7 things to know about Massachusetts's medical marijuana program
The Massachusetts Medical Use of Marijuana Program is run by the Cannabis Control Commission. Adult Massachusetts residents get certified by a registered physician, nurse practitioner or physician assistant. The patient then receives a PIN by email and completes registration in the state's online system. Registration is free, but patients must renew every year. The law names conditions such as cancer, glaucoma, HIV/AIDS, hepatitis C, ALS, Crohn's, Parkinson's and MS, and providers may also certify other debilitating conditions in writing. Patients may have a 60-day supply (10 ounces) and pay no marijuana excise or sales tax. Out-of-state cards are not accepted.
