In November 1942, the Italian cyclist Fausto Coppi took "seven packets of amphetamine" to beat the world hour record on the track.  In 1960, the Danish rider Knud Enemark Jensen collapsed during the 100 km team time trial at the Olympic Games in Rome and died later in hospital. The autopsy showed he had taken amphetamine and another drug, Ronicol , which dilates the blood vessels. The chairman of the Dutch cycling federation, Piet van Dijk, said of Rome that "dope – whole cartloads – [were] used in such royal quantities." 
But Götz had no regrets and went on to win the UEFA Cup in 1988 with his new West German team, Bayer Leverkusen. But life in the West did not mean he, or others, had escaped the clutches of the Stasi (indeed, he later found out that the Stasi had, within their files, photographs of his new home in West Germany). Cases of defectors drugged and smuggled back East, although rare, were not unheard of. A friend of Götz in West Germany, a fellow East German, was killed in a car accident. Götz, suspecting it was no accident, feared for his own life.
5. Baseball (positive test results: percent) : Olympic baseball is certainly not at the center of the sport, especially since it was discontinued as an Olympic event after the 2008 Games. Still, baseball yielded one of the highest percentages of positive test results in the years before it was eliminated. And steroid use in Major League Baseball was almost certainly worse than in the Olympics (the MLB did not even have steroid testing with penalties until 2004 ). The tests have been strengthened since then, and the situation appears to be improving relative to the dark days of the 1990s and early 2000s. Just as the sport seemed to be turning the corner, however, it came to light in June that the league was seeking to suspend about 20 players, including stars Alex Rodriguez and Ryan Braun, for alleged involvement in a steroid ring.
