world's largest producer of opium; poppy cultivation decreased 22% to 157,000 hectares in 2008 but remains at a historically high level; less favorable growing conditions in 2008 reduced potential opium production to 5,500 metric tons, down 31 percent from 2007; if the entire opium crop were processed, 648 metric tons of pure heroin potentially could be produced; the Taliban and other antigovernment groups participate in and profit from the opiate trade, which is a key source of revenue for the Taliban inside Afghanistan; widespread corruption and instability impede counterdrug efforts; most of the heroin consumed in Europe and Eurasia is derived from Afghan opium; vulnerable to drug money laundering through informal financial networks; regional source of hashish (2008)
