The investigators will follow probability-based cohorts of adult non-medical marijuana users (N=1,500; ages 21+) and susceptible adolescents and young adults (AYA) users (N=1,000; ages 15-20) over four years. The investigators will use a prospective survey to collect marijuana use information and will conduct volumetric choice experiments (VCEs) where participants choose quantities to purchase among three legal product prototypes: flower, edible, and concentrate; and one illegal flower product, under simulated retail marijuana tax structures. The presentation of edibles and concentrates will change over time to capture the range of product varieties in the market and to accommodate new products and characteristics as they evolve. Choice experiments including VCEs use a series of manipulations as a measurement device to elicit preferences for products and consumption. Therefore, the experimental design is within-subjects with repeated measures, which allow for causal identifications of the impact of design attributes (e.g., tax bases and rates) on preference and consumption outcomes. The attributes and levels are selected to reflect THC levels in the market, existing (weight, price, tiered price by forms) and novel (potency) tax bases, existing (10%-40% of retail price or equivalent in other bases) and potential (high 60% and 80% of retail prices or equivalent) tax rates, and price distribution for each product. Price distribution levels (5 to 95 percentiles) will come from our price data collection and will be updated over time and vary by participants' state and locality of residence. Before the experiment, study personnel will instruct participants 1) how to answer the choice experiment question, including considering their weekly expenditures when answering VCE questions; 2) that there is no access to other products, no stockpiling, no selling or giving away products to others, etc., to ensure that participants choose products that reflect their usual purchase patterns for self-use; 3) that there are no right or wrong responses. Study personnel will instruct participants to answer all questions honestly, thoughtfully, and to the best of their understanding as if they were actually in this situation, to reduce hypothetical bias; 4) that there may be potential costs or issues associated with purchasing illegal products, including risks of penalties, undefined potency, possible contamination, and inconsistent product quality; and 5) that participants should keep their weekly budget in mind when making purchase choices of the products. In VCEs, the investigators will manipulate THC levels, tax rates and bases, and price levels. Participants will be asked to answer the following: "Imagine these are the marijuana products that you (participants) can purchase for non-medical use, how many of each product would you (participants) most likely buy next time?" Participants can choose more than one product, and as they choose quantities, the total balance will be displayed. To make the tasks easier, study personnel will 1) set a warning to inform participants if their reported budget exceeds their weekly budget for spending; 2) provide a dropdown list for quantities or, if they would like more units than the listed, they can fill in a number; and 3) all products are described as high-quality to allow for a comparison of prices. Half of the participants will be randomized to see itemized pre-tax tag price, excise taxes, and sales taxes, as requested in some states (e.g., Illinois); the other half will be randomized to see only prices that are inclusive of excise taxes. This will allow us to whether excise taxes are more effective when applied at checkout compared to hidden in the tag prices.

e-PBI+ for College Substance Abuse

University Park, Pennsylvania
College students' risky drinking and cannabis use are major public health problems. The harms associated with risky drinking have been well-documented (such as deaths, blackouts, injuries, assaults, arrests, sexual consequences, academic consequences). Both college health administrators and parents have requested electronic parent-based interventions (e-PBIs) with additional content on cannabis. Parents have demonstrated ample motivation to communicate with their teens. The proposed research will attempt to enhance an existing effective e-PBI, curb the alarming trends noted in the literature, and move the field forward by conducting a randomized controlled trial testing a modified version of the e-PBI that includes updated content including the most up-to-date scientific information from cannabis studies (e-PBI+).

The current proposal aims to enhance a mobile-delivered brief intervention for young adults with heavy alcohol use and interpersonal trauma by including adaptive coping strategies for managing trauma-related distress and using peer coaches after delivery of the intervention to maintain treatment gains. Individuals will be randomized to a modified brief intervention incorporating with peer coaches, a standard brief intervention, or assessment only. Participants will be followed up at 3 and 6 months post intervention. The investigators hypothesize that the trauma-informed and peer-supported brief intervention (TIPS-BI) will show low levels of dropout, will be perceived positively by participants, and will result in greater reductions in alcohol use compared to a standard brief intervention and assessment only.

Cannabis is the most commonly used psychoactive substance in Canada (Lowry \& Corsi, 2020). A sub-group of cannabis users develop a condition known as Cannabis Use Disorder (CUD), which is defined as a regular pattern of cannabis use that causes performance difficulty at work, school and relationships (Hasin et al., 2013). A review of current treatments available for CUD indicate the lack of a pharmacological and psychological treatment with high success rates, which highlights the importance of exploring potential psychosocial interventions for the treatment of CUD. Given the evidence of psilocybin's therapeutic potential in the treatment of substance use disorders (de Veen et al., 2017), we aim to conduct a study using psilocybin-assisted-psychotherapy in the treatment of CUD. The study aims to evaluate the feasibility, safety, tolerability and potential therapeutic effect of 2 doses \[25 mg\] of psilocybin administered as part of an 8-week Motivational Enhancement Therapy (MET) and supportive therapy. This trial will be the first to evaluate the potential treatment effects of psilocybin on symptoms of CUD.

There is a credible basis for lateral prefrontal cortex and insula deep repetitive transcranial magnetic stimulation (dTMS) stimulation as a treatment for cannabis use disorder (CUD), but no studies to date have examined this. Evidence of benefit could expand the treatment options available for CUD but require randomized controlled trials (RCTs) to evaluate its efficacy. Toward an RCT of this intervention, the proposed study is a phase 1 open-label pilot trial of dTMS for adults with CUD. This study will establish the viability of an H4 protocol constituting an active arm of a future double-blind RCT.

There has been a considerable rise in cannabis consumption in recent years, with estimates of 200 million individual users globally. Importantly, 3% of these individuals have cannabis use disorder (CUD), with this prevalence increasing to 33% amongst regular users, making it one of the most common substances use disorders (SUDs) worldwide. CUD is associated with substantial health, societal, and economic costs, and worsening of other psychiatric disorders. Despite this clinical burden, effective treatment options are limited. No pharmacological treatments have emerged as clearly efficacious, and psychotherapeutic interventions have shown tempered results. Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain-based approach in which alternating magnetic fields are applied to the scalp to induce electrical currents in cortical tissue. As it can modulate neural circuits implicated in neuropsychiatric disorders, it is a promising brain-based approach in the treatment of addictions. Evidence has indicated its efficacy in reducing drug craving and consumption across numerous SUDs, although research into cannabis has been largely unexplored. Recently, a novel circular rTMS coil, the MagVenture MMC-140, has been developed with the capacity to modulate both the bilateral prefrontal cortex (PFC) and insula, both of which are implicated in the neurocircuitry of craving and executive function. As such, it shows potential for CUD treatment. This proof-of-concept clinical trial will evaluate the feasibility and tolerability of a 4-week course of rTMS to the PFC/insula using MMC-140 as a treatment for CUD. Feasibility of both high frequency (HF; excitatory) and low frequency (LF; inhibitory) stimulation parameters will be evaluated. In addition, pre/post rTMS changes in cannabis use outcomes (e.g., consumption, craving, and withdrawal), executive function, and PFC/insula functional connectivity will be explored. By comprehensively investigating clinical, cognitive, and neuroimaging effects of rTMS, this study could pave the way for the first brain-based intervention in CUD that could be widely adopted into clinical settings using a novel, cost-effective and accessible rTMS device.

The prevalence of major depressive disorder (MDD) is \~5.0%, and rates of co-occurring SUDs in these patients approach 40-50%. Specifically, rates of co-morbid cannabis use disorder (CUD) in patients with MDD are elevated 2-3 fold compared to 2.9% in the general population, and is associated with poorer treatment outcomes and impaired cognitive and psychosocial functioning in comparison to MDD patients without CUD. Most studies of cannabis use in MDD are cross-sectional in design, and therefore causal relationships are unclear. This study investigates the effects of cannabis abstinence over a 28-day period in patients with MDD with co-occurring CUD using a randomized controlled design, namely contingent reinforcement.

Why Other Patients Applied

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

The purpose of this research is to determine the extent to which oculomotor function accurately detects THC-impairment, if cannabis use experience impacts this detection threshold, and to examine how the oculomotor index corresponds to a measure of sustained attention. A double-blind, placebo-controlled, within-subjects crossover design will be used to examine the dose-effects of THC (0, 5mg, 30mg) on oculomotor performance tasks and a sustained attention task in frequent and infrequent cannabis users. Results from the study will advance the investigators' understanding of the effect of THC and cannabis use frequency on oculomotor function and sustained attention, and will directly inform the validity of the investigators' oculomotor platform for identifying acute THC- induced impairment in frequent and infrequent users.

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, THC + Beta-Myrcene Effects on Cannabis Use and THC for Cannabis Use to the Power online platform.
