...it is evident from the start of opium production around Diwaniya that some gangs think there is money to be made by following the example of Afghanistan. Given that they can guarantee much higher profits from growing opium poppies than can be made from rice, many impoverished Iraqi farmers are likely to cultivate the new crop.

The growing and smuggling of opium will be difficult to stop in Iraq because much of the country is controlled by criminalised militias. American successes in Iraq over the past year have been largely through encouraging the development of a 70,000-strong Sunni Arab militia, many of whose members are former insurgents linked to protection rackets, kidnapping and crime. Muqtada al-Sadr, the leader of the powerful Shia militia, the Mehdi Army, says that criminals have infiltrated its ranks.

The move of local warlords, both Sunni and Shia, into opium farming is a menacing development in Iraq, where local political leaders are often allied to gangsters. The theft of fuel, smuggling and control of government facilities such as ports means that gangs are often very rich. It is they, rather than impoverished farmers, who have taken the lead in financing and organising opium production in Iraq.
