DUSHANBE, January 26, 2013, Asia-Plus – According to Global Post, the Wall Street Journal reported on January 25 that the United States military has blacklisted Afghanistan''s leading private airline for allegedly ferrying large quantities of opium on civilian flights.

Military officials interviewed by the WSJ have said that Kam Air smuggles the drug to Tajikistan, where it is distributed to the rest of the world.

Kam Air, the WSJ said, denies the charges. It''s not clear how much business the airline may lose as a result of the blacklisting; Kam Air is the first major Afghan company to be penalized by the US military over drug allegations, the WSJ said.

"Kam Air is too large of a company not to know what has been going on within its organization," a US Army commander said to the WSJ.

Afghanistan is the world''s largest producer of opium — its farms supply about 80 percent of the world''s supply, The New York Times reported.

A United Nations report in November found that while opium harvesting was down by a third in Afghanistan, cultivation of poppies was up 18 percent. According to UN officials, as long as Afghan farmers are committed to growing poppies, Afghanistan will remain a major producer of opium and heroin.

The Afghanistan government has been ambivalent about cutting down on the opium trade.

Meanwhile, the Taliban and other militant groups often tax poppies in the areas under their control.  According to The New York Times, the Taliban probably made at least $155 million from poppies in 2012.

Tajikistan''s government also declined to comment on the allegation, according to the WSJ. Tajikistan is the poorest former Soviet country, and according to the WSJ, it''s likely to become a major trafficking route for Afghan opium to reach the rest of the world. Many drug smugglers there enjoy high-level government protection.

The U.N. estimates that Afghan opiates kill 10,000 people a year in the U.S. and other NATO countries, compared with some 400 coalition soldiers killed last year by the Taliban.

Kam Air operates a fleet of some 16 planes, including Boeing 767 and 747 aircraft and Antonov cargo planes. The task force believes that domestic passenger routes have been used to ferry opium around the country, according to a U.S. official in Kabul.  But the investigation is focused on Central Asia, the official said. “Kam Air is flying out bulk quantities of opium,” the official said.
