New England Cannabis Events Calendar
Cannabis and cultivation events across New England
Trade shows, competitions, conferences, regulator meetings and grower-facing farm and garden events across Massachusetts, Connecticut, Rhode Island, Maine, New Hampshire and Vermont. Filter by state, then tap any event to see what it is, who is running it, who will be there, the address, and a link straight to the organizer's own page.
Every listing here was checked against the organizer's own page or an official calendar on the date shown in its details. We do not list an event we could not verify, and where a date is published without enough certainty we label it rather than present it as settled. Always confirm the date, time and address with the organizer before you travel — dates move, and we are not the organizer.

November 2026
Massachusetts votes on Tuesday, November 3, and Question 8 is on the ballot. The state's own summary says it would repeal the laws that legalize, regulate and tax the retail sale of adult recreational marijuana, taking effect January 1, 2028. In the official wording, a YES vote “would prohibit the legalization, regulation, and taxation of the retail sale of adult recreational use marijuana, and change the penalties for possession of marijuana”, and a NO vote “would make no change to the law relative to marijuana”. To be straight with you about what it does and does not do: possessing an ounce or less stays legal either way, and the medical program keeps running. What goes away is the licensed recreational retail market — the shops, the jobs and the growers and suppliers built around it, which includes a lot of our customers and a lot of our neighbors. That is why we are asking you to vote NO on 8.
- When
- Tuesday, November 3, 2026 · Polls open 7:00 AM – 8:00 PM

Note: Question 8 is one of nine questions on the November 3 ballot, and polls are open 7 a.m. to 8 p.m. statewide. Both sides have registered ballot committees — Coalition for a Healthy Massachusetts is campaigning for a YES vote, Stop the Repeal for a NO vote — and the state's voter guide prints both official arguments alongside the summary.

The Harvest Cup has run since 2017 and is the closest thing New England has to a home cup — a judged cannabis competition wrapped in a two-day exhibition and trade show at the DCU Center.

A large consumer flower and garden show in its 44th-plus year, filling the Hartford convention center with display gardens, plant and seed vendors, and gardening seminars.

Vermont's statewide farm show returns after a multi-year break, with equipment vendors, exhibitors and educational programming for commercial and home growers. It is a general farm and garden show rather than a cannabis event, but it is the kind of gathering serious growers travel for.

June 2027
A B2B cannabis trade show for cultivators, processors, and retailers held at the Three County Fairgrounds in the Pioneer Valley. It focuses on industry networking and product sourcing rather than a consumer festival, so it's best suited to commercial growers and buyers rather than casual visitors.

Rhode Island joins the NECANN circuit for the first time in 2027, bringing the same licensed-market B2B format NECANN runs in Boston and Atlantic City to Providence.

Know about an event that isn't here?
Send it over and we will check it and add it. Call 508-296-0470 or send us a message with the date, venue, organizer and a link. Organizers are welcome to submit their own events the same way. Grassroots gatherings, bonfires, farm days and swaps are exactly what we want — they are the hardest ones to find and the ones worth going to.
Our own events
Free grow classes every Saturday at the Webster store, a monthly mushroom class, and Free Clone Fridays at both stores — all of it is on our store events calendar. Our four big days of the year are listed above alongside everything else.
We are in Webster seven days a week and Milford Monday through Saturday.
