Residents wait for food to be distributed as one of them plays a religious song on the guitar at "The Light of The World" rehabilitation centre for heroin addicts in Myitkyina, the capital of Myanmar's Kachin state July 6, 2013. The centre, run by The Kachin Baptist Convention offers a 3-month "course" of prayer, Bible study and devotional singing for drug users. There is no methadone at the centre. Myanmar is the world's largest producer of opium after Afghanistan, and use of its derivative heroin is widespread. The centre's popularity is a testament both to the severity of Myanmar's drug problem and the lack of options for users in a poor country where modern treatment programmes are rare.

Drug addicts visit the Nejat drug rehabilitation centre, an organisation funded by the United Nations providing harm reduction and HIV/AIDS awareness, in Kabul January 29, 2012. With little funding and no access to substitution drugs such as methadone, treatment is rudimentary at Nejat for a problem that is growing in a dirt-poor country riven by conflicts for more than three decades. Opiate consumption in Afghanistan, where it has long been a medication but in recent years has been used increasingly for recreation, is also on a sharp rise. Nejat estimates around 60,000 women in Afghanistan regularly take illegal drugs, including hashish and marijuana.
