Kabul , Afghanistan ( CNN ) -- Troops with the NATO-led force in Afghanistan have seized more than 6,000 pounds of illegal drugs , the force said . Troops found more than 5,300 pounds of processed opium , more than 1,000 pounds of wet opium paste , approximately 50 pounds of heroin , and multiple firearms with ammunition were found in the truck , the NATO-led International Security Assistance Force said . Authorities arrested two people and destroyed most of the drugs , though they kept some narcotics to analyze . The confiscation took place Wednesday in southern Afghanistan -- in the Maiwand district of Kandahar province -- after troops stopped a `` suspicious '' truck . Afghan opium kills 100,000 people a year worldwide -- more than any other drug -- and the opiate heroin kills five times as many people in NATO countries each year than the total number of NATO troops killed in combat in Afghanistan , a recent U.N. report said . About 15 million people around the world use heroin , opium or morphine , fueling a $ 65 billion market for the drug and also fueling terrorism and insurgencies . The Taliban raised $ 450 million to $ 600 million over the past four years by `` taxing '' opium farmers and traffickers , Antonio Maria Costa , head of the U.N. Office on Drugs and Crime , said in a report last autumn . Not all the money is going into the pockets of rebels or drug dealers , though . Some Afghan officials are making money off the trade as well , he said .
