420 Events in Massachusetts in 2021

Last year, the cannabis community had high hopes for 420 festivals and celebrations. Unfortunately, nearly none of them saw the light of day, thanks to the COVID-19 pandemic and the resulting lockdowns. While some resorted to socially-distanced and virtual events, most in-person events were canceled. Cannabis enthusiasts had to find new and innovative ways to celebrate the year’s most anticipated cannabis holiday. 

A year after the onset of the pandemic, events are still largely uncertain and liable to change as April 20th approaches. Understandably, cannabis users may be reluctant to buy tickets to events that may face cancellation. Most of Massachusetts’ 420 events are postponed or uncertain, so 2021 may be a limited year for in-person events. Virtual events and webinars have risen in popularity in the last year, and cannabis users can celebrate 420 in the comfort of their own homes. Many Massachusettsians are taking advantage of 420 deals and product launches to stock up for a socially distanced good time.

Note: As a response to the ongoing COVID-19 pandemic and lockdown measures, some events may be postponed or canceled. Make sure to stay posted on the details of these events as they draw nearer, and contact the event producer prior to the event with questions or concerns.

At this in-person event, doctors, clinicians, researchers, scientists, and frontline nurses discuss emerging science regarding cannabis-based therapies and treatment. This event features in-depth explorations of the endocannabinoid system and cannabinoids, with insights into the modern applications of cannabis as a viable option to improve patient outcomes.

Using Cannabis in Massachusetts Public Areas

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.
