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.
