In an example of how large the drug trade is in Afghanistan, NATO forces recently found 260 tons of hashish.

From the AP (via IHT):

Afghan counternarcotics officials said Wednesday that they uncovered 260 tons of hashish hidden in 6-foot-deep trenches in southern Afghanistan in what one DEA official said appears to be the world’s biggest drug bust.

The hashish, found in the southern province of Kandahar on Monday, was worth more than $400 million and would have netted the Taliban about $14 million in profits, NATO’s International Security Assistance Force said.

The hashish weighed as much as 30 double-decker London buses, ISAF said. The drugs were burned on site. Hashish is a concentrated form of marijuana.
