Psychoactive substances are compounds that can influence perception, consciousness, cognition, and emotions. The psychoactive substances caffeine, nicotine, cannabis, and psilocybin all originate from natural sources and can be used without complex processing or synthesis. Their natural availability has contributed to a long-standing history of human use and cultural significance. Caffeine and...
A growing body of evidence points to a role for mindfulness in the development or maintenance of co-occurring posttraumatic stress disorder (PTSD) and substance use disorder (SUD). However, the mechanisms of this relationship remain unclear in the veteran population. This study seeks to understand how PTSD and facets of mindfulness are associated with factors of SUD in veterans enrolled in a VA...
Internet gaming disorder (IGD) is a pervasive global mental health issue, and finding effective treatments for the disorder has been challenging. Mindfulness meditation (MM), recognized for its holistic approach that involves integrating mental and physical facets, holds promise for addressing the multifaceted nature of addiction. Nevertheless, the effect of MM on IGD and its associated neural...
There are few effective pharmacotherapies for treating eating disorders (EDs). High rates of substance use among individuals with EDs suggest potential self-medication of symptoms. To explore the experiences of individuals with EDs regarding use of prescribed and nonprescribed drugs. This survey study assessed responses to the Medications and Other Drugs for Eating Disorders (MED-FED) survey,...
School-based mindfulness programs (SBMPs) have shown a range of academic, emotional, and behavioral outcomes. However, heterogeneity in curricular content obscures accurate interpretation of results. To unpack the "black box" of SBMPs and better contextualize intervention outcomes, this investigation examined the practices, skills, and knowledge conveyed in twelve curricula. Required curricular...
The positive effects of mindfulness have been studied extensively, but research identifying how mindfulness works is lacking. This study aimed to investigate two possible working mechanisms of mindfulness. First, we explored whether mindfulness works by buffering the negative effects of work stress. Second, we tested whether mindfulness improves work outcomes through the enhancement of...
Ketamine is a rapid-acting antidepressant with sexually dimorphic effects. Female animals exhibit a higher sensitivity to its antidepressant properties, which has been associated with their ovarian hormone levels. One factor contributing to this sex difference is the faster rate of ketamine metabolism observed in females, potentially regulated by estrogen receptor alpha (ERα) through modulation...
Synthetic cannabinoids (SCs) are potent agonists of CB1 and CB2 receptors, with affinities approximately 100 times greater than that of natural cannabis. This increased potency is associated with severe clinical outcomes, including psychosis, dependence, and various autonomic disturbances, such as seizures and rhabdomyolysis. The objective of this study was to synthesize the existing literature...
The primary objective of this review is to highlight the increasing relevance of experimental neuroscience in advancing the mechanistic understanding and translational potential of classic psychedelics and other psychoactive substances of interest. First, we review clinical evidence for the therapeutic potential of psychedelics in the context of depression, anxiety, and addiction. Second,we...
Psychedelics, derived from the Greek words "psyche" (soul) and "deloun" (revealing), are substances historically and currently considered "soul-revealing". Also termed hallucinogens due to their impact on sensory perception, they are further categorized into hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and mescaline; entactogens or empathogens, such as...
