Weissman ACS Pharmacology & Translational Science, 2021, 4, (2), 436-451 Doi : 10.1021/acsptsci.1c00024 Abstract Use of classic psychedelics (e.g., psilocybin, ayahuasca, lysergic acid diethylamide) is increasing and psychedelic therapy is receiving growing attention as a novel mental health intervention. Suicidality remains a potential safety concern associated with classic psychedelics and is, concurrently, a mental health concern that psychedelic therapy may show promise in targeting. Accordingly, further understanding of the relationship between classic psychedelics and suicidality is needed. Therefore, we conducted a systematic review [...]
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 [...]

Lire la suiteThe Impact of Ayahuasca on Suicidality : Results From a Randomized Controlled Trial Richard J. Zeifman, Fernanda Palhano-Fontes, Jaime Hallak, Emerson Arcoverde, João Paulo Maia-Oliveira, Draulio B. Araujo Frontiers in Pharmacology, 2019, Volume 10, Article 1325, 1-10. doi : 10.3389/fphar.2019.01325 Suicide is a major public health problem. Given increasing suicide rates and limitations surrounding current interventions, there is an urgent need for innovative interventions for suicidality. Although ayahuasca has been shown to target mental health concerns associated with suicidality (i.e., depression and hopelessness), research has not yet explored the impact of ayahuasca on suicidality. Therefore, we conducted secondary analyses of a randomized placebo-controlled trial in [...]
