RATIONALE: Drug demand, or relative value, can be assessed via analysis of behavioral economic purchase task performance. Five demand indices are typically obtained from drug purchase tasks. OBJECTIVES: The goal of this research was to determine whether metrics of marijuana reinforcement from a marijuana purchase task (MPT) exhibit a latent factor structure that efficiently characterizes marijuana demand. METHODS: Participants were regular marijuana users (n = 99; 37...

Approximately 80% of all arrested youth are diverted from detention and supervised in the community through probation, specialty courts and other community-based diversion efforts. Justice-involved youth have greater psychiatric impairment, substance use and sexual risk behaviors than their non-justice-involved peers. Family-based interventions to address mental health, substance use and recidivism have been successful in improving these youth outcomes; but the lack of integration of HIV/STI prevention is notable given the co-occurrence of substance use, delinquency and sexual risk-taking behaviors among justice-involved youth...

Psychological reactance is typically assumed to motivate resistance to controlling peer influences and societal prohibitions. However, some peer influences encourage behaviors prohibited by society. We consider whether reactant individuals are sensitive to such opportunities to enhance their autonomy. We specifically propose a self-regulatory perspective on reactance, wherein freedom/autonomy is the superordinate goal, and thus highly reactant individuals will be sensitive to peer influences that could enhance their behavioral freedoms...

Motivation is an integral factor in substance use treatment and long-term recovery. However, it is unclear what role intrinsic and extrinsic motivation play across different treatment modalities. A meta-analysis (N = 84) was performed to estimate the pooled effect size of Motivational Interviewing (MI; primarily targeting intrinsic motivation) and contingency management (CM; primarily targeting extrinsic motivation) at different follow-up periods. Collapsed across all substance types, CM had a significant effect at 3-month follow-up, only...

INTRODUCTION: 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. METHODS: 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...

Despite the growing popularity of MDMA (ecstasy/molly) among African Americans, their motives for using the drug are still largely unknown. The purpose of this study was to identify and describe the most salient motivations for using MDMA among this understudied population. In-depth interviews (n = 15) were conducted with a sample of African American young adults in Southwest Florida between August 2014 and November 2015. The primary motivations for using MDMA included: (1) altering the effects of marijuana and alcohol; (2) lasting longer sexually; (3) enhancing sexual pleasure; and (4) facilitating "freaky" sexual experiences...

BACKGROUND AND OBJECTIVES: Although the prevalence of e-cigarette use among adolescents and young adults has caught up to or eclipsed that of combustible cigarette use, there is relatively little known about (a) the link between e-cigarettes and other substances and (b) the reasons underlying this increase in e-cigarette use. To address this gap in knowledge, the current study examined associations between e-cigarette use and other substances and identified motives for e-cigarette use among young adults...

OBJECTIVE: Given the high prevalence of marijuana use among college students, it is imperative to determine the factors that may reduce risk of problematic marijuana use and/or the development of cannabis use disorder. We examined marijuana protective behavioral strategies (PBS) as a proximal predictor of marijuana-related outcomes and a mediator of the associations between other known risk/protective factors and marijuana-related outcomes. METHOD: Using data from a sample of 2,129 past-month marijuana users, collected from 11 universities in the United States, we examined marijuana PBS use as a mediator of the effects of sex, age at first use, impulsivity-like traits, and marijuana use motives on marijuana use frequency and marijuana related consequences...

The purpose of this study was to evaluate the efficacy of the Family Check-up (FCU), a parent-focused brief motivational intervention, in families where parents were concerned about one adolescent's alcohol or marijuana use and the referred adolescent also had a sibling close in age. The primary goal of the FCU was to provide individualized feedback on specific parenting skills, including monitoring and supervision, limit setting, and alcohol-related communication. A total of 92 adolescents (37 female) between the ages of 12-19years of age along with a sibling (48 female) between the ages of 11-21years old, were randomized to the FCU or a psychoeducation (PE) comparison condition...

With several states allowing medicinal use of marijuana and a growing number decriminalizing recreational use, many of our patients are using this herbal drug. Approximately 43% of US adults have tried marijuana, with 13% using it regularly. These users are seeking help from integrative medicine practitioners regarding safety. They are looking for advice based on research and clinical experience, not politics or philosophical bias. The major health problems caused by marijuana appear to be bronchial irritation, decreased motivation, learning difficulties, and injuries...

AIMS: To test a neurobehavioral model of adolescent substance use disorder (SUD) resulting from an imbalance between a hyperactive reward motivation system and a hypoactive executive control system. Specifically, we tested (1) if early weakness in working memory (WM) and associated imbalance indicators of acting-without-thinking (AWT) and delay discounting (DD) predict SUD in late adolescence, and (2) if early drug use progression mediates this relation. DESIGN: Five waves of longitudinal data collected annually from 2005-2010, with a final follow-up in 2012...

AIMS: To examine efficacy of drug brief interventions (BIs) among adults presenting to a low income urban emergency department (ED). DESIGN: Randomized controlled trial on drug use outcomes at 3-, 6-, and 12-months. Participants were assigned to 1) computer-delivered BI (Computer BI), 2) therapist-delivered, computer-guided BI (Therapist BI), or 3) enhanced usual care (EUC-ED) for drug-using adults. Participants were re-randomized after the 3-month assessment to either adapted motivational enhancement therapy (AMET) booster; or enhanced usual care booster (EUC-B)...

INTRODUCTION: Limited research has examined reasons for polytobacco use, an increasing public health problem, particularly among young adults. We examined reasons for polytobacco use among users of more than one tobacco product in the past 4 months enrolled in an ongoing six-wave longitudinal study of 3,418 students aged 18-25 from seven US colleges and universities. METHODS: An expert panel generated items related to reasons for polytobacco use, included in Wave 3 (administered in Summer 2015)...

Given that both marijuana use and cannabis use disorder peak among college students, it is imperative to determine the factors that may reduce risk of problematic marijuana use and/or the development of cannabis use disorder. From a harm reduction perspective, the present study examined whether the use of marijuana protective behavioral strategies (PBS) buffers or amplifies the effects of several distinct risk and protective factors that have been shown to relate to marijuana-related outcomes (i.e., use frequency and consequences)...

BACKGROUND: Although marijuana is the most commonly used illicit drug in the United States, little is known about the effects of typical marijuana use patterns and whether there are distinct subgroups of marijuana users. METHODS: The present study used latent profile analysis to determine the number of distinct subgroups of marijuana users in a large sample of college students (n=2129 past month marijuana users across 11 universities). We also examined how these distinct groups differ on several putative risk/protective factors (e...

BACKGROUND: Alcohol-related blackouts are a common consequence of heavy drinking, and these blackouts pose risk for injury and other adverse health outcomes. OBJECTIVE: To examine the prevalence and correlates of blackouts among underage drinkers. METHODS: Youth (ages 14-20) presenting to a suburban Emergency Department (ED) completed screening surveys. Among those reporting past-year alcohol consumption, we examined past 3-month blackouts in relation to: background characteristics (e...

Cigarette smoking and marijuana use have been tied to increased risky sexual behaviors, which may exacerbate risk of HIV transmission and other STIs (sexually transmitted infections). Research suggests that change in general perceptions of risk is associated with change in non-domain-targeted behaviors. The goal of the current study was to determine whether change in general risk perceptions among African American college females enrolled in a culturally-tailored HIV prevention intervention would be associated with decreased cigarette and marijuana use over time...

This study examines the risk factors predicting non-prescribed stimulant use (NPSU) among adolescents, with an emphasis on whether such factors are reflective of instrumental (e.g., studying) and/or recreational (e.g., partying) drug consumption settings. Using data from Monitoring the Future (2011), we employed a series of logistic regression models to establish predictors of 12-month self-reported Adderall or Ritalin use without a doctor's note among eighth and tenth graders. Whereas studies of college students have found NPSU to correlate with instrumental motives and productivity-related demands, we find no association between NPSU and indicators of academic strain for this younger sample...

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...

BACKGROUND AND AIMS: Screening, brief intervention and 'referral to treatment' programs have been promoted widely 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 versus a no-intervention control group among primary care patients screening positive for drug use...
