Documented marijuana-related traffic accidents that required treatment in an emergency room rose 475% between 2010 and 2021, the study found.
Just after Canadian legalization in 2018, when marijuana stores and products were limited, researchers found a 94% increase in emergency room visits, Myran said.
Car crashes involving weed were serious.
Another issue is the rising potency of cannabis, Myran said.
Canada’s lower-risk cannabis guidelines recommend not driving for at least 6 hours after using cannabis and avoiding cannabis and alcohol together.
