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....
Abstract Psilocybin, a naturally occurring psychedelic compound found in certain fungi has long been used by Indigenous cultures within ritual and ceremony for healing and spiritual purposes (Spiers et al., 2024). While emerging evidence points to psychedelic agents being novel avenues for the treatment of substance use disorders, the predominantly Western medical models of psychedelic-assisted...
Naturally occurring psychoactive compounds have been used for cultural and ethnomedical purposes for centuries. Several more such molecules continue to be chemically synthesized, exhibiting a wide range of potency, therapeutic, and hallucinogenic effects. Promising clinical data and a renewed interest in understanding the cellular mechanisms of action have inspired synthetic biology efforts to...
Abstract Music is integral to Psilocybin-assisted psychotherapy (PAP), believed to enhance therapeutic outcomes by structuring experiences and facilitating emotional expression. However, the effects of conducting PAP without music are underexplored. This study examines the experiences of two breast cancer patients undergoing psilocybin therapy under Canada's compassionate access program,...
The interplay between psychedelics, such as psilocybin, lysergic acid diethylamide (LSD) and dimethyltryptamine (DMT), and sleep is an emerging area, but their impact on sleep remains relatively underexplored. This viewpoint provides a perspective on how psychedelics may alter sleep phases, dreaming, and their potential therapeutic applications for sleep disorders.
A presente tese foi dividia em dois capítulos. Capítulo I. Esse capítulo tem como objetivo investigar o possível potencial de reforço induzido pela ayahuasca por meio do paradigma de preferência condicionada por lugar (conditioned place preference, CPP), bem como avaliar se a ayahuasca é capaz de modular a CPP induzida pela cocaína durante as fases de aquisição, expressão e reinstalação da CPP...
Psychedelics offer promising outcomes in psychiatry. However, the preparation of participants (set) and the environmental conditions of taking a psychedelic (setting) are not standardized. We describe the set and setting for therapeutic use of psychedelic drugs in people with psychiatric disorders. In this systematic review, articles were identified in the PubMed and Web of Science databases...
Psychedelics have re-emerged as promising treatments for mood disorders. The current model provides a moderate-to-high dose of a psychedelic agent (e.g., psilocybin) to reliably induce an altered state of consciousness. Unfortunately, the hallucinatory effects limit the treatment's potential scalability given patients' vulnerability and extensive monitoring costs, leading to growing interest in...
This viewpoint explores the therapeutic potential of psychedelics in treating neuropsychiatric disorders, particularly through the modulation of brain entropy and the experience of ego dissolution. Psychedelics disrupt rigid neural patterns, facilitating enhanced connectivity and fostering profound emotional breakthroughs that may alleviate symptoms of disorders like depression, anxiety, PTSD,...
Despite large improvements in depressive symptoms in the psilocybin group, psilocybin therapy had only a minor effect on brain responsiveness to emotional stimuli. These results are consistent with prior findings that the antidepressant action of SSRIs is often accompanied by a reduction in emotional responsiveness, but this effect may not occur in psychedelic therapy.
Background: Opioid use disorder (OUD) is a debilitating health condition that is associated with significant morbidity and mortality in the U.S. While preliminary studies have demonstrated that psilocybin is associated with lowered odds of OUD, current research in this domain suffers from a lack of investigation into the impact of race/ethnicity on this association. Objective: To assess the...
Abstract Major depressive disorder (MDD) is a leading cause of disability that affects over 300 million people globally. Despite multiple antidepressant trials, approximately one-third of MDD patients remain symptomatic, progressing to treatment-resistant depression (TRD). This persistence possibly is due to the multifaceted etiology of TRD, encompassing biological, psychological, and...
Psychedelic therapies are promising new treatment options in psychiatry. Including the use of physical touch as part of treatment is an area of debate. This study aimed to characterize the viewpoints of practitioners on the use of touch in psychedelic therapy. An anonymous survey was distributed via e-mail to the contacts listed on ClinicalTrials.gov for trials of psilocybin and lysergic acid...
Research into psychedelics’ clinical potential has corresponded to a growth in public interest and adult use. One common pathway to accessing psychedelics is through psychedelic retreats. While individual retreats have been characterized in the anthropological literature, no systematic evaluation of the psychedelic retreat industry exists. Assessing the characteristics of the psychedelic...

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 conventional treatments were treated...

Abstract Psilocybin, a naturally occurring psychoactive compound found in more than 200 mushroom species, has an enduring history of use in sacred rituals of Indigenous healers worldwide. With selective serotonin receptor binding, activation of the serotonergic neurological system enables psilocybin to potentiate neuroplasticity, enabling individuals to engage in meaning-making from psychedelic...
Psychedelic drugs, known for their perception-altering properties, are gaining popularity in the treatment of mental health and pain disorders. As exploratory studies demonstrate clinical efficacy with few adverse events, it is expected that more patients will ingest psychedelic drugs. For therapeutic reasons, as with any drug, anaesthesiologists must be aware of its physiological effects and...
Psychedelic-assisted therapies have demonstrated promising results in treating mental disorders, with results suggesting that the subjective intensity and quality of psychedelic experiences plays a significant role in mediating therapeutic effects. However, the strength of this association across diagnoses and treatment settings remains underexplored. We searched MEDLINE, Embase, and PsycINFO...
Psychedelics are gaining attention for their therapeutic potential in modern and personalized medicine. Online forums such as Erowid provide valuable user insights, but analyses of these experiences using natural language processing (NLP) remain scarce. This study aims to utilize NLP, including sentiment and lexicon analysis, to examine user-generated experience reports on psilocybin-containing...
