Here Are All The Olympic Athletes Who Lost Medals For Doping Since 1968, And All The Drugs They Took

Fair play and ethical behavior are among the fundamental principles of Olympism laid out in the Olympic Charter. It is these lofty ideals conceived by Pierre de Coubertin that established the Olympics as the world's purest embodiment of sport with the first modern Summer Games in Greece in 1896.

Of course, the Olympics are also about winning medals for those athletes who spend years training for a shot at history. Over the decades, the allure of these precious medals has led many athletes to seek an illicit edge. Since the International Olympic Committee instituted drug testing for the 1968 Winter Olympics in Grenoble, dozens of athletes have been stripped of medals after testing positive for a banned substance. Below is a look back at the recent history of doping in the Olympics.
