Can I legally travel with cannabis?
You can sometimes travel with cannabis, but legality depends on federal, state, and local rules. Flying with medical cannabis is now allowed in some cases, however nonmedical possession may remain illegal under federal law. Always check departure, transit, and destination laws, and carry medical documentation when required.
Cannabis Travel Laws and Regulations
U.S. rules for travel with cannabis form a confusing patchwork. Federal law still bans cannabis, but 24 states now allow legal adult use. Therefore, you must know which jurisdiction applies to your trip to avoid fines, arrest, or confiscation.
Key points to remember
- Air travel: TSA lists medical marijuana in its What Can I Bring tool, however TSA can refer illegal items to law enforcement. Check the TSA guidance at TSA guidance before flying.
- Driving by land: State laws control road rules, and many states enforce DUI limits. As a result, driving under the influence laws still apply across jurisdictions.
- Crossing state lines: Transporting cannabis across state lines remains illegal under federal law, so never cross borders with cannabis even between legal states.
- Federal land: National Parks and federal facilities prohibit cannabis possession, so avoid use in those areas.
- Private property and rentals: Hotels, campgrounds, and private venues set their own rules and penalties.
- International travel: Do not travel abroad with cannabis; penalties can be severe.
