Lire la suitePsychedelic Therapy and Suicide : A Myth Busted ? Megan Brooks Medscape Psychiatry, February 01, 2022 www.medscape.com/viewarticle/967669_print A commonly held belief that classic psychedelic therapy can trigger suicidal thoughts, actions, or other types of self-harm is not supported by research, and, in fact, the opposite may be true. Results from a meta-analysis of individual patient data showed that psychedelic therapy was associated with large, acute, and sustained decreases in suicidality across a range of clinical patient populations. "This is the first analysis to synthesize suicidality outcome data from recent clinical trials with psychedelics. It gives us a better understanding of the effects of psychedelics on suicidality in the [...]

Several state-of-the-art studies have provided new insight into the mechanisms of action of psilocybin and its therapeutic potential. Nevertheless, many questions remain unanswered. With this review, we provide an overview of the current state of research on the potential mechanisms of psilocybin, its antidepressant potential, and the associated risks [...]

MacLean Journal of Primary Care and Community Health, 2020, 11, 1-6. Doi : 10.1177/2150132720946954 Abstract Introduction : While cannabis has been medically legal in Vermont since 2004 and recreationally legal since 2018 there has been minimal published research regarding the use and practices in the adult population. This gap in understanding results in primary care providers having difficulty navigating conversations surrounding cannabinoid use. The purpose of this research was to identify current use and perceptions of cannabinoids, including Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), in adult [...]
