Pascual, Amanda Feilding, Mayte Navarro-Gil, Javier García-Campayo and Jordi Riba Frontiers in Pharmacology, 2018, 9, 224. doi: 10.3389/fphar.2018.00224 Background : The therapeutic effects of the Amazonian plant tea ayahuasca may relate to its ability to enhance mindfulness capacities. Ayahuasca induces a modified state of awareness through the combined action of its active principles: the psychedelic N,N-dimethyltryptamine (DMT) and a series of centrally acting b-carbolines, mainly harmine and tetrahydroharmine. To better understand the therapeutic potential of [...]

Hence, we performed a meta-analysis of randomized controlled trials in order to evaluate the clinical efficacy of LSD in the treatment of alcoholism. Two reviewers independently extracted the data, pooling the effects using odds ratios (ORs) by a generic inverse variance, random effects model. We identified six eligible trials, including 536 participants. There was evidence for a beneficial effect of LSD [...]

Clinical studies suggest potential anti-addiction effects of LSD and mechanistically-related classic psychedelics for alcohol and other substance use disorders. Aims : To supplement clinical studies, reports of psychedelic use in naturalistic settings can provide further data regarding potential effects of psychedelics on alcohol use. Methods [...]
Lire la suiteCurrent perspectives on psychedelic therapy : use of serotonergic hallucinogens in clinical interventions Albert Garcia-Romeu and William A. Richards Department of Psychiatry & Behavioral Sciences, Johns Hopkins University School of Medicine, Baltimore, MD, USA INTERNATIONAL REVIEW OF PSYCHIATRY, 2018 https://doi.org/10.1080/09540261.2018.1486289 ABSTRACT Humans have used serotonergic hallucinogens (i.e. psychedelics) for spiritual, ceremonial, and recreational purposes for thousands of years, but their administration as part of a structured therapeutic intervention is still a relatively novel practice within Western medical and psychological frameworks. In the mid-20th century, considerable advances were made in developing therapeutic approaches integrating administration of low (psycholytic) and high (psychedelic) doses of serotonergic hallucinogens for treatment [...]

Alper, Dana Beal & Charles D. Kaplan I. Introduction In 1995, Dr. Curtis Wright, then the U.S. Food and Drug Administration (FDA) ibogaine project officer, wrote “What’s clear is that a significant portion of the public we serve believes the drug merits investigation” (1). Wright’s statement intimates a relationship of public opinion to regulatory scientific policy. The statement was made at a time when the FDA, partly in response to highly motivated and organized public advocacy, was modifying its drug [...]

Arran Frood Nature, 09 March 2012 doi : 10.1038/nature.2012.10200 Rights & Permissions DEA/Science Faction/Corbis An analysis of old studies suggests LSD may have a role to play in treating alcoholism. The powerful hallucinogen LSD (lysergic acid diethylamide) has potential as a treatment for alcoholism, according to a retrospective analysis of studies published in the late 1960s and early 1970s. The study1, by neuroscientist Teri Krebs and clinical psychologist Pål-Ørjan Johansen of the Norwegian University of Science and Technology in Trondheim, is the first-ever quantitative meta-analysis of LSD–alcoholism clinical trials. The researchers sifted through [...]

Des psychiatres américains explorent le potentiel thérapeutique de ces substances illicites. Par Stéphanie Chayet Engourdissement, d’abord. Puis grande fatigue, bâillements.

Le potentiel psychothérapeutique de l’acide lysergique diéthylamide est pourtant bien établi, notamment en matière de soins palliatifs, et l’on peut souhaiter que l’exploration scientifique et médicale de ce produit se développe à l’avenir. Genèse d’un médicament Printemps 1943 en Suisse, à Bâle. Albert Hoffmann, chimiste de son état, synthétise pour la compagnie Sandoz, des alcaloïdes, à partir de l’ergot de seigle. Sa recherche vise à développer de nouveaux médicaments. Alors qu’il travaille sur l’acide [...]
