Adult use

Marijuana is legal in Massachusetts for people 21 and older, but that doesn’t mean you can use it anywhere you want.  Here are some basics about the law:

  • You can’t use marijuana in any form (smoking, vaping, edibles, etc.) in public or on federal land
  • You can have up to 1 oz on you and up to 10 oz in your home
  • You can grow up to 6 plants in your home, and up to 12 plants for 2 or more adults
  • If you have more than 1 oz of marijuana in your home, it has to be locked up. But it’s best to keep any amount locked away to keep kids and pets safe.
  • Like alcohol, you can’t have an open container of any form of marijuana in the passenger area of your car while on the road or at a place where the public has access. It must be stored in a closed container in your trunk or a locked glove compartment.
  • It’s illegal to drive under the influence of marijuana. If you use, don't get behind the wheel. Instead, use public transportation, ride-shares, or catch a ride with a sober friend.
  • Employers, landlords, cities, and towns may have their own policies about the use of marijuana. Check with them to see what is legal.

For more information about the regulations that govern what you can and can’t do, how much you can grow and have, and when and where it’s okay to use, visit the Cannabis Control Commission.
