A recent poll commissioned by the Canadian Automobile Association about cannabis consumption and road safety suggests that one in two cannabis users have driven a vehicle while intoxicated.
The survey of 1,000 Ontarian drivers over the age of 19 also indicated that 69 per cent of cannabis-impaired drivers were male and drivers between the ages of 25 and 34 were most likely to drive under the influence.
CAA South Central Ontario has extrapolated polling results and claims that 1.9 million Ontario drivers have driven under the influence.
From a public health perspective, the impact of cannabis on the operation of motor vehicles is a concerning consequence of cannabis legalization.
Studies indicate THC impacts reaction time, visual function and concentration. It also compromises your ability to handle unexpected events and doubles your risk of a collision.
There are currently no standardized measurements of THC levels available in cannabis strains and products. There is also an absence of peer-reviewed evidence correlating the impact of THC levels with impairment.
These issues lead CMHA Ontario to recommend to government a zero-tolerance policy for cannabis consumption in any motorized vehicle.
In its submission to the Ministry of Attorney General in August 2017, CMHA Ontario also recommends the government invest and work to develop a comprehensive public education strategy to send a clear message to Ontarians that cannabis use causes impairment, and the best way to avoid driving impaired is not to consume.
