TEHRAN, IRAN -- JUNE 26: An Iranian soldier watches over 50 tons of narcotics, mostly heroin, due to be burned after seizure during anti-drug operations to stop smugglers crossing from Afghanistan to Iran, on June 26, 2005 in Tehran, Iran. Since the fall of the Taliban in late 2001 to American forces, Afghanistan has again surged to become one of the world's top producers of narcotics. The drugs were destroyed to mark the International Day Against Drug Abuse and Illicit Trafficking. (Photo by Scott Peterson/ Getty Images)
