The federal authorities doesn’t plan on altering the authorized THC restrict for drivers, even after a B.C. research that steered no connection between now-illegal quantities of the compound and danger of crashing.

A College of B.C. research, revealed in June within the journal Addictions, checked out THC quantities in blood samples from greater than 3,000 individuals who had been injured behind the wheel.

Of the 1,825 drivers deemed accountable in crashes, researchers discovered that drivers with lower than 5 nanograms of THC, the psychoactive ingredient in cannabis, per millilitre of blood had no elevated danger of crashing.

Canadians legal guidelines make driving with between two and 5 nanograms per millilitre a abstract offence with a fantastic as much as $1,000.

Having extra 5 or extra nanograms has a minimal fantastic of $1,000 and a max sentence of 10 years in jail for the primary offence.

Researchers weren’t ready decide if greater than 5 nanograms elevated the chance of crashing as a result of solely 20 drivers had that a lot, an inconclusive pattern.

A spokesperson for federal Justice Division instructed Black Press Media that cannabis driving legal guidelines had been “primarily based on robust and indeniable proof that cannabis is an impairing drug.”

“The prohibited ranges additionally consider the method taken in different jurisdictions, together with jurisdictions the place cannabis has been legalized,” spokesperson Ian McLeod mentioned in an electronic mail.

The fines for two nanograms or much less are a “a precautionary method making an allowance for the very best accessible scientific proof associated to THC,” whereas the 5 nanogram quantity signifies latest use, McLeod mentioned.

Based on UBC researcheres, THC ranges peak above 100 nanograms per millilitre inside 15 minutes of smoking pot after which drop to 2 nanograms or much less throughout the subsequent 4 hours.

Ranges of THC take about eight hours to drop to 2 nanograms or much less after consuming cannabis.
