Maastricht has 19 active shops and has long been a destination for visitors from across the nearby Belgian and German borders. The city strictly enforces a residents-only rule: coffeeshops ask for Dutch ID and do not sell to non-residents. Smartshops and headshops in the center and the Wyck district are open to everyone. Most shops open between 10:00 and 20:00, with a few extending to 22:00 on Friday and Saturday. Below is the ranked Maastricht directory.
