Canada sees steady trends in marijuana positive tests among truck drivers since legalization
Despite the legalization of marijuana in Canada and several U.S. states, the rate of positive drug tests among Canadian cross-border truck drivers has remained consistent. This is according to Jonathan Davids, corporate medical director of DriverCheck Inc., Canada’s provider of workplace medical testing and assessments. He says the stability highlights the critical role of testing, education, and supervisor training in maintaining road safety.
