The Foreign, Commonwealth and Development Office (FCDO) has issued a renewed warning to British travellers after individuals were caught attempting to take cannabis out of Thailand. The advisory underscores that exporting cannabis from the country is illegal and carries serious consequences, including arrest and hefty fines.
Strict Enforcement at Airports
The FCDO stated: "British nationals have been caught carrying cannabis out of Thailand, including while travelling through other countries. Many international airports have advanced security technology that can detect illegal items, even in the luggage of transit passengers. If you are caught, you could be arrested or fined." This serves as a stark reminder that airport customs worldwide employ sophisticated scanning equipment capable of identifying prohibited substances.
Thailand's Cannabis Laws
Although Thailand decriminalised cannabis in 2022, the legal landscape has since tightened. Cannabis remains legal only for medical use, requiring a valid doctor's prescription for purchase or consumption. Recreational use is strictly banned, and exporting cannabis is prohibited under any circumstances. Violators face fines starting at THB 30,000 per kilogram and potential imprisonment.
Regional Travel Advisories
The FCDO also advises against all but essential travel to several areas in southern Thailand near the Malaysian border. This includes the provinces of Pattani, Yala, and Narathiwat, as well as the districts of Chana, Thepa, Na Thawi, and Saba Yoi in Songkhla province. The warning extends to the Hat Yai to Padang Besar train line, which traverses these regions, due to frequent attacks near the border.
Additionally, travellers are cautioned to avoid the Thailand-Cambodia border, where fighting has occurred. Land border crossings remain closed, and several tourist attractions near the border are shut. There is also a risk from unexploded landmines in certain areas.
UK Law and Penalties
Under UK law, cannabis is a Class B controlled substance. Importing it into the UK is illegal and carries a maximum penalty of up to 14 years in prison. The FCDO explicitly prohibits the importation of cannabis, and British nationals caught doing so face severe legal repercussions both in Thailand and upon return to the UK.
Tourism Recovery
In 2025, Thailand welcomed over 1 million British visitors for the first time since the Covid-19 pandemic, as holidaymakers flock to the country for its warm weather, street food, and vibrant culture. The FCDO's advisory aims to ensure that travellers remain aware of local laws and avoid actions that could lead to legal trouble or endanger their safety.
