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...

OBJECTIVES In the modern era of constant digital technological advancements, problematic smartphone use has become a key issue in educational psychology. This phenomenon affects individual psychological well-being and academic or other performance and encompasses interpersonal relationships and societal aspects, divulging the intricate correlation between technology usage and human behavior....
Cannabis potency (concentration of Δ-9-Tetrahydrocannabinol) has been associated with risks of adverse mental health outcomes and addiction but no studies have triangulated evidence from self-report and objective measures of cannabis potency. We hypothesised that users of high potency cannabis would have higher levels of (a) anxiety, (b) depression and (c) psychosis-like symptoms (d) cannabis...

The age cohort referred to as emerging adults (ages 18-29 years old) demonstrates the most hazardous alcohol use in the United States (U.S.) Approximately one-third of emerging adults regularly engage in heavy episodic drinking (4/5 drinks in two hours females/males). Compared to their non-Latine White peers, Latine emerging adults in the U.S. report lower rates of heavy episodic drinking (HED)...
Background and aims: Fear of missing out (FOMO) promotes the desire or urge to stay continuously connected with a social reference group and updated on their activities, which may result in escalating and potentially addictive smartphone and social media use. The present study aimed to determine whether the neurobiological basis of FOMO encompasses core regions of the reward circuitry or social...

Cannabis is associated with a range of therapeutic and non-therapeutic, positive and negative effects. While some benefits and harms may be specific to individual cannabinoid constituents (THC, CBD), individual expectancies may also play a role. Evaluate the extent to which individuals hold expectancies about the effects of CBD, THC, and THC & CBD combined, and whether this differs with prior...

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...

Chronic use of cannabis leads to both motor deficits and the downregulation of CB1 receptors (CB1R) in the cerebellum. In turn, cerebellar damage is often related to impairments in motor learning and control. Further, a recent motor learning task that measures cerebellar-dependent adaptation has been shown to distinguish well between healthy subjects and chronic cannabis users. Thus, the...

AIM To test the age, cohort, and period effect on past-year use trends in psychedelic drugs and ecstasy. METHOD Data were from a repeated cross-sectional nationally representative household survey in Australia conducted every three years between 2001 and 2019. An age-period-cohort model was used to test the effect of age, birth cohort, and period on past year psychedelic and ecstasy use....
BACKGROUND: An attentional bias towards substance-related stimuli has been demonstrated with alcohol drinkers and many other types of substance user. There is evidence to suggest that the strength of an attentional bias may vary as a result of context (or use intention), especially within Ecstasy/MDMA users. OBJECTIVE: Our aim was to empirically investigate attentional biases by observing the...
Recent data suggest that both nonmedical prescription drug and MDMA (ecstasy/molly) use have risen among African Americans. However, studies investigating these two forms of drug use among African Americans are rare. As a result, very little is known about African-American MDMA users and their nonmedical use of prescription medications. The primary goal of this study, therefore, was to describe...

Introduction: Mindfulness-based treatments have received increasing interest and empirical support in the clinical psychology literature. There are, however, no studies to date that have systematically examined treatment enactment, which is the amount and type of home practice participants incorporate into their daily lives. Because treatment enactment has been cited as a key aspect of...
Objective With the recent debates over marijuana legalization and increases in use, it is critical to examine its role in cognition. While many studies generally support the adverse acute effects of cannabis on neurocognition, the non-acute effects remain less clear. The current study used a cross-sectional design to examine relationships between recent and past cannabis use on neurocognitive...
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...
Cognitive deficits that persist up to a month have been detected among adult marijuana users, but decrements and their pattern of recovery are less known in adolescent users. Previously, we reported cognitive deficits among adolescent marijuana users after one month of abstinence (Medina, Hanson, Schweinsburg, Cohen-Zion, Nagel, & Tapert, 2007). In this longitudinal study, we characterized...
