Massachusetts Marijuana Compliance

Massachusetts Marijuana Laws

Overall Status: Fully Legal

Medical marijuana is legal in the state of Massachusetts for patients with a valid prescription. Recreational marijuana is legal for individuals over the age of 21. However, Massachusetts marijuana compliance rules regulate the amount of marijuana an individual may possess and where they may consume it.

Medical Marijuana: Legal

Medicinal marijuana use has been legal in Massachusetts since January 1, 2013. Under Massachusetts medical marijuana laws, patients with debilitating medical conditions are allowed to possess a 60-day supply of medical marijuana. This is the equivalent of 10 ounces. Medical marijuana is also tax-free, providing a 20% discount versus the cost of recreational marijuana.

Qualifying conditions for a medical marijuana prescription include:

Crohn's disease
Amyotrophic lateral sclerosis (ALS)
Multiple sclerosis
Hepatitis C
Parkinson's disease
Positive status for human immunodeficiency virus
Acquired immune deficiency syndrome (AIDS)
Other debilitating conditions as determined in writing by a qualifying patient's physician

Decriminalized: Yes

In Massachusetts, there are no criminal penalties for adults age 21 and over who possess one ounce or less of marijuana.

However, those who possess more than one ounce may be found guilty of a misdemeanor. The first offense is punishable by up to six months in jail and a maximum fine of $500. For subsequent offenses, the penalty is up to two years of incarceration and a fine of up to $2,000.

Recreational Marijuana: Legal

Recreational marijuana has been legal in the state of Massachusetts for individuals over the age of 21 since December 15, 2016. However, that doesn't mean you can use it whenever you want. Massachusetts' recreational marijuana laws place limits on how much you can possess and where you can consume marijuana.

If you are over age 21, you're allowed to have up to one ounce on you. However, you may only have up to five grams of marijuana concentrate on you at one time. You may also have up to 10 ounces of marijuana in your primary residence and you can grow up to six marijuana plants, or 12 if there are two or more adults residing in the home.

Individuals may not consume marijuana in any form (smoking, eating, or vaping) on federal land or in public. It's illegal to drive under the influence of marijuana and you cannot have an open container of any form of marijuana in the driver or passenger area of your vehicle. If you drive with marijuana in your car, it must be kept in a closed container either locked in your glove compartment or in your trunk.
