Răducan competed at the 2000 Sydney Olympics, where she contributed strongly to the Romanian team's gold medal and won an individual silver medal on the vault. She was also the original winner of the all-around title, but was disqualified and stripped of her gold medal shortly after the competition concluded, when it was revealed that she had failed doping controls, testing positive for pseudoephedrine, a banned substance. She and her coaches maintained that she had been given the substance in two cold medicine pills by a Romanian team physician, and that they had not affected her performance in any way.
