Filter by:This study will examine the pharmacokinetics and pharmacodynamics of delta-9-tetrahydrocannabinol (THC)-infused chocolates, gummies, and drinks. Healthy adults (N=40) will complete 9 drug administration sessions, including an overnight stay prior to each session. Participants will consume THC containing products in a fasted state; following drug administration, the participants will complete cognitive and psychomotor tasks, subjective assessments, have blood collected, and vital signs monitored.
The present study aims to address disparities in cannabis use outcomes among African American/Black (hereby referred to as Black) adults with cannabis use disorder (CUD). The specific aims of this study are: (1) to develop a culturally adapted, mobile app for Black cannabis users (CT-MICART) using knowledge from the current research team, published literature, expert opinion, and feedback from the Community Research Advisory Board (CRAB), (2) to pilot test CT-MICART and (3) focus on analysis of data collected as part of Aim 2.
The Stanford Tobacco Prevention Toolkit is a free, online Toolkit that consists of a curriculum, educational resources, and a resource directory to be used by educators, parents, juvenile justice workers, and healthcare providers to increase knowledge and awareness of cannabis and reduce use among youth. The aim of this study is to investigate the extent to which the curriculum changes students' intentions to use and actual use of cannabis.
This study will examine the acute effects of cannabis on various aspects of memory. Eligible participants will complete a drug screen. Participants who pass the drug screen will be asked to wear an Empatica E4 wristband for the duration of the study. Participants will provide a saliva sample from which cortisol will be extracted. They will then complete baseline measures of cannabis consumption patterns, level of intoxication, mood, anxiety, stress, and verbal intelligence. Next, participants will be randomly assigned to inhale vapor from cannabis containing 20mg THC, 40mg THC, or placebo; both cannabis and placebo will be obtained from the National Institute on Drug Abuse (NIDA). Participants will then will complete a battery of memory tests including tests of prospective, verbal, visuospatial, source, verbal working, visuospatial working, false, and temporal order memory. Memory tests will be completed across two blocks in a counterbalanced order. Saliva samples will be obtained two additional times after drug/placebo administration. Ratings of intoxication, mood, anxiety, and stress will be obtained three additional times after drug/placebo administration. The investigators hypothesize that participants who are randomly assigned to inhale cannabis vapor will perform worse on all memory tests than participants who inhale the placebo.
The study will test a computerized treatment with subjects ages 13-17 years who are seeking treatment for alcohol and/or cannabis use. Follow-up assessments will be conducted at one- and three-months following treatment.
The aim of the study is to examine the effect of cannabis use on brain synaptic density among older adults using [11C]UCB-J PET imaging.
Cognitive impairment is well established in people with psychosis and is associated with cannabis use. The current study will investigate the neurobiological basis of cognitive change associated with 28-days of cannabis abstinence in people with psychosis and non-psychiatric controls with cannabis use. Participants will be randomized to a cannabis abstinent group or a non-abstinent control group and will undergo magnetic resonance imaging at baseline and following 28-days of abstinence. This study will help characterize the neuropathophysiological processes underlying cognitive dysfunction associated with cannabis use and its recovery which may guide the development of novel interventions for problematic cannabis use.
This study will evaluate the pharmacokinetics and pharmacodynamics of vaporized b-myrcene and THC administered via inhalation.
This project seeks to learn more about the effects of cannabis use on the endocannabinoid system and endogenous opioid systems in adolescents to address a fundamental gap in knowledge and identify biomarkers that may help distinguish youth who relapse from youth who remain sober.
This study employs a repeated measures experimental design to examine the effect of THC-dominant dose of cannabis and CBD-dominant dose of cannabis, relative to placebo, on subsequent drinking in an alcohol choice task in which participants choose either to drink or receive monetary reinforcement for drinks not consumed. Cannabis will be administered simultaneously with an alcohol-priming dose or alcohol placebo. The study will enroll up to 350 nontreatment-seeking heavy episodic alcohol drinkers who use cannabis weekly.
