The fastest way to ruin a trip is to pack something that's perfectly legal where you live and a serious crime where you land. A prescription in your carry-on, a CBD gummy, a vape, the cash in your wallet — each has put ordinary travelers in handcuffs. Below are the rules that catch people off guard most often, every one with its official government source and the date LawLert verified it. When you're actually planning a trip, check the country page for where you're going.
Cannabis & CBD — legality at home means nothing abroad
A US state legalizing cannabis has no effect once you leave the country, and many places make no distinction between marijuana and CBD or between medical and recreational use. Several countries carry penalties up to life imprisonment or death. Even Canada — where cannabis is legal domestically — treats carrying it across the border as a criminal offense.
- Bangladesh Possessing or importing drugs is illegal in Bangladesh — even medical marijuana with a US prescription. Penalty: Drug offenses can carry long jail sentences, heavy fines, or even death. § US State Dept — Bangladesh

- Cambodia Cambodia has a zero-tolerance drug policy; possession, trafficking, and manufacturing of any illegal drugs — including cannabis, methamphetamine, heroin, and MDMA — are serious offenses even in very small quantities. Penalty: Long jail sentences including life in prison, with no reduction for good behavior. § US State Dept — Cambodia
- Hong Kong Hong Kong has zero tolerance for illegal drugs including marijuana and CBD; CBD is a dangerous drug under the Dangerous Drugs Ordinance. Penalty: Possession or consumption of CBD: up to 7 years imprisonment; trafficking or illicit manufacturing: up to life imprisonment. § Australian DFAT Smartraveller — Hong Kong

Penalty: Non-bailable offense with a maximum penalty of life imprisonment. § US State Dept — Philippines

Prescription medications — your US prescription may not protect you

Vaping — banned in more places than you'd think
Several countries ban the import, sale, or even possession of e-cigarettes and vape liquids entirely — tourists included. A device that's everyday-legal at home can be confiscated, fined, or worse at the border.
- Bangladesh Do not bring e-cigarettes or vaping devices into Bangladesh — the US embassy lists them alongside illegal drugs as items not to bring into the country. § US State Dept — Bangladesh

FAQ
Is it legal to travel with CBD?
Often no. Countries like the UAE, Saudi Arabia, Hong Kong, Malaysia and Indonesia treat CBD the same as marijuana — a US medical card or prescription does not exempt you, and even trace amounts can mean arrest.
Can I bring my prescription medication into another country?
Not always. Some common US prescriptions — including Adderall and other amphetamine stimulants, and cold medicines with pseudoephedrine — are banned outright in countries like Japan, even with a valid US prescription. Always check the destination's rules before you fly.
Is my US state's legal cannabis valid abroad?
No. Legality in your home state has no bearing once you leave the US. Many countries prohibit cannabis entirely — several with penalties up to life imprisonment or death — and carrying it across a border (even into Canada, where it's legal domestically) is a serious offense.
How much cash can I travel with internationally?
Most countries require you to declare cash or monetary instruments at or above a threshold — commonly about US$10,000 (limits vary by country). Failing to declare can bring fines or seizure, on both entry and exit.
