David Johnston is a retired board-certified emergency room doctor from Minnesota with more than 30 years of experience treating patients with a wide range of prescription drugs. While this interview was originally recorded back in April 2011, Dr. Johnston's no-nonsense approach to the use of all prescription drugs and drug safety are as relevant today as they were five years ago. And while the focus of the interview was not prescription opiate abuse, his core messages regarding America's deepening love affair with drugs applies nevertheless.
