Marion Jones admitted to using steroids as she prepared for the 2000 Summer Games in Sydney, Australia. She became the first woman to win five medals at one Olympics but was stripped of those medals in 2007.
Jones admitted to taking the banned substance tetrahydrogestrinone, a powerful anabolic steroid also known as THG or "the clear." In 2007, after initially denying claims, she said she took the drug from 1999 until 2001, including during her competition at the Olympic games. In 2003, Jones had lied to federal agents about her use of the drug. She told officials that her coach, Trevor Graham, first gave her steroids after he claimed it was flaxseed oil.
As a result of her confession, Jones served six months in federal prison for lying to federal prosecutors, and she received two years' probation as well as community service.
