Psychedelics have garnered great attention in recent years as treatments for major depressive disorder (MDD) and treatment-resistant depression because of their ability to alter consciousness and afflicted cognitive processes with lasting effects. We aimed to characterise how psychedelics are currently being investigated to treat substance use disorders (SUD...
Background: Self-stigma refers to the internalization of negative societal beliefs and has been associated with reduced self-efficacy, self-esteem and treatment avoidance among substance users. However, little research has explored antecedents of self-stigma such as substance use motives. This may be particularly salient for psilocybin which is used both as ...
Laws to control drugs have been progressively introduced since the early twentieth century to reduce non-medical use and drug-associated harm. Restrictions on what are now deemed ‘controlled drugs’ and, in New Zealand, ‘prohibited plants’ unjustly impact both medical care and research. The impact on research has frequently been cited in reference to the use ...
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...
Background: Psilocybin has been granted breakthrough therapy status in the United States, speeding its advancement from research to clinical care. Due to the controversial nature of psilocybin, psychiatrists may not be fully prepared to incorporate it into clinical practice. The current study aimed to evaluate the opinions toward psilocybin among practicing ...
Classic psychedelics such as lysergic acid diethylamide (LSD) and psilocybin induce mild cardiovascular activation in addition to their psychological effects. While these effects are well described in healthy adults, little is known about their dynamics in clinical populations undergoing psychedelic-assisted psychotherapy. This retrospective, observational, ...
Background Classic serotonergic psychedelics such as LSD and psilocybin show promising antidepressant effects in controlled trials, but real-world data from routine clinical care remain limited. Methods This study retrospectively analysed routine data from adults with treatment-resistant depressive and/or anxiety disorders who received a first standardized P...
Serotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. P...
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...
This retrospective observational study examines the effects of psychedelic-assisted psychotherapy (PAP) with lysergic acid diethylamide (LSD) or psilocybin in patients with treatment-resistant depressive, anxiety, or addictive disorders. Data will be analyzed from patients treated at the University Hospitals of Geneva between June 2020 and April 2025 who obt...
Introduction: Psilocybin, a serotonergic psychedelic, has shown therapeutic potential in treating mental health disorders by, amongst the many effects, promoting neuroplasticity and reorganising functional connectivity across cortical and subcortical networks involved in emotion and cognition. Veterans with traumatic brain injuries (TBI) often experience chr...
The serotonergic psychedelic psilocybin induces neural plasticity and profoundly alters consciousness. The benzodiazepine midazolam blunts neural plasticity and induces conscious sedation and amnesia at low doses. In our recent open label pilot study, we administered oral psilocybin (25 mg) along with intravenous midazolam at doses allowing a full psychedeli...
The classical psychedelics (+)-lysergic acid diethylamide (LSD), psilocybin, and mescaline exert their psychedelic effects via activation of the 5-HT2A serotonin receptor (5-HT2AR). Recent clinical studies have suggested that classical psychedelics may additionally have therapeutic potential for many neuropsychiatric conditions including depression, anxiety,...
Background: Alcohol Use Disorder (AUD) is a chronic pathological condition with significant burdens throughout the world. Despite the effectiveness of the current pharmacological treatments, the ongoing issues with AUD and the high relapse rates necessitate the exploration of innovative therapies, including the use of psychedelic drugs, which have shown prom...
A recent randomized, double-blind, placebo-controlled, parallel-group trial (NCT02061293) found that psilocybin-assisted therapy significantly improved drinking outcomes compared to an active placebo in adults with alcohol use disorder (AUD). In this secondary analysis, we assessed whether psilocybin-assisted therapy improved self-compassion and whether thes...

Background Cluster headache is an excruciating condition for which standard treatments are usually insufficient. Evidence has accumulated that serotonergic psychedelic indoleamines including psilocybin and LSD can be effective in preventing attacks. Methods In this case series, nine patients with episodic and chronic cluster headache that didn’t respond to c...
