Massachusetts cannabis events, conventions & dates

Massachusetts has had adult-use retail since 2018, regulated by the Cannabis Control Commission (CCC), and it hosts more recurring cannabis events than most states its size: NECANN's flagship New England Cannabis Convention at Boston's Hynes Convention Center (April 9–10, 2027, confirmed), Flower Expo Massachusetts in Northampton (June 16–17, 2027), Blank Rome's State of the Cannabis Industry Conference in Boston (the tenth edition is October 26, 2026), the Harvest Cup competition and trade show at Worcester's DCU Center (November 13–14, 2026), and the Boston Freedom Rally, MassCann/NORML's reform rally traditionally held on Boston Common in September (the 37th was September 18–19, 2026; the 38th is listed for September 2027).

That mix — a trade convention, a B2B expo, a policy conference and a consumer rally — is what makes a Massachusetts cannabis event calendar worth subscribing to rather than searching for one show at a time. The Massachusetts feed below carries all of them, plus the ballot and federal dates that apply in the state — including Question 8 on November 3, 2026, which would end the adult-use market while letting licensed businesses convert to medical.
