The insurance industry publication Business Insurance reported that new drug tests set to hit the market in 2020 are aiming to zero in on marijuana impairment similar to that of an alcohol breathalyzer and could offer employers solutions in the ambiguous landscape of both safety and compliance with federal drug and disability laws.

Impairment from marijuana use is fast becoming a national concern among employers, regulators and other stakeholders in workplace safety, just as drug testing companies and researchers aim to solve a growing concern among employers.

An accurate marijuana breathalyzer could be a “game changer” for employers who are struggling to determine when an employee may have used marijuana — whether it was on the job or off-duty, said Ben Tievsky, senior associate in the New York office of Pillsbury Winthrop Shaw Pittman LLP.

“There are legitimate reasons why employers don’t want marijuana use in the workplace, especially in safety-oriented occupations,” he said.
