Newest firstBackground 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…
Open article record in new tab ↗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…
Open article record in new tab ↗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…
Open article record in new tab ↗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…
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…
Open article record in new tab ↗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 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: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…
Introduction Cannabidiol (CBD) has recently gained attention for its potential therapeutic effects in substance use disorders, including Alcohol Use Disorder (AUD). This study examined the potential therapeutic effects of commercially available products containing CBD with and without a small amount of tetrahydrocannabinol (THC) on alcohol use and craving among individuals with moderate to severe AUD. Methods In t…
Open article record in new tab ↗The cannabinoid receptor 1 (CB1R) in the hippocampus has been involved in impulsivity and alcohol consumption in adolescent rats. However, the role of CB1R in the cerebellum, despite that structure's exceptionally high CB1R density, remains unexplored. We therefore tested the hypothesis that cerebellar CB1R contributes to regulating impulsive behaviour, alcohol consumption and seeking. Male Wistar rats, adolescent…
Open article record in new tab ↗Aims To measure the associations between racial discrimination and distinct alcohol and other drug use outcomes in minoritised racial/ethnic groups and to explore the moderating roles of demographic and methodological characteristics. Methods Quantitative studies including racial discrimination as an exposure (both binary and continuous), an alcohol and/or other drug use outcome and a minoritised racial/ethnic sam…
Introduction Borderline personality disorder (BPD) patients exhibit high rates of co-occurring mental disorders. Though literature reports varying prevalence of substance use disorders (SUD) in BPD, they are frequent with prevalence rates of approximately 45%. This study examines the 12-month prevalence of SUDs in a German sample of BPD patients by semi-structured interviews and compared to medical records. Method…
Alcohol use disorder (AUD) is a prevalent psychiatric condition characterised by problematic alcohol consumption and craving, necessitating the exploration of novel therapeutic interventions. Cannabidiol (CBD), a non-psychoactive component of cannabis, has shown potential in modulating neural processes associated with substance use disorders including AUD. This study aimed to investigate the effect of CBD on alcoh…
With increasing substance misuse among older adults, we examined the question of whether older adults may be less likely to endorse certain DSM-5 criteria for alcohol and cannabis use disorders (AUD and CUD). We used the 2021-2023 National Surveys on Drug Use and Health (N = 17,494 for AUD and N = 12,264 for CUD) and descriptive statistics to compare the 65+ and under 65 age groups in their endorsements of 11 DSM-…
Open article record in new tab ↗Background This study examines the prospective associations of alcohol and drug misuse with suicidal behaviors among service members who have left active duty. We also evaluate potential moderating effects of other risk factors and whether substance misuse signals increased risk of transitioning from thinking about to attempting suicide. Method US Army veterans and deactivated reservists (N = 6,811) completed surv…
Dopamine D2 receptor (D2R)-mediated signalling is involved in reward, motivation and alcohol use disorder. Perturbation of the D2R system may influence an individual's response to alcohol. Alternative splicing of the D2R gene generates two isoforms: D2 long form (D2L) and D2 short form (D2S). It is unclear whether differences in the expression of D2L and D2S influence alcohol's effects. Here we examined if altered…
Objective To identify factors associated with incident alcohol consumption, hazardous drinking, alcohol-related problems, and substance use up to 8 years following metabolic and bariatric surgery (MBS) during adolescence. Background In this cohort, nearly half of those who underwent MBS as adolescents screened positive for alcohol use disorder, symptoms of alcohol-related harm, or alcohol-related problems within 8…
Open article record in new tab ↗The underlying neurobiological mechanisms of cannabidiol's (CBD) management of alcohol use disorder (AUD) remains elusive.Aim We conducted a systematic review of neuroimaging literature investigating the effects of CBD on the brain in healthy participants. We then theorise the potential neurobiological mechanisms by which CBD may ameliorate various symptoms of AUD.Methods This review was conducted according to the…
Open article record in new tab ↗Background & objectives Tobacco (30%), alcohol (21.4%) and cannabis (3%) are the three most commonly abused substances in India. Tobacco and alcohol abuse have higher prevalence rates among different occupational groups as compared to that in general population in the country. Both tobacco and alcohol lead to significant occupational harm in terms of absenteeism, injuries, sickness and lost productivity. This stud…
