Transporting marijuana is one of the most dangerous areas of international travel regulations. Even if cannabis is legal in your home state, that does not permit you to take it with you when you fly. Breaking these regulations can lead to severe legal consequences and travel bans.

The foundational truth is that national law still classifies cannabis as a Schedule I controlled substance. This means that no matter how legal it is in California or Colorado, it remains illegal under federal law. This applies every airport in the U.S., which are under federal jurisdiction. You must not transport weed via air—even between two legalized jurisdictions.

Transportation Security Administration staff are not tasked with upholding local cannabis regulations, but they are required to report any illegal substances. If they discover marijuana in your belongings, you might face arrest, even when acting lawfully locally.

Driving with weed between states is also a criminal violation. Carrying a legal amount in your vehicle with a legal amount of weed can result in serious charges. Crossing state lines triggers federal law, and carrying cannabis beyond state boundaries is treated as drug trafficking, even for personal use.

Overseas, the risks escalate dramatically. Most countries have zero tolerance for cannabis, regardless of prescription status. Canadian law permits recreational use, but carrying it into American soil is completely illegal. Similarly, entering the United States with cannabis from Canada or Mexico is illegal and can result in permanent bans from reentry.

In some regions, the consequences are severe, including life sentences or execution for simple possession. Check the legal status before you travel before you travel. Even during layovers, the rules are fully enforced. Never believe that a foreign prescription you're exempt. Virtually no nation accepts out-of-country medical marijuana cards.

If you rely on cannabis for treatment, consult a local physician and explore FDA-approved or locally sanctioned options. Do not bring any marijuana products. If you're flying, keep it entirely behind. Even CBD products with trace amounts of THC can lead to detention or confiscation in strict jurisdictions.

During overland travel, keep Acheter du cannabis en Norvège securely stored and only within the state where it's legal. Never carry it in your vehicle when crossing into a state where it's illegal.

Ultimately, the rules are clear: Cannabis may be permitted in certain states, but travel is governed by a patchwork of laws that don't always align. What’s legal at home can be a criminal offense during transit. When in doubt, leave it behind—your liberty and life are too valuable to gamble.
