Overview

Maine voters legalized adult-use cannabis in 2016, and licensed retail sales began in 2020. Adults 21+ may possess up to 2.5 ounces and grow plants at home within mature, immature, and seedling limits. The Office of Cannabis Policy regulates both the adult-use and medical programs. Maine's medical program is known for its large network of small caregivers. Municipalities must opt in before adult-use businesses can operate locally.

Penalties

Adult-use cannabis is legal in Maine. Consuming in prohibited public spaces or exceeding possession limits may still result in a civil fine.

Driving and Cannabis

Driving while impaired by cannabis is illegal in Maine, as it is in every state, whether or not the cannabis was obtained legally. Officers may rely on field sobriety tests, drug recognition evaluations, and blood tests, and some states set specific THC limits or zero-tolerance rules. Consuming cannabis in a vehicle and carrying open or unsealed packages where the driver can reach them are commonly prohibited. If you have used cannabis, the safest choice is not to drive.

Crossing State Lines and Federal Law

Taking marijuana across state lines is illegal under federal law, even between two states where cannabis is legal, and it may also violate the law of the state you enter. Marijuana is also prohibited on federal land, in national parks, and at airports under TSA jurisdiction. In 2026 the federal government moved FDA-approved products and state-licensed medical marijuana to Schedule III, but adult-use marijuana remains a Schedule I substance, and rescheduling does not legalize interstate transport. Separate federal changes to the legal definition of hemp take effect in late 2026 and will restrict many intoxicating hemp-derived THC products.
