 Afghanistan is the world's largest opium grower, according to the UN, having produced an estimated 2,000 tons in 1992.This is a concern not only for the West, where the production fuels the illegal heroin trade, but also at home, where it is estimated that 15% of all adult Afghan males age 15-40 are addicted to hard drugs.After Hekmatyar's forces captured Defense Minister Masood's ministry building in Kabul, which they were shelling for a year, a peace accord is signed.
