MA S98

Prohibits employers from refusing to hire, firing, or discriminating against employees based solely on the presence of THC or marijuana metabolites in drug tests

Employers may still take action if there is reasonable suspicion the employee was impaired by marijuana at the workplace or during work hours

Defines "safety sensitive position" as a job where impairment could cause immediate, permanent physical injury or death to oneself or others

Exempts safety sensitive positions and situations where compliance would violate federal law, regulations, contracts, or funding agreements

Allows employers a defense if THC presence causes an employee to lose licenses or credentials necessary for their job
