The number of young British nationals arrested abroad after being recruited as drug mules has more than quadrupled over three years, with figures showing a steep rise from just over 80 arrests in 2023 to more than 340 in 2025. This increase is primarily driven by cannabis-related offenses linked to Thailand and other parts of Southeast Asia.
Foreign Office minister Stephen Doughty highlighted that individuals are lured by gangs with promises of "free travel or a quick way to make cash," and warned of severe consequences if detained abroad. These penalties can include lengthy prison sentences, fines, corporal punishment, and in some countries, the death penalty. Doughty emphasized that "no holiday, payment or opportunity is worth risking your freedom, your future or your life."
A BBC investigation earlier this year revealed that Thailand-based drug gangs recruit individuals to transport large quantities of cannabis in suitcases, sometimes misrepresenting the contents as clothing, gold, or cash. Some suitcases have been found to contain up to 71kg of cannabis. In the UK, cannabis is a Class B drug, carrying penalties of up to five years in prison for possession and up to 14 years for supply and production, along with unlimited fines.
The Foreign Office reported that over 200 British nationals have been detained on suspicion of smuggling cannabis from Thailand. Since 2024, approximately 60% of these detainees have been between the ages of 16 and 20. Social media is a common recruitment platform, with young people often incentivized to carry luggage without knowing its contents. Research commissioned by the Foreign Office indicated that a third of young Britons surveyed do not consider carrying luggage packed by someone else to be a risk.
Smuggling from Malaysia, Laos, and Cambodia has also been identified as common sources by the UK government. In July, the National Crime Agency announced that British "mules" caught smuggling cannabis from Thailand would face prison and a fine of 30,000 Baht (£680) per kilogram to leave the country. As of 2026, the Foreign Office stated there have been over 160 cases of British nationals arrested overseas for drug smuggling offenses.
