The United Kingdom (UK) has warned young travellers not to accept free holidays or luxury trips offered by criminal gangs seeking to recruit drug couriers.
The UK Home Office published the warning on Friday on its official website. It was issued by Border Force ahead of the peak summer holiday season, following a quick rise in cannabis smuggling through UK airports, with organised crime groups increasingly targeting school and university leavers, first-time travellers and young holidaymakers through social media.
According to the Home Office, the number of cannabis smugglers intercepted on arrival in the UK by air increased from 142 in 2023 to 976 in 2025.
In the first six months of 2026 alone, 600 air passenger couriers were arrested at UK airports, with men aged between 18 and 37 travelling from Thailand accounting for the largest group.
Border Force said criminal gangs “entice victims with promises of free luxury holidays, business-class flights and spending money” before coercing them into carrying cannabis into the UK.
As part of a nationwide awareness campaign at UK airports, Border Force has “advised travellers to refuse offers of free holidays or accommodation, particularly to destinations where cannabis is legal, including Thailand, Canada and parts of the United States.”
The agency also urged travellers to ensure they know the contents of their luggage, avoid carrying bags belonging to others, ignore approaches made through social media platforms, retain control of their passports and personal documents, and remember that bringing cannabis into the UK remains a serious criminal offence regardless of its legal status abroad.
Border Force Lead Officer for Safeguarding, Kate Goldstone, said: “Organised criminal gangs are exploiting young people for profit, living it up while leaving their courier victims facing lifetime 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.”
Also, Border Force warned that anyone caught smuggling cannabis could face arrest, prosecution, a criminal record, up to 14 years’ imprisonment and restrictions on future international travel, with lasting consequences for employment and education.
The agency said cannabis seizures at UK airports have reached record levels, rising by 50 percent over the past year. Seizures from air passengers increased from 2.1 tonnes in 2022 to more than 28 tonnes in 2025.
Although Thailand has emerged as a major source country, Border Force added that “criminal networks also operate in other jurisdictions where cannabis is legal or more readily available, including Canada, the United States and parts of Europe.”
The warning coincides with the implementation of a joint UK-Thailand 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 cannabis or other illegal drugs to report the matter to local authorities, consular services or Crimestoppers.
