Opium production in Afghanistan reached record levels last year, the United States has said. The US State Department's annual report on narcotics also said the flourishing drugs trade was undermining the fight against the Taleban. Poppy production rose 25% in 2006, a figure US Assistant Secretary of State Ann Patterson described as alarming. Four years after the US and its British allies began combating poppy production, Afghanistan still accounts for 90% of the world's opium trade.
