Marginalisation, stigmatisation et abandon du LSD en médecine Zoë Dubus Histoire, médecine et santé, 2019, 15, 87-105 Doi : 10.4000/hms.2168 https://journals.openedition.org/hms/2168 Abstracts Après avoir été l’une des substances pharmacologiques les plus étudiées des années 1950-1970, le LSD, puissant psychédélique ayant de nombreuses indications thérapeutiques, est abandonné par la communauté scientifique internationale au début des années 1970. Si des facteurs externes à la médecine ont eu un impact sur le déclin de ce médicament, il est également nécessaire de s’interroger sur les causes internes de ce rejet. Pour ce faire, une littérature anglo-saxonne émerge ces dernières années dans le champ des psychedelic studies, que nous enrichissons ici par une [...]

Treatment guidelines have unequivocally designated psychotherapy as a first line treatment for PTSD. Yet, even after psychotherapy, PTSD often remains a chronic illness, with high rates of psychiatric and medical comorbidity. Meanwhile, the search for and development of drugs with new mechanisms of action has stalled. Therefore, there is an urgent need to explore not [...]
Lire la suiteSynthetic and Non-synthetic Cannabinoid Drugs and Their Adverse Effects-A Review From Public Health Prospective Koby Cohen and Aviv M. Weinstein Frontiers in Public Health, 2018, Volume 6 | Article 162 doi : 10.3389/fpubh.2018.00162 There is a growing use of novel psychoactive substances containing synthetic cannabinoids. Synthetic cannabinoid products have effects similar to those of natural cannabis, yet, these drugs are more potent and dangerous, and have been associated with dangerous adverse effects. Here, we review current literature on the epidemiology, acute, and chronic effects of synthetic and natural cannabinoid-based drugs. Synthetic drugs contain a mixture of psychoactive compounds that mostly bind cannabinoid receptors with [...]

Nicholas, Chi Wing Ng, Geetanjali Deole, Zhuofan Chen and Charles L. Raison Psychological Medicine, 2020, 1–12. doi : 10.1017/S003329172000389X Abstract Background. Scientific interest in the therapeutic effects of classical psychedelics has increased in the past two decades. The psychological effects of these substances outside the period of acute intoxication have not been fully characterized. This study aimed to: (1) quantify the effects of psilocybin, ayahuasca, and lysergic acid diethylamide (LSD) on psychological outcomes in the post-acute period; (2) test moderators of these effects; and (3) evaluate [...]

DOI : 10.1097/00005053-198410000-00001 The use of naturally occurring and synthetically derived compounds for their "psychedelic" effects has been a part of human culture for thousands of years. The basic pharmacology of the major synthetic psychedelic compounds primarily lysergic acid diethylamide [LSD]-25 is described and reference is made to their potentially beneficial psychological effects. Adverse reactions, defined as dysphoric and/or maladaptive/dysfunctional responses to the use of these drugs, sometimes require careful clinical judgment in order to diagnose. These reactions [...]

KAPLAN, Christian SUEUR Annales Médico-Psychologiques, 2020, 178, 296-302 Doi : 10.16/j.amp.2020.01.018 Résumé Les usages du cannabis, en médecine et dans les traditions populaires, sont divers et anciens, ils ont été freinés depuis un siècle par la prohibition. Nous assistons depuis une trentaine d’années à un renouveau des pratiques sociales – production, distribution, usages – liées au cannabis. La découverte du système endocannabinoïde introduit un élément nouveau en faveur de l’utilisation médicale de cette plante. Les indications des cannabinoïdes en psychiatrie sont potentiellement nombreuses et demandent à être discutées. Il en va de même pour les mécanismes à l’œuvre qui restent à identifier, [...]

Lire la suitePsychedelics for Mental Illness: The Evidence to Date Todd Murphy Medscape, 12 March, 2020. https://www.medscape.com/viewarticle/926694_print Psychedelic drugs show real promise as treatment for psychiatric illnesses, particularly posttraumatic stress disorder (PTSD) as well as depression and anxiety, new research suggests. A literature review showed completed clinical trials support the efficacy of 3, 4-methylenedioxymethamphetamine (MDMA), commonly known by its street name of Ecstasy, to treat chronic PTSD. The review also confirmed that psilocybin, a compound contained in some species of mushrooms, significantly helped in the treatment of depression and cancer-related anxiety. Other promising, though more preliminary, results suggests that the hallucinogenic drug LSD (lysergic acid diethylamide) and a plant-based brew [...]
