Congratulations to Dr. Jeff Brubacher and co-investigators Mark Asbridge, Rollin Brant, Herbert Chan, Shannon Erdelyi, and Scott MacDonald on their recently awarded CIHR grant ($845,325 over five years) for their study “Evaluation of the effect of cannabis legalization on road safety”. This project will continue Dr. Brubacher’s “Cannabis and Motor Vehicle Crash Risk” study in order to evaluate the effect of cannabis legalization on the prevalence of injured drivers who test positive for THC, the active ingredient in cannabis. The study will also refine estimates of motor vehicle crash risk at various THC levels.
