Filter by: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.
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)
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.
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.
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.
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.
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.
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.
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).
The purpose of the study is to develop and test social media interventions to help young people increase well-being and reduce risky behaviors. The study will help us learn about ways to deliver wellness information in a way that is appealing and helpful to young people that use social media. Eligible participants will be enrolled after baseline survey is completed. Participants will be involved with the secret social media group they are assigned to for 8 weeks. In addition, surveys will be completed at various times during and after the 8 week social media group.
