Recent literature suggests potential associations between hallucinogen use and valvular heart disease (VHD) due to prolonged activation of serotonin 5-HT2B receptors, which may lead to valvular fibrosis - a condition also linked to drugs including fenfluramine and pergolide. Despite these concerns, epidemiological studies exploring this association are lacki...
Psilocybin-assisted therapy shows promise for depression, though current evidence relies on Phase 2 trials with notable methodological limitations. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating psilocybin-assisted therapy for major or treatment-resistant depression up to February 2024. We evaluated depre...
Psychedelic and psychedelic-adjacent substances, including 3,4-methylenedioxymethamphetamine (MDMA) and classic serotonergic hallucinogens, are undergoing renewed therapeutic investigation and remain in non-medical use. Inadvertent exposure during early, unrecognized pregnancy is clinically plausible, yet pregnancy-specific safety evidence is limited. To map...

Psychedelic Minimalism: The Case Against Music in Psychedelic Therapy SettingsIn response to: Kaelen et al. (2018), “The Hidden Therapist: Evidence for a Central Role ofMusic in Psychedelic Therapy.”Introduction: Reframing the Role of SettingIn recent years, renewed attention has been given to the centrality of set and setting inpsychedelic-assisted therapy....
BACKGROUND: Migraine and cluster headache are two primary headache disorders for which conventional treatments are limited. Classic psychedelic substances such as lysergic acid diethylamide (LSD) and psilocybin are potentially promising new treatment candidates for these conditions. AIMS: The aim of the present study was to investigate the possible relations...
Psilocybin represents a novel therapeutic approach for individuals with major depressive disorder (MDD) who do not respond to conventional antidepressant treatment. Investigating the influence of psilocybin on the pathophysiological processes involved in MDD could enhance our neurobiological understanding of the presumed antidepressant action mechanism. This...
Few population-based studies have examined associations between psychedelic use and mental health outcomes. This work describes characteristics of exclusive psychedelic mushroom use (referred to as PM use), PMs in combination with other psychedelic substances (multi-psychedelic or MP) use, and non-psychedelic use and explores mental health ratings in non-cli...
Interest in the use of serotonergic agonists such as psilocybin in treatment-resistant depression (TRD) has grown more quickly than the evidence on which to base a final opinion, as emphasized by McIntyre et al1 in their review. Psilocybin, once metabolized to psilocin, activates 5-HT2A receptors, enhancing GABA function in local circuits in the cortex and i...
Psilocybin and lysergic acid diethylamide (LSD) experiences can range from very positive to highly challenging (e.g., fear, grief, and paranoia). These challenging experiences contribute to hesitancy toward psychedelic-assisted psychotherapy among health care providers and patients. Co-use of 3,4-Methylenedioxy methamphetamine (MDMA) with psilocybin/LSD anec...
Leveraging psychedelic therapies for binge eating disorder Here Tryp Therapeutics examine the viability of using psychedelic therapies for Binge Eating Disorder and the potential results that using psychedelic-assisted psychotherapy could have on different eating disorders. Tryp Therapeutics is a clinical-stage biotechnology company dedicated to the developm...
William James proposed in 1902 that states of mystical experience, central to his idea of religious experience, can be identified based on their ineffability and their noetic quality. The epistemological category of the noetic quality, modified by W. T. Stace in 1960, plays a central but somewhat confounding role in today’s biomedical research involving psyc...
RATIONALE: Classic psychedelics are currently being studied as novel treatments for a range of psychiatric disorders. However, research on how psychedelics interact with other psychoactive substances remains scarce. OBJECTIVES: The current study aimed to explore the subjective effects of psychedelics when used alongside cannabis. METHODS: Participants (n = 3...
Introduction: There is increasing interest in the potential for psychedelic drugs such as psilocybin, LSD and ketamine to treat several mental health disorders, with a growing number of randomized controlled trials (RCTs) being conducted to investigate the therapeutic effectiveness of psychedelics.Areas covered: We review previous literature on expectancy ef...
We conducted a scoping review on psilocybin-assisted therapy for addiction, depression, anxiety and post-traumatic stress disorder. Psilocybin is a naturally-occurring tryptophan derivative found in species of mushroom with psycho-active properties. From 2022 records identified by database searching, 40 publications were included in the qualitative synthesis...
Background: The surface web is a rich source of extensive data on populations of users and misusers of psychoactive substances including substances known as hallucinogens and entheogens. The internet and its social media websites can serve as a database upon which several hypotheses are applicable via thematic analytic and psychoanalytic studies. Materials a...
Introduction: It is a basic principle of the "psychedelic" treatment model that the quality of the acute experience mediates long-term improvements in mental health. In the present paper we sought to test this using data from a clinical trial assessing psilocybin for treatment-resistant depression (TRD). In line with previous reports, we hypothesized that th...
Hallucinogen-based interventions may benefit substance use populations, but contemporary data informing the impact of hallucinogens on addictive behavior are scarce. Given that many individuals in the criminal justice system engage in problematic patterns of substance use, hallucinogen treatments also may benefit criminal justice populations. However, the re...
