PurposeThis paper aims to examine evolving practices and discourses surrounding psilocybin mushrooms on an online drug forum. Situating use within hybrid digital and ecological contexts, it traces shifts in user engagement before and after the 2020 COVID-19 pandemic to contextualize localized realities of the contemporary psychedelic renaissance.Design/metho...
Background: Understanding the benefits of psychedelic-assisted therapy (PAT) will require scientific attention to the causal interaction between the therapeutic context and process. Measuring what actually happens during PAT in large-scale studies will be an essential component of this work. Objective: We aim to develop and preliminarily evaluate the feasibi...
Psychedelics have robust effects on acute brain function and long-term behavior but whether they also cause enduring functional and anatomical brain changes is largely unknown. In an exploratory, placebo-controlled, within-subjects, electroencephalography (EEG), and magnetic resonance imaging (MRI) study in 28 healthy, entirely psychedelic-naive participants...
Psilocybin extends lifespan in aged mice, and this has prompted extensive media speculation about possible human longevity benefits. We examined mortality among prominent psychedelic personalities, researchers, and advocates who claimed psychedelic use (n = 11) and compared them with cancer (n = 12) and aging researchers (n = 5). All groups exceeded populati...
Abstract Background: This case describes a substance-induced manic episode with psychotic features in which interaction with an AI (artificial intelligence) chatbot appeared to corroborate and reinforce the patient’s delusional thought content and to contradict medical advice. Excerpts from the patient’s interactions with the AI chatbot provide novel clinica...
This article corrects an idea in psychedelic science and culture that the ancient Eleusynian Mysteries used psychedelics, as claimed by Carl Ruck and co-authors in (1978), revitalized by Brian Muraresku's (2020), and popularized by social media heavyweights such as Joe Rogan. It begins by exposing critical methodological flaws in the arguments, namely, a pat...
Psilocybin has been reported to decrease depression symptoms among individuals with bipolar disorder (BD), but has also been associated with reports of mania, psychosis and increased depression. With increasing recreational use of psilocybin, and the potential for psilocybin to be used as a treatment for depression, a better understanding of the risks and be...
Classic psychedelics such as psilocybin, lysergic acid diethylamide (LSD), and 5-methoxy-dimethyltryptamine (5-MeO-DMT) have shown promising effects in the treatment of certain mental health conditions. Enthusiastic claims about their therapeutic potential have led to overly optimistic reactions in the media and the public, subsequently resulting in increase...
OBJECTIVES: Interest in psilocybin as a treatment for depression has risen over the past decade, fuelled by promising clinical trials and a rapidly evolving regulatory landscape. Media coverage plays a critical role in shaping public perceptions, yet little is known about how psilocybin is portrayed in global anglophone online news for the treatment of depre...
The potential for psilocybin, and other psychedelic drugs, to fulfil a much needed and potentially transformative class of psychiatric treatments has garnered significant attention. Consequently, there has been a great deal of interest and investment in accelerating its development and potential implementation in routine clinical practice. However, the expan...
Recent advancements in the study of psilocybin and its active metabolite psilocin have highlighted their unique psychedelic properties and potential therapeutic applications, particularly in the rapid and sustained treatment of depression. However, the potent acute psychedelic effects of psilocybin necessitate a deeper understanding of the neural mechanisms ...
Conventional antidepressants show moderate efficacy in treating major depressive disorder. Psychedelic-assisted therapy holds promise, yet individual responses vary, underscoring the need for predictive tools to guide treatment selection. Here, we present graphTRIP (graph-based Treatment Response Interpretability and Prediction) - a geometric deep learning a...
The resurgence of interest in the therapeutic potential of psilocybin-producing mushrooms has recently led to numerous research and commercialization efforts. Due to its ease of cultivation and high potency, Psilocybe is the primary genus of interest, and there is a growing need to standardize maintenance, proliferation, and cultivation techniques for effici...
Importance: There is growing societal interest in and use of psilocybin. While psilocybin in Canada is illegal outside of clinical trials, there have been anecdotal reports of increasing access via unregulated online purchases and retail dispensaries. Objective: To describe access to and the characteristics of psilocybin dispensaries across Canada and the he...
INTRODUCTION: Prolonged grief disorder (PGD) represents a substantial public health issue, especially in oncology settings where it affects up to 30% of bereaved carers. Current best-practice treatments are lengthy, and up to 50% of participants have persistent PGD. Building on encouraging recent research with psychedelic-assisted therapies, the Psilocybin-A...
