Reliable documentation of the traditional use of serotonergic psychedelics has long been confined to the Americas. Prevailing narratives often overstate the global prevalence and uniformity of traditional psychedelic use, extrapolating from a limited set of well-documented cases. Here, we report evidence of psilocybin mushroom use among Basotho traditional h...
The psychedelic mushroom Psilocybe cubensis is cultivated worldwide for recreational and medicinal use. Described initially from Cuba in 1906, there has been substantial debate about its origin and diversification. The prevailing view is that P. cubensis was inadvertently introduced to the Americas when cattle were introduced to the continent from Africa and...
ABSTRACT This paper examines the intimate relationship of affection, consumption, and ritual practice between humanity and mushrooms of the genus Psilocybe, focusing mainly on the Americas and Brazil. To this end, it uses reflections that present the American continent as a macroregion historically marked by transits, connections, and exchanges since pre-Col...
In the absence of specific studies on the Psilocybe genus in Italy, we provide information on the taxonomy, habitat, ecology, and distribution of the nine taxa currently recorded for Italy. A nomenclatural update of Psilocybe taxa reported in the Checklist of Italian Fungi (Basidiomycetes), published in 2005, is provided and seven scientific binomials are co...
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...
The interplay between psychedelics, such as psilocybin, lysergic acid diethylamide (LSD) and dimethyltryptamine (DMT), and sleep is an emerging area, but their impact on sleep remains relatively underexplored. This viewpoint provides a perspective on how psychedelics may alter sleep phases, dreaming, and their potential therapeutic applications for sleep dis...
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...
Hallucinogenic substances such as psilocybin, LSD or ecstasy are now the subject of several hundred clinical trials around the world to test their ability to restore our mental health. Psilocybin (active ingredient in hallucinogenic mushrooms), LSD (derived from compounds from ergot), dimethyltryptamine (or DMT, part of the composition of ayahuasca), mescali...
The ever-changing landscape surrounding legality and accessibility of psychedelics and their increasing popularity make it imperative to better understand the nature of psychedelic use by the general population. To this end, 1,486 eligible respondents (Mage = 29.58, 67.1% male) residing in the United States completed an online survey designed to assess the t...
The psychedelic experience can be challenging. There is a need for a structured framework for providing psychological support to individuals with mental health conditions receiving investigational psilocybin treatment. The primary benefit of such a framework is to support a safe and meaningful psilocybin experience. It also enables future research on the fac...
Although several studies have well described the characteristics of people who use psychedelics alongside their motivations and beliefs, little research has examined the preferences surrounding the source of psychedelic substances. In an anonymous online survey, we collected data from 6,379 consumers of 11 different psychedelic substances from 85 different c...
Background: Psychedelics such as psilocybin, lysergic acid diethylamide, and 3,4-methylenedioxymethamphetamine are increasingly recognized for their potential therapeutic benefits in treating complex and chronic mental health conditions. Growing public interest in psychedelics may drive increased consumption outside of medically supervised clinical trials. C...
Abstract Psychedelic use has increased in the last decade. However, it is unclear whether the cultural background of the consumers exerts any influence. The aim of the present study was to determine the pattern of psychedelic use in Spain and Spanish-speaking populations in South America and compare these consumption patterns to understand the use of these s...
BACKGROUND: Psychedelic drugs are increasingly visible in society once more, but their risks and adverse effects have received less attention than perhaps they should. While fatalities associated with psychedelics appear rare, a systematic approach to characterising their aetiology is required to inform harm minimisation efforts. AIMS: This study aimed to an...
BACKGROUND: Reference to an intrinsic healing mechanism or an 'inner healer' is commonplace amongst psychedelic drug-using cultures. The 'inner healer' refers to the belief that psychedelic compounds, plants or concoctions have an intrinsically regenerative action on the mind and brain, analogous to intrinsic healing mechanisms within the physical body, for ...
In this study, for the first time, we explored a dataset of functional magnetic resonance images collected during focused attention and open monitoring meditation before and after a five-day psilocybin-assisted meditation retreat using a recently established approach, based on the Mapper algorithm from topological data analysis. After generating subject-spec...
BACKGROUND: Psychedelic substances have demonstrated promise in the treatment of depression, anxiety, and substance use disorders. Significant media coverage has been dedicated to psychedelic medicine, but it is unclear whether the public associates psilocybin with its potential therapeutic benefits. The COVID-19 pandemic led to an increase in depression, an...
Magic mushrooms are fungi that produce psilocybin, a compound with breakthrough status for treatment of mental health disorders. Wood-degrading species of Psilocybe, such as P. subaeruginosa and relatives, have high concentrations of psilocybin but are discouraged for clinical production due to a temporary paralytic side effect known as Wood Lover’s Paralysi...
BackgroundThe classical psychedelics psilocybin, peyote, ayahuasca/ N, N-dimethyltryptamine, and lysergic acid diethylamide can temporarily produce altered states of consciousness, characterized by changes in sensory perception, thought, mood, and the sense of self-reality and meaning. It is important to have reliable instruments for quantifying these altere...
