The Treatment of Cannabis Use Disorder Itai Danovitch, David A. Gorelick, Chapter,The Assessment and Treatment of Addiction, january 2019 Abstract: Worldwide, cannabis is the most commonly used illicit substance. Approximately 8-12% of persons who use cannabis will develop cannabis use disorder (CUD) at some point in their life. Several psychosocial treatment methods have shown efficacy in controlled clinical trials, including motivational enhancement therapy, cognitive behavioral therapy, and contingency management. While no pharmacotherapy has been established as broadly effective for CUD, gabapentin and N-acetylcysteine have shown efficacy in single controlled clinical trials, and a number of promising approaches are under study. This article reviews established [...]

INTRODUCTION Both phytocannabinoids, the psychoactive compounds naturally present in the cannabis plant, and synthetic cannabinoids (SCs; also known as synthetic cannabimimetics) exert their effects through alteration of the endocannabinoid system (Szabo, 2014). There are at least 104 different phytocannabinoids in cannabis, and their combination contributes to the psychoactive effects of cannabis (ElSohly & Gul, 2014). In 1967, the United States [...]

Ces utilisations thérapeutiques concernaient, à l’origine, essentiellement « l’accompagnement » des psychothérapies (thérapies psycholytiques), le traitement des addictions (alcool, puis opiacés) et, du fait de leurs capacités anxiolytiques et antidépressives, la prise en charge des troubles psychologiques post-traumatiques, les dépressions résistantes, les pathologies obsessionnelles et psychosomatiques (douleurs, migraines…) et l’accompagnement des fins [...]

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2019, 8, 89, 90-96. doi: 10.1016/j.pnpbp.2018.08.030 Abstract Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication, restricted and repetitive patterns of behavior, interests, or activities and often intellectual disabilities. ASD has a number of prevalent co-morbidities, such as sleep disorders, attention deficit/hyperactivity disorder and epilepsy. No effective treatment for the core symptoms of ASD is currently available. There is increasing interest in cannabinoids, especially cannabidiol (CBD), as monotherapy or add-on treatment for the core symptoms and co-morbidities [...]

While it is well established that ASD stems from a combination of genetic and environmental factors, there are no defined mechanisms of pathogenesis, rendering curative therapy very difficult to establish. No effective therapy exists for ASD, presenting an urgent clinical need for better control of common core pathologies of ASD regardless of its etiology. Cannabidiol (CBD), a major phytocannabinoid constituent of the cannabis plant, is [...]
