The Doping Arms Race: Performance-enhancing drugs in sports and the challenges of detection

— If it were possible for you to take a pill that would turn you into an Olympic champion but would kill you soon after, would you take it? This question may seem absurd to many people, but when elite athletes were asked a similar question, about 50% responded “yes.” Doping, or the use of banned performance-enhancing drugs, originated in ancient times, but the use of these substances has increased in recent decades [3]. Each year, more athletes are added to the list of those disgraced, imprisoned, and even killed due to the use of performance-enhancing drugs. Recently, the world-renowned cyclist Lance Armstrong added his name to the list, after more than a decade of denying allegations of doping.
