How the Reformulation of OxyContin Ignited the Heroin Epidemic

We gratefully acknowledge helpful comments from seminar participants at the University of Colorado – Denver, University of Connecticut, University of Illinois at Chicago, University of Notre Dame, University of Southern California, University of Melbourne, NBER, Kellogg School of Management, and Southern Methodist University. We are especially grateful for Tom Dailey of Breaking Point Recovery whose guidance and suggestions directed much of our research. Although Tom helped hundreds through the recovery process, he recently lost his life to addiction. He will be missed.
