Newest firstBACKGROUND: Cannabis, the most consumed illicit drug globally, has been legal for non-medical use in Canada since 2018. Problematic internet use is considered a behavioral addiction involving excessive online activities (e.g., social media, video watching), which can cause social isolation, family issues, psychological distress, and even suicide ideation. Studies mainly conducted with adolescents indicate a link b…
Open article record in new tab ↗Background and Objectives: One of the strongest early factors influencing later psychoactive substance use is adverse childhood experiences (ACEs). Studies investigate a variety of adverse experiences in relation to substance use, yet not all adverse childhood experiences are equal in intensity and harm. Our study aimed to address this gap by examining in detail the associations between individual ACEs, broader AC…
Open article record in new tab ↗ObjectiveIn this study, we evaluated the concordance between urine drug screening (UDS) and self-reported use in a pragmatic randomized clinical trial.MethodsOur data was drawn from OPTIMA, a 24-week pragmatic multicentric open-label randomized-controlled trial comparing flexible take-home dosing of buprenorphine/naloxone to the methadone standard model of care for treating prescription-type opioid use disorder. A…
Purpose Substance use and substance use disorders (SUD) disproportionately affect people with disabilities (PWD), yet PWD remain under-represented in addiction treatment literature. While recent work has begun to address SUD prevalence and recovery service gaps, little is known about how disability status shapes substance use outcomes. The present study is the first to our knowledge to investigate how recovery, me…
Adolescents experience extensive neurocognitive development, with cannabis use potentially impacting developmental trajectories. Here, we comprehensively assess the influence of adolescent cannabis use onset on neurocognitive trajectories and consider how recent delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) may influence neurocognition. We use the large, diverse longitudinal Adolescent Brain Cognitive D…
Objective To assess the prevalence of CBD use among US adults, identify the health conditions for which CBD is used, and examine whether CBD is used as a substitute or adjunct to conventional treatments. Design setting and participants This cross-sectional survey used Ipsos KnowledgePanel®, a US probability-based online panel covering approximately 97% of US adults and including households without internet access…
Aims To estimate the prevalence of prenatal cannabis use in Michigan, USA, using self-reports and urine toxicology and to examine factors associated with use. Design Observational study using data from the Michigan Archive for Research on Child Health (MARCH) cohort, part of the National Institutes of Health's Environmental influences on Child Health Outcomes (ECHO) program. It is a prospective statewide pregnancy…
This study uses keyword filtering, a transformer-based algorithm, and inductive content coding to identify and characterize cannabis adverse experiences as discussed on the social media platform Reddit and reports a total of 1177 self-reported adverse experiences requiring medical attention.
Open article record in new tab ↗Prospective memory (PM) deficits are common among people with HIV (PWH) and are linked to poor clinical outcomes. Risk factors for PM deficits in PWH are poorly understood. While cannabis use is associated with worse PM in people without HIV, it is unclear whether this association generalizes to PWH. Three hundred and seven PWH (79% with regular cannabis use) completed the Memory for Intentions Test (MIST). Associ…
Open article record in new tab ↗Background With the rising prevalence of daily cannabis use in the U.S., more individuals may seek treatment for adverse outcomes (e.g., cannabis use disorder) arising from frequent cannabis use. Adaptive interventions leverage self-reported motives for cannabis use to develop personalized support. Research has demonstrated that these motives can be collected on a yearly, monthly, or daily basis, and strongly pred…
Open article record in new tab ↗Background While cannabis use is prevalent among people with HIV (PWH), factors associated with higher-risk use require further study. We examined factors (mental health, sociodemographics, substance use, HIV clinical markers) associated with risk for cannabis use disorder (CUD) among PWH who used cannabis. Methods Participants included adult (≥ 18 years old) PWH from 3 HIV primary care clinics in Kaiser Permanent…
Open article record in new tab ↗Following bariatric surgery (BS) patients have an increased risk of alcohol misuse. Purpose This 1-year cross-sectional study in potential BS candidates had several objectives: (a) assess the prevalence of risky drinking, alcohol use disorder (AUD), and other substance use/disorder; (b) compare the prevalence of these behaviors to that of the general Spanish population; (c) determine the proportion of patients wit…
Aims To identify variation in identification of medical consumers using alternative self-reported measures and assess whether differences in these rates exist across jurisdictions with different medical policy approaches using evidence from an international study on cannabis use. Design Secondary analysis of wave 4 (2021) of the International Cannabis Policy Study (ICPS) cross-sectional survey. Setting United Stat…
Background Chronic pain is among the leading causes of disability worldwide, of which only a small percentage of patients receive adequate treatment for. Non-prescribed opioid analgesics are commonly sought out in effort to alleviate unrelieved pain. This study assesses the prevalence and correlates of chronic pain among primary fentanyl users. Methods A cross-sectional and structured survey was conducted with 200…
Background While prior studies have shown LGB individuals have elevated risk of poor mental health, poor physical health, and substance use, existing study designs may be improved by using representative samples, wider ranges of health outcomes, heterosexual comparison groups, and disaggregated data. The goal of this study is to provide estimates of multiple health disparities across sexual orientations in Canada…
Open article record in new tab ↗Introduction Cancer patients are increasingly turning to cannabis products to modulate physical and psychological symptoms despite limited evidence supporting their efficacy. We aimed to explore cancer patients' self-reported anxiety and depression symptoms in response to cannabis use. Methods This longitudinal study examined how patient-reported anxiety and depression symptoms varied according to the dose, ratio…
Open article record in new tab ↗Accurate assessment of substance use is essential in public health, clinical, and research settings. While self-reports are widely used, they are prone to biases such as social desirability and recall errors. Objective biological measures, such as hair toxicology, offer a longer detection window and may improve data validity. This study examined the concordance between self-reported substance use and hair toxicolo…
Background Cannabis use during pregnancy is increasingly common and is associated with adverse health outcomes for pregnant individuals and their offspring. Identifying preconception factors that are associated with prenatal cannabis use is critical to inform early prevention and intervention. This study tested whether frequency of preconception cannabis use was associated with cannabis use during early pregnancy…
Background Cancer-related cognitive impairment (CRCI) is reported by 45% of patients with cancer. Significant gaps in knowledge remain regarding the mechanisms that underlie CRCI. Objectives Using a data-driven approach, the study purpose was to evaluate for perturbed pathways associated with membership in the High versus the Low CRCI profiles. Methods Patients completed the Attentional Function Index six times ov…
