Long-term effects of ayahuasca in patients with recurrent depression : a 5-year qualitative follow-up Rafael G. dos Santos, Rafael Faria Sanches, Flávia de Lima Osório, Jaime E.C. Hallak Archive of Clinical Psychiatry, 2018, 45, 1, 22-4 DOI: 10.1590/0101-60830000000149 Abstract Background : Ayahuasca is a botanical hallucinogenic preparation traditionally used by indigenous populations of Northwestern Amazonian countries for ritual and therapeutic purposes. It is rich in β-carboline alkaloids and N,N-dimethyltryptamine (DMT). Preclinical, observational, and experimental studies suggest that ayahuasca and its alkaloids have anxiolytic and antidepressive effects. We recently reported in an open-label trial that ayahuasca administration was associated with significant decreases in depression symptoms for [...]

Barker Frontiers in Neuroscience, 2018, 12, 536. doi: 10.3389/fnins.2018.00536 This report provides a historical overview of research concerning the endogenous hallucinogen N, N-dimethyltryptamine (DMT), focusing on data regarding its biosynthesis and metabolism in the brain and peripheral tissues, methods and results for DMT detection in body fluids and brain, new sites of action for DMT, and new data regarding its possible physiological and therapeutic roles. Research that further elaborates its consideration as a putative neurotransmitter is also addressed. Taking these studies together, the report [...]

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 [...]

Emphasis is given to the use of LSD by mental health professionals in the former Czechoslovakia. The text is based on four main data sources: (1) interviews with mental health professionals who experimented with LSD on themselves in the former Czechoslovakia; (2) scientific articles that were published in the time LSD research [...]
Lire la suiteAcid Diethylamide (LSD) in the Treatment of Addictions: Historical Perspectives and Future Prospects Mitchell B. Liester Current Drug Abuse Reviews, 2014, 7, 146-156 1874-4745/14 $58.00+.00 © 2014 Bentham Science Publishers Abstract : Lysergic acid diethylamide (LSD) is a semisynthetic compound with strong psychoactive properties. Chemically related to serotonin, LSD was initially hypothesized to produce a psychosislike state. Later, LSD was reported to have benefits in the treatment of addictions. However, widespread indiscriminate use and reports of adverse affects resulted in the classification of LSD as an illicit drug with no accepted medical use. This article reviews LSD’s storied history from its discovery, to its use [...]

DOI 10.3917/psyt.233.0125 https://www.cairn.info/revue-psychotropes-2017-3-page-125.htm Résumé : L’utilisation thérapeutique des substances psychédéliques a été concomitante de la découverte du LSD et de la Mescaline après la Seconde Guerre mondiale. 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 [...]
