On Friday Operation Nez Rouge will begin its 35th year providing Quebecers a safe drive home after a little too much holiday cheer.
Last year, nearly 40,000 volunteers completed more than 53,000 safe rides home in Quebec alone. The service is available in six other provinces.
While last year was a busy holiday season for volunteers, this year could be the busiest yet thanks to the legalization of recreational marijuana.
"We rely on volunteers and it’s especially important they sign up, especially with the legalization of cannabis,” Nez Rouge's David Latouche told CTV Montreal.
The good news is that early data shows the province has not seen a spike in impaired driving arrests since pot day in Canada. The bad news is, there could be more, they're just not being caught.
A recent Stats Canada survey found one in seven cannabis users admit to getting behind the wheel within two hours of getting high.
Researchers at McGill University found those who do drive stoned are significantly more at risk of having an accident, with affects lasting up to five hours.
“We did see the participants in a different task had slower reaction time and weren’t precise in their actions,” said Dr. Isabelle Gelinas.
Quebec has a zero tolerance approach to driving under the influence of marijuana.
Nez Rouge will be offering free rides home, no questions asked, starting November 30 until January 1.

You can sign up to be a volunteer (they need them) here.
