Psilocybin-Assisted Therapy : A Review of a Novel Treatment for Psychiatric Disorders Kelan Thomas, Pharm.D., M.S., Benjamin Malcolm, Pharm.D., M.P.H., and Dan Lastra, B.S. 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 [...]

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 [...]

Stinchcomb, and Kimberly Nixon Pharmacology, Biochemistry and Behavior, 2013, 111, 120–127. doi : 10.1016/j.pbb.2013.08.013 Abstract Excessive alcohol consumption, characteristic of alcohol use disorders, results in neurodegeneration and behavioral and cognitive impairments that are hypothesized to contribute to the chronic and relapsing nature of alcoholism. Therefore, the current study aimed to advance the preclinical development of transdermal delivery of cannabidiol (CBD) for the treatment of alcohol-induced neurodegeneration. In experiment 1, 1.0%, 2.5% and 5.0% CBD gels were evaluated for neuroprotection. [...]

It has high affinity for several serotonin receptors, including 5-HT1A, 5-HT2A, and 5-HT2C, located in numerous areas of the brain, including the cerebral cortex and thalamus. With legislation introduced in 1992, more work is being done to further understand the implications of psilocybin use in a number of disease states. Certain mental health disease states and symptoms have been studied, including [...]

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 [...]

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 [...]
