River Rouge has 7 dispensaries licensed by the Michigan Cannabis Regulatory Agency (CRA). Anyone 21 or older with a valid government photo ID can shop, including visitors from other states and countries with a passport.

River Rouge is a small Wayne County city on the Detroit River, just south of Detroit's southwest side, and it punches far above its size in cannabis. Two of its stores, Herbology Cannabis Co and JARS Cannabis, have about 16,000 Google reviews between them. For Downriver shoppers the draw is convenience: the stores sit close together, and three stay open until midnight.
