A drug addict smokes heroin under a bridge in Peshawar, Pakistan, on April 22, 2006. Peshawar, located near the Afghan border, has the cheapest heroin in the world, outside of Afghanistan, where more than 90 percent of it is produced. Impoverished addicts from across Pakistan often move to Peshawar because of the cheap price and high quality of the drug.
