The Short Answer: Yes, Cannabis Is Fully Legal
Cannabis is legal in Massachusetts for adults 21 and older. On November 8, 2016, voters approved Question 4 with 53.59% support, making Massachusetts the first state east of the Mississippi to legalize recreational cannabis. The first recreational sales began on November 20, 2018, at NETA in Northampton and Cultivate in Leicester — generating $2.2 million in the first week alone.
Massachusetts's cannabis journey spans three ballot initiatives across eight years, each building on the last: Question 2 (2008, decriminalization), Question 3 (2012, medical), and Question 4 (2016, recreational). Together they reflect a steady shift in public opinion from 65% support for decrim to full legalization.
