- **Can tourists buy:** Allowed with conditions.

- **Overview of United States (not a local permission):** Einen legalen Verkauf an Erwachsene gibt es nur in den Bundesstaaten und Territorien, die tatsächlich einen Freizeitmarkt gestartet haben, nicht landesweit. Dort können Touristen ab 21 Jahren in der Regel in einer lizenzierten Abgabestelle mit einem gültigen amtlichen Ausweis oder Reisepass kaufen. Cannabis bleibt auf Bundesebene kontrolliert, du darfst das Produkt also nicht über Bundesstaatsgrenzen oder internationale Grenzen transportieren.
