Preclinical and human studies indicate psilocybin may reduce perseverant maladaptive behaviors, including nicotine and alcohol seeking. Such studies in the opioid field are lacking, though opioids are involved in more >50% of overdose deaths. Psilocybin is an agonist at the serotonin 2A receptor (5-HT2A R), a well-documented target for modulation of drug see...
Psychotherapies assisted by psychedelic substances have shown promising results in the treatment of psychiatric disorders. The aim of this systematic review and meta-analysis was to evaluate safety data in human subjects. We carried out a search on MEDLINE, Embase and PsycINFO databases between 2000 and 2022. Standardized mean differences between different d...
In vivo, psilocybin is rapidly dephosphorylated to psilocin which induces psychedelic effects by interacting with the 5-HT2A receptor. Psilocin primarily undergoes glucuronidation or conversion to 4-hydroxyindole-3-acetic acid (4-HIAA). Herein, we investigated psilocybin’s metabolic pathways in vitro and in vivo, conducting a thorough analysis of the enzymes...
The scientific claim that psychedelic drugs like psilocybin reliably occasion mystical experiences was justified using the Mystical Experiences Questionnaire (the MEQ), a survey first developed in the 1960s by Walter Pahnke using W.T. Stace’s Mysticism and Philosophy. Scholars in Christian mysticism reject the adequacy of Stace’s work for Western theistic my...
Abstract Psychological flexibility has been proposed as a core process of change when psychedelics are used for therapeutic purposes, but to date empirical outcomes have only documented changes on the Acceptance and Action Questionnaire (AAQ-II), a very general measure of psychological flexibility. This pilot study measured outcomes from psilocybin administe...
Abstract Background and aims Interest in psychedelic research has grown significantly in recent years and the naturally derived substance psilocybin, in combination with therapy, has shown promising results as a treatment for a range of psychiatric conditions. However, the negative effects and risks of psilocybin-assisted treatment are not well-established. ...
Natural psychedelics such as magic mushrooms have a long history of human use of at least 7000 years. Their use underwent a resurgence in the 1950/1960s following the synthesis of LSD as a psychedelic and its use as a medicine with powerful therapeutic benefits. But because non-medical use led to massive cultural changes especially in young people, all psych...

When Oregon's first psilocybin service center opened in June 2023, allowing those over 21 to take mind-altering mushrooms in a state-licensed facility, the psychedelic revival that had been unfolding over the past two decades entered an important new phase.Psilocybin is still illegal on the federal level. But now, as researchers explore the therapeutic poten...
ObjectiveThis study aims to provide an overview of pharmacological trials that examine the neurocognitive effects of psychedelics among healthy individuals and patients with post-traumatic stress disorder (PTSD) or major depressive disorder (MDD).MethodsThe Preferred Reporting Items for Systematic Reviews (PRISMA) was used as a guide to structure and report ...
Introduction: Amid a lack of effective chronic pain treatments, psychedelics have gained attention as a potential solution, although their Schedule 1 classification poses challenges. Psychedelics, such as lysergic acid diethylamide (LSD) and psilocybin, have gained popularity as alternatives and adjuncts for chronic pain treatment. Studies suggest that they ...
Abstract This annotated bibliography comprises 49 texts concerning psilocybin mushroom practices developed by Indigenous peoples. The books and articles have been selected for their academic rigor, relevance, and historical significance, and to foreground overlooked research and subject matter. This includes research on a plurality of contemporary practices ...
The transition of HIV into a chronic illness has brought to the forefront the pressing need to address the complex web of social determinants of HIV outcomes. A structured literature search and narrative review of studies describing intervention strategies for mental health among sexual/gender minority (SGM) older adults living with HIV (OALWH) published in ...
Do psychedelics affect sexual functioning postacutely? Anecdotal and qualitative evidence suggests they do, but this has never been formally tested. While sexual functioning and satisfaction are generally regarded as an important aspect of human wellbeing, sexual dysfunction is a common symptom of mental health disorders. It is also a common side effect of s...
Psilocybin, an innate compound produced by mushrooms belonging to the Psilocybe genus, is primarily known for its agonistic effects on the serotonin 5-HT2A receptor. This receptor’s functioning is involved in many neurological processes. In the context of this research, our primary aim was to comprehensively investigate the influence of psilocybin as a serot...
: Psychedelics are currently being examined once more as potential remedies for untreatable biological illnesses after decades of research problems. They are frequently regarded to be physically safe and do not frequently lead to dependency or addiction. The use of psychedelic substances in the treatment of mental illness and the adoption of the Substance Ac...
Psychedelics, such as psilocybin, mescaline and lysergic acid diethylamide (LSD), are psychoactive substances that induce alterations in cognition, perception and sensory processing. Studies in rodent models and healthy human volunteers highlight the serotonin 5-HT2A receptor’s pivotal role in mediating hallucinogenic effects. More recent findings indicate t...
Abstract Novel treatment strategies are needed to overcome some of the current challenges related to treatment resistance and treatment latency within the psychiatric field. Recently, psilocybin has shown promise as a novel treatment of major depressive disorder. A single dose of psilocybin is associated with lasting changes in personality and mood. In paral...
Background and Aims Psilocybin is a psychedelic drug that may hold promise for a wide range of human health conditions, yet the identification of therapeutic processes and mechanisms of action remains exploratory. We conducted a scoping review on pre-clinical behavioural investigations of psilocybin in non-human animals to help determine the behavioural effe...
