Filter by:This laboratory study will employ a multi-session experimental design to examine the behavioral economic demand for marijuana, by studying effect of marijuana administration (High THC) on demand for marijuana, and marijuana smoking topography. The study will recruit 100 non-treatment seeking marijuana users who smoke marijuana at least twice weekly.
The overall goal of this project is to collect preliminary data on psychosocial measures and behavioral performance comparing individuals with Opioid Use Disorder, Cocaine Use Disorder, dual diagnosis of Opioid and Cocaine Use Disorder, and Healthy Controls in an effort to determine overall feasibility of a phenotypic "fingerprint" for cohorts of individuals with addictions for use during clinical trials.
This trial studies attitudes about legalization of marijuana use in participants with cancer. Questionnaires may help doctors to learn about and compare the attitudes that patients in non-legalized and legalized states have towards the legalization of medical marijuana.
The purpose of this study is to evaluate the efficacy of a Substance-Free Activity Session (SFAS) as a supplement to a brief motivation intervention (BMI) in reducing marijuana use and drug-related consequences in college student
This study adapts the Public Health Service (PHS) 5As model for use with adolescent marijuana users and pilot the intervention to test feasibility and acceptability in pediatric primary care settings. The specific aims are as follows: Aim 1: Develop a marijuana screening and brief counseling intervention for adolescents based on the Public Health Service 5As model and previously developed adolescent smoking cessation intervention. Hypothesis 1: The 5As model can be adapted for use as a marijuana screening and counseling intervention for adolescents. Aim 2: Test the feasibility and acceptability of the 5As marijuana screening and brief counseling intervention in pediatric primary care practice. Hypothesis 2a: Pediatric clinicians will find the 5As intervention feasible and acceptable for addressing marijuana use in routine clinical visits with adolescents and their families; and Hypothesis 2b: Adolescents will find the 5As intervention delivered by their clinicians to be acceptable in the context of routine preventive services delivery.
A pilot trial (N=60) will be conducted to test the feasibility and preliminary effectiveness of OnTrack (a smartphone application to self-monitor substance use and sexual behaviors among homeless young adults) plus a brief motivational intervention (BMI), in comparison to treatment as usual (TAU) at Covenant House New York (CHNY) for those with substance abuse problems and who engage in risky sex. Following referral, screening, and eligibility determination, 60 participants will complete informed consent and be randomly assigned to one of two conditions: 1) TAU or 2) OnTrack + BMI. All participants will be assessed at baseline, 2 weeks, 4 weeks, and 6 weeks after baseline to evaluate alcohol consumption, marijuana use, HIV sexual risk behaviors, and other relevant variables.
The purpose of the study is to examine the comparative effectiveness of a computerized brief intervention vs. an in-person brief intervention delivered by a nurse in reducing marijuana, alcohol, and sex risk behaviors in adolescents receiving services in school-based health centers.
The investigators plan to develop and test a new alcohol and other drug (AOD) intervention for urban AI/AN youth, "Motivational Interviewing and Culture for Urban Native American Youth (MICUNAY)." This intervention integrates tradition-based activities and motivational interviewing (MI). The investigators will intervene at both the community and individual level. At the individual level, they will provide MICUNAY to adolescents. At the community level, they will provide discussion of AOD prevention at Community Wellness Gatherings (CWG). This work is important because they will gain an understanding of how well a tradition-based healing program that integrates MI works to prevent AOD use among urban AI/AN youth.
Marijuana is by far the mostly commonly used illicit drug during pregnancy, and prenatal exposure to marijuana can have lasting negative effects. However, current answers to this problem are failing to reach most women who use marijuana while pregnant. This project will develop and begin testing two technology-based, highly practical interventions that could reduce the number of children who are prenatally exposed to marijuana.
The objective of this study is to assess the effects of oral cannabidiol (CBD; 0, 200, 400, 800 mg) on smoked marijuana's (0, 5.6% THC) subjective, reinforcing, cognitive, and cardiovascular effects. This experiment is expected to reveal CBD's intrinsic effects when combined with placebo marijuana, as well as its ability to modulate the behavioral effects of active marijuana.
