the line first, with Lewis second, Linford Christie of Great Britain third, and Smith fourth. When Johnson tested positive for anabolic steroids and was stripped of his title, Smith was upgraded to third position. Johnson was not the only participant whose success was questioned: Lewis had tested positive at the Olympic Trials for pseudoephedrine, ephedrine and phenylpropanolamine. 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). 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. 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. 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." Christie was found to have metabolites of pseudoephedrine in his urine after a 200m heat at the same Olympics, but was later cleared of any wrongdoing. Of the finalists, only sixth Robson da Silva and former 100 meter world record holder and eventual Olympic third over the distance, Calvin Smith never failed a drug test during their career. Smith later said: "I should have been the gold medalist." Personal life Smith is married to Melanie, whom he met at college, and has two children, a daughter Brittney and a son Calvin Smith Jr. Smith retired from athletics in 1996 and was then for two years an assistant coach at the University of Alabama. He then moved with his family to Tampa, Florida where he has pursued a variety of careers. He is currently working for a non-profit agency
