Objective: Amanita muscaria mushrooms, known for their hallucinogenic effects, have grown in popularity and availability. However, use can cause delirium, coma, and death. Moreover, the US Food and Drug Administration (FDA) has stated that Amanita muscaria, its extracts, and certain constituents (muscimol, ibotenic acid, and muscarine) are unapproved additives that do not meet the Generally...
Substance use disorders (SUDs) affect the lives of more than 35 million people worldwide, according to 2019 data from the United Nations Office on Drugs and Crime. Current evidence suggests that MBIs may mitigate the harmful psychosocial effects associated with SUDs. Although MBIs have been extensively studied for efficacy, there remains a growing need to synthesize evidence from relevant...
While drug checking services can serve to minimize harms and support rapid monitoring of drug supplies to detect emerging drug trends and potential epidemics, uptake of these services is often limited. As awareness of and attitudes toward drug checking can impact uptake, the present study examined these variables and associated determinants among Australian university residential college...
BACKGROUND In the wake of cannabis legalization in Canada, daily use among young adults remains insufficiently understood. This study explores the motivations, consumption practices, and self-regulation strategies of young adults who use cannabis daily in the region of Capitale-Nationale, Québec. METHODS Forty-six individuals aged 18-34 who consume cannabis daily participated in semi-structured...
Background: Self-stigma refers to the internalization of negative societal beliefs and has been associated with reduced self-efficacy, self-esteem and treatment avoidance among substance users. However, little research has explored antecedents of self-stigma such as substance use motives. This may be particularly salient for psilocybin which is used both as a therapeutic agent and a...
Since 2000, rates of suicide and opioid overdose have sharply increased. Approximately one-third of individuals with major depressive disorder (MDD) experience treatment-resistant depression (TRD), highlighting the urgent need for novel therapeutic approaches. This review synthesizes pivotal preclinical and clinical findings on low-dose ketamine's rapid antidepressant effects and examines...
Background: Polysubstance use is common in alcohol use disorder (AUD) and associated with poor treatment outcomes. Cannabis and cocaine often co-used with alcohol, have no approved medication treatments and respond poorly to common behavioral treatments. Thus, treatments that can reduce use of these substances alongside AUD are critically needed. Objectives: We tested whether...
Venue intercept survey method detected signals of recreational cannabis, psilocybin, and cocaine use in the 20 US urban cities visited over a weekend. Reported prevalence differed by region. This suggests that prevention messaging should be tailored to the specific US regions.

Data show that recreational ketamine use appears to be increasing. This study aimed to understand how ketamine fits into broader polysubstance use in individuals with opioid use disorder (OUD). Survey data were collected from a sample of treatment-seeking individuals with OUD in March 2022. Of 301 respondents, 28.6% reported lifetime ketamine use. Ketamine use was more frequently reported among...

Drug use in Danish prisons has previously not been investigated in detail using confirmatory, laboratory analysis. The objective of the present quality study, initiated by the Danish Prison and Probation Service, was to i) evaluate the performance of an initial, on-site drug screening strategy; ii) gain insights into emerging drug trends; and iii) suggest evidence-based strategies for future...
Following the United States (U.S.) Federal Agriculture Improvement Act of 2018, many retailers began selling intoxicating cannabis products, including Delta-8 tetrahydrocannabinol (THC) as "hemp," claiming that it provided a legal loophole to do so. This qualitative study assessed Delta-8 THC messaging on YouTube, the world's second-most visited website. In 2022, two researchers searched the...
Mindfulness and Readiness to Change in Individuals with Substance Abuse: The Mediating Role of Self-Compassion and Striving to Compensate for Inferiority.
Abstract Background With increases in cannabis use and potency, there is a need to improve our understanding of the impact of use on cognitive function. Previous research indicates long-term cannabis use may have a negative effect on executive function. Few studies have examined persistence of it in protracted abstinence, and there is limited evidence of predictors of worse cognitive function...
Although studies have demonstrated that the use of lysergic acid diethylamide (LSD) is on the rise in the United States, it remains unclear how this trend looks across the hierarchical ladder of the American workforce. This is relevant given that LSD is increasingly being touted as a means of boosting creativity and performance, with mounting anecdotal evidence that business managers in...
Background: Globally, street-involved children and youth (SICY) who work and live on/of the streets are at higher risk of increased psychoactive substances and injecting drug use. Objectives: The present study aimed to identify the prevalence, distribution, sociodemographic factors, and risk-taking behaviors associated with psychoactive substances and injecting drug use among SICY. Methods:...

Background: Opioid overdose deaths in the U.S. continue to increase, largely due to the prevalence of fentanyl, a very powerful opioid, in the illicit drug supply. Buprenorphine treatment is effective for treating opioid use disorder, but it can be challenging for clinicians to introduce buprenorphine treatment to people who use fentanyl due to risks of precipitated withdrawal. Induction could...
Background: Preliminary evidence suggests that long-term ayahuasca use is associated with better psychosocial outcomes and less drug use; however, available data on the association between ayahuasca intake frequency and psychosocial outcomes is limited. Objectives: We sought to characterize and investigate the association of regular ayahuasca use, as compared to non-regular use, on licit...
Background: Adolescent cannabis use is an established risk factor for the development of psychosis, but the premorbid vulnerability factors and specificity versus generality of the psychotic symptom domains affected in cannabis-psychosis relationships remain incompletely understood. To improve our understanding of these relationships, we used longitudinal data to examine the individual and...
3,4-Methylenedioxy-N-methylamphetamine (MDMA) is increasing being used by youth in Europe and in France, but characteristics of its use are unknown. Objectives: The aim was to characterize MDMA use in a sample of French medical students. Methods: Cross-sectional study of Paris VII medical students (N = 592) with an online self-reporting questionnaire. Results: 592 students completed the online...
Ecstasy (MDMA, Molly) is among the most prevalent drugs used by people who attend electronic dance music (EDM) events; however, little recent research has examined diffusion of ecstasy in this high-risk population. Methods: 1,020 EDM event-attending adults (aged 18-40) were surveyed in NYC in 2018 using time-spacing sampling. Participants were asked about past-year ecstasy use, and those...
More than half of prisoners in the United States are estimated to suffer from a substance use disorder. Mindfulness involves attention to the present moment, and nonjudgmental acceptance of sensations, thoughts, and emotional states. Mindfulness-based relapse prevention (MBRP) following substance use disorder treatment has been shown to reduce substance use. We sought to adapt and test MBRP for...
Psychoactive substance use has often been claimed to help generate and facilitate the artistic creative process. This study explored the role of artists' substance use in their creative processes and their efforts to balance between enhancement and relaxation. Semistructured interviews concerning the artistic creative process and the role of psychoactive substance use were recorded with 72...
Drugs of abuse (DOA) are widely used in the United States and are ubiquitous at outdoor music festivals. Attendees at music festivals are at high-risk for novel psychoactive substance (NPS) use, which is becoming more prevalent worldwide. No U.S. studies have employed an qualitative approach to investigate the etiologies of both traditional DOA and NPS use amongst music festival attendees. The...
