Little research has examined mechanisms driving cannabis use disparities among sexual minority (SM; versus heterosexual) young adults (YAs). Participants were US YA women (N = 1345; 24.8% bisexual, 6.1% lesbian) and men (N = 998: 8.9% bisexual, 13.8% gay). Bivariate analyses examined associations between sexual orientation (heterosexual,…

The majority of U.S. adults believe that smoking is a cause of lung cancer, but research suggests that the percentage of adults who believe smoking causes other types of cancers and chronic disease is lower. This study examines the correlates of beliefs about several established health effects of smoking in a nationally representative sample of…

Background: The origin of inequalities in health outcomes has been explained by health selection and social causation models. Health selection processes operate particularly at school age. We study, if student allocation to teaching groups with aptitude tests (selective vs general class) differentiates adolescents by health behaviors and mental…

The aim of this study was to identify the association between type D personality and smoking cessation among high school students who had participated in a stop smoking program. From 27 high schools, we recruited 279 smoking students who had participated in a stop smoking program between May 29, 2015, and January 25, 2016. About 26.5% of…

Smokers are exposed to advice about quitting from numerous sources. Within the 2013 ITC 4-Country Survey, 1211 Australian smokers or recent ex-smokers rated the perceived importance of eight sources of advice, categorized into evidence-based, non evidence-based, personal experience and vicarious experience (two items each), and also rated their…

Health warning labels (HWLs) on cigarette packs that use strong fear appeals may evoke defensive responses including acts of disparaging the warnings. Whether warning disparagement undermines HWL effectiveness remains unclear. We assessed correlates of one type of HWL disparagement and its association with subsequent cessation attempts.…

Commitments to goals are theorized to affect behavior change outcomes, but competing theories argue for hard to achieve goals and strategic sub-goals as optimum strategies for success. This study aimed to explore whether the nature of the goal affects smoking cessation outcomes. A total of 1043 participants in a randomized controlled trial of…

Introduction: E-cigarette use remains a controversial topic in public health and medicine. Historically, cigarette smoking was identified as a gateway to marijuana use among adolescents. Recently, the prevalence of adolescent cigarette smoking has declined, but that of e-cigarette use continues to increase. As e-cigarettes eclipse cigarettes among…

Background: As conventional cigarette use is declining, electronic cigarette ("e-cigarette") use is rising and is especially high among college students. Few studies examine dual use of e-cigarettes and cigarettes among this population. This study explores the relationship between dual and exclusive e-cigarette / cigarette use and…

The present study investigated the prevalence and co-occurrence of addictions to tobacco, alcohol, other drugs, food/eating, the internet, texting, video games, shopping, love, sex, exercise, work, and gambling among American Indian (AI) youth in California. As with previous work in other cultural groups, the most prevalent addictions were love,…

The goal of this study was to examine behavioral norm effects in 2 peer contexts (classroom, school) on adolescent substance use (tobacco, alcohol, cannabis) and aggressive behaviors (bullying, physical fighting). Participants were 5,642 adolescents (M[subscript age] = 14.29 years, SD = 1.26; 49% boys). There were 3 hypotheses. First, behavioral…

Background: Early substance use co-occurs with youths' self-organization into deviant peer groups in which substance use is central to social interaction. We hypothesized that the social dynamics of deviant peer groups amplify the risk of progressing from early use to later dependence, and that this influence occurs over and above escalations…

Objective: Tobacco smoking and ADHD frequently co-occur. So far, the bulk of research on the ADHD-smoking comorbidity has been done in children with ADHD and nonclinical adult samples. To assess smoking habits in adults with ADHD, the authors used the Fagerstrom Test for Nicotine Dependence (FTND). Method: In 60 adult outpatients, with an ADHD…

Three main aims of this study were to ascertain the prevalence rate of smoking among adolescent psychiatric outpatients; estimate smokers' degree of nicotine dependence; and investigate the relationship between smoking and common mental health disorders. Face-to-face interviews were conducted on 93 patients ages 13-18 presenting to an adolescent…

This study provides analysis of a representative national sample of Internet gamblers. Using participant data from the 2007 British Gambling Prevalence Survey (n = 9003 adults aged 16 years and over), all participants who had gambled online, bet online, and/or who had used a betting exchange in the last 12 months (6% of the total sample) were…
