NCT ID: NCT06171399 Completed - Cannabis Use Clinical Trials

Cannabis Edibles Packaging Descriptors Experiment

Start date: March 15, 2024
Phase: N/A
Study type: Interventional

The purpose of this study is to assess differences in perceptions of product appeal, harm, and subsequent willingness to try cannabis edibles products with/without product descriptors of interest.

NCT ID: NCT05566730 Completed - Cannabis Use Clinical Trials

Culturally Tailored Cannabis Use Disorder App

Start date: June 14, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05382273 Completed - Cannabis Use Clinical Trials

Cannabis Tolerance Break Resource Study: T-Break Guide

Start date: April 22, 2021
Phase:
Study type: Observational

The purpose of this pilot study is to conduct research into the value of using the T-Break Guide for assisting people taking a tolerance break from cannabis. The hope is that this initial research will yield some insights and benchmarks into the Guide's efficacy, and provide a foundation for a later randomized control study. The following are some key research questions: 1. How did participants use the Guide? (Eg: daily; read once; 'a la carte') 2. How did using the Guide increase fidelity to tolerance break (starting, continuing, completing a break)? 3. Did using the Guide yield any benefits beyond tolerance break fidelity? (Eg: insight into patterns of use)

NCT ID: NCT05328362 Completed - Cannabis Use Clinical Trials

CanCope: Digital Intervention for Coping With Cannabis Craving

Start date: August 27, 2021
Phase: N/A
Study type: Interventional

The CanCope Study is a micro-randomized trial conducted to gather evidence about and compare the effectiveness of a momentary intervention to help young adults cope with cannabis cravings as they attempt to reduce their use.

NCT ID: NCT05170217 Completed - Cannabis Use Clinical Trials

Reducing the Harmful Effects of Cannabis Use: Finding the Optimal CBD:THC Ratio

eCBD
Start date: November 8, 2017
Phase: N/A
Study type: Interventional

This study will recruit healthy volunteers who use cannabis infrequently. Each participant will attend the laboratory on five occasions: an initial visit to check that they are safe to join the study and four days of testing. Participants will be administered, in a randomized order, vaporized cannabis containing one of four different ratios of CBD:THC (0:1, 1:1, 2:1, 3:1). The cannabis administration will follow a standardised inhalation procedure using a medical-grade vaporizer device. Participants will complete a series of tasks measuring cognition, psychosis, anxiety and other subjective experiences. The study will be carried out at the NIHR-Wellcome Trust Clinical Research Facility at King's College Hospital.

NCT ID: NCT05167097 Completed - Alcohol Drinking Clinical Trials

Mindsets and the Effectiveness of a Brief Intervention - Replication

MindsetBI-R
Start date: November 8, 2021
Phase: N/A
Study type: Interventional

Brief Interventions (BI) based on Motivational Interviewing are effective in reducing alcohol use. In this study, the investigators test the hypothesis that mindsets increase the positive effects of BI among a student sample of risky drinkers. Subjects will be students with risky alcohol use as identified by the AUDIT. All participants receive the World Health Organization's (WHO) ASSIST-linked BI in one of two forms. Either with or without a decisional balance element (Steps 6-9 from the ten steps of the intervention). Before the ASSIST-linked BI, participants are randomly assigned to one of three mindset conditions. They either deliberate upon an unsolved problem (deliberative mindset), plan the implementation of a set goal (implemental mindset), or perform a control task (control condition). The investigators measure the change in alcohol-related risk perceptions, treatment motivation, and alcohol drinking as assessed via the timeline follow-back method. The investigators also assess THC consumption during the study.

NCT ID: NCT05099016 Completed - Cannabis Use Clinical Trials

Joint Effort Study

JointEffort
Start date: November 15, 2021
Phase: N/A
Study type: Interventional

This pilot randomized controlled trial (RCT) will be conducted to evaluate the acceptability and feasibility of a digital tailored prevention tool (i.e., the Joint Effort mobile application) aimed at supporting university-level students into taking action on their cannabis use. The two main objectives of the proposed study are: 1. To assess the acceptability of the Joint Effort mobile application in terms of uptake, engagement and intervention appreciation. 2. To document the feasibility of the study processes in terms of online recruitment rate, adherence to online data collection methods, and attrition rate.

NCT ID: NCT05084105 Completed - Cannabis Use Clinical Trials

Cannabis and Aging

Start date: February 1, 2020
Phase:
Study type: Observational

With increased availability and use of cannabis by older adults aged ≥ 50 years, a rigorous evaluation of the benefits and risks of cannabis use in these individuals is necessary. Our proposed project will investigate whether older adults who initiate cannabis use after the age of 50 are at an increased risk of fall and what are the underlying mechanisms. We will measure motor and cognitive function in older cannabis users and nonusers and we will use positron emission tomography to determine brain activity and how it is associated with fall risk.

NCT ID: NCT05072795 Completed - Cannabis Use Clinical Trials

Stress-Reactivity and Cannabis Use in Cannabis-Using Older Adults

PUMA
Start date: November 19, 2021
Phase: N/A
Study type: Interventional

The goal of the study is to evaluate how cannabis use affects memory and thinking skills and response to stress in older adults. The study will also relate cannabis use to Alzheimer's Disease (AD) biomarkers (measurable substances in blood that indicate condition), and test whether sex and hormones play a role in these effects. The study is recruiting adults between the ages of 50 and 80 who use cannabis products on a regular basis. Study participation will last about two weeks.

NCT ID: NCT04989205 Completed - Cannabis Use Clinical Trials

Community Based Cannabis Cessation Program

Start date: June 2, 2013
Phase:
Study type: Observational

The study examined a community based cannabis cessation program in Norway (CCP). The CCP uses a combination of cognitive therapy and psychoeducation and covers the normal withdrawal period for cannabis smoking cessation (up to 8 weeks), comprising ~15 individual sessions. From 2005 onwards, the CCP was implemented as a low-threshold community-based program in several Norwegian municipalities, e.g., Kristiansand, Fredrikstad and Oslo. The study had an observational one-group pre- / post test design. Outcomes was changes in cannabis use, mental distress, well-being, social network and sense of coherence (SoC) measured post-intervention (T2) and at a 3 months follow-up (T3).
