St. Peters has 6 dispensaries licensed by the Missouri Division of Cannabis Regulation (DCR). Customers have to be 21 or older and show valid photo ID, and you do not need to be a Missouri resident. Every store open here also serves registered medical patients. St. Peters has the most dispensaries in St. Charles County, just ahead of its neighbor O'Fallon.
St. Peters is a suburban, drive-up market: the stores sit on the I-70 outer roads and the arterials around Mid Rivers Mall rather than on a walkable main street. That suits commuters, and one store here, Root 66, keeps its doors open around the clock.
