The majority of young adults who use alcohol and marijuana sometimes use the two substances simultaneously. Understanding why young adults engage in simultaneous alcohol and marijuana (SAM) use may inform interventions and help offset negative consequences. To date, research has not yet examined motives for SAM use. The current study tested a 26-item measure of motives for SAM use in a community sample of young adults to identify the factor structure and to evaluate associations of subscales of SAM motives with alcohol and marijuana motives and substance use...

Identifying compulsive consumption of marijuana in association with another mental disorder (attentional defcit disorder, bipolar disorder, depression or psychosis) presents the challenge of clarifying validated therapeutic strategies, especially within the teen population, in which it shows the highest prevalence. The ever-increasing prevalence and the need for regional treatments, demand that we approach this health matter as a public health issue. The ideological con?icts related to the necessary decriminalization of consumption and the current debate on the medical use of marijuana often confuse the urgent need to establish effective therapeutic strategies for the population affected by this mental disorder...

AIMS: To test the hypothesis that among non-treatment-seeking emerging adults (EA) who both use marijuana and have alcohol binges, a brief, longitudinally-delivered, developmentally-based motivational intervention would show greater reductions in the use of these two substances compared with a health education control condition. DESIGN: Parallel, two group, randomized controlled trial with follow-up interventions conducted at 1, 3, 6, and 9 months and final assessments at 12 and 15 months...

BACKGROUND: Little is known about motives for cannabis use among the population of adults using cannabis medically. Therefore, we evaluated the performance of the 12 factor, 36-item Comprehensive Marijuana Motives Questionnaire (CMMQ) among a sample of medical cannabis patients. METHODS: Study participants were adults ages 21years or older with scheduled appointments to obtain new or renewed medical cannabis certification from clinics in one Midwestern state (n=1116)...

BACKGROUND: Substance misuse is now encountered in settings beyond addiction specialty care, with schools a point-of-contact for student access to behavioral health services. Marijuana is a leading impetus for adolescent treatment admissions despite declining risk perception, for which the Teen Marijuana Check-Up (TMCU)-a tailored adaptation of motivational enhancement therapy-offers an efficacious service option. To bridge the knowledge gap concerning effective and affordable technical assistance strategies for implementing empirically supported services, the described trial will test such a strategy to facilitate school-based TMCU implementation...

BACKGROUND: Marijuana-tobacco co-use has increased recently, particularly in young adults. OBJECTIVES: We conducted a mixed-methods study to: (1) examine reasons for co-use; and (2) develop a scale assessing reasons for co-use among participants in a longitudinal cohort study of 3,418 students aged 18-25 from 7 Georgia colleges and universities. METHODS: Phone-based semi-structured interviews were conducted in Summer 2015 among 46 current (past 30-day, n = 26) or lifetime (n = 20) marijuana users...

BACKGROUND: Given increases in marijuana use and driving under the influence (DUI), it is critical to identify those at risk in order to inform intervention efforts. OBJECTIVES: We used a socioecological framework to examine correlates of level of marijuana use and DUI in the past month among young adult marijuana users. METHODS: We recruited 1567 participants aged 18-34 years via Facebook ads targeting tobacco and marijuana users in August 2014 to complete an online survey assessing marijuana use and DUI, as well as related multilevel factors...

INTRODUCTION: College students are at higher than average risk for nonmedical use of prescription stimulants (NPS). A commonly identified motive among students who engage in NPS is to improve grades. Several research studies have observed that NPS most likely does not confer an academic advantage, and is associated with excessive drinking and other drug use. This study documents the proportion of the general college student population who believe that NPS will lead to improvements in academic performance...

Motives for substance use have garnered considerable attention due to the strong predictive utility of this construct, both in terms of use and problems associated with use. The current study examined the cross-lagged relations between alcohol use and motives, and marijuana use and motives over three yearly assessment periods in a large sample (N=526, 48% male) of college students. The relations between substance use and motives were assessed at each time point, allowing for the examination of these inter-relations over time...

Firearm homicide is the leading cause of violence-related youth mortality. To inform prevention efforts, we analyzed event-level data to identify unique precursors to firearm conflicts. Youth (ages:14-24) seeking Emergency Department (ED) treatment for assault or for other reasons and reporting past 6-month drug use were enrolled in a 2-year longitudinal study. Time-line follow-back substance use/aggression modules were administered at baseline and each 6-month follow-up. Violent non-partner conflicts were combined across time-points...

BACKGROUND: Brief addiction treatments including motivational interviewing (MI) have shown promise with adolescents, but the factors that influence treatment efficacy in this population remain unknown. One candidate is working memory, the ability to hold a fact or thought in mind. This is relevant, as in therapy, a client must maintain and manipulate ideas while working with a clinician. Working memory depends upon brain structures and functions that change markedly during neurodevelopment and that can be negatively impacted by substance use...

BACKGROUND: Recent changes in marijuana policies and their potential negative effects on youth development are a public health concern. Identifying the most appropriate treatment approaches for problematic marijuana use is important. OBJECTIVES: The aim of this study was to track marijuana use among young people by examining national changes from 1995 to 2012 in the demographics, referral sources, and the substance use patterns related to youth admissions to substance abuse treatment programs...

OBJECTIVE: Concurrent use of marijuana and alcohol among college students is highly prevalent and associated with negative consequences. It remains unclear whether marijuana use is influenced by or lessens the efficacy of alcohol interventions delivered within a stepped-care approach. METHOD: Participants were 530 college students who violated campus alcohol policy and were mandated to an alcohol-focused brief advice (BA) session. Participants who reported continued risky alcohol use (4+ heavy drinking episodes and/or 5+ alcohol-related consequences in the past month) six weeks following the BA session were randomized to a brief motivational intervention (BMI; n=211) or assessment only (AO; n=194) condition...

This qualitative study examines how youth in the San Francisco Bay Area perceive marijuana and their motives for using or not using marijuana. Current regular users were more likely to perceive marijuana smoking as an enjoyable activity, comparable to a hobby or sport. Current occasional users commonly reported smoking marijuana when it was offered to them, on special occasions, and sometimes as a result of not wanting to be left out. Most former regular users reported quitting marijuana use due to getting into trouble, being ordered into drug treatment and/or being drug tested...

The marijuana amotivational syndrome posits that cannabis use fosters apathy through the depletion of motivation-based constructs such as self-efficacy. The current study pursued a two-round design to rule out concomitant risk factors responsible for the connection from marijuana intake to lower general self-efficacy. College students (N = 505) completed measures of marijuana use, demographics (age, gender, and race), personality (extraversion, agreeableness, conscientiousness, openness, and neuroticism), other substance use (alcohol and tobacco), and general self-efficacy (initiative, effort, and persistence) in two assessments separated by a month...

BACKGROUND: The present research examines anticipated consequences of ceasing or reducing marijuana use with initial development and psychometric validation of a measure of marijuana cessation expectancies. METHODS: The 46-item Marijuana Cessation Expectancies Questionnaire (MCEQ) was initially developed from the content validity analysis of free responses about expected outcomes of stopping and decreasing marijuana use generated by 94 participants. The closed-ended MCEQ was subsequently administered to 151 non-treatment seeking regular marijuana users (used on M=64...

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...
