During the 1990s, opium, and by extension, heroin, became the chief source of income for Afghanistan, growing more than 70 percent of the world's supply. In 2000, the ruling Taliban banned poppy growth and production fell to almost nothing. Since the US-led war against the Taliban, however, farmers quickly began replanting the opium-bearing flowers.
