Maine Marijuana Law

Updated August 27, 2026

*Legal Disclaimer

Current Status: Legalized

Maine has a long history with marijuana, being one of the first states to decriminalize the possession of small amounts in 1976. Medical marijuana became legalized in the state in 1999, however, it wasn't until 2016 that Maine fully legalized marijuana for recreational use.

Public Consumption Laws

While marijuana is legal in Maine, it is still illegal to consume in public spaces. This includes parks, sidewalks, and other similar areas. Consumption must take place on private property with the permission of the owner.

Cannabis DUI Laws

Maine does not have a strict limit on THC levels, instead the state uses an impairment-based policy, meaning if law enforcement finds you incapable of safely operating a vehicle due to cannabis, you can face harsh penalties. It is important to note that even though recreational use is legal, driving under the influence is still a serious offense.

Cultivation Laws

Maine allows for personal cultivation of up to 3 flowering marijuana plants, 12 immature plants, and unlimited seedlings. However, these plants must be kept out of public view and can only be grown on private property with the owner's permission.

Possession Laws

Individuals over the age of 21 are allowed to possess up to 2.5 ounces of marijuana. Possession of more than this limit can result in fines and/or jail time depending on the amount.
