(NP Montreal, May 18) An Australian government study of impairment of pilots concluded that "residual effects of cannabis can persist for up to 24 hours. These effects include persisting difficulty with psychomotor tasks and interference with cognitive function." The Trudeau government seems intent on increasing access to marijuana, but a government that is pledged to implement evidence-based policy should recognize that allowing for more people to drive impaired without police being able to easily measure their degree of impairment runs contrary to public safety. Sorry for the buzzkill, but are you really okay with the driver you encounter at the next intersection being not sober enough to pilot a plane but intoxicated enough to risk the lives of your family and fellow motorists?
