Toronto, Canada: The enactment of nationwide legislation in Canada legalizing the use of cannabis has had little perceived impact on workplace safety or employees’ performance, according to survey data compiled by the Ipsos market research firm and commissioned the human resources group ADP Canada.
The survey reported: "[R]ecreational cannabis had a smaller-than-expected impact on workplace performance. Most Canadians believe recreational cannabis has had no impact at work in terms of health and safety incidents (75 percent), productivity (74 percent) absenteeism (71 percent) or quality of work (70 percent)."
The findings are in contrast to the perceptions held by Canadians prior to legalization when nearly half presumed that the policy change would be associated with a decline in work quality and productivity and a rise in occupational accidents.
Commenting on the survey results, an ADP Canada representative said, "There was a lot of uncertainty and hype leading up to cannabis legalization last year, but so far, cannabis has not had a noticeable impact on the workplace or on workplace performance."
According to a 2017 literature review by the US National Academy of Sciences, Engineering, and Medicine, "There is no or insufficient evidence to support … a statistical association between cannabis use and … occupational accidents or injuries."
