Performance-enhancing drugs in other sports

Steroids and other PEDs have been used most prominently by baseball players, but they have also been used by athletes in other sports.

In the NFL, a survey was conducted in 2009 and 1 in 10 players said that they had used anabolic steroids while still playing. 16.3% of offensive lineman and 14.8% of defensive lineman also confidentially admitted doping. Most notably, Shawne Merriman tested positive for steroids a couple of years ago and was suspended for four games.

Doping is also a problem in cycling. Floyd Landis, the winner of the 2006 Tour de France, tested as having a high ratio of testosterone (which is used as a PED) to epitestosterone, another hormone. Later that year, Landis tested positive for a synthetic testosterone. He was then stripped of his Tour de France title and banned from cycling for 2 years. Landis has also accused Lance Armstrong of doping in 2002 and 2003 (two years Armstrong won the Tour de France), probably the most famous cyclist of all-time, of doping. Armstrong has turned aside and denied these claims.

There have also been cases of doping in Olympic sports, most notably with Marion Jones, the famous sprinter. She was accused of and admitting to taking anabolic steroids, and was deeply apologetic to her fans and country. There have also been accusations made of female athletes who either allegedly aren't really female or have abnormally high levels of testosterone and possibly were doping.
