Interest in psychedelic medicine is increasing, yet psychiatry trainees report limited education in this area. The authors developed a standardized curriculum and evaluated its impact on trainee knowledge and attitudes toward psychedelic medicines. A 6-h psychedelic medicine course was delivered across four psychiatry residency programs in the Northeast United States in 2025-2026. The...
There is growing evidence that psychedelics and associated treatment modalities may offer therapeutic benefits across a range of psychiatric conditions. Anorexia nervosa (AN), a serious and often treatment-resistant illness associated with significant morbidity and mortality, is one such condition for which psilocybin-assisted therapy (PAT) may hold promise. To date, research on PAT for AN has...
Psychedelics' characteristic acute subjective effects predict therapeutic benefits, such as decreases in depression and anxiety. Thus, optimizing treatment involves better understanding which factors shape subjective effects. Session facilitators, who support participants before, during, and after psychedelic administration sessions, form an important part of the setting of these experiences....
Abstract Psychedelic-assisted therapies are emerging as novel treatments of interest for a range of mental health issues, including eating disorders such as anorexia nervosa. Psychedelics, such as LSD and psilocybin, may exert biological and psychological effects pertinent to the pathophysiology of eating disorders. Initial clinical trials are underway to confirm the safety and therapeutic...
This study investigated subjective psychedelic experiences in the global LGBTQIA+ population. Using validated measures of acute psychedelic effects, psychological flexibility, gender and sexual identity attitudes, adverse experiences, and mental health, we examined self-reported changes in identity and mental health outcomes following psychedelic use. A total of 346 individuals completed the...
Current regulation frameworks for medicines struggle to address the combination of pharmacological and psychotherapeutic elements in psychedelic therapy. We propose a more appropriate and advantageous approach may be to regulate psychedelic drugs as therapeutic tools or adjuncts to psychotherapy, rather than as treatments for specific mental disorders. Drawing parallels with anesthetics, which...
Psychedelic substances exhibit complex interactions with the 'set and setting' of use, that is, the mental state of the user and the environment in which a psychedelic experience takes place. Despite these contextual variables' known importance, psychedelic research has lacked methodological rigor in reporting extra-pharmacological factors. This study aimed to generate consensus-based...
Introduction: Serotonergic psychedelics, serotonin 2A receptor agonists such as psilocybin that can result in substantially altered states of consciousness, are used in recreational and research settings. The safety of psychedelic experiences in research settings is supported by controlled physical environments, presence of clinical and medical staff to address emergent issues, screening for...
In “Distinctive but not Exceptional: The Risks of Psychedelic Ethical Exceptionalism,” Cheung et al. (2025) elaborate the ways that psychedelics share individual ethical considerations with those o...
Humans have long used classical serotonergic psychedelics, such as psilocybin, for a variety of purposes. Entactogens, such as methylenedioxymethamphetamine (MDMA), emerged during the twentieth century and have likewise seen use in a broad range of settings. Interest has arisen in the use of classical psychedelics and entactogens, together termed "psychedelics," for therapeutic purposes in...
Psychedelic-assisted therapy (PAT) with substances like psilocybin and MDMA has shown promise for conditions including depression and post-traumatic stress disorder. Psilocybin and MDMA may become approved medicines in the coming decade. This study assessed knowledge and attitudes regarding PAT among 879 U.S. healthcare professionals via anonymous online survey. Multivariable linear regression...
Psychedelic medicine is currently being evaluated for numerous mental health indications, and there is significant interest in applying these models of care to eating disorders (EDs) given the limited efficacy of available treatment models, especially for those living with anorexia nervosa. Preliminary findings across a number of studies suggest promise. In this commentary, researchers with...
OBJECTIVE: The growth of psychedelic medicine creates new challenges in psychiatric education as physicians may soon be responsible for prescribing a number of psychedelic interventions. Despite this growing need for educated providers, very little is known about the training psychiatry residents receive in psychedelic medicine. We conducted a survey to determine the current educational...
We examined if the therapeutic alliance between study participants and intervention facilitators in a psilocybin-assisted therapy (PAT) trial changed over time and whether there were relationships between alliance, acute psilocybin experiences, and depression outcomes. In a randomized, waiting list-controlled clinical trial for major depressive disorder in adults ( N = 24), participants were...

Importance Psilocybin shows promise as a treatment for major depressive disorder (MDD). Objective To evaluate the magnitude, timing, and durability of antidepressant effects and safety of a single dose of psilocybin in patients with MDD. Design, Setting, and Participants In this phase 2 trial conducted between December 2019 and June 2022 at 11 research sites in the US, participants were...
Background: Psilocybin is being studied for depression, but little is known about how it interacts with common antidepressants. Limited data suggest that psilocybin’s effects may be diminished by serotonergic antidepressants acutely and even after a medication washout period. Aims: To learn the extent to which antidepressants may diminish the effects of psilocybin-containing mushrooms both...
ABSTRACT There has been little research on the effects of psychedelics on menstrual and reproductive function, though anecdotal evidence suggests that these compounds may have striking effects on menstrual function in at least a subset of users. Social media and word of mouth were used to seek out individuals who had a history of changes in menstrual function following psychedelic use. Case...
Results from a recent Phase II trial of psilocybin-assisted therapy for treatment-resistant depression1 suggest modest efficacy but raise concerns about potential for serious adverse effects. The study highlights the need for rigorous assessment of blinding integrity, expectancy, and further study of factors that may contribute to risk in vulnerable populations.
BackgroundSubjective experiences seem to play an important role in the enduring effects of psychedelic experiences. Although the importance of the subjective experience on the impact of psychedelics is frequently discussed, a more detailed understanding of the subtypes of psychedelic experiences and their associated impacts on mental health has not been well documented.MethodsIn the current...
A growing body of research suggests psychedelic-assisted therapy (PAT) may be safe and effective for a variety of mental health conditions. Among these, eating disorders have been a recent target of interest. This review provides an up-to-date summary of the potential mechanisms and use of PAT in people diagnosed with eating disorders, with a focus on anorexia nervosa. Classic psychedelics may...

Background: Preliminary data suggest that psilocybin-assisted treatment produces substantial and rapid antidepressant effects in patients with major depressive disorder (MDD), but little is known about long-term outcomes. Aims: This study sought to examine the efficacy and safety of psilocybin through 12 months in participants with moderate to severe MDD who received psilocybin. Methods: This...
End of life and palliative care has improved in recent decades but the psychopharmacological options available to clinicians and patients in these contexts remain limited. In particular, psychological factors such as depression, existential distress, and well-being remain challenging to address with current medications. Here, we review recent research on the use of psychedelics in clinical...
