The epidemiology of 5-Methoxy-N,N-Dimethyltryptamine (5-MeO-DMT) use: Benefits, consequences, patterns of use, subjective effects, and reasons for consumption Alan K. Davis, Joseph P. Barsuglia, Rafael Lancelotta, Robert M. Grant, and Elise Renn Journal of Psychopharmacology, 2018, 32, (7), 779–792. doi : 10.1177/0269881118769063 Abstract Background/Aim : 5-Methoxy-N,N-Dimethyltryptamine (5-MeO-DMT) is a psychoactive compound found in several plants and in high concentrations in Bufo alvarius toad venom. Synthetic, Toad, and Plant-sourced 5-MeO-DMT are used for spiritual and recreational purposes and may have psychotherapeutic effects. However, the use of 5-MeO-DMT is not well understood. Therefore, we examined patterns of use, motivations for consumption, subjective effects, and potential benefits and consequences [...]

Doi : 10.1371/journal.pone.0211023 Abstract The phenomenon of ‘microdosing’, that is, regular ingestion of very small quantities of psychedelic substances, has seen a rapid explosion of popularity in recent years. Individuals who microdose report minimal acute effects from these substances yet claim a range of long-term general health and wellbeing benefits. There have been no published empirical studies of microdosing and the current legal and bureaucratic climate makes direct empirical investigation of the effects of psychedelics difficult. In Study One we conducted a systematic, observational investigation of individuals [...]

Journal of Psychoactive Drugs, 2017 Doi : 10.1080/02791072.2017.1320734 Abstract Recent research suggests that functional connectivity changes may be involved in the pathophysiology of psychiatric disorders. Hyperconnectivity in the default mode network has been associated with psycho-pathology, but psychedelic serotonin agonists like psilocybin may profoundly disrupt these dysfunctional neural network circuits and provide a novel treatment for psychiatric disorders. We have reviewed the current literature to investigate the efficacy and safety of psilocybin-assisted therapy for the treatment of psychiatric disorders. There were [...]

Michael Vlessides Medscape, January 24, 2020 https://www.medscape.com/viewarticle/924202_print Patients suffering from chronic pain who take medicinal cannabis to initiate and maintain sleep appear to experience short-term benefit, but long-term use may ultimately disrupt slumber, new research shows. Investigators found whole-plant medical cannabis use was associated with fewer problems with respect to waking up at night, but they also found that frequent medical cannabis use was associated with more problems initiating and maintaining sleep. "Cannabis may improve overall sleep in the short term," study investigator Sharon Sznitman, PhD, University of Haifa Faculty of Social Welfare and Health Sciences in Israel, [...]

In an study of 90 heavy drinkers, those who received a single dose of intravenous (IV) ketamine plus cognitive behavioral therapy (CBT) that focused on reactivating drinking-related "maladaptive reward memories" (MRMs) significantly curbed the urge to drink and reduced alcohol intake compared with those who received the ketamine alone or a placebo infusion. In addition, the combination group reduced their average weekly alcohol consumption by [...]

C. Hallak BMC Psychiatry, 2019, 19, 321 https://doi.org/10.1186/s12888-019-2288-z Abstract In a recent issue of the BMC Psychiatry, the evidence of effectiveness of treatments for psychiatric conditions in end-stage cancer patients was reviewed (Johnson, 2018). The review was comprehensive, and included traditional and non-traditional/alternative treatments, including herbal medicines and spirituality. However, evidence showing that classic or serotonergic hallucinogens/psychedelics such as psilocybin and lysergic acid diethylamide (LSD) could be effective treatments for depressive and anxiety disorders in end-stage cancer was not included. In [...]
