This week Reactions explains how chemistry is used to find which Olympic teams are doping. Science plays a huge role on both sides of the performance-enhancing drug battle. On one side are officials and scientists, aiming to keep the competitions fair; on the other are underground or overseas chemists, creating new drugs to cheat the system.
