American workers using marijuana on the job rose to a “historic” high last year, according to a new study.
Diagnostic information service Quest Diagnostics released a report on May 18, analyzing over 6 million employee urine samples in 2022, and found that 4.3 percent of them were positive for cannabis, up from 3.9 percent in 2021.

The study was held following a rise in workplace accidents to their highest level in 25 years last year.
