You cannot use cannabis in any form—including smoking, vaping, or eating—in public places or on federal land.
Keep marijuana in a closed container while on the road.
Just like alcohol, it’s illegal to have an open container of any form of marijuana in the passenger area of a car. An individual may receive a civil penalty of up to $500 for having an open container of marijuana in the passenger area of a vehicle while on the road or at a place where the public has access. Store marijuana in a closed container and place in your trunk or a locked glove compartment.

Don’t mail it.
You cannot send marijuana by mail—even to states and countries where marijuana use is legal.

If you have more than one ounce of cannabis in your home, it must be locked in a secure place. In fact, it’s best to lock away all cannabis-based products in childproof packaging to keep kids and pets safe.

It’s illegal to drive while under the influence of cannabis. Take public transportation, contact a ride-share, or catch a lift with a sober friend.

Out-of-state visitors can purchase marijuana, but…
If you’re visiting from another state, you must be 21 years or older and present a valid government-issued ID to purchase cannabis or cannabis-based products from an adult-use Marijuana Establishment in Massachusetts.
However, you must enjoy your purchase in Massachusetts, since it’s against the law to transport marijuana across state lines—whether it’s by car, plane, train, boat, or any other mode of transportation. It’s also illegal to mail any type of cannabis-based product, including edibles, even if the final destination is a state, territory, or country that has legalized marijuana.
If you’re staying at a hotel or other type of rental accommodation, inquire about marijuana use policies prior to consuming.
