According to an analysis by Quest Diagnostics released last Thursday, the percentage of the general U.S. workforce who tested positive for marijuana in their urine after having an accident at work rose to 7.3% in 2017. It was 6.7% in 2021, a tad less. Remember, these are only tests done after a worker had an accident, if you didn’t have an accident, and were high on cannabis, it would not be recorded in this survey.
