Psychedelic-assisted therapies (PATs) are emerging as novel combination treatments for selected stress- and trauma-related psychiatric conditions, particularly in cases where existing pharmacologic and psychotherapeutic approaches have provided limited benefit. Although current mechanistic models emphasize neuroplasticity, large-scale network changes, and modulation of neurotransmitter systems,...

There is currently an ongoing resurgence in research on the therapeutic potential of psychedelics for psychiatric conditions. Psychedelic-assisted therapy (PAT) differs from most current forms of psychiatric treatment in two primary domains: its requirement for fewer doses (often just one), and its documented ability to promote profound insights, introspection, and cognitive shifts. Autism...
Background: Institutional review boards (IRBs) are gatekeepers of psychedelic research, deciding whether and under what conditions it may proceed. Yet IRB understanding, attitudes, perspectives, and concerns regarding psychedelics and psychedelic research have not previously been studied. These factors are important to assessing whether US IRBs are likely to be over- or underprotective of...
Importance: The availability of psychedelic retreats has grown to meet the demand for access to these substances. Despite centuries of use among Indigenous communities, psychedelics can pose serious risks for some users. Objective: To determine safety precautions that retreat organizations that offer psychedelic substances currently use. Design, Setting, and Participants: This qualitative study...
BACKGROUND: Psychedelics such as 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin are showing promising results in clinical trials for the treatment of mental health disorders, including post-traumatic stress disorder, addiction, and treatment-resistant depression. US Food and Drug Administration approval may be on the horizon. Yet, little is known about how these treatments will move...
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...
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...
"There has been a renewed and growing interest in psychedelic drugs in the 21st century. Drawing on social-phenomenology, cognitive sociology, and ‘set and setting’ theory, I delineate how individuals use socially defined frameworks of understanding to attribute meaning to psychedelic experiences. These frameworks refer to the ‘ready-made’ schemes that structure subjective experience of...
In August 2024, The U.S. Food and Drug Administration rejected Lykos Therapeutics, Inc.'s new drug application for midomafetamine with psychological intervention (MDMA-AT) to treat post-traumatic stress disorder (PTSD). Among the many issues raised during review was concern about a highly publicized case of alleged sexual misconduct by an unlicensed therapist during a Phase 2 study of MDMA and...
OBJECTIVE: Despite growing research on the potential mental health benefits of psychedelics, there has been limited study of these drugs in populations with obsessive-compulsive disorder (OCD) and with Hispanic and Latin American (H/L) ancestry. METHODS: Demographic and clinical assessments were conducted as part of the Latin American Trans-ancestry Initiative for OCD genomics (LATINO) Study in...
Psychedelic experiences are often compared to “transformative experiences” due to their potential to change how people think and behave. This study empirically examines whether psychedelic experiences constitute transformative experiences. Given psychedelics’ prospective applications as treatments for mental health disorders, this study also explores neuroethical issues raised by the...
ABSTRACT:Psychedelics have again become a subject of widespread interest, owing to the reinvigoration of research into their traditional uses, possible medical applications, and social implications. As evidence for psychedelics' clinical potential mounts, the field has increasingly focused on searching for mechanisms to explain the effects of psychedelics and therapeutic efficacy of...
Background and aims Set and setting function both as a concept that guides research and practice with psychedelic drugs and as a meme aimed at reducing harm among psychedelic users. Referring to non-pharmacological factors that shape drug experiences, the concept of set and setting was popularized in the West during the mid-20th century. However, little theoretical development has occurred...
Psychedelic drugs, or entheogens, have been used for religious purposes among various cultures for thousands of years. Recently, these substances have caught the attention of Westerners for many reasons, including their propensity to induce mystical experiences. This study examined the relationship between religion and having mystical experiences. A total of 119 participants were drawn from...
