Самое крутое соревнование в прыжках в истории спорта: Майк Пауэлл vs Карл Льюис, Токио-1991. Полное видео.

In 2003, Wade Exum, the United States Olympic Committee's director of drug control administration from 1991 to 2000, gave copies of documents to Sports Illustrated that revealed that some 100 American athletes failed drug tests from 1988 to 2000, arguing that they should have been prevented from competing in the Olympics but were nevertheless cleared to compete. Before showing the documents to Sports Illustrated, Exum tried to use them in a lawsuit against USOC, accusing the organization of racial discrimination and wrongful termination against him and cover-up over the failed tests. His case was summarily dismissed by the Denver federal Court for lack of evidence. The USOC claimed his case "baseless" as he himself was the one in charge of screening the anti-doping test program of the organization and clarifying that the athletes were cleared according to the rules.[83][84]

Lewis was among the named athletes. Exum's documents revealed that he had tested positive three times at the 1988 Olympics trials for minimum amounts of pseudoephedrine, ephedrine, and phenylpropanolamine, which were banned stimulants. Bronchodilators was also found in cold medication. Due to the rules, his case could have led to disqualification from the Seoul Olympics and suspension from competition for six months. The levels of the combined stimulants registered in the separate tests were 2 ppm, 4 ppm and 6 ppm.[83]

Lewis defended himself, claiming that he had accidentally consumed the banned substances. After the supplements that he had taken were analyzed to prove his claims, the USOC accepted his claim of inadvertent use, since a dietary supplement he ingested was found to contain "Ma huang", the Chinese name for Ephedra (ephedrine is known to help weight loss).[83] Fellow Santa Monica Track Club teammates Joe DeLoach and Floyd Heard were also found to have the same banned stimulants in their systems, and were cleared to compete for the same reason.[85][86]

The highest level of the stimulants Lewis recorded was 6 ppm, which was regarded as a positive test in 1988 but is now regarded as negative test. The acceptable level has been raised to ten parts per million for ephedrine and twenty-five parts per million for other substances.[83][87] According to the IOC rules at the time, positive tests with levels lower than 10 ppm were cause of further investigation but not immediate ban. Neal Benowitz, a professor of medicine at UC San Francisco who is an expert on ephedrine and other stimulants, agreed that "These [levels] are what you'd see from someone taking cold or allergy medicines and are unlikely to have any effect on performance."[83]

Following Exum's revelations the IAAF acknowledged that at the 1988 Olympic Trials the USOC indeed followed the correct procedures in dealing with eight positive findings for ephedrine and ephedrine-related compounds in low concentration. The federation also reviewed in 1988 the relevant documents with the athletes' names undisclosed and stated that "the medical committee felt satisfied, however, on the basis of the information received that the cases had been properly concluded by the USOC as 'negative cases' in accordance with the rules and regulations in place at the time and no further action was taken".[88][89]

"Carl did nothing wrong. There was never intent. He was never told 'you violated the rules'" said Martin D. Singer, Lewis's lawyer, who also said that Lewis had inadvertently taken the banned stimulants in an over-the-counter herbal remedy.[90] In an interview dating back April 2003 Carl Lewis agreed that he tested positive three times in 1988 but he was let off as that was the normal practice in those times.[91] "The only thing I can say is I think it's unfortunate what Wade Exum is trying to do," said Lewis. "I don't know what people are trying to make out of nothing because everyone was treated the same, so what are we talking about? I don't get it."
