Holed up alone in a suburban British house thousands of miles from home, cannabis farmer Cuong Nguyen, one of thousands of Vietnamese migrants working in the UK’s multi-billion dollar weed industry, spent months carefully nurturing his plants.
Cuong – who is now 41 – slipped into the United Kingdom illegally, hidden under a lorry, before going on to grow cannabis in homes, hotels and even a stable.
His dangerous journey from the poor, rough Vietnamese port town of Haiphong to Britain’s illegal cannabis farms was driven by big dreams.
“All I ever wanted was to make money … whether it was legal or illegal,” Cuong, who is now back in Vietnam, told AFP.
It was criminal career steered by the Vietnamese gangsters behind the UK’s huge marijuana trade, which researchers value at around 2.6bn pounds (US$3.2bn) a year.
Cuong claims he went to the UK willingly, looking for ready cash in a country with some of the highest prices for cannabis anywhere in Europe.
But many others, including children, are tricked and trafficked into working for the shadowy Vietnamese drug bosses who have become the unlikely kingpins of the UK weed trade.
The story of the self-professed hustler and low-level crook offers a unique insight into the routes taken by some Vietnamese migrants.
But it also turns a spotlight on life on the margins in Vietnam, where criminal gangs trade on poverty and a lack of opportunity to find new recruits.
Cuong, a former small-time crook and drug user, was 29 when he set off for the UK.
It was 2008 and the cannabis trade promised riches, he says, so he paid $15,000 to brokers for a fraudulent passport and a spot on a tour group to Europe.
He slipped away from the tour in France and joined a well-worn migrant route to a camp in Calais where Vietnamese people smugglers arranged for him to cross the channel to Britain – under the belly of a lorry.
“If you fall you’re dead,” explains Cuong, who made the overnight journey to Dover with three other Vietnamese migrants.
Arriving in a new country and speaking no English, his options were limited, so Cuong again turned to the migrant network for help.
He ended up in Bristol and worked for a man running several cannabis farms in suburban homes.
Cuong says he had to work on his own, confined to the house and reliant on weekly food drops by his handlers.
“I got up early, ate rice and prepared feed for my plants… put them under lights for two hours and watered them,” recalls Cuong, his mundane routine punctuated by fear of arrest.
It was a common set-up: houses rented or bought in inconspicuous suburbs and converted into drug operations.
Police have also busted cannabis farms in dog kennels, pubs, an abandoned hospital and even a former nuclear bunker – many of them run by Vietnamese.
Around 12 percent of all cannabis convicts in the country are Southeast Asian, more than any other non-European nationality, according to the National Police Chiefs’ Council.
It took six months for the police to show up in Cuong’s neighbourhood.
Panicked, he bundled up as many plants as he could in bin bags and made a run for it. But it was not long before he was back in business, growing weed in a hotel near Bristol.
He had earned nearly $19,000 – a small fortune compared with salaries back home – but accuses his boss of cheating him out of thousands more.
Most migrants from Vietnam come from poor central provinces. Many head to the UK, sending cash home which is spent on new cars, motorbikes and home renovations.
But the journey is not cheap.
Smugglers charge up to $40,000 for travel documents and a plane ticket, usually to eastern Europe where the overland trip to the UK begins.
Some fall prey to traffickers; by the time they make it across the English Channel they are thousands of dollars in debt and forced to work in brothels, nail bars or cannabis farms.
More than 3,100 Vietnamese adults and children were identified as potential trafficking victims by the UK government between 2009 and 2018, according to a report by Anti-Slavery International, ECPAT UK and Pacific Links Foundation.
Cuong eventually headed to London, where he drifted for several years, selling drugs and training new cannabis farmers.
But in 2014 he was arrested for smoking cannabis. His fingerprints tied him to the Bristol grow house.
Crown Court records show he was convicted for growing cannabis and sentenced to 10 months’ jail. Eventually, he was deported.
He joined more than 1,600 returnees to Vietnam either by choice or by force since 2014, including at least 22 who were under the age of 14, according to Home Office data.
Hundreds of other children have been identified as potential trafficking victims by the Home Office.
Some are back in Vietnam in debt and at serious risk of being retrafficked in what amounts to a “merry-go-round” of crime and poverty, according to independent trafficking expert Mimi Vu.
Adjusting to life in Vietnam has been tough for Cuong, who returned broke and now lives in a bare house in Haiphong.
But he says he is reformed and hopes to open a salon to help provide for the baby he is expecting with his new girlfriend.
“In the past I had to be tough and aggressive,” he says. “Now I have to be soft and nice.”
