Study: No spike in traffic-related injuries after Canada legalized recreational cannabis


Neither Ontario nor Alberta — far and away, the leaders for the number of cannabis stores in the country — have witnessed a significant rise in emergency visits from traffic-related injuries since weed got the green light three years ago. “Implementation of the Cannabis Act was not associated with evidence of significant post-legalization changes in traffic-injury emergency department (ED) visits in Ontario or Alberta among all drivers or youth drivers, in particular,” notes the new Canadian study in Drug and Alcohol Dependence. Published last week, researchers sought to get firm numbers afters some have expressed concerns about how recreational cannabis legalization could influence road-related injuries, particularly with respect to youth drivers. To get to firm numbers, investigators considered weekly drivers’ traffic injuries at all EDs in Ontario and Alberta from the start of April 2015 (three years before legalization) through the end of 2019. […] “There was no evidence of significant changes associated with cannabis legalization on post-legalization weekly counts of drivers’ traffic-injury ED visits,” researchers write.
