I would like to remark on “Psychedelics for treating psychiatric disorders: Are they safe?” (Current Psychiatry, December 2022, p. 14-22, doi:10.12788/ cp.0309), specifically “psilocybin use has been decriminalized … and some states (such as Oregon) have legalized it for therapeutic use.
Psilocybin is a serotonergic psychedelic that has gained prominent attention recently as a potential therapeutic for neuropsychiatric disorders including Major Depressive Disorder. Pre-clinical and initial studies in humans suggest that serotonin 2A receptor agonists, including serotonergic psychedelics, have anti-inflammatory effects. This may contribute to its therapeutic effects as previous...
Psilocybin has been suggested as a novel, rapid-acting treatment for depression. Two consecutive doses have been shown to markedly decrease symptom severity in an open-label setting or when compared to a waiting list group. To date, to our knowledge, no other trial compared a single, moderate dose of psilocybin to a placebo condition. In this double-blind, randomised clinical trial, 52...
We wish to provide a correction of the colour representation of Fig. 2 in order to harmonise the colours representing the Psilocybin and the Placebo condition with the corresponding figure caption and with the colour codes from all other figures across the manuscript. Fig. 2 now depicts the Psilocybin condition in blue and the Placebo condition in yellow. The error occurred as a result of an...
Major depressive disorder (MDD), also known as clinical depression, is a serious mental disorder and ranks first among psychiatric disorders that dominate the global disease burden. Recently, it was found that psilocybin, active compound derived from psychotropic mushrooms, can relieve depression symptoms rapidly and sustained benefits for several months. Beside MDD, psilocybin can alleviate...
Abstract This article reports on integration challenges that were experienced by nine individuals who attended a three-day legal psilocybin truffle retreat in the Netherlands. The study employed a qualitative phenomenological approach, using semi-structured interviews to gain an understanding of participants' ( n = 30) psilocybin experiences and their after-effects. While the study did not...
Results from a recent Phase II trial of psilocybin-assisted therapy for treatment-resistant depression1 suggest modest efficacy but raise concerns about potential for serious adverse effects. The study highlights the need for rigorous assessment of blinding integrity, expectancy, and further study of factors that may contribute to risk in vulnerable populations.
Interest in the therapeutic potential of psilocybin across a broad range of neuropsychiatric disorders is rapidly expanding. Despite promising clinical data and tremendous public enthusiasm, complimentary basic and translational studies - which are critical for advancing our understanding of psilocybin's biological effects and promoting innovation - have been relatively few. As with all work...
Psilocybin is a psychedelic with therapeutic potential. While there is growing evidence that psilocybin exerts its beneficial effects through enhancing neural plasticity, the exact brain regions involved are not completely understood. Determining the impact of psilocybin on plasticity-related gene expression throughout the brain can broaden our understanding of the neural circuits involved in...
Abstract Aim Psilocin is an active metabolite form of psilocybin and exerts psychoactive effects. Recent studies suggest that psilocin may have regulatory effects on abuse drugs, but the mechanisms remain unclear. In this study, we want to explore the effects of psilocin on methamphetamine (METH)‐induced alterations of behavior in mice and its molecular mechanisms. Methods Acute METH...
