total of 66,941 dental health screenings of adolescents between ages 13-18 were conducted. Self-reported data were collected on tobacco/marijuana use. Descriptive statistics and trends were reported. Means (SE) were computed for caries prevalence and severity. Effect size was reported on dental caries and use of tobacco/marijuana. Overall, percentage prevalence of tobacco use was approximately the same as the national average; however, there were significantly higher rates of marijuana use (12.0% vs. 3.3%). Prevalence and severity of dental caries was significantly higher in those who used tobacco/marijuana than those who did not across all variables and across all 8 years controlling for gender, race/ethnicity, where they lived, and exposure to secondhand smoke. Tobacco use negatively affected dental health status with marijuana having the largest negative effect. The findings from this study identified the need for tobacco/marijuana prevention services targeting adolescents residing in the geographic areas most at risk.

Introduction Ease of access to substances has been shown to have a direct and significant relationship with substance use for school-aged children. Previous research involving rural samples of middle and high school students reveals that perceived ease of access to substances is a significant predictor of recent use among rural adolescents; however, it is unclear if perceived access to substances varies between rural and urban areas. The purpose of the current study was to examine rural-urban differences in perceived ease of access to alcohol, smoking and chewing tobacco, marijuana, and seven other substances in order to better inform and promote future substance use prevention and programming efforts in rural areas. Methods Data were analyzed from the 2013 Georgia Student Health Survey II, administered in all public and interested private/charter schools in the state of Georgia. A total of 513,909 students (18.2% rural) indicated their perceived ease of access to 11 substances on a 4-point Likert-type scale. Rural-urban differences were investigated using chi-square analysis. Results In general, it appeared the rural-urban differences fell along legal/illicit lines. For middle school students, a significant difference in perceived ease of access was found for each substance, with rural students reporting greater access to smoking tobacco, chewing tobacco, and steroids, and urban students reporting greater access to alcohol, marijuana, cocaine, inhalants, ecstasy, methamphetamine, hallucinogens, and prescription drugs. Rural high school students reported higher access to alcohol, smoking tobacco, chewing tobacco, and steroids, with urban students reporting higher access to marijuana, cocaine, inhalants, ecstasy, and hallucinogens. Perceptions of ease of access more than doubled for each substance in both geographies between middle and high school. Conclusions In summary, the current study found multiple and fairly consistent differences between rural and urban

Objective: This investigation examined the concurrent validity of a new video simulation assessing adolescent alcohol and marijuana decision making in peer contexts (A-SIDE). Method: One hundred eleven youth (60% female; age 14–19 years; 80% White, 12.6% Latino; 24% recruited from treatment centers) completed the A-SIDE simulation, self-report measures of alcohol and marijuana use and disorder symptoms, and measures of alcohol (i.e., drinking motives and expectancies) and marijuana (i.e., expectancies) cognitions in the laboratory. Results: Study findings support concurrent associations between behavioral willingness to use alcohol and marijuana on the simulation and current use variables as well as on drinking motives and marijuana expectancies. Relations with use variables were found even when sample characteristics were controlled. Interestingly, willingness to accept nonalcoholic beverages (e.g., soda) and food offers in the simulation were inversely related to recent alcohol and marijuana use behavior. Conclusions: These findings are consistent with prior work using laboratory simulations with college students and provide preliminary validity evidence for this procedure. Future work is needed to examine the predictive utility of the A-SIDE with larger and more diverse samples of youth. PMID:25343652

We performed a secondary analysis of Adolescent Health Risk Behavior Survey data ( N = 937), examining associations between lifetime alcohol and marijuana use with intrapersonal (i.e., risk perceptions) and interpersonal (e.g., peer approval and behavior) factors. Multinomial and binary logistic regression analyses contend students reporting lifetime alcohol use-compared to students who had never used alcohol or marijuana-perceived lower alcohol risk ( p < .001), higher friend drinking approval ( p < .001), and greater friend drinking ( p = .003). Using both alcohol and marijuana in one's life was associated with being in public schools ( p = .010), higher grade levels ( p = .001), lower perceived alcohol ( p = .011) and marijuana use risk ( p = .003), higher friend approval of alcohol ( p < .001) and marijuana use ( p < .001), and believed more friends used alcohol ( p < .001). Compared to lifetime alcohol only, perceived friend academic performance decreased the risk of lifetime alcohol and marijuana use ( p = .043). Findings are beneficial to school nurses with students experiencing effects associated with substance use.

To explore the sentiment and themes of Twitter chatter that mentions both alcohol and marijuana. Cross-sectional analysis of tweets mentioning both alcohol and marijuana during 1 month was performed. The study setting was Twitter. Tweets sent from February 4 to March 5, 2014, were studied. A random sample (n = 5000) of tweets that mentioned alcohol and marijuana were qualitatively coded as normalizing both substances, preferring one substance over the other, or discouraging both substances. Other common themes were identified. More than half (54%) of the tweets normalized marijuana and alcohol (without preferring one substance over the other), and 24% preferred marijuana over alcohol. Only 2% expressed a preference for alcohol over marijuana, 7% discouraged the use of both substances, and the sentiment was unknown for 13% of the tweets. Common themes among tweets that normalized both substances included using the substances with friends (17%) and mentioning substance use in the context of sex or romance (14%). Common themes among tweets that preferred marijuana over alcohol were the beliefs that marijuana is safer than alcohol (46%) and preferences for effects of marijuana over alcohol (40%). Tweets normalizing polysubstance use or encouraging marijuana use over alcohol use are common. Both online and offline prevention efforts are needed to increase awareness of the risks associated with polysubstance use and marijuana use.

Tobacco and marijuana are commonly used by college students and have negative health effects. The purpose of the study was to understand how students' attitudes, intentions, and behaviors toward tobacco and marijuana change during freshman year and to examine how attitude and intention predict use of these substances. College students completed phone interviews before and after freshman year. The identical interviews assessed students' attitudes, intentions, and behaviors toward both substances. Attitude was measured on a 0-6 scale (6 = most positive), intention on a 0-5 scale (5 = very likely to use), and behavior by lifetime use (yes or no) and current use (past-28-days). Overall, 275 participants completed both interviews. Attitudes increased (tobacco 0.9 to 1.2, p < 0.01; marijuana 1.9 to 2.3, p < 0.01). Intentions increased (tobacco 0.4 to 0.8, p = 0.03; marijuana 0.7 to 1.1, p < 0.01). 12.2% initiated tobacco, 13.5% initiated marijuana. Only intention predicted tobacco initiation, while both attitude and intention predicted marijuana initiation. Attitudes, intentions, and behaviors changed significantly towards favored use. Predictors of use varied by substance, suggesting that different prevention approaches may be beneficial.

Twitter is among the most popular social media platforms used by young adults, yet it has been underutilized in substance use research compared with older platforms (e.g., MySpace and Facebook). We took a first step toward studying the associations between exposure to pro-alcohol- and marijuana-related content among young adults via Twitter and current heavy episodic drinking and current marijuana use, respectively. We conducted an online survey of 587 (254 men, 333 women) Twitter users between ages 18 and 25 years in February 2014 using an online survey system that has been previously used in research on health behaviors and attitudes. Current heavy episodic drinking was significantly associated with higher levels of exposure to pro-alcohol content. Similarly, current marijuana use was significantly associated with higher levels of exposure to pro-marijuana content. Our findings suggest that in-depth research regarding young adults' exposure to pro-alcohol- and marijuana-related content via Twitter may provide a foundation for developing effective prevention messages on this social media platform to counter the pro-alcohol and marijuana messages.

This study tests the impact of an in-school mediated communication campaign based on social marketing principles, in combination with a participatory, community-based media effort, on marijuana, alcohol and tobacco uptake among middle-school students. Eight media treatment and eight control communities throughout the US were randomly assigned to condition. Within both media treatment and media control communities, one school received a research-based prevention curriculum and one school did not, resulting in a crossed, split-plot design. Four waves of longitudinal data were collected over 2 years in each school and were analyzed using generalized linear mixed models to account for clustering effects. Youth in intervention communities (N = 4,216) showed fewer users at final post-test for marijuana [odds ratio (OR) = 0.50, P = 0.019], alcohol (OR = 0.40, P = 0.009) and cigarettes (OR = 0.49, P = 0.039), one-tailed. Growth trajectory results were significant for marijuana (P = 0.040), marginal for alcohol (P = 0.051) and non-significant for cigarettes (P = 0.114). Results suggest that an appropriately designed in-school and community-based media effort can reduce youth substance uptake. Effectiveness does not depend on the presence of an in-school prevention curriculum.

The present study sought to evaluate the day-to-day patterns of tobacco, alcohol and marijuana use among first year college students in the U.S. Using 210 days of weekly time-line follow-back diary data collected in 2002-2003, the authors examined within-person patterns of use. The sample was 48% female and 90% Caucasian. Sixty eight percent of the participants were permanent residents of Indiana. Univariate time series analysis was employed to evaluate behavioral trends for each substance across the academic year and to determine the predictive value of day-to-day substance use. Some of the most common trends included higher levels of substance use at the beginning and/or end of the academic year. Use on any given day could be predicted best from the amount of corresponding substance use one day prior. Conclusions While universal intervention might best be focused in the earliest weeks on campus and at the end of the year when substance use is at its highest, the diversity of substance use trajectories suggests the need for more targeted approaches to intervention. Study limitations are noted. PMID:18393083

Little is known about adolescents' interest in marijuana treatment programs. This question was evaluated by telephone interview in a convenience sample of 575 adolescents responding to advertisements for tobacco research studies. Eighty-one percent of respondents endorsed the need for marijuana treatment programs for adolescents. These adolescents were younger and less likely to smoke tobacco, smoke marijuana, or use alcohol than those not endorsing such a need. Among the 192 marijuana smokers, the 58.8% who endorsed the need for marijuana treatment programs took their first puff of marijuana at a younger age than those who did not endorse the need. Those who were willing to participate in a marijuana treatment program were more likely African American and took their first marijuana puff at a younger age than those not interested in treatment. These findings suggest that most adolescent marijuana smokers endorse the need for and are willing to attend marijuana treatment programs.

Among young adults, cigarette smoking is strongly associated with alcohol and marijuana use. The present study compared self-reported co-use of cigarettes and alcohol versus cigarettes and marijuana among young adults using cross-sectional survey data. Participants were young adult cigarette smokers (age 18 to 25) who also reported past month alcohol or marijuana use enrolled in a randomized trial testing a smoking cessation intervention on Facebook. Participants self-reported extent of cigarette smoking under the influence of alcohol or marijuana and differences in perceived pleasure from cigarette smoking when drinking alcohol compared to using marijuana. Among cigarette smokers who drank alcohol and used marijuana in the past month (n=200), a similar percentage of cigarettes were smoked under the influence of alcohol (42.4%±31.2%) and marijuana (43.1% ±30.0%). Among alcohol + marijuana users, perceived pleasure from smoking cigarettes was significantly greater when drinking alcohol versus when using marijuana (t (199) =7.05, p<0.001). There was, on average, an increase in perceived pleasure from smoking cigarettes when drinking alcohol, though perceived pleasure did not differ by binge drinking frequency. In contrast, there was on average no change in perceived pleasure from smoking cigarettes when using marijuana. Results from the cigarette smokers who used alcohol + marijuana were similar to cigarette smokers who only used alcohol (n=158) or only used marijuana (n=54). Findings highlight greater perceived reward from smoking cigarettes when drinking alcohol compared to when using marijuana, informing smoking cessation interventions that target users of multiple substances.

Recreational marijuana legalization (RML) went into effect in Oregon in July 2015. RML is expected to influence marijuana use by adolescents and young adults in particular, and by those with a propensity for substance use. We sought to quantify changes in rates of marijuana use among college students in Oregon from pre- to post-RML relative to college students in other states across the same time period. Repeated cross-sectional survey data from the 2012-16 administrations of the Healthy Minds Study. Seven 4-year universities in the United States. There were 10 924 undergraduate participants. One large public Oregon university participated in 2014 and 2016 (n = 588 and 1115, respectively); six universities in US states where recreational marijuana use was illegal participated both in 2016 and at least once between 2012 and 2015. Self-reported marijuana use in the past 30 days (yes/no) was regressed on time (pre/post 2015), exposure to RML (i.e. Oregon students in 2016) and covariates using mixed-effects logistic regression. Moderation of RML effects by recent heavy alcohol use was examined. Rates of marijuana use increased from pre- to post-2015 at six of the seven universities, a trend that was significant overall. Increases in rates of marijuana use were significantly greater in Oregon than in comparison institutions, but only among students reporting recent heavy alcohol use. Rates of Oregon college students' marijuana use increased (relative to that of students in other states) following recreational marijuana legislation in 2015, but only for those who reported recent heavy use of alcohol. Such alcohol misuse may be a proxy for vulnerabilities to substance use or lack of prohibitions (e.g. cultural) against it. © 2017 Society for the Study of Addiction.

As of 2015, more than half of U.S. states have legalized, medicalized, or decriminalized marijuana. This study examined the prevalence and correlates of support for marijuana legalization in a national sample of young adults and the intention to use marijuana more frequently if it were legalized. Data were from Wave 7 (weighted N = 3532) of the Truth Initiative Young Adult Cohort, a national sample of men and women aged 18-34. We assessed demographics, past 30-day substance (alcohol, tobacco, marijuana, other drug use), depression and anxiety, social smoking, marijuana harm perceptions (relative to cigarettes), and state-level marijuana policies as correlates of support for marijuana legalization and intentions to use marijuana more often if it were legalized. Multivariable models of correlates of support for legalization and intentions to use marijuana were conducted separately for the full sample and for nonmarijuana users. Weighted estimates showed that 39% of the full sample and 9% of nonmarijuana users supported marijuana legalization. Multivariable models showed that lower marijuana harm perceptions and lifetime and past 30-day tobacco use were common predictors of support for marijuana legalization and intentions to use marijuana among non-users of marijuana. Conclusions/Importance: Over a third of the sample supported marijuana legalization. Tobacco use and perceptions that marijuana is less harmful than cigarettes were robust risk correlates of support for marijuana legalization and intentions to use more frequently among nonusers. Public health campaigns should target these factors to deter marijuana-related harm in susceptible young adults.

Social inequalities have been associated with morbidity and mortality. Gender, ethnic group and inequalities were studied in an adolescent population to analyze alcohol, tobacco and cannabis consumption. We carried out a cross-sectional study of pupils from high schools in Burela (northern Spain) (n=238). We used the "Factors de Risc en Estudiants de Secundária" questionnaire designed by Agència de Salut Pública de Barcelona. nationality and weekly pocket money. Dependent variables: expectations and consumption of alcohol, tobacco and marihuana. Logistic regression was used. Participation in the study reached 91%. The proportion of pupils that have tried alcohol on occasion increases with age (27.3%, 47.7%, 75.9%), as with tobacco (1.8%, 7.6%, 17.0%), and cannabis (0%, 3.1%, 7.0%). Higher levels of spending money constitute a risk factor for tasting alcohol (OR=3.01), for high-risk consumption (OR=3.35), for getting drunk (OR=6.45) and for trying marijuana (OR=15.30). Sex and nationality were not shown to be associated with the use of any of these three drugs. The results of our study show that consumption of alcohol, tobacco and cannabis increases with age and with increased spending money. The data do not support the argument that foreign pupils are a risk group for alcohol consumption, so they should not be stigmatized.

In 2009, the Food and Drug Administration (FDA) banned characterising flavours in cigarettes (except for menthol) due to their appeal to teen starter smokers. In August 2016, the agency deemed all tobacco products to be under its authority and a more comprehensive flavour ban is under consideration. To determine the scope and scale of alcohol-flavoured tobacco products among cigars & cigarillos, hookahs and electronic cigarettes (e-cigarettes). Alcohol-flavoured tobacco products were identified by online search of tobacco purveyors' product lines and via Google search cross-referencing the various tobacco product types versus a list of alcoholic beverage flavours (eg, wine, beer, appletini, margarita). 48 types of alcohol-flavoured tobacco products marketed by 409 tobacco brands were identified. Alcohol flavours included mixed drinks (n=25), spirits (11), liqueurs (7) and wine/beer (5). Sweet and fruity tropical mixed drink flavours were marketed by the most brands: piña colada (96), mojito (66) and margarita (50). Wine flavours were common with 104 brands. Among the tobacco product categories, brands offering alcohol-flavoured e-cigarettes (280) were most numerous, but alcohol-flavoured products were also marketed by cigars & cigarillos (88) and hookah brands (41). Brands by major tobacco companies (eg, Philip Morris, Imperial Tobacco) were well represented among alcohol-flavoured cigars & cigarillos with five companies offering a total of 17 brands. The widespread availability of alcohol-flavoured tobacco products illustrates the need to regulate characterising flavours on all tobacco products. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The study aims were to examine daily associations between marijuana and alcohol use and the extent to which the association differs as a function of cannabis use disorder (CUD) and/or alcohol use disorder (AUD) diagnosis. Timeline Followback interview data was collected in a study of veterans (N = 127) recruited from a Veterans Affairs hospital who reported at least 1 day of co-use of marijuana and alcohol in the past 180 days (22,860 observations). Participants reported 40% marijuana use days, 28% drinking days, with 37% meeting DSM-5 criteria for CUD, 40% for AUD, and 15% for both. Use of marijuana on a given day was used to predict a 3-level gender-adjusted drinking variable (heavy: ≥5 (men)/4 (women) drinks; moderate: 1 to 4/3 drinks; or none: 0 drinks). A categorical 4-level variable (no diagnosis, AUD, CUD, or both) was tested as a moderator of the marijuana-alcohol relationship. Multilevel modeling analyses demonstrated that participants were more likely to drink heavily compared to moderately (OR = 2.34) and moderately compared to not drinking (OR = 1.61) on marijuana use days relative to nonuse days. On marijuana use days, those with AUD and those with AUD + CUD were more likely to drink heavily (OR = 1.91; OR = 2.51, respectively), but those with CUD were less likely to drink heavily (OR = 0.32) compared to moderately, nonsignificant differences between any versus moderate drinking in interaction models. Heavy drinking occurs on days when marijuana is also used. This association is particularly evident in individuals diagnosed with both AUD and CUD and AUDs alone but not in those with only CUDs. Findings suggest that alcohol interventions may need to specifically address marijuana use as a risk factor for heavy drinking and AUD. Copyright © 2018 by the Research Society on Alcoholism.

Worldwide, marijuana (cannabis) is a widely used drug. The incidence of marijuana smoking is increasing and is second only to tobacco as the most widely smoked substance in the general population. It is also the second most commonly used recreational drug after alcohol. Some adverse effects of marijuana smoking have been documented; however, the number of studies on the pulmonary effects of marijuana in individuals with leukemia is limited. In our case series, we report on 2 men with acute myeloid leukemia with miliary nodular lung patterns on computed tomography of the chest due to heavy marijuana use. We also report on 2 patients with acute lymphocytic leukemia who had a history of smoking marijuana and then developed lung opacities consistent with mold infection.

Motor vehicle accidents are the leading cause of death among youths and young adults aged 16-25 years in the United States (1). The prevalence of drinking and driving among high school students aged 16-19 years has declined by 54%, from 22.3% in 1991 to 10.3% in 2011 (2). However, the prevalence of weekend nighttime driving under the influence of marijuana (based on biochemical assays) among drivers aged ≥16 years has increased by 48%, from 8.6% in 2007 to 12.6% in 2013-2014 (3). Use of marijuana alone and in combination with alcohol has been shown to impair driving abilities (4-9). This report provides the most recent self-reported national estimates of driving under the influence of alcohol, marijuana, and alcohol and marijuana combined among persons aged 16-25 years, using data from the Substance Abuse and Mental Health Services Administration (SAMHSA) National Survey on Drug Use and Health (NSDUH) from 2002-2014. Prevalence data on driving under the influence of both substances were examined for two age groups (16-20 years and 21-25 years) and by sex and race/ethnicity. During 2002-2014, the prevalence of driving under the influence of alcohol alone significantly declined by 59% among persons aged 16-20 years (from 16.2% in 2002 to 6.6% in 2014; p<0.001) and 38% among persons 21-25 years (from 29.1% in 2002 to 18.1% in 2014; p<0.001). In addition, the prevalence of driving under the influence of alcohol and marijuana combined significantly declined by 39%, from 2.3% in 2002 to 1.4% in 2014 (p<0.001) among persons aged 16-20 years and from 3.1% in 2002 to 1.9% in 2014 (p<0.001) among persons aged 21-25 years. The prevalence of driving under the influence of marijuana alone declined 18%, from 3.8% in 2002 to 3.1% in 2014 (p = 0.05) only among persons aged 16-20 years.

Tobacco and marijuana are commonly used by college students and have negative health effects. The purpose of this study was to understand how students’ attitudes, intentions, and behaviors toward tobacco and marijuana change during freshman year and to examine how attitude and intention predict use of these substances. 275 college students completed phone interviews before and after their freshman year. The identical interviews assessed students’ attitudes, intentions, and behaviors toward both substances. Attitudes and intentions increased significantly. 12.2% of participants initiated tobacco use and 13.5% initiated marijuana use. Only intention predicted tobacco initiation, while both attitude and intention predicted marijuana initiation. Overall, attitudes, intentions, and behaviors changed significantly toward favored use. Predictors of use varied by substance, suggesting that different prevention approaches may be beneficial. PMID:24761133

The present study sought to inform models of risk for drugged driving through empirically identifying patterns of marijuana use, alcohol use, and related driving behaviors. Perceived dangerousness and consequences of drugged driving were evaluated as putative influences on risk patterns. We used latent profile analysis of survey responses from 897 college students to identify patterns of substance use and drugged driving. We tested the hypotheses that low perceived danger and low perceived likelihood of negative consequences of drugged driving would identify individuals with higher-risk patterns. Findings from the latent profile analysis indicated that a four-profile model provided the best model fit. Low-level engagers had low rates of substance use and drugged driving. Alcohol-centric engagers had higher rates of alcohol use but low rates of marijuana/simultaneous use and low rates of driving after substance use. Concurrent engagers had higher rates of marijuana and alcohol use, simultaneous use, and related driving behaviors, but marijuana-centric/simultaneous engagers had the highest rates of marijuana use, co-use, and related driving behaviors. Those with higher perceived danger of driving while high were more likely to be in the low-level, alcohol-centric, or concurrent engagers' profiles; individuals with higher perceived likelihood of consequences of driving while high were more likely to be in the low-level engagers group. Findings suggested that college students' perceived dangerousness of driving after using marijuana had greater influence on drugged driving behaviors than alcohol-related driving risk perceptions. These results support targeting marijuana-impaired driving risk perceptions in young adult intervention programs.

Objective This study identifies and compares outcomes in young adulthood associated with longitudinal patterns of alcohol and marijuana use during adolescence among urban youth. Method Data come from a cohort of 678 urban, predominantly Black children followed from ages 6–25 (1993–2012). Analyses are based on the 608 children who participated over time (53.6% male). Longitudinal patterning of alcohol and marijuana use were based on annual frequency reports from grades 8–12 and estimated through latent profile analysis. Results We identified four classes of alcohol and marijuana use including Non-Use (47%), Moderate Alcohol Use (28%), Moderate Alcohol/Increasing Marijuana Use (12%) and High Dual Use (13%). A marijuana only class was not identified. Analyses show negative outcomes in adulthood associated with all three adolescent substance use classes. Compared to the non-use class, all use classes had statistically significantly higher rates of substance dependence. Those in the ‘High Dual Use’ class had the lowest rate of high school graduation. Comparing classes with similar alcohol but different marijuana patterns, the ‘Moderate Alcohol/Increasing Marijuana Use’ class had a statistically significant increased risk of having a criminal justice record and developing substance use dependence in adulthood. Conclusion Among urban youth, heterogeneous patterns of alcohol and marijuana use across adolescence are evident, and these patterns are associated with distinct outcomes in adulthood. These findings suggest a need for targeted education and intervention efforts to address the needs of youth using both marijuana and alcohol, as well as the importance of universal early preventive intervention efforts.

Predicting Alcohol, Cigarette, and Marijuana Use From Preferential Music Consumption.

PubMed

Oberle, Crystal D; Garcia, Javier A

2015-01-01

This study investigated whether use of alcohol, cigarettes, and marijuana may be predicted from preferential consumption of particular music genres. Undergraduates (257 women and 78 men) completed a questionnaire assessing these variables. Partial correlation analyses, controlling for sensation-seeking tendencies and behaviors, revealed that listening to conventional music (pop, country, and religious genres) was negatively correlated with cigarette smoking (p=.001) and marijuana use (p<.001). Additionally, listening to energetic music (rap or hip-hop and soul or funk genres) was positively correlated with marijuana use (p=.004). The only significant predictor of alcohol use was country music, with which it was positively correlated (p=.04). This research suggests an especially harmful influence of energetic music on marijuana use. © The Author(s) 2015.

To evaluate how young adults perceive and compare harms and benefits of marijuana and tobacco products in the context of a legal marijuana market in Colorado. Semi-structured qualitative interviews. Denver, CO, USA. Thirty-two young adults (aged 18-26 years) who used tobacco/marijuana/vaporizers. Semi-structured interviews addressed perceived harms and benefits of various tobacco and marijuana products and personal experiences with these products. Young adults evaluated harms and benefits using five dimensions: (1) combustion-smoking was considered more harmful than non-combustible products (e.g. e-cigarettes, vaporizers and edibles); (2) potency-edibles and marijuana concentrates were perceived as more harmful than smoking marijuana flower because of potential to receive too large a dose of tetrahydrocannabinol (THC); (3) chemicals-products containing chemical additives were seen as more harmful than 'pure' or 'natural' plant products; (4) addiction-participants recognized physiological addiction to nicotine, but talked primarily about psychological or life-style dependence on marijuana; and (5) source of knowledge-personal experiences, warning labels, campaigns, the media and opinions of product retailers and medical practitioners affected perceptions of harms and benefits. Among young adults in Colorado, USA, perceived harms and benefits of tobacco and marijuana include multiple dimensions. Health educational campaigns could benefit from addressing these dimensions, such as the potency of nicotine and cannabis concentrates and harmful chemicals present in the organic material of tobacco and marijuana. Descriptors such as 'natural' and 'pure' in the promotion or packaging of tobacco and marijuana products might be misleading. © 2017 Society for the Study of Addiction.

Early alcohol, tobacco and drug use prior to 18 years old are comorbid and correlated. This study included 6239 adults with major depressive disorder (MDD) in the past year and 72,010 controls from the combined data of 2013 and 2014 National Survey on Drug Use and Health (NSDUH). To deal with multicollinearity existing among 17 variables related to early alcohol, tobacco and drug use prior to 18 years old, we used principal component analysis (PCA) to infer PC scores and then use weighted multiple logistic regression analyses to estimate the associations of potential factors and PC scores with MDD. The odds ratios (ORs) with 95% confidence intervals (CIs) were estimated. The overall prevalence of MDD was 6.7%. The first four PCs could explain 57% of the total variance. Weighted multiple logistic regression showed that PC 1 (a measure of psychotherapeutic drugs and illicit drugs other than marijuana use), PC 2 (a measure of cocaine and hallucinogens), PC 3 (a measure of early alcohol, cigarettes, and marijuana use), and PC 4 (a measure of cigar, smokeless tobacco use and illicit drugs use) revealed significant associations with MDD (OR = 1.12, 95% CI = 1.08-1.16, OR = 1.08, 95% CI = 1.04-1.12, OR = 1.13, 95% CI = 1.07-1.18, and OR = 1.15, 95% CI = 1.09-1.21, respectively). In conclusion, PCA can be used to reduce the indicators in complex survey data. Early alcohol, tobacco and drug use prior to 18 years old were found to be associated with increased odds of adult MDD.

In the United States, many states have established minimum legal purchase ages for electronic nicotine delivery systems (ENDS) to ban adolescent purchases, but these policies may also affect other related substance use. We explore whether ENDS are substitutes or complements for cigarettes, cigars, smokeless tobacco, and marijuana among adolescents by using variation in state-level implementation of ENDS age purchasing restrictions. We linked data on ENDS age purchasing restrictions to state- and year-specific rates of adolescent tobacco and marijuana use in 2007-2013 from the Youth Risk Behavior Surveillance System. This data provides a nationally representative sample of adolescents who attend public and private schools. We performed a fixed effect regression analysis exploring the influence of ENDS age purchasing restrictions on outcomes of tobacco use and marijuana use, controlling for state and year fixed characteristics, age-race cohorts, cigarette excise taxes, and cigarette indoor use restrictions. For cigarette use, we separate our results into cigarette use frequency. We found causal evidence that ENDS age purchasing restrictions increased adolescent regular cigarette use by 0.8 percentage points. ENDS age purchasing restrictions were not associated with cigar use, smokeless tobacco use, or marijuana use. We document a concerning trend of cigarette smoking among adolescents increasing when ENDS become more difficult to purchase. Copyright © 2016 Elsevier Inc. All rights reserved.

Although the concepts of harmonious and obsessive passion have been productive in explaining why people eagerly engage in such activities as sports, Internet use, and gambling, previous research has not yet extended these models to explain alcohol and marijuana use among college students. The current research was conducted to clarify the relationships among harmonious and obsessive passion, alcohol and marijuana use, and negative consequences. Two studies were conducted using online assessments. In Study 1, 748 heavy drinking college students (58% female) were recruited and completed measures of passion for drinking alcohol, alcohol use, and alcohol-related negative consequences. In Study 2, 352 regular marijuana-using students (54% female) were recruited and completed assessments of marijuana passion, marijuana use, and marijuana-related consequences. Study 1 found that among heavy drinking college students, harmonious passion was a stronger predictor of increased consumption than was obsessive passion, whereas obsessive passion was a stronger predictor of alcohol-related problems than was harmonious passion. Study 2 revealed similar findings with regard to harmonious passion predicting marijuana consumption; however, unlike Study 1, no significant difference between the passions was found in predicting marijuana-related problems. This research provides a novel perspective on motivation for alcohol and marijuana use. Findings suggest that understanding the locus of young adults' passion for substance use may be helpful in identifying those who are likely to develop a substance use disorder and therefore may be the most in need of assistance and intervention.

Parental Divorce and Family History of Alcohol Disorder: Associations with Young Adults' Alcohol Problems, Marijuana Use, and Interpersonal Relations.

2018-06-01

This study used prospective data from 706 young adults to evaluate the impact of parental divorce and family history of alcoholism (FH+) on the outcomes of offspring alcohol problems, marijuana use, and interpersonal relationships with parents. Assessments of parental divorce were based on parent reports, and young adult outcomes were collected from an offspring cohort (n = 706; X age = 33.25 years; females = 53%) via computer-based individual interviews (CAPI and ACASI). Family history of alcohol disorders for parents was based on assessments by mothers, fathers, and young adults. Parental divorce significantly predicted marijuana use but not alcohol problems. Maternal, but not paternal, alcoholism also significantly predicted marijuana use. Two-way interactions indicated that sex moderated several of the relationships. For example, among those with divorced parents, daughters reported higher levels of conflict with fathers than sons, and sons reported lower levels of maternal support than daughters. Paternal alcoholism was also associated with higher levels of alcohol problems among sons relative to daughters. There was also a significant 2-way interaction between divorce status and maternal alcoholism indicating that young adults who experienced both maternal alcoholism and parental divorce had the highest levels of marijuana use. These findings highlight the role that parental divorce and FH+ have on alcohol problems, marijuana use, and interpersonal relationships in young adulthood, and how sex may moderate some of these more nuanced relationships.

To estimate the cumulative probability of occurrence of first use of alcohol and tobacco, and the risk of transition to illegal drugs (marijuana, cocaine, and heroine, among others), in adolescents and young adults, in Morelos State, Mexico. A cross-sectional study was conducted during schoolyear 1998-1999, among 13 293 students aged 11-24 years, selected from public schools by probabilistic multistage sampling. Data were collected on sociodemographic, health status, and substance abuse variables, using a validated self-applied questionnaire. Data were restructured to assemble a synthetic cohort for discrete time survival analysis. Associations were assessed with hazard rates and 95% confidence intervals obtained by means of multivariate Cox regression models. Sixty percent of males started drinking alcohol at 17 years of age, and smoking tobacco at 18 years of age, on average. Women started using alcohol and tobacco one year after men. Utilization of illicit drugs occurred at 19 years of age on average in 5% of women and 13% of men. Nine out of every 100 illicit drug users started directly using illicit drugs without previous use of alcohol and/or tobacco. In general, alcohol or tobacco users were at greater risk of starting drug use than nonusers (RR=6.72; 95 % confidence interval [CI]=4.13-10.93). Study findings suggest that interventions to decrease drug abuse should go together with efforts to delay initiation of alcohol and tobacco use. The innovative method used in this study yields epidemiologic evidence relating early use of alcohol and tobacco with initiation of illegal drugs in Mexican students.

The impact of alcohol consumption and marijuana use on high school graduation.

In this study we use data from the National Longitudinal Survey of Youth (NLSY) to estimate the relationship between high school graduation, and alcohol and marijuana use among high school students. We also estimate the demand determinants for each of these substances. Our results show that there are significant adverse effects of alcohol and marijuana use on high school graduation. In particular, increases in the incidence of frequent drinking, liquor and wine consumption, and frequent marijuana use, significantly reduce the probability of high school graduation. Our results also show that beer taxes, liquor prices and marijuana decriminalization have a significant impact on the demand for these substances. These findings have important policy implications. A ten percent increase in beer taxes, reduces alcohol consumption among high school students, which in turn raises the probability of high school graduation by about three percent. A 1 percent increase in liquor prices raises the probability of high school graduation by over 1 percent. Raising the minimum drinking age for liquor also reduces liquor and wine consumption, and thus, improves the probability of high school graduation. Although the relationship between marijuana decriminalization and marijuana use is not significant, decriminalization is found to reduce the probability of becoming a frequent drinker. This result suggests that marijuana use and frequent drinking are substitute activities. Illicit substance abuse reduces the rate of high school completion, reduces expected future earnings and creates potential health problems. Thus, high-school-based preventive programs which discourage alcohol consumption and marijuana use are highly recommended, in order to alleviate these problems.

Among high-risk youth, those who may be at increased risk for adverse alcohol and other drug (AOD) use outcomes may benefit from targeted prevention efforts; how youth acquire AOD may provide an objective means of identifying youth at elevated risk. We assessed how youth acquired alcohol and marijuana (purchasing vs. other means), demographics, AOD behaviors/consequences, and environment among adolescents referred to a diversion program called Teen Court (N = 180) at two time points (prior to the program and 180 days from baseline). Participants were predominantly White and Hispanic/Latino(a). In cross-sectional analyses among alcohol and marijuana users, purchasing marijuana was associated with more frequent marijuana use and consequences, time spent around teens who use marijuana, higher likelihood of substance use disorders, and lower resistance self-efficacy compared to non-purchasers. Teens who purchased both alcohol and marijuana experienced similar outcomes to those who purchased only marijuana, and also reported more frequent and higher quantity of drinking, greater alcohol-related consequences, time spent around teens who use other drugs, and prescription drug misuse. Longitudinally, purchasing alcohol and marijuana at baseline was associated with more frequent and higher quantity of drinking compared to non-purchasers at follow-up. Marijuana only purchasers had a greater likelihood of substance use disorders at follow-up compared to non-purchasers. In an era where drinking is commonplace and attitudes towards marijuana use are becoming more tolerant, it is essential to evaluate how accessibility to AOD and subsequent purchasing behaviors affect youth consumption and intervene accordingly to prevent future consequences.

BACKGROUND Marijuana use is increasingly prevalent among young adults. While research has found adverse effects associated with marijuana use within experimentally controlled laboratory settings, it is unclear how recreational marijuana use affects day-to-day experiences in users. The present study sought to examine the effects of marijuana use on within-person changes in impulsivity and interpersonal hostility in daily life using smartphone administered assessments. METHODS Forty-three participants with no substance dependence reported on their alcohol consumption, tobacco use, recreational marijuana use, impulsivity, and interpersonal hostility over the course of 14 days. Responses were analyzed using multilevel modeling. RESULTS Marijuana use was associated with increased impulsivity on the same day and the following day relative to days when marijuana was not used, independent of alcohol use. Marijuana was also associated with increased hostile behaviors and perceptions of hostility in others on the same day when compared to days when marijuana was not used. These effects were independent of frequency of marijuana use or alcohol use. There were no significant effects of alcohol consumption on impulsivity or interpersonal hostility. CONCLUSIONS Marijuana use is associated with changes in impulse control and hostility in daily life. This may be one route by which deleterious effects of marijuana are observed for mental health and psychosocial functioning. Given the increasing prevalence of recreational marijuana use and the potential legalization in some states, further research on the potential consequences of marijuana use in young adults’ day-to-day life is warranted.

We report whether the etiology underlying associations of childhood ADHD with adolescent alcohol and marijuana involvement is consistent with causal relationships or shared predispositions, and whether it differs by gender. In three population-based twin samples (N = 3762; 64% monozygotic), including one oversampling females with ADHD, regressions were conducted with childhood inattentive or hyperactive-impulsive symptoms predicting alcohol and marijuana outcomes by age 17. To determine whether ADHD effects were consistent with causality, twin difference analyses divided effects into those shared between twins in the pair and those differing within pairs. Adolescents with more severe childhood ADHD were more likely to initiate alcohol and marijuana use earlier, escalate to frequent or heavy use, and develop symptoms. While risks were similar across genders, females with more hyperactivity-impulsivity had higher alcohol consumption and progressed further toward daily marijuana use than did males. Monozygotic twins with more severe ADHD than their co-twins did not differ significantly on alcohol or marijuana outcomes, however, suggesting a non-causal relationship. When co-occurring use of other substances and conduct/oppositional defiant disorders were considered, hyperactivity-impulsivity remained significantly associated with both substances, as did inattention with marijuana, but not alcohol. Childhood ADHD predicts when alcohol and marijuana use are initiated and how quickly use escalates. Shared familial environment and genetics, rather than causal influences, primarily account for these associations. Stronger relationships between hyperactivity-impulsivity and heavy drinking/frequent marijuana use among adolescent females than males, as well as the greater salience of inattention for marijuana, merit further investigation.

To examine the associations between youth poly-tobacco use and substance use disorders. Analysis of data from the 2007-11 US National Survey on Drug Use and Health. Randomly selected, household-dwelling adolescents from the non-institutionalized, civilian population of the United States. A total of 91 152 adolescents (aged 12-17 years). Logistic regression models were used to examine the associations between type of tobacco user (non-user, users of alternative tobacco products only, users of cigarettes only and users of cigarettes plus alternative tobacco products) with past year alcohol, marijuana or other illicit drug use disorders, adjusting for demographic and social variables. Compared with non-users of tobacco, the greatest risk for substance use disorders was among users of cigarettes plus alternative tobacco products [alcohol disorder adjusted odds ratio (aOR) = 18.3, 95% confidence interval (CI) = 16.2-20.6; marijuana disorder aOR = 37.2, 95% CI = 32.5-42.7; other drug disorder aOR = 18.4, 95% CI = 15.4-21.8], followed by users of cigarettes only (alcohol disorder aOR = 9.6, 95% CI = 8.8-10.6; marijuana disorder aOR = 20.4, 95% CI = 18.1-23.0; other drug disorder aOR = 9.4, 95% CI = 7.8-11.4), then users of alternative tobacco products only (alcohol disorder aOR = 8.1, 95% CI = 6.7-9.6; marijuana disorder aOR = 9.2, 95% CI = 7.5-11.4; other drug disorder aOR = 3.2, 95% CI = 2.4-4.3). Tobacco use in adolescence is associated with higher rates of substance use disorders across all tobacco users, especially among those who use cigarettes plus other tobacco products. © 2014 Society for the Study of Addiction.

This study assessed differences in individual tobacco product use between past month marijuana users and nonusers, and trends in overall tobacco use and use of specific tobacco products among marijuana users. Data were obtained from 378 459 adults participating in the 2003-2012 National Survey on Drug Use and Health, a cross-sectional, household interview survey conducted annually. Data from the most recent 2 years (2011-2012) were used to assess differences in the prevalence of various tobacco products by past month marijuana status. Data from all years were used to assess historical trends in overall tobacco use, and use of cigarettes, cigars, and blunts among marijuana users; trend significance was assessed using orthogonal polynomials. From 2011-2012, the prevalence of any past month tobacco use among the 9727 past month marijuana users was 68.6% excluding blunts, and 78.3% including blunts (vs. 25.3% for nonusers, P < .0001); 77.3% of past month marijuana users reported past month combusted tobacco use (vs. 23.4% of non-MJ users, P < .0001). By product, 60.1% of past month marijuana users reported past month cigarette use, 42.0% reported past month blunt use, and 20.6% reported past month cigar use. Overall, adjusted trends in past month cigarette use decreased, while trends in past month blunt use increased; cigar use did not change. Tobacco use is highly prevalent among adult marijuana users and represents an important potential comorbidity of marijuana use. In light of increasing policies legalizing marijuana, it is critical to monitor changes in overall and specific tobacco product use. © The Author 2015.

We analyze marijuana use by college undergraduates before and after legalization of recreational marijuana. Using survey data from the National College Health Assessment, we show that students at Washington State University experienced a significant increase in marijuana use after legalization. This increase is larger than would be predicted by national trends. The change is strongest among females, Black students, and Hispanic students. The increase for underage students is as much as for legal-age students. We find no corresponding changes in the consumption of tobacco, alcohol, or other drugs.

Alcohol and marijuana are the two most abused substances in US colleges. However, research on the combined influence (cross sectional or longitudinal) of these substances on academic performance is currently scant. Data were derived from the longitudinal 2-year Brain and Alcohol Research in College Students (BARCS) study including 1142 freshman students who completed monthly marijuana use and alcohol consumption surveys. Subjects were classified into data-driven groups based on their alcohol and marijuana consumption. A linear mixed-model (LMM) was employed using this grouping factor to predict grade point average (GPA), adjusted for a variety of socio-demographic and clinical factors. Three data-driven clusters emerged: 1) No/low users of both, 2) medium-high alcohol/no-low marijuana, and 3) medium-high users of both substances. Individual cluster derivations between consecutive semesters remained stable. No significant interaction between clusters and semester (time) was noted. Post-hoc analysis suggest that at the outset, compared to sober peers, students using moderate to high levels of alcohol and low marijuana demonstrate lower GPAs, but this difference becomes non-significant over time. In contrast, students consuming both substances at moderate-to-high levels score significantly lower at both the outset and across the 2-year investigation period. Our follow-up analysis also indicate that when students curtailed their substance use over time they had significantly higher academic GPA compared to those who remained stable in their substance use patterns over the two year period. Overall, our study validates and extends the current literature by providing important implications of concurrent alcohol and marijuana use on academic achievement in college.

Multiple theories suggest mechanisms by which the use of alcohol and drugs during adolescence could dampen growth in psychosocial maturity. However, scant empirical evidence exists to support this proposition. The current study tested whether alcohol and marijuana use predicted suppressed growth in psychosocial maturity among a sample of male serious juvenile offenders (n = 1,170) who were followed from ages 15 to 21 years. Alcohol and marijuana use prospectively predicted lower maturity 6 months later. Moreover, boys with the greatest increases in marijuana use showed the smallest increases in psychosocial maturity. Finally, heterogeneity in the form of age-related alcohol and marijuana trajectories was related to growth in maturity, such that only boys who decreased their alcohol and marijuana use significantly increased in psychosocial maturity. Taken together, these findings suggest that patterns of elevated alcohol and marijuana use in adolescence may suppress age-typical growth in psychosocial maturity from adolescence to young adulthood, but that effects are not necessarily permanent, because decreasing use is associated with increases in maturity.

Alcohol, tobacco and marijuana are the most common drugs used by adolescents. There is evidence of co-occurrence of alcohol use by young people with taking other problem behaviors, little is known about the causes of drinking depending on the type and severity of different substances use. Aim of the study is to find differences in the structure and the rank of drinking motives among people who smoke cigarettes or use marijuana. The study was carried out on a nationwide sample of 1411 in mean age 17.7 years (53.3% girls) as a part of next series of HBSC study (Health Behaviour in School aged Children) conducted in 2010 .To investigate reasons for alcohol use, research instrument DMQ-R (Drinking Motives Questionnaire-Revised) was used. Questions about currently tobacco smoking and marijuana or, hashish use during last year were also asked. One-way ANOVA with post-hoc test Scheffe were used for analysis. Results: The highest means were noticed in the dimension of social motives and they differed significantly due to smoking (F (2, 1170) = 35.76, p <0.001) and marijuana use (F (2, 1.139) = 30.73, p <0.001). Regular smokers have obtained lower mean (M = 61.2, SD = 25.2) than frequently marijuana users (M = 65.9, SD = 25.1). Conformity motives were the weakest motives of drinking among tobacco or marijuana users. Significant differences due to the type and frequency of substance use occurred only in the groups were taking into account tobacco smoking, (F (2,1176)= 4.25, p <0.05). Differences of the levels of motivation to deal with problems (coping motives) were obtained due to tobacco smoking (F (2,1172) = 44.20, p <0.001) and marijuana use (F (2, 1143) = 9.18, p <0.001). Regular smokers were more pointed on the negative intrinsic motivation (M = 38.1, SD = 29.4) than marijuana users (M = 33.5, SD = 29.6). Means in terms of motivation for enhancement also differed in the groups taking into account tobacco smoking (F (2,1174) = 30.63, p <0.001) and cannabis use (F(2

Using data about members of a midwestern American Indian reservation in eight focus groups that were conducted like "talking circles," the authors describe the participants' (N = 49) views of the current use and abuse of tobacco, alcohol, and other drugs. Results indicate that the use of tobacco is pervasive; that the use of alcohol and other drugs, especially marijuana and oxycodone, are problems on this reservation because they are detrimental to health and well-being; and appropriate, available, and accessible treatment is scarce, nonexistent, or underfunded. Culturally sensitive substance abuse treatment and increased funding for treatment are major health issues for this population.

Introduction Driving while impaired (DWI) increases the risk of a motor vehicle crash by impairing performance. Few studies have examined the prevalence and predictors of marijuana, alcohol, and drug specific DWI among emerging adults. Methods The data from wave 3 (W3, high-school seniors, 2012, N=2407) and wave 4 (W4, one year after high school, N=2178) of the NEXT Generation Health Study with a nationally-representative cohort. W4 DWI (≥1 day of past 30 days) was specified for alcohol-specific, marijuana-specific, alcohol/marijuana-combined, illicit drug-related DWI. Multinomial logistic regression models estimated the association of W4 DWI with W3 covariates (perceived peer/parent influence, drinking/binge drinking, marijuana/illicit drug use), and W4 environmental-status variables (work/school/residence) adjusting for W3 overall DWI, demographic and complex-survey variables. Results Overall DWI prevalence from W3 to W4 changed slightly (14% to 15%). W4 DWI consisted of 4.34% drinking-specific, 5.02% marijuana-specific, 2.41% drinking/marijuana-combined, and 3.37% illicit drug-related DWI. W3 DWI was significantly associated with W4 alcohol-related and alcohol/marijuana-combined DWI, but not other DWI. W3 marijuana use, binge drinking, and illicit drug use were positively associated with W4 marijuana-specific, alcohol/marijuana-combined, and illicit drug-related DWI respectively. W3 friend drunkenness and marijuana use were positively associated with W4 alcohol-specific and marijuana-related DWI respectively. W3 peer marijuana use was negatively associated with W4 alcohol-specific DWI. Conclusions Driving under the influence of alcohol, marijuana, and illicit drugs is a persistent, threatening public health concern among emerging US adults. High-school seniors’ binge drinking as well as regular alcohol drinking and marijuana/illicit drug use were independently associated with respective DWI one year after high school.

Young adults are increasingly interacting with their peer groups online through social networking sites. These online interactions may reinforce or escalate alcohol and other drug (AOD) use as a result of more frequent and continuous exposure to AOD promotive norms; however, the influence of young adults' virtual networks on AOD use remains untested. The purpose of this study was to examine the association between the presence of AOD use content in online social networking, perceived norms (online norms regarding AOD use and anticipated regret with AOD use postings), and alcohol and marijuana use in a sample of 18- to 24-year-olds. Using an adapted web version of respondent-driven sampling (webRDS), we recruited a sample of 18- to 24-year-olds (N = 3,448) in the United States. Using multivariate regression, we explored the relationship between past-30-day alcohol and marijuana use, online norms regarding AOD use, peer substance use, and online and offline peer support. Alcohol use was associated with more alcohol content online. Anticipated regret and online peer support were associated with less alcohol use. Anticipated regret was negatively associated with marijuana use. Peer AOD use was positively associated with both alcohol and marijuana use. Peers play an important role in young adult alcohol and marijuana use, whether online or in person. Our findings highlight the importance of promoting online network-based AOD prevention programs for young adults in the United States.

Driving after marijuana use increases the risk of a motor vehicle crash. Understanding this behavior among young drivers and how it may differ from alcohol-related driving behaviors could inform prevention efforts. To describe the prevalence, sex differences, and risk factors associated with underage college students' driving after using marijuana, driving after drinking alcohol, or riding with a driver using these substances. Cross-sectional telephone survey of a random sample of 315 first-year college students (aged 18-20 years) from 2 large public universities, who were participating in an ongoing longitudinal study. At recruitment, 52.8% of eligible individuals consented to participate; retention was 93.2% one year later when data for this report were collected. Self-reported past-28-day driving after marijuana use, riding with a marijuana-using driver, driving after alcohol use, and riding with an alcohol-using driver. In the prior month, 20.3% of students had used marijuana. Among marijuana-using students, 43.9% of male and 8.7% of female students drove after using marijuana (P < .001), and 51.2% of male and 34.8% of female students rode as a passenger with a marijuana-using driver (P = .21). Most students (65.1%) drank alcohol, and among this group 12.0% of male students and 2.7% of female students drove after drinking (P = .01), with 20.7% and 11.5% (P = .07), respectively, reporting riding with an alcohol-using driver. Controlling for demographics and substance use behaviors, driving after substance use was associated with at least a 2-fold increase in risk of being a passenger with another user; the reverse was also true. A 1% increase in the reported percentage of friends using marijuana was associated with a 2% increased risk of riding with a marijuana-using driver (95% CI, 1.01-1.03). Among students using any substances, past-28-day use of only marijuana was associated with a 6.24-fold increased risk of driving after substance use

Objective: The aim of this study was to examine how reasons for substance use at age 18 relate to alcohol and marijuana use at ages 18 and 35 and to symptoms of alcohol use disorder and marijuana use disorder at age 35. Method: Bivariate correlation and multivariate regression analyses were conducted to examine the prediction of substance use and misuse by social/recreational, coping with negative affect, compulsive, and drug effect reasons for alcohol and marijuana use. Control variables included gender, race/ethnicity, parent education, and previous substance use (for age 35 outcomes). Results: Social/recreational, coping, and drug effect reasons for drinking predicted symptoms of alcohol use disorder 17 years later. Reasons for marijuana use were generally associated only with concurrent marijuana use; an exception was that drug effect reasons predicted marijuana use disorder at age 35. Conclusions: The long-term longitudinal predictive power of reasons for alcohol use (and, to a lesser extent, for marijuana use) suggests that adolescents' self-reported reasons, in particular those involving regulating emotions and experiences, may be early risk factors for continued use and misuse of substances into adulthood.

Cigarettes, cigars, and marijuana have generally been studied in isolation yet their use does not occur in isolation. Focus on cigarette smoking may overstate the observation that African American youth and young adults are less likely to smoke any combustible product compared with their white counterparts. Assessing cigarette, cigar, and marijuana use trends may help identify the extent of this difference. Data from the 2002-2012 National Survey on Drug Use and Health (N = 25 541 to N = 28 232) were used to investigate past 30-day cigarette, cigar, and marijuana use trends among African American and white youth (12-17) and young adults (18-25). Logistic regressions assessed trends in combustible tobacco (cigarettes and cigars) and marijuana use, alone and in combination. From 2002-2012, the absolute difference in cigarette smoking prevalence between African American and white youth (9.6%-4.2%) and young adults (19.0%-10.5%) narrowed. Any combustible tobacco/marijuana use was significantly lower among African Americans than whites but, relative to cigarettes, the absolute difference was much smaller among youth (7.2%-2.2%) and young adults (15.8%-5.6%). Among any combustible tobacco/marijuana users, using two or more substances ranged from 31.4% to 40.3% among youth and 29.1% to 39.8% among young adults. Any combustible tobacco/marijuana use trends suggest the smoking prevalence difference between African American and white youth and young adults is real, but less pronounced than when assessing cigarette smoking alone. Policies and programs addressing smoking behaviors may benefit from broadening focus to monitor and address cigar and marijuana use as well. Trends in any use of cigarettes, cigars, and/or marijuana suggest the difference in smoking prevalence between African American and white youth and young adults is real, but less pronounced than when cigarette smoking is assessed alone. In 2012, more than 10% of African American and white youth, more than a

Marijuana is the most commonly used illegal drug in the United States. In some subcultures, it is widely perceived to be harmless. Although the carcinogenic properties of marijuana smoke are similar to those of tobacco, no epidemiological studies of the relationship between marijuana use and head and neck cancer have been published. The relationship between marijuana use and head and neck cancer was investigated by a case-control study of 173 previously untreated cases with pathologically confirmed diagnoses of squamous cell carcinoma of the head and neck and 176 cancer-free controls at Memorial Sloan-Kettering Cancer Center between 1992 and 1994. Epidemiological data were collected by using a structured questionnaire, which included history of tobacco smoking, alcohol use, and marijuana use. The associations between marijuana use and head and neck cancer were analyzed by Mantel-Haenszel methods and logistic regression models. Controlling for age, sex, race, education, alcohol consumption, pack-years of cigarette smoking, and passive smoking, the risk of squamous cell carcinoma of the head and neck was increased with marijuana use [odds ratio (OR) comparing ever with never users, 2.6; 95% confidence interval (CI), 1.1-6.6]. Dose-response relationships were observed for frequency of marijuana use/day (P for trend <0.05) and years of marijuana use (P for trend <0.05). These associations were stronger for subjects who were 55 years of age and younger (OR, 3.1; 95% CI, 1.0-9.7). Possible interaction effects of marijuana use were observed with cigarette smoking, mutagen sensitivity, and to a lesser extent, alcohol use. Our results suggest that marijuana use may increase the risk of head and neck cancer with a strong dose-response pattern. Our analysis indicated that marijuana use may interact with mutagen sensitivity and other risk factors to increase the risk of head and neck cancer. The results need to be interpreted with some caution in drawing causal inferences

Adolescents with attention deficit/hyperactivity disorder (ADHD) are at an increased risk for substance use but the pathways through which this risk emerges are insufficiently understood. Tobacco, alcohol, and marijuana outcomes were compared between adolescents diagnosed with ADHD in early childhood (N = 113) and demographically similar controls (N = 65). Participants were assessed from age 5 until age 18. A comprehensive history of adolescent substance use was compiled for each participant and growth in ADHD and conduct disorder (CD) were modeled as they related to substance use outcomes. Results indicated that when compared with controls, adolescents with ADHD were more likely to try cigarettes, initiate alcohol use at early ages, and smoke marijuana more frequently. Furthermore, adolescents with ADHD were 4 to 5 times more likely than controls to escalate to heavy cigarette and marijuana use after trying these substances once. Adolescents with ADHD who escalated to heavy use patterns were more likely to display early cigarette use and marked problems with family members, but displayed fewer peer problems. There was evidence of baseline effects (latent intercept, measured at age 5) for both ADHD and CD on substance use outcomes. Furthermore, growth in ADHD symptoms accounted for much of the growth in CD symptoms, and consequently, escalating CD symptoms in childhood (latent slope) were viewed as a mediator of the relationship between ADHD and cigarette and marijuana use. Maternal drinking in early childhood was the strongest predictor of early adolescent alcohol use. These findings are discussed with respect to the role of ADHD in the development of adolescent risk outcomes.

The purpose of the present study was to assess the effects of low doses of marijuana and alcohol, and their combination, on visual search at intersections and on general driving proficiency in the City Driving Test. Sixteen recreational users of alcohol and marijuana (eight males and eight females) were treated with these substances or placebo according to a balanced, 4-way, cross-over, observer- and subject-blind design. On separate evenings, subjects received weight-calibrated doses of THC, alcohol or placebo in each of the following treatment conditions: alcohol placebo + THC placebo, alcohol + THC placebo, THC 100 &mgr;g/kg + alcohol placebo, THC 100 &mgr;g/kg + alcohol. Alcohol doses administered were sufficient for achieving a blood alcohol concentration (BAC) of about 0.05 g/dl. Initial drinking preceded smoking by one hour. The City Driving Test commenced 15 minutes after smoking and lasted 45 minutes. The test was conducted over a fixed route within the city limits of Maastricht. An eye movement recording system was mounted on each subject's head for providing relative frequency measures of appropriate visual search at intersections. General driving quality was rated by a licensed driving instructor on a shortened version of the Royal Dutch Tourist Association's Driving Proficiency Test. After placebo treatment subjects searched for traffic approaching from side streets on the right in 84% of all cases. Visual search frequency in these subjects did not change when they were treated with alcohol or marijuana alone. However, when treated with the combination of alcohol and marijuana, the frequency of visual search dropped by 3%. Performance as rated on the Driving Proficiency Scale did not differ between treatments. It was concluded that the effects of low doses of THC (100 &mgr;g/kg) and alcohol (BAC < 0.05 g/dl) on higher-level driving skills as measured in the present study are minimal.

Objective Little is known about what may distinguish effective and ineffective group interventions. Group motivational interviewing (MI) is a promising intervention for adolescent alcohol and other drug (AOD) use; however, the mechanisms of change for group MI are unknown. One potential mechanism is change talk, which is client speech arguing for change. The present study describes the group process in adolescent group MI and effects of group-level change talk on individual alcohol and marijuana outcomes. Method We analyzed 129 group session audio recordings from a randomized clinical trial of adolescent group MI. Sequential coding was performed using the Motivational Interviewing Skill Code (MISC) and the CASAA Application for Coding Treatment Interactions (CACTI) software application. Outcomes included past-month intentions, frequency, and consequences of alcohol and marijuana use, motivation to change, and positive expectancies. Results Sequential analysis indicated that facilitator open-ended questions and reflections of change talk (CT) increased group CT. Group CT was then followed by more CT. Multilevel models accounting for rolling group enrollment revealed group CT was associated with decreased alcohol intentions, alcohol use and heavy drinking three months later; group sustain talk was associated with decreased motivation to change, increased intentions to use marijuana, and increased positive alcohol and marijuana expectancies. Conclusions Facilitator speech and peer responses each had effects on change and sustain talk in the group setting, which was then associated with individual changes. Selective reflection of CT in adolescent group MI is suggested as a strategy to manage group dynamics and increase behavioral change. PMID:25365779

Background: Marijuana is often smoked via a filterless cigarette and contains similar chemical makeup as smoked tobacco. There are few publications describing usage patterns and respiratory risks in older adults or in those with chronic obstructive pulmonary disease (COPD). Methods: A cross-sectional analysis of current and former tobacco smokers from the Subpopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS) study assessed associations between marijuana use and pulmonary outcomes. Marijuana use was defined as never, former (use over 30 days ago), or current (use within 30 days). Respiratory health was assessed using quantitative high-resolution computed tomography (HRCT) scans, pulmonary function tests and questionnaire responses about respiratory symptoms. Results: Of the total 2304 participants, 1130 (49%) never, 982 (43%) former, and 192 (8%) current marijuana users were included. Neither current nor former marijuana use was associated with increased odds of wheeze (odds ratio [OR] 0.87, OR 0.97), cough (OR 1.22; OR 0.93) or chronic bronchitis (OR 0.87; OR 1.00) when compared to never users. Current and former marijuana users had lower quantitative emphysema ( P =0.004, P =0.03), higher percent predicted forced expiratory volume in 1 second (FEV 1 %) ( P <0.001, P <0.001), and percent predicted forced vital capacity (FVC%) ( p <0.001, P <0.001). Current marijuana users exhibited higher total tissue volume ( P =0.003) while former users had higher air trapping ( P <0.001) when compared to never marijuana users. Conclusions: Marijuana use was found to have little to no association with poor pulmonary health in older current and former tobacco smokers after adjusting for covariates. Higher forced expiratory volume in 1 second (FEV 1 ) and forced vital capacity (FVC) was observed among current marijuana users. However, higher joint years was associated with more chronic bronchitis symptoms (e.g., wheeze), and this study cannot determine if long

Although a robust literature documents a positive association between alcohol and intimate partner violence (IPV), there is limited temporal research on this relation. Moreover, the role of marijuana in influencing IPV has been mixed. Thus, the primary aim of the current study was to examine the temporal relationship between alcohol and marijuana use and dating violence perpetration. A secondary aim was to examine whether angry affect moderated the temporal relation between alcohol and marijuana use and IPV perpetration. Participants were college women who had consumed alcohol in the previous month and were in a dating relationship (N = 173). For up to 90 consecutive days, women completed daily surveys that assessed their alcohol use, marijuana use, angry affect (anger, hostility, and irritation), and violence perpetration (psychological and physical). On alcohol use days, marijuana use days, and with increases in angry affect, the odds of psychological aggression increased. Only alcohol use days and increases in angry affect increased the odds of physical aggression. Moreover, the main effects of alcohol and marijuana use on aggression were moderated by angry affect. Alcohol was positively associated with psychological and physical aggression when angry affect was high, but was unrelated to aggression when angry affect was low. Marijuana use was associated with psychological aggression when angry affect was high. Findings advance our understanding of the proximal effect of alcohol and marijuana use on dating violence, including the potential moderating effect of angry affect on this relation.

Few studies investigating the validity of marijuana use have used samples of truant youth. In the current study, self-reports of marijuana use are compared with urine test results for marijuana to identify marijuana underreporting among adolescents participating in a longitudinal Brief Intervention for drug-involved truant youth. It was hypothesized that marijuana underreporting would be associated with alcohol underreporting and engaging in sexual risk behaviors. The results indicated marijuana underreporting was significantly associated with self-denial of alcohol use, but not associated with sexual risk behavior. Also, there was an age effect in marijuana use underreporting such that younger truant youth were more likely to underreport marijuana use, compared to older truant youth. Implications for policy and future research are discussed. PMID:26478691

Substance use is partially driven by habitual processes that occur automatically in response to environmental cues and may be central to users' identities. This study was designed to validate the Self-Report Habit Index (SRHI) for assessing habitual marijuana, alcohol, cigarette, and e-cigarette use. We examined the SRHI's psychometrics in separate samples of adult marijuana (Ns = 189;170), alcohol (Ns = 100;133), cigarette (Ns = 58;371), and e-cigarette (N = 239) users. A 6-item, single-factor solution evidenced good fit across substances (CFI marijuana/alcohol/cigarettes/e-cigarettes = 0.996/0.997/0.996/0.994, RMSEA = 0.046/0.047/0.067/0.068, SRMR = 0.017/0.017/0.010/0.015) and internal consistency (α = 0.88/0.94/0.95/0.91). The SRHI was scalar invariant for sex and race. However, independent-samples t-tests indicated only that women endorsed stronger habitual e-cigarette use and that men endorsed stronger habitual marijuana use. The SRHI also was scalar invariant by product type in dual-users (cigarettes/e-cigarettes[N = 371]; alcohol/cigarettes [n = 58]), although differences in habit strength only were observed for cigarettes versus e-cigarettes, with dual-users reporting stronger habitual cigarette use. Finally, the SRHI predicted frequency of marijuana, alcohol, cigarette, and e-cigarette use (n p 2 [marijuana/alcohol/cigarettes/e-cigarettes] = 0.37/0.48/0.31/0.17) and quantity of alcohol and cigarette use (n p 2  = 0.43/0.33). The SRHI is a psychometrically sound measure of adults' habitual substance use. The SRHI detected mean differences by sex and substance type and predicted the frequency of using each substance. Future research should determine if the SRHI is appropriate for use with other substances or age groups (e.g., adolescents), how it relates to task-based, behavioral measures of habit strength, and the degree to which habit predicts the development or maintenance of addiction.

[Pros and cons of legalizing marijuana].

PubMed

2014-04-01

There are already several countries that have accepted marijuana as a soft drug, separating it from more dangerous ones. Yarious therapeutic properties have even been attributed to its use. Others, however, think that its use should be prohibited due to the mental interference and behavioral changes produced either by its occasional use as well as the permanent mental damage linked to chronic marijuana use. In order to clarify this divergence of opinions, the scientific literature is reviewed. It is concluded that there is a serious risk, especially for teenagers, associated to chronic marijuana use due to the presence of more frequent psychotic and schizophrenic episodes, which can be permanent, while consumption during pregnancy results in brain damage to the fetus, similar to fetal alcohol syndrome. Scientific research also indicated that smoking marijuana produces an even more severe bronchial damage than tobacco, with risk of lung cancer. In conclusion, the notion that marijuana is a risk-free soft drug is a serious mistake, based on the available conclusive scientific research that shows the opposite.

Animal studies have demonstrated adverse effects of prenatal alcohol exposure on placental development, but few studies have examined these effects in humans. Little is known about effects of prenatal exposure to methamphetamine, marijuana, and cigarette smoking on placental development. Placentas were collected from 103 Cape Coloured (mixed ancestry) pregnant women recruited at their first antenatal clinic visit in Cape Town, South Africa. Sixty-six heavy drinkers and 37 nondrinkers were interviewed about their alcohol, cigarette smoking, and drug use at 3 antenatal visits. A senior pathologist, blinded to exposure status, performed comprehensive pathology examinations on each placenta using a standardized protocol. In multivariable regression models, effects of prenatal exposure were examined on placental size, structure, and presence of infections and meconium. Drinkers reported a binge pattern of heavy drinking, averaging 8.0 drinks/occasion across pregnancy on 1.4 d/wk. 79.6% smoked cigarettes; 22.3% used marijuana; and 17.5% used methamphetamine. Alcohol exposure was related to decreased placental weight and a smaller placenta-to-birthweight ratio. By contrast, methamphetamine was associated with larger placental weight and a larger placenta-to-birthweight ratio. Marijuana was also associated with larger placental weight. Alcohol exposure was associated with increased risk of placental hemorrhage. Prenatal alcohol, drug, and cigarette use were not associated with chorioamnionitis, villitis, deciduitis, or maternal vascular underperfusion. Alcohol and cigarette smoking were associated with a decreased risk of intrauterine passing of meconium, a sign of acute fetal stress and/or hypoxia; methamphetamine, with an increased risk. This is the first human study to show that alcohol, methamphetamine, and marijuana were associated with distinct patterns of pathology, suggesting different mechanisms mediating their effects on placental development. Given the growing

Introduction Cigarettes, cigars, and marijuana have generally been studied in isolation yet their use does not occur in isolation. Focus on cigarette smoking may overstate the observation that African American youth and young adults are less likely to smoke any combustible product compared with their white counterparts. Assessing cigarette, cigar, and marijuana use trends may help identify the extent of this difference. Methods Data from the 2002–2012 National Survey on Drug Use and Health (N = 25 541 to N = 28 232) were used to investigate past 30-day cigarette, cigar, and marijuana use trends among African American and white youth (12–17) and young adults (18–25). Logistic regressions assessed trends in combustible tobacco (cigarettes and cigars) and marijuana use, alone and in combination. Results From 2002–2012, the absolute difference in cigarette smoking prevalence between African American and white youth (9.6%–4.2%) and young adults (19.0%–10.5%) narrowed. Any combustible tobacco/marijuana use was significantly lower among African Americans than whites but, relative to cigarettes, the absolute difference was much smaller among youth (7.2%–2.2%) and young adults (15.8%–5.6%). Among any combustible tobacco/marijuana users, using two or more substances ranged from 31.4% to 40.3% among youth and 29.1% to 39.8% among young adults. Conclusion Any combustible tobacco/marijuana use trends suggest the smoking prevalence difference between African American and white youth and young adults is real, but less pronounced than when assessing cigarette smoking alone. Policies and programs addressing smoking behaviors may benefit from broadening focus to monitor and address cigar and marijuana use as well. Implications Trends in any use of cigarettes, cigars, and/or marijuana suggest the difference in smoking prevalence between African American and white youth and young adults is real, but less pronounced than when cigarette smoking is assessed alone.

Background Youth who are homeless and on their own are among the most marginalized individuals in the United States and face multiple risks, including use of substances. This study investigates how the use of alcohol, cigarettes, and marijuana among homeless youth may be influenced by characteristics of their social networks. Methods Homeless youth aged 13–24 were randomly sampled from 41 service and street sites in Los Angeles County (N = 419). Predictors of substance use were examined using linear regression analysis (for average number of drinks and average number of cigarettes per day) and negative binomal regression analysis (for frequency of past month marijuana use). Results Youth with more substance users in their networks reported greater alcohol, cigarette, and marijuana consumption regardless of whether these network members provided tangible or emotional support. Marijuana use was more frequent for youth who met more network members through homeless settings, but less frequent among those who met more network members through treatment or AA/NA. Greater alcohol use occurred among youth who met more network members through substance use-related activities. Youth having more adults in positions of responsibility in their networks consumed less alcohol, and those with more school attendees in their networks consumed less alcohol and cigarettes. Conclusions Findings highlight the importance of social context in understanding substance use among homeless youth. Results also support the relevance of network-based interventions to change social context for substance using youth, in terms of both enhancing pro-social influences and reducing exposure to substance use.

Objective Adolescents with Attention Deficit/Hyperactivity Disorder (ADHD) are at an increased risk for substance use but the pathways through which this risk emerges are insufficiently understood. Method Tobacco, alcohol, and marijuana outcomes were compared between adolescents diagnosed with ADHD in early childhood (N=113) and demographically similar controls (N=65). Participants were assessed from age 5 until age 18. A comprehensive history of adolescent substance use was compiled for each participant and growth in ADHD and Conduct Disorder (CD) were modeled as they related to substance use outcomes. Results Results indicated that when compared to controls, adolescents with ADHD were more likely to try cigarettes, initiate alcohol use at early ages, and smoke marijuana more frequently. Furthermore, adolescents with ADHD were four to five times more likely than controls to escalate to heavy cigarette and marijuana use after trying these substances once. Adolescents with ADHD who escalated to heavy use patterns were more likely to display early cigarette use and marked problems with family members, but displayed fewer peer problems. There was evidence of baseline effects (latent intercept, measured at age five) for both ADHD and CD on substance use outcomes. Furthermore, growth in ADHD symptoms accounted for much of the growth in CD symptoms, and consequently, escalating CD symptoms in childhood (latent slope) were viewed as a mediator of the relationship between ADHD and cigarette and marijuana use. Maternal drinking in early childhood was the strongest predictor of early adolescent alcohol use. Conclusions These findings are discussed with respect to the role of ADHD in the development of adolescent risk outcomes. PMID:24886010

Unprotected sex has been linked independently to alcohol and marijuana use, but few studies have examined associations with dual use or gender differences in these associations. This study examined day-level associations between unprotected sex, defined as condomless vaginal sex with an opposite-sex partner, and use of alcohol, marijuana, neither, or both substances among 290 young adults (18-25 years, 52.3% female) who reported either alcohol or marijuana use. Participants reported demographics, alcohol use, marijuana use, and at least one episode of condomless sex as defined above in the past 90 days (Timeline Follow-Back). The likelihood of condomless sex was examined for days when alcohol, marijuana, neither, or both were used. Gender differences were also explored. For females, compared to days with no substance use, the estimated risk of condomless sex increased by a factor of 2.12 on alcohol use days, 1.89 on marijuana use days, and 3.39 on dual use days. Among males, the odds of condomless sex increased only slightly on alcohol use (odds ratio [OR] = 1.03) or marijuana use (OR = 1.08) days, but increased by a factor of 1.71 on dual use days. Young persons who use alcohol and/or marijuana experience heightened likelihood of condomless sex. This increased likelihood is greater for women than for men on days with alcohol or marijuana use, each alone but especially when combined. Young women may be especially susceptible to the influence of alcohol and/or marijuana use on sexual behavior. (Am J Addict 2018;XX:1-6). © 2018 American Academy of Addiction Psychiatry.

Background: Whilst several studies have examined inequity of tobacco use and inequity of alcohol drinking individually, comparatively little is known about concurrent tobacco and alcohol consumption. The present study therefore investigated inequity of concurrent tobacco and alcohol consumption in Thailand. Methods: The 2015 Health and Welfare Survey was obtained from Thailand’s National Statistical Office and used as a source of national representative data. Concurrent tobacco and alcohol consumption was defined as current and concurrent use of both tobacco and alcohol. The wealth assets index was used as an indicator of socioeconomic inequity. Socioeconomic status included 5 groups ranging from poorest (Q1) to richest (Q5). A total of 55,920 households and 113,705 participants aged 15 years or over were included and analyzed. A weighted multiple logistic regression was performed. Results: The prevalence of concurrent tobacco and alcohol consumption, tobacco consumption only, and alcohol consumption only were 15.2% (95% CI: 14.9, 15.4), 4.7% (95% CI: 4.5, 4.8), and 18.9% (95% CI: 18.7, 19.1), respectively. Weighted multiple logistic regression showed that concurrent tobacco and alcohol consumption was high in the poorest socioeconomic group (P for trend <0.001), and tobacco consumption only was also high in the poorest group (P for trend <0.001). A high prevalence of alcohol consumption was observed in the richest group (P for trend <0.001). Conclusions: These findings suggest that tobacco and alcohol consumption prevention programs would be more effective if they considered socioeconomic inequities in concurrent tobacco and alcohol consumption rather than focusing on single drug use.

Risky sexual behavior and substance use appear to be interconnected behaviors among adolescents, but data are scarce regarding the extent to which sexual risk behavior is associated with high levels of marijuana and alcohol use, both separately and in combination. 301 adolescents were recruited from a short-term detention facility, and substance use and risky sexual behavior were assessed. We found that adolescents who frequently used marijuana, but not alcohol, reported significantly less risky sex as well as greater intentions to use condoms than either adolescents who frequently used alcohol, but not marijuana, or adolescents who frequently used both substances. Substance use status as a predictor of future risky sexual behavior followed a similar pattern. When designing interventions to reduce substance use in the context of risky sex, it might be especially effective to target efforts toward reducing harm associated with alcohol use, either alone or in combination with marijuana use.

2014-01-01

Using a marijuana vaporizer may have potential harm-reduction advantages on smoking marijuana, in that the user does not inhale smoke. Little research has been published on use of vaporizers. In the first study of individuals using a vaporizer on their own initiative, 96 adults anonymously answered questions about their experiences with a vaporizer and their use of marijuana with tobacco. Users identified 4 advantages to using a vaporizer over smoking marijuana: perceived health benefits, better taste, no smoke smell, and more effect from the same amount of marijuana. Users identified 2 disadvantages: inconvenience of setup and cleaning and the time it takes to get the device operating for each use. Only 2 individuals combined tobacco in the vaporizer mix, whereas 15 combined tobacco with marijuana when they smoked marijuana. Almost all participants intended to continue using a vaporizer. Vaporizers seem to have appeal to marijuana users, who perceive them as having harm-reduction and other benefits. Vaporizers are worthy of experimental research evaluating health-related effects of using them.

This study examined the relative influence of peer socialization and selection on alcohol and marijuana use among 106 adolescents who received a brief intervention. Adolescents were recruited between 2003 and 2007 and followed for 12 months as part of a SAMHSA-funded study. Cross-lagged panel models using four assessment points examined the longitudinal relationship between adolescent substance use and peer substance involvement separately for alcohol and marijuana. Consistent with community studies, there was evidence of both peer socialization and peer selection for alcohol use, and only evidence of peer selection for marijuana use. Implications for research and intervention are discussed. PMID:23965039

Marijuana is seeing increased therapeutic use, and is the world's third most-popular recreational drug following alcohol and tobacco. This widening use poses increased exposure to potentially toxic combustion by-products from marijuana smoke and the potential for public health concerns. To compare urinary metabolites of polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs) among self-reported recent marijuana users and nonusers, while accounting for tobacco smoke exposure. Measurements of PAH and VOC metabolites in urine samples were combined with questionnaire data collected from participants in the National Health and Nutrition Examination Surveys (NHANES) from 2005 to 2012 in order to categorize participants (≥18years) into exclusive recent marijuana users and nonusers. Adjusted geometric means (GMs) of urinary concentrations were computed for these groups using multiple regression analyses to adjust for potential confounders. Adjusted GMs of many individual monohydroxy PAHs (OH-PAHs) were significantly higher in recent marijuana users than in nonusers (p<0.05). Urinary thiocyanate (p<0.001) and urinary concentrations of many VOC metabolites, including metabolites of acrylonitrile (p<0.001) and acrylamide (p<0.001), were significantly higher in recent marijuana users than in nonusers. We found elevated levels of biomarkers for potentially harmful chemicals among self-identified, recent marijuana users compared with nonusers. These findings suggest that further studies are needed to evaluate the potential health risks to humans from the exposure to these agents when smoking marijuana. Published by Elsevier Ltd.

The availability of marijuana products is becoming increasingly prevalent across the United States (US), many states are allowing for the production, processing, and retailing of these products for medical and/or recreational use. The purpose of this study is to: (1) examine the spatial patterning of marijuana licenses, and (2) examine the impact of alcohol outlets in addition to other neighborhood characteristics on marijuana licenses within the state of Washington. This cross-sectional observational study examined 1458 census tracts in Washington state from 2017, using marijuana and alcohol data from the Washington State Liquor and Cannabis Board as well as neighborhood characteristics data from the American Community Survey 2011-2015 5-year estimates. We used exploratory and formal spatial regression methods, including integrated nested Laplace approximation within a Bayesian statistical framework, to address the study aims. Our results indicate there is significant spatial patterning of marijuana producers and processors across the state. We also found that all marijuana licenses are located in poorer census tracts, and marijuana retailers are co-located in census tracts with off-premises alcohol outlets. Our study provides empirical evidence of the relationship between marijuana licenses, alcohol outlets, and neighborhood characteristics, and has important implications for policymakers in other states currently considering legalizing marijuana-products for medical and/or recreational use.

Hicks, Joshua A.; Pedersen, Sarah L.; McCarthy, Denis M.; Friedman, Ronald S.

2009-01-01

Objective: Previous research has shown that primes associated with alcohol influence behavior consistent with specific alcohol expectancies. The present study examined whether exposure to marijuana-related primes and marijuana expectancies interact to produce similar effects. Specifically, the present study examined whether marijuana primes and marijuana expectancies regarding cognitive and behavioral impairment interact to influence performance on an arithmetic task. Method: Two independent samples (N = 260) of undergraduate students (both marijuana users and nonusers) first completed measures of marijuana-outcome expectancies associated with cognitive and behavioral impairment and with general negative effects (Sample 2). Later in the semester, participants were exposed to marijuana-related (or neutral) primes and then completed an arithmetic task. Results: Results from Sample 1 indicated that participants who were exposed to marijuana-themed magazine covers performed more poorly on the arithmetic task if they expected that marijuana would lead to cognitive and behavioral impairment. Results from Sample 2 indicated that, for marijuana users, cognitive and behavioral impairment expectancies, but not expectancies regarding general negative effects, similarly moderated arithmetic performance for participants exposed to marijuana-related words. Conclusions: Results support the hypothesis that the implicit activation of specific marijuana-outcome expectancies can influence cognitive processes. Implications for research on marijuana are discussed. PMID:19371490

Background: Alcohol and tobacco abuse are detrimental to general and oral health. Though the effects of these harmful habits on oral mucosa had been demonstrated, their independent and combined effect on the dental caries experience is unknown and worthy of investigation. Materials and Methods: We compared 268 alcohol-only abusers with 2426 alcohol and tobacco abusers in chewing and smoking forms to test the hypothesis that various components of their dental caries experience are significantly different due to plausible sociobiological explanations. Clinical examination, Decay, Missing, Filled Teeth (DMFT) Index and Oral Hygiene Index - Simplified were measured in a predetermined format. Descriptive statistics, Chi-square test and one-way ANOVA analysis were done using SPSS Version 16.0. Result: The mean DMFT were 3.31, 3.24, 4.09, 2.89 for alcohol-only abusers, alcohol and chewing tobacco abusers, smoking tobacco and alcohol abusers, and those who abused tobacco in smoke and smokeless forms respectively. There was no significant difference between the oral hygiene care measures between the study groups. Presence of attrition among chewers and those with extrinsic stains experienced less caries than others. Discussion and conclusion: The entire study population exhibited a higher incidence of caries experience. Use of tobacco in any form appears to substantially increase the risk for dental caries. Attrition with use of chewing tobacco and presence of extrinsic stains with tobacco use appear to provide a protective effect from caries. The changes in oral micro-flora owing to tobacco use and alcohol may play a critical role in the initiation and progression of dental caries. PMID:21731272

Marijuana use during adolescence is associated with neurocognitive deficits and poorer functioning across several domains. It is likely that more states will pass both medical and recreational marijuana legalization laws in the coming elections; therefore, we must begin to look more closely at the longitudinal effects of medical marijuana (MM) advertising on marijuana use among adolescents so that we can better understand effects that this advertising may have on their subsequent marijuana use and related outcomes. We followed two cohorts of 7th and 8th graders (mean age 13) recruited from school districts in Southern California from 2010 until 2017 (mean age 19) to examine effects of MM advertising on adolescents' marijuana use, cognitions, and consequences over seven years. Latent growth models examined trajectories of self-reported exposure to medical marijuana ads in the past three months and trajectories of use, cognitions, and consequences. Higher average exposure to MM advertising was associated with higher average use, intentions to use, positive expectancies, and negative consequences. Similarly, higher rates of change in MM advertising exposure were associated with higher rates of change in use, intentions, expectancies, and consequences over seven years. Results suggest that exposure to MM advertising may not only play a significant role in shaping attitudes about marijuana, but may also contribute to increased marijuana use and related negative consequences throughout adolescence. This highlights the importance of considering regulations for marijuana advertising, similar to regulations in place for the promotion of tobacco and alcohol in the U.S. Copyright © 2018.

Few studies have examined associations between using alcohol only and using both alcohol and marijuana with sexual behavior on specific occasions. The current study examined alcohol and marijuana use during the most recent sexual experience in association with relationship characteristics, psychological issues, and condom use. Young adult drinkers aged 18-25 who reported not using a condom during sex in the past month were recruited nationally. An analytic subsample (N = 378) was identified based on substance use during the most recent sexual experience [53% female, 70% Caucasian; mean age = 22.42 years (SD = 1.90)]. Using logistic regression, two dummy codes compared the alcohol use only group (n = 197) and the both alcohol and marijuana group (n = 95) to the group who used neither substance (n = 86). Participant sex, drinking frequency, and number of sexual partners were included as covariates. The alcohol only group and the both alcohol and marijuana group had greater odds of being with a casual acquaintance and loss of respect compared to the group who used neither substance. The alcohol only group had greater odds of being with someone they just met and embarrassment compared to the group who used neither substance. No associations were found for condom use or emotional difficulties. Preventative interventions may need to address both alcohol and marijuana to more effectively reduce risky behaviors.

Juvenile detainees comprise a population that engages in high-risk behavior. This study examined sexual risk and substance use behavior and the perceptions of African American female adolescent detainees (N = 765) regarding the influence of alcohol and marijuana use on their social and sexual behaviors. Overall, 58% and 64% reported alcohol and marijuana use, respectively. Alcohol's perceived influence on sexual behavior (p < .001) was significantly different between those who drank and those who did not; marijuana's influence on social (p < .01) and sexual (p < .001) behavior was significantly different between those who used marijuana and those who did not. There is a need for further study of the influence of substance use on social and sexual behavior among African American female adolescent detainees.

The incidence of oropharyngeal and oral tongue cancers has increased over the last 20 years which parallels increased use of marijuana among individuals born after 1950. A pooled analysis was conducted comprising individual-level data from nine case-control studies from the United States and Latin America in the INHANCE consortium. Self-reported information on marijuana smoking, demographic, and behavioral factors was obtained from 1,921 oropharyngeal cases, 356 oral tongue cases, and 7,639 controls. Compared with never marijuana smokers, ever marijuana smokers had an elevated risk of oropharyngeal [adjusted OR (aOR), 1.24; 95% confidence interval (CI): 1.06-1.47] and a reduced risk of oral tongue cancer (aOR, 0.47; 95% CI, 0.29, 0.75). The risk of oropharyngeal cancer remained elevated among never tobacco and alcohol users. The risk of oral tongue cancer was reduced among never users of tobacco and alcohol. Sensitivity analysis adjusting for potential confounding by HPV exposure attenuated the association of marijuana use with oropharyngeal cancer (aOR, 0.99; 95% CI, 0.71-1.25), but had no effect on the oral tongue cancer association. These results suggest that the association of marijuana use with head and neck carcinoma may differ by tumor site. The associations of marijuana use with oropharyngeal and oral tongue cancer are consistent with both possible pro- and anticarcinogenic effects of cannabinoids. Additional work is needed to rule out various sources of bias, including residual confounding by HPV infection and misclassification of marijuana exposure.

With increasing use of state legalized medical marijuana across the country, health care providers need accurate information on patterns of marijuana and other substance use for patients with access to medical marijuana. This study compared frequency and severity of marijuana use, and use of other substances, for patients with and without state legal access to medical marijuana. Data were collected from 2,030 patients who screened positive for marijuana use when seeking health care services in a large, urban safety-net medical center. Patients were screened as part of a federally funded screening, brief intervention, and referral to treatment (SBIRT) initiative. Patients were asked at screening whether they had a state-issued medical marijuana card and about risky use of tobacco, alcohol, and other illicit substances. A total of 17.4% of marijuana users had a medical marijuana card. Patients with cards had higher frequency of marijuana use and were more likely to screen at moderate than low or high risk from marijuana use. Patients with cards also had lower use of other substances than patients without cards. Findings can inform health care providers of both the specific risks of frequent, long-term use and the more limited risks of other substance use faced by legal medical marijuana users.

Do alcohol and marijuana use decrease the probability of condom use for college women?

2014-01-01

Alcohol and marijuana use are thought to increase sexual risk taking, but event-level studies conflict in their findings and often depend on reports from a limited number of people or on a limited number of sexual events per person. With event-level data from 1,856 sexual intercourse events provided by 297 college women (M age = 18 years; 71% White), we used multilevel modeling to examine associations between alcohol and marijuana use and condom use as well as interactions involving sexual partner type and alcohol-sexual risk expectancies. Controlling for alternative contraception use, partner type, regular levels of substance use, impulsivity and sensation seeking, and demographics, women were no more or less likely to use condoms during events involving drinking or heavy episodic drinking than during those without drinking. However, for drinking events, there was a negative association between number of drinks consumed and condom use; in addition, women with stronger alcohol-sexual risk expectancies were marginally less likely to use condoms when drinking. Although there was no main effect of marijuana use on condom use, these data suggest marijuana use with established romantic partners may increase risk of unprotected sex. Intervention efforts should target expectancies and emphasize the dose-response relationship of drinks to condom use.

Epidemiologic review of marijuana use and cancer risk.

Marijuana is the most commonly used illegal drug in the United States and is considered by young adults to be the illicit drug with the least risk. On the other hand, marijuana smoke contains several of the same carcinogens and co-carcinogens as the tar from tobacco, raising concerns that smoking of marijuana may be a risk factor for tobacco-related cancers. We reviewed two cohort studies and 14 case-control studies with assessment of the association of marijuana use and cancer risk. In the cohort studies, increased risks of lung or colorectal cancer due to marijuana smoking were not observed, but increased risks of prostate and cervical cancers among non-tobacco smokers, as well as adult-onset glioma among tobacco and non-tobacco smokers, were observed. The 14 case-control studies included four studies on head and neck cancers, two studies on lung cancer, two studies on non-Hodgkin's lymphoma, one study on anal cancer, one study on penile cancer, and four studies on childhood cancers with assessment of parental exposures. Zhang and colleagues reported that marijuana use may increase risk of head and neck cancers in a hospital-based case-control study in the United States, with dose-response relations for both frequency and duration of use. However, Rosenblatt and co-workers reported no association between oral cancer and marijuana use in a population-based case-control study. An eightfold increase in risk among marijuana users was observed in a lung cancer study in Tunisia. However, there was no assessment of the dose response, and marijuana may have been mixed with tobacco. Parental marijuana use during gestation was associated with increased risks of childhood leukemia, astrocytoma, and rhabdomyosarcoma, but dose-response relations were not assessed. In summary, sufficient studies are not available to adequately evaluate marijuana impact on cancer risk. Several limitations of previous studies include possible underreporting where marijuana use is illegal, small

Background: The Gateway Drug Theory suggests that licit drugs, such as tobacco and alcohol, serve as a "gateway" toward the use of other, illicit drugs. However, there remains some discrepancy regarding which drug--alcohol, tobacco, or even marijuana--serves as the initial "gateway" drug subsequently leading to the use of…

HOW CAN WE USE OUR KNOWLEDGE OF ALCOHOL-TOBACCO INTERACTIONS TO REDUCE ALCOHOL USE?

2013-01-01

Currently, 8.5% of the US population meets criteria for alcohol use disorders, with a total cost to the US economy estimated at $234 billion per year. Alcohol and tobacco use share a high degree of co-morbidity and interact across many levels of analysis. This review begins by highlighting alcohol and tobacco co-morbidity and presenting evidence that tobacco increases the risk for alcohol misuse and likely has a causal role in this relationship. We then discuss how knowledge of alcohol and tobacco interactions can be used to reduce alcohol use focusing on whether; 1) smoking status can be used as a clinical indicator for alcohol misuse; 2) tobacco policies reduce alcohol use; and 3) nAChR medications can be used to treat alcohol use disorders.

Use prevalence of alternative tobacco products and marijuana has increased dramatically. Unfortunately, clinical guidelines have focused on traditional cigarettes with limited attention regarding these emerging public health issues. Thus, it is critical to understand how healthcare professionals view this issue and are responding to it. This qualitative study explored knowledge, beliefs and clinic-based practices regarding traditional and alternative tobacco products (cigar-like products, smokeless tobacco, hookah, e-cigarettes) and marijuana among rural and urban Georgia primary healthcare providers. The sample comprised 20 healthcare providers in primary care settings located in the Atlanta Metropolitan area and rural southern Georgia who participated in semi-structured interviews. Results indicated a lack of knowledge about these products, with some believing that some products were less harmful than traditional cigarettes or that they may be effective in promoting cessation or harm reduction. Few reported explicitly assessing use of these various products in clinic. In addition, healthcare providers reported a need for empirical evidence to inform their clinical practice. Healthcare providers must systematically assess use of the range of tobacco products and marijuana. Evidence-based recommendations or information sources are needed to inform clinical practice and help providers navigate conversations with patients using or inquiring about these products.

Few studies have considered whether the habitual use of tobacco in Southeast Asia is part of an established pattern of addiction that includes regular alcohol use. As part of a national survey of adult tobacco use in Cambodia (n = 13 988), we found that men who smoked were 2 times more likely to have drank alcohol in the past week (odds ratio = 2.53, 95% confidence interval = 2.10–3.03). By age 18 to 25 years, 47% of male smokers drank alcohol, and this pattern of alcohol and tobacco use increased to >55% through the fifth decade. Women using smokeless tobacco with betel quid were more likely to be alcohol drinkers (odds ratio = 1.49, 95% confidence interval = 1.12–1.98). Past week's drinking declined by late middle age and was associated with lower education and being currently married; the behavior was lower in some ethnic groups (ie, Cham). Our findings indicate an important association between alcohol and tobacco use, and raise the possibility that reducing alcohol consumption can be an important component of tobacco control.

A significant proportion of road traffic crashes are attributable to alcohol and marijuana use while driving globally. Sale and use of both substances is illegal in Pakistan and is not considered a threat for road traffic injuries. However literature hints that this may not be the case. We did this study to assess usage of alcohol and marijuana in Pakistani commercial drivers. A sample of 857 commercial bus and truck drivers was interviewed in October 2008 at the largest commercial vehicle station in Rawalpindi and Islamabad, Pakistan. Time location cluster sampling was used to select the subjects and a structured questionnaire was used to assess the basic demographic profile, substance abuse habits of the drivers while on the road, and reasons for usage of illicit substances while driving were recorded. Self reported information was collected after obtaining informed consent. Chi square and fisher exact tests were used to assess differences between groups and logistic regression was used to identify significant associations between driver characteristics and alcohol and marijuana use. Almost 10% of truck drivers use alcohol while driving on Pakistani roads. Marijuana use is almost 30% in some groups. Statistically different patterns of usage are seen between population subgroups based on age, ethnicity, education, and marital status. Regression analysis shows association of alcohol and marijuana use with road rage and error behaviours, and also with an increased risk of being involved in road crashes. The reported reasons for using alcohol or marijuana show a general lack of awareness of the hazardous nature of this practice among the commercial driver population. Alcohol and marijuana use is highly prevalent in Pakistani commercial drivers. The issue needs to be recognized by concerned authorities and methods such as random breath tests and sobriety check points need to be employed for proper law enforcement.

An Item Response Theory Modeling of Alcohol and Marijuana Dependences: A National Drug Abuse Treatment Clinical Trials Network Study*

Wu, Li-Tzy; Pan, Jeng-Jong; Blazer, Dan G.; Tai, Betty; Stitzer, Maxine L.; Brooner, Robert K.; Woody, George E.; Patkar, Ashwin A.; Blaine, Jack D.

2009-01-01

Objective: The aim of this study was to examine psychometric properties of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), diagnostics criteria for alcohol and marijuana dependences among 462 alcohol users and 311 marijuana users enrolled in two multisite trials of the National Drug Abuse Treatment Clinical Trials Network. Method: Diagnostic questions were assessed by the DSM-IV checklist. Data were analyzed by the item response theory and the multiple indicators–multiple causes method procedures. Results: Criterion symptoms of alcohol and marijuana dependences exhibited a high level of internal consistency. All individual symptoms showed good discrimination in distinguishing alcohol or marijuana users between high and low severity levels of the continuum. In both groups, “withdrawal” appeared to measure the most severe symptom of the dependence continuum. There was little evidence of measurement nonequivalence in assessing symptoms of dependence by gender, age, race/ethnicity, and educational level. Conclusions: These findings highlight the clinical utility of the DSM-IV checklist in assessing alcohol- and marijuana-dependence syndromes among treatment-seeking substance users. PMID:19371493

Marijuana initiation during adolescence, and early adolescence in particular, is associated with adverse health consequences. Our study used 2005–2014 data from the annual, cross-sectional National Survey on Drug Use and Health to study the prevalence and correlates of marijuana initiation, use, and marijuana use disorder (MUD; abuse or dependence) among 12- to 14-year olds living in civilian US households (n = 84 954). Examined correlates included age, sex, race/ethnicity, poverty status, metropolitan status, year of survey, depression, tobacco use, alcohol use, and fighting at school. Sex differences in the correlates of lifetime use and past year marijuana initiation were tested via interaction. Lifetime prevalence of marijuana use was 5.5%; 3.2% reported past year initiation. About 1 in 6 (16.8%) past year initiates progressed to MUD within 12 months of first use. Although men had higher prevalence of lifetime use than women, past year initiation did not differ by sex. On examining the sex*race/ethnicity interaction effects, findings determined that non-Hispanic black and Hispanic men had higher prevalence estimates of ever using marijuana and incidence of past year initiation as compared with non-Hispanic white men; these race/ethnicity differences were not found among women. Identifying correlates of initiation and progression to MUD among young adolescents is critical to improve prevention and treatment program targets. PMID:28615948

College attendance is associated with an increased risk for substance use yet we know little about substance use among Native American college students and its regional variation. This study examined alcohol, tobacco, and drug use and their relation to gender, institution, age, and cultural involvement among Native American college students in the Southwest. Native American community college and university students in a large Southwest city (N = 347) completed an online survey about past-month and lifetime substance use and involvement in cultural activities. Cultural involvement was related to less past-month substance use. In the past month, 43% drank alcohol, 27% binge drank, 20% used drugs, and 13% were current smokers. Males, community college students, and older individuals were more likely to have a positive CAGE-AID and have used drugs more than 100 times. Younger individuals were more likely to use marijuana in the past month. These findings highlight cultural strengths and comparatively low rates of tobacco and alcohol use among Native American college students in the Southwest. Copyright © 2018 Elsevier Ltd.

Goldstein, A O; Sobel, R A; Newman, G R

Tobacco and alcohol use among youth are major public health problems, but the extent to which children are routinely exposed to tobacco and alcohol products in children's films is unknown. To identify the prevalence and characteristics associated with tobacco and alcohol use portrayed in G-rated, animated feature films. Design All G-rated, animated feature films released between 1937 and 1997 by 5 major production companies (Walt Disney Co, MGM/United Artists, Warner Brothers Studios, Universal Studios, and 20th Century Fox) that were available on videotape were reviewed for episodes of tobacco and alcohol use. Presence of tobacco and alcohol use in each film, type of tobacco or alcohol used, duration of use, type of character using substance (bad, neutral, or good), and any associated effects. Of 50 films reviewed, 34 (68%) displayed at least 1 episode of tobacco or alcohol use. Twenty-eight (56%) portrayed 1 or more incidences of tobacco use, including all 7 films released in 1996 and 1997. Twenty-five films (50%) included alcohol use. Smoking was portrayed on screen by 76 characters for more than 45 minutes in duration; alcohol use was portrayed by 63 characters for 27 minutes. Good characters use tobacco and alcohol as frequently as bad characters. Cigars and wine are shown in these films more often than other tobacco or alcohol substances. More than two thirds of animated children's films feature tobacco or alcohol use in story plots without clear verbal messages of any negative long-term health effects associated with use of either substance.

Marijuana Use and Achievement of Abstinence from Alcohol and Other Drugs among People with Substance Dependence: A Prospective Cohort Study

2014-01-01

Background Many with alcohol and other drug dependence have concurrent marijuana use, yet it is not clear how to address it during addiction treatment. This is partially due to the lack of clarity about whether marijuana use impacts one’s ability to achieve abstinence from the target of addiction treatment. We examined the association between marijuana use and abstinence from other substances among individuals with substance dependence. Methods A secondary analysis of the Addiction Health Evaluation And Disease management study, a randomized trial testing the effectiveness of chronic disease management. Individuals met criteria for drug or alcohol dependence and reported recent drug (i.e. opioid or stimulant) or heavy alcohol use. Recruitment occurred at an inpatient detoxification unit, and all participants were referred to primary medical care. The association between marijuana use and later abstinence from drug and heavy alcohol use was assessed using longitudinal multivariable models. Results Of 563 study participants, 98% completed at least one follow-up assessment and 535 (95%) had at least one pair of consecutive assessments and were included. In adjusted analyses, marijuana use was associated with a 27% reduction in the odds of abstinence from drug and heavy alcohol use (adjusted odds ratio 0.73 [95% CI, 0.56–0.97], P=0.03). Conclusions Marijuana use among individuals with alcohol or other drug dependence is associated with a lower odds of achieving abstinence from drug and heavy alcohol use. These findings add evidence that suggests concomitant marijuana use among patients with addiction to other drugs merits attention from clinicians. PMID:24986785

Alliance between tobacco and alcohol industries to shape public policy

Jiang, Nan

2013-01-01

Aims The tobacco and alcohol industries share common policy goals when facing regulation, opposing policies such as tax increases and advertising restrictions. The collaboration between these two industries in the tobacco policy arena is unknown. This study explored if tobacco and alcohol companies built alliances to influence tobacco legislation, and if so, how those alliances worked. Methods Analysis of previously secret tobacco industry documents. Findings In the early 1980s, tobacco companies started efforts to build coalitions with alcohol and other industries to oppose cigarette excise taxes, clean indoor air policies, and tobacco advertising and promotion constraints. Alcohol companies were often identified as a key partner and source of financial support for the coalitions. These coalitions had variable success interfering with tobacco control policymaking. Conclusions The combined resources of tobacco and alcohol companies may have affected tobacco control legislation. These alliances helped to create the perception that there is a broader base of opposition to tobacco control. Advocates should be aware of the covert alliances between tobacco, alcohol, and other industries and expose them to correct this misperception. PMID:23587076

2016-01-01

Marijuana, behind only tobacco and alcohol, is the most popular recreational drug in America with prevalence rates of use rising over the past decade. A wide range of research has highlighted neurocognitive deficits associated with marijuana use, particularly when initiated during childhood or adolescence. Neuroimaging, describing alterations to brain structure and function, has begun to provide a picture of possible mechanisms associated with the deleterious effects of marijuana use. This chapter provides a neurodevelopmental framework from which recent data on brain structural and functional abnormalities associated with marijuana use is reviewed. Based on the current data, we provide aims for future studies to more clearly delineate the effects of marijuana on the developing brain and to define underlying mechanisms of the potential long-term negative consequences of marijuana use.

Use prevalence of alternative tobacco products and marijuana has increased dramatically. Unfortunately, clinical guidelines have focused on traditional cigarettes with limited attention regarding these emerging public health issues. Thus, it is critical to understand how healthcare professionals view this issue and are responding to it. This qualitative study explored knowledge, beliefs and clinic-based practices regarding traditional and alternative tobacco products (cigar-like products, smokeless tobacco, hookah, e-cigarettes) and marijuana among rural and urban Georgia primary healthcare providers. The sample comprised 20 healthcare providers in primary care settings located in the Atlanta Metropolitan area and rural southern Georgia who participated in semi-structured interviews. Results indicated a lack of knowledge about these products, with some believing that some products were less harmful than traditional cigarettes or that they may be effective in promoting cessation or harm reduction. Few reported explicitly assessing use of these various products in clinic. In addition, healthcare providers reported a need for empirical evidence to inform their clinical practice. Healthcare providers must systematically assess use of the range of tobacco products and marijuana. Evidence-based recommendations or information sources are needed to inform clinical practice and help providers navigate conversations with patients using or inquiring about these products. © The Author 2016.

Youth with a history of child maltreatment use substances and develop substance use disorders at rates above national averages. Thus far, no research has examined pathways from maltreatment to age of substance use initiation for maltreated youth. We examined the longitudinal impact of maltreatment in early childhood on age of alcohol and marijuana use initiation, and whether internalizing and externalizing behaviors at age 8 mediates the link between maltreatment and age of substance use initiation. Data were drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) at ages 4, 8, 12, and 18. Maltreatment was assessed through reviews of administrative records and youth self-reports. Behavior problems were assessed with the Child Behavior Checklist. Age of substance use initiation was assessed with the Young Adult version of the Diagnostic Interview Schedule for Children. Path analyses indicated mediated effects from a history of maltreatment to age at first alcohol and marijuana use through externalizing behaviors. Considering type of maltreatment, direct effects were found from physical abuse to age of alcohol initiation, and mediated effects were found from sexual abuse and neglect to initial age of alcohol and marijuana use through externalizing behaviors. Direct effects for marijuana use initiation and indirect effects through internalizing behavior problems were not significant for either substance. Externalizing behavior is one pathway from childhood maltreatment to age of substance use initiation. Services for maltreated youth should incorporate substance use prevention, particularly among those with early externalizing problems. Copyright © 2017 Elsevier Ltd. All rights reserved.

2012-01-01

Prevalence data indicate that alcohol and marijuana are frequently used intoxicants among young adults in the United States. In a number of studies, both alcohol use and marijuana use have been associated with failure to use condoms, a high risk sexual behavior. The purpose of the current study was to assess the individual and additive effects of alcohol and marijuana use on this risky sexual behavior among 251, young adult, female, bar drinkers. Multi-level modeling was used to assess the likelihood of condom use during sexual events that occurred as a function of substance use (none, only alcohol, only marijuana, or both) prior to and partner type during the event, as well as individual differences in sexual assertiveness. Initial model testing (level 1 and 2) revealed that there were significant main effects for partner type (known), substance use (alcohol and marijuana) and sexual assertiveness (refusal, pregnancy/STI prevention) on risky sex. Final model testing indicated that sexual assertiveness interacted with substance use to influence risky sex. Women who were low in sexual assertiveness refusal were more likely to engage in risky sex on days when they had consumed both alcohol and marijuana prior to the sexual activity. These findings highlight the complex nature of the relationship between substance use and risky sex. PMID:22612253

Daily affect and substance use covary among college students, but little is known about these associations among young adults not in college. The current pilot study examines associations between positive and negative affect and alcohol and marijuana use, with a focus on differences between college student and nonstudent young adults. High school seniors completed a baseline survey during the spring of 2012 and were then randomly selected to participate in an intensive measurement follow-up. Participants in the follow-up (N = 72, 40.3% men, 77.8% White, 66.7% full-time college students) completed up to 14 consecutive web-based daily surveys during the fall after high school completion. Multilevel models in which days (Level 1) were nested in persons (Level 2) were estimated. Weekend days were associated with increased alcohol use among all young adults, increased marijuana use among college students, and decreased marijuana use among nonstudents. For young adults not in college, greater daily positive affect was associated with increased likelihood of binge drinking, consuming a greater number of drinks, and lower odds of marijuana use; greater daily negative affect was associated with lower odds of alcohol use and lower odds of binge drinking for non-students. For college students, greater daily negative affect was associated with lower odds of marijuana use. Daily affect and alcohol and marijuana use covary among young adults, though these associations differ between students and non-students. Results highlight the need to examine predictors of alcohol and marijuana use among young adults who do not attend college.

2008-01-01

Alcohol and marijuana use are prevalent in adolescence, yet the neural impact of concomitant use remains unclear. We previously demonstrated functional magnetic resonance imaging (fMRI) response to spatial working memory (SWM) among teens with alcohol use disorders (AUD) compared to controls, and predicted that adolescents with marijuana and alcohol use disorders would show additional abnormalities. Participants were three groups of 15−17-year-olds: 19 non-abusing controls, 15 AUD teens with limited exposure to drugs, and 15 teens with comorbid marijuana and alcohol use disorders (MAUD) and minimal other drug experience. After >2 days’ abstinence, participants performed a SWM task during fMRI acquisition. fMRI brain response patterns differed between groups, despite similar performance on the task. MAUD youths showed less activation in inferior frontal and temporal regions than controls, and more response in other prefrontal regions. Compared to AUD teens, MAUD youths also showed less inferior frontal and temporal activation, but more medial frontal response. Overall, MAUD youths showed different brain response abnormalities than teens with AUD alone, despite relatively short histories of substance involvement. This pattern could suggest compensation for marijuana-related attention and working memory deficits. However, relatively recent use and premorbid features may influence results, and should be examined in future studies. PMID:16002029

Fox, Helen C.; Tuit, Keri L.; Sinha, Rajita

2013-01-01

Objective To date, little research exists defining bio-behavioral adaptations associated with both marijuana abuse and risk of craving and relapse to other drugs of abuse during early abstinence. Method Fifty-nine treatment-seeking individuals dependent on alcohol and cocaine were recruited. Thirty of these individuals were also marijuana (MJ) dependent; 29 were not. Twenty-six socially drinking healthy controls were also recruited. All participants were exposed to three 5-min guided imagery conditions (stress, alcohol/cocaine cue and relaxing), presented randomly, one per day across three consecutive days. Measures of craving, anxiety, heart rate, blood pressure, plasma adrenocorticotrophic hormone and cortisol were collected at baseline and subsequent recovery time points. Results The MJ-dependent group showed increased basal anxiety ratings and cardiovascular output alongside enhanced alcohol craving and cocaine craving, and dampened cardiovascular response to stress and cue. They also demonstrated elevated cue-induced anxiety and stress-induced cortisol and adrenocorticotrophic hormone levels, which were not observed in the non-MJ-dependent group or controls. Cue-related alcohol craving and anxiety were both predictive of a shorter number of days to marijuana relapse following discharge from inpatient treatment. Conclusions Findings provide some support for drug cross-sensitization in terms of motivational processes associated with stress-related and cue-related craving and relapse. PMID:23280514

Urban-Rural Differentials: A Spatial Analysis of Alabama Students’ Recent Alcohol Use and Marijuana Use

Lo, Celia C.; Weber, Joe; Cheng, Tyrone C.

2013-01-01

Background and Objectives This study of Alabama public school students sought urban-rural differences in social and spatial mechanisms connecting structural factors to recent use of alcohol and marijuana. Methods Its dataset comprised a state-sponsored 2002 need-assessment survey of Alabama students; Alabama education department data; U. S. Census data; and alcohol-outlet locations listed by Alabama’s Alcoholic Beverage Control Board. It measured structural-disadvantage factors (population disadvantages, community instability, alcohol-outlet density), social-organization factors (protective role of community, protective role of school), and recent-use factors. Using Geographic Information Systems (GIS), it generated maps of school catchment areas (SCAs)—the units of analysis for the study—that outline spatial patterns (across areas deemed urban or rural) of students’ recent use of alcohol and marijuana. Results In the final sample of 370 SCAs, significant urban-versus-rural differences were observed for certain structural factors and in how these factors were associated with substance use. These differences aside, spatial analysis weighing the SCAs’ particular geographic characteristics suggested location’s importance, showing that a school playing a strong protective role significantly reduced not just its own students’ recent substance use, but that of students in neighboring SCAs as well. Conclusions and Scientific Significance The findings show students’ recent use of alcohol and marijuana are associated with characteristics of the environment. PMID:23617858

Smoked marijuana as a cause of lung injury.

PubMed

Tashkin, D P

2005-06-01

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.

to analyze the effect of self-esteem, assertiveness, self-efficacy and resiliency on alcohol and tobacco consumption in adolescents. a descriptive and correlational study was undertaken with 575 adolescents in 2010. The Self-Esteem Scale, the Situational Confidence Scale, the Assertiveness Questionnaire and the Resiliency Scale were used. the adjustment of the logistic regression model, considering age, sex, self-esteem, assertiveness, self-efficacy and resiliency, demonstrates significance in the consumption of alcohol and tobacco. Age, resiliency and assertiveness predict alcohol consumption in the lifetime and assertiveness predicts alcohol consumption in the last year. Similarly, age and sex predict tobacco consumption in the lifetime and age in the last year. this study can offer important information to plan nursing interventions involving adolescent alcohol and tobacco users.

To examine the event-specific relationship between alcohol intoxication and nighttime tobacco smoking among college bar patrons. In this secondary analysis of existing data, we examined event-specific associations between self-report measures of tobacco smoking and breath alcohol concentration (BrAC) readings obtained from 424 patrons exiting on-premise drinking establishments. In a multivariable logistic regression analysis, acute alcohol intoxication was positively associated with same-night incidents of smoking tobacco, adjusting for the effects of established smoking practices and other potential confounders. This investigation is the first known study using data collected in an on-premise drinking setting to link alcohol intoxication to specific incidents of tobacco smoking.

2014-11-01

To describe the social, clinical and use-patterns characteristics of medicinal marijuana use among patients with epilepsy (PWEs). Eighteen PWEs with prescriptions for medicinal marijuana from a Canadian adult-epilepsy clinic were included in this study. Eighteen patients had a prescription of medicinal marijuana from a total population of 800 PWEs in our center (2.2%). Mean age of patients was 30±7.4 (19-50) years. Twelve (67%) patients were males. Eleven (61%) patients had drug-resistant epilepsy. Eleven (61%) patients suffered a psychiatric comorbidity and reported the use of illicit substances or heavy alcohol or tobacco consumption. Only two (11%) patients were married; the rest of patients (89%) were single or divorced. The drug use pattern was similar among patients. All patients asked for marijuana permission in the epilepsy clinic. Most (83%) had a previous history of marijuana smoking, with a mean of 6.6±3 (1-15) years. The mean consumption dose was 2.05±1.8 (0.5-8) grams per day. Ten (56%) patients reported withdrawal seizure exacerbation when they stopped the marijuana. Only two patients (11%) reported side effects, and all patients found medicinal marijuana very helpful for seizure control and improvement of mood disorder. PWEs using medicinal marijuana have a common profile. They are usually young single men with drug-resistant epilepsy and psychiatric comorbidity.

Because of the concurrent use of other antiseizure medications, it is complex to estimate the actual effect of marijuana.

While alcohol remains the drug of choice among college students, marijuana ranks number two with 32 percent reporting using marijuana in 2008. That's a modest decline from 2001, when 36 percent of college students reported marijuana use. While levels of marijuana use by students are determined through a number of national and local surveys, no…

OBJECTIVES: to analyze the effect of self-esteem, assertiveness, self-efficacy and resiliency on alcohol and tobacco consumption in adolescents. METHOD: a descriptive and correlational study was undertaken with 575 adolescents in 2010. The Self-Esteem Scale, the Situational Confidence Scale, the Assertiveness Questionnaire and the Resiliency Scale were used. RESULTS: the adjustment of the logistic regression model, considering age, sex, self-esteem, assertiveness, self-efficacy and resiliency, demonstrates significance in the consumption of alcohol and tobacco. Age, resiliency and assertiveness predict alcohol consumption in the lifetime and assertiveness predicts alcohol consumption in the last year. Similarly, age and sex predict tobacco consumption in the lifetime and age in the last year. CONCLUSION: this study can offer important information to plan nursing interventions involving adolescent alcohol and tobacco users. PMID:25591103

Alcohol use disorders and tobacco use contribute significant risk to the global burden of disease, and each are major public health concerns. Together, alcohol and tobacco use are highly comorbid and have multiplicative health risks when used concurrently, underscoring the importance of examining alcohol-tobacco interactions in the human laboratory. The aims of this review were to summarize the state of research examining alcohol-tobacco interactions in the human laboratory. We reviewed human laboratory evidence for alcohol and tobacco/nicotine interactions, including 1) craving in drinkers and smokers exposed to smoking or drinking cues, 2) fixed-dosing of alcohol or nicotine in smokers and drinkers, and 3) smoking and alcohol influences on self-administration behaviors. The interactive effects of tobacco/nicotine with other drugs of abuse are also briefly discussed. Overall, results identified that alcohol and tobacco have reciprocal influences on potentiating craving, subjective responses to fixed-dose alcohol or nicotine administration, and self-administration. The literature identified that alcohol increases craving to smoke, decreases time to initiate smoking, and increases smoking self-administration. Similarly, tobacco and nicotine increase alcohol craving, decrease subjective effects of alcohol, and increase alcohol consumption. Future studies should continue to focus on alcohol and tobacco/nicotine interactions in individuals with a wide scope of drinking and smoking histories, different states of alcohol and nicotine deprivation, and influences of either drug on craving, subjective responses, and consumption over the course of the blood alcohol curve. This work could have important implications for the impact of alcohol-tobacco interactions on guiding clinical practice, as well as in the changing landscape of addiction.

Historically, the alcohol and tobacco industries have been the biggest users of outdoor advertising. However, the 1999 Master Settlement Agreement (MSA) outlawed tobacco billboards and transit furniture (e.g., bus, bench) ads, and the Outdoor Advertising Association of America (OAAA) has pledged to voluntarily eliminate ads for alcohol and tobacco within 500 feet of schools, playgrounds, and churches. Outdoor advertisements were observed (2004-2005) in a sample of urban census tracts (106 in pre-Katrina southern Louisiana and 114 in Los Angeles County) to evaluate tobacco and alcohol advertisers' compliance with the MSA and the OAAA Code of Industry Principles. Data were analyzed in 2007-2008. More than one in four tobacco ads in Louisiana failed to comply with the MSA. In Los Angeles, 37% of alcohol ads and 25% of tobacco ads were located within 500 feet of a school, playground, or church; in Louisiana, roughly one in five ads promoting alcohol or tobacco fell within this distance. In Los Angeles, low-income status and the presence of a freeway in the tract were associated with 40% more alcohol and tobacco billboards near children. In Louisiana, each additional major roadway-mile was associated with 4% more tobacco ads-in violation of MSA-and 7% more small ads near schools, playgrounds, and churches; city jurisdiction accounted for 55% of MSA violations and more than 70% of the violations of OAAA guidelines. Cities must be empowered to deal locally with violations of the MSA. Legislation may be needed to force advertisers to honor their pledge to protect children from alcohol and tobacco ads.

Marijuana and Alcohol Use as Predictors of Academic Achievement: A Longitudinal Analysis Among Youth in the COMPASS Study.

2017-05-01

We tested the effect of initiating marijuana and alcohol use at varying frequencies on academic indices. In a sample of 26,475 grade 9-12 students with at least 2 years of linked longitudinal data from year 1 (Y1: 2012-2013), year 2 (Y2: 2013-2014), and year 3 (Y3: 2014-2015) of the COMPASS study, separate multinomial generalized estimating equations models tested the likelihood of responses to measures of academic goals, engagement, preparedness, and performance when shifting from never using alcohol or marijuana at baseline to using them at varying frequencies at follow -up. Students who began using alcohol or marijuana were less likely to attend class regularly, complete their homework, achieve high marks, and value good grades, relative to their abstaining peers. Changing from abstaining to rare/sporadic-to-weekly drinking or rare/sporadic marijuana use predicted aspirations to continue to all levels of higher education, and initiating weekly marijuana use increased the likelihood of college ambitions, while more regular marijuana use reduced the likelihood of wanting to pursue graduate/professional degrees, over high school. The importance of delaying or preventing substance use is evident in associations with student performance and engagement. The influence on academic goals varied by substance and frequency of initiated use. © 2017, American School Health Association.

Marijuana and Lung Disease.

PubMed

Tashkin, Donald P

2018-05-17

As marijuana smoking prevalence increases in the U.S. concern regarding its potential risks to lung health has also risen, given the general similarity in the smoke contents between marijuana and tobacco. Most studies have found a significant association between marijuana smoking and chronic bronchitis symptoms after adjustment for tobacco. While reports are mixed regarding associations between marijuana smoking and lung function, none has shown a relationship to decrements in forced expired volume in 1 sec (FEV1) and few have found a relationship to a decreased ratio of FEV1 to forced vital capacity (FVC), possibly related to an association between marijuana and an increased FVC. A few studies have found a modest reduction in specific airway conductance in relation to marijuana, probably reflecting endoscopic evidence of bronchial mucosal edema among habitual marijuana smokers. Diffusing capacity in marijuana smokers has been normal and two studies of thoracic high-resolution computed tomography (HRCT) have not shown any association of marijuana smoking with emphysema. Although bronchial biopsies from habitual marijuana smokers have shown precancerous histopathological changes, a large cohort study and a pooled analysis of six well-designed case-control studies have not found evidence of a link between marijuana smoking and lung cancer. The immunosuppressive effects of delta-9 tetrahydrocannabinol raise the possibility of an increased risk of pneumonia, but further studies are needed to evaluate this potential risk. Several cases series have demonstrated pneumothoraces/pneumomediastinum, as well as bullous lung disease, in marijuana smokers, but these associations require epidemiologic studies for firmer evidence of possible causality.

2017-09-01

There is concern that changes in marijuana-related policy and public opinion may lead to increased access to marijuana among young people in the United States. However, little research has been conducted on changes in youth's perceptions of marijuana access, and studies have yet to systematically examine trends in perceived access across key sociodemographic and externalizing behavioral subgroups. Using population-based data collected between 2002 and 2015 as part of the National Survey on Drug Use and Health, we examined trends in perceived marijuana access among non-Hispanic White, African American, and Hispanic adolescents (ages 12-17, n = 221,412). Following the trend analysis method outlined by the Centers for Disease Control and Prevention, we conducted logistic regression analyses to test for secular trends. Between 2002 and 2015, we observed a 27% overall reduction in the relative proportion of adolescents ages 12-17-and a 42% reduction among those ages 12-14-reporting that it would be "very easy" to obtain marijuana. This pattern was uniformly observed among youth in all sociodemographic subgroups (i.e., across age, gender, race/ethnicity, household income) and among youth reporting involvement/no involvement in most measures of substance use (alcohol, marijuana) and delinquency (handgun carrying, attacks). However, perceived very easy access remained stable among youth reporting tobacco use and criminal justice system involvement. Despite the legalization of recreational and medical marijuana in some states, our findings suggest that, with the notable exception of adolescent tobacco users and juvenile offenders, perceptions that marijuana would be very easy to obtain are on the decline among American youth.

Given ever-reducing budgets of community and school substance use prevention programs, there is a call for identifying the first substance in the sequence leading to polydrug use. Examining data from a nationally representative sample of 2835 United States 12th graders, we sought to determine (1) the first substance adolescents use; (2) order in which adolescents progress through alcohol, tobacco, and marijuana use; and (3) impact of age of initial substance use on lifetime and frequency of illicit substance use. Alcohol is the most commonly used substance, and the majority of polysubstance using respondents consumed alcohol prior to tobacco or marijuana initiation. Respondents initiating alcohol use in sixth grade reported significantly greater lifetime illicit substance use (M = 1.9, standard deviation [SD] = 1.7, p < .001) and more frequent illicit substance use (M = 6.0, SD = 6.5, p < .001) than those initiating alcohol use in ninth grade or later. Overall, effect sizes for these differences were large (eta squared = 0.30 and 0.28, respectively). Findings underscore the importance of screening for substance use, even among youth enrolled in elementary/middle school. In addition, school prevention programs should begin in elementary school (third grade) and target alcohol use. © 2015, American School Health Association.

Concurrent and Prospective Associations Between Substance-Specific Parenting Practices and Child Cigarette, Alcohol, and Marijuana Use.

2018-06-01

The current study aimed to understand whether substance-specific parenting practices predicted the probability of child alcohol, cigarette, or marijuana use beyond known family factors like family management and parental substance use and norms. Data were drawn from the Intergenerational Project, which used an accelerated longitudinal design and included 383 families surveyed seven times between 2002 and 2011. Analyses included 224 families with children ages 10-18 years (49% female). Multilevel models tested both concurrent and lagged (predictors at time t - 1, outcomes at time t) associations between child past year use of alcohol, cigarettes, and marijuana and time-varying measures of substance-specific parenting practices, including permitting child use of alcohol or cigarettes; family rules about alcohol, cigarette, and drug use; and child involvement in family member alcohol or cigarette use (getting, opening, or pouring alcoholic drinks; getting or lighting cigarettes for family members). Demographic controls were included. Child involvement in family member substance use predicted an increased probability of child substance use both concurrently and 1 year later, even when controlling parent substance use, pro-substance norms, and family management. Family rules about substance use and parent provision of alcohol or cigarettes were not consistently related to child alcohol, cigarette, or marijuana use. Family-based preventive interventions to reduce youth substance use should continue to focus on family management and include messaging discouraging parents from allowing children to get, open, or pour drinks or get or light cigarettes for family members.

Negative affect, stress, and smoking in college students: unique associations independent of alcohol and marijuana use.

Stress and negative affect (NA) figure prominently in theoretical models of smoking initiation, maintenance and relapse, yet few studies have examined these associations among college students. Further complicating examination of these associations, smoking often occurs in the context of other substance use (e.g., alcohol, marijuana) in college populations. Thus, it remains unclear whether stress and NA are associated with cigarette use among college students, and if so, whether these associations are evident after controlling for effects of other substance use. The goals of this study were: a) to examine whether several aspects of stress (objective events, subjective experiences) and NA (sad mood, general emotional distress) were associated with cigarette smoking among college students and b) whether associations remained after accounting for alcohol and marijuana use. A large sample of college freshmen (N=633) followed longitudinally over 35 weeks via internet assessments. Results of hierarchical linear modeling demonstrated that measures of subjective stress and NA were positively related to cigarette use, whereas measures of objective stressful events were negatively related to cigarette use. When alcohol and marijuana use were added to the models, associations between smoking and stress/NA were diminished. Associations between NA and smoking remained significant; however, associations between subjective stress/stressful events and smoking were no longer significant. This is the first study to comprehensively examine links between subjective and objective measures of stress and smoking behavior among college students while also considering the influence of other substance use. Negative affect was the most robust correlate of smoking among college students. Subjective and objective stress do not appear to be strongly associated with college smoking above and beyond alcohol and marijuana use. Stress may not be an important etiological factor for relatively low

Abundant cross-sectional evidence links eveningness (a preference for later sleep-wake timing) and increased alcohol and drug use among adolescents and young adults. However, longitudinal studies are needed to examine whether eveningness is a risk factor for subsequent alcohol and drug use, particularly during adolescence, which is marked by parallel peaks in eveningness and risk for the onset of alcohol use disorders. This study examined whether eveningness and other sleep characteristics were associated with concurrent or subsequent substance involvement in a longitudinal study of adolescents. Participants were 729 adolescents (368 females; age 12 to 21 years) in the National Consortium on Alcohol and Neurodevelopment in Adolescence study. Associations between the sleep variables (circadian preference, sleep quality, daytime sleepiness, sleep timing, and sleep duration) and 3 categorical substance variables (at-risk alcohol use, alcohol bingeing, and past-year marijuana use [y/n]) were examined using ordinal and logistic regression with baseline age, sex, race, ethnicity, socioeconomic status, and psychiatric problems as covariates. At baseline, greater eveningness was associated with greater at-risk alcohol use, greater bingeing, and past-year use of marijuana. Later weekday and weekend bedtimes, but not weekday or weekend sleep duration, showed similar associations across the 3 substance outcomes at baseline. Greater baseline eveningness was also prospectively associated with greater bingeing and past-year use of marijuana at the 1-year follow-up, after covarying for baseline bingeing and marijuana use. Later baseline weekday and weekend bedtimes, and shorter baseline weekday sleep duration, were similarly associated with greater bingeing and past-year use of marijuana at the 1-year follow-up after covarying for baseline values. Findings suggest that eveningness and sleep timing may be under recognized risk factors and future areas of intervention for

Tobacco smoking, alcohol consumption and gastro-oesophageal reflux disease.

PubMed

Ness-Jensen, Eivind; Lagergren, Jesper

2017-10-01

Gastro-oesophageal reflux disease (GORD) develops when reflux of gastric content causes troublesome symptoms or complications. The main symptoms are heartburn and acid regurgitation and complications include oesophagitis, strictures, Barrett's oesophagus and oesophageal adenocarcinoma. In addition to hereditary influence, GORD is associated with lifestyle factors, mainly obesity. Tobacco smoking is regarded as an aetiological factor of GORD, while alcohol consumption is considered a triggering factor of reflux episodes and not a causal factor. Yet, both tobacco smoking and alcohol consumption can reduce the lower oesophageal sphincter pressure, facilitating reflux. In addition, tobacco smoking reduces the production of saliva rich in bicarbonate, which is important for buffering and clearance of acid in the oesophagus. Alcohol also has a direct noxious effect on the oesophageal mucosa, which predisposes to acidic injury. Tobacco smoking cessation reduces the risk of GORD symptoms and avoidance of alcohol is encouraged in individuals where alcohol consumption triggers reflux. Copyright © 2017 Elsevier Ltd.

Whilst schools provide a potentially appropriate setting for preventing substance use among young people, systematic review evidence suggests that past interventions in this setting have demonstrated limited effectiveness in preventing tobacco, alcohol and other drug use. Interventions that adopt a mental wellbeing approach to prevent substance use offer considerable promise and resilience theory provides one method to impact on adolescent mental well-being. The aim of the proposed study is to examine the efficacy of a resilience intervention in decreasing the tobacco, alcohol and illicit drug use of adolescents. A cluster randomised controlled trial with schools as the unit of randomisation will be undertaken. Thirty two schools in disadvantaged areas will be allocated to either an intervention or a control group. A comprehensive resilience intervention will be implemented, inclusive of explicit program adoption strategies. Baseline surveys will be conducted with students in Grade 7 in both groups and again three years later when the student cohort is in Grade 10. The primary outcome measures will include self-reported tobacco, alcohol, marijuana and other illicit drug use. Comparisons will be made post-test between Grade 10 students in intervention and control schools to determine intervention effectiveness across all measures. To the authors' knowledge this is the first randomised controlled trial to evaluate the effectiveness of a comprehensive school-based resilience intervention, inclusive of explicit adoption strategies, in decreasing tobacco, alcohol and illicit drug use of adolescents attending disadvantaged secondary schools.

The harm from alcohol and tobacco use in low- and middle-income countries includes substantial economic cost to the individual. Our aim was to describe the expenditure on concurrent alcohol and tobacco use in relation to family income in two districts in Sri Lanka. A community-based cross-sectional study was carried out in two districts in Sri Lanka. We sampled 2684 men over 18 years of age using multistage cluster sampling. Cost of alcohol and cigarettes was calculated using the retail price for each brand and multiplying by the amount consumed. Among current alcohol users 63.1% were also smokers. Among current smokers 61.9% were also using alcohol. Prevalence of concurrent alcohol and tobacco use in urban areas was 20.1% and in rural areas 14%. The two lowest income categories (<$US76 per month) spent more than 40% of their income on concurrent use while the next category ($US76-143 per month) spent 34.8% of their income on concurrent use. The poor spent less than those with higher income on alcohol and tobacco, but the expenditure constituted a much larger slice of their income thus compromising their ability to meet basic needs. In low-income countries, damaging economic consequences start at lower levels of alcohol and tobacco consumption and affect a significant proportion of the population. Defining risk levels and guidelines on safe limits based purely on individual health harm has, at best, little meaning in such settings. © 2010 Australasian Professional Society on Alcohol and other Drugs.

The use of social networking sites: A risk factor for using alcohol, marijuana, and synthetic cannabinoids?

The use of social networking sites (SNS) has become a central aspect of youth culture allowing individuals to explore and assert their identities. A commonly portrayed online identity is an "alcohol identity," and past research suggests such identities may contribute to one's risk of using alcohol. The present study builds on past research by examining the relationship between alcohol, marijuana, and synthetic cannabinoid use (e.g., Spice, K2) and time spent on SNS in a sample of college students. Six hundred ninety nine undergraduates (62.4% female; Mage=21.0, SD=8.56) were recruited from a university on the U.S./Mexico border for an online study. Participants completed measures assessing demographics, substance use history, and amount of time spent on SNS. Participants reported spending 46h per month on SNS. Seventy-one percent, 14%, and 3% of the sample reported past month use of alcohol, marijuana, and synthetic cannabinoids, respectively. Regression analyses revealed that hours spent on SNS in the past month were significantly associated with frequency of alcohol (p<0.001) and synthetic cannabinoid use (p<0.001). In addition, being male was associated with frequency of alcohol and marijuana use in the past month (p<0.001 and p<0.001, respectively). These findings suggest that assessment of time spent on SNS is warranted in studies investigating drug use among college students. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Implications of marijuana legalization for adolescent substance use.

PubMed

Hopfer, Christian

2014-01-01

Marijuana that is legally available for adults has multiple implications for adolescent substance use. One potential effect that legalization may have is an increase in adolescent use to due increased availability, greater social acceptance, and possibly lower prices. Legalization may also facilitate the introduction of new formulations of marijuana (edible, vaporized) and with potentially higher potencies. It is unknown what adolescent consumption patterns will be if marijuana is widely available and marketed in different forms, or what effects different patterns of adolescent use will have on cognition, the development of marijuana use disorders, school performance, and the development of psychotic illnesses. Also unclear is whether adolescent users will be experiencing higher levels of tetrahydrocannabinol (THC) compared with previous generations of users due to higher potencies. Although previous studies of the effects of adolescent marijuana use provide some guidance for current policy and public health recommendations, many new studies will be needed that answer questions in the context of use within a legal adult environment. Claims that marijuana has medicinal benefits create additional challenges for adolescent prevention efforts, as they contrast with messages of its harmfulness. Prevention and treatment approaches will need to address perceptions of the safety of marijuana, claims of its medicinal use, and consider family-wide effects as older siblings and parents may increasingly openly consume and advocate for marijuana use. Guidance for primary care physicians will be needed regarded screening and counseling. Widespread legalization and acceptance of marijuana implies that as law enforcement approaches for marijuana control decline, public health, medical, and scientific efforts to understand and reduce negative consequences of adolescent marijuana use need to be substantially increased to levels commensurate with those efforts for tobacco and alcohol.

The effect of adolescent marijuana use on brain development remains unclear despite relaxing legal restrictions, decreased perceived harm, and increasing use rates among youth. The aim of this 3-year prospective study was to evaluate the long-term neurocognitive effects of adolescent marijuana use. Adolescent marijuana users with concomitant alcohol use (MJ + ALC, n = 49) and control teens with limited substance use histories (CON, n = 59) were given neuropsychological and substance use assessments at project baseline, when they were ages 16-19. They were then reassessed 18 and 36 months later. Changes in neuropsychological measures were evaluated with repeated measures analysis of covariance (ANCOVA), controlling for lifetime alcohol use, and examined the effects of group, time, and group by time interactions on cognitive functioning. MJ + ALC users performed significantly worse than controls, across time points, in the domains of complex attention, memory, processing speed, and visuospatial functioning (ps <.05). Earlier age of marijuana use onset was associated with poorer processing speed and executive functioning by the 3-year follow-up (ps ≤.02). Frequent marijuana use throughout adolescence and into young adulthood appeared linked to worsened cognitive performance. Earlier age of onset appears to be associated with poorer neurocognitive outcomes that emerge by young adulthood, providing further support for the notion that the brain may be uniquely sensitive to frequent marijuana exposure during the adolescent phase of neurodevelopment. Continued follow-up of adolescent marijuana users will determine the extent of neural recovery that may occur if use abates. (c) 2015 APA, all rights reserved).

Initiation of tobacco, alcohol and illicit substance use typically occurs during adolescence, with the school setting recommended to reduce adolescent substance use. Strengthening individual (eg, problem solving) and environmental (eg, caring relationships at school) resilience protective factors of adolescents has been suggested as a strategy for reducing substance use by adolescents; however, few studies have examined this potential. A study was conducted to investigate the effectiveness of a pragmatic school-based universal 'resilience' intervention in reducing the prevalence of tobacco, alcohol and illicit substance use, and increasing the individual and environmental protective factors of students. A cluster-randomised controlled trial. Thirty-two Australian secondary schools (20 intervention; 12 control). Cohort of grade 7 students followed-up in grade 10 (2014; aged 15-16 years). A pragmatic intervention involving school staff selection and implementation of available programmes and resources targeting individual and environmental 'resilience' protective factors for all grade 7-10 students was implemented in schools (2012-2014). School staff were provided implementation support. An online survey collected baseline and follow-up data for primary outcomes: tobacco (ever, recent) and alcohol (ever, recent, 'risk') use, and secondary outcomes: marijuana and other illicit substance use, and individual (six-factor subscales, aggregate) and environmental (three-factor subscales, aggregate) protective factor scores. Generalised and linear mixed models examined follow-up differences between groups. Follow-up data from 2105 students (intervention=1261; control=844; 69% of baseline cohort) were analysed. No significant differences were found between intervention and control students for any primary (ever tobacco: OR 1.25, 95% CI 0.92 to 1.68, p=0.14; recent tobacco: OR 1.39, 95% CI 0.84 to 2.31, p=0.19; recent ever alcohol: OR 1.11, 95% CI 0.83 to 1.48, p=0

Intervention A pragmatic intervention involving school staff selection and implementation of available programmes and resources targeting individual and environmental ‘resilience’ protective factors for all grade 7–10 students was implemented in schools (2012–2014). School staff were provided implementation support. Measurements An online survey collected baseline and follow-up data for primary outcomes: tobacco (ever, recent) and alcohol (ever, recent, ‘risk’) use, and secondary outcomes: marijuana and other illicit substance use, and individual (six-factor subscales, aggregate) and environmental (three-factor subscales, aggregate) protective factor scores. Generalised and linear mixed models examined follow-up differences between groups. Results Follow-up data from 2105 students (intervention=1261; control=844; 69% of baseline cohort) were analysed. No significant differences were found between intervention and control students for any primary (ever tobacco: OR 1.25, 95% CI 0.92 to 1.68, p=0.14; recent tobacco: OR 1

Predictors of use of alcohol mixed with energy drinks (AmED) among youth have been understudied. The current analyses investigated the prevalence of and correlates for use of AmED among alcohol users from a national study of stimulant use among youth. The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) assessed behaviors and risk factors for stimulant use from 11,048 youth, 10-18 years of age recruited from entertainment venues across 10 US cities. Of the four cross sections, two had questions on having alcohol mixed with energy drinks (AmED) in the past 30 days along with sociodemographic characteristics, current tobacco and marijuana use and current nonmedical use of prescription opioids, anxiolytics, and stimulants. Only 13 to18 year olds and those who reported alcohol use were included in the analyses. Overall, 28.4% (1392 out of 4905) of the 13 to18 year olds reported past 30-day alcohol use. Among alcohol users, 27% reported having alcohol mixed with energy drinks in the past 30 days. Multivariate logistic regression indicated that use of AmED was significantly associated with tobacco and marijuana use and nonmedical use of prescription stimulants. Underage drinking is common among youth and more than a quarter of these drinkers use AmED. Use of AmED is significantly associated with tobacco and marijuana use and nonmedical use of prescription stimulants. Drug and alcohol intervention programs should educate on the risks of AmED, as the same population is at high-risk for use of AmED and alcohol/drug use. Copyright © 2016 Elsevier Ireland Ltd.

Objective Dating violence is a serious and prevalent problem, with females being victimized by partners at high rates with numerous negative health consequences. Previous research has been equivocal on whether substance use on the part of the victim temporally precedes and, thus, increases the odds of victimization. While the sole responsibility for violence is always with the perpetrator, knowing this information could provide useful information for theory as well as interventions designed to keep women safe. Method Participants were female college students in a current dating relationship who had consumed alcohol in the previous month (N = 173). Students completed daily surveys on their violence victimization, alcohol use, and marijuana use for up to 90 consecutive days. Results On any drinking days, heavy drinking days, and as the number of alcoholic drinks consumed increased, women were more likely to be victimized by psychological, physical, and sexual dating violence. Marijuana use also preceded and increased the odds of sexual victimization. Relationship length moderated some of these temporal associations, such that the odds of victimization on a drinking day, or marijuana use day, were increased for participants in longer relationships. Conclusions Findings underscore the importance of considering the role that alcohol and marijuana use play in increasing the risk for dating violence victimization among women. Intervention programs for dating violence may benefit by attempting to decrease substance use in order to reduce risk for female victims. PMID:27818840

Reinforcement of smoking and drinking: tobacco marketing strategies linked with alcohol in the United States.

PubMed

Jiang, Nan; Ling, Pamela M

2011-10-01

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

Gateway to Curiosity: Medical Marijuana Ads and Intention and Use during Middle School

Over the past several years, medical marijuana has received increased attention in the media, and marijuana use has increased across the United States. Studies suggest that as marijuana has become more accessible and adults have become more tolerant regarding marijuana use, adolescents perceive marijuana as more beneficial and are more likely to use if they are living in an environment that is more tolerant of marijuana use. One factor that may influence adolescents’ perceptions about marijuana and marijuana use is their exposure to advertising of this product. We surveyed 6th–8th grade youth in 2010 and 2011 in 16 middle schools in southern California (n= 8214; 50% male; 52% Hispanic; mean age = 13) and assessed exposure to advertising for medical marijuana, marijuana intentions and marijuana use. Cross-lagged regressions showed a reciprocal association of advertising exposure with marijuana use and intentions during middle school. Greater initial medical marijuana advertising exposure was significantly associated with a higher probability of marijuana use and stronger intentions to use one year later, and initial marijuana use and stronger intentions to use were associated with greater medical marijuana advertising exposure one year later. Prevention programs need to better explain medical marijuana to youth, providing information on the context for proper medical use of this drug and the potential harms from use during this developmental period. Furthermore, as this is a new frontier, it is important to consider regulating medical marijuana advertisements, as is currently done for alcohol and tobacco products. PMID:26030167

While marijuana has been legal for medical purposes in California since 1996, little is known about the health histories of young adult medical marijuana patients who are a significant proportion of medical marijuana patients. We examined whether young adult medical marijuana patients reported health conditions and motivations for use that were consistent with medical use of marijuana in California. Young adults (N = 366) aged 18 to 26 years were sampled in Los Angeles in 2014-2015 and segmented into medical marijuana 'patients' (n = 210), marijuana users with a current recommendation, and non-patient users or 'non-patients' (n = 156), marijuana users who never had a medical marijuana recommendation. Differences between patients and non-patients regarding self-reported health histories and past/current motivations for marijuana use were expressed as unadjusted risk ratios. Compared with non-patients, patients were significantly more likely to report a range of lifetime health problems, such as psychological, physical pain and gastrointestinal. In the past 90 days, patients were significantly more likely to report motivations for marijuana use than non-patients concerning sleep, anxiety, physical pain and focusing. Psychological and pain problems were the most common health conditions reported to receive a medical marijuana recommendation. Patients were significantly less likely than non-patients to report any privacy concerns about obtaining a medical marijuana recommendation. Patients were significantly more likely to report a range of health conditions and motivations associated with medical use than non-patients. A great majority of patients reported obtaining a medical marijuana recommendation for health problems in accordance with the California law.

Legalizing Cannabis: A physician's primer on the pulmonary effects of marijuana.

PubMed

2014-01-01

Habitual smoking of marijuana is associated with multiple respiratory symptoms such as cough, sputum production, and wheezing .These symptoms are not significantly different from those exhibited by tobacco smokers. Furthermore, endobronchial biopsies of habitual smokers of marijuana and /or tobacco have shown that both marijuana and cigarette smoking cause significant bronchial mucosal histopathology and that these effects are additive. Although marijuana smokers have minimal changes in pulmonary function studies as compared to tobacco smokers, they may develop bullous disease and spontaneous pneumothoraces. The relationship between marijuana smoking and lung cancer remains unclear due to design limitations of the studies published so far. These findings should warn individuals that marijuana smoking may result in serious short-term and long-term respiratory complications, and habitual marijuana use should be viewed with caution. The medical literature so far does not support routine evaluation by pulmonary function tests or imaging studies; until more definitive data is available, we do not recommend the regular use of these tests in the evaluation of habitual marijuana smokers.

Reassessing policy paradigms: A comparison of the global tobacco and alcohol industries.

PubMed

Hawkins, Benjamin; Holden, Chris; Eckhardt, Jappe; Lee, Kelley

2018-01-01

Tobacco is widely considered to be a uniquely harmful product for human health. Since the mid-1990s, the strategies of transnational tobacco corporations to undermine effective tobacco control policy has been extensively documented through internal industry documents. Consequently, the sale, use and marketing of tobacco products are subject to extensive regulation and formal measures to exclude the industry from policy-making have been adopted in the Framework Convention on Tobacco Control. In contrast to tobacco, alcohol is subject to less stringent forms of regulation, and the alcohol industry continues to play a central role in policy-making in many countries and at the global level. This article examines whether there is a sufficient rationale for such different regulatory approaches, through a comparative analysis of the political economy of the tobacco and alcohol industries including the structure of the industries, and the market and political strategies they pursue. Despite some important differences, the extensive similarities which exist between the tobacco and alcohol industries in terms of market structure and strategy, and political strategy, call into question the rationale for both the relatively weak regulatory approach taken towards alcohol, and the continued participation of alcohol corporations in policy-making processes.

Objective: Motivational interviewing to reduce alcohol and marijuana use among incarcerated adolescents was evaluated. Method: Adolescents (N = 162, 84% male; M = 17.10 years old) were randomly assigned to receive motivational interviewing or relaxation training, with follow-up assessment 3 months after release. Results: Compared with those who received relaxation training, adolescents who received motivational interviewing had lower rates of alcohol and marijuana use at follow-up, with some evidence for moderating effects of depression. At low levels of depression, adolescents who received motivational interviewing had lower rates of use. Adolescents who received relaxation training and who had high levels of depressive symptoms early in incarceration showed less use at follow-up than those low in depressive symptoms who received relaxation training. Conclusions: This brief motivational interviewing intervention during incarceration reduces alcohol and marijuana use after release. In addition, depressive symptoms early in incarceration should be considered in treating these adolescents, but more work is needed to extend follow-up period and account for the impact of depression on outcomes.

No estimation was available for tobacco and for alcohol consumption in Germany based on sales data that were provided for public use and suited for time trend analysis. To estimate trends of tobacco and alcohol consumption rates for the years 1950-2014. Data on tobacco and alcohol consumption in the nation were retrieved from reports made by producers of beer, wine, or spirits to the Federal Statistics Office of Germany. Time trends over the 65 years were calculated using the program Joinpoint. Tobacco consumption rose from 1950 to 1972. Thereafter it decreased, mostly by 1.2-6.9 percentage points per year. Alcohol consumption rose until the year 1974 and decreased thereafter by 1.0 percentage points annually until the end of the time period under analysis in 2014. The findings may be explained, among others, by changes of social norms according to smoking and alcohol consumption after tax increases, nonsmoker and youth protection laws, and legislative measures against driving under the influence of alcohol. A steepening of the decrease in tobacco consumption occurred after laws including tax increases had come into effect. However, the tobacco and alcohol consumption levels were still high at the end of the observation period in 2014. Eigentümer und Copyright ©Georg Thieme Verlag KG 2018.

To determine the extent to which video games include alcohol and tobacco content and assess the association between playing them and alcohol and smoking behaviors in adolescent players in Great Britain. Assessment of substance in the 32 UK bestselling video games of 2012/2013; online survey of adolescent playing of 17 games with substance content; and content analysis of the five most popular games. A total of 1,094 adolescents aged 11-17 years were included as participants. Reported presence of substance content in the 32 games; estimated numbers of adolescents who had played games; self-reported substance use; semiquantitative measures of substance content by interval coding of video game cut scenes. Nonofficial sources reported substance content in 17 (44 percent) games but none was reported by the official Pan European Game Information (PEGI) system. Adolescents who had played at least one game were significantly more likely ever to have tried smoking (adjusted odds ratio [OR] 2.70, 95 percent confidence interval [CI] 1.75-4.17) or consumed alcohol (adjusted OR 2.35, 95 percent CI 1.70-3.23). In the five most popular game episodes of alcohol actual use, implied use and paraphernalia occurred in 31 (14 percent), 81 (37 percent), and 41 (19 percent) intervals, respectively. Tobacco actual use, implied use, and paraphernalia occurred in 32 (15 percent), 27 (12 percent), and 53 (24 percent) intervals, respectively. Alcohol and tobacco content is common in the most popular video games but not reported by the official PEGI system. Content analysis identified substantial substance content in a sample of those games. Adolescents who play these video games are more likely to have experimented with tobacco and alcohol.

Marijuana use and risk of lung cancer: a 40-year cohort study.

Cannabis (marijuana) smoke and tobacco smoke contain many of the same potent carcinogens, but a critical-yet unresolved-medical and public-health issue is whether cannabis smoking might facilitate the development of lung cancer. The current study aimed to assess the risk of lung cancer among young marijuana users. A population-based cohort study examined men (n = 49,321) aged 18-20 years old assessed for cannabis use and other relevant variables during military conscription in Sweden in 1969-1970. Participants were tracked until 2009 for incident lung cancer outcomes in nationwide linked medical registries. Cox regression modeling assessed relationships between cannabis smoking, measured at conscription, and the hazard of subsequently receiving a lung cancer diagnosis. At the baseline conscription assessment, 10.5 % (n = 5,156) reported lifetime use of marijuana and 1.7 % (n = 831) indicated lifetime use of more than 50 times, designated as "heavy" use. Cox regression analyses (n = 44,284) found that such "heavy" cannabis smoking was significantly associated with more than a twofold risk (hazard ratio 2.12, 95 % CI 1.08-4.14) of developing lung cancer over the 40-year follow-up period, even after statistical adjustment for baseline tobacco use, alcohol use, respiratory conditions, and socioeconomic status. Our primary finding provides initial longitudinal evidence that cannabis use might elevate the risk of lung cancer. In light of the widespread use of marijuana, especially among adolescents and young adults, our study provides important data for informing the risk-benefit calculus of marijuana smoking in medical, public-health, and drug-policy settings.

Smoking initiation places adolescents at risk for adult onset diseases, including heart disease, respiratory illness, and cancer. Adolescents that smoke have levels of 'perceived' tobacco addiction that are associated with several measures of nicotine dependence. Nonsmoking adolescents also report feeling addicted to tobacco even with minimal or no prior tobacco use, suggesting some vulnerability to tobacco use. The purpose of this study was to examine the association between perceived tobacco addiction and smoking susceptibility among adolescents with very minimal tobacco use. A cross-sectional analysis was conducted of data obtained from 5155 nonsmokers who completed the British Columbia Youth Survey of Smoking and Health II, a school-based survey conducted during 2004. Measures included demographics, tobacco use (ever puffed a cigarette), substance use (marijuana and alcohol), exposure to family members' smoking in the home, peers' tobacco use, depressive symptoms, perceived physical and mental addiction to tobacco, and smoking susceptibility. The adolescents who were most susceptible to smoking were female, younger and in a lower school grade; had ever puffed a cigarette, had used alcohol or marijuana; had family members or peers who smoked; had higher depression scores, and higher perceived physical and mental addiction to tobacco. In multivariate logistic regression analysis, perceived mental addiction but not perceived physical addiction to tobacco was significantly associated with smoking susceptibility. Understanding factors associated with smoking initiation, and ways to identify "at- risk" adolescents can enhance early intervention and prevention programs. Perceived mental addiction to tobacco appears to be an important indicator of smoking susceptibility.

Tobacco smoking interferes with GABAA receptor neuroadaptations during prolonged alcohol withdrawal

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

A cluster randomised trial of a school-based resilience intervention to decrease tobacco, alcohol and illicit drug use in secondary school students: study protocol

PubMed Central

2012-01-01

Background Whilst schools provide a potentially appropriate setting for preventing substance use among young people, systematic review evidence suggests that past interventions in this setting have demonstrated limited effectiveness in preventing tobacco, alcohol and other drug use. Interventions that adopt a mental wellbeing approach to prevent substance use offer considerable promise and resilience theory provides one method to impact on adolescent mental well-being. The aim of the proposed study is to examine the efficacy of a resilience intervention in decreasing the tobacco, alcohol and illicit drug use of adolescents. Methods A cluster randomised controlled trial with schools as the unit of randomisation will be undertaken. Thirty two schools in disadvantaged areas will be allocated to either an intervention or a control group. A comprehensive resilience intervention will be implemented, inclusive of explicit program adoption strategies. Baseline surveys will be conducted with students in Grade 7 in both groups and again three years later when the student cohort is in Grade 10. The primary outcome measures will include self-reported tobacco, alcohol, marijuana and other illicit drug use. Comparisons will be made post-test between Grade 10 students in intervention and control schools to determine intervention effectiveness across all measures. Discussion To the authors’ knowledge this is the first randomised controlled trial to evaluate the effectiveness of a comprehensive school-based resilience intervention, inclusive of explicit adoption strategies, in decreasing tobacco, alcohol and illicit drug use of adolescents attending disadvantaged secondary schools.

This study used up to seven waves of data from 32 consecutive cohorts of participants in the national longitudinal Monitoring the Future study to model changes in self-reported reasons for using alcohol and marijuana by age (18 to 30), gender, and recent substance use. The majority of stated reasons for use decreased in prevalence across young adulthood (e.g., social/recreational and coping with negative affect reasons); exceptions included age-related increases in using to relax (alcohol and marijuana), to sleep (alcohol), because it tastes good (alcohol), and to get high (marijuana). Women were more likely than men to report drinking for reasons involving distress (i.e., to get away from problems), while men were more likely than women to endorse all other reasons. Greater substance use at age 18 was associated with greater likelihood of all reasons except to experiment and to fit in. A better understanding of developmental changes in reasons for use is important for understanding normative changes in substance use behaviors and for informing intervention efforts involving underlying reasons for use.

The concurrent use of alcohol and tobacco and its deleterious effects have been reported in the western literature. However, studies on the relationship between concurrent alcohol and tobacco use in India are limited. This study outlines the association between concurrent alcohol and tobacco use among a middle-aged and elderly population in a western Indian cohort after controlling for various sociodemographic factors. A total of 35 102 men, 45 years of age and above were interviewed for concurrent alcohol and tobacco use. The sample was part of an earlier cohort drawn from the general population. The data were analysed after controlling for age, education, religion and mother-tongue. Among alcohol users, 51.1% smoked tobacco and 35.6% used smokeless tobacco. The relative risk of alcohol use was highest among those smoking cigarettes or beedis and among those using mishri with betel quid and tobacco. The risk of alcohol use increased with the frequency of tobacco use. The risk also increased with higher amounts of alcohol consumption, but peaked at around 100-150 ml of absolute alcohol use. The study highlights the association between concurrent alcohol and tobacco use among the Indian population. This has important public health implications since concurrent use of these is synergistic for increased risk of oropharyngeal cancers.

Exploring the Link Between Alcohol and Marijuana Use and Teen Dating Violence Victimization Among High School Students: The Influence of School Context.

Adolescence is a developmental period when dating behavior is first initiated and when the risk of abuse by or against a dating partner begins to emerge. It is also one in which experimentation with alcohol and illicit substances typically begins. The current study examined the association between recent alcohol use and recent marijuana use and the experience of physical and verbal teen dating violence (TDV) victimization while considering the potential influence of school contextual variables. Data came from 27,758 high school students attending 58 Maryland public high schools. Hierarchical linear modeling was used to identify student- and school-level predictors associated with TDV. Results indicated that approximately 11% of students reported experiencing physical TDV and 11% of students reported experiencing verbal TDV over the past year. In addition, 33% of students reported recent alcohol use and 21% reported recent marijuana use. Hierarchical linear modeling results revealed that students who reported frequent recent alcohol or recent marijuana use were at increased odds of experiencing physical (adjusted odds ratio [AOR]alcohol = 2.80, p < .001; AORmarijuana = 2.03, p < .001) or verbal TDV (AORalcohol = 2.63, p < .001; AORmarijuana = 2.20, p < .001) victimization compared to students who reported little or no alcohol or marijuana use. School support was a protective factor for both physical TDV (AOR = 0.74, p < .001) and verbal TDV (AOR = 0.76, p < .001) victimization. Findings suggested that prevention efforts to address alcohol and marijuana use may have an effect on TDV victimization. Results also highlight the potential utility of enhancing student perceptions of school support as an approach for reducing TDV victimization. © 2015 Society for Public Health Education.

Cross-sectional research has found that young men who have sex with men (YMSM) are more likely to engage in heavy drinking and to have higher rates of marijuana and other illicit drug use compared to their heterosexual peers, but considerably less is known about their patterns of substance use over time. In this study, we combined two longitudinal samples of racially diverse YMSM (N=552) and modeled their substance use trajectories from late-adolescence to young adulthood, including their frequency of alcohol use, frequency of marijuana use, and poly-drug use, using piecewise latent curve growth modeling to model change from ages 17-21 and change from ages 22-24. We found that all three substance use behaviors increased linearly over the adolescent-to-adult transition. The trajectories for all three substance use behaviors were significantly correlated from ages 17-21. Black YMSM had significantly lower growth from ages 17-21 in alcohol, marijuana, and poly-drug use compared to White YMSM. Hispanic/Latino YMSM had significantly higher growth from ages 22-24 in alcohol use but significantly lower growth in poly-drug use compared to White YMSM. YMSM with higher alcohol frequency slopes and YMSM with higher marijuana use slopes were more likely to have alcohol-related and marijuana-related problems, respectively, at the last wave of the study. The results of the present study suggest that the transition from adolescence to adulthood for YMSM is a time of increasing and co-varying substance use and may be a critical period for substance use behaviors to grow into substance use problems.

Taxes on tobacco, alcohol and sugar sweetened beverages: Linkages and lessons learned.

PubMed

Blecher, Evan

2015-07-01

Increased consumption of sugar-sweetened beverages (SSBs) has been linked to increases in obesity in both high-income and low- and middle-income countries. Tobacco and alcohol taxes have proven to be effective tools to reduce tobacco and alcohol use. Many public health advocates propose using similar taxes to reduce consumption of SSBs. South Africa is a middle-income country that is considered a leader in the area of tobacco tax policy. A case study of tobacco and alcohol taxes is used to better understand optimal tax structures for SSBs. The case study tracks aggregate data over time on taxes, prices, consumption, tax revenues, and marketing expenditures at the brand level. Tobacco and alcohol taxes are shown to be effective in reducing the demand for tobacco. Additionally, taxes on the dose of alcohol rather than the volume of the beverage may incentivize producers to reduce the volume of alcohol in beverages through the supply side. While specific taxes based on the volume of beverages are likely to reduce the demand for SSBs, policy makers should also consider taxes on alcohol and SSBs that tax the dose of the alcohol and calories in order to create supply-side incentives for producers to lower alcohol and calorie levels in existing products or promote products with lower levels of alcohol and calories.

Abstract To determine the extent to which video games include alcohol and tobacco content and assess the association between playing them and alcohol and smoking behaviors in adolescent players in Great Britain. Assessment of substance in the 32 UK bestselling video games of 2012/2013; online survey of adolescent playing of 17 games with substance content; and content analysis of the five most popular games. A total of 1,094 adolescents aged 11–17 years were included as participants. Reported presence of substance content in the 32 games; estimated numbers of adolescents who had played games; self-reported substance use; semiquantitative measures of substance content by interval coding of video game cut scenes. Nonofficial sources reported substance content in 17 (44 percent) games but none was reported by the official Pan European Game Information (PEGI) system. Adolescents who had played at least one game were significantly more likely ever to have tried smoking (adjusted odds ratio [OR] 2.70, 95 percent confidence interval [CI] 1.75–4.17) or consumed alcohol (adjusted OR 2.35, 95 percent CI 1.70–3.23). In the five most popular game episodes of alcohol actual use, implied use and paraphernalia occurred in 31 (14 percent), 81 (37 percent), and 41 (19 percent) intervals, respectively. Tobacco actual use, implied use, and paraphernalia occurred in 32 (15 percent), 27 (12 percent), and 53 (24 percent) intervals, respectively. Alcohol and tobacco content is common in the most popular video games but not reported by the official PEGI system. Content analysis identified substantial substance content in a sample of those games. Adolescents who play these video games are more likely to have experimented with tobacco and alcohol.

BACKGROUND Abundant cross-sectional evidence links eveningness (a preference for later sleep-wake timing) and increased alcohol and drug use among adolescents and young adults. However, longitudinal studies are needed to examine whether eveningness is a risk factor for subsequent alcohol and drug use, particularly during adolescence, which is marked by parallel peaks in eveningness and risk for the onset of alcohol use disorders. The present study examined whether eveningness and other sleep characteristics were associated with concurrent or subsequent substance involvement in a longitudinal study of adolescents. METHODS Participants were 729 adolescents (368 females; age 12–21 years) in the National Consortium on Adolescent Neurodevelopment and Alcohol [NCANDA] study. Associations between the sleep variables (circadian preference, sleep quality, daytime sleepiness, sleep timing, and sleep duration) and three categorical substance variables (at-risk alcohol use, alcohol bingeing, and past year marijuana use (y/n)) were examined using ordinal and logistic regression with baseline age, sex, race, ethnicity, socioeconomic status, and psychiatric problems as covariates. RESULTS At baseline, greater eveningness was associated with greater at-risk alcohol use, greater bingeing, and past-year use of marijuana. Later weekday and weekend bedtimes, but not weekday or weekend sleep duration, showed similar associations across the three substance outcomes at baseline. Greater baseline eveningness was also prospectively associated with greater bingeing and past-year use of marijuana at the 1-year follow-up, after covarying for baseline bingeing and marijuana use. Later baseline weekday and weekend bedtimes, and shorter baseline weekday sleep duration, were similarly associated with greater bingeing and past-year use of marijuana at the 1-year follow-up after covarying for baseline values. CONCLUSIONS Findings suggest that eveningness and sleep timing may be under

Appalachia has high rates of tobacco use and related health problems, and despite significant impediments to alcohol use, alcohol abuse is common. Adolescents are exposed to sophisticated tobacco and alcohol advertising. Prevention messages, therefore, should reflect research concerning culturally influenced attitudes toward tobacco and alcohol use. With 4 grants from the National Institutes of Health, 34 focus groups occurred between 1999 and 2003 in 17 rural Appalachian jurisdictions in 7 states. These jurisdictions ranged between 4 and 8 on the Rural-Urban Continuum Codes of the Economic Research Service of the US Department of Agriculture. Of the focus groups, 25 sought the perspectives of women in Appalachia, and 9, opinions of adolescents. The family represented the key context where residents of Appalachia learn about tobacco and alcohol use. Experimentation with tobacco and alcohol frequently commenced by early adolescence and initially occurred in the context of the family home. Reasons to abstain from tobacco and alcohol included a variety of reasons related to family circumstances. Adults generally displayed a greater degree of tolerance for adolescent alcohol use than tobacco use. Tobacco growing represents an economic mainstay in many communities, a fact that contributes to the acceptance of its use, and many coal miners use smokeless tobacco since they cannot light up in the mines. The production and distribution of homemade alcohol was not a significant issue in alcohol use in the mountains even though it appeared not to have entirely disappeared. Though cultural factors support tobacco and alcohol use in Appalachia, risk awareness is common. Messages tailored to cultural themes may decrease prevalence.

Purpose Using prospective longitudinal data from 3 generations, this study seeks to test whether and how parent and grandparent marijuana use (current and prior) predicts an increased likelihood of child cigarette, alcohol, and marijuana use. Methods Using multilevel modeling of prospective data spanning 3 generations (N = 306 families, children ages 6-22), this study tested associations between grandparent (G1) and parent (G2) marijuana use and child (G3) past-year cigarette, alcohol, and marijuana use. Analyses tested whether G3 substance-related norms mediated these associations. Current G1 and G2 marijuana use was examined, as was G2 high school and early adult use and G1 marijuana use when G2 parents were in early adolescence. Controls included G2 age at G3 birth, G2 education and depression, and G3 gender. Results G2 current marijuana use predicted a higher likelihood of G3 alcohol and marijuana use, but was not related to the probability of G3 cigarette use. G3's perceptions of their parents' norms and G2 current marijuana use both contributed independently to the likelihood of G3 alcohol and marijuana use when included in the same model. G3 children's own norms and their perceptions of friends' norms mediated the link between G2 current marijuana use and G3 alcohol and marijuana use. Conclusions Results are discussed in light of the growing trend toward marijuana legalization. To the extent that parent marijuana use increases under legalization, we can expect more youth to use alcohol and marijuana and to have norms that favor substance use. PMID:27265424

Advertising influences people's health behaviors. Tobacco companies have linked tobacco and alcohol in their marketing activities. We examined how depictions of alcohol were placed in lifestyle magazines produced by tobacco companies, and if these references differed depending on if the magazine was oriented towards men, women, or if it was unisex. Content analysis of 6 different tobacco industry lifestyle magazines (73 issues), including 73 magazine covers, 1558 articles, 444 tobacco ads, and 695 non-tobacco ads. 14 of 73 (19%) magazine covers featured alcohol; 581 of 1558 (37%) magazine articles mentioned alcohol; 119 of 444 (27%) tobacco ads showed alcohol images; and 57 of 695 (8%) non-tobacco ads portrayed alcohol. Male-oriented magazines ( Unlimited , CML , and Real Edge ) contained the most alcohol references, and the references were mainly beer, mixed drinks, and liquor or spirits. Female-oriented magazines ( All Woman and Flair ) contained the fewest alcohol references, and wine and mixed drinks were the major types of alcoholic beverage portrayed. For unisex magazine ( P.S. ), the frequency of alcohol references fell between the male- and female-oriented magazines, and most frequently mentioned mixed drinks. Frequent depictions of smoking and drinking in tobacco industry lifestyle magazines might have reinforced norms about paired use of tobacco and alcohol among young adults. The pairing of tobacco and alcohol may particularly target young men. Anti-tobacco interventions need to address the co-use of tobacco and alcohol, change the social acceptability of smoking in any social settings, and tailor alcohol related anti-tobacco messaging by gender.

To describe the use of marijuana and alcohol among Arabic- and Vietnamese-speaking senior school students compared with English-speaking background senior school students in Sydney Australia. A quantitative survey of 2573 school students attending Years 10 and 11 from 12 high schools with a high Vietnamese and Arabic population was conducted in Sydney in 1998. Self-reported marijuana use, school and cultural background information was collected. Students from an English-speaking background, both males and females, had almost double the prevalence of marijuana use (once or more) during their lifetime (48.3 and 43.6%), the 12 months (40.9 and 36.3%) and 1 month prior to survey administration (23.1 and 13.4%) than the group with the second highest frequency of use (students of European and other backgrounds). Female Vietnamese (7.3% lifetime use) and Arabic students (8.6% lifetime use) had the lowest marijuana use rates, which were less than half that of male Vietnamese (23.5% lifetime use) and Arabic students (28% lifetime use). A similar pattern was found for three types of alcohol use. Spending three or more evenings a week out with friends was associated with higher alcohol use for Vietnamese students (relative risk ratio of 2.76). These results confirm lower marijuana and alcohol use among students from Vietnamese- and Arabic-speaking backgrounds compared with students from an English-speaking background. Harm minimization strategies may be learned from some migrant communities.

Background Despite the high prevalence of smoking among Aboriginal youth, there is a paucity of research related to tobacco use and other risk behaviours among Aboriginal youth living off-reserve in Canada. We used data from the national Youth Smoking Survey to characterize non-traditional tobacco use, exposure to second-hand smoke, and alcohol and drug use among Aboriginal youth living off-reserve. We examined whether these youth were at increased health risk compared with non-Aboriginal youth. Methods We examined cigarette smoking behaviour, use of other tobacco products, use of alcohol and other drugs, and exposure to second-hand smoke among 2620 Aboriginal youth living off-reserve and 26 223 non-Aboriginal youth in grades 9 to 12 who participated in the 2008/09 Youth Smoking Survey. Results The prevalence of current smoking among the Aboriginal youth was more than double that among non-Aboriginal youth (24.9% v. 10.4%). Aboriginal youth also had a higher prevalence of regular exposure to second-hand smoke at home (37.3% v. 19.7%) and in cars (51.0% v. 30.3%). Aboriginal youth were more likely than non-Aboriginal youth to be current smokers, to be regularly exposed to second-hand smoke, to have tried marijuana and other illicit drugs, and to engage in binge drinking. They were less likely than non-Aboriginal youth to have tried to quit smoking. Interpretation Current national estimates of smoking, and alcohol and illicit drug use among youth underestimate the prevalence of these behaviours among Aboriginal youth living off-reserve. Our findings highlight the need for culturally appropriate prevention and cessation policies and programs for this at-risk population. PMID:21555383

2014-05-01

This article examines noncausal associations between high school seniors' alcohol and marijuana use status and rates of self-reported unsafe driving in the past 12 months. Analyses used data from 72,053 students collected through annual surveys of nationally representative cross-sectional samples of U.S. 12th-grade students from 1976 to 2011. Two aspects of past-12-month alcohol and marijuana use were examined: (a) use frequency and (b) status as a nonuser, single substance user, concurrent user, or simultaneous user. Measures of past-12-month unsafe driving included any tickets/warnings or accidents, as well as tickets/warnings or accidents following alcohol or marijuana use. Analyses explored whether an individual's substance use frequency and simultaneous use status had differential associations with their rate of unsafe driving. Higher substance use frequency (primarily alcohol use frequency) was significantly and positively associated with unsafe driving. The rate of engaging in any unsafe driving was also significantly and positively associated with simultaneous use status, with the highest rate associated with simultaneous use, followed by concurrent use, followed by use of alcohol alone. Individuals who reported simultaneous use most or every time they used marijuana had the highest likelihood of reporting unsafe driving following either alcohol or marijuana use. This article expands the knowledge on individual risk factors associated with unsafe driving among teens. Efforts to educate U.S. high school students (especially substance users), parents, and individuals involved in prevention programming and driver's education about the increased risks associated with various forms of drug use status may be useful.

Parental Restriction of Movie Viewing Prospectively Predicts Adolescent Alcohol and Marijuana Initiation: Implications for Media Literacy Programs.

Cox, Melissa J; Gabrielli, Joy; Janssen, Tim; Jackson, Kristina M

Youth are heavy consumers of media, and exposure to mature media content is associated with initiation and progression of substance use. Parental restriction of such content has been shown to be an effective mechanism to reduce negative consequences attributed to exposure to mature media content. This study assessed the influence of parental restriction of movie watching across Motion Picture Association of America rating categories on subsequent alcohol and marijuana initiation at 1- and 2-year follow-up. Using data from a longitudinal study of adolescent substance use (N = 1023), we used logistic regression analyses to determine the odds of alcohol and marijuana initiation across movie rating categories, within R-rated restriction categories in particular, and based on changes in parental restriction of movies over time. All analyses controlled for important parental, personality, and behavioral correlates of adolescent substance use. Results suggest that restriction of R-rated movies is protective of both alcohol and marijuana initiation. Important differences among parental restriction of R-rated movie categories emerged such that being allowed to watch them with adult supervision was protective of substance use, while those who reported watching R-rated films despite parental restrictions were at heightened risk for alcohol initiation. Changes in parental movie restrictions were not predictive of substance use initiation over the subsequent year. Implications of these findings for media literacy program prevention strategies are discussed.

Age-related changes in reasons for using alcohol and marijuana from ages 18 to 30 in a national sample.

This study used up to seven waves of data from 32 consecutive cohorts of participants in the national longitudinal Monitoring the Future study to model changes in self-reported reasons for using alcohol and marijuana by age (18 to 30), gender, and recent substance use. The majority of stated reasons for use decreased in prevalence across young adulthood (e.g., social/recreational and coping with negative affect reasons); exceptions included age-related increases in using to relax (alcohol and marijuana), to sleep (alcohol), because it tastes good (alcohol), and to get high (marijuana). Women were more likely than men to report drinking for reasons involving distress (i.e., to get away from problems), while men were more likely than women to endorse all other reasons. Greater substance use at age 18 was associated with greater likelihood of all reasons except to experiment and to fit in. A better understanding of developmental changes in reasons for use is important for understanding normative changes in substance use behaviors and for informing intervention efforts involving underlying reasons for use.

Justice-involved youth have high rates of alcohol and marijuana use. However, little is known about what may drive these rates over time. Using a large-scale (N=1,056; 41.4% African-American, 33.5% Hispanic) longitudinal study with strong retention (M retention = 90% over Years 1–7), we utilized random-effects regression to determine the comparative contribution of four sets of factors in justice-involved males’ patterns of marijuana and heavy alcohol use (number of times drunk) over the seven years of follow-up: demographic, personality, situational, and neuropsychological factors. Across both marijuana and heavy alcohol use models, three factors were particularly strong contributors to lower rates of substance use: (1) Hispanic ethnicity, (2) less exposure (street) time, and (3) better impulse control. Similarly, two factors were strong contributors to increased rates of marijuana and heavy alcohol use: (1) delinquent peers and (2) family member arrest. Together, these findings indicate the relative superiority of these independent variables over other categories (i.e., neuropsychological factors) in predicting high-risk youths’ long term (seven year) rates of substance use. These findings also suggest the importance of evaluating the connection of these areas for high-risk, adjudicated youth. PMID:26030166

Depiction of alcohol, tobacco, and other substances in G-rated animated feature films.

2001-06-01

To quantify and characterize the depiction of alcohol, tobacco, and other substances in G-rated animated feature films. The content of all G-rated animated feature films released in theaters between 1937 and 2000, recorded in English, and available on videocassette in the United States by October 31, 2000, was reviewed for portrayals of alcohol, tobacco, and other substances and their use. Duration of scenes depicting alcohol, tobacco, or other substances; type of characters using them (good, neutral, or bad); and correlation of amount and type used with character type and movie type were evaluated. Of the 81 films reviewed, 38 films (47%) showed alcohol use (mean exposure: 42 seconds per film; range: 2 seconds to 2.9 minutes) and 35 films (43%) showed tobacco use (mean exposure: 2.1 minutes per film; range: 2 seconds to 10.5 minutes). Analysis of time trends showed a significant decrease in both tobacco and alcohol use over time (both corrected for total screen duration and uncorrected.) No films showed the use of illicit drugs, although 3 films showed characters consuming a substance that transfigured them and 2 films showed characters injected with a drug. Analysis of the correlation of alcohol and tobacco depiction revealed several scenes in which alcohol and tobacco were shown in use in the same scene and that bar scenes in these movies depict a significant amount of drinking, smoking, and violence. Three films contained a message that a character should stop smoking but none contained messages about restricting consumption of alcohol. The depiction of alcohol and tobacco use in G-rated animated films seems to be decreasing over time. Nonetheless, parents should be aware that nearly half of the G-rated animated feature films available on videocassette show alcohol and tobacco use as normative behavior and do not convey the long-term consequences of this use.

Litigation and alcohol policy: lessons from the US Tobacco Wars.

Mosher, James F

2009-02-01

This paper explores the role of litigation in preventing alcohol-related harms, identifying lessons from the use of litigation in tobacco control policy in the United States. It analyzes the key components of litigation in an international context, provides a case study of its potential use in addressing the marketing of alcopops to youth and offers recommendations for pursuing litigation strategies in future alcohol policy efforts. The paper's analyses are based on both original and secondary legal research. State and federal case law and secondary sources are reviewed in assessing lessons learned from tobacco litigation in the United States and the potential role of litigation in alcohol policy, both in the United States and internationally. Assessment of alcohol litigation cases and state and federal laws and regulations provides the foundation for the alcopops case study. The tobacco litigation experience demonstrates that litigation is a powerful tool in addressing aggressive marketing by purveyors of addictive products such as alcohol. To be effective at both national and international levels, litigation should encompass a broad array of legal tactics designed to identify and restrict unfair, deceptive and misleading alcohol marketing tactics and should be utilized in conjunction with complementary prevention strategies. Research conducted on the impact of alcohol marketing on youth alcohol consumption and problems is needed to support potential litigation claims. Developing litigation expertise within the alcohol policy field and building collaboration with litigation specialists in tobacco control should also be considered a high priority.

This study examined whether marijuana use was associated with clinically problematic outcomes for patients with depression and alcohol use disorder (AUD). The sample consisted of 307 psychiatry outpatients with mild to severe depression and past 30-day hazardous drinking/drug use, who participated in a trial of substance use treatment. Participants were assessed for AUD based on DSM-IV criteria. Measures of marijuana use, depression symptoms, and functional status related to mental health were collected at baseline, 3, and 6 months. Differences in these outcomes were analyzed among patients with and without AUD using growth models, adjusting for treatment effects. Marijuana was examined as both an outcome (patterns of use) and a predictor (impact on depression and functioning). Forty percent used marijuana and about half the sample met AUD criteria. Fewer patients with AUD used marijuana than those without AUD at baseline. Over 6 months, the proportion of patients with AUD using marijuana increased compared to those without AUD. Patients with AUD using marijuana had greater depressive symptoms and worse functioning than those without AUD. These findings indicate that marijuana use is clinically problematic for psychiatry outpatients with depression and AUD. Addressing marijuana in the context of psychiatry treatment may help improve outcomes. Copyright © 2017 Elsevier B.V. All rights reserved.

Alcohol and tobacco marketing: An evaluation of compliance with restrictions on outdoor ads

Scott, Molly M; Cohen, Deborah A; Schonlau, Matthias; Farley, Thomas A; Bluthenthal, Ricky

2010-01-01

Background Historically, the alcohol and tobacco industries have been the biggest users of outdoor advertising. However, the 1999 Master Settlement Agreement (MSA) outlawed tobacco billboards and transit furniture ads and the Outdoor Advertising Association of America (OAAA) has pledged to voluntarily eliminate ads for alcohol and tobacco within 500 feet of schools, playgrounds, and churches. Methods We observed outdoor advertisements (2004–2005) in a sample of 106 urban census tracts in Pre-Katrina southern Louisiana and 114 in Los Angeles County to evaluate tobacco and alcohol advertisers’ compliance with the MSA and the OAAA Code of Principles. Data were analyzed in 2007–2008. Results More than 1 in 4 tobacco ads in Louisiana failed to comply with the MSA. In Los Angeles, 37% of alcohol ads and 25% of tobacco ads were located within 500 feet of a school, park, or church; in Louisiana, roughly 1 in 5 ads promoting alcohol or tobacco fell within this distance. In Los Angeles, low-income status and the presence of a freeway in the tract were associated with 40% more alcohol and tobacco billboards near children. In Louisiana, each additional major roadway-mile was associated with 4% more tobacco ads in violation of MSA and 7% more small ads near schools, parks, and churches; city jurisdiction accounted for 55% of MSA violations and more than 70% violations of OAAA guidelines. Conclusions Cities must be empowered to deal locally with violations of the MSA. Legislation is needed to force advertisers to honor their pledge to protect children from alcohol and tobacco ads.

2001-06-01

The association between sexual abstinence and use of alcohol, cigarettes, and marijuana was examined in data from questionnaires completed by 874 students in Grades 6 through 8 at six urban schools. These students participated in a program that implemented and evaluated an educational program on abstinence sexuality. It focused on raising self-esteem, improving communication skills, and learning to set life goals. The evaluation instrument contained items assessing sexuality and attitudes toward behaviors related to drug use. Use of each drug (alcohol, tobacco, and marijuana) was significantly (p < .00001) and positively associated with self-report of having experienced sexual intercourse and expectation of having intercourse during the next year.

2015-10-05

There is a strong socio-economic gradient in both tobacco-and alcohol-related harm. One possible factor contributing to this social gradient may be greater availability of tobacco and alcohol in more socially-deprived areas. A higher density of tobacco and alcohol outlets is not only likely to increase supply but also to raise awareness of tobacco/alcohol brands, create a competitive local market that reduces product costs, and influence local social norms relating to tobacco and alcohol consumption. This paper examines the association between the density of alcohol and tobacco outlets and neighbourhood-level income deprivation. Using a national tobacco retailer register and alcohol licensing data this paper calculates the density of alcohol and tobacco retail outlets per 10,000 population for small neighbourhoods across the whole of Scotland. Average outlet density was calculated for neighbourhoods grouped by their level of income deprivation. Associations between outlet density and deprivation were analysed using one way analysis of variance. There was a positive linear relationship between neighbourhood deprivation and outlets for both tobacco (p <0.001) and off-sales alcohol (p <0.001); the most deprived quintile of neighbourhoods had the highest densities of both. In contrast, the least deprived quintile had the lowest density of tobacco and both off-sales and on-sales alcohol outlets. The social gradient evident in alcohol and tobacco supply may be a contributing factor to the social gradient in alcohol- and tobacco-related disease. Policymakers should consider such gradients when creating tobacco and alcohol control policies. The potential contribution to public health, and health inequalities, of reducing the physical availability of both alcohol and tobacco products should be examined in developing broader supply-side interventions.

Objective To investigate whether risk factors for cigarette smoking assessed in adolescence predict the use of novel tobacco and nicotine products (hookah, little cigars, and e-cigarettes) in early emerging adulthood. Methods In a longitudinal study (N = 862), risk factors were measured in middle and high school and novel product use was measured in emerging adulthood (mean age 22.4 years). Structural equation modelling was used to test a model predicting lifetime use of any of hookah, little cigars, and e-cigarettes in early emerging adulthood from distal predictors (gender, maternal smoking through Grade 8, already tried alcohol, cigarettes, or marijuana by Grade 8, and sensation seeking at Grade 8), and potential mediators (intentions to smoke cigarettes, drink alcohol or smoke marijuana at Grade 9, and smoking trajectory across high school). Results The most prevalent novel tobacco product was hookah (21.7%), followed by little cigars (16.8%), and e-cigarettes (6.6%). Maternal smoking, having already tried substances, and sensation seeking each predicted the use of at least one of these products via an indirect path through intentions to use substances and membership in a high school smoking trajectory. Conclusions Risk factors for cigarette smoking were found to predict novel tobacco use, suggesting that interventions to prevent cigarette smoking could be extended to include common novel tobacco products.

Objective Young adults frequently report social smoking. This study examined the relationship between different social smoking definitions and the co-use of cigarettes and alcohol, tobacco-related attitudes, and quitting efforts. Method Cross-sectional data were collected at bars using randomized time location sampling among young adults aged 21–26 in San Diego, CA from 2010–2011 (73% response rate). Multivariable logistic regression examined if current smoking and quit attempts were associated with tobacco-related attitudes, and whether social smoking self-identification or behavior was associated with cigarette-and-alcohol co-use, tobacco-related attitudes, quit attempts, or quitline use. Results Among 537 current smokers, 80% self-identified and 49% behaved as social smokers. Social smoking self-identification was positively associated with cigarette-and-alcohol co-use, and quit attempts. Social smoking behavior was negatively associated with tobacco marketing receptivity, quit attempts, quitline use. Tobacco-related attitudes were associated with smoking but did not generally differ by social smoking status. Conclusion Identification and behavior as a social smoker have opposing associations with co-use of cigarettes and alcohol and quit attempts. Tobacco cessation programs for self-identified social smokers should address co-use. Interventions denormalizing the tobacco industry or emphasizing the health effects of temporary smoking/secondhand smoke may address smoking among young adult bar patrons regardless of social smoking status.

Tobacco and alcohol use in movies could be influenced by product placement agreements. Tobacco brand placement was limited by the Master Settlement Agreement (MSA) after 1998, while alcohol is subject to self-regulation only. To examine recent trends for tobacco and alcohol use in movies. We expected that the MSA would be associated with declines in tobacco but not alcohol brand placement (hypothesis formulated after data collection). Content analysis. Top 100 box-office hits released in the United States from 1996 through 2009 (N = 1400). The MSA, an agreement signed in 1998 between the state attorneys general and tobacco companies, ended payments for tobacco brand placements in movies. Trend for tobacco and alcohol brand counts and seconds of screen time for the pre-MSA period from 1996 through 1999 compared with the post-MSA period from 2000 through 2009. Altogether, the 1400 movies contained 500 tobacco and 2433 alcohol brand appearances. After implementation of the MSA, tobacco brand appearances dropped exponentially by 7.0% (95% CI, 5.4%-8.7%) each year, then held at a level of 22 per year after 2006. The MSA also heralded a drop in tobacco screen time for youth- and adult-rated movies (42.3% [95% CI, 24.1%-60.2%] and 85.4% [56.1%-100.0%], respectively). In contrast, there was little change in alcohol brand appearances or alcohol screen time overall. In addition, alcohol brand appearances in youth-rated movies trended upward during the period from 80 to 145 per year, an increase of 5.2 (95% CI, 2.4-7.9) appearances per year. Tobacco brands in movies declined after implementation of externally enforced constraints on the practice, coinciding also with a decline in tobacco screen time and suggesting that enforced limits on tobacco brand placement also limited onscreen depictions of smoking. Alcohol brand placement, subject only to industry self-regulation, was found increasingly in movies rated for youth as young as 13 years, despite the industry's intent to

Combined use of marijuana (MJ) and tobacco is highly prevalent in today's population. Individual use of either substance is linked to structural brain changes and altered cognitive function, especially with consistent reports of hippocampal volume deficits and poorer memory performance. However, the combined effects of MJ and tobacco on hippocampal structure and on learning and memory processes remain unknown. In this study, we examined both the individual and combined effects of MJ and tobacco on hippocampal volumes and memory performance in four groups of adults taken from two larger studies: MJ-only users (n=36), nicotine-only (Nic-only, n=19), combined marijuana and nicotine users (MJ+Nic, n=19) and non-using healthy controls (n=16). Total bilateral hippocampal volumes and memory performance (WMS-III logical memory) were compared across groups controlling for total brain size and recent alcohol use. Results found MJ and MJ+Nic groups had smaller total hippocampal volumes compared to Nic-only and controls. No significant difference between groups was found between immediate and delayed story recall. However, the controls showed a trend for larger hippocampal volumes being associated with better memory scores, while MJ+Nic users showed a unique inversion, whereby smaller hippocampal volume was associated with better memory. Overall, results suggest abnormalities in the brain-behavior relationships underlying memory processes with combined use of marijuana and nicotine use. Further research will need to address these complex interactions between MJ and nicotine. Copyright © 2015 The Authors. Published by Elsevier B.V. All rights reserved.

Fleming, Charles B.; Guttmannova, Katarina; Cambron, Christopher; Rhew, Isaac C.; Oesterle, Sabrina

Purpose As marijuana laws have become more permissive, survey data on adolescents in the United States have shown an increase in marijuana-specific risk factors, particularly in the proportion of youth who do not perceive marijuana use as harmful. Prevalence of marijuana use among youth, however, has changed little. Using representative data from Washington State, which has legalized medical and nonmedical marijuana for adults, we examined two competing hypotheses to account for this divergence in population trends. Methods Data were from 2000 – 2014 biennial Washington State surveys of 10th-grade students. First, we assessed whether associations between marijuana use and marijuana-specific risk factors have weakened over time. Second, we examined whether decreases in alcohol and cigarette use can account for the lack of expected increase in marijuana use prevalence. Results Despite stability in marijuana use prevalence, there were increases in marijuana-specific risk factors of low perceived harm, youth favorable attitudes about use, and perceived community attitudes favorable to use. Associations between marijuana use and marijuana-use predictors varied little across time; if anything, the positive association between low perceived harm and marijuana use grew stronger. Decreases in prevalence of alcohol and cigarette use largely accounted for stability in marijuana use during a period when marijuana risk factors increased. Conclusions Decreases in other types of substance use or in the underlying, common risk for substance use may have mitigated effects of increases in marijuana-specific risk factors. PMID:27318426

We identified, in subjects with first-episode psychosis, demographic and socioenvironmental predictors of three variables pertaining to premorbid marijuana use: age at initiation of marijuana use, trajectories of marijuana use in the five years prior to onset of psychosis, and the cumulative "dose" of marijuana intake in that same premorbid period. We enrolled 247 first-episode psychosis patients and collected data on lifetime marijuana/alcohol/tobacco use, age at onset of psychosis, diverse socioenvironmental variables, premorbid adjustment, past traumatic experiences, perceived neighborhood-level social disorder, and cannabis use experiences. Bivariate tests were used to examine associations between the three premorbid marijuana use variables and hypothesized predictors. Regression models determined which variables remained independently significantly associated. Age at initiation of cigarette smoking was linked to earlier initiation, faster escalation, and higher cumulative dose of premorbid marijuana use. During childhood, poorer academic performance was predictive of an earlier age at initiation of marijuana use, while poorer sociability was related to more rapid escalation to daily use and a higher cumulative dose. As expected, experiencing euphoric effects was positively correlated with trajectories and cumulative dose, but having negative experiences was unrelated. Traumatic childhood/adolescent experiences were correlated with rapid escalation and amount of marijuana used, but not with age at initiation of marijuana use. These data expand the very limited literature on predictors of premorbid marijuana use in first-episode psychosis. Given its association with earlier age at onset of psychosis, and poorer outcomes among first-episode patients, prevention and treatment efforts should be further developed.

Executive functioning (EF), an umbrella construct encompassing gradual maturation of cognitive organization/management processes, is important to success in multiple settings including high school. Intrauterine tobacco exposure (IUTE) correlates with negative cognitive/behavioral outcomes, but little is known about its association with adolescent EF and information from real-life contexts is sparse. We evaluated the impact of IUTE on teacher-reported observations of EF in urban high school students controlling for covariates including other intrauterine and adolescent substance exposures. A prospective low-income birth cohort (51% male; 89% African American/Caribbean) was followed through late adolescence (16-18 years old). At birth, intrauterine exposures to cocaine and other substances (52% cocaine, 52% tobacco, 26% marijuana, 26% alcohol) were identified by meconium and/or urine assays, and/or maternal self-report. High school teachers knowledgeable about the student and unaware of study aims were asked to complete the Behavior Rating Inventory of Executive Functioning-Teacher Form (BRIEF-TF) annually. Teachers completed at least one BRIEF-TF for 131 adolescents. Multivariable analyses included controls for: demographics; intrauterine cocaine, marijuana, and alcohol exposures; early childhood exposures to lead; and violence exposure from school-age to adolescence. IUTE was associated with less optimal BRIEF-TF Behavioral Regulation scores (p <0.05). Other intrauterine substance exposures did not predict less optimal BRIEF-TF scores, nor did exposures to violence, lead, nor adolescents' own substance use. IUTE is associated with offspring's less optimal EF. Prenatal counseling should emphasize abstinence from tobacco, as well as alcohol and illegal substances. Copyright © 2017 Elsevier B.V.

Use of Marijuana and Other Substances Among Pregnant and Parenting Women With Substance Use Disorders: Changes in Washington State After Marijuana Legalization.

PubMed

Grant, Therese M; Graham, J Christopher; Carlini, Beatriz H; Ernst, Cara C; Brown, Natalie Novick

2018-01-01

In 2012, possession of marijuana for nonmedical use was legalized in Washington State. This study examined how legalization affected alcohol and drug use in a sample of pregnant and parenting women with substance use disorders. Study participants from nine counties in Washington State (N = 1,359) were questioned about their substance use after completing a 3-year case management intervention program. The sample was divided into two cohorts based on whether participants had completed the program before or after legalization. Most study participants reported complete abstinence from alcohol and nonprescription drugs at program exit. Among those who were still using substances, women who completed the intervention after marijuana legalization were significantly more likely to report marijuana use at program exit compared with women who completed the intervention before marijuana legalization. Across both cohorts (pre- and post-legalization), we found a positive association of exit marijuana use with alcohol, illegal methadone, other opioids, amphetamines, and cocaine use; even when we controlled for historical period, the association with some of these substances with marijuana use remained evident. Independent of marijuana use, we saw increased use during the post-legalization period of alcohol, illicit methadone, and other opioids. Marijuana use at exit from the Parent-Child Assistance Program (PCAP) increased significantly after marijuana legalization in the state. Women who were not abstinent from marijuana at program exit were likely to report use of other substances as well. Our study design demonstrates an association but does not allow us to conclude that marijuana use leads to other substance use among this sample of women with a history of polysubstance use.

Alert out on tobacco and alcohol consumption in young European women.

Thibaut, Florence

2018-05-08

Europe is the heaviest drinking and smoking region in the world. Tobacco and alcohol use are gradually increasing in women with a close prevalence of tobacco and heavy alcohol use in girls and boys. Pharmacokinetics and pharmacodynamics differences, reward process specificities and female hormones play a major role in gender differences in addictive behaviors. Therefore, health consequences differ according to gender. Further research is needed on gender differences in addiction. Information, education on the impact of hazardous alcohol consumption and related harm as well as on the consequences of tobacco use is urgently required in girls and childbearing age women.

Abstract Aims To quantify tobacco and alcohol content, including branding, in popular contemporary YouTube music videos; and measure adolescent exposure to such content. Design Ten‐second interval content analysis of alcohol, tobacco or electronic cigarette imagery in all UK Top 40 YouTube music videos during a 12‐week period in 2013/14; on‐line national survey of adolescent viewing of the 32 most popular high‐content videos. Setting Great Britain. Participants A total of 2068 adolescents aged 11–18 years who completed an on‐line survey. Measurements Occurrence of alcohol, tobacco and electronic cigarette use, implied use, paraphernalia or branding in music videos and proportions and estimated numbers of adolescents who had watched sampled videos. Findings Alcohol imagery appeared in 45% [95% confidence interval (CI) = 33–51%] of all videos, tobacco in 22% (95% CI = 13–27%) and electronic cigarettes in 2% (95% CI = 0–4%). Alcohol branding appeared in 7% (95% CI = 2–11%) of videos, tobacco branding in 4% (95% CI = 0–7%) and electronic cigarettes in 1% (95% CI = 0–3%). The most frequently observed alcohol, tobacco and electronic cigarette brands were, respectively, Absolut Tune, Marlboro and E‐Lites. At least one of the 32 most popular music videos containing alcohol or tobacco content had been seen by 81% (95% CI = 79%, 83%) of adolescents surveyed, and of these 87% (95% CI = 85%, 89%) had re‐watched at least one video. The average number of videos seen was 7.1 (95% CI = 6.8, 7.4). Girls were more likely to watch and also re‐watch the videos than boys, P < 0.001. Conclusions Popular YouTube music videos watched by a large number of British adolescents, particularly girls, include significant tobacco and alcohol content, including branding. PMID:25516167

The prospective effects of impulsivity on alcohol and tobacco use in a college sample.

PubMed

Doran, Neal; Trim, Ryan S

2013-01-01

Alcohol and tobacco use are strongly associated, particularly in younger populations, and concurrent use may encourage progression toward dependence on both substances. Impulsivity has been linked to the use of alcohol and tobacco individually, but has not been studied in terms of its association with use of both. This study tested the hypothesis that the effects of impulsivity (sensation seeking and negative urgency) on smoking initiation in a sample of college students (n = 400) would be mediated by alcohol consumption. We also predicted that sensation seeking and negative urgency would predict alcohol and cigarette use and overlap among initiators. Sensation seeking and negative urgency both predicted smoking initiation, but only the former effect was mediated by alcohol use. Among initiators, sensation seeking was associated with more frequent alcohol use as well as more frequent overlap between alcohol and tobacco use but not with smoking frequency. Higher negative urgency was associated with more frequent smoking, but not with alcohol use or alcohol/tobacco overlap. Findings are consistent with previous research in college samples and suggest the existence of multiple pathways to alcohol and tobacco use and co-use in college students.

Marijuana: respiratory tract effects.

PubMed

Owen, Kelly P; Sutter, Mark E; Albertson, Timothy E

2014-02-01

Marijuana is the most commonly used drug of abuse in the USA. It is commonly abused through inhalation and therefore has effects on the lung that are similar to tobacco smoke, including increased cough, sputum production, hyperinflation, and upper lobe emphysematous changes. However, at this time, it does not appear that marijuana smoke contributes to the development of chronic obstructive pulmonary disease. Marijuana can have multiple physiologic effects such as tachycardia, peripheral vasodilatation, behavioral and emotional changes, and possible prolonged cognitive impairment. The carcinogenic effects of marijuana are unclear at this time. Studies are mixed on the ability of marijuana smoke to increase the risk for head and neck squamous cell carcinoma, lung cancer, prostate cancer, and cervical cancer. Some studies show that marijuana is protective for development of malignancy. Marijuana smoke has been shown to have an inhibitory effect on the immune system. Components of cannabis are under investigation as treatment for autoimmune diseases and malignancy. As marijuana becomes legalized in many states for medical and recreational use, other forms of tetrahydrocannabinol (THC) have been developed, such as food products and beverages. As most research on marijuana at this time has been on whole marijuana smoke, rather than THC, it is difficult to determine if the currently available data is applicable to these newer products.

The marijuana leaves are usually mixed with tobaccos and smoked at amusement places in Taiwan. Recently, for investigation-legal purposes, the police asked if we can identify the marijuana smoke in a KTV stateroom (a private room at the entertainment spot for singing, smoking, alcohol drinking, etc.) without marijuana residues. A personal air-sampler pump fitted with the GC liner-tube packed with Tenax-TA adsorbent was used for air sampling. The GC-adsorbent tube was placed in the GC injector port and desorbed directly, followed by GC-MS analysis for the determination of delta9-tetrahydrocannabinol (delta9-THC) in indoor air. The average desorption efficiency and limit of detection for delta9-THC were 89% and 0.1 microg m(-3), respectively, approximately needing 1.09 mg of marijuana leaves smoked in an unventilated closed room (3.0 m x 2.4 m x 2.7 m) to reach this level. The mean delta9-THC contained in the 15 marijuana plants seized from diverse locations was measured to be 0.32%. The delta9-THC in room air can be successfully identified from mock marijuana cigarettes, mixtures of marijuana and tobacco, and an actual case. The characteristic delta9-THC peak in chromatogram can serve as the indicator of marijuana. Positive result suggests marijuana smoking at the specific scene in the recent past, facilitating the formulation of further investigation.

The purpose of this study was to investigate whether risk factors for cigarette smoking assessed in adolescence predict the use of novel tobacco and nicotine products (hookah, little cigars, and e-cigarettes) in early emerging adulthood. In a longitudinal study (N = 862), risk factors were measured in middle and high school, and novel product use was measured in emerging adulthood (mean age 22.4 years). Structural equation modeling was used to test a model predicting lifetime use of any of hookah, little cigars, and e-cigarettes in early emerging adulthood from distal predictors (gender, maternal smoking through Grade 8; already tried alcohol, cigarettes, or marijuana by Grade 8; and sensation seeking at Grade 8) and potential mediators (intentions to smoke cigarettes, drink alcohol or smoke marijuana at Grade 9, and smoking trajectory across high school). The most prevalent novel tobacco product was hookah (21.7%), followed by little cigars (16.8%) and e-cigarettes (6.6%). Maternal smoking, having already tried substances, and sensation seeking each predicted the use of at least one of these products via an indirect path through intentions to use substances and membership in a high-school smoking trajectory. Risk factors for cigarette smoking were found to predict novel tobacco use, suggesting that interventions to prevent cigarette smoking could be extended to include common novel tobacco products.

Kerr, David C. R.; Tiberio, Stacey S.; Capaldi, Deborah M.

2015-01-01

Objective We studied the extent to which parent marijuana use in adolescence is associated with marijuana use onset in offspring through contextual family and peer risks. Method Fathers assessed (n = 93) since childhood, their 146 offspring (n = 83 girls), and offspring's mothers (n = 85) participated in a longitudinal study. Using discrete-time survival analysis, fathers’ (prospectively measured) and mothers’ (retrospective) adolescent marijuana use was used to predict offspring marijuana use onset through age 19 years. Parental monitoring, child exposure to marijuana use, peer deviance, peer marijuana use, and perceptions of parent disapproval of child use were measured before or concurrent with onset. Results Parents’ adolescent marijuana use was significantly associated with less monitoring, offspring alcohol use, the peer behaviors, exposure to adult marijuana use, and perceptions of less parent disapproval. Male gender and the two peer behaviors were positively associated with children's marijuana use onset, controlling for their alcohol use. Parents’ adolescent marijuana use had a significant indirect effect on child onset through children's deviant peer affiliations and a composite contextual risk score. Conclusions Parents’ histories of marijuana use may contribute indirectly to children's marijuana use onset through their influence on the social environments children encounter; specifically, those characterized by more liberal use norms, exposure to marijuana use and deviant and marijuana-using peers, and less adult supervision. Given that alcohol use onset was controlled, findings suggest that the contextual factors identified here confer unique risk for child marijuana use onset. PMID:26166667

Topical trends in tobacco and alcohol articles published in three dental journals, 1980-2010.

The aim of this study was to conduct a review of articles about tobacco or alcohol published from 1980 to 2010 in the Journal of the American Dental Association (JADA), Journal of Dental Education (JDE), and Journal of Public Health Dentistry (JPHD) in an attempt to identify trends by decade in topics relevant to oral health consequences, oral cancer linkages, and cessation counseling. NVivo qualitative analysis software was used to code abstracts using the keywords "tobacco" or "alcohol." The search identified 269 articles: tobacco=211 (78%), alcohol=58 (22%). This number represented 2.4% of the total articles published in these journals for the specified years. While the percentage of tobacco-related articles increased over this period (with highs in the 1990s of 4.1% in the JDE and 9% in the JPHD), the percentage of alcohol articles reached only 1% for JADA and 3.3% for the JPHD in the 2000s. The number of tobacco-related articles addressing oral health effects, oral cancer linkages, and cessation counseling increased in the 1990s. Although there were modest increases in the number of articles about alcohol-related oral health effects and oral cancer linkages (particularly in the JPHD in the 2000s), only two articles (in JADA in the 2000s) addressed alcohol cessation counseling. This study concluded that tobacco and alcohol have received limited, though increasing, attention in these three major journals between 1980 and 2010, with alcohol receiving less attention than tobacco. These results suggest a need for more published studies on tobacco and alcohol interventions in dental and allied dental education to prepare students to contribute to this aspect of their patients' health.

The aims of this study were to assess the impact of ceremonial use of ayahuasca—a psychedelic brew containing N,N-dimethyltryptamine (DMT) and β-carboline —and attendance at União do Vegetal (UDV) meetings on substance abuse; here we report the findings related to alcohol and tobacco use disorder. A total of 1,947 members of UDV 18+ years old were evaluated in terms of years of membership and ceremonial attendance during the previous 12 months. Participants were recruited from 10 states from all major regions of Brazil. Alcohol and tobacco use was evaluated through questionnaires first developed by the World Health Organization and the Substance Abuse and Mental Health Services Administration. Analyses compared levels of alcohol and tobacco use disorder between the UDV and a national normative sample (n = 7,939). Binomial tests for proportions indicated that lifetime use of alcohol and tobacco was higher in UDV sample compared to the Brazilian norms for age ranges of 25–34 and over 34 years old, but not for the age range of 18–24 years old. However, current use disorders for alcohol and tobacco were significantly lower in the UDV sample than the Brazilian norms. Regression analyses revealed a significant impact of attendance at ayahuasca ceremonies during the previous 12 months and years of UDV membership on the reduction of alcohol and tobacco use disorder.

Medical marijuana legalization is associated with a higher prevalence of marijuana use which may affect cigarette use and nicotine dependence in co-users. In the present study, we examined relationships between statewide legalization of medical marijuana and prevalence of cigarette and marijuana co-use and nicotine dependence in co-using adolescents and adults. Data were analyzed from the 2013 National Survey on Drug Use and Health. We compared cigarette and marijuana co-use in the past 30days across age categories (12-64 years) by statewide medical marijuana legalization. Logistic regression models were used to estimate the odds of having nicotine dependence among current cigarette smokers who also reported past 30-day marijuana use and "ever but not current" marijuana use (vs. "never" use) adjusting for covariates including statewide legalization of medical marijuana. Overall, 5.1% of the sample reported past 30-day cigarette and marijuana co-use and a higher proportion of co-users resided in states where medical marijuana was legal compared to illegal (5.8% vs. 4.8%; p=0.0011). Co-use was associated with greater odds of having nicotine dependence compared to cigarette-only use across age categories. Odds were highest and up to 3-times higher in adolescents aged 12-17 years (OR=3.54; 95%CI: 1.81-6.92) and adults aged 50-64 years (OR=3.08; CI: 1.45-6.55). Marijuana policy could inadvertently affect cigarette and marijuana co-use and pose challenges to tobacco cessation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Vested Interests in addiction research and policy. Alliance between tobacco and alcohol industries to shape public policy.

PubMed

Jiang, Nan; Ling, Pamela

2013-05-01

The tobacco and alcohol industries share common policy goals when facing regulation, opposing policies such as tax increases and advertising restrictions. The collaboration between these two industries in the tobacco policy arena is unknown. This study explored if tobacco and alcohol companies built alliances to influence tobacco legislation and, if so, how those alliances worked. Analysis of previously secret tobacco industry documents. In the early 1980s, tobacco companies started efforts to build coalitions with alcohol and other industries to oppose cigarette excise taxes, clean indoor air policies and tobacco advertising and promotion constraints. Alcohol companies were often identified as a key partner and source of financial support for the coalitions. These coalitions had variable success interfering with tobacco control policy-making. The combined resources of tobacco and alcohol companies may have affected tobacco control legislation. These alliances helped to create the perception that there is a broader base of opposition to tobacco control. Advocates should be aware of the covert alliances between tobacco, alcohol and other industries and expose them to correct this misperception. © 2013 Society for the Study of Addiction.

To examine how saturation of an adolescent's environment with models of cigarette smoking (e.g., parents, siblings, friends) affects the probability of tobacco and alcohol use among junior high and high school students. The Health and Smoking Questionnaire was administered to 806 adolescents (182 smokers and 624 nonsmokers; 57.2% female) average age of 15.1 years (SD = 1.6) in a mid-size Midwestern town. The questionnaire contains standardized items in five domains: demographics, smoking status and history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style. Risk for smoking or using alcohol increased dramatically as the number of models who smoke increased in an adolescent's environment. For instance, adolescents with one significant other who smoked were nearly four times (OR = 3.76, p <.001) more likely to smoke than someone with no significant others who smoked. However, if an adolescent had four significant others who smoked, they were over 160 times more likely to smoke (OR = 161.25, p <.001). Similar results were found for alcohol use; adolescents who had one significant other who smoked were more than 2.5 (OR = 2.66, p <.001) times more likely to drink than those without smoking models. Adolescents who had four significant other smoking models were 13 times (OR = 13.08, p <.001) more likely to drink. As the number of cigarette smokers in an adolescent's environment increases, risk of tobacco and alcohol use increases substantially. These data suggest that multiple models of tobacco use will substantially increase risk for substance use in adolescents.

A vast majority of people who abuse alcohol are also defined as "heavy smokers". Tobacco smokes induces CYP1A1, CYP1A2, CYP2A6 isoenzymes, but on the other hand, ethanol activates CYP2E1, which can be important during combined, chronic use of both of them. The aim of the study was to evaluate the influence of tobacco smoke xenobiotics on ethanol pharmacokinetics and the level of its metabolites in alcohol preferring and non-preferring rats. Ethanol, acetaldehyde, methanol, n-propanol and n-butanol were determined in whole blood by means of gas chromatography. Cotinine in serum was determined by LC-MS/MS. A non-compartmental analysis (cotinine, acetaldehyde) and Widmark equation (ethanol) were used for pharmacokinetic parameters calculation. Ethanol levels were lower in animals exposed to tobacco smoke compared to rats receiving this xenobiotic, without a prior exposure to tobacco smoke. Lower values of the studied pharmacokinetic parameters were observed in the alcohol preferring males compared to the non-alcohol preferring rats. Both n-propanol and n-butanol had higher values of the pharmacokinetic parameters analyzed in the animals exposed to tobacco smoke and ethanol compared to those, which ethanol was administered only once. An increase in maximum concentration and the area under concentration-time curve for ethanol after its administration to rats preferring alcohol and exposed to tobacco smoke are accompanied by a decrease in the volume of distribution. The changes in the volume of distribution may be caused by an increase in the first-pass effect, in the intestinal tract and/or in the liver. The acetaldehyde elimination rate constant was significantly higher in alcohol-preferring animals. Copyright © 2015 Institute of Pharmacology, Polish Academy of Sciences.

1997-01-01

OBJECTIVES: Music videos from five genres of music were analyzed for portrayals of tobacco and alcohol use and for portrayals of such behaviors in conjunction with sexuality. METHODS: Music videos (n = 518) were recorded during randomly selected days and times from four television networks. Four female and four male observers aged 17 to 24 years were trained to use a standardized content analysis instrument. All videos were observed by rotating two-person, male-female teams who were required to reach agreement on each behavior that was scored. Music genre and network differences in behaviors were analyzed with chi-squared tests. RESULTS: A higher percentage (25.7%) of MTV videos than other network videos portrayed tobacco use. The percentage of videos showing alcohol use was similar on all four networks. In videos that portrayed tobacco and alcohol use, the lead performer was most often the one smoking or drinking and the use of alcohol was associated with a high degree of sexuality on all the videos. CONCLUSIONS: These data indicate that even modest levels of viewing may result in substantial exposure to glamorized depictions of alcohol and tobacco use and alcohol use coupled with sexuality.

Previous studies have examined what adolescents find appealing in tobacco and alcohol advertisements and how different themes in advertisements are used to manipulate consumer behaviors. Yet, we know little about the relationship between the themes portrayed in advertisements and youth attitudes towards those themes. This study compared attitudes towards advertisements for different consumer products in a sample of urban and rural adolescent boys in order to examine how key marketing themes impact adolescent attitudes towards those advertisements. Participants were 11- to 16-year-old boys (N = 1220) residing in either urban or rural Ohio Appalachian counties. Each participant viewed five print advertisements (one each for cigarettes, electronic cigarettes (e-cigarettes), smokeless tobacco (SLT), non-alcoholic beverages, and alcohol), presented in a random order, for eight seconds each. All advertisements had appeared in magazines that adolescent males commonly read. Attitudes towards each of the five advertisements were assessed. The advertisements were then coded for the presence of various themes, including social acceptance and masculinity. Analyses were conducted to determine associations between advertisement type and the attitude measure, and between the presence of a theme and the attitude measure. Overall, participants preferred non-tobacco advertisements to tobacco advertisements, rural participants had less positive attitudes and participants who had peers who used tobacco had more positive attitudes. Social acceptance and entertainment themes increased the appeal of SLT advertisements, and sex appeal increased the appeal of e-cigarette advertisements. Conclusions/Importance: Findings suggest that advertisements that promote the social nature of use in SLT advertisements may be of particular concern for their influence on adolescent boys.

To inform policy debates surrounding marijuana decriminalization and add to our understanding of social and structural influences on youth drug use, we sought to determine whether there was an independent association between neighborhood drug prevalence and individual-level marijuana use after controlling for peer drug and alcohol norms. We analyzed cross-sectional data from a household survey of 563 youth aged 15-24 in Baltimore, Maryland. The study population was 88 % African-American. Using gender-stratified, weighted, multilevel logistic regression, we tested whether neighborhood drug prevalence was associated with individual-level marijuana use after controlling for peer drug and alcohol norms. Bivariate analyses identified a significant association between high neighborhood drug prevalence and marijuana use among female youth (AOR = 1.76, 95% CI = 1.26, 2.47); the association was in a similar direction but not significant among male youth (AOR = 1.26, 95% CI = 0.85, 1.87). In multivariable regression controlling for peer drug and alcohol norms, high neighborhood drug prevalence remained significantly associated among female youth (AOR = 1.59, 95% CI = 1.12, 2.27). Among male youth, the association was attenuated toward the null (AOR = 0.95, 95% CI = 0.63, 1.45). In the multivariable model, peer drug and alcohol norms were significantly associated with individual-level marijuana use among female youth (AOR = 1.54, 95% CI = 1.17, 2.04) and male youth (AOR = 2.59, 95% CI = 1.65, 4.07). This work suggests that individual-level marijuana use among female youth is associated with neighborhood drug prevalence independent of peer norms. This finding may have important implications as the policy landscape around marijuana use changes.

What Did You Expect?: The Interaction Between Cigarette and Blunt vs. Non-Blunt Marijuana Use among African American Young Adults

Ramo, Danielle

2017-01-01

Background Marijuana and tobacco co-use is highly prevalent among African American young adults. In an effort to inform prevention and treatment interventions, the current study examined the expectancies around the co-use of marijuana and cigarettes among African American young adults. Methods An anonymous online survey recruited African American adults (N = 111) age 18 to 29 who reported past-month marijuana and cigarette co-use. Participants completed the 14-item Nicotine and Marijuana Interaction Expectancy (NAMIE) Questionnaire, with three scales: (1) marijuana use increases tobacco use and urges, (2) tobacco use increases marijuana use and urges and (3) smoking to cope with marijuana urges. Participants also answered questions about marijuana and tobacco initiation and use. Analyses were conducted separately for blunt co-users (i.e., blunt and cigarette use) and non-blunt co-users (i.e., non-blunt marijuana and cigarette use). Results A majority of co-users (66%) used blunts as a form of co-use. Non-blunt co-users had higher expectancy scores on NAMIE scales 2 and 3 than blunt co-users. However, only blunt co-users showed a positive association between severity of marijuana use and NAMIE scales 2 (p <.01) and 3 (p <.01). Conclusions Findings provide further evidence for the use of the NAMIE and suggest a need to assess and address expectations regarding marijuana and tobacco co-use in prevention and treatment interventions, especially among young African American adults who co-use blunts and cigarettes.

Recent changes in policy and social norms related to marijuana use have increased its use and concern about how/where marijuana should be used. We aimed to characterize rules regarding marijuana and its use in homes. We recruited 1,567 US adults aged 18-34 years through Facebook advertisements to complete an online survey assessing marijuana use, social factors, perceptions of marijuana, and rules regarding marijuana and its use in the home, targeting tobacco and marijuana users to ensure the relevance of this topic. Overall, 648 (41.6%) were current marijuana users; 46.0% of participants reported that "marijuana of any type is not allowed in their home or on their property." Of those allowing marijuana on their property, 6.4% prohibited use of marijuana in their home. Of the remainder, 29.2% prohibited smoking marijuana, and 11.0% prohibited vaping, eating, or drinking marijuana. Correlates of more restrictive rules included younger age, being female, having marijuana, perceiving use to be less socially acceptable and more harmful, and being a nonuser (p's <.05). Attitudes and subjective norms regarding marijuana are correlates of allowing marijuana in residential settings. Future work should examine areas of risk regarding household marijuana rules.

Background There is little information about pregnancy-related changes in alcohol use and factors contributing to changes among women with unwanted pregnancies. This study describes changes in alcohol use from before pregnancy recognition to during pregnancy and identifies important predictors of alcohol use severity among women with unwanted pregnancies. Methods Data are from the Turnaway Study of 956 women seeking pregnancy termination at 30 U.S. facilities between 2008 and 2010, some of whom were denied care because they were past the gestational limit of the facility where they were recruited and were still pregnant at the baseline interview, one week after termination-seeking. Predictors of alcohol use severity (a latent variable) were identified. Results 56% of the total sample reported any alcohol use the month before pregnancy recognition, with 23% reporting six or more drinks on an occasion. Among the total sample, 35% of those drinking before pregnancy recognition had quit and 20% had reduced one week after termination seeking. Among those denied terminations and still pregnant, 71% had quit and 14% had reduced. In a multivariate model predicting alcohol severity, younger age, still pregnant, one or more previous births, later gestation, childhood physical abuse, and marijuana and other drug use were associated with lower severity; having completed college, tobacco use, and recent physical violence were associated with higher severity. Conclusions The proportion of the total sample drinking before pregnancy recognition is similar to national samples of women of childbearing age while the proportion binge drinking appears higher. Of women denied terminations who were still pregnant, the proportion having quit is similar to other populations of pregnant women. More research is needed to examine whether pregnant women may be substituting alcohol for marijuana and other drugs. Interventions focusing on alcohol use severity during pregnancy may need to also

Masters, Matthew N; Haardörfer, Regine; Windle, Michael; Berg, Carla

2018-02-01

Limited research has examined psychosocial factors that differ among cigarette users, marijuana users, and co-users and influence their cessation efforts. We examined: 1) sociodemographic, mental health, and other substance use in relation to user category; and 2) associations among these factors in relation to recent quit attempts and readiness to quit among single product versus co-users. We used a cross-sectional design to study college students aged 18-25 from seven Georgia campuses, focusing on the 721 reporting cigarette and/or marijuana use in the past 4months (238 cigarette-only; 331 marijuana-only; 152 co-users). Multinomial logistic regression showed that correlates (p's<0.05) of cigarette-only versus co-use included attending public or technical colleges (vs. private) and not using little cigars/cigarillos (LCCs), e-cigarettes, and alcohol. Correlates of marijuana-only versus co-use included being Black or Hispanic (vs. White), not attending technical school, and not using LCCs and e-cigarettes. Importance was rated higher for quitting cigarettes versus marijuana, but confidence was rated lower for quitting cigarettes versus marijuana (p's<0.001). Co-users were more likely to report readiness to quit and quit attempts of cigarettes versus marijuana (p's<0.001). While 23.26% of marijuana-only and 15.13% of cigarette-only users reported readiness to quit, 41.18% of cigarette-only and 21.75% of marijuana-only users reported recent quit attempts (p's<0.001). Binary logistic regressions indicated distinct correlates of readiness to quit and quit attempts of cigarettes and marijuana. Cessation efforts of the respective products must attend to co-use with the other product to better understand relative perceptions of importance and confidence in quitting and actual cessation efforts.

AIM To determine the prevalence of drug and substance abuse among high school students in Jalisco and its association with the severity of health, behavior and psychosocial problems in order to provide evidence for possible prevention and treatment needs. METHODS A multi-stage random sample of Jalisco high school students was given a paper-and-pencil survey based upon an adapted version of the drug use screening inventory (DUSI) (n = 24699; n = 2832). The DUSI showed adequate psychometric characteristics in this population. The statistical analyses accommodated the complex survey design with attention to unequal probability of selection and clustering of participants within schools and regions. RESULTS An estimated 44% of the students had smoked tobacco, one in five students was a current smoker, and one in four students used to smoke but had not smoked for one year or more. By contrast, 6.8% of the students reported having used marijuana, cocaine, or both. Behavioral problems, deviant peer affiliation, and troubled families were independently associated with drug use. One in two students who used tobacco or alcohol had used these drugs in the past year (46% and 54%, respectively), and one in four students who used marijuana or cocaine in their lifetime had used those drugs in the past year (28% in both cases). CONCLUSION The rates of cocaine use as well as the proportion of current users were higher than expected among high school students and indicate changing patterns of drug use in Mexico. These results corroborate that the general trend of drug use by youth in Mexico is increasing. Results from this study help us better understand the needs of at-risk youth and the need for new treatment and prevention strategies. PMID:29568730

This comprehensive study focuses exclusively on adult Arabs in Israel and is aimed at examining tobacco and alcohol use rates and their predictors. One thousand and two hundred Arab adults were randomly sampled via cluster sampling and interviewed using a structured questionnaire. Forty-four per cent of respondents reported tobacco use while 39% reported alcohol use. There were notable gender gaps in use, as well as differences between Muslims and Christians. Odds of using both tobacco and alcohol increased with having a greater tendency towards risk-taking and more time spent partying. Odds of alcohol use also increased with having positive attitudes towards use, lower perceived risk and greater intention to use. These findings add a more complete understanding to the phenomenon of tobacco and alcohol use among Arab adults in Israel and carry important implications for future research and practice. © 2014 Australasian Professional Society on Alcohol and other Drugs.

Alcohol and tobacco advertising in black and general audience newspapers: targeting with message cues?

Cohen, Elisia L; Caburnay, Charlene A; Rodgers, Shelly

2011-07-01

This study content analyzed 928 tobacco- and alcohol-related advertisements from a 3-year national sample of Black (n = 24) and general audience (n = 11) newspapers from 24 U.S. cities. The authors compared the frequency of tobacco and alcohol product and control advertising in Black versus general audience newspapers, as well as the presence of 5 message cues: model ethnicity, presence of health official, referral to resources, personal behavior mobilization, and localization. Results within health issues show that Black newspapers had more alcohol product advertising than did general audience newspapers. In contrast, Black newspapers had less alcohol and tobacco control advertising than general audience newspapers. Black newspapers' tobacco/alcohol product advertisements had more African American models than did general audience newspapers' tobacco/alcohol advertising, whereas general audience newspapers' tobacco control advertisements were significantly more likely to feature public health officials than ads in Black newspapers. Fewer message cues such as personal behavior mobilization, referral to resources, and localization were present in Black versus general audience newspapers. Results suggest that Black newspapers may have greater dependency than do general audience newspapers on these risk-related advertisements that target African American consumers. Given the current advertising environment, public health initiatives are needed to counter unhealthy alcohol product advertising messages that target vulnerable populations.

The Economic Geography of Medical Marijuana Dispensaries in California

Morrison, Chris; Gruenewald, Paul J.; Freisthler, Bridget; Ponicki, William R.; Remer, Lillian G.

2014-01-01

Background The introduction of laws that permit the use of marijuana for medical purposes has led to the emergence of a medical marijuana industry in some US states. This study assessed the spatial distribution of medical marijuana dispensaries according to estimated marijuana demand, socioeconomic indicators, alcohol outlets and other socio-demographic factors. Method Telephone survey data from 5,940 residents of 39 California cities were used to estimate social and demographic correlates of marijuana demand. These individual-level estimates were then used to calculate aggregate marijuana demand (i.e. market potential) for 7,538 census block groups. Locations of actively operating marijuana dispensaries were then related to the measure of demand and the socio-demographic characteristics of census block groups using multilevel Bayesian conditional autoregressive logit models. Results Marijuana dispensaries were located in block groups with greater marijuana demand, higher rates of poverty, alcohol outlets, and in areas just outside city boundaries. For the sampled block groups, a 10% increase in demand within a block group was associated with 2.4% greater likelihood of having a dispensary, and a 10% increase in the city-wide demand was associated with a 6.7% greater likelihood of having a dispensary. Conclusion High demand for marijuana within individual block groups and within cities is related to the location of marijuana dispensaries at a block-group level. The relationship to low income, alcohol outlets and unincorporated areas indicates that dispensaries may open in areas that lack the resources to resist their establishment. PMID:24439710

Characterizing substance use and mental health profiles of cigar, blunt, and non-blunt marijuana users from the National Survey of Drug Use and Health.

PubMed

Cohn, Amy; Johnson, Amanda; Ehlke, Sarah; Villanti, Andrea C

2016-03-01

Smoking marijuana in a cigar (blunt use) is gaining popularity in the U.S. Research suggests that blunt users differ from exclusive cigar or marijuana users on a variety of demographic and substance use factors. Misreporting of blunts and cigars is also common, particularly among young people, and may lead to inaccurate prevalence estimates. To determine subtype differences, this study investigated the prevalence and demographic, mental health, and substance use correlates of four mutually-exclusive groups of blunt, cigar, and marijuana past 30-day users (cigar-only, blunt-only, non-blunt marijuana, or dual cigar-blunt). Data were analyzed from the 2013 National Survey of Drug Use and Health. In weighted multinomial logistic regression models, respondents who were younger, Black, and who had used tobacco, alcohol, or other drugs in the past 30-days had the highest odds of reporting blunt-only or dual cigar-blunt use. Those reporting blunt-only and dual cigar-blunt use also endorsed a greater number of marijuana and alcohol use disorder symptoms compared to those reporting cigar-only and non-blunt marijuana use. Lower marijuana risk perceptions were associated with increased odds of marijuana use with or without blunts. Major depressive episode was uniquely associated with non-blunt marijuana use. With respect to misclassifiers, respondents who reported past 30-day blunt use but not past 30-day marijuana use were younger, Black, female, and had lower education and income. Those who report blunt-only and dual cigar-blunt use showed the most severe risk profiles. Communicating health consequences and risks of blunt use should be directed toward specific subgroups.

Pedersen, Eric R; Hummer, Justin F; Rinker, Dipali Venkataraman; Traylor, Zach K; Neighbors, Clayton

2016-05-01

Marijuana use can result in a variety of negative consequences, yet it remains popular among young adults and the general public at large. Combined with the growing empirical support for the benefits of medicinal marijuana as well as the steady increase in popular opinion regarding its legalization, it is of growing importance to identify strategies that may mitigate the harms related to marijuana use, reduce consumption levels, and limit resulting negative consequences among young adults who use marijuana. The purpose of this study was to develop and conduct initial psychometric analyses on a new scale, which we named the Protective Behavioral Strategies for Marijuana (PBSM) scale. A sample of undergraduate college students who reported past-6-month marijuana use (n = 210) responded to the initial pool of PBSM items and completed measures of marijuana use, consequences from marijuana use, alcohol use, and protective behavioral strategies for alcohol. Results from an iterative principal component analyses process yielded a single-factor structure with 39 items. The PBSM mean composite score negatively associated with marijuana use and consequences, with the strongest correlations evident for pastmonth users. The PBSM also significantly positively correlated with alcohol protective strategies. Protective behavioral strategies for marijuana appear to be a measurable construct that are related to marijuana frequency and consequences, and thus may be a useful component of intervention and prevention programs with young adults. More work testing the PBSM items with larger and more diverse samples of young adults is encouraged.

Health risks of including alcohol and tobacco in PICTA free trade.

PubMed

Hill, Linda

2004-03-01

In April 2005 Pacific Forum leaders will decide whether to include alcohol and tobacco in the Pacific Island Countries Trade Agreement (PICTA). This article presents arguments for keeping alcohol out of regional free trade agreements. Inclusion will allow regional rationalisation of production, increased alcohol availability, competition and marketing, and lower prices. These trade goals are inappropriate for alcohol and tobacco. Pacific public health organisations are concerned that official advice has focused on fiscal impacts, not health and social impacts. The World Health Organization has identified alcohol as the leading factor in injury and disease for low-mortality developing countries. Effective policies to reduce alcohol related harm include restrictions on availability, as well as excise taxes affecting price. Under trade agreements elsewhere, national alcohol policies have been challenged as 'non-tariff barriers to trade'. Hazardous drinking is of increasingly concern in the Pacific and decisions about alcohol should not reflect commercial interests.

Whereas detrimental effects of alcohol on increased sexual risk have been documented in event-level and laboratory studies, less is known about the combined use of alcohol and marijuana and their relative impact on sexual risk behavior. We examined the degree to which both heavy drinking and marijuana use were associated with condomless sexual intercourse with casual versus main partners in a sample of weekly marijuana smokers. Method: Participants reported substance use and sexual activity using a 60-day Timeline Followback interview method (n = 112). Results: Results of generalized estimating equations indicated that both alcohol and marijuana use were independently associated with greater odds of having sexual intercourse but were not associated with greater odds of unprotected sex with a casual partner. Heavy drinking on a given day was associated with increased odds of having casual protected sex. Using both substances synergistically increased the likelihood of unprotected sex with a main partner. Conclusions: Findings suggest that behaviors posing higher sexual risk (condomless intercourse or sex with casual partners) occur on days when alcohol use exceeds moderate drinking guidelines. Interventions designed to reduce sexual risk behaviors may need to specifically target heavy drinking alone or when used with marijuana. PMID:26751360

The objective of this study was to use volumetric MRI to study brain volumes in 10- to 14-year-old children with and without intrauterine exposure to cocaine, alcohol, cigarettes, or marijuana. Volumetric MRI was performed on 35 children (mean age: 12.3 years; 14 with intrauterine exposure to cocaine, 21 with no intrauterine exposure to cocaine) to determine the effect of prenatal drug exposure on volumes of cortical gray matter; white matter; subcortical gray matter; cerebrospinal fluid; and total parenchymal volume. Head circumference was also obtained. Analyses of each individual substance were adjusted for demographic characteristics and the remaining 3 prenatal substance exposures. Regression analyses adjusted for demographic characteristics showed that children with intrauterine exposure to cocaine had lower mean cortical gray matter and total parenchymal volumes and smaller mean head circumference than comparison children. After adjustment for other prenatal exposures, these volumes remained smaller but lost statistical significance. Similar analyses conducted for prenatal ethanol exposure adjusted for demographics showed significant reduction in mean cortical gray matter; total parenchymal volumes; and head circumference, which remained smaller but lost statistical significance after adjustment for the remaining 3 exposures. Notably, prenatal cigarette exposure was associated with significant reductions in cortical gray matter and total parenchymal volumes and head circumference after adjustment for demographics that retained marginal significance after adjustment for the other 3 exposures. Finally, as the number of exposures to prenatal substances grew, cortical gray matter and total parenchymal volumes and head circumference declined significantly with smallest measures found among children exposed to all 4. CONCLUSIONS; These data suggest that intrauterine exposures to cocaine, alcohol, and cigarettes are individually related to reduced head

Understanding the relationship between health insurance coverage and tobacco and alcohol use among reproductive age women can provide important insight into the role of access to care in preventing tobacco and alcohol use among pregnant women and women planning to become pregnant. We examined the association between health insurance coverage and both past month alcohol use and past month tobacco use in a nationally representative sample of women age 12-44 years old, by pregnancy status. The women (n=97,788) were participants in the National Survey of Drug Use and Health (NSDUH) in 2010-2013. Logistic regression models assessed the association between health insurance (insured versus uninsured), past month tobacco and alcohol use, and whether this was modified by pregnancy status. Pregnancy status significantly moderated the relationship between health insurance and tobacco use (p-value≤0.01) and alcohol use (p-value≤0.01). Among pregnant women, being insured was associated with lower odds of alcohol use (adjusted odds ratio [AOR]=0.47; 95% confidence interval [CI]=0.27-0.82), but not associated with tobacco use (AOR=1.14; 95% CI=0.73-1.76). Among non-pregnant women, being insured was associated with lower odds of tobacco use (AOR=0.67; 95% CI=0.63-0.72), but higher odds of alcohol use (AOR=1.23; 95% CI=1.15-1.32). Access to health care, via health insurance coverage is a promising method to help reduce alcohol use during pregnancy. However, despite health insurance coverage, tobacco use persists during pregnancy, suggesting missed opportunities for prevention during prenatal visits. Copyright © 2016 Elsevier Ireland Ltd.

We sought to examine relationships between physician advice and use of tobacco and alcohol during pregnancy among 683 women in the upper Midwest. Data on risk of substance use during pregnancy were analyzed using logistic regression analysis. A higher proportion of women used tobacco (34%) than alcohol (25%) during their most recent pregnancy. Women who received advice from a physician to abstain from alcohol reported a lower risk of smoking and drinking during pregnancy than women who did not receive such advice. Risk of smoking and drinking during pregnancy was also common among women who reported early onset of alcohol use. Results suggest that physician advice regarding alcohol use during pregnancy is protective against maternal smoking and drinking during pregnancy.

To quantify the association between gender role orientation and tobacco and alcohol use among young people of the State of Morelos. Study conducted in 2004-2005, students aged 14 to 24 years (n = 1 730). Sociodemographic variables (area of residence, socioeconomic status), family (parental education and violence), psycho-sociological (gender role, self-esteem, depression, alcohol consumption, tobacco, locus of control, sexual abuse). Logistic regression analysis. Factors associated with use of tobacco: In women, being androgynous undesirable, masculine role, attempted sexual abuse and urban areas. For men, depression and submission. Factors associated with alcohol use: In women, masculine gender role; and in men to be older than 20 years, living in semi-urban and urban area, and internal locus. The machismo is one of the gender role orientations with greater association with the use of tobacco primarily in girls in Mexico, and the masculine or instrumental role with alcohol.

Urban populations disproportionately experience poor sexual outcomes, including high rates of teenage pregnancy and sexually transmitted infections. However, the contribution of substance use across adolescence to poor sexual outcomes in young adulthood has not been investigated in depth, despite offering opportunities for more targeted prevention. This study aimed to estimate joint trajectories of adolescent alcohol and marijuana use to determine if they relate differently to four sexual outcomes: multiple sexual partners, sex without a condom, teenage pregnancy, and contraction of a sexually transmitted infection in young adulthood (by age 25). Data came from a longitudinal study of urban youth followed from age 6 to age 25, with annual assessments during adolescence and young adulthood (n = 608). The sample showed high levels of sexual risk, with young adults on average having sex without a condom once in the past month, 28.5% having multiple sexual partners in the past month, one quarter having contracted a sexually transmitted infection, and over 60% of the women being pregnant as a teenager and 36% of the men having gotten a partner pregnant. Applying longitudinal latent profile analysis to estimate joint trajectories of alcohol and marijuana use from grades 8-12, we identified four classes representing high dual use, moderate alcohol use, moderate alcohol use with increasing marijuana use, and non-use. Class membership differently predicted all four outcomes investigated with high dual users having the highest level of teenage pregnancy and the increasing marijuana trajectory having the highest risk of engaging with multiple sexual partners in the past month. Results suggest implications for both sexual risk and substance use prevention for urban youth.

OBJECTIVE To analyze temporal trends of the prevalence of alcohol and tobacco use among Brazilian students. METHODS We analyzed data published between 1989 and 2010 from five epidemiological surveys on students from the 6th to the 12th grade of public schools from the ten largest state capitals of Brazil. The total sample consisted of 104,104 students and data were collected in classrooms. The same collection tool – a World Health Organization self-reporting questionnaire – and sampling and weighting procedures were used in the five surveys. The Chi-square test for trend was used to compare the prevalence from different years. RESULTS The prevalence of alcohol and tobacco use varied among the years and cities studied. Alcohol consumption decreased in the 10 state capitals (p < 0.001) throughout 21 years. Tobacco use also decreased significantly in eight cities (p < 0.001). The highest prevalence of alcohol use was found in the Southeast region in 1993 (72.8%, in Belo Horizonte) and the lowest one in Belem (30.6%) in 2010. The highest past-year prevalence of tobacco use was found in the South region in 1997 (28.0%, in Curitiba) and the lowest one in the Southeast in 2010 (7.8%, in Sao Paulo). CONCLUSIONS The decreasing trend in the prevalence of tobacco and alcohol use among students detected all over the Country can be related to the successful and comprehensive Brazilian antitobacco and antialcohol policies. Despite these results, the past-year prevalence of alcohol consumption in the past year remained high in all Brazilian regions. PMID:26465662

Background Marijuana is the most frequently used illicit substance in the United States. Little is known of the role that macro-level factors, including community norms and laws related to substance use, play in determining marijuana use, abuse and dependence. We tested the relationship between state-level legalization of medical marijuana and marijuana use, abuse, and dependence. Methods We used the second wave of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a national survey of adults aged 18+ (n=34,653). Selected analyses were replicated using the National Survey on Drug Use and Health (NSDUH), a yearly survey of ~68,000 individuals aged 12+. We measured past-year cannabis use and DSM-IV abuse/dependence. Results In NESARC, residents of states with medical marijuana laws had higher odds of marijuana use (OR: 1.92; 95% CI: 1.49-2.47) and marijuana abuse/dependence (OR: 1.81; 95% CI: 1.22-2.67) than residents of states without such laws. Marijuana abuse/dependence was not more prevalent among marijuana users in these states (OR: 1.03; 95% CI: 0.67-1.60), suggesting that the higher risk for marijuana abuse/dependence in these states was accounted for by higher rates of use. In NSDUH, states that legalized medical marijuana also had higher rates of marijuana use. Conclusions States that legalized medical marijuana had higher rates of marijuana use. Future research needs to examine whether the association is causal, or is due to an underlying common cause, such as community norms supportive of the legalization of medical marijuana and of marijuana use.

Smoking is the preferred method of administration for two of the most frequently abused drugs, marijuana and nicotine. The high temporal and spatial resolution of functional magnetic resonance imaging (fMRI) make it a natural choice for studying the neurobiological effects of smoked drugs if the challenges of smoking in a magnetic resonance (MR) scanner can be overcome. We report on a design for an MR-compatible smoking device that can be used for smoking marijuana (or tobacco) during fMRI examinations. Nine volunteers smoked marijuana cigarettes (3.51% Delta9-THC) on two occasions: with and without the device. The device allowed subjects to smoke while they lay in the scanner, while containing all smoke and odors. Plasma Delta9-THC, subjective reports of intoxication, and heart rate increases are reported, and were all similar in individuals smoking marijuana either with or without the device. The use of this device will help advance research studies on smoked drugs including marijuana, tobacco and crack cocaine.

Use of drugs and alcohol, including tobacco, is linked to adolescent emotional psychopathology. Given that tobacco use is becoming less common over recent years, its co-use with drugs/alcohol may mark a more severe profile of emotional symptomatology. However, it is unclear whether teens with a lifetime history of using drug/alcohol and tobacco exhibit additional elevations in emotional psychopathology and/or multiple forms of emotional psychopathology compared to teens with lifetime drug/alcohol use without comorbid tobacco use. This cross-sectional study compared emotional disorder symptoms and emotional vulnerability traits among adolescents with varying histories of substance use. Ninth-grade students enrolled at two schools in Los Angeles, California, were recruited; 575 met eligibility criteria and provided both student assent and parental consent. Students completed self-report measures of emotional pathology, transdiagnostic, and lifetime substance use. Participants were classified into three groupings: (a) no history of substance use (n = 294); (b) lifetime history of drug/alcohol use without tobacco use (n = 166); and (c) lifetime history of drug/alcohol use with concomitant tobacco use (n = 115). Chi-square results showed that teens with lifetime alcohol/drug use with (vs. without) comorbid tobacco use were more likely to have used 10 of 16 substances assessed in the study. Post-ANOVA pairwise tests revealed that, compared to students with no history of substance use, those with any history of use (alcohol/drugs with and without tobacco use) had higher major depression symptoms and negative affect. Those with lifetime alcohol/drug use with comorbid tobacco use had higher generalized anxiety symptoms and distress, and those with lifetime alcohol/drug use without comorbid tobacco use had higher panic disorder symptoms and anhedonia. There were no significant differences between adolescents with lifetime drug/alcohol use with comorbid tobacco use versus

Marijuana smoke contains many of the same constituents as tobacco smoke, but whether it has similar adverse effects on pulmonary function is unclear. To analyze associations between marijuana (both current and lifetime exposure) and pulmonary function. The Coronary Artery Risk Development in Young Adults (CARDIA) study, a longitudinal study collecting repeated measurements of pulmonary function and smoking over 20 years (March 26, 1985-August 19, 2006) in a cohort of 5115 men and women in 4 US cities. Mixed linear modeling was used to account for individual age-based trajectories of pulmonary function and other covariates including tobacco use, which was analyzed in parallel as a positive control. Lifetime exposure to marijuana joints was expressed in joint-years, with 1 joint-year of exposure equivalent to smoking 365 joints or filled pipe bowls. Forced expiratory volume in the first second of expiration (FEV(1)) and forced vital capacity (FVC). Marijuana exposure was nearly as common as tobacco exposure but was mostly light (median, 2-3 episodes per month). Tobacco exposure, both current and lifetime, was linearly associated with lower FEV(1) and FVC. In contrast, the association between marijuana exposure and pulmonary function was nonlinear (P < .001): at low levels of exposure, FEV(1) increased by 13 mL/joint-year (95% CI, 6.4 to 20; P < .001) and FVC by 20 mL/joint-year (95% CI, 12 to 27; P < .001), but at higher levels of exposure, these associations leveled or even reversed. The slope for FEV(1) was -2.2 mL/joint-year (95% CI, -4.6 to 0.3; P = .08) at more than 10 joint-years and -3.2 mL per marijuana smoking episode/mo (95% CI, -5.8 to -0.6; P = .02) at more than 20 episodes/mo. With very heavy marijuana use, the net association with FEV(1) was not significantly different from baseline, and the net association with FVC remained significantly greater than baseline (eg, at 20 joint-years, 76 mL [95% CI, 34 to 117]; P < .001).

Marijuana is the most widely usedillegal drug in the world, with a prevalence of 2.5%-5%, and the second most commonly smoked substance after tobacco. The components of smoke from combustion of marijuana are similar to those produced by the combustion of tobacco, but they differ in terms of psychoactive components and use. Inhalation of cannabis smoke affects the respiratory tract, so the available evidence must be updated in order to provide pulmonologists with the latest scientific information. In this article, we review the impact of cannabis consumption on the lungs, taking into account that the respiratory route is the most popular route of cannabis consumption. Copyright © 2017 SEPAR.

2014-01-01

The study aimed to investigate (a) the association between low to moderate prenatal alcohol exposure (PAE) and the use of alcohol, tobacco and illicit drugs in adolescence and (b) whether the associations are modified by gender and ethnicity. The subjects of the study were 5922 children and adolescents, aged from 11 to 17 years, enrolled in the cross-sectional German Health Interview and Examination Survey for Children and Adolescents (the KiGGS study). Information on PAE is based on parental self-report questionnaires. Use of alcohol, tobacco and illicit drugs was assessed through self-report questionnaires for adolescents. Low to moderate PAE was associated with an increased risk of drinking alcohol (adjusted odds ratio (OR) 1.73, 95% confidence interval (CI) 1.34, 2.18) and also of illicit drug use (adjusted OR 1.62, 95% CI 1.23, 2.14). The associations between PAE and the use of alcohol, tobacco and illicit drugs differed according to gender and ethnicity. Gender-stratified analyses resulted in adverse effects of PAE on drinking alcohol, smoking and illicit drug use in females; however, in German males, the associations disappeared. Stronger associations between PAE and the outcome measures were found in non-Germans. Our findings indicate that low to moderate levels of maternal alcohol intake during pregnancy are a risk factor for use of alcohol, tobacco and illicit drugs by the offspring, with stronger associations in females and non-Germans.

Out-of-School Time and Adolescent Substance Use.

Lee, Kenneth T H; Vandell, Deborah Lowe

High levels of adolescent substance use are linked to lower academic achievement, reduced schooling, and delinquency. We assess four types of out-of-school time (OST) contexts--unsupervised time with peers, sports, organized activities, and paid employment--in relation to tobacco, alcohol, and marijuana use at the end of high school. Other research has examined these OST contexts in isolation, limiting efforts to disentangle potentially confounded relations. Longitudinal data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 766) examined associations between different OST contexts during high school and substance use at the end of high school. Unsupervised time with peers increased the odds of tobacco, alcohol, and marijuana use, whereas sports increased the odds of alcohol use and decreased the odds of marijuana use. Paid employment increased the odds of tobacco and alcohol use. Unsupervised time with peers predicted increased amounts of tobacco, alcohol, and marijuana use, whereas sports predicted decreased amounts of tobacco and marijuana use and increased amounts of alcohol use at the end of high school. Although unsupervised time with peers, sports, and paid employment were differentially linked to the odds of substance use, only unsupervised time with peers and sports were significantly associated with the amounts of tobacco, alcohol, and marijuana use at the end of high school. These findings underscore the value of considering OST contexts in relation to strategies to promote adolescent health. Reducing unsupervised time with peers and increasing sports participation may have positive impacts on reducing substance use. Copyright © 2015 Society for Adolescent Health and Medicine.

1990-02-05

A survey of 19 166 secondary schoolchildren aged 12-17 years in five Australian states, the Australian Capital Territory and the Northern Territory was undertaken in 1987 to determine the prevalence of tobacco and alcohol use. Current smoking (that is, smoking at least one cigarette in the last week) rose with age to 27% in boys who were aged 16 years and to 30% in girls who were aged 16 years. The prevalence of current drinking (that is, consuming one alcoholic drink in the last week) rose with age to 55% in boys who were aged 16 years and to 50% in girls who were aged 17 years. Compared with an identical survey in 1984, the prevalence of smoking among 12- to 17-year-old schoolchildren had fallen significantly. The prevalence of drinking alcohol among 12- to 15-year-old schoolchildren also had fallen significantly, but not to the same extent as that of smoking; no significant reduction was found in the drinking of alcohol among 16- to 17-year-old schoolchildren. These trends are encouraging, but a need remains for all states to enact tobacco-control legislation, including the prohibition of tobacco advertising.

Studies suggest marijuana impacts gray and white matter neural tissue development, however few prospective studies have determined the relationship between cortical thickness and cannabis use spanning adolescence to young adulthood. This study aimed to understand how heavy marijuana use influences cortical thickness trajectories across adolescence. Subjects were adolescents with heavy marijuana use and concomitant alcohol use (MJ+ALC, n=30) and controls (CON, n=38) with limited substance use histories. Participants underwent magnetic resonance imaging and comprehensive substance use assessment at three independent time points. Repeated measures analysis of covariance was used to look at main effects of group, time, and Group × Time interactions on cortical thickness. MJ+ALC showed thicker cortical estimates across the brain (23 regions), particularly in frontal and parietal lobes (ps<.05). More cumulative marijuana use was associated with increased thickness estimates by 3-year follow-up (ps<.05). Heavy marijuana use during adolescence and into young adulthood may be associated with altered neural tissue development and interference with neuromaturation that can have neurobehavioral consequences. Continued follow-up of adolescent marijuana users will help understand ongoing neural changes that are associated with development of problematic use into adulthood, as well as potential for neural recovery with cessation of use.

2016-01-01

Objective: Marijuana use can result in a variety of negative consequences, yet it remains popular among young adults and the general public at large. Combined with the growing empirical support for the benefits of medicinal marijuana as well as the steady increase in popular opinion regarding its legalization, it is of growing importance to identify strategies that may mitigate the harms related to marijuana use, reduce consumption levels, and limit resulting negative consequences among young adults who use marijuana. The purpose of this study was to develop and conduct initial psychometric analyses on a new scale, which we named the Protective Behavioral Strategies for Marijuana (PBSM) scale. Method: A sample of undergraduate college students who reported past-6-month marijuana use (n = 210) responded to the initial pool of PBSM items and completed measures of marijuana use, consequences from marijuana use, alcohol use, and protective behavioral strategies for alcohol. Results: Results from an iterative principal component analyses process yielded a single-factor structure with 39 items. The PBSM mean composite score negatively associated with marijuana use and consequences, with the strongest correlations evident for past-month users. The PBSM also significantly positively correlated with alcohol protective strategies. Conclusions: Protective behavioral strategies for marijuana appear to be a measurable construct that are related to marijuana frequency and consequences, and thus may be a useful component of intervention and prevention programs with young adults. More work testing the PBSM items with larger and more diverse samples of young adults is encouraged. PMID:27172576

Although alcohol and nicotine administration studies have demonstrated that manipulating subjects’ expectancies regarding drug content affects drug response, research with marijuana has not adequately studied drug expectancy effects. The present pilot study was the first to evaluate the credibility and effect of expectancy manipulation on subjective measures and smoking patterns using a marijuana administration balanced-placebo design (BPD). In a 2 × 2 instructional set (told delta-9-tetrahydrocannabinol [THC] vs. told no THC) by drug (smoked marijuana with 2.8% THC vs. placebo) between-subjects design, the authors examined the effect of marijuana expectancy manipulation and the pharmacologic effect on affective and physiologic measures, cigarette ratings, and smoking behavior with 20 marijuana smokers (mean age = 20 years; 25% female). Large main effects of expectancy were found on ratings of cigarette potency, strength, taste, smell, and satisfaction, and observed smoking behavior. Pharmacologic effects were particularly evident for self-reported physical reactions to marijuana and cigarette potency and satisfaction ratings. This study demonstrated the feasibility of the BPD research with marijuana and yielded promising results for future studies examining the independent and combined effects of marijuana pharmacology and expectancies.

This review provides an up-to-date curated source of information on alcohol, tobacco, and illicit drug use and their associated mortality and burden of disease. Limitations in the data are also discussed, including how these can be addressed in the future. Online data sources were identified through expert review. Data were mainly obtained from the World Health Organization, United Nations Office on Drugs and Crime, and Institute for Health Metrics and Evaluation. In 2015, the estimated prevalence among the adult population was 18.3% for heavy episodic alcohol use (in the past 30 days); 15.2% for daily tobacco smoking; and 3.8%, 0.77%, 0.37%, and 0.35% for past-year cannabis, amphetamine, opioid, and cocaine use, respectively. European regions had the highest prevalence of heavy episodic alcohol use and daily tobacco use. The age-standardised prevalence of alcohol dependence was 843.2 per 100,000 people; for cannabis, opioids, amphetamines and cocaine dependence it was 259.3, 220.4, 86.0 and 52.5 per 100,000 people, respectively. High-Income North America region had among the highest rates of cannabis, opioid, and cocaine dependence. Attributable disability-adjusted life-years (DALYs) were highest for tobacco (170.9 million DALYs), followed by alcohol (85.0 million) and illicit drugs (27.8 million). Substance-attributable mortality rates were highest for tobacco (110.7 deaths per 100,000 people), followed by alcohol and illicit drugs (33.0, and 6.9 deaths per 100,000 people, respectively). Attributable age-standardised mortality rates and DALYs for alcohol and illicit drugs were highest in Eastern Europe; attributable age-standardised tobacco mortality rates and DALYs were highest in Oceania. In 2015 alcohol and tobacco use between them cost the human population more than a quarter of a billion disability-adjusted life years, with illicit drugs costing a further tens of millions. Europeans proportionately suffered more but in absolute terms the mortality rate was

Background The association of attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) with tobacco and alcohol use has not been assessed in a young adolescent sample representative of the U.S. population. Methods Data are from the 2000–2004 National Health and Nutrition Examination Survey, a cross-sectional sample representative of the U.S. population. Participants were age 12–15 years (N=2517). Exposure variables included diagnosis of ADHD and CD, and counts of ADHD and CD symptoms based on caregiver responses to the Diagnostic Interview Schedule for Children. Primary outcomes were adolescent-report of any use of tobacco or alcohol and age of initiating use. Multivariate logistic regression and Cox proportional hazard models were conducted. Results Adolescents with ADHD+CD diagnoses had a 3- to 5-fold increased likelihood of using tobacco and alcohol and initiated use at a younger age compared to those with neither disorder. Having ADHD alone was associated with an increased likelihood of tobacco use but not alcohol use. Hyperactive-impulsive symptom counts were not independently associated with any outcome, while every one symptom increase in inattention increased the likelihood of tobacco and alcohol use by 8–10%. Although participants with a diagnosis of CD alone (compared to those without ADHD or CD) did not have a higher likelihood of tobacco or alcohol use, for every one symptom increase in CD symptoms the odds of tobacco use increased by 31%. Conclusions ADHD and CD diagnoses and symptomatology are linked to higher risk for a range of tobacco and alcohol use outcomes among young adolescents in the U.S. PMID:25487225

In January of 2014 the Regulate Marijuana like Alcohol Act or, Amendment 64, went into effect in Colorado. Even though it was the first state to enact recreational legalization, attitudes towards marijuana use have been changing for decades. Prompted by medical marijuana legalization, studies have found mixed results in regards to the impact that legalization has on frequency of use and abuse. With college students having the highest rates of use in the United States (U.S.), whether legal or not, it was important to explore the impact that legalization has on this population. In the current study, rates of marijuana and alcohol use in college students before and after recreational legalization were explored. Data was collected in four waves from October 2013 to March 2015, to be able to determine the trends in marijuana and alcohol use, and relationship between the substances. In addition, grade point average was measured as a possible consequence of marijuana use. We found the frequency of marijuana use in Colorado college students is much higher than the national average t(94445)=24.424, p<0.001, especially the percentage of daily or almost daily users, t(2191)=10.373, p<0.001. There were significant differences between the marijuana non-users and the once a week or more often but not daily marijuana users in grade point average, F(6, 227)=2.935, p<0.001. In addition, it seems that the relationship between alcohol and marijuana use in general is decreasing since the passing of Amendment 64, but not among the binge drinkers.

This study examined whether a brief video intervention (Prevention of Post-Rape Stress [PPRS]) delivered in the emergency department to recent sexual assault (SA) victims reduced alcohol and marijuana use at 3 points over the course of a 6-month follow-up compared to treatment as usual (TAU) and an active control condition (Pleasant Imagery and Relaxation Instruction [PIRI]). Prior assault history, minority status, and pre-SA substance use also were examined as moderators of intervention efficacy. Women aged 15 and older (N = 154) who participated in a post-SA medical forensic examination were randomly assigned to watch the PPRS video (n = 54) or the PIRI video (n = 48) or receive TAU (n = 52) and completed at least 1 follow-up assessment targeted at 1.5 (T1), 3 (T2), or 6 (T3) months following the examination. Regression analyses revealed that, relative to TAU, PPRS was associated with less frequent alcohol use at 6 months post-SA among women reporting pre-SA binge drinking and minority women. Relative to TAU, PPRS also was associated with fewer days of marijuana use at T1 among those who did not report pre-SA marijuana use and prior SA. Findings for pre-SA marijuana use were maintained at T3; however, findings for prior SA shifted such that PPRS was associated with fewer days of marijuana use at T3 for women with a prior SA. PPRS may be effective at reducing substance use for some recent SA victims, including those with a prior SA history, a prior substance use history, and minority women.
