Massachusetts Marijuana Laws
Marijuana laws in Massachusetts have undergone significant changes since 2012 when sixty-three percent of voters approved an initiative authorizing medical marijuana in the state. Under this law, doctors can provide patients with letters certifying them to use, possess, and grow up to a sixty-day supply of the drug, defined by state regulators as ten ounces.
The law took effect on January 1, 2013. It eliminates statewide criminal and civil penalties related to the possession and use of up to a sixty-day supply of cannabis by qualified patients who possess a "valid registration card" issued by the state. Patients must possess a recommendation from a physician attesting that cannabis assists with the treatment of a "debilitating medical condition."
A few years later, in November 2016, Massachusetts voters again changed the law by passing a ballot initiative legalizing the recreational use of marijuana. The law is effective as of December 15, 2016, and it authorizes adults (21 years of age or older) to possess up to 1 ounce of marijuana outside of their residence and up to 10 ounces within their residences. Adults are also authorized to grow up to 6 marijuana plants in their residences and to give up to 1 ounce of marijuana to another adult without payment.
