Afghan's Opium is deadliest than their Bullets- UN

A top United Nations official says that the annual number of people killed by Afghan heroin in Western Europe exceeds the total death toll of NATO troops killed in Afghanistan since 2001.

Some 1,800 international coalition troops have been killed in Afghanistan, including 1,100 Americans.

Speaking at an anti-drug conference in Moscow, the head of the U.N. Office on Drugs and Crime, Antonio Maria Costa, said that the world's largest consumer of Afghan drugs is Russia, where more than 70 metric tons of heroin are sold annually.

Russian President Dmitry Medvedev told the conference that heroin is seen as a "serious threat'' to Russian youth.
