In its final Afghan Opium Survey for 2007 issued today, the United Nations Office on Drugs and Crime (UNODC) shows that opium is now equivalent to more than half (53%) of the country's licit GDP. Speaking at a conference in Brussels on the future of Afghanistan, hosted by Princeton University, the Executive Director of UNODC, Antonio Maria Costa, announced that the total export value of opiates produced in and trafficked from Afghanistan in 2007 is about $4 billion, a 29 per cent increase over 2006.

Approximately one quarter of this amount ($1 billion) is earned by opium farmers. District officials take a percentage through a tax on crops (known as "ushr"). Insurgents and warlords control the business of producing and distributing the drugs. The rest is made by drug traffickers.
