Illicit drugs:
world's largest producer of opium; poppy cultivation increased 7 percent, to a record 211,000 hectares in 2014 from 198,000 hectares in 2013 while eradication dropped sharply; relatively low opium yields due to poor weather kept potential opium production—6,300 metric tons—below the record set in 2007; 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; Afghanistan is also struggling to respond to a burgeoning domestic opiate addiction problem; vulnerable to drug money laundering through informal financial networks; illicit cultivation of cannabis and regional source of hashish
