How long should I wait to drive after consuming cannabis edibles?

According to CAA-funded research, young Canadians who inhale cannabis are at a greater risk of a vehicle crash even five hours after consumption. The effects of edible cannabis can take longer to appear, and the impairing effects can last longer too. While research varies, edibles may remain in your system for up to 12 hours. Edibles may cause a different or delayed type of high compared to smoking and as such it is important to know your plans before eating anything. Schedule a rideshare, have a designated driver or spend the evening at home – just don’t get behind the wheel. (Centre for Addiction and Mental Health).
