The Risk of Cardiovascular Events on Cannabis' Highest Day.
Knowledge of the acute cardiovascular effects of cannabis consumption remains largely unknown and is important given the changing landscape of legalization of recreational cannabis use. "4/20" is an annual event where many individuals gather to consume cannabis. An increased risk of adverse health events such as motor vehicle accidents has previously been reported to occur on "4/20." In this study, population-based administrative databases in Ontario, Canada, were used to evaluate the association between "4/20" and cardiovascular events. An increased risk of cardiovascular events on a population level was not observed on "4/20." Additional research into the changes in the prevalence of the use of cannabis with recreational legalization and acute and chronic risk with cannabis use is suggested.
