ADVANCE FOR USE TUESDAY, APRIL 8, 2014 AND THEREAFTER - In this Thursday, Feb. 20, 2014 photo, Karen Lewis listens to her son, Cody, a recovering heroin addict, talk abut his life and addiction at the Good Samaritan Methodist Church in Addison, Ill. Though she tried different approaches - punishment, lectures, praise when he entered rehab - nothing stuck. About a month after his release from a court-ordered 8½-month residential treatment program, Cody reverted to his old ways. "I just gave in when I got out," he says. "You can learn every trick in the book to prevent you from using, but you have to use what they teach you." (AP Photo/Charles Rex Arbogast)
