Objective: In recent years, there has been a renewed interest in investigating the use of classic psychedelics such as psilocybin and lysergic acid diethylamide (LSD) in the treatment of mental disorders and substance use disorders. However, knowledge about the epidemiology of classic psychedelics in the Nordic countries is limited. Methods: We recruited adu...
R) agonist, are reported as effective rapid-acting antidepressants. Both compounds increase glutamate signalling and evoke cortical hyperexcitation. S-ketamine induces neurotoxicity especially in the retrosplenial cortex (Olney's lesions). Whether psilocybin produces similar neurotoxic effects has so far not been investigated. We performed an immunohistochem...
This paper explores Christian responses to religious and spiritual experiences (RSEs) associated with psilocybin-assisted therapy (PAT). It addresses the challenges of defining and understanding spiritual and religious experiences and examines the theological implications of PAT-induced RSEs. It highlights the growing acceptance of PAT as a therapeutic appro...
The present study investigated differences in perceptions of psychedelic-assisted therapy between Black and White Americans, as well as factors that may influence these perceptions. A final sample of 294 adults (42% female, 44% Black/African American or Mixed Race (of Black/African ancestry), 56% White American; Mage = 36.3 years) completed an online survey ...
There has been an increase in research on the topic of psychedelic substances and their effects as treatment options in neuropsychiatric conditions. Psilocybin is a psychedelic drug that has recently garnered increased interest as an effective treatment modality for treatment-resistant depression, depression associated with terminal conditions, certain subst...
Psychedelic-assisted treatment (PAT) for mental health is in renaissance. Psilocybin and MDMA stand near FDA approval, and US cities and states are decriminalizing or regulating the non-clinical use of psilocybin. However, neither FDA indications nor a regulated use model sufficiently address the complex needs and opportunities for an improved treatment of a...
Introduction: The classic psychedelic psilocybin, found in some mushroom species, has received renewed interest in clinical research, showing potential mental health benefits in preliminary trials. Naturalistic use of psilocybin outside of research settings has increased in recent years, though data on the public health impact of such use remain limited. Met...
Introduction: Psychedelic-assisted therapy with psilocybin has shown promise in Phase 2 trials for alcohol use disorder (AUD). Set and setting, particularly factors facilitating a connection with nature, may positively influence the psychedelic experience and therapeutic outcomes. But to date, randomized controlled trials of interventions to enhance set and ...
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...
Psychedelics as therapeutic agents have generated significant attention from clinicians and media sources in recent years. The authors provide an update to the psychiatric trainee on the evidence for psychedelics in the treatment of major depressive disorder and treatment-resistant depression. Many modern clinical trials of the classic, serotonergic psychede...
Background: Recent studies suggest that one to two administrations of psilocybin have acute antidepressant effects for people with major depressive disorder. These data on psilocybin have generated considerable enthusiasm, but little empirical attention has been paid to the therapy that adjoins psilocybin treatment (psychedelic-assisted therapy, or PAT). Mat...
This article reviews the historical protocols for the administration of “classic” psychedelics in France, from the 1920s to the 1960s. Taking a chronological approach, it investigates the way mescaline, LSD, and psilocybin were administered, the subjects involved, the route of administration, the dosage, and the epistemological context of the research. From ...
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 si...
Introduction: Psilocybin use has been linked to lowered odds of crime-related outcomes across a host of observational studies. No studies have investigated how these associations may differ among those of different races and ethnicities. Methods: Using a nationally-representative sample of 734,061 adults from the National Survey on Drug Use and Health (2002-...
Introduction: There is substantial public interest in psychedelics as potential treatments for psychiatric conditions. However, most psychedelics are criminalized under federal law in the USA, so it is unclear whether use occurs with clinical support. Our objective was to assess whether naturalistic psychedelic use occurs with clinical support, interactions ...
BACKGROUND: Pharmacological and nonpharmacological methods of inducing altered states of consciousness (ASCs) are becoming increasingly relevant in the treatment of psychiatric disorders. While comparisons between them are often drawn, to date no study has directly compared their neural correlates. METHODS: To address this knowledge gap, we directly compared...
