Introduction:Psychedelic-assisted therapies have recently gained attention as potential novel treatments for various mental health conditions. In Canada, there has been particular interest from the veteran communities regarding the potential therapeutic impact of psychedelics. However, legal access remains limited in Canada, leading some veterans to explore alternative pathways. Here, we aimed...
Introduction:Psilocybin, a classical psychedelic, has shown to produce persistent antidepressant effects, including in patients with treatment-resistant depression. In clinical practice, it is common to coprescribe benzodiazepines (BZDs) alongside antidepressants. However, our preliminary study indicated that preadministration of lorazepam diminished the antidepressant-like efficacy and...
Background:Adverse childhood experiences (ACEs) are known to contribute to mental health issues and interfere with response to mental health interventions. Psychedelics have been found to improve mental health outcomes; however, the exploration of the effects of psychedelics on mental health in those with higher ACEs remains limited. The present study aimed to examine mental health outcomes and...
By exploring the spiritual effects of psilocybin on clergy from a range of world religions, this study widens our view to consider the full evolutionary potential of the current psychedelic revolution. Throughout human history
Griffiths et al.'s recent "Effects of Psilocybin on Religious and Spiritual Attitudes and Behaviors in Clergy from Various Major World Religions" is an important study in the literature on psychedelic medicine and religious experience. In this commentary on the study, we argue: (1) The study design's implicit presupposition of perennialism in its conception of mysticism burdens it with...
Background: Cancer poses an existential threat for patients and caregivers. Psilocybin-assisted therapy (PAT) has emerged as a potential tool to meet these existential needs, yet little is known about how patients describe this element of their cancer journey, and how it might be affected by PAT, especially in the group therapy context. Purpose: To explore how patients with cancer and...
Background: Psychedelics such as lysergic acid diethylamide (LSD) and psilocybin have shown a beneficial effect on substance use disorder (SUD) symptoms. In this systematic review, we aimed to assess the efficacy and safety of psychoactive tryptamines in patients with an SUD or non-substance-related disorder (i.e., gambling disorder) in order to provide a comprehensive overview of the available...
Mystical experiences are powerful experiences that may have therapeutic value. Ketamine, a dissociative anesthetic, has shown potential to induce mystical experiences. However, little research has explored this phenomenon, particularly in treatment-resistant depression. We analyzed clinical data from 60 veterans with treatment-resistant depression receiving a total of 189 ketamine treatments....
Prior research examining the associations between psychedelic use and general psychotic symptoms has yielded mixed findings. However, no studies have investigated the relationships between psychedelic use and specific psychotic symptoms, and whether these relationships might differ among those with liability to psychosis, namely those with a history of psychotic or bipolar disorders. Using...
Gender-themed lysergic acid diethylamide (LSD) experiences have been documented anecdotally but not yet studied systematically. This study aimed to explore such experiences using data from Reddit to better understand their nature and potential therapeutic implications. In this retrospective observational study, posts and comments on the "r/LSD" subreddit reporting gender-themed LSD experiences...
In recent years, there has been a resurgence in research exploring the therapeutic potential of psychedelics for treating mental health disorders, coinciding with increasing psychedelic use and changing legal landscapes in the United States and globally. Despite these shifts, there remains a notable gap in understanding related to the safety of psychedelic use during critical stages of the...
Black Americans are significantly underrepresented in psychedelic trials despite significant mental health disparities. Growing research suggests that psychedelic-assisted therapy (PAT) is an effective treatment for post-traumatic stress disorder and depression. It is important to understand perceptions of PAT among populations with unmet mental health needs. We conducted four focus groups to...
With several classical psychedelics being designated as breakthrough therapies and the recent review of a New Drug Application for 3,4-Methylenedioxymethamphetamine in the treatment of posttraumatic stress disorder, the likelihood of psychedelic medication becoming approved for clinical use in the United States is high. Psychedelic-assisted therapy (PAT) may have a high demand in rural America,...
Background: Although historical writings, anthropological accounts, and experimental studies document associations between psilocybin use and religion, no prospective experimental study has investigated how the effects of psilocybin are experienced and interpreted by religious clergy. This exploratory study evaluated the overall safety and the acute and enduring effects of psilocybin in clergy....
Introduction: High-dose psilocybin has shown potential in treating various psychiatric disorders, but its perceptual and cognitive effects, along with the risk of adverse events, highlight the need for alternative treatment approaches. One such approach is the use of low-dose psilocybin, which does not significantly alter cognition or perception. While low-dose psilocybin has garnered growing...
Objective: Prior research has found an association between psychedelic use and reduced stigma attached to mental illness. However, whether psychedelics alleviate stigma-related distress remains unclear. Since stigma impacts different groups uniquely, any moderating effect of psychedelics on stigma-related distress is likely to vary across subpopulations. This study addresses two main questions:...
Introduction: Ketamine is an evidenced-based treatment for depression, and it has shown promise in addressing many other mental health conditions related to work-related stress or burnout, such as anxiety and post-traumatic stress disorder. Ketamine-assisted psychotherapy (KAP) is part of an emerging model of psychedelic medicine that employs psychoactive agents to support the psychotherapeutic...
As the therapeutic potential of psychedelics is becoming more established, a wider range of compounds are beginning to be investigated for their antidepressant properties. 5-Methoxy- N , N -dimethyltryptamine (5-MeO-DMT) is one such example; its unusual properties may make it a more cost-effective and practical choice for health care providers. However, the same distinctive features may mean...
