The New York Times has the dope on cannabis use in Canada

“The percentage of Canadian drivers killed in vehicle crashes who test positive for drugs (40%) now actually exceeds the numbers who test positive for alcohol (33%)”

Seems reasonable that legalisation won’t help this issue. As a cyclist (I rarely drive) this seems like a real fucking problem to me. 40%. Let that sink in. 40%. To be fair, perhaps drugs don’t increase that odds of crashing and killing/dying, and that 40% of Canadians would test positive in a random test.
