Simultaneous use of cannabis with other drugs
BACKGROUND: Rates of cannabis use are rising, with potential public health implications. However, many people who use cannabis use it simultaneously with other psychoactive drugs such that their intoxicating effects overlap. Thus, it is important to understand cannabis use in the context of simultaneous use with other substances, especially in jurisdictions with legal access to cannabis. We used latent class analysis (LCA) to identify patterns of…
Cognitive Dysfunction in the Addictions (CDiA)
Substance use disorders (SUDs), including Alcohol Use Disorder, are pressing global public health problems. Executive functions (EFs) are prominently featured in mechanistic models of addiction. However, significant gaps remain in our understanding of EFs in SUDs, including the dimensional relationships of EFs to underlying neural circuits, molecular biomarkers, disorder heterogeneity, and functional ability. Transforming health outcomes for peop…
Characterizing Heterogeneity in Substance Use in a Large Sample of Canadian Adolescents
Indirect Associations Between PTSD Symptoms and Cannabis Problems in Young Adults
Background: Cannabis use in young adulthood has been associated with exposure to traumatic events and posttraumatic stress disorder (PTSD). Coping motives for cannabis use represent one mechanism linking PTSD with cannabis problems, yet some individuals with PTSD consider their cannabis use to be medicinal in nature. While a medicinal orientation to cannabis overlaps conceptually with coping motives, it could be associated with unique cannabis ou…
Examining the psychometric properties of the electronic gaming motives questionnaire in a sample of Canadian adults
Longitudinal co-trajectories of depression and alcohol problems in adults during the Covid-19 pandemic
Different classes of crystal methamphetamine use are associated with psychological and sexually transmitted infection outcomes among gay, bisexual, and other men who have sex with men
Internalizing personality traits and coping motivations for gaming during the Covid-19 pandemic
Anxiety sensitivity and hopelessness are two traits that have been previously linked to increased gaming problems. Research in the early stages of the COVID-19 pandemic showed that emotionally vulnerable individuals were turning to video games as a means of coping with their distress. However, more research is needed on the long-term and enduring pathways from internalizing traits to time spent gaming during COVID-19, after the lockdowns and prev…
Examining the relationship between acceptance of different models of addiction and individual stigma among outpatients with alcohol and opioid use disorders
Demographic, Mental Health, and Substance Use Correlates of Self-Described Medicinal Use, Recreational Use, and Non-Use of Hallucinogenic Drugs
Examining the relationship between public stigma, models of addiction, and addictive disorders
The current study provides further support that addictive disorders are more stigmatized than other health disorders and suggests that beliefs in specific MOAs are differentially associated with stigma. Interventions addressing addiction stigma may consider incorporating information emphasizing MOAs that are less stigmatizing
Correlates of Using Medically-Authorized Cannabis in a Large Cohort of People Living with HIV Who Use Cannabis
Efficacy of a novel online integrated treatment for problem gambling and tobacco smoking
Gaming as a coping strategy during the Covid-19 pandemic
Early in the COVID-19 pandemic, social interactions were constrained by physical distancing guidelines. Consequently, some individuals may have turned to video games to cope with isolation and negative emotions. Previous studies have shown that people who struggle with anxiety and depression are at particular risk for developing problem gaming behaviours. However, there is a paucity of longitudinal research testing pathways from negative emotiona…
Characterizing heterogeneity among people who use cannabis for medicinal reasons
Measuring Impaired Control over Cannabis Use
Background: Impaired control is a central concept in addiction. Impaired control over alcohol has been associated with heavy drinking and alcohol-related problems in young adults, but there is less research on impaired control over cannabis. Currently, there is no validated self-report instrument that comprehensively assesses impaired control over cannabis use. This study examined the factor structure, reliability, and validity of a new measure, …

Shame’s Associations with Depression and Problem Drinking
INTRODUCTION: Depression and problem drinking are comorbid in emerging adulthood, yet the processes that link them are not well understood. Research has argued that shame has a unique influence on the experience of problematic drinking, but this has rarely been assessed at the state level. Using ecological momentary assessments (EMAs), we assessed whether shame, and not guilt, mediated the association between baseline depression and alcohol use a…
Daily associations between cannabis use and alcohol use in young adults
Although impulsivity has been implicated in cannabis and alcohol use, its role in alcohol and cannabis co-use behavior requires further study. We examined the moderating role of self-report and behavioral measures of impulsivity in the daily-level relationships between cannabis use and both (a) likelihood of same-day alcohol use and (b) the number of drinks consumed on the same day. Young adults (n = 153) completed a 90-day Timeline Follow Back a…
Drinking to Cope During Covid‐19 Pandemic
BACKGROUND: The COVID-19 pandemic has resulted in massive disruptions to society, to the economy, and to daily life. Some people may turn to alcohol to cope with stress during the pandemic, which may put them at risk for heavy drinking and alcohol-related harms. Research is needed to identify factors that are relevant for coping-motivated drinking during these extraordinary circumstances to inform interventions. This study provides an empirical e…
Can Brief Email Guidance Enhance the Effects of an Internet Intervention for People with Problematic Alcohol Use? A Randomized Controlled Trial
BACKGROUND: email in an internet intervention for problem drinkers
Depression, Environmental Reward, Coping Motives and Alcohol Consumption During the Covid-19 Pandemic
Background: Increases in the incidence of psychological distress and alcohol use during the COVID-19 pandemic have been predicted. Behavioral theories of depression and alcohol self-medication theories suggest that greater social/environmental constraints and increased psychological distress during COVID-19 could result in increases in depression and drinking to cope with negative affect. The current study had two goals: (1) to examine self-repor…
An evaluation of alcohol sensitivity in the context of the acquired preparedness model
Future research is necessary to reconcile these results with laboratory findings suggesting that impulsive traits are frequently associated with sensitivity to alcohol's acute effects
