A new study finds more than 35 percent of Canadian high school students admit to having been in a car with a driver who had been drinking, while 20 percent reported ever riding with a driver who had been using marijuana.
“These numbers are concerning,” said study author Leia Minaker of the University of Waterloo. “A significant proportion of car-crash deaths are related to alcohol and drug impairment.”
The findings come from a national survey of almost 25,000 students, HealthDay reports. The survey found 9 percent of students in grades 11 and 12 have driven within an hour of drinking. More than 9 percent have driven after having used marijuana.
The findings are published in the Canadian Medical Association Journal Open.
