Border Force has issued a stark warning to UK holidaymakers after 600 people were arrested for cannabis smuggling at UK airports in the first six months of 2026. The number of air passenger couriers caught has surged dramatically, from 142 in 2023 to 976 in 2025, with 2026 on track to exceed that figure.
Criminal gangs are using social media platforms such as TikTok, Snapchat, and Instagram to groom young people into smuggling cannabis into the UK. Men aged 18 to 37 travelling from Thailand make up the largest group of those arrested. The gangs specifically target school and university leavers, first-time travellers, and those tempted by offers of cheap or free holidays from so-called friends.
Five Tips to Avoid Being Recruited
Border Force has shared five tips to help travellers avoid being ensnared by smugglers. First, refuse “free” holidays, flights, or luxury accommodation, particularly to countries where cannabis is legal, such as Thailand, Canada, and parts of the United States. If an offer sounds too good to be true, it probably is.
Second, know what is in your bag. Never travel with a bag that is not yours, and if someone tells you not to look inside your luggage, treat it as a major warning sign. If drugs are found in your bag, even if you did not put them there, you could face arrest, prosecution, and a criminal record.
Third, beware of social media approaches. Criminal gangs use platforms such as TikTok, Snapchat, and Instagram to target young people. Border Force advises resisting these approaches, as they risk a lifetime of painful consequences. Delete and block any such contacts.
Fourth, keep hold of your passport and personal documents at all times. Criminal gangs may ask to take it from you, claiming it is part of a travel arrangement, but it can be a tactic to control and manipulate people, including checking in suitcases in their name. If someone wants to hold onto your passport for you, treat it as a serious red flag.
Fifth, remember that cannabis is not legal to bring into the UK. Criminal gangs may try to convince you that because cannabis is legal where you are travelling, it is acceptable or low risk to bring it back to the UK. It is not. International drug smuggling is a serious criminal offence that can result in imprisonment at home and abroad.
Record Seizures and Joint Crackdown
Border Force’s cannabis seizures are now at a record high, increasing by 50% in the last year. UK law enforcement seized 2.1 tonnes of cannabis from air passengers in 2022, rising to more than 28 tonnes in 2025. While Thailand has been a particular focus, Border Force warns that gangs can operate wherever cannabis is legal or more easily available, including countries such as Canada, the United States, and parts of Europe.
A joint UK-Thailand crackdown on cannabis smuggling has come into force, with Brits caught attempting to smuggle cannabis from Thailand facing average fines of around £17,700 or up to two years in prison. Anyone caught smuggling cannabis could face arrest, prosecution, a criminal record, up to 14 years behind bars, and restrictions on future travel, potentially damaging future employment, education, and life opportunities.
Kate Goldstone, Border Force Lead Officer for Safeguarding, 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.”
Anyone approached about carrying cannabis or other illegal drugs should report it to local authorities, consular services, or Crimestoppers on 0800 555 111.
