MedicalResearch.com Interview with: Carmen Lim BSc(Hons), MSc, CStat PhD Candidate National Centre for Youth Substance Use Research Faculty of Health and Behavioural Sciences The University of Queensland Brisbane Australia MedicalResearch.com: What is the background for this study? What are the main findings? Response: This review has systematically summarized the trends and products used for cannabis vaping using 17 studies published globally between Jan 1, 2003 and August 19, 2020. The pooled prevalence has increased for lifetime use (6.1% in 2013 to 13.6% in 2020), past-year use (7.2% in 2017 to 13.2% in 2020) and past-month use (1.6% in 2013 to 8.4% in 2020). Adolescents' preference for cannabis products may be shifting from less potent products (e.g., herbal cannabis) to highly potent vape oil and concentrates.

Response: In a previous study that was published in JAMA Pediatrics, we used Youth Risk Behavior Survey (YRBS) data and found that the adoption of recreational marijuana laws (RMLs) was associated with an 8% decrease in the odds of marijuana use among high school students.  This earlier study, however, had pre-legalization and post-legalization data from only 7 states and pre- and post-recreational sales data from only 3 states, calling into question the generalizability of our findings.

MedicalResearch.com Interview with: [caption id="attachment_57068" align="alignleft" width="200"]Sarah Windle Sarah Windle[/caption] Sarah Windle, MPH PhD Student in Epidemiology Department of Epidemiology, Biostatistics, and Occupational Health McGill University (Montréal, Québec, Canada) MedicalResearch.com: What is the background for this study? Response: Concerns have been raised about the potential for increases in impaired driving following the legalization of recreational cannabis use in Canada in October 2018. Data from Statistics Canada suggest that cannabis use in the previous three months increased among adults (15 and older) from 14% before legalization in 2018 to 17% in 2019. Among those users with a driver’s license, 13% reported driving within two hours of cannabis use. While this proportion remained the same before and after legalization, this indicates that the absolute number of individuals who reported driving within two hours of use has increased following legalization (due to an increase in the number of users).
