Psychedelic decriminalization has moved from the margins of drug-policy discourse to a mainstream public health and equity conversation. This community survey reveals that people with psychedelic experience who live in areas that have decriminalized psychedelics report greater benefits of psychedelic decriminalization than adverse outcomes. In decriminalized zones, most (84.0%) participants (N...

Most academic psychedelic research is clinically oriented, with industry research primarily focusing on the medicalization of these substances. Given the rapid policy changes and the surge in interest among researchers and the public, it is imperative to assess and document the research priorities of the broader psychedelic community. This study aimed to identify these priorities through an...

Psychedelic drugs show promise in facilitating a variety of long-term psychological changes, but they may also lead to unexpected major life changes that have not been captured by measures typically used in clinical trials. The Psychedelic-related Major Life Changes Questionnaire ( P-MLCQ ) was created to assess psychedelic-related major life changes across 10 different domains and evaluated in...

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...

BACKGROUND: The use of psychedelics is currently increasing in the United States. Awareness of clinical trials investigating the therapeutic applications of psychedelics may result in a record number of people who use psychedelics for the first-time. This study aimed to develop a harm-reduction resource to facilitate safe and successful psychedelic experiences outside of regulated clinical and...

Patients with refractory conditions often identify themselves with their illness, which affects multiple aspects of their lives. The pictorial representation of illness and self measure (PRISM) is a tool used to assess the enmeshment of individuals' perception of self with a particular medical condition, broadly termed self-condition enmeshment. This study aimed to evaluate changes in PRISM...

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...

There is a surge of interest in psychedelics, and psychedelic-assisted psychotherapy is becoming increasingly accessible. However, most individuals using psychedelics do so outside of therapeutic contexts. It is important to understand the adverse...

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.

Psychedelic drugs are currently being explored for their therapeutic potential for a variety of health conditions. The recent increased public interest in psychedelics necessitates empirical investigation into motivations for use among users as well as how motivations may change over time. We asked a large sample of participants reporting naturalistic psychedelic use (N = 1221) about their...

Introduction: In the wake of continued consumer demand despite increasing regulatory scrutiny, there is a need to develop systematic methods for identifying the harm profile of new psychoactive substances derived from hemp. Tetrahydrocannabinol-O (THC-O)-acetate, colloquially known as THCO, is the acetate ester of the principal psychoactive compound in cannabis. The heating of THCO can create...

Psychedelic-assisted therapy (PAT) has shown preliminary efficacy for psychiatric and physical health conditions. Although some people report naturalistic psychedelic use with so-called "underground" practitioners, little is known about PAT that occurs outside of controlled clinical settings or perspectives of these practitioners.

Psychedelic-assisted psychotherapy (PAP) is currently being studied as a possible treatment option for multiple disorders. Despite promising safety and efficacy findings, the high costs of the current PAP model makes it questionable if the treatment will be scalable. Non-hallucinogenic psychedelic analogs have been developed as a potential cost-effective alternative, but it is unclear what...

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...

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 between those using psychedelics and...
