South Portland has 21 dispensaries licensed by the Maine Office of Cannabis Policy (OCP). Any adult 21 or older with a valid photo ID can shop at its adult-use stores, and out-of-state visitors buy on the same terms as Mainers. 9 stores serve certified medical patients. South Portland was among the first Maine cities to write zoning and licensing rules for adult-use cannabis businesses, voting in 2017 while many towns were still waiting.
South Portland is a separate city from Portland, across the Fore River, and its cannabis market looks different. Instead of a walkable downtown strip, most adult-use stores sit along the retail roads around the Maine Mall, where parking is easy and the stores are big. South Portland also has some of the most reviewed stores in the state: three of them have more than 600 Google reviews each.

Each purchase is capped at 2.5 ounces, and no more than 10 grams of that may be concentrate.

Mall parking lots, Willard Beach and the Greenbelt trail are not private homes, and public use is a civil violation with a fine of up to $100. No one in a vehicle on a public way may consume cannabis, and driving impaired is OUI. Maine has no consumption lounges. Read our Maine marijuana law guide for the full rules.
