Filter by: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.
In France, consumption levels of alcohol, tobacco and cannabis remain high despite changes in regulations aimed at limiting access to these products and repeated prevention campaigns. The various Presidential Plans for the treatment and prevention of addictions for 2007-2011 and 2018-2022 show the concern of the public authorities on the issue of multiple consumption, encouraging general practitioners to identify and research this issue. In order to better identify and evaluate high-risk cannabis use, the French Observatory for Drugs and Drug Addiction has developed a detection tool: The Cannabis Abuse Screening Test (CAST). Although recommended in France, this questionnaire has never been tested in real primary care conditions, directly with patients consulting general medicine. The main objective of this study is the validation of a scale for the identification of problematic cannabis use, CAST, with a response modality according to a Likert scale (rated from 0 to 4 : 0 "never", 1 "rarely", 2 "occasionally", 3 "quite often", 4 "very often") or a binary response modality (response by 1 "Yes" or 0 "No") in patients who have used cannabis in the past 12 months, followed in general practice and in 3 age categories (15-18 years, 18-25 years and 25-45 years). The secondary objective is to analyze the polydrug use of alcohol and tobacco, and then the relationship between them and the level of cannabis use. This validation study of diagnostic scales in real-life situations with general medicine patients allows us to focus on the human and social sciences and public health. Although it has now been established that there is a synergy between several addictive substances with respect to cancer risks, few studies have focused on the early identification of misuse or polydrug use. However, it has been shown that general practitioners (GPs) are effective and relevant players in these fields. Because of their holistic vision of the patient, GPs are in the best position to identify consumers at risk of complications without blaming, dramatizing or trivializing. It is therefore necessary to provide GPs with early detection tools to promote contact between these patients and the healthcare system.
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.
The majority of the >3 million medical cannabis patients in the U.S. use cannabis products to manage pain but many questions remain. This project is designed to answer three questions that will fill important voids in the field's understanding of sustained cannabis use: 1) is abrupt cessation of cannabis associated with increased pain sensitivity; 2) does tolerance develop to the analgesic and abuse-related effects of repeatedly administered cannabis with varying ratios of THC and CBD, and is this tolerance reversible following a period of abstinence; 3) how does repeated cannabis use affect levels of endocannabinoids, and are these changes associated with changes in pain sensitivity and abuse liability? In this study, the investigators will enroll participants (N=100 healthy, cannabis-using men and non-pregnant women, ages 21-65) inpatient for 15 days. They will be randomized to one of four cannabis conditions (n=25/group). Following a day of standardization on which participants will receive their assigned cannabis condition (Day 1), cannabis will be administered repeatedly for 14 days (Day 2-15). The investigators will measure abuse-related effects ("Good Drug Effect"), endocannabinoid levels and two distinct types of experimental pain: The Cold Pressor Test and Quantitative Sensory Testing Thermal Temporal Summation. Given the widespread use of cannabis for pain, understanding the consequences of daily repeated administration of cannabis with THC:CBD ratios that are representative of most medical cannabis products on pain, abuse liability, and endocannabinoids is imperative.
This study will examine how medical cannabis use affects neuropathic pain, inflammation and adverse events in people living with HIV (PLWH) with neuropathic pain. The investigators will observe how varying ratios of THC (tetrahydrocannabinol) and CBD (cannabidiol) in medical cannabis impact neuropathic pain, inflammation and adverse events.
This study will recruit 20 women who are high risk for prenatal cannabis use for a 12-week program of using the tracker and receiving a Lifestyle Physical Activity program. The primary outcomes will be self reported percent days of cannabis use and physical activity. Secondary outcomes include self -reported measures of depression and anxiety symptoms, adaptive coping, and self-efficacy for cannabis abstinence.
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.
