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.
Future randomized controlled studies are needed to determine dosing, efficacy, and safety of medical marijuana for the treatment of various forms of itch....

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).
