The UK Home Office has warned young travelers against accepting offers of free holidays or luxury trips from criminal gangs seeking to recruit drug couriers.
In an advisory issued on July 17, 2026, Border Force said organized crime groups are increasingly targeting school and university leavers, first-time travelers and young holidaymakers through social media, particularly during the peak summer travel season.
The Home Office said cannabis smuggling through UK airports has risen sharply, with the number of air passengers intercepted carrying the drug increasing from 142 in 2023 to 976 in 2025. In the first half of 2026 alone, 600 suspected couriers were arrested, with men aged 18 to 37 travelling from Thailand accounting for the largest group.
According to Border Force, criminal networks lure victims with promises of free luxury holidays, business-class flights and spending money before persuading or coercing them into transporting cannabis into the UK.
As part of a nationwide awareness campaign, travelers have been advised to reject offers of free travel or accommodation, especially to destinations where cannabis is legal, including Thailand, Canada and parts of the United States. The agency also urged passengers to pack their own luggage, avoid carrying bags for others, ignore suspicious social media approaches and retain control of their travel documents.
Border Force Lead Officer for Safeguarding, Kate Goldstone, warned that accepting such offers could have life-changing consequences.
“Our message to young travellers is simple. If an offer feels too good to be true, it probably is. A single decision made before a holiday could lead to a criminal record, a prison sentence and years of lost opportunities,” she said.
The agency warned that anyone caught smuggling cannabis into the UK could face arrest, prosecution, a criminal record and up to 14 years in prison, alongside restrictions on future international travel that could affect employment and education opportunities.
Border Force said cannabis seizures at UK airports have reached record levels, rising by 50 per cent over the past year. Seizures from air passengers increased from 2.1 tons in 2022 to more than 28 tons in 2025. Although Thailand has emerged as a major source country, officials said criminal networks also operate in Canada, the United States and parts of Europe.
The warning comes as the UK and Thailand implement a joint crackdown on cannabis smuggling. Under the initiative, British nationals caught attempting to smuggle cannabis from Thailand face average fines of about £17,700 or prison sentences of up to two years. Border Force urged anyone approached to transport illegal drugs to report the matter to local authorities, consular officials or Crimestoppers.
