Anabolic agents –
Canadian sprinter Ben Johnson was sent home from the 1988 Seoul Olympic Games in disgrace, and stripped of his gold medal after testing positive for drugs. Samples of Johnson's urine were tested for drugs immediately after the 100m final which he won in a world record time of 9.79 seconds. Shortly after Olympic officials confirmed that traces of the anabolic steroid, Stanozol, had been detected. Johnson originally tried to claim that an herbal drink he consumed before the race had been spiked, although the IOC stated that the athlete’s defence will not be accepted. When the urine samples tested positive, Johnson lost his gold medal and world records and admitted he’d been taking drugs since 1981. Johnson was suspended for two years, although returned "clean" to competition in January 1991. His performances were well below his previous standards, but he finally posted a time fast enough to qualify for the 1992 Olympics. Johnson made the semi-final but tripped coming out of the blocks and was eliminated. In February 1993 Johnson again tested positive in a drug test, above the allowed levels of testosterone, and the IAAF banned him from competition for life.

Great Britain’s Terry Newton was a rugby player for Wakefield Trinity Wildcats, and in 2009 he tested positive for the growth hormone drug. Newton opted not to contest the charge brought by the UK Anti-Doping Agency for taking a self-administered human growth hormone. That triggered an automatic two-year ban.
The 31-year-old is the first athlete in the world to test positive for HGH.
"There has been a feeling that you can take growth hormone with impunity but this shows this is no longer the case," said UKAD chief executive Andy Parkinson.
"We have heard from others that growth hormone is being abused by athletes but until now investigations have been of the non-analytical type."
Newton's two-year ban, confirmed by UKAD, was from all codes of rugby and was
