BACKGROUND We determine trends in fatal pediatric drug overdose from 1999 to 2018 and describe the influence of contextual factors and policies on such overdoses. METHODS Combining restricted CDC mortality files with data from other sources, we conducted between-county multilevel models to examine associations of demographic and socioeconomic characteristics with pediatric overdose mortality and a fixed-effects analysis to identify how changes in contexts and policies over time shaped county-level fatal pediatric overdoses per 100,000 children under 12 years. RESULTS Pediatric overdose deaths rose from 0.08/100,000 children in 1999 to a peak of 0.19/100,000 children in 2016, with opioids accounting for an increasing proportion of deaths. Spatial patterns of pediatric overdose deaths are heterogenous. Socioeconomic characteristics are not associated with between-county differences in pediatric overdose mortality. Greater state expenditures on public welfare (B = -0.099; CI: [-0.193, -0.005]) and hospitals (B = -0.222; CI: [-.437, -.007]) were associated with lower pediatric overdose mortality. In years when a Good Samaritan law was in effect, the county-level pediatric overdose rate was lower (B = -0.095; CI: [-0.177, -0.013]). CONCLUSIONS Pediatric overdose mortality increased since 1999, peaking in 2016. Good Samaritan laws and investment in hospitals and public welfare may temper pediatric overdoses. Multi-faceted approaches using policy and individual intervention is necessary to reduce pediatric overdose mortality. IMPACT Pediatric fatalities from psychoactive substances have risen within the U.S. since 1999. Higher levels of state spending on public welfare and hospitals are significantly associated with lower pediatric overdose mortality rates. The implementation of Good Samaritan laws is significantly associated with lower pediatric overdose mortality rates. We identified no county-level sociodemographic factors associated with pediatric overdose mortality. The findings indicate that a multi-faceted approach to the reduction of pediatric overdose is necessary.

BackgroundSharing and gifting cigarettes are common in China. These social practices promote cigarette consumption, and consequently may reduce quit rates in China. This study investigated sharing and gifting cigarettes, and the relationship of observing pictorial health warnings to attitudes towards sharing and gifting cigarettes in China.MethodsWe conducted an online nationwide cross-sectional study of 9818 adults in China. Experiences of sharing and gifting cigarettes, and attitudes towards sharing and gifting cigarettes before and after viewing text and pictorial health warnings on the packages were assessed, and compared between smokers and non-smokers.ResultsMost current smokers reported experiences of sharing (97%) and gifting (around 90%) cigarettes. Less than half of non-smokers reported sharing cigarettes and receiving gifted cigarettes, but over half (61.4%) gave cigarettes as a gift to others. More than half of non-smokers but less than 10% of smokers disagreed with sharing and gifting cigarettes. After observing both text and pictorial health warnings on the packages, disagreement with sharing and gifting cigarettes increased by more than 10 percentage points among both smokers and non-smokers.ConclusionHaving pictorial health warnings on cigarette packages may reduce sharing and gifting cigarettes in China.

E-cigarette users’ beliefs about COVID-19 may shape their responses to the pandemic and their e-cigarette consumption. A U.S. national cross-sectional survey of 562 e-cigarette users was conducted in April 2020. Participants self-reported nicotine consumption, COVID-19 beliefs, beliefs about e-cigarettes, social distancing, COVID-19 disruptions, cessation considerations, and individual characteristics. Ordinary least squares (OLS) regression provided unstandardized, and standardized coefficients. Frequency of e-cigarette use is inversely associated with beliefs COVID-19 is relevant (β = −0.215). Beliefs e-cigarettes are addictive, harmful, or pose a risk to future health were positively associated with beliefs COVID-19 is relevant (β = 0.171; β = 0.164; β = 0.203), beliefs the media are truthful on COVID-19 (β = 0.133; β = 0.136; β = 0.137), and beliefs e-cigarette users are at greater risk (β = 0.279; β = 0.411; β = 0.447). All three COVID-19 beliefs (COVID relevant; media truthful; and greater risk) were positively associated with social distancing (β = 0.307; β = 0.259; β = 0.115), work disruptions (β = 0.134; β = 0.135; β = 0.130), family disruptions (β = 0.232; β = 0.131; β = 0.164), friendship disruptions (β = 0.214; β = 0.139; β = 0.133), and considerations of quitting (β = 0.250; β = 0.222; β = 0.620). Strong associations between e-cigarette beliefs and COVID-19 beliefs exist. COVID-19 beliefs are associated with behavioral responses, such as social distancing and considerations of e-cigarette cessation. Interventions may be able to leverage COVID-19 beliefs to reduce e-cigarette consumption or promote cessation during the pandemic.

Objective The objective of this study is to understand the perceived needs for information on maternal and infant healthcare during the puerperium among the fathers of newborns in China, and to examine factors that are associated with the patterns of perceived needs. Design A cross-sectional study was conducted. Methods A survey was conducted in the obstetrics department of the First Affiliated Hospital of Soochow University in Suzhou, China. A total of 206 fathers of newborns were interviewed with a response rate of 98.1%. Latent class analysis (LCA) was used to identify a priori unknown patterns of perceived needs for information (knowledge/skills) on maternal and infant healthcare during the puerperium period. Chi-square tests were applied to examine factors associated with such patterns of needs. Results The majority of the participants perceived strong needs for information on maternal and infant healthcare during the puerperium. LCA identified three latent classes on perceived needs for information on maternal healthcare among Chinese fathers of newborns: Class 1 - Low: Some Infant Health Related Needs; Class 2 - Moderate: Lower Physical Recovery Needs; and Class 3 - High: Enthusiastic Needs. Similarly, three latent classes were identified for perceived needs for information on infant health care: Class 1 - Low: Some Medical Needs; Class 2 - Moderate: Lower Breastfeeding Needs; and Class 3 - High: Enthusiastic Needs. Fathers aged 30 to 35, urban residents, and those with higher education were more likely to be in the Enthusiastic Needs groups for information needs for both maternal and infant healthcare. Conclusions Perceived needs for information on maternal and infant healthcare are widespread among fathers of newborns in China. Three distinct latent classes for perceived needs for information (knowledge/skills) on maternal and infant health were identified in this population. Socio-demographics, such as age, residence, and education, were significantly associated with such patterns of needs. The findings have implications for the development of interventions to improve maternal and infant healthcare in China.

Background Drug overdoses have contributed to considerable years of life lost. However, focusing solely on drug overdoses, whereby drug poisoning defines the underlying cause of death, obscures the wider burden of the drug mortality crisis. We aim to describe 21 years of trends in “psychotropic-drug-implicated deaths,” those where psychotropic drugs are a contributing (but not the underlying) cause of death. Methods We analyze deaths extracted from CDC WONDER from 1999−2019 to generate annual counts and rates for psychotropic-drug-implicated deaths in the United States, including by underlying cause of death and drug implicated. Results Over 21 years, 51,446 psychotropic-drug-implicated deaths occurred (33,885 medical; 17,561 external). Both medical and external psychotropic-drug-implicated deaths rose dramatically, increasing 2.5 and 5.0 times, respectively. Diseases of the circulatory system predominated underlying causes of medical deaths (74 %). Non-drug suicide, transport accidents, and drownings constitute 54 % of external underlying causes. Among the various underlying causes of death, psychotropic-drug-implicated deaths represent a considerable proportion, especially among external causes, with the proportion greatly increasing over the observation period. The drug implicated evolves from cocaine to opioids to psychostimulants, with the latter rising considerably. Conclusions The drug mortality crisis extends beyond overdose and may temper improvements observed within other causes of mortality, such as cardiovascular disease, transport accidents, and drownings. As with overdoses, psychotropic-drug-implicated deaths have risen dramatically during the 21st century. They include striking increases for drugs, such as psychostimulants, receiving less attention with overdoses. Research is needed to address prevention, intervention, and policy for psychotropic-drug-implicated deaths beyond overdose mortality.

Aims To evaluate the catalyst, diversion and common liability hypotheses by examining associations between e-cigarette use and tobacco cigarette smoking at modal ages 14 and 17 years, controlling for adolescent and infancy risk factors. Design Intergenerational, prospective cohort data from the Millennium Cohort Study (MCS). Nationally representative sample of infants born September 2000 to January, 2002. Setting United Kingdom. Participants Parent and child data from 10 625 youth assessed in infancy and modal ages 11, 14 and 17 years. Measurements Age 14 and 17 e-cigarette and combustible cigarette use (recency, frequency). Potential confounders were age 11 risk factors (e.g. alcohol use, externalizing behaviors, parental tobacco use, permissiveness), infancy risk factors (e.g. maternal smoking during pregnancy, smoke exposure in infancy) and demographic characteristics. Findings Among youth who had not smoked tobacco by age 14 (n = 9046), logistic regressions estimated that teenagers who used e-cigarettes by age 14 compared with non-e-cigarette users, had more than five times higher odds of initiating tobacco smoking by age 17 [odds ratio (OR) = 5.25, 95% confidence interval (CI) = 3.28-8.38] and nearly triple the odds of being a frequent tobacco smoker at age 17 (OR = 2.91, 95% CI = 1.56-5.41), net of risk factors and demographics. Among youth who had not used e-cigarettes by age 14 (n = 9078), teenagers who had smoked tobacco cigarettes by age 14 had three times higher odds of initiating e-cigarettes by age 17 (OR = 2.98, 95% CI = 1.74-5.09) compared with non-tobacco smokers and nearly three times higher odds of frequently using e-cigarettes at age 17 (OR = 2.90, 95% CI = 1.21-6.95), net of confounders. Similar links between e-cigarette and tobacco cigarette use were observed in regressions following coarsened exact matching. Conclusions E-cigarette use by age 14 is associated with increased odds of tobacco cigarette initiation and frequent smoking at age 17 among British youth. Similarly, tobacco smoking at age 14 is associated with increased odds of both e-cigarette initiation and frequent use at age 17.

INTRODUCTION AND AIMS: Participation in nightlife influences a range of health behaviours. Participants in various nightlife scenes have increasingly adopted prescription drug misuse into their substance use repertoires. DESIGN AND METHODS: With 404 young adults recruited via time-space sampling in New York, we examine the relationship of nightlife participation-measured by number of scenes and the number of nights out in nightlife scenes-to prescription drug misuse during the past 3 months. Outcomes included frequency of misuse, escalation to non-oral consumption, polydrug use, social problems and symptoms of dependence. RESULTS: Negative binomial regressions indicate nightlife participation is associated with increased frequency of misuse measured by number of scenes (incidence rate ratio = 1.114, P < 0.05) and number of nights out (incidence rate ratio = 1.009, P < 0.001). Logistic regression models show nightlife participation is associated with increased odds of non-oral use (adjusted odds ratio; AOR = 1.334, P < 0.01) and polydrug use (AOR = 1.776, P < 0.001) measured by number of scenes, and non-oral use (AOR = 1.021, P < 0.001) and polydrug use (AOR = 1.023, P < 0.001) as measured by number of nights out. Nightlife participation is not associated with prescription drug problems or symptoms of dependence. Frequency of participation is associated with peer norms favourable to prescription drugs (B = 0.003, P < 0.01). DISCUSSION AND CONCLUSIONS: Nightlife participation has implications for prescription drug misuse. While shaping how often and in what manner young people consume prescription drugs, nightlife participation is not associated with harms experienced. Given the significance of the prescription drug trend in many world regions, these results suggest that increasing participation in nightlife shapes patterns of drug use, but in ways that do not lead to reported problems.

Background Sleep problems are common in the general population. Cigarette smoking is common in the general population of China. Examinations of the prevalence of poor sleep quality among Chinese smokers and nonsmokers are still lacking. This study was designed to examine sleep quality and sleep disturbances among cigarette smokers and nonsmokers in the general population in central China. Methods In this population-based sampling project, we used a multi-stage sampling method to recruit survey participants from September 2012 to October 2012 in rural and urban areas of Hunan province, China. A total of 27,300 subjects were sampled from the general population and 26,282 completed the self-report of cigarette smoking characteristics. Cigarette smoker was defined as having smoked ≥100 cigarette in a lifetime and smoked during the last 28 days. Cigarette smoking characteristics were obtained from smokers, including cigarettes per day, years of smoking, quit attempts, and smoking cravings. The Pittsburgh Sleep Quality Index (PSQI) was applied to assess quality of sleep and sleep disturbances (PSQI score > 5). Results Significantly more smokers than nonsmokers demonstrated poor sleep quality and sleep disturbances. Among smokers, linear regression analyses showed that poor sleep was inversely associated with cigarettes per day, and positively associated with years of smoking, quit attempts, and smoking craving. Logistic regression analysis showed that quit attempts and smoking cravings were associated with higher odds of sleep disturbances. Conclusions Sleep disturbances were more prevalent among cigarette smokers than nonsmokers. Smokers also varied in sleep problems on the basis of the characteristics of their smoking. Smokers should be informed about the link between cigarette smoking and poor sleep quality, and should be advised that one of several important health benefits from smoking cessation could be the improvement of sleep quality. Sleep therapy should be recommended as an adjunctive treatment for smoking cessation.

The academic literature detailing escalations in pre-existing substance use practices is primarily understood through a biomedical lens, which situates drug escalation as a result of increases in biological markers like drug tolerance and dependence. This article seeks to frame the escalation of prescription drug misuse within a paradigm that situates drug use as a dynamic and interactional learning process shaped by set and setting. The data drawn upon for this article are derived from 41 qualitative interviews of young adults (aged 18–29 years) socially active in nightlife scenes who reported engaging in smoking prescription painkillers, sedatives, or stimulants. Results highlight how theories of drug use as a deviant behavior that is socially learned can be stretched beyond explaining patterns of initiation to also address the escalation of pre-existing drug use behaviors as users’ transition from one route of administration to another.

Widely used as a framework for understanding drug use initiation, social learning theory has lacked considerations of peer effects from the standpoint of the experienced user and applications to hard drugs. This study aims to extend social learning theory by examining the advice an experienced drug user would give a younger friend or relative expressing desire to experiment with club drugs. Forty qualitative interviews with club drugs users were analyzed. The experienced user’s own initiation, previous experiences, and risk perceptions are important in how advice is constructed. We discovered variations in advice-giving for friends and family members that may be based on considerations of age appropriateness.

Background Considering the extreme shortage of smoking cessation services in China, and the acceptability, feasibility and efficacy of mobile phone-based text message interventions for quitting smoking in other countries, here we propose a study of “the efficacy of mobile phone-based text message interventions (‘Happy Quit’) for smoking cessation in China”. The primary objective of this proposed project is to assess whether a program of widely accessed mobile phone-based text message interventions (‘Happy Quit’) will be effective at helping people in China who smoke, to quit. Based on the efficacy of previous studies in smoking cessation, we hypothesize that ‘Happy Quit’ will be an effective, feasible and affordable smoking cessation program in China. Methods/Design In this single-blind, randomized trial, undertaken in China, about 2000 smokers willing to make a quit attempt will be randomly allocated, using an independent telephone randomization system that includes a minimization algorithm balancing for sex (male, female), age (19–34 or >34 years), educational level (≤ or >12 years), and Fagerstrom score for nicotine addiction (≤5, >5), to ‘Happy Quit’, comprising motivational messages and behavioral-change support, or to a control group that receives text messages unrelated to quitting. Messages will be developed to be suitable for Chinese. A pilot study will be conducted before the intervention to modify the library of messages and interventions. The primary outcome will be self-reported continuous smoking abstinence. A secondary outcome will be point prevalence of abstinence. Abstinence will be assessed at six time points (4, 8, 12, 16, 20 and 24 weeks post-intervention). A third outcome will be reductions in number of cigarettes smoked per day. Discussion/Implications The results will provide valuable insights into bridging the gap between need and services received for smoking cessation interventions and tobacco use prevention in China. It will also serve as mHealth model for extending the public health significance of other interventions, such as mental health interventions. Trial registration NCT02693626 (Registration data April 11, 2016).

Objective to examine the psychometric properties of a newly developed Postpartum Women's Health Quotient Scale (PWHQS) for Chinese post partum women. Design a cross-sectional survey of post partum women was conducted.Categorical confirmatory factor analysis (CCFA) models were applied to examine the factorial structure of the PWHQS; test information function (TIF) was used to examine reliability of PWHQS subscales; and measurement invariance was examined by testing differential item functioning (DIF) using a multiple indicators multiple causes (MIMIC) model. Setting two large hospitals with a level 3A designation in Suzhou, Jiangsu Province, China. Participants a convenience sample of 395 post partum women was recruited from April to September 2014. Measurement the PWHQS consists of 31 items with 5 subscales: health consciousness (HC, 6 items), maternal health knowledge (MHK, 8 items), infant health knowledge (IHK, 6 items), maternal health care ability (MHCA, 5 items), and infant health care ability (IHCA, 6 items). Findings PWHQS has a valid factorial structure with five dimensions as theoretically designed. Each of its subscales has adequate reliability that is particularly high over the lower-moderate range of the factor score scale. Measurement non-invariance in PWHQS is very limited as only two of the 31 items displayed DIF related to one grouping variable (Age). Key conclusion PWHQS is a valid and reliable instrument that can be readily used as a screening tool to assess health quotient (HQ) among Chinese post partum women. PWHQS will also be useful for the development of interventions to help post partum women maintain and improve maternal and infant health. Further research to confirm the findings of the present study is desirable.

Among women and gay and bisexual men, sexual assault is associated with increased rates of sexual risk behavior and negative sexual health outcomes. Although the mechanisms of these effects are potentially myriad, the current analyses examine the role of perceived partner pressure for condomless sex in mediating the association between adult sexual assault (ASA) and recent anal or vaginal sex without a condom. In a sample of 205 young adult women and gay and bisexual men, ASA was indirectly associated with condomless anal and/or vaginal sex via perceptions of partner pressure for condomless sex, χ2(1) = 5.66, p = .02, after controlling for race, age, gender and sexual identity, and relationship status. The elucidation of this relational mechanism points to several potential intervention and prevention strategies that may reduce actual and perceived pressure for sex without a condom, including strategies designed to facilitate the prioritization of health and safety over relational goals and the improvement of partner selection and perceptions of partner pressure.

BACKGROUND: The U.S. has seen an unprecedented rise in opioid-related morbidity and mortality, and states have passed numerous laws in response. Researchers have not comprehensively established the effectiveness of pain management clinic regulations to reduce opioid prescribing using national data. METHODS: We combine a policy dataset from the Prescription Drug Abuse Policy System with the Centers for Disease Control and Prevention county-level opioid prescribing data, as well as with numerous government datasets for county- and state- level covariates. We predict retail opioid prescriptions dispensed per 100 people using county fixed-effects models with a state-level cluster correction. Our key predictors of interest are the presence of any state-level pain management clinic law and eight specific subcomponents of the law. RESULTS: Pain management clinic laws demonstrate consistent, negative effects on prescribing rates. Controlling for county characteristics, state spending, and the broader policy context, states with pain management clinic laws had, on average, 5.78 fewer opioid prescriptions per 100 people than states without such laws (p

Nightlife scenes have been characterized as risk environments where social ecology and network ties facilitate substance use. In contrast to other substances, the prescription drug problem also has been shaped by the healthcare system. How network ties to professionals in these domains are associated with prescription drug misuse remains a key area of study.We analyzed a sample of 404 young adults who misuse prescription drugs, recruited from nightlife venues primarily via time-space sampling. We evaluated nine types of network ties via friends and family (5 nightlife professions and 4 healthcare professions) as well as total ties in each occupational domain and their relationship to three different outcomes - frequency of misuse, escalation to non-oral use, and substance-related problems. Negative binomial, logistic, and linear regression methods were employed. We then examined mechanisms by which these network associations may operate.Ties to party promoters (p .05) and bouncers (p .01) were positively associated with all three outcomes. A single outcome each was associated with ties to DJs (problems, p .01), musicians (frequency, p .05), and bartenders (escalation, p .05). The total number of network ties in the nightlife domain was positively associated with all three outcomes, with each additional tie increasing frequency (20.3%, p .001), odds of escalation (OR = 42.9%, p .01), and problems (12.5%, p .01). The number of sources, peer norm context, and social bonding were explanatory mechanisms for all three outcomes for nightlife networks. Specific occupational ties and the total number of ties to healthcare professionals were not associated with any outcome.Embeddedness in nightlife networks is related to patterns of prescription drug misuse, and some of this association can be explained by multiple mechanisms of social networks. By contrast, ties to healthcare professionals are not associated with patterns of misuse among such young adults.

Background China has the highest global prevalence of cigarette smokers, accounting for more than 40% of the total cigarette consumption in the world. Considering the shortage of smoking cessation services in China, and the acceptability, feasibility, and efficacy of mobile-phone-based text messaging interventions for quitting smoking in other countries, we conducted a mobile-phone-based smoking cessation study in China. Methods and findings We conducted a randomized controlled trial in China across 30 cities and provinces from August 17, 2016, to May 27, 2017. Adult smokers aged 18 years and older with the intention to quit smoking were recruited and randomized to a 12-week high-frequency messaging (HFM) or low-frequency messaging (LFM) intervention (“Happy Quit”) or to a control group in a 5:2:3 ratio. The control group received only text messages unrelated to quitting. The primary outcome was biochemically verified continuous smoking abstinence at 24 weeks. Secondary outcomes included (1) self-reported 7-day point prevalence of abstinence (i.e., not even a puff of smoke, for the last 7 days) at 1, 4, 8, 12, 16, 20, and 24 weeks; (2) self-reported continuous abstinence at 4, 12, and 24 weeks; and (3) self-reported average number of cigarettes smoked per day. A total of 1,369 participants received 12 weeks of intervention or control text messages with continued follow-up for 12 weeks. The baseline characteristics of participants among the HFM (n = 674), LFM (n = 284), and control (n = 411) groups were similar. The study sample included 1,295 (94.6%) men; participants had a mean age of 38.1 (SD 9.79) years and smoked an average of 20.1 (SD 9.19) cigarettes per day. We included the participants in an intention-to-treat analysis. Biochemically verified continuous smoking abstinence at 24 weeks occurred in 44/674 participants in the HFM group (6.5%), 17/284 participants in the LFM group (6.0%), and 8/411 participants (1.9%) in the control group; participants in both the HFM (odds ratio [OR] = 3.51, 95% CI 1.64–7.55, p < 0.001) and the LFM (OR = 3.21, 95% CI 1.36–7.54], p = 0.002) intervention groups were more likely to quit smoking than those in the control group. However, there was no difference in quit rate between the HFM and LFM interventions. We also found that the 7-day point quit rate from week 1 to week 24 ranged from approximately 10% to more than 26% with the intervention and from less than 4% to nearly 12% without the intervention. Those who continued as smokers in the HFM group smoked 1 to 3 fewer cigarettes per day than those in the LFM group over the 24 weeks of trial. Among study limitations, the participants were able to use other smoking cessation services (although very few participants reported using them), cotinine tests can only detect smoking status for a few days, and the proportion of quitters was small. Conclusions Our findings demonstrate that a mobile-phone-based text messaging intervention (Happy Quit), with either high- or low-frequency messaging, led to smoking cessation in the present study, albeit in a low proportion of smokers, and can therefore be considered for use in large-scale intervention efforts in China. Mobile-phone-based interventions could be paired with other smoking cessation services for treatment-seeking smokers in China. Trial registration ClinicalTrials.gov NCT02693626., Jinsong Tang and colleagues report on a randomized trial done in China, aiming to evaluate a smoking cessation intervention based on texting., Author summary Why was this study done? China has the highest prevalence of cigarette smokers, accounting for more than 40% of the total cigarette consumption in the world. Smoking cessation remains the single most effective prevention measure for lung cancer and other smoking-related disorders and health conditions. The availability of smoking cessation services in China is extremely limited. Mobile-phone-based text messaging interventions for quitting smoking have proven cost-effective in other countries. What did the researchers do and find? We conducted a randomized controlled trial across various cities and provinces in China. The “Happy Quit” intervention consisted of text messages based on the principles of cognitive behavioral therapy. Messages were aimed at improving self-efficacy and behavioral capability for quitting. A total of 1,369 participants—674 in the high-frequency messaging group, 284 in the low-frequency messaging group, and 411 in the control group—received 12 weeks of intervention or control text messages, with an additional 12 weeks of follow-up. We found that biochemically verified continuous smoking abstinence at 24 weeks was 6.5% in the high-frequency messaging group, 6.0% in the low-frequency messaging group, and 1.9% in the control group. What do these findings mean? The findings of our trial suggest that a mobile-phone-based text messaging intervention (Happy Quit), with either high- or low-frequency messaging, is effective for Chinese cigarette smokers. This intervention should be considered for inclusion with smoking cessation services, and could be made widely available for smokers seeking treatment in China.

Smoke-free air laws and the denormalization of smoking are important contributors to reductions in smoking during the 21st century. Yet, tobacco policy and denormalization may intersect in numerous ways to affect smoking. We merge data from the National Longitudinal Survey of Youth 1997, Tobacco Use Supplement of the Current Population Survey, American Nonsmokers’ Right Foundation, and Census to produce a unique examination of the intersection of smoking bans and denormalization and their influence on any smoking and heavy smoking among young adults. Operationalizing denormalization as complete unacceptability of smoking within nightlife venues, we examine 1) whether smoking bans and denormalization have independent effects on smoking, 2) whether denormalization mediates the influence of smoking bans on smoking, and 3) whether denormalization moderates the impact of smoking bans on smoking. For any smoking, denormalization has a significant independent effect beyond the influence of smoking bans. For heavy smoking, denormalization mediates the relationship between smoking bans and habitual smoking. Denormalization does not moderate the relationship of smoking bans with either pattern of smoking. This research identifies that the intersection of denormalization and smoking bans plays an important role in lowering smoking, yet they remain distinct in their influences. Notably, smoking bans are efficacious even in locales with lower levels of denormalization, particularly for social smoking.

Purpose Alternative consumption practices of prescription drug misuse have been less well monitored than general prevalence. We describe prescription drug smoking among socially active youth and highlight correlates of this practice. We also examine its association with drug problems, drug dependence, and mental health. Methods We surveyed 404 young adults recruited from nightlife venues in New York via time-space sampling. We use linear and logistic regression models to examine the probability of smoking prescription drugs and its association with drug problems, dependence, and mental health. Qualitative findings supplement the survey data. Results Males have higher odds than females (odds ratio [OR] = 3.4), and heterosexuals have higher odds than sexual minority youth (OR = 2.3) of smoking prescription drugs. Those involved in electronic dance music nightlife have higher odds (OR = 2.1) than those who do not participate in that scene, whereas those in college bar scenes have lower odds (OR = .4) of having smoked prescription drugs. Prescription drug smokers report more drug problems (β = .322) and greater symptoms of dependence net (β = .298) of the frequency of misuse and other characteristics. Prescription drug smokers do not report greater mental health problems. Qualitative interview data support these survey findings. Conclusions Prescription drug smoking is a significant drug trend among socially active youth. It is associated with drug problems and symptoms of dependence net of frequency of misuse. Prevention and intervention efforts for youth who misuse prescription drugs should address the issue of prescription drug smoking, and this may be an area for clinicians to address with their adolescent patients.

Though research indicates a complex link between substance use and sexual risk behavior, there is limited research on the association between sexual risk behavior and prescription drug misuse. In light of alarming increases in prescription drug misuse and the role of demographic characteristics in sexual risk behavior and outcomes, the current study examined demographic differences (gender, sexual identity, age, relationship status, parental class background, and race/ethnicity) in sexual risk behavior, sexual behavior under the influence of prescription drugs, and sexual risk behavior under the influence of prescription drugs in a sample of 402 young adults (ages 18 to 29) who misused prescription drugs. Nearly half of the sexually active young adult prescription drug misusers in this sample reported recent sex under the influence of prescription drugs; more than three-quarters reported recent sex without a condom; and more than one-third reported recent sex without a condom after using prescription drugs. Zero-inflated Poisson regression models indicated that White race, younger age, higher parental class, and being a heterosexual man were all associated with sexual risk behavior, sex under the influence of prescription drugs, and sexual risk under the influence of prescription drugs. Findings have implications for the targeting of prevention and intervention efforts.

Objectives. To examine the influence of undocumented immigration in the United States on 4 different metrics of drug and alcohol problems: drug arrests, drug overdose fatalities, driving under the influence (DUI) arrests, and DUI deaths. Methods. We combined newly developed state-level estimates of the undocumented population between 1990 and 2014 from the Center for Migration Studies with arrest data from the Federal Bureau of Investigation Uniform Crime Reports and fatality information from the Fatality Analysis Reporting System and the Centers for Disease Control and Prevention Underlying Cause of Death database. We used fixed-effects regression models to examine the longitudinal association between increased undocumented immigration and drug problems and drunk driving. Results. Increased undocumented immigration was significantly associated with reductions in drug arrests, drug overdose deaths, and DUI arrests, net of other factors. There was no significant relationship between increased undocumented immigration and DUI deaths. Conclusions. This study provides evidence that undocumented immigration has not increased the prevalence of drug or alcohol problems, but may be associated with reductions in these public health concerns.

While a significant minority of prescription drug misusers report purchasing prescription drugs, little is known about prescription drug selling. We build upon past research on illicit drug markets, which increasingly recognizes networks and nightlife as influential, by examining prescription drug market involvement.We use data from 404 young adult prescription drug misusers sampled from nightlife scenes. Using logistic regression, we examine recent selling of and being approached to sell prescription drugs, predicted using demographics, misuse, prescription access, and nightlife scene involvement.Those from the wealthiest parental class and heterosexuals had higher odds (OR=6.8) of selling. Higher sedative and stimulant misuse (OR=1.03), having a stimulant prescription (OR=4.14), and having sold other illegal drugs (OR=6.73) increased the odds of selling. College bar scene involvement increased the odds of selling (OR=2.73) and being approached to sell (OR=2.09). Males (OR=1.93), stimulant users (OR=1.03), and sedative prescription holders (OR=2.11) had higher odds of being approached.College bar scene involvement was the only site associated with selling and being approached; such participation may provide a network for prescription drug markets. There were also differences between actual selling and being approached. Males were more likely to be approached, but not more likely to sell than females, while the opposite held for those in the wealthiest parental class relative to lower socioeconomic statuses. Given that misuse and prescriptions of sedatives and stimulants were associated with prescription drug market involvement, painkiller misusers may be less likely to sell their drugs given the associated physiological dependence.

Introduction and Aims Prescription drug misuse is a considerable problem among young adults, and the identification of types of misuse among this population remains important for prevention and intervention efforts. We use latent class analysis to identify possible distinct latent groups of prescription drug misusers across multiple prescription drug types (pain killers, sedatives and stimulants). Design and Methods Our data are comprised of a sample of 404 young adults recruited from nightlife scenes via time–space sampling. Through the specification of a zero-inflated Poisson latent class analysis, we evaluate differences in class membership by various demographic factors as well as assess the relationship between class membership and health outcomes, including indications of dependence, problems associated with substance use and mental health. Results Our assessment of fit indices led to a four-class solution (dabblers, primary stimulant users, primary downers users and extensive regulars). No demographic differences existed between latent classes. The extensive regular class report the greatest number of symptoms related to dependence, greatest number of problems related to misuse and the greatest mental health problems. The dabblers report the fewest problems and symptoms, while the other two classes experiences problems and symptoms in between the classes on the extremes. Discussion and Conclusions Prevention efforts should take into account that young adults who misuse prescription drug have different profiles of misuse, and there may be a need for varied interventions to target these different types of misuse.

Although substance abuse treatment has been considerably scaled up in China, impediments to accessing these services remain among drug users. The authors examine the primary psychosocial barriers to drug treatment in this population and evaluate factors associated with these barriers. Barriers to accessing drug treatment were measured using the Barriers to Treatment Inventory (BTI). A Structural Equation Model was used to examine whether the internal barriers were associated with treatment history and frequent methamphetamine use as well as how demographic characteristics influence such barriers. We found four primary factors of internal barriers to drug treatment – absence of problem, negative social support, fear of treatment, and privacy concerns – to fit well. Demographic factors, notably age and employment status, indirectly influence barriers to treatment via other factors. Frequency of methamphetamine use and drug treatment history are directly associated with the absence of problem and negative social support dimensions of the BTI, and it is through these pathways that demographic factors such as age and employment status shape barriers to treatment. The findings indicate that perceived absence of a problem and negative social support are the barriers most influenced by the personal domains of Chinese drug users’ lives. Efforts to engage drug users in China about drug treatment options may consider how these barriers are differentially perceived in order to effectively reach this population.

This article aims to introduce and demonstrate the application of the standardization and decomposition analysis (SDA) method to gauge differences in HIV prevalence rates among injection drug users (IDUs) across regions (Northeast, South, Midwest, and West) in the U.S. Using the SDA, the regional HIV prevalence rates were standardized and a rate difference between regions was decomposed into component effects, such as the "real" rate difference, and component effects attributed to differences in specific compositions of confounding factors. A total of 9,824 injection drug users (IDUs) retrieved from the national database of the National Institute on Drug Abuse's Cooperative Agreement for AIDS Community-Based Outreach/Intervention Research Program (COOP) projects constitute the sample for the study. A computer program DECOMP was used to implement the multi-population SDA.

The decision to initiate, maintain, or quit cigarette smoking is structured by both social networks and health beliefs. Self-exempting beliefs affect people's decisions in favor of a behavior even when they recognize the harm associated with it. This study incorporated the literatures on social networks and self-exempting beliefs to study the problem of daily smoking by exploring their mediatory relationships and the mechanisms of how smoking behavior is developed and maintained. Specifically, this article hypothesizes that social networks affect daily smoking directly as well as indirectly by facilitating the formation of self-exempting beliefs. The sample comes from urban male residents in Hangzhou, China randomly selected and interviewed through multistage sampling in 2011. Using binary mediation analysis with logistic regression to test the hypotheses, the authors found that (a) daily smoking is associated with having smokers in several social network arenas and (b) self-exempting beliefs about smoking mediate the association between coworker network and daily smoking, but not for family network and friend network. The role of social network at work place in the creation and maintenance of self-exempting beliefs should be considered by policymakers, prevention experts, and interventionists.

Drug treatment services of varying types have been scaled up in China over the past decade. Yet, barriers to treatment remain among the population of drug users in China. In this paper, we use a person-centered approach to examine external barriers to drug treatment among a sample of Chinese drug users. Specifically, we used a latent class analysis to determine a typology of external barriers to treatment among a sample of 262 drug users. The results of the analyses suggest three-classes of drug users with respect to their perceptions of external barriers to treatment – Major Barriers, Low Barriers, and Systems-level Barriers – indicating that drug users are a heterogeneous population on this matter. Age and types of drugs used were predictors of class membership. In this regard, different tactics must be utilized in order to successfully reach this wide ranging group of individuals.

Insomnia and the inability to sleep affect people’s health and well-being. However, its systematic estimates of prevalence and distribution in the general population in China are still lacking. A population-based cluster sampling survey was conducted in the rural and urban areas of Hunan, China. Subjects (n = 26,851) were sampled from the general population, with a follow-up using the Pittsburgh Sleep Quality Index (PSQI) for interview to assess quality of sleep and Insomnia (PSQI score >5). While the overall prevalence of insomnia was 26.6%, and little difference was found between males (26.3%) and females (27.0%); the mean PSQI score was 4.26 (±2.67), and significant higher in females (4.32 ± 2.70) than males (4.21 ± 2.64, p = 0.003). Individuals in the rural areas tended to report a higher PSQI score (4.45 ± 2.81) than urban residents did (4.18 ± 2.60) (p

Teenage girls in age-discordant relationships remain of concern for healthy development and well-being. We examine whether factors from several sociological frameworks—self-esteem, deviance, social ecology, family cohesion, and religious involvement—predict entry into such relationships. With longitudinal data on 1,537 adolescent girls, we use structural equation modeling to assess risk and protective factors by age group. Results indicate that few social factors predict entry to such relationships; only religious involvement for the youngest adolescents and self-esteem for middle adolescents predict entry. While adolescent girls who date older males are largely like their peers, any impact of social factors may vary by the developmental stage that adolescent girls occupy.

Introduction and Aims Youth cultures play a key role in the social organisation of drug trends among young people; the current prescription drug misuse trend is no different. The authors evaluated whether patterns of prescription drug misuse differed across several youth cultures. Design and Methods Using field survey methods and time–space sampling during 2011, the authors assessed the patterns and prevalence of prescription drug misuse among young adults who are socially active in various urban youth cultures (n = 1781). Results The prevalence of lifetime prescription drug misuse is highest within indie rock scenes (52.5%), electronic dance music scenes (52.1%), lesbian parties (53.8%) and alt scenes (50.9%). Prescription drug misuse was lowest among young adults in hip-hop scenes (25.0%). These findings were upheld in logistic regression analyses that accounted for demographic differences across youth cultures: indie rock scenes (adjusted odds ratio = 2.11), electronic dance music scenes (adjusted odds ratio = 2.20), lesbian parties (adjusted odds ratio = 2.30) and alt scenes (adjusted odds ratio = 2.65) all reported statistically significant (P

Gay neighbourhoods have historically served as vital places for gay socialising, and gay social networks are important sources of social support. Yet, few studies have examined the influence of these forms of community on sexual health. Informed by theoretical frameworks on neighbourhoods and networks, we employ multi-level modelling to test hypotheses concerning whether gay neighbourhoods and social network factors are associated with five sexual risk behaviours: receptive and insertive unprotected anal intercourse (UAI), barebacking identity, recent internet use for finding sexual partners, and 'Party and Play' (PnP). Our analyses of a community-based sample of gay men in New York City reveal little evidence for the direct effect of gay enclaves on sexual risk with the exception of PnP, which was more likely among gay enclave residents. Having a network composed predominantly of other gay men was associated with insertive UAI, PnP, and internet use for meeting sexual partners. This network type also mediated the association between gay neighbourhoods and higher odds of insertive UAI as well as PnP. Our findings highlight the sexual health implications of two important facets of gay community and, in doing so, indicate the need to better contextualise the sexual health risks faced by gay men.

Gay neighborhoods serve as vital places for gay men’s socializing, yet few studies have examined their contributions to gay men’s health—either directly or indirectly via residents’ social networks. Drawing from theoretical perspectives on community and networks, we test hypotheses concerning whether gay neighborhoods and social network factors are associated with patterns of recent illicit drug use among a sample of 740 urban gay men from New York City. Higher odds of drug use were observed among individuals who resided in gay neighborhoods, had networks composed predominantly of other gay men, and had increased socialization with gay men. Network factors did not mediate associations between gay neighborhoods and drug use. These findings highlight the need to better contextualize the health risks faced by gay men by accounting for both neighborhood and network structures.

Although non-medical prescription drug use has dramatically increased in many populations during the past decade, this phenomenon remains understudied among men who have sex with men (MSM). Using a community-based sample of MSM, we provide data on the high prevalence of lifetime and recent non-medical prescription drug use among MSM for a range of prescription drug classes such as pain killers, sedatives, sleep aids, stimulants, and erectile dysfunction medications. The paper also highlights differences in rates of recent non-medical prescription drug use within this population, noting that White MSM, HIV-positive MSM, gay-identified MSM, and MSM over 40 were typically more likely to have recently used a range of prescription drugs than their counterparts. After controlling for various factors, the findings demonstrate that age, HIV-positive status, gay identity, low educational level, and White race are significant correlates of both lifetime and recent non-medical prescription drug use among MSM. The data suggest that prevention and treatment efforts for this population are likely to require some tailoring, particularly for HIV-positive MSM who may have different needs than other MSM given their health concerns and medication regimens.

Objectives. Ketamine, methylenedioxymethamphetamine (MDMA/ecstasy), cocaine, gamma-hydroxybutyrate (GHB), methamphetamine, and d-lysergic acid diethylamide (LSD/acid) have been identified as “club drugs” because of their link to club culture among young adults. Yet little is known about users' demographic differences in the prevalence of club drugs. This study sought to provide a comprehensive profile of users' demographic differences in prevalence of club drug use and dependence. Methods. Using time-space sampling, a stratified sample of 400 18- to 29-year-old club-going young adults was recruited into the Club Drugs and Health Project. Results. Though participants reported using an array of club drugs, almost all participants (90.0%) were cocaine users. Although there were several sexual orientation and gender differences in recent drug exposure, patterns of use (measured in days) were fairly similar across gender, sexual orientation, and age. Finally, a majority of individuals (58.5%) met or exceeded criteria for club drug dependence, with most (61.7%) indicating cocaine was the one drug causing them significant problems. Conclusions. Cocaine is a major drug in club culture. It is essential to develop culturally appropriate drug education and prevention initiatives for young adults using club drugs.

Club drugs present a range of risks similar to the range of psychoactive effects resulting from the use of the substances in this classification. These drugs remain in wide use amongst those in rave and club subcultures. This paper explores a range of risk management practices used by youth who utilize club drugs within rave and club subcultures. Through the use of ethnographic methods during a two-year period of fieldwork, the author collected data on club drug use and risk taking among “Bridge and Tunnel” youth. The resulting paper provides a descriptive typology of a series of risk management practices and explores how these practices are strategically deployed in an effort to maximize enjoyment and minimize danger.

As part of a larger study on prescription drug misuse among young adults active in urban nightlife scenes, we examined participants' motivations for misuse. Prescription painkillers, stimulants and sedatives were the primary substances of interest.Participants were recruited from nightlife venues in New York using time-space sampling. Subjects completed a mixed-methods assessment at project research offices. The data presented here are from a subsample of 70 qualitative interviews conducted during the baseline assessment.We identified experimentation and a "work hard, play hard" ethos as key motivations for misusing prescription drugs and argue that these motivations are specific, though not necessarily unique, to the participants' social location as young adults. These findings highlight the role of life stage and social context in the misuse of prescription drugs.Future studies of prescription drug misuse should pay attention to the larger social contexts in which users are embedded and, therefore, make decisions about how and why to misuse. Moving beyond the very broad concepts of "recreation" and "self-medication" presently established in the research, policies targeting young adults may want to tailor intervention efforts based on motivations.

Objectives. We examined the mutual effects of smoking bans and taxes on smoking among a longitudinal cohort of young adults. Methods. We combined a repository of US tobacco policies at the state and local level with the nationally representative geocoded National Longitudinal Survey of Youth 1997 (2004–2011) from ages 19 to 31 years and Census data, to examine the impact of tobacco policies on any current and daily pack smoking. The analytic sample amounts to 19 668 observations among 4341 individuals within 487 cities. Results. For current smoking, we found significant effects for comprehensive smoking bans, but not excise taxes. We also found an interaction effect, with bans being most effective in locales with no or low taxes. For daily pack smoking, we found significant effects for taxes, but limited support for bans. Conclusions. Social smoking among young adults is primarily inhibited by smoking bans, but excise taxes only deter such smoking in the absence of a ban. Heavy smokers are primarily deterred by taxes. Although both policies have an impact on young adult smoking behaviors, their dual presence does not intensify each policy’s efficacy.

Bongs and blunts constitute significant elements of marijuana consumption in the United States, especially among youth. The author draws upon ethnographic methods to provide rich descriptions of these practices amongst a network of suburban marijuana users. The author first provides a description of bong use in a suburban home prior to detailing the same youth network engaging in the process of rolling and smoking a blunt in a public environment. Ultimately, the author examines and contrasts these two features of American marijuana consumption.

Purpose To examine the short-term effects on the sexual health of adolescent boys in age discordant relationships. Methods Weighted logistic regression analyses were conducted using data from waves 1 and 2 of the National Survey of Adolescent Health to determine the health effects of entry into an age discordant relationship on adolescent boys. Results Results indicate that boys involved in an age discordant relationship, in comparison with boys in a similar age relationship, had higher odds of having had sexual intercourse (OR = 2.92), having got a partner pregnant (OR = 1.89), having been diagnosed with STD (OR = 4.41), and having lost one's virginity (OR = 3.39). Analyses on the sexually active subset reveal no significant relationship between involvement in an age discordant relationship and birth control use broadly, or condom use specifically, at their most recent sexual intercourse. Conclusion In general, entering into an age discordant relationship as a younger partner is associated with some adverse sexual health effects for adolescent boys. Thus, some outcomes that were demonstrated in previous research to be problematic for adolescent girls dating significantly older males are similarly problematic for adolescent boys dating older females.

Although evidence exists for distinct barriers to drug abuse treatment (BDATs), investigations of their inter-relationships and the effect of individual characteristics on the barrier factors have been sparse, especially in China. A Multiple Indicators Multiple Causes (MIMIC) model is applied for this target.A sample of 262 drug users were recruited from three drug rehabilitation centers in Hunan Province, China. We applied a MIMIC approach to investigate the effect of gender, age, marital status, education, primary substance use, duration of primary drug use, and drug treatment experience on the internal barrier factors: absence of problem (AP), negative social support (NSS), fear of treatment (FT), and privacy concerns (PC).Drug users of various characteristics were found to report different internal barrier factors. Younger participants were more likely to report NSS (-0.19, p=0.038) and PC (-0.31, p0.001). Compared to other drug users, ice users were more likely to report AP (0.44, p0.001) and NSS (0.25, p=0.010). Drug treatment experiences related to AP (0.20, p=0.012). In addition, differential item functioning (DIF) occurred in three items when participant from groups with different duration of drug use, ice use, or marital status.Individual characteristics had significant effects on internal barriers to drug treatment. On this basis, BDAT perceived by different individuals could be assessed before tactics were utilized to successfully remove perceived barriers to drug treatment.

Prescription drug misuse has emerged as a significant problem among young adults. While the effects of motivational contexts have been demonstrated for illicit drugs, the role of motivational contexts in prescription drug misuse remains understudied. Using data from 400 young adults recruited via time-space sampling, we examined the role of motivational contexts in the frequency of misuse of three prescription drug types as well as drug-related problems and symptoms of dependency. Both negative and positive motivations to use drugs are associated with increases in prescription drug misuse frequency. Only negative motivations are associated directly with drug problems and drug dependence, as well as indirectly via prescription pain killer misuse. Addressing positive and negative motivational contexts of prescription drug misuse may not only provide a means to reduce misuse and implement harm reduction measures, but may also inform the content of treatment plans for young adults with prescription drug misuse problems.

Methamphetamine use has emerged in China over the past decade. With the growth in methamphetamine use, it remains uncertain how users in China perceive its association with the HIV epidemic.The authors utilize qualitative and survey data from a mixed-methods study on methamphetamine use and HIV risk in China to assess the extent to which users perceive a risk for HIV transmission as well as how they conceive of the drug's links to HIV.Data indicate that a considerable majority (82.2%) perceived themselves to have zero risk for HIV infection. Qualitative interviews highlight the lack of information about HIV possessed by methamphetamine users given the confusion and disbelief often expressed. Others acknowledged that while there was an intertwining of risk, they were not personally at risk.Given the known association between methamphetamine use and HIV risk, health promotion initiatives in China should target methamphetamine users to build HIV-related knowledge and inhibit self-exempting beliefs. In particular, educational efforts regarding the association of methamphetamine use with HIV may inhibit risk behaviors.

Men who have sex with men (MSM) misuse prescription drugs at high rates. Little research has examined the connection between prescription drug misuse and HIV risk in this population. With a community sample of MSM, the authors assessed prescription drug misuse—not including erectile dysfunction medications—and sexual risk behaviors among HIV-negative MSM. The findings indicate that recent prescription drug misusers had higher odds of engaging in unprotected anal intercourse (UAI; OR = 1.63), specifically receptive UAI (OR = 1.58), and more likely to have UAI with a higher number of seroconcordant partners (b = 0.268). MSM who reported recently misusing prescription drugs during sexual encounters were more likely to engage in UAI (OR = 2.02), specifically insertive UAI (OR = 1.86). There was no association between prescription drug misuse and identification as a barebacker. This research indicates that prescription drug misusing MSM are a risk group who may benefit from HIV prevention and intervention efforts.

This paper describes the role and implications of sampling and recruitment in qualitative drugs research. To provide further detail of some issues pertaining to sampling in qualitative and ethnographic projects, the author describes recent experiences utilizing theoretical sampling and time–space sampling to study club drug users. The author details practical challenges experienced with the implementation of these sampling methodologies and with the results they produced. Attention is paid to the role that the environmental factors at clubs play in the implementation of sampling methods, issues related to network methods in recruitment, and practical implications of managing team-based recruitment strategies.

This report assesses smoking rates and support for indoor smoking bans among club-going young adults in New York City. Nearly half of the sample were smokers. Gay, lesbian, and bisexual young adults were more likely to smoke than were heterosexual participants. No differences in smoking rates were found between sexes or between Whites and non-Whites. Support for the smoking ban exists among young adults (68.6%). This is universal, as no differences in support for the ban were found by sex, race, or sexual identity. Smokers supported the ban (57.8%) less than nonsmokers did (77.3%). Yet, it remains notable that a majority support the smoking ban among smokers.

In March 2003, New York City implemented legislation that called for a ban of smoking in bars, restaurants, nightclubs, and other establishments. The express purpose of this legislation was to protect the health of employees and patrons from second-hand smoke. In addition to the stated goal of protection from second-hand smoke for employees, key secondary health effects of this law have emerged in the lives of club-going youth. This paper is based upon data derived from an ethnographic research project on club-related health issues in NYC. Drawing upon ethnographic fieldwork during the implementation of the ban and in-depth interviews with club-going youth, the paper provides a grounded analysis of youth reactions to the smoking ban and a descriptive profile of the secondary health effects of the smoking ban in nightclubs. It explores the attitudes of club-going youth towards the ban and the ways in which the legislation shapes the behaviours of habitual smokers, 'social smoking', and the use of drugs within bars and clubs. In particular, the data suggest a tension between the desire to remain subculturally involved and the desire to smoke. It also highlights the adaptive character of subcultures and the importance of social relations in behavioural patterns.

Nonmedical prescription (Rx) drug use has recently increased, particularly among young adults. Using time-space sampling to generate a probability-based sample of club-going young adults (18-29), 400 subjects provided data on Rx drug misuse. Club-going young adults misuse Rx drugs at high rates. An overwhelming majority of the sample indicated lifetime use of pain killers, sedatives, and stimulants. A majority indicated recent pain killer use. Variations by gender and sexuality exist in this population. Young lesbian/bisexual women emerged as the group most likely to abuse Rx drugs. Research into the contexts influencing these patterns is imperative.
