Waterville has 14 dispensaries licensed by the Maine Office of Cannabis Policy (OCP). Adults 21 and older with a valid photo ID, including Colby students who are of age and out-of-state visitors, can shop at the city's adult-use stores. 9 Waterville stores serve certified medical patients. The city's ordinance keeps cannabis retail in certain commercial and industrial zones, which helps explain why so many stores share one short stretch of College Avenue.
That stretch is Waterville's cannabis block. Between 68 and 87 College Avenue you will find five store listings within a few doors of each other, more than many Maine towns have in total. Everything else is a short drive away on Main Street downtown, Kennedy Memorial Drive or Industrial Street, so a Waterville trip rarely takes more than one stop.
