28 Jun 3. How much marijuana can I purchase?
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.
