Since 2014, the New England Cannabis Convention (NECANN) events have been mainstays of the Massachusetts cannabis industry. NECANN’s convention is one of the nation’s biggest attractions for cannabis, hemp, medical, and CBD industry professionals, and welcomes consumers, patients, vendors, cannabis professionals, entrepreneurs, cultivators and investors.


As it currently stands, public use of cannabis in Massachusetts is illegal. Users can possess up to an ounce of cannabis on their person, but combusting, inhaling, eating, drinking, or vaping cannabis is prohibited in public places. That said, hosting members-only events, private events, and events that require a ticket may have their own cannabis-friendly rules and are subject to a legal loophole. Before using cannabis at any event, be sure to research the cannabis policy to ensure you are not breaking any laws, and that the host tolerates the use of cannabis. 76% of cannabis events are consumption-free, and support cannabis education, entrepreneurialism, and culture.
