Thailand’s cannabis rules are moving toward tighter control after repeated tourist smuggling cases and growing concerns over weak oversight.
From liberalisation to tighter control
Thailand, which in 2022 became the first country in Asia to decriminalise cannabis, is preparing new restrictions after a surge in smuggling attempts by tourists and rising concern over a lack of regulation. The shift marks a clear change in the country’s cannabis rules after a rapid expansion of the market.
The 2022 decision opened thousands of cannabis shops and cafes. It also gave Thailand an image of being liberal and modern, which attracted visitors and farmers interested in cultivation. But as the market grew, criticism intensified. More voices began to argue that cannabis had become too easy to buy and that weak controls were encouraging misuse.
What the new rules may change
Health Minister Somsak Thepsutin has announced that cannabis shops will soon be allowed to sell products only to people with a prescription. That would return cannabis to a medical role rather than leaving it as a widely available recreational product.
Authorities also reminded the public that taking cannabis out of Thailand is illegal. Even so, more tourists continue to try to carry it in luggage. For visitors, the message is simple: cannabis may still be legal for adult use inside the country, but it is not legal to export.
Airport cases and foreign arrests
Airports in Bangkok and on Koh Samui have recorded dozens of smuggling cases. In March, police seized 375 kilograms of cannabis in 22 suitcases belonging to 13 foreigners. British and Indian nationals were among those most often detained.
British media also reported a case of young women who were arrested in Georgia and Sri Lanka after flying there directly from Thailand. In addition, British authorities said that since mid-2024 more than 50 of their citizens have been arrested in Thailand for attempted smuggling.
Why this matters for travellers
The changing cannabis rules are important because they affect both legal use and border enforcement. Travellers should not assume that what is available in Thailand can be carried onto a plane, even if it was purchased legally in-country.
- Use responsibly: cannabis remains legal in Thailand only for in-country use and only for adults.
- Do not risk the airport: export attempts can lead to arrest, deportation and heavy fines.
- Watch for updates: new regulations requiring prescriptions may be introduced in the coming weeks.
For Thailand, the goal appears to be balance: keeping the country attractive and open while making the market safer and more predictable. That could support tourism by reducing uncertainty, even as the street scene in Bangkok and on the islands may change.
For visitors, the practical takeaway is unchanged: enjoy the trip, but do not carry cannabis out of Thailand.
