Vivitrol

Philip Kirby says he first used heroin during a stint in a halfway house a few years ago, when he was 21 years old. He quickly formed a habit.

"You can't really dabble in it," he says.

Late last year, Kirby was driving with drugs and a syringe in his car when he got pulled over. He went to jail for a few months on a separate charge before entering a drug court program in Hamilton County, Ind., north of Indianapolis. But before Kirby started, he says the court pressured him to get a shot of a drug called Vivitrol.
