Washington: Newly-obtained data shows that the US Army has investigated 56 soldiers in Afghanistan over the last two years on suspicion of using or distributing heroin, morphine or other drugs.
During that time, eight soldiers died of drug overdoses.
While the cases represent just a slice of possible drug abuse by US troops in Afghanistan, they provide a sombre snapshot of the illicit trade in the war zone.
Activities include young Afghans peddling heroin, soldiers dying after mixing cocktails of opiates, troops stealing from medical bags and Afghan soldiers and police dealing drugs to their US comrades.
US Army officials say that while the presence of such readily available opium is a concern, opiate abuse has not been a pervasive problem for troops in Afghanistan.
