The growing acceptance of cannabis for medical and recreational purposes raises potential issues for workplaces, especially in roles such as commercial driving, heavy equipment operation and other safety-sensitive jobs that require a high degree of cognitive response.
There are eight U.S. states, so far, that allow recreational use of cannabis. Neighboring Canada now allows cannabis use nationwide. But there are no scientific or legally accepted measures of impairment available yet, which makes organizational policies tricky. Just as workplaces have navigated the issue of alcohol use from an absolute “don’t” to guidelines that prohibit impairment, companies might need to make similar adjustments to accommodate allowable cannabis use.
