Drug impaired driving rates have doubled since Parliament legalized marijuana, says a Department of Justice report. Legalization was accompanied by Bill C-46 An Act To Amend The Criminal Code that allowed random roadside drug testing.

“The rate of drug-impaired driving offences increased 105 percent from 2017 to 2020, from nine to 19 offences per 100,000 population respectively,” said the report Cannabis Crime Statistics. “Due to the new legislation, police have additional means available to detect drug-impaired driving which may in part explain this increase.”

“The rate of drug-impaired driving offences increased in all but two jurisdictions,” it said. The exceptions were Nunavut and the Northwest Territories.
