Flying with cannabis is risky and often illegal—even if cannabis is legal in both your origin and destination. Under U.S. federal code, marijuana remains an illegal drug, meaning it is banned nationwide. This rule covers all U.S. terminals, even in recreational marijuana states. TSA screens all luggage under federal jurisdiction, and TSA personnel must notify law enforcement of contraband.
Even if marijuana is legal where you’re going, you are prohibited from carrying it onto a flight. Every type of marijuana product, from capsules to concentrates, is prohibited. Global rules are just as strict. Nearly every country outlaws cannabis importation, and bringing it across borders—even in small amounts can result in arrest, heavy fines, or imprisonment.
Some travelers mistakenly believe that hiding cannabis in checked luggage or carry-ons will keep them safe. While TSA does not actively seek out marijuana, if found by any security protocol, they must report it to police. A state-issued card doesn’t override federal law.
If your treatment involves medical marijuana, plan ahead diligently. Confirm if your ailment qualifies under local regulations, and see if licensed dispensaries serve visitors. A few jurisdictions honor out-of-state medical cards, but you cannot count on it. It is far safer to purchase cannabis at your destination through licensed dispensaries.
Airline policies also strictly prohibit cannabis, even in states where it’s legal. Noncompliance can trigger immediate removal from travel plans, and may result in future travel restrictions.
Crossing borders with cannabis is exponentially more dangerous. Customs officials in many countries have zero tolerance, and penalties are severe. Even countries that allow personal cannabis use often ban importation.
The safest approach is to leave cannabis at home. If you depend on it for treatment, explore non-Weltkarte Cannabis treatment options that are accepted internationally. Confirm rules for layover locations, including any connecting airports, because local laws differ by city or state.
Respect the boundaries of controlled substance regulations. When in doubt, don’t risk it.
