Newest firstPain is prevalent among people with HIV (PWH), and many PWH who experience pain also use substances (illicit drug and/or unhealthy alcohol use). While cocaine use and cocaine and alcohol co-use are prevalent in this population, their effects on pain in PWH are unknown. This study aims to investigate the association of cocaine use and co-use of cocaine and alcohol with pain interference among PWH. We completed a se…
Background Educational attainment (EA), which comprises cognitive (CogEA) and noncognitive (NonCogEA) components, is positively genetically correlated with alcohol and cannabis use but negatively correlated with alcohol and cannabis use disorders (AUD and CUD). These paradoxical associations suggest that shared genetic influences with EA may differ by level of substance involvement. Methods To test this, we examin…
Comorbid substance use disorders (SUDs) are common but difficult to study due to the complex, interacting and overlapping mechanisms through which they affect brain networks. Many datasets collected to investigate a specific SUD include participants with comorbid SUDs. Although most studies treat comorbid SUDs as covariates of no interest, these covariates also contain untapped information. This is particularly re…
Neuropsychiatric disorders represent a significant global health burden. Despite decades of research, current treatments typically provide only symptomatic relief, rather than addressing the underlying mechanisms of these conditions. Historically, research focused on the dopaminergic and serotonergic systems, which are deeply involved in the pathophysiology of many mental health disorders, including depression, sc…
Rationale Negative affect is a key factor in Alcohol Use Disorder (AUD) associated with craving and relapse risk that is insufficiently treated by approved medications. Cannabidiol (CBD) has shown promising effects on negative affect, indicating its potential for addressing the neurocircuitry underlying negative affect in AUD. Objectives This study investigates CBD's effects on neural response to negative emotiona…
Alcohol use disorder (AUD) remains a pervasive public health issue with limited effective treatments. Cannabidiol (CBD), a non-psychotropic constituent of cannabis, shows promise in modulating addictive behaviors. This study investigated the effects of chronic CBD administration on alcohol dependence, withdrawal symptoms, and neurodegeneration using two complementary rodent models: chronic intermittent ethanol (CI…
BACKGROUND: Early initiation of alcohol, nicotine, cannabis, and other substances is a robust predictor of later substance use disorders and related psychopathology. We integrate time-varying environmental factors with polygenic risk scores (PRS) in a longitudinal framework to identify risk factors influencing substance initiation in adolescents. METHODS: We analyzed data from the Adolescent Brain Cognitive Develo…
Background: Attention-Deficit/Hyperactivity Disorder (ADHD) in adulthood is frequently associated with complex psychiatric comorbidity, including high rates of Substance Use Disorders (SUDs), which may influence treatment outcomes. Although pharmacological treatments are effective for core ADHD symptoms, real-world response remains heterogeneous, and the contribution of specific substance-related and neurodevelopm…
Background Romantic relationships are important contexts for substance use and emotional well-being. We tested the hypotheses that (i) genetic predispositions for alcohol consumption would be positively associated with partner substance use, (ii) partner substance use would moderate genetic influences on one's own alcohol outcomes, and (iii) partner discordance in substance use would be associated with lower emoti…
Substance use disorders (SUDs) remain a major public health concern and contribute substantially to compromised quality of life, mortality, and healthcare burden. In the United States alone, millions of individuals are affected by alcohol use disorder (AUD), tobacco use disorder (TUD), and opioid use disorder (OUD), with many cases complicated by co-existing anxiety and stress-related disorders. Piper methysticum…
Aims To describe differences in the expression of genes encoding cannabinoid receptors (CNR1, CNR2), the associated receptor GRP55 and the enzymes fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MGLL) between individuals with alcohol use disorder (AUD) and controls in key mesocorticolimbic brain regions. Design Case-control, observational postmortem study comparing gene expression in brain tissue fr…
Background Conventional psychological and pharmacological substance abuse treatments are limited to moderate effect sizes and fail to magnify outcomes when combined. Analog psychedelic agents N, N-dimethyltryptamine (DMT) and 5-methoxy-N, N-dimethyltryptamine (5-MeO-DMT) show therapeutic potential for treatment-resistant psychiatric disorders including substance addictions. Methods This systematic review and meta-…
Background and hypothesis Evidence suggests a complex interplay among childhood trauma (CT), substance use, and psychopathology in psychosis, yet the precise nature of these relationships remains unclear. Network analysis offers distinct advantages for examining these factors simultaneously, as it can capture multidirectional associations across multiple trauma subtypes, substances, and symptoms that conventional…
Background Two-thirds of adults in the United States (U.S.) find recreational and medical cannabis use acceptable. Evidence shows that cannabis use is an effective treatment for pain, and as a harm reducing therapeutic for Substance Use Disorder (SUD). In contrast to most SUD treatment models, some models allow illegal substance use as a harm reduction strategy, which is the case for the SUD treatment program exam…
Addiction poses a major global public health challenge. It is characterized by high prevalence, chronic relapse and limited efficacy of available pharmacotherapies across different substance use disorders. Increasing evidence demonstrates that incretin-based therapies directly modulate metabolic signaling pathways that intercross with central reward and motivational circuits, including hypothalamic-mesolimbic netw…
Background Substance use disorders (SUDs) remain a major source of preventable morbidity and mortality in the United States. This study described trends in the burden of SUDs from 1990 to 2019 by substance, sex, and age, and examined whether state-level policy environments and behavioral health budgets differed across states with the highest and lowest SUD-related disability-adjusted life years (DALYs). Methods We…
Background The COVID-19 pandemic disrupted face-to-face alcohol and other drug (AOD) treatment services and prompted greater use of telehealth. This study measured the impact of COVID-19 on outpatient treatment episodes before, during, and after stay-at-home orders were introduced. Methods This observational study used routinely collected data from community-based non-government AOD services in New South Wales (NS…
Background Substance use disorders (SUDs) are widely prevalent and associated with high morbidity and mortality. Current treatments have limited efficacy and there are no United States Food and Drug Administration (FDA)-approved treatments for several SUDs (such as methamphetamine, cocaine, and cannabis use disorders). Emerging evidence suggests glucagon-like peptide 1 receptor agonists (GLP-1RAs) may improve outc…
Background:Adolescents with co-occurring alcohol use and mental health disorders have better treatment outcomes when caregivers are involved in their treatment. Currently, little is known about why caregiver involvement improves outcomes.Objectives:To facilitate caregiver-involved treatment process research, this study preliminarily examined within- and between-person variability in ecological momentary assessment…
Alcohol Use Disorder (AUD) is a prevalent and debilitating neuropsychiatric condition characterized by compulsive alcohol consumption, impaired control, and negative emotional states, affecting about 28 million adults in the United States. Despite its significant public health burden, there are few objective biomarkers and no reliable neurophysiological tools to assist in its clinical diagnosis. In this study, we…
