About The Study: This study found large increases in cannabis involvement in emergency department visits for traffic injury over time in Ontario, Canada, which may have accelerated following nonmedical cannabis commercialization. Although the frequency of visits was rare, they may reflect broader changes in cannabis-impaired driving. Greater prevention efforts, including targeted education and policy measures, in regions with legal cannabis are indicated.
