Summary: The legalizations of medical and recreational cannabis have sparked interest in studying its health impacts, but documentation of cannabis use during clinical visits is still not common. This lack of information hinders research on cannabis's effects on health outcomes. We developed a natural language processing pipeline to evaluate trends in cannabis documentation and found that its rate is very low but growing (<2%) in electronic health records, with significant disparities in both documentation and positive use based on demographics and socioeconomic factors.

Supporters of medical cannabis are more likely to have chronic pain, while supporters of recreational cannabis are more likely to suffer from psychological distress. Recent cannabis users are significantly more likely to support the legalization of both medical and recreational cannabis.

Summary: This study examines the impacts of cannabis legalization on youth cannabis use in Canada. Findings show that the initiation rate among youths increased by 2.7 percentage points after legalization, but there was no significant increase in overall cannabis use prevalence. The average age of first cannabis use was also delayed by 4 months. The legalization led to heightened perception of cannabis harm and easier access to cannabis among youth.

Summary: This study examined the patterns of concurrent use and co-administration of tobacco and cannabis among young adult college students in Texas from 2016 to 2019. Four latent classes were identified, and most students remained in the same class over the course of the study. The findings suggest the need for prevention and cessation programs that address the constellation of behaviors related to cannabis and tobacco co-use.
