Warrior CARE: Cannabis Behavioral Health

CBH
Start date: May 1, 2024
Phase: Phase 1/Phase 2
Study type: Interventional

This study is a randomized, controlled clinical trial to examine the therapeutic potential of cannabinoids for treating veterans with PTSD and suicidal ideation.

NCT ID: NCT05380583 Recruiting - Schizophrenia Clinical Trials

Community Reinforcement and Family Training for Early Psychosis (CRAFT-EP) and Substance Use: A Pilot Study

Start date: May 19, 2022
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate Community Reinforcement and Family Training for Early Psychosis (CRAFT-EP) for families experiencing early psychosis and substance use delivered exclusively or primarily via telehealth (video conferencing).

NCT ID: NCT05116527 Recruiting - Cannabis Clinical Trials

THC Memory & Reward Learning Pilot

Start date: July 7, 2022
Phase: Phase 1/Phase 2
Study type: Interventional

Tetrahydrocannabidiol (THC) is the psychoactive chemical in cannabis that makes people high. This study aims to dissect acute impairment of various forms of memory and learning by THC in cannabis compared to placebo. Impairment will be assessed via a short cognitive test battery and then subjects will complete four tasks in the fMRI scanner.

NCT ID: NCT04866004 Recruiting - HIV Infections Clinical Trials

Contingency Management for Cannabis Use for Persons With HIV

Start date: August 1, 2021
Phase: N/A
Study type: Interventional

The purpose of this study is to determine the feasibility and impact of 28-days of monitored abstinence from cannabis use on symptoms of depression and anxiety, pain, sleep, cannabis use withdrawal, HIV viral load and biomarkers of systemic inflammation among PLWH and who use cannabis regularly (weekly or more often). This will be a single arm pilot feasibility trial involving a contingency management program to induce cannabis abstinence. Specifically, the contingency management program will provide motivational (monetary) incentives to participants who achieve biochemically verified cannabis abstinence. Over the 28-days of this pilot feasibility trial, participants will attend seven study visits. During these visits, participants will complete survey questionnaires to assess sociodemographic, psychosocial, and behavioral factors. In addition, participants will provide blood and urine specimens for testing and quantitation of HIV viral load, biomarkers of systemic inflammation and for the detection of cannabis and other drugs of abuse.

NCT ID: NCT04851392 Completed - Cannabis Use Clinical Trials

Do Adolescents and Adults Differ in Their Acute Response to Cannabis?

CannTeenA
Start date: March 11, 2019
Phase: N/A
Study type: Interventional

The acute effects of cannabis may differ between adolescents and adults. Furthermore, these effects may be tempered by the presence of cannabidiol. This double-blind, placebo-controlled, crossover experiment investigates the acute effects of cannabis (with and without cannabidiol) on subjective effects, behavioural responses and neural functioning in 16-17 year-olds and 26-29 year-olds who regularly use cannabis (0.5-3 days per week).

NCT ID: NCT04587700 Completed - Cannabis Clinical Trials

Analgesic Consumption in Chronic Marijuana Users Following Orthopedic Trauma Surgery

Start date: September 21, 2020
Phase:
Study type: Observational

Marijuana use has increased since its legalization in Canada and many believe that it may help patients that are experiencing chronic pain. The investigators want to assess if patients who have used marijuana chronically will need more medication to control their pain after they have undergone orthopedic trauma surgery (ex. Hip, femur, humerus fractures etc.). In this study, the investigators will identify chronic marijuana users (ie. those using for 3 months or more) who are undergoing orthopedic trauma surgery to assess how much pain medication they need post-operatively and compare this with non-users. The investigators will also evaluate their pain scores, pain medication use and other complications that they may have during or after their surgeries, including any nausea/vomiting, heart or breathing problems.

NCT ID: NCT04495725 Completed - Chronic Pain Clinical Trials

Do Discounted Vouchers for Medical Cannabis Reduce Opioid Use in Adults With Pain

ReLeaf-V
Start date: October 6, 2020
Phase: N/A
Study type: Interventional

This study will examine how discounted vouchers for medical cannabis use affects opioid analgesic use in adults with chronic pain. Our study findings will have critically important implications to shape clinical care and medical cannabis policies.

NCT ID: NCT04308148 Completed - Chronic Pain Clinical Trials

Does Medical Cannabis Reduce Opioid Use in Adults With Pain

ReLeaf-E
Start date: October 6, 2020
Phase:
Study type: Observational

The study will examine how medical cannabis use affects opioid analgesic use. This landmark study will be among the first to examine the effect of medical cannabis with different THC/CBD (Tetrahydrocannibinol/Cannabidiol) content on opioid use as well as adverse events.

NCT ID: NCT04284813 Completed - Schizophrenia Clinical Trials

Families With Substance Use and Psychosis: A Pilot Study

Start date: September 24, 2020
Phase: N/A
Study type: Interventional

The purpose of this study is to develop and evaluate an intervention that adapts Community Reinforcement and Family Training (CRAFT) for families experiencing first episode psychosis and substance use delivered via telemedicine (video conferencing). The intervention aims to improve treatment engagement and reduce distress, and it will be delivered via telemedicine (CRAFT-FT). To assess feasibility of the intervention, family members will complete the sessions and provide feedback to refine the treatment manual. Data on client relatives with psychosis will be collected for preliminary assessment purposes. Client relatives will not complete the research study intervention.

NCT ID: NCT03699540 Completed - Alcohol Drinking Clinical Trials

Marijuana Effects on Simulated Driving Performance

Start date: July 1, 2019
Phase: Phase 1
Study type: Interventional

This study will examine the effects of various strains of marijuana on simulated driving performance; the effects of alcohol administration will also be examined to further understand how marijuana-induced driving changes compare to the effects of alcohol. Secondary outcomes will include physiological effects, subjective- and observer-rated outcomes, and psychomotor performance under the various dose conditions.
