Afghanistan, the world's largest producer of opium, has harvested a record crop this year that more than doubled last year's production. Salamt Azimi, the country's minister for counter-narcotics, told VOA's Pashto service that insecurity kept the government from implementing poppy eradication programs, leading to a 64 percent jump in land dedicated to the lucrative crop to 340,000 hectares. The U.N. Office on Drugs and Crime estimated that opium accounted for some 16 percent of the country's Gross Domestic Product last year, including more than two-thirds of the entire agricultural sector. In addition to fueling insecurity, violence and insurgency, the drug production is discouraging private and public investment, a UNODC report said. Afghanistan's opium production plunged in 2001 after the Taliban-led government banned it. But it jumped back to pre-ban levels - and higher - after the U.S. led invasion of the country late that year. U.S. anti-drug officials say the Taliban provides protection to traffickers in exchange for weapons, funding and other support. A single kilogram of heroin can generate approximately $1.5 million by the time it reaches users, and the U.S. is trying to cope with a rise in addiction to opiates, both prescription drugs and illegally produced drugs like heroin. That leads to opportunities to bribe police, judges and customs officials, feeding Afghanistan's endemic corruption and scaring off foreign investment.
