Using ecological momentary assessment to quantify Δ-9-tetrahydrocannabinol and cannabidiol use across different forms of cannabis: Feasibility in a sample of Canadian young adults reporting frequent cannabis use.

Aims: To establish the feasibility of using ecological momentary assessment (EMA) to estimate total quantities of Δ-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) used across different forms of cannabis, and to assess the predictive validity of THC estimates for predicting acute cannabis-related consequences.

Design: 14-day EMA using a smartphone application to assess cannabis use in real time.

Setting: Canada.

Descriptive norms for simultaneous cannabis and alcohol use predict simultaneous use patterns assessed via daily surveys.

Objective: Simultaneous cannabis and alcohol use is common, but few studies have examined normative perceptions of simultaneous use. This study examined unique associations of baseline descriptive norms for simultaneous use (i.e.

Expressive Writing About One's Trauma Increases Accessibility of Cannabis Information in Memory Among Trauma-Exposed Individuals.

Objective: Trauma survivors are more likely than others to use cannabis, and post-traumatic stress disorder (PTSD) commonly co-occurs with cannabis use disorder (CUD). Automatic memory associations between trauma reminders and cannabis use have been suggested as contributing mechanisms. These associations can be studied experimentally by manipulating trauma cue exposure in a cue-reactivity paradigm (CRP) and examining effects on the accessibility of cannabis information in memory in trauma survivors with and without PTSD.

Correlates of Using Medically-Authorized Cannabis in a Large Cohort of People Living with HIV Who Use Cannabis.

Many people living with HIV (PLWH) use cannabis to manage symptoms, but a large proportion do so without medical cannabis authorization and use cannabis obtained outside the medical stream. In jurisdictions where non-medical cannabis use is legal, PLWH who hold medical cannabis authorization may represent a unique subgroup; yet, research on the correlates of using medical cannabis (authorized by a healthcare provider) in the context of non-medical cannabis legalization is lacking. Thus, this study examined the cannabis- and health-related correlates of medical cannabis use among PLWH in Ontario, Canada, where non-medical cannabis is legal.

Proximal antecedents and acute outcomes of simultaneous alcohol and cannabis use: Systematic review of daily- and event-level studies.

Many studies have revealed that individuals who engage in simultaneous use of alcohol and cannabis report elevated substance-related consequences relative to those who use only alcohol or cannabis; however, evidence from emerging studies examining within-person differences across simultaneous use and single substance use occasions is less consistent. This systematic review aimed to synthesize findings from existing day- and event-level studies of within-person differences in the proximal antecedents and acute outcomes associated with simultaneous use versus single substance use episodes.
