Workers who use marijuana off the clock are no more likely to experience workplace injuries compared to those who don’t consume cannabis at all, according to a new study that challenges “overly broad” zero-tolerance employment policies.
However, people who indulge doing work hours are nearly twice as likely to be involved in a workplace incident than non-users and off-duty users, researchers at the University of Toronto, University at Buffalo and Toronto Rehabilitation Institute found.
The study, published in the Canadian Journal of Public Health on Monday, followed 2,745 Canadian workers in safety-sensitive and non-safety-sensitive positions over two years, analyzing the 11.3 percent of those in the sample who experienced a workplace injury during that time period.
