Massachusetts may be on the verge of a significant shift in how employers approach marijuana screening. A bill that would narrow the scope of pre-employment cannabis testing has advanced through committee, signaling momentum behind the idea that employers should focus less on past cannabis use and more on current impairment.

House Bill 2179 would prohibit most employers in the Commonwealth from testing applicants for marijuana before extending a conditional offer of employment. Employers could still test post-offer, but a failed result couldn’t be used to deny the job, unless one of the bill’s exceptions applies.

Those exceptions include safety-sensitive roles, positions governed by federal drug testing requirements, or jobs covered by a collective bargaining agreement that mandates testing. For the majority of private-sector roles, cannabis screening as a gatekeeping tool would no longer be permitted.
