As psychedelic use increases and integrates with mainstream medicine, understanding the prevalence and nature of postpsychedelic adverse outcomes is critical. We investigated extended difficulties after psychedelic use via the Global Psychedelic Survey (GPS) 2025, which is a multilingual online survey of people who have used psychedelics. Data on the prevalence, characteristics, and...

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...

While most psychedelic substances are considered to carry a relatively low risk of acute or long-term harm, co-use with other psychoactive substances may increase health and social harm. Using a large international survey of adults who use psychedelics, we sought to comprehensively characterize psychedelic co-use. We used data from the 2023 Global Psychedelic Survey, a web-based survey of...

People of Color have been under-included in psychedelic-assisted therapy (PAT) research. Researchers have argued that systemic issues resulting in harms to communities of color like the War on Drugs and recurrent exposure to discrimination in healthcare settings may reduce their willingness to engage in PAT research. However, there are no empirical data regarding People of Color's trust or...

Psychedelic substances have shown preliminary efficacy for several neuropsychiatric disorders and are currently being investigated for chronic pain conditions. However, few studies have investigated outcomes of naturalistic psychedelic use among individuals with chronic pain, and none have assessed psychedelic-related changes in substance use patterns in this population. In a cross-sectional...

Although several studies have well described the characteristics of people who use psychedelics alongside their motivations and beliefs, little research has examined the preferences surrounding the source of psychedelic substances. In an anonymous online survey, we collected data from 6,379 consumers of 11 different psychedelic substances from 85 different countries, exploring their preferences...

Background: The resurgent interest in psychedelic-assisted therapy for conditions like depression, end-of-life anxiety, and post-traumatic stress disorder is generating highly promising results. Within this therapeutic context, music's role is multifaceted, seen as a critical environmental component and even akin to a hidden therapist. Contemporary clinical protocols often advocate for music...

Despite psychedelic microdosing being a growing practice, the research on the topic is still in its infancy. While several studies have described the characteristics, motivations and practices of microdosers, the differences between individuals that only microdose and those that use both micro and macrodoses of psychedelics remain unexplored. In an online survey, we collected data of 6193...

Despite advancements in policies governing psychedelic substances globally, our understanding of real-world psychedelic use and its variations across international jurisdictions remains limited. We implemented the Global Psychedelic Survey (GPS) to capture information about psychedelic consumer characteristics, access, and usage patterns around the world.

Recent research suggests that psychedelics may have potential for the treatment of various substance use disorders. However, most studies to date have been limited by small sample sizes and neglecting to include non-North American and European populations. We conducted a global, cross-sectional online survey of adults (n = 5,268, 47.2% women) self-reporting past or current psychedelic use and...

This study aimed to develop and validate a short-form version of the AWE-S (AWE-SF) within psychedelic samples, to reduce participant burden while maintaining psychometric integrity. Across five studies, we first replicated the original six-factor structure of the AWE-S through exploratory and confirmatory factor analyses (Study 1), leading to the creation of the 12-item AWE-SF (Study 2-3). We...

Intimate partner violence (IPV) is a prevalent form of criminal violence that is related to externalizing pathology. However, the association between hallucinogen use and IPV has not...

This form of ayahuasca-assisted therapy appears to be associated with statistically significant improvements in several factors related to problematic substance use among a rural aboriginal population. These findings suggest participants may have experienced positive psychological and behavioral changes in response to this therapeutic approach, and that more rigorous research of...
