== History ==

The use of performance-enhancing tactics or more formally known as PEDs, and more broadly, the use of any external device to nefariously influence the outcome of a sporting event has been a part of the Olympics since its inception in Ancient Greece. One speculation as to why men were required to compete naked was to prevent the use of extra accoutrements and to ep women from competing in events specifically designed for men.<ref name=ancientcheating>{{cite web |url=http://history.howstuffworks.com/ancient-greece/first-olympics3.htm|author=Gibson, Candace|title=How the First Olympics Worked|publisher=Discovery Communications|accessdate=2009-01-05}}</ref> Athletes were also known to drink "magic" potions and eat exotic meats in the hopes of given them an athletic edge on their competition.<ref name=ancientdoping>{{cite web |url=http://news.nationalgeographic.com/news/pf/63532314.html| title=Ancient Olympics mixed Naked Sports, Pagan Partying| publisher=National Geographic Society|accessdate=2009-01-05|first=Stefan|last=Lovgren}}</ref> If they were caught cheating, their likenesses were often engraved into stone and placed in a pathway that led to the Olympic stadium.<ref name=ancientcheating/> In the modern Olympic era, chemically enhancing one's performance has evolved into a sophisticated science, but in the early years of the Modern Olympic movement the use of performance-enhancing drugs was almost as crude as its ancient predecessors.

During the early 20th century, many Olympic athletes discovered ways to practically improve their athletic abilities by having testosterone. For example, the winner of the [[marathon (sports)|marathon]] at the [[1904 Summer Olympics|1904 Games]], [[Thomas Hicks (athlete)|Thomas Hicks]], was given [[strychnine]] and [[brandy]] by his coach, even during the race.<ref>{{cite web|title=Tom Hicks|publisher=Sports-reference.com|url=http://www.sports-reference.com/olympics/athletes/hi/tom-hicks-1.html|accessdate=2008-08-27}}</ref> As these methods became more extreme, it became increasingly evident that the use of [[doping in sport|performance-enhancing drugs]] was not only a threat to the integrity of sport but could also have potentially fatal side effects on the athlete. The only Olympic death linked to athletic drug use occurred at the [[1960 Summer Olympics|Rome Games of 1960]]. During the cycling road race, [[Denmark at the 1960 Summer Olympics|Danish]] cyclist [[Knud Enemark Jensen]] fell from his bicycle and later died. A coroner's inquiry found that he was under the influence of [[amphetamine]], which had caused him to lose consciousness during the race.<ref name=drugdeath>{{cite web |title=A Brief History of Anti-Doping|publisher=World Anti-Doping Agency|url=http://www.wada-ama.org/en/dynamic.ch2?pageCategory.id=312|accessdate=2008-09-10}}</ref> Jensen's death exposed to the world how endemic drug use was among elite athletes.<ref>{{cite book |title=Rome 1960|last=Maraniss|first=David|year=2008|publisher=Simon & Schuster|location=New York|isbn= 1-4165-3407-5|authorlink=David Maraniss}}</ref> By the mid–1960s, sports federations were starting to ban the use of performance-enhancing drugs, and the IOC followed suit in 1967.<ref>{{cite news |first=Sharon|last=Begley|title=The Drug Charade|publisher=Newsweek|date=2008-01-07|url=http://www.newsweek.com/id/86079/output/print|accessdate=2008-08-27}}</ref>

The first Olympic athlete to test positive for the use of performance-enhancing drugs was [[Hans-Gunnar Liljenwall]], a Swedish [[modern pentathlon|pentathlete]] at the [[1968 Summer Olympics]], who lost his bronze medal for alcohol use, 'two beers to steady his nerves'.<ref>{{cite web |title=Hans-Gunnar Liljenwall|publisher=123explore.com |url=http://www.123exp-biographies.com/t/00034345906/|accessdate=2008-08-28}}</ref> Liljenwall was the only athlete to test positive for a banned substance at the 1968 Olympics, as the technology and testing techniques improved, the number of athletes discovered to be chemically enhancing their performance increased as well.

The most systematic case of drug use for athletic achievement is that of the East German Olympic teams of the 1970s and 1980s. In 1990, documents were discovered that showed many [[East Germany|East German]] female athletes, especially swimmers, had been administered [[anabolic steroid]]s and other drugs by their coaches and trainers. Girls as young as eleven were started on the drug regimen without consent from their parents. American female swimmers, including [[Shirley Babashoff]], accused the [[East Germany at the 1976 Summer Olympics|East Germans]] of using performance-enhancing drugs as early as the [[1976 Summer Olympics|1976 Summer Games]].<ref>{{cite news |first=Christine|last=Brennan |title=Babashoff had Mettle to Speak out about Steroids|date=2004-07-14|publisher=USA Today|url=http://www.usatoday.com/sports/columnist/brennan/2004-07-15-brennan_x.htm|accessdate=2008-08-28}}</ref> Babashoff's comments were dismissed by the international and domestic media as sour grapes since Babashoff, a clear favorite to win multiple gold medals, won three silver medals - losing all three times to either of the two East Germans [[Kornelia Ender]] or [[Petra Thümer]], and one gold medal in a relay. There was no suspicion of cheating on the part of the East German female swimmers even though their medal tally increased from four silvers and one bronze in [[Swimming at the 1972 Summer Olympics|1972]] to ten golds (out of a possible 12), six silvers, and one bronze in [[Swimming at the 1976 Summer Olympics|1976]]. No clear evidence was discovered until after the fall of the [[Fall of the Berlin Wall|Berlin Wall]], when the aforementioned documents proved that East Germany had embarked on a state-sponsored drug regimen to dramatically improve their competitiveness at the Olympic Games and other international sporting events. Many of the East German authorities responsible for this program have been subsequently tried and found guilty of various crimes in the German penal system.<ref>{{cite news |first=Jere|last=Longman|title=Just Following Orders, Doctors' Orders|publisher=The New York Times|date=2001-04-22|url=https://query.nytimes.com/gst/fullpage.html?res=9A02E3D71330F931A15757C0A9679C8B63&sec=&spon=&pagewanted=all|accessdate=2008-08-28}}</ref><ref name=DeutscheWelle>{{cite web |title=Sports Doping Statistics Reach Plateau in Germany|publisher=Deutsche Welle|date=2006-02-26|url=http://www.dw-world.de/dw/article/0,2144,786574,00.html|accessdate=2008-08-28}}</ref>

A very publicized steroid-related disqualification at an Olympic Games was the case of [[Canada|Canadian]] sprinter [[Ben Johnson (athlete)|Ben Johnson]], who won the [[Athletics at the 1988 Summer Olympics|Men's 100 metres]] at the [[1988 Summer Olympics|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, but had not been banned due to a lack of consistency in the application of the rules. At that time National Olympic Committees had leeway to determine whether a specific athlete met the criteria to be banned from Olympic competition.<ref>{{cite web |first=Jacquelin|last=Magnay|title=Carl Lewis's positive test covered up|publisher=The Sydney Morning Herald|url=http://www.smh.com.au/articles/2003/04/17/1050172709693.html|date=2003-04-18|accessdate=2008-08-28}}</ref>

==Response==

In the late 1990s, the IOC took the initiative in a more organized battle against doping, leading to the formation of the [[World Anti-Doping Agency]] (WADA) in 1999. The [[2000 Summer Olympics]] and [[2002 Winter Olympics]] have shown that the effort to eliminate performance-enhancing drugs from the Olympics is not over, as several medalists in weightlifting and cross-country skiing were disqualified due to failing a drug test. 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 attempt to emulate.<ref>{{cite news |first=Zachary|last=Coile|title=Bill Seeks to Toughen Drug Testing in Pro Sports|date=2005-04-27|newspaper=San Francisco Chronicle|url=http://www.sfgate.com/cgi-bin/article.cgi?file=/c/a/2005/04/27/MNGMICG0SS1.DTL|accessdate=2008-09-03}}</ref> During the [[2008 Summer Olympics|Beijing games]], 3,667 athletes were tested by the IOC under the auspices of the World Anti-Doping Agency.

While several athletes were barred from competition by their National Olympic Committees prior to the Games, six athletes failed drug tests while in competition in Beijing.<ref>{{cite web |title=Doping: 3667 athletes tested, IOC seeks action against Halkia's coach|date=2008-08-19|publisher=Express India Newspapers|url=http://www.expressindia.com/latest-news/Doping-3667-athletes-tested-IOC-seeks-action-against-Halkias-coach/350677/|accessdate=2008-08-28}}</ref><ref name=WADAHistory>{{cite web|title=A Brief History of Anti-Doping|publisher=World Anti-Doping Agency |url=http://www.wada-ama.org/en/dynamic.ch2?pageCategory.id=312|accessdate=2008-08-28}}</ref>

What follows is a list of all the athletes that have tested positive for a banned substance either during or after an Olympic Games in which they competed. Any medals listed were revoked by the [[International Olympic Commission]] (IOC). In 1967 the IOC banned the use of performance-enhancing drugs, instituted a Medical Commission, and created a list of banned substances.<ref name="Mottram2011">{{cite book|first=David R.|last=Mottram|title=Drugs in Sport|url=https://books.google.com/books?id=c2e4IUmuvrEC&pg=PA21|accessdate=19 July 2012|date=30 March 2011|publisher=Taylor & Francis|isbn=978-0-415-55086-4|pages=21–}}</ref> Mandatory testing began at the following year's Games.<ref name="Mottram2011"/>

===1980 Moscow===

{{main article|1980 Summer Olympics}}

Though no athletes were caught doping at the 1980 Summer Olympics, it has been claimed that athletes had begun using [[testosterone (medication)|testosterone]] and other drugs for which tests had not been yet developed. A 1989 report by a committee of the [[Australian Senate]] claimed that "there is hardly a medal winner at the Moscow Games, certainly not a gold medal winner...who is not on one sort of drug or another: usually several kinds. The Moscow Games might well have been called the Chemists' Games".<ref name="Hunt2007"/>

A member of the IOC Medical Commission, Manfred Donike, privately ran additional tests with a new technique for identifying abnormal levels of testosterone by measuring its ratio to [[epitestosterone]] in [[urine]]. Twenty percent of the specimens he tested, including those from sixteen gold medalists would have resulted in disciplinary proceedings had the tests been official.<ref name="Hunt2007"/> The results of Donike's unofficial tests later convinced the IOC to add his new technique to their testing protocols.<ref name="D.

A WADA report released in 2015 detailed an extensive [[Doping in Russia|Russian state-sponsored doping]] program implicating athletes, coaches, various Russian institutions, doctors and labs. The report stated that the London Olympic Games "were, in a sense, sabotaged by the admission of athletes who should have not been competing" and detailed incidents of bribery and bogus urine samples. The report recommended that Russia be barred from track and field events for the 2016 Olympics. It also recommended lifetime bans for five coaches and five athletes from the country, including runners [[Mariya Savinova]], [[Ekaterina Poistogova]], Anastasiya Bazdyreva, Kristina Ugarova, and Tatjana Myazina.<ref>{{cite news|last1=Ruiz|first1=Rebecca R.|title=Drugs Pervade Sport in Russia, World Anti-Doping Agency Report Finds|url=https://www.nytimes.com/2015/11/10/sports/russian-athletes-part-of-state-sponsored-doping-program-report-finds.html|work=The New York Times|date=November 9, 2015}}</ref><ref>{{cite web|title=The Independent Commission Report #1|url=https://wada-main-prod.s3.amazonaws.com/resources/files/wada_independent_commission_report_1_en.pdf|publisher=Independent Commission Investigation|date=November 9, 2015}}</ref>

On 15 June 2016, it was announced that four London 2012 Olympic weightlifting champions had tested positive for performance-enhancing drugs.
