28 Jun 3. How much marijuana can I purchase in Massachusetts?
The regulations promulgated by the MA CCC state that you may purchase the quantity necessary to treat your qualifying condition. This quantity is determined by your medical marijuana-recommending physician. As a recreational user, you may purchase up to an ounce of marijuana or five grams of marijuana concentrate in a given transaction. That’s the same amount a person can legally possess in public, but you can have up to 10 ounces at home.
