Despite psilocybin still being a Schedule I substance in the Federal Controlled Substance Act (OHA, 2022), Oregon voters passed Measure 109 in 2020, now codified into law as ORS457A, which allowed for the opening of psilocybin clinics for eligible clients. The passing of Measure 109 allowed for an adult-use model to be created, which is different from a ther...
Psilocybin has emerged as a promising therapeutic agent for psychiatric and neurological disorders. However, its legal status varies significantly across countries, creating barriers for clinical use and research. This paper provides an international overview of the regulatory landscape governing medical psilocybin, highlighting key legal restrictions, polic...
We quantify cellular- and circuit-resolution neural network dynamics following therapeutically relevant doses of the psychedelic psilocybin. Using chronically implanted Neuropixels probes, we recorded local field potentials (LFP) alongside action potentials from hundreds of neurons spanning infralimbic, prelimbic and cingulate subregions of the medial prefro...
With MDMA, LSD, and psilocybin receiving “Breakthrough Therapy” designation by the U.S. Food and Drug Administration (FDA) and moving into Phase 3 clinical trials, we are closer than ever to legal administration of these compounds for mental health treatment. Research from Lykos, Usona Institute, Mindmed, Compass Pathways, and Johns Hopkins, among others, ha...
Abstract Music is integral to Psilocybin-assisted psychotherapy (PAP), believed to enhance therapeutic outcomes by structuring experiences and facilitating emotional expression. However, the effects of conducting PAP without music are underexplored. This study examines the experiences of two breast cancer patients undergoing psilocybin therapy under Canada's...
Psilocybin is an active alkaloid found in magic mushrooms (Psilocybe cubensis). It is classified as a Class I Psychoactive Substance due to its psychoactive properties. Recent research has suggested that psilocybin holds potential for treating major depressive disorder. The objective of this study was to develop a physiologically based pharmacokinetic (PBPK)...
Psilocybin, a classic psychedelic, has therapeutic potential for psychiatric disorders. A specific brain circuit and receptor have now been found to be required for psilocybin’s long-term effects on neural plasticity and depression-related behaviour. The psychedelic psilocybin’s beneficial behavioural action depends on the activation of pyramidal-tract neuro...
In recent years, there has been a significant surge of interest in psychedelic research. These studies encompass both neuroscience and their potential clinical applications. This phenomenon, often referred to as the "Psychedelic Renaissance", includes studies on compounds such as psilocybin, MDMA, DMT, and LSD used for the treatment of depression, post-traum...
The largest randomized study of psilocybin to date demonstrated the efficacy of COMP360 25 mg (Compass Pathways' investigational proprietary pharmaceutical-grade synthesized psilocybin formulation) in participants with treatment-resistant depression (COMP001), compared with 10 mg and 1 mg doses. Here, we report findings from COMP004, a 52-week observational ...
Abstract The discussion surrounding the necessity of acquiring personal experience of non-ordinary states of consciousness in the course of psilocybin-assisted therapy training is crucial, as it can affect treatment safety, effectiveness and accessibility. As such, the ethical and practical issues associated with such a training standard require timely consi...
OBJECTIVE: Unipolar and bipolar depression severely impact millions of individuals worldwide, with a significant subset of cases remaining unresponsive to conventional treatments. Psilocybin-assisted psychotherapy (PAP) has demonstrated therapeutic efficacy; however, the optimal psychotherapeutic approach remains undefined, ranging from unstructured models r...
Serotonergic psychedelics induce their characteristic subjective effects via activation of the serotonin 2A receptor (5-HT2AR). This structurally diverse class of drugs includes ergolines (e.g., LSD), phenethylamines (e.g., mescaline), and tryptamines (e.g., psilocin), all of which have NPS analogues that have emerged on recreational drug markets. Importantl...
Understanding neuromodulatory effects of serotonin 2A receptor (5-HT2A R) agonists with diverse pharmacological profiles is relevant to advancing psychedelic-related drug applications. We performed simultaneous positron emission tomography (PET) and pharmacological magnetic resonance imaging (phMRI) in anesthetized nonhuman primates (NHP; N = 3) to examine p...
OBJECTIVES: Understanding variations in knowledge and attitudes of psychiatrists to psilocybin therapy is important for the collective discourse about the potential impact on clinical practice and public health in Ireland. METHODS: A28-item questionnaire was designed based on previous studies and distributed to psychiatrists in Ireland via online mailing lis...
In visual perception, an effect known as surround suppression occurs wherein the apparent contrast of a center stimulus is reduced when it is presented within a higher-contrast surrounding stimulus. Many key aspects of visual perception involve surround suppression, yet the neuromodulatory processes involved remain unclear. Psilocybin is a serotonergic psych...
With growing research demonstrating the therapeutic potential of psychedelics such as psilocybin and MDMA in treating mental health conditions, interest is mounting around potential applications beyond health. This article explores emerging evidence on the impact of psychedelics in key domains relevant to careers and the workplace including creativity, focus...
Anorexia nervosa (AN) is a serious eating disorder (ED) with high rates of mortality and chronicity. Given the ambivalence towards engaging in treatment and recovery that is characteristic of this condition, the identification of novel treatment avenues that can target motivation and demonstrate superior efficacy to existing treatment options is desperately ...
