Metacognition - the capacity to monitor, interpret, and regulate cognitive processes - is essential for adaptive behavioral regulation. Evidence on how substance use relates to metacognitive functioning remains heterogeneous across substances and study designs. This systematic review synthesized evidence examining the relationship between substance use and metacognition among adults. Following...

Opioid use disorder (OUD) remains a major public health crisis in the United States, with mental health disorders substantially increasing risk severity. Emerging evidence suggests psychedelics may relate to reduced OUD risk. This exploratory study examined associations between lifetime psychedelic use and OUD severity and tested whether these associations varied by mental health impairment....

Cannabis has shown mixed results in its association with alcohol urge, which may be explained by individual differences. One such factor, working memory capacity (WMC) is associated with drug-related cue reactivity and implicated in alcohol use and problems. In the current study, we examined whether WMC moderates the acute effect of cannabis on alcohol urge in a randomized placebo-controlled...

Brief mindfulness meditation induction effectively reduces addictive behaviors in clinical populations, yet their impact on non-addicted individuals remains unclear. This study investigated whether brief mindfulness practice amplifies alcohol enjoyment and consumption in healthy young adults. Across two randomized controlled trials (Study 1:N = 67; Study 2:N = 89), participants with low-risk...

While recent nationally representative studies have evaluated the association between hallucinogen use and mental health events, little is known about these associations among disabled adults. Our primary aim was to use national data from the 2021, 2022, and 2023 National Survey on Drug Use and Health (NSDUH) to determine how past-year use of specific hallucinogens is associated with disabled...

MDMA/Ecstasy motives differ from those of other substances such as alcohol, cannabis, and methamphetamine. Previous literature on alcohol and cannabis use identified social, expansion, enhancement, coping, and conformism as primary motives for use. MDMA/Ecstasy users also report using the drug for increases in self-awareness and energy. The development of an MDMA/Ecstasy use motives assessment...

There is renewed interest in the clinical application of hallucinogenic substances to treat a range of psychiatric conditions. However, there is mixed evidence regarding how use of such substances outside of medical settings relates to psychological distress, depression, and suicidality. We examined data from a US representative sample of noninstitutionalized adults from the 2015-2020 National...

Extending recent studies showing that sensitivity to reward and outcome expectancies are associated with problematic alcohol and cannabis use, we undertook to determine if similar relationships would hold for ecstasy. One hundred and twenty five males and females aged between 18 and 35years were recruited from RMIT University and through snowball sampling. Participants completed a questionnaire...

Salvia, a hallucinogenic plant legally available in most of the United States, has become a widely discussed drug in the media. The extant research on Salvia use relies on non-probability samples and studies of college students. There is a clear need for research that identifies the correlates of Salvia use using data from a large sample that is nationally representative. The current study...

Previous studies have demonstrated that attempts to suppress thoughts about using substances may actually lead to increases in substance use. Vipassana, a mindfulness meditation practice, emphasizes acceptance, rather than suppression, of unwanted thoughts. A study by Bowen and colleagues examining the effects of a Vipassana course on substance use in an incarcerated population showed...

A growing body of research suggests that mindfulness-based therapies may be effective in treating a variety of disorders including stress, chronic pain, depression and anxiety. However, there are few valid and reliable measures of mindfulness. Furthermore, mindfulness is often thought to be related to spirituality, given its roots in Buddhist tradition, but empirical studies on this...

Recreational Ecstasy/MDMA (3,4-methylenedioxymethamphetamine) users often take a variety of psychoactive drugs, but there is little empirical data on how these drug consumption patterns change with greater experience of Ecstasy. The aim of this study was to compare the polydrug usage patterns reported by non-Ecstasy users, novice Ecstasy users, moderate Ecstasy users, and heavy Ecstasy users....
