On June 21st, 2017, after considering 118 amendments, the House passed sweeping legislation (H.3768) by a vote of 126 to 28 refining the laws governing the legalization of adult-use cannabis.

The voters approved the adult use of recreational marijuana by way of a ballot initiative in November of 2016. A new legislative session began in January of 2017 and shortly thereafter came the announcement of a new committee aimed at addressing issues relative to marijuana use. The Joint Committee on Marijuana Policy, chaired by Representative Mark Cusack of Braintree and Senator Patricia Jehlen of Somerville, held hearings across the state, eliciting public feedback on 27 bills relative to marijuana policy and changes to the language of the ballot initiative before reporting out bills to the Senate and House on June 19th, 2017.
