Cannabis Abstinence for Cannabis Use Disorder
New Haven, Connecticut
This study will be the first in vivo human multimodal neuroimaging study exploring the relationship between mGluR5 availability (PET), neural oscillations (EEG), and cognitive function in people with CUD. The goal is to test the overall hypothesis that mGluR5 availability is higher in people with CUD compared with HC. In Aim 1, the investigators will determine differences in mGluR5 availability between people with CUD and HC in the fronto-limbic brain circuit. Aim 2 examines the associations between mGluR5 availability, CUD severity, neural oscillations, and cognitive function in CUD subjects. Aim 3 will determine how prolonged abstinence from chronic cannabis use affects mGluR5 availability, neural oscillations, and cognitive function in CUD subjects.

[11C]APP311 for Cannabis Use Disorder
New Haven, Connecticut
The main purpose of this study is to determine whether hippocampal synaptic vesicle density estimated by hippocampal \[11C\]APP-311/\[11C\]UCB-J binding in individuals diagnosed with cannabis use disorder (CUDs) improves with at least 4 weeks of confirmed abstinence from cannabis, in comparison to healthy controls (HCs). Furthermore, any change in synaptic vesicle density will be placed in functional context by measuring verbal memory, which is sensitive to hippocampal function, before and after at least 4 weeks of confirmed abstinence. Finally, the relationship between hippocampal \[11C\]UCB-J binding in CUDs with measures of cannabis exposure (e.g., age of initiation, cumulative lifetime dose) will be explored.

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.

Genetics and Cannabinoid Response for Cannabis Use Disorder
West Haven, Connecticut
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.

InTEGRA vs. MET/CBT for Youth with Alcoholism and Drug Use Disorder
Farmington, Connecticut
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.

THC Testing for Cannabis Impairment
Hartford, Connecticut
This research responds to NHTSA's request with a proposal to increase our understanding of smoked cannabis' (CNB's) acute effects on driving-relevant cognition and simulated driving performance, the persistence of these deficits over the hours after use, and the influence of prior experience with CNB on these effects. This extension study will aim to further investigate marijuana impaired behavior, using a similar design to our previous NHTSA Examine the Feasibility of a Standardized Field Test for Marijuana Impairment and the prior NIDA Neuroscience of Marijuana-Impaired Driving award, that used similar techniques and measures to quantify marijuana impaired automobile driving. We will be utilizing tasks and assessments that were shown to be strong indicators for cognitive and driving impairment in our NHTSA study.

Marijuana and Alcohol Effects on Driving Impairment
Hartford, Connecticut
Alcohol and Cannabis (CNB) are two of the most widely used intoxicants. The effects of driving while intoxicated on alcohol are well documented, resulting in numerous drunken driving laws and regulations. As CNB begins to be decriminalized, medical CNB use allowed in multiple U.S. states, and perception of harmfulness falls, CNB use is predicted to rise and it will become increasingly common to publicly encounter persons who recently used the drug. An area of potentially high concern is if ever-greater numbers of CNB users and its legalization will increase the risk of driving while intoxicated from recent CNB use, thereby increasing the risks to public safety. This study aims to examine the combined effects of smoking marijuana and drinking alcohol on simulated driving.

Contingency Management for Psychosis
Montréal, Quebec
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.

Cannabis Abstinence for Cannabis Use Disorder
Minneapolis, Minnesota
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.

Medical Cannabis for Pancreatic Cancer
Saint Louis Park, Minnesota
Many patients with Pancreatic Ductal Adenocarcinoma (PDAC) experience burdensome and difficult-to-treat symptoms. The impact of multiple symptoms (called "symptom burden") can negatively affect a patient's quality of life, decrease their ability to tolerate cancer treatments, and lead to worse survival. Current approaches to manage PDAC-associated symptoms often work poorly, with most patients reporting a moderate to severe symptom burden. Therefore, there is an urgent need for treatments that improve these symptoms in patients with PDAC, and data suggests that medical cannabis can help. In this research study, we are examining the usefulness of using medical cannabis in patients with pancreatic cancer to further study how cannabis can impact their symptom burden.

Frequently Asked Questions
How much do Cannabis 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 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 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 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 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 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.
