In this Friday, March 21, 2014 photo, Cody Lewis, right, jokes with his sister, Mackenzie, as she surfs the Internet at their suburban Chicago home in Aurora, Ill. Lewis was consumed by heroin. Every day was the same: Get up sick if he hadn't used in 12 hours. Figure out how to get money. Then drive 35 miles from his suburban home to Chicago to score. "My whole existence," he says, "was just finding ways to get high." (AP Photo/Charles Rex Arbogast)
