Impaired Driving by Drugs – Any Detectable Amount

Times Colonist Story by Louise Dickson – Under Canada’s new impaired-driving laws, it’s a criminal offence to have “any detectable amount” of cocaine, methamphetamine, magic mushrooms, LSD, ketamine or PCP in your blood.

“You can do a very careful analysis of blood and detect a minute amount of some drug, but there’s no reason to think that’s connected to driving problems,” said Mulligan, who is concerned that setting the limits at “any detectable level” will result in convictions of people who are not impaired or driving dangerously.
