UN Estimate of Taliban Opium Revenue
"When the Taliban were in power (in the late 1990s) they extracted US$ 75-100 million a year from taxing opium. In the 2005-2008 period the cumulative revenue from opiate farming and trade accruing to Taliban insurgents is estimated at US$ 350-650 million, or an annual average of US$ 90-160 million in Afghanistan alone. This estimate does not include insurgents’ potential revenues from other drug-related activities (labs, imports of precursors) in Afghanistan and from the US$1 billion opiate trade in Pakistan."
