More than 200 British nationals are currently detained overseas in drug-smuggling cases involving cannabis originating from Thailand, Foreign Office figures show.
The UK government said consular cases involving Britons arrested abroad for drug smuggling more than quadrupled between 2023 and 2025, rising from just over 80 to more than 340. There have already been more than 160 new cases in 2026.
The majority of arrests have been in Southeast Asia, including Thailand, Malaysia, Cambodia and Laos. Around 60 per cent of those affected since 2024 are aged between 16 and 30.
For British visitors and residents in Thailand, the warning is straightforward: do not carry luggage, parcels or goods for anyone else, even if they appear to contain ordinary items or are offered as part of a free trip. Bags may also be checked again while transiting through another country.
Free holidays and easy money promises
The Foreign, Commonwealth & Development Office said recruits are commonly approached through social media with promises of free holidays, quick cash and supposedly low-risk work.
They may be told cases contain clothes, gold or cash, while suitcases in fact hold cannabis. The government said organised gangs profit while those recruited face potentially severe sentences abroad.
Minister for Consular and Crisis Stephen Doughty MP said: "Far too many British nationals are being lured into drug smuggling schemes by criminal gangs that promise free travel or a quick way to make cash.
"The reality is very different, and detainees are warning about the dire living conditions they now face decades of in prison or, in some countries, the possibility of the death penalty."

A third of young travellers surveyed for the Foreign Office did not see travelling with luggage packed by another person as risky. Thirty per cent said they would consider taking an item abroad despite being unsure whether it was allowed.
One Briton detained on cannabis offences said: "At the end of the day, it's your freedom you're risking, and once it's gone, it's not easy to get back."
Severe penalties and lengthy detention
Penalties can include decades in prison, life sentences, whipping and, in some countries, the death penalty. Malaysia can impose life imprisonment and a minimum of 15 strokes of whipping for trafficking, while Cambodia can sentence offenders to up to 30 years.
Legal proceedings can take months to reach court, and the Foreign Office warned that prison conditions may be harsh, healthcare access limited and that British nationals have previously died in custody in Southeast Asia.
The cases include Bella Culley, from Billingham, who was arrested at Tbilisi airport in May last year after travelling from Thailand. A Georgian court found her guilty over 12kg of marijuana and 2kg of hashish, sentencing her to five months and 25 days - time already served - after her family paid a GBP137,000 fine under a plea deal.
Taylor Johnson, 20, from Wednesbury, was sentenced in July to nine years and two months in Turkey after a sniffer dog found GBP300,000 of cannabis in a suitcase following his flight from Thailand. His girlfriend, Holly Cooper, was acquitted after no drugs were found in her bag.
