INTRODUCTION: Interest in therapeutic applications of psychedelics has recently resurged. Mystical-type and challenging experiences that are elicited by psychedelics are commonly assessed using the 30-item Mystical Experience Questionnaire (MEQ-30) and the 26-item Challenging Experience Questionnaire (CEQ), respectively. The brief 4-item MEQ (MEQ-4) and 7-item CEQ (CEQ-7) may reduce respondent...

The revival of psychedelic medicalization is often narrated as a story of scientific legitimacy and neurotherapeutic promise, yet the unusual sensitivity of psychedelics to environmental conditions has encouraged research on music, therapy, setting, and other contextual factors. Treating setting and context as the building blocks of felt atmospheres, this article examines how regulation...

Post-treatment Lyme Disease (PTLD) is a post-infectious syndrome characterized by fatigue, hypersomnia, sleep-disturbance, musculoskeletal pain and/or cognitive difficulties. As part of an open-label pilot study of psilocybin-assisted treatment for PTLD, we explored potential for psilocybin-assisted treatment to remedy sleep-related disturbances in this population. 12 participants consented to...

Background Psilocybin has increasingly been studied as a therapeutic for psychiatric and neurologic conditions, yet comprehensive cardiovascular safety data are limited. Current trials often exclude individuals with blood pressure ≥140/90 mmHg, criteria established conservatively without robust empirical support.

To examine the prevalence of lifetime ("ever") cannabis and classic psychedelic use, and their co-use among U.S. adults aged ≥ 50 years with versus without a lifetime history of cancer, and to describe variation by cancer type/site among survivors. We analyzed pooled 2015-2019 and 2021-2022 National Survey on Drug Use and Health (NSDUH) data of U.S. adults aged ≥ 50 years (Unweighted; n =...

Importance: Annual tobacco-related death estimates are 480 000 in the US and 8 million worldwide, surpassing mortality for other abused substances. Most smoking cessation interventions result in modest long-term success. Objective: To compare prolonged smoking abstinence rates in smokers receiving psilocybin plus cognitive behavioral therapy (CBT) with those receiving the nicotine patch plus...

Abstract Lyme disease, caused by the bacterium Borrelia burgdorferi , is the most common vector-borne disease in the United States and Europe. Although antibiotics effectively treat most cases, an estimated 10–20% of patients develop post-treatment Lyme disease (PTLD), a chronic syndrome marked by fatigue, pain, cognitive difficulties, mood disturbance, and reduced quality of life. There are no...

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....

This review provides an overview of Roland R. Griffiths' history of research, and his mentoring and collaborating approach to science that contributed to his impact in behavioral and neuropsychopharmacology and psychedelic medicines development. The approach was to summarize studies in his major domains of research, including preclinical and clinical abuse liability assessment science, alcohol,...

Health-related behaviors are essential determinants of health and well-being, yet unhealthy patterns persist globally. Psychedelics may represent an innovative tool for facilitating positive behavior change. This study investigated retrospective health-related behavior changes attributed to past psychedelic experiences. An online survey was completed by 271 adults who reported on the...

Prostate cancer is the second leading cause of cancer-related deaths among U.S. men. While cannabis and classic psychedelics gain attention for symptom management in oncology, their associations with prostate cancer remain unexplored. This study evaluates associations between lifetime classic psychedelic and cannabis use with prostate cancer diagnoses among older U.S. adults using 2015-2019...

Post-traumatic stress disorder (PTSD) presents severe symptomology and often co-occurs with depression, warranting novel treatment approaches to address both conditions simultaneously. Ketamine has emerged as a rapid antidepressant and potential treatment for PTSD, with some real-world evidence for effectiveness regardless of comorbidities. The purpose of this secondary analysis was to explore...

Interest in “psychedelic therapies,” using substances such as ketamine, 3,4-methylenedioxymethamphetamine (MDMA), and psilocybin to treat psychiatric conditions, has grown steadily in recent years. Although pharmacologically distinct and functioning via differential mechanisms, these drugs are broadly classified as hallucinogenic, meaning they are thought to produce hallucinations. However,...

Ketamine has garnered attention for its rapid efficacy in alleviating depressive symptoms in treatment-resistant depression, offering a novel mechanism as a non-monoaminergic agent. Despite its potential, limited research has explored mental health professionals' perspectives on its use. This study assesses the attitudes, knowledge, and concerns of Portuguese psychiatrists and psychologists...

Abstract Introduction Research on psychedelic use and sleep satisfaction remains unclear despite increased use. This study examines the psychedelic use and sleep satisfaction among 18-to-35-year-olds enrolled in the Herbal Heart Study. Methods The exposure variables were lifetime self-reported use of any psychedelic (LSD, psilocybin, peyote, mescaline, ayahuasca/DMT) and psilocybin-alone. Sleep...

Studies of psychedelic use in naturalistic and clinical settings have suggested safety and mental health benefits for adults with histories of childhood maltreatment. Acute psychological mechanisms that predict therapeutic benefits in this population, however, have yet to be determined. Two common group settings of naturalistic psychedelic use - organized ceremonies and raves or other...

The United States Food and Drug Administration’s (FDA’s) August 2024 determination that an additional phase III study will be required to consider the approval of midomafetamine for the treatment of post-traumatic stress disorder (PTSD) could delay the potential approval of this promising treatment by several years.

The classic psychedelic psilocybin has attracted special interest across clinical and non-clinical settings as a potential tool for mental health. Despite increasing attention to challenging psychedelic experiences, few studies have explored the relevance of shame-related processes with psychedelic use. This prospective, longitudinal study involved sequential, automated, web-based surveys that...

Psilocybin (a psychoactive compound found in "magic mushrooms" or "shrooms") has been gaining increased attention in research and popular culture as a number of clinical and observational studies have demonstrated that it may have potential for improving mental wellbeing. Relatedly, there has been a substantial uptick in naturalistic (e.g., real-world, non-clinical) psilocybin use in the United...

In the context of the need to increase treatment options for substance use disorders, recent research has evaluated the therapeutic potential of psychedelics. However, there is an incomplete understanding of psychedelics' effects on craving, a core symptom of addictive disorders and a predictor of substance use and relapse. To determine if the use of psychedelics is associated with changes in...

Despite growing interest in psychedelic-assisted therapy (PAT) research, there remains a lack of consensus about key issues relevant to difficulties in predicting acute drug effects, and the role of therapeutic support in clinical trials. In the absence of a clear theoretical model to conceptualize multifaceted components in PAT research, dialogue across contexts (e.g., popular media, peer...
