An Act prohibiting employment discrimination based on the legal use of cannabis

HD 620 prohibits Massachusetts employers from discriminating against employees or job applicants based on their legal use of cannabis. It requires employers to wait until after making a conditional job offer before testing for marijuana and bans conditioning employment on such testing. The law protects qualifying patients (those legally using medical cannabis under state law) from adverse actions like termination or refusal of hire, unless impairment occurred at work or during work hours. Exceptions apply for safety-sensitive roles (where impairment could cause serious harm) and when federal law would be violated.
