Cannabis is legal to all adults over 21 in Massachusetts. Any adult may cultivate up to six plants at home, or up to 12 plants in a household of two or more adults. Registered patients are exempt from the taxes levied cannabis products for adult-use consumers. Patients may possess up to 10 ounces of cannabis or 1.5 ounces of concentrates in public. Massachusetts dispensaries do not honor out of state medical cannabis cards. Some protections for patients began January 1, 2013, including limited rights to cultivate their own medicine, and the Department of Health (DOH) began issuing ID cards for patients and granting licenses for medical dispensaries in 2014. Massachusetts still does not provide patient protections in the area of housing. Details on how these laws apply to patients and medical professionals can be found below.

In 2018, Massachusetts Governor Charlie Baker signed legislation, expunging the criminal records of those convicted of certain prior marijuana offenses. Any recorded offense that is no longer a crime is eligible to be sealed, with the exception of cases in which the offense or elements of the offense are still considered a punishable crime under a separate designation. For more information, refer to Massachusetts title section 100A and Bill S 2371.
