Cannabidiol for Cannabis Use Disorder

Charleston, South Carolina
The interface between cannabis use and stress is a particularly important focus for sex differences research in emerging adults. Given the dynamics at play in this critical stage when cannabis use is most prevalent, developmentally informed research is needed to guide tailored clinical interventions. This study will apply rigorous and innovative methods to elucidate sex differences in the nexus of cannabis use and stress among emerging adults with cannabis use disorder to guide the development of tailored treatments.

The goal of this study is to test the impact of two drugs that produce temporary stress-like symptoms, both in isolation and together, on cannabis use motivation in individuals with Cannabis Use Disorder. The main questions it will answer are: 1. How do different forms of stress affect cannabis use motivation? 2. How do different forms of stress affect the body's natural cannabinoids? Researchers will compare a placebo to both drugs in isolation, as well as together, across four separate lab visits. Participants will: 1) Complete a clinical screening interview (by phone or in-person) and visit the lab for a medical screening, and if eligible: a) Visit the lab four times where they will: i). Take one of four drug combinations ii). Complete an interview, questionnaires, and computerized tasks iii). Have their brain activity recorded with an EEG cap iv). Provide three blood samples

The prevalence of daily cannabis use and Cannabis Use Disorder (CUD) has increased in the United States over the past two decades. Brief, computerized harm reduction interventions that target specific high-risk CUD populations could be an efficient approach to reducing CUD. Distress intolerance , which refers to the tendency to negatively appraise and escape aversive emotional states, is a risk factor associated with stress-related cannabis use motivation and CUD severity/chronicity. Thus, a brief, accessible, low-cost intervention that reduces distress intolerance in those with CUD and elevated distress intolerance could have a significant public health impact. This proposed project aims to optimize an existing two-session computerized distress tolerance intervention and test its impact on distress intolerance and cannabis use outcomes in a randomized controlled trial. Specifically, the intervention will be condensed to one-session, its active ingredient bolstered, and augmented with smart phone-delivered therapy reminders. After obtaining feedback on the modified Emotional Engagement Distress Tolerance Intervention in a small sample, the intervention's efficacy compared to a stringent, credible, time-matched health education control intervention will be tested in a randomized controlled trial in 80 cannabis users with CUD and high distress intolerance. Distress intolerance, cannabis use, and psychosocial functioning outcomes will be evaluated. As an exploratory aim, a wristworn device will be used to measure objective stress responding in the real-world during the intervention period. Our central hypothesis is that, compared to a control intervention, the Emotional Engagement Distress Tolerance Intervention will produce superior reductions distress intolerance, stress-related cannabis use motivation, disordered cannabis use, and psychosocial functioning.

Cannabis is widely used worldwide and is associated with negative outcomes including cannabis use disorder (CanUD), psychosis, and cognitive impairment amongst others. Given the legalization of "recreational" and "medical" cannabis globally, the increasing availability of cannabis, the higher potency of cannabis, the availability of highly potent cannabinoid products, the commercialization of cannabis, and the rising rates of cannabis use, it is critical to understand how genetic factors influence 1) an individual's vulnerability for addiction and psychosis, 2) the response to cannabinoids, 3) the response to novel treatments for CanUD. CanUD is strongly genetically influenced; the investigators published the first CanUD genomewide association study (GWAS) with genomewide-significant results; however, the precise nature of the contribution of genetic factors in the development of CanUD is still not clear. Cannabis exposure has also been linked to a number of psychosis outcomes including schizophrenia (SCZ). SCZ is highly heritable and population-based and genetics studies both support a bidirectional genetic relationship between SCZ and CanUD. However, the precise contribution of genetic factors in the development of psychosis outcomes related to cannabis are not clear.

THC for Psychosis Risk

West Haven, Connecticut
The overall purpose of this study is to determine whether a family history of psychosis is associated with an altered cannabinoid system. This will be tested by studying individuals with and without a family history of psychosis and comparing their responses to delta 9-tetrahydrocannabinol (THC), a probe of the cannabinoid system. We hypothesize, that compared to controls with no family history of psychoses, individuals with a family history of psychoses will have an altered response to THC.

This is a Phase II parallel group randomized controlled trial with 294 adolescents (age: 14-21 years) with alcohol and other drug \[AOD\] use disorder (hereafter substance use disorder), that compares two different active psychosocial interventions designed to address adolescent substance use disorder. Participants are recruited from our clinical settings and the community at two sites: one in the metro Boston, Massachusetts (MA) area and the other in the metro Farmington, Connecticut (CT), area. Study aims and hypotheses are as follows: 1. To extend the evidence for the initial efficacy of Integrated Treatment for Enhancing Growth in Recovery During Adolescence (InTEGRA), which integrates 12-Step Facilitation (TSF) with Motivational Enhancement Therapy/Cognitive Behavioral Therapy (MET/CBT) relative to gold standard MET/CBT alone (N = 294). It is hypothesized that youth assigned to InTEGRA will have greater 12-step participation during and following treatment, higher abstinence rates, and fewer substance-related negative consequences. 2. Investigate the personal recovery capital (PRC) and social recovery capital (SRC) mechanisms of behavior change through which InTEGRA may confer benefits dynamically over time (e.g., PRC: motivation, self-efficacy, coping; SRC: 12-step involvement; social network changes). 3. Investigate moderators of InTEGRA's effects on outcomes across one-year follow-up (e.g., effect of age, network support for AOD use; psychiatric severity; age composition of 12-step meetings on substance use and substance-related consequences). It is hypothesized that higher network support for AOD use, abstinence motivation, and greater AOD severity, will have a better response to InTEGRA. 4. Explore barriers and facilitators to InTEGRA adoption and implementation across providers and system administrators within the context of a type I hybrid effectiveness-implementation research design.

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.

The goal of this study is to understand the changes in neural correlates of reward in adolescents with and without Cannabis Use Disorder (CUD). The study will collect functional magnetic resonance imaging (fMRI) data at 3 different timepoints with the primary goals of understanding striatal reward-based activation during a Monetary Incentive Delay Task and fronto-striatal fMRI resting-state functional connectivity. The study will also explore self-reported impulsivity. The long-term goal is to advance scientific understanding of neural changes associated with cannabis abstinence and inter-individual variability that cannot be otherwise measured in preexisting observational cohorts such as the Adolescent Brain Cognitive Development Study. This parallel intervention study will collect fMRI data in adolescents ages 15-18 years old with and without CUD at three different timepoints over the course of their intervention. Utilizing a validated paradigm, adolescents with CUD will be randomized to 6-weeks of either incentivized, biochemically verified abstinence via contingency management or monitoring with no required abstinence. Age- and sex-matched adolescents with no lifetime history of cannabis use will also complete the protocol. Participants will complete 8 study visits (3 with fMRI scans) involving urinalysis to confirm cannabis self-report and measures of impulsivity.

Frequently Asked Questions

How much do Cannabis Use clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Cannabis Use clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Cannabis Use trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Cannabis Use is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Cannabis Use medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Cannabis Use clinical trials?

Most recently, we added Digital Intervention for Depression and Cannabis Use, Cannabis for Cognitive Impairment and THC + Beta-Myrcene Effects on Cannabis Use to the Power online platform.
