In the early 20th century, many Olympic athletes began using drugs to improve their athletic abilities. For example, the winner of the marathon at the1904 Games, Thomas Hicks, was given strychnine and brandy by his coach. The only Olympic death linked to doping occurred at the Rome Games of 1960. During the cycling road race,Danish cyclist Knud Enemark Jensen fell from his bicycle and later died. A coroner's inquiry found that he was under the influence of amphetamines. By the mid-1960s, sports federations were starting to ban the use of performance enhancing drugs; in 1967 the IOC followed suit.
The first Olympic athlete to test positive for the use of performance enhancing drugs was Hans-Gunnar Liljenwall, a Swedish pentathlete at the 1968 Summer Olympics, who lost his bronze medal for alcohol use. The most publicized doping-related disqualification was that of Canadian sprinter Ben Johnson, who won the 100 meter dash at the 1988 Seoul Olympics but tested positive for stanozolol. His gold medal was subsequently stripped and awarded to runner-up Carl Lewis, who himself had tested positive for banned substances prior to the Olympics.
In the late 1990s, the IOC took the initiative in a more organized battle against doping, by forming the World Anti-Doping Agency (WADA) in 1999. There was a sharp increase in positive drug tests at the 2000 Summer Olympics and 2002 Winter Olympics. Several medalists in weightlifting and cross-country skiing were disqualified because of doping offenses. During the 2006 Winter Olympics, only one athlete failed a drug test and had a medal revoked.
The IOC-established drug testing regimen (now known as the Olympic Standard) has set the worldwide benchmark that other sporting federations around the world attempt to emulate. During the Beijing games, 3,667 athletes were tested by the IOC under the auspices of the World Anti-Doping Agency. Both urine and blood tests were used to detect banned substances. Several athletes were barred from competition by their National Olympic Committees prior to the Games; only three athletes failed drug tests while in competition in Beijing.Information sourced from Wikipedia.
