Wun Naung Lay looks through the doors of a bamboo cell called the "Special Prayer Room", where he is locked in for his first week at the Youth for Christ Centre for heroin addicts, near Naung Chein in Myanmar's Kachin state July 5, 2013. Naung Lay is one of more than 600 young men who have undergone primitive drug rehabilitation at the Youth for Christ Centre, a collection of tin-roofed shacks on a riverbank in Kachin State. Myanmar is the world's second-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.
