Can I Fly With This?
Can I bring marijuana on a plane?
Quick rules for flying with marijuana in carry-on and checked baggage. Verdicts and conditions across the major aviation regions below.
🇺🇸 United States (TSA)
Federally illegal in the US, including on domestic flights between states where it's legal. TSA does not search for it but is required to report findings to law enforcement.
🇪🇺 European Union (EASA)
Banned. Illegal to fly with regardless of departure or destination country.
🇬🇧 United Kingdom (CAA)
Banned. Class B controlled drug in UK — possession is a criminal offence (up to 5 years prison, unlimited fine). Medical cannabis on UK prescription only. Do not fly with cannabis to/from the UK.
🌎 Latin America
Illegal to fly with in nearly all of Latin America. Uruguay has legal residential use; Mexico has decriminalized personal possession but flying with it remains illegal. Penalties elsewhere range from heavy fines to multi-year prison sentences (especially in Caribbean countries and Central America). Do not risk it.
🌏 Asia (ICAO / IATA baseline)
DO NOT travel with cannabis anywhere in Asia. Singapore, Malaysia, Indonesia: trafficking over the threshold weight carries the DEATH PENALTY; possession alone means years in prison. Philippines, Japan, South Korea, China, Vietnam, Thailand: multi-year prison sentences for any amount. Thailand briefly legalized recreational use in 2022 but recriminalized in 2025 — possession is again an offence. Edibles, vape carts, and CBD that contains any THC are all treated as cannabis. Even transit through these countries with a US/Canadian medical card has led to arrest.
🇦🇺 Australia & Pacific (CASA)
Illegal recreationally across Australia, NZ and the Pacific. Australia: ACT decriminalized small personal amounts but flying with it remains a federal offence. Medical cannabis: only with a current Australian prescription, in original pharmacy packaging, with a doctor's letter — declare on arrival. NZ: medical-only with prescription. Do not bring cannabis from overseas under any circumstances — Australian Border Force routinely prosecutes.
