Not depressed yet? You soon will be. Iraq is already a drugs transit route, but now it's becoming a heroin producer.
I'd cry, but in fact things are already so bad it's hard to see how this makes anything in Iraq that much worse. The Iraqi insurgents do not seem to be constrained by money in any obvious way - after all, there's that other addictive substance whose production is often associated with violence and criminality that Iraq exports. And, given the agricultural problems referred to, it's not as if it's going to be a second Afghanistan in terms of production.
But it probably will mean more turf wars and blood feuds, not to mention more heroin addicts and more AIDS cases. Purple fingers.
