With marijuana legalization expected July 1st, police officers will be equipped with devices to test saliva for recent drug use.
SGI's executive vice president, Earl Cameron, said the rule of thumb is not to drive after consuming any drug - legal or illegal.
"Certainly we're not telling people that they're okay to drive," he said. "I think MADD is saying after you've consumed cannabis, you should wait at least four hours. The medical community, public health, is saying five hours. Again, the issue with that is how much have you consumed, and what was the content of that drug?"
Cameron hopes the zero-tolerance approach the province is adopting towards drug-impaired driving will act as a deterrent.
"The whole goal of it is hopefully they don't have to use those devices because people are not driving after they've used drugs - whether they're legal drugs or illegal drugs. And hopefully that's a good deterrent, and people will say, 'well there's a good chance I'll be stopped and checked, so I'm not going to.'"
A failed breathalyzer test or saliva sample isn't needed for punative measures. A driver (experienced, and a first-time offender) can still be penalized with a three-day license suspension, a three-day vehicle impoundment, demerit points, and enrollment in a course on non-impaired driving, for impairment by drugs or alcohol based off a police officer's judgement.
