Two proposed ballot measures that would dismantle Massachusetts’ legal marijuana market have been approved for signature gathering by Secretary of the Commonwealth William Galvin’s office.

The initiatives wouldrepeal key provisions of the state’s 2016 voter-approved legalization law. Both measures would shut down retail marijuana sales and eliminate home cultivation while keeping the state’s medical marijuana program intact. Adults 21 and older could still possess up to one ounce of marijuana—or five grams of concentrates—and sharing without compensation would remain legal. Possession of up to two ounces would be treated as a civil violation, carrying a $100 fine.

One version of the proposal goes further by setting new potency restrictions for medical marijuana. It would bar flower products exceeding 30% THC, concentrates above 60% THC, or more than 5mg THC per metered dose. It also mandates serving-size labeling and limits concentrate packaging to 20 doses.

Supporters can now begin collecting the 74,574 valid signatures required by December 3, 2025, to advance the proposals. If those signatures are verified, the Massachusetts Legislature will have until May 6, 2026, to act. Should lawmakers decline to pass the measures, organizers would need to collect an additional 12,429 signatures by July 1, 2026, to place the proposed laws on the November 2026 ballot.

Massachusetts has generated over $8 billion in adult-use marijuana sales since retail outlets opened in 2018. The proposed initiatives would undo that system entirely, while leaving patients’ access to medical marijuana in place.

Proponents of repealing legalization face an uphill battle: Polling from last year found that 79% of voters believe the state’s legalization law has had a positive impact, with 65% saying it was the right decision (compared to just 22% who said it was the wrong choice).
