The UK Home Office has warned young travellers not to ruin their futures by accepting offers of free holidays from criminal networks looking to recruit drug mules.
The warning, issued by Border Force ahead of the peak summer travel season, comes amid an unprecedented surge in cannabis smuggling through UK airports. Organised crime groups are increasingly using social media to target school leavers, university graduates, and first-time holidaymakers.
According to official figures, the number of air passengers caught smuggling cannabis into the UK skyrocketed from 142 in 2023 to 976 in 2025. The crisis has escalated further this year, with 600 couriers arrested at British airports in the first six months of 2026 alone.
The Thailand connection
Border Force revealed that the largest demographic arrested so far this year consists of men aged between 18 and 37 travelling from Thailand.
Cannabis seizures from air passengers reached a record 28 tonnes in 2025—a massive leap from the 2.1 tonnes intercepted just three years earlier in 2022.
To combat the trend, a joint UK-Thailand crackdown has been launched. Under the new initiative, British nationals caught attempting to smuggle cannabis out of Thailand face average fines of about £17,700 and prison sentences of up to two years before even returning to the UK.
Officials noted that while Thailand is a major source country, syndicates are also recruiting couriers from other regions where the drug is legal or easily accessible, including Canada, the United States, and parts of Europe.
Too good to be true
Gangs reportedly entice young targets with promises of business-class flights, luxury accommodation, and thousands of pounds in spending money before coercing them into packing drugs into their suitcases.
“Organised criminal gangs are exploiting young people for profit – living it up while leaving their courier victims facing lifelong consequences,” said Kate Goldstone, the Border Force Lead Officer for Safeguarding. “If an offer feels too good to be true, it probably is.”
As part of a nationwide airport awareness campaign, travellers are being urged to:
- Refuse any offers of free holidays or accommodation from strangers or online acquaintances.
- Maintain strict control of their own passports and luggage.
- Never carry a bag or package on behalf of someone else.
- Remember that importing cannabis into the UK remains a serious crime, regardless of whether it is legal in the country they visited.
The Home Office reminded holidaymakers that anyone caught smuggling cannabis into the country faces arrest, a permanent criminal record, strict future international travel bans, and up to 14 years in prison.
