BACKGROUND: The impact of secondhand marijuana smoke exposure on children is unknown. New methods allow detection of secondhand marijuana smoke in children. METHODS: We studied children ages 1 month to 2 years hospitalized with bronchiolitis in Colorado from 2013-2015. Parents completed a survey, and urine samples were analyzed for cotinine using LC/MS/MS (LOD 0.03 ng/ml) and marijuana metabolites including COOH-THC (LOD 0.015 ng/ml). RESULTS: A total of 43 subjects had urine samples available for analysis...

Commercial sex venues (CSVs) and public sex environments (PSEs) offer men who have sex with men (MSM) sexual privacy and anonymity. Sociodemographic characteristics (e.g., race/ethnicity, sexual identity, age, HIV status) are correlated with individuals' choice of sexual venue, potentially suggesting environmental associations with both sociodemographics and sexual risk. From March 2005 through March 2012, 1298 substance-using MSM provided information on their most recent sexual encounter; iterative logit models estimated associations between sociodemographics and sexual venue, and/or whether sexual venue was associated with sexual risk-taking while controlling for sociodemographics...

There are two main varieties of Cannabis sativa plant, namely, hemp which is cultivated for fiber and seeds and contains low amounts of psychoactive cannabinoids and the other which is cultivated for the drug cannabis or marijuana. Increasing popularity of hemp food products and alleged beneficial effects of cannabinoids in the drug variety of cannabis might lead to confusion in the lay population and unintentional ingestion of marijuana, as described in this case report. During a workshop on the use of hemp for medicinal purposes, there was a degustation of various hemp food products including also cookies that were brought by one of the attendees...

Cannabis and cannabinoids are known to affect female reproduction. However, the role of the endocannabinoid system in mouse uterine contractility in the dioestrus and oestrus phases has not been previously investigated. The present study aimed at filling this gap. Endocannabinoid (anandamide and 2-arachidonoylglycerol) levels were measured in mouse uterus at dioestrus and oestrus phases by liquid chromatography-mass spectrometry; quantitative reverse transcription-PCR measured mRNA expression of cannabinoid receptors and enzymes involved in the metabolism of endocannabinoids...

BACKGROUND: Most Brazilian schools do not have a continuous program for drug use prevention and do not conduct culturally adapted activities for that purpose. This study evaluated the impact of the Unplugged program on drug use prevention among children and adolescents in public middle schools of Brazil. METHODS: A non-randomized controlled trial was conducted in 2013 with 2185 students in 16 public schools from 3 Brazilian cities. The intervention group attended 12 weekly classes of the Unplugged program for drug use prevention, and the control group did not attend to any school prevention programs in the same year...

BACKGROUND: Some types of sexually transmitted infection (STI) have higher prevalence in females than males, and among black, relative to white, females. Identifying mechanisms of STI risk is critical to effective intervention. We tested a model in which alcohol and marijuana use serve as mediating factors in the associations between depression and conduct problems with sexual risk behavior (SRB) and STI in adolescent females. METHODS: The Pittsburgh Girls Study is a longitudinal observational study of females who have been followed annually to track the course of mental and physical health conditions...

BACKGROUND AND AIMS: Alcohol and marijuana are widely used among college students. Emotion regulation strategies have been linked to alcohol and marijuana use but little attention has been devoted to modeling the directionality of these associations. Aims of the current study were to test whether (a) daytime use of emotion regulation strategies influences the likelihood of evening substance use and (b) evening substance use influences the likelihood of next-day use of emotion regulation strategies...

BACKGROUND: Marijuana is currently the most commonly used illicit drug in the United States, and with the movement toward legalization of recreational marijuana, the country faces numerous issues regarding policy, prevention, and treatment of marijuana use. The present study examines the prevalence of marijuana use and consequences and compares users and non-users on a wide range of other marijuana-related constructs among college students across 11 universities. METHOD: Participants included 8141 college students recruited from the psychology department participant pools of 11 universities throughout the US, including four major regions of the US (West, South, Midwest, Northeast) and states with varying policies regarding the legality of marijuana use...

Most of the research on public perceptions of people with addictive disorders has focused on alcohol and illicit drugs, rather than addiction to behavioral activities. To expand the range of addictive behaviors and types of perceptions studied, we designed the present study to assess the lay public's definitions of and willingness to affiliate with people described as addicted to 1 of 2 specific behaviors (i.e., pornography or gambling) or 1 of 3 specific substances (i.e., alcohol, marijuana, or heroin). A nationwide convenience sample (N = 612) of American adults completed online questionnaires during the summer of 2015...

INTRODUCTION: The social developmental processes by which child maltreatment increases risk for marijuana use are understudied. This study examined hypothesized parent and peer pathways linking preschool abuse and sexual abuse with adolescent and adult marijuana use. METHODS: Analyses used data from the Lehigh Longitudinal Study. Measures included child abuse (physical abuse, emotional abuse, domestic violence, and neglect) in preschool, sexual abuse up to age 18, adolescent (average age=18years) parental attachment and peer marijuana approval/use, as well as adolescent and adult (average age=36years) marijuana use...

O Phan, I Obradovic, A Har
Over the past 10 years, the consumption of cannabis among adolescents has dramatically increased. Today, adolescent cannabis use is a major public health problem. Two forms of cannabis are commonly smoked: herb (marijuana) and resin. These forms have a high concentration of tetrahydrocannabinol, the active molecule of cannabis. Recent research has helped understand how the cannabinoid system works. This system combines specific receptors and specific molecules: the endocannabinoids. The effects of cannabis use are now well documented...

OBJECTIVES: Research suggests that individual and environmental resilience protective factors may be associated with adolescent substance use; however, the associations between a broad range of such factors and use of various types of substances have not been examined. The study aimed to determine the association between a comprehensive range of adolescent individual and environmental resilience protective factors and measures of tobacco, alcohol and illicit substance use. DESIGN: Cross-sectional study...

BACKGROUND AND AIMS: Screening, brief intervention and 'referral to treatment' programs have been widely promoted as US federal policy. Little is known about the efficacy of the RT component (referral to treatment) of brief intervention for motivating patients with unhealthy drug use identified by screening to use addiction treatment. This study aimed to compare receipt of addiction treatment following two types of brief intervention for drug use vs a no-intervention control group among primary care patients screening positive for drug use...

The endocannabinoid system (ECS), which is composed of the cannabinoid receptors types 1 and 2 (CB1 and CB2) for marijuana's psychoactive ingredient Δ(9)-tetrahydrocannabinol (Δ(9)-THC), the endogenous ligands (AEA and 2-AG) and the enzymatic systems involved in their biosynthesis and degradation, recently emerged as important modulator of emotional and non-emotional behaviors. For centuries, in addition to its recreational actions, several contradictory claims regarding the effects of Cannabis use in sexual functioning and behavior (e...

AIM: Concurrently with increasingly permissive attitudes towards marijuana use and its legalization, the prevalence of marijuana use has increased in recent years in the U.S. Substance use is generally more prevalent in men than women, although for alcohol, the gender gap is narrowing. However, information is lacking on whether time trends in marijuana use differ by gender, or whether socioeconomic status in the context of the Great Recession may affect these changes. METHODS: Using repeated cross-sectional data from the National Survey on Drug Use and Health (2002-2014), we examined changes over time in prevalence of past-year marijuana use by gender, and whether gender differences varied across income levels...
