Filter by:A phase I, single center crossover study. The goal of this clinical trial is to learn about self-emulsified THC/CBD powder compared with equivalent dose of THC/CBD oil, orally administerd in healthy volunteers. The main question it aims to answer is: •If the pharmacokinetics profile of one dose of THC/CBD Self emulsified (S.E powder) compares to THC/CBD oil (equivalent dose). The secondary is: •If the use of THC/CBD S.E powder is tolerable and safe at least as THC/CBD oil. Participants will receive a single dose of THC/CBD S.E powder followed by a 30-day washout period and then a single dose of THC/CBD oil.
Though regulated cannabis sales are increasing, little is known about the individual health effects of cannabis regulation. Data from countries with a regulated market can be used to test the effect of regulation on the price of cannabis in the illicit market, and to explore its effect on social and health outcomes at the societal level, but strength of evidence for individual health and social outcomes is more limited because it must be aggregated on a state or country level. Data on individual and social outcomes should include baseline measurements before and outcome measurements after regulations changed. In this context, randomized-controlled trials are the least biased source of data on the effects of interventions. The SCRIPT study aims to investigate the individual health and social impact on recreational cannabis users who are allowed to purchase authorized, regulated cannabis from Swiss pharmacies compared to users who buy cannabis on the illicit market. Participants are randomly allocated in one of the two groups and followed-up for 6 months. After 6 months, all participants are allowed to participate in the intervention and the cohort is followed up for another 18 months. The intervention includes various offers: Participants can choose between cannabis sorts and delivery methods, and they are encouraged to shift from smoking cannabis to vaping cannabis-containing e-liquids, vaporizing cannabis blossoms or using oral cannabis. Vaping / vaporizing electronic devices are also recommended. At the same time, pharmacists offer opportunistic smoking cessation and problematic cannabis, alcohol use and further drug use counseling that conforms to motivational interviewing principles. The SCRIPT study adheres to rigorous quality criteria for the production and storage of regulated cannabis products. Only vaping / vaporizing electronic devices which are validated to reduce exposure to toxicants compared to cannabis smoking are recommended.
In Canada, youth ages 16-24 have the highest rates of cannabis use, impaired driving, and express the least concern for driving under the influence of cannabis (DUIC). As such, developing effective and practical DUIC prevention efforts is crucial. This study aims to evaluate the effects of 'High Alert' in reducing 3-month risky cannabis use and DUIC among young Ontarian drivers. 'High Alert' is an interactive web-based smartphone application developed by the research team with the feedback of experts and youth. 'High Alert' modules focus on recognizing what constitutes risky cannabis use, the effects of cannabis on driving, the risks of DUIC, and strategies to avoid DUIC. A pilot randomized controlled trial will compare the effects of 'High Alert' with an active control (DUIC Information) and passive control (no contact). Overall, effectively preventing DUIC among youth is critically needed and time-sensitive.
This study investigates the impact of ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD) on recognition memory in healthy, regular cannabis users. Participants complete the same recognition memory task after self-administering one of three different strains of cannabis flower one day and while not intoxicated another day. Event-related potentials (ERPs) are measured via electroencephalogram (EEG) during the recognition memory task. Blood is collected to quantify THC and CBD exposure. Participants also complete self-report measures of medical history, sleep quality, subjective cognitive function, physical activity, psychological functioning, substance use, and acute drug effects.
This research project proposes a novel approach to elucidate the biological adaptations associated with heavy cannabis use and to assess whether such adaptations are predictive of higher cannabis craving in response to both cannabis cues and stressors.
POT-GFR-PK is a single dose pharmacokinetic study oral tetrahydrocannabinol (THC) and cannabidiol (CBD) in healthy adult controls and individuals with chronic kidney disease including those treated with in-center hemodialysis.
ARISTOCRAT is a phase II, multi-centre, double-blind, placebo-controlled, randomised trial to compare the cannabinoid Nabiximols with placebo in patients with recurrent MGMT methylated glioblastoma (GBM) treated with temozolomide (TMZ).
The purpose of this study is to evaluate quantitatively and qualitatively a mobile application, Joint Effort, targeting safe cannabis use among consumers. This randomized controlled trial is currently conducted on the Joint Effort mobile application.
This study has the potential to contribute to a more complete understanding of the independent and combined effects of cannabis use and HIV on the brain and on inflammation. Such knowledge may inform future strategies for treating brain disease and inflammation. Participants will be randomly assigned to one of two groups, both of which will receive the same treatment in a different order over a period of about 6 weeks. The visits include physical examinations, blood tests, and other procedures designed to monitor subject safety and measure the effects of the study drug.
Malnutrition and inappropriate prescribing of renally excreted drugs are common among older persons and are associated with severe consequences such as complicated courses of treatment, mortality, and reduced quality of life. The overall purpose of CanPan is to optimize treatment of older persons with malnutrition with a focus on appetite stimulation and optimized prescribing of renal risk drugs. The CanPan trial consists of two sub-studies. Substudy 1 will provide knowledge on appetite and appetite stimulation and together, sub study 1 and 2 will offer unique knowledge on how body composition, renal function and biomarkers of organ function influence pharmacokinetics for a highly lipophilic (Sativex®) and hydrophilic (Hexamycin®) drug in older medical patients with malnutrition.
