Massachusetts Cannabis Age and Possession Limits: Visitor Boundaries
Who may buy adult-use cannabis
The Massachusetts Cannabis Control Commission (CCC) says adult-use purchasers must be at least 21 and show government-issued ID at a licensed retailer. Visitors from other states may buy adult-use cannabis under those conditions; medical access is separate.
Public and home limits
The CCC lists up to two ounces carried and up to ten ounces in the home, plus cannabis produced by plants cultivated on the premises. Amounts above two ounces kept at home must be locked in a secure place. The public carry limit is not the home limit.
Visitors and travel boundaries
The CCC says cannabis may not be transported outside Massachusetts by car, plane, train, boat, or other mode. A legal purchase does not authorize interstate transport. Check federal rules separately for federal property.
Vehicle and public-use cautions
The CCC says public cannabis use and driving under the influence are illegal. An open container in the passenger area of a vehicle is unlawful; store it closed in the trunk or a locked glove compartment. This article does not determine when a person is safe to drive.
