Is Cannabis Legal in Maine?

Yes, cannabis is legal in Maine for both medical and recreational use. Adults 21 years or older can possess, use, and grow cannabis. Medical cannabis has been legal in the state since 1999. Patients with qualifying conditions, such as chronic pain, can access cannabis through a licensed dispensary or grow their own plants. 

History of Cannabis Legalization in Maine

Maine has had a long and complicated relationship with cannabis. In the 1970s, the state decriminalized the possession of small amounts of cannabis, becoming one of the first states to decriminalize the drug. 

However, it was not until 1999 that the state legalized cannabis for medical use. In November 2016, voters approved Question 1, legalizing recreational cannabis use, but sales didn’t start until the fall of 2020.
