What were Canadian workers thinking about cannabis use before legalization?

One year ago today, non-medical cannabis was legalized in Canada. Four months before legalization, researchers from the Institute for Work & Health surveyed workers across Canada to find out about their use of, and beliefs about, cannabis at work. These researchers are surveying this same group of workers (and more) for three years post-legalization to find out if their use and beliefs are changing. Some of the findings from the pre-legalization survey are now available in an infographic.
