Massachusetts Marijuana Laws (2026 Update)

Yes, marijuana is legal in Massachusetts as of 2026. The state has legalized both medical and recreational cannabis. Medical marijuana became legal in 2012 under Chapter 369 of the Acts of 2012 (An Act for the Humanitarian Medical Use of Marijuana). Recreational cannabis was legalized via a 2016 ballot initiative, with regulated retail sales launching in 2018. There are still regulations and restrictions regarding cultivation, sale, and distribution.

In Massachusetts, individuals 21 years of age or older can legally possess up to one ounce (28.5 grams) of marijuana in public and up to ten ounces (283.5 grams) in their residence. Possession of marijuana by individuals under the age of 21 is still illegal.

Massachusetts allows individuals to cultivate marijuana for personal use. Adults 21 and older can grow up to six marijuana plants per person, with a maximum of 12 plants per household. The plants must be grown in a secure and enclosed area that is not visible to the public.

While marijuana is legal in Massachusetts, there are still penalties for certain violations. Possession of more than one ounce but less than two ounces is a civil offense punishable by a fine of up to $100. Possession of more than two ounces is a criminal offense that can result in imprisonment for up to six months and a fine of up to $200.

In Massachusetts, medical marijuana can be recommended by physicians, Certified Nurse Practitioners (CNPs), and Physician Assistants (PAs) who are certified by the Cannabis Control Commission (CCC). Patients with qualifying medical conditions can obtain a medical marijuana card through the Massachusetts Medical Use of Marijuana Program, allowing them to purchase and use marijuana for medical purposes.
