The United Arab Emirates has figured out how to win the drug war:
A father-of-three who was found with a microscopic speck of cannabis stuck to the bottom of one of his shoes has been sentenced to four years in a Dubai prison.
Keith Brown, a council youth development officer, was travelling through the United Arab Emirates on his way back to England when he was stopped as he walked through Dubai's main airport.
A search by customs officials uncovered a speck of cannabis weighing just 0.003g—so small it would be invisible to the naked eye and weighing less than a grain of sugar—on the tread of one of his shoes.
One man has even been jailed for possession of three poppy seeds left over from a bread roll he ate at Heathrow Airport. Painkiller codeine is also banned.
If suspicious of a traveller, customs officials can use high-tech equipment to uncover even the slightest trace of drugs.
Mr Brown was detained and arrested in September last year and has been held in a cell with three other men in the city prison ever since.
This week the youth worker, who has two young children and a partner at home in Smethwick, West Midlands, was sentenced to four years in prison.
A 25-year-old Briton who was found with a similar speck in one pocket as he arrived on holiday has been awaiting sentence since November.
Meanwhile a Big Brother TV executive has so far been held without charge for five days after being arrested for possessing the health supplement melatonin.
The authorities claim to have discovered 0.01g of hashish in his luggage.
