According to data published in the journal titled Occupational Medicine, workers with a history of cannabis use over the past year are no more likely than non-users to experience an injury at work.
Using the work history of a population-based sample of over 136,500 Canadian workers, researchers from the University of Toronto Department of Occupational Medicine accessed the use of cannabis by those workers during the past year and work-related injuries. They identified no association between past-year cannabis use and work-related injury for employees in any occupation, including those who worked in high injury risk occupations. Instead, they actually found a higher risk of workplace injury occuring in workers who were male and under 39 years of age.
Authors concluded: “To the best of our knowledge, this was the largest population-based cross-sectional study examining the association between past-year cannabis use and work-related injuries. We found that workers reporting using cannabis more than once in the past year were no more likely to report having experienced a work-related injury over the same time period in a large cohort of the Canadian working population.”
Their conclusions are similar to those of other studies, finding that adults who consume cannabis in their off-hours are no more likely to suffer injuries at work than are those employees who don’t use cannabis at all. A pair of researchers from San Diego State University in California and Auburn University in Alabama compiled data from 281 employees and their direct supervisors on the topic of marijuana use and job performance. Authors reported that an employee’s cannabis use either immediately before or during work hours was associated with “counterproductive work behaviors,” whereas “after-work cannabis use was not related (positively or negatively) to any form of performance as rated by the user’s direct supervisor.” Authors concluded, “[C]ontrary to commonly held assumptions, not all forms of cannabis use harmed performance. In fact, after-work cannabis use did not relate to any of the workplace performance dimensions. This finding casts doubt on some stereotypes of cannabis users and suggests a need for further methodological and theoretical development in the field of substance use.”
While these studies and others show that cannabis has no effect on work safety or production, alcohol has been proven to have a strong impact on both.
