Learn the Laws

Marijuana use in Maine is legal. But that doesn't mean you can use it anywhere you want.

Don't buy or sell recreational marijuana

It is not currently legal to buy or sell recreational marijuana in Maine.

You must be over 21

In order to possess or use recreational marijuana in Maine, you must have a valid ID proving you’re 21 or older. It’s that simple.

Don't share marijuana with those under 21

It's a felony to give or share marijuana with someone younger than 21 years old. This includes family members and friends.

Don't use in public

Using marijuana in any form (smoking, eating or vaping) isn’t allowed in public places, including amusement parks, ski resorts, sporting and music venues, state and national parks, campsites, playgrounds, sidewalks and roads, marijuana retail businesses, bars, restaurants and outdoor or rooftop cafes.

So where can you use it? Marijuana use is legal within the confines of private property. Just keep in mind that property owners, landlords, and rental companies can ban the use and possession of marijuana on their premises.

Federal land is under federal law

Marijuana is legal by state of Maine law. Federally, it is not legal. If you’re on federal land, such as a national park or a national forest, you can’t even have it in your possession.

Don't cross state lines

It's illegal to leave Maine with any marijuana products. Mailing marijuana from Maine is also illegal.

Don't drive high

It’s illegal to drive under the influence of marijuana. You could be charged with a DUI. 

Purchasing and transporting

Adults over the age of 21 can possess up to 2.5 ounces of marijuana, including 5 grams of marijuana concentrate. It is illegal to open and use marijuana in a vehicle. This goes for both the passenger and the driver. Keep it sealed.

There's a limit to how much you can grow

Mainers can grow marijuana for personal use. Up to twelve plants are allowed per resident over the age of 21, with as many as six mature and twelve immature, plus unlimited seedlings. Individuals may possess an additional six immature plants if local ordinance permits but the number must not exceed twelve total plants. Be sure to check your local laws for specific details.

Note: Next year, this law is expected to change to three mature plants, twelve immature plants and unlimited seedlings.

Keep it out of sight

An adult who chooses to grow plants at home must make sure the marijuana is not visible from a public way without the use of binoculars.

Only medical patients can buy medical marijuana in Maine

Patients with qualifying medical conditions can receive a registry identification card for legal access to medical marijuana. Cards are available to Maine residents and valid only in Maine. See Maine Medical Use Marijuana Program for more information.

If pregnant or breastfeeding, talk to your doctor

There is no known safe amount of marijuana use while pregnant or breastfeeding. See more information on our pregnant and breastfeeding page.

Talk to a probation officer.

For individuals on probation, there are rules and restrictions for marijuana that must be followed. Contact a probation officer to find out more.
