Ruhollah, 25, an Afghan refugee returnee from Iran, smokes heroin at the former Russian Cultural Center, Kabul, Afghanistan, Apr. 9, 2009. In addition to the 650 drug addicts who reside at the cultural center, an estimated 1500 more people go there to buy and use drugs. The United Nations Office on Drugs and Crime emergency detox center began operating at the end of January 2009 to stem the daily deaths occurring among the drug-addicted population living on the sprawling cultural center grounds. The detox center is the largest ad-hoc drug treatment center in Afghanistan, serving 650 residents with a daily hot meal, detoxification assistance, medical aid and counseling.
