The history of athletes caught doping at the Olympics dates back to 1968 when Swedish pentathlete, Hans-Gunnar Liljenwall lost a bronze medal for alcohol use.
Lijenwall was found to have had Ethanol in his system. Now that's fuelling.
Times have changed, and not for the better.
Today we look at the most infamous cases of doping at the Olympics, and in a few instances we have only found out about these cheaters years after the fact.
The total number of athletes caught cheating at the Olympic games has tripled since 1988 - will Rio see that number drop? Only time will tell.
Ben Johnson
Johnson lost to Carl Lewis in the 1984 Los Angeles games, and during the build-up to Seoul the Canadian promised he would be more prepared.
Clearly he was.
In 1988 Johnson was found to have a PED (Performance Enhancing Drug) in his system after winning the 100m final.
The American media's cries of injustice after cheating their hero Lewis out of his Olympic moment led to a new level of public awareness - and skepticism - of doping in sport.
Lance Armstrong
The world's best known cyclist won a bronze medal in the time trial at the Sydney Olympics.
It would be 12 years before the medal was stripped from the American after a 2012 investigation concluded that Armstrong was heavily involved in doping, trafficking and covering up drug use throughout his career.
How many other tainted medals from that period are still to be uncovered?
Tyler Hamilton
Long-time teammate of Armstrong, Hamilton fully admitted to doping at the Athens Olympics where he won gold in the time trial.
The American handed his medal back years later after being the initial whistle blower in the downfall of Armstrong.
Marion Jones
Jones competed at both the Sydney and Athens Olympics and was widely regarded as one of the best athletes on the planet during a five year period where she dominated track and field.
Jones won five medals in Sydney including three sprint golds and was the world record holder in the women's 100m.
Consistently proclaiming her detest for drug cheats, Jones was a key player in the BALCO doping scandal in the early 2000's.
In October 2007 Jones admitted to lying under oath and to her heavy use of steroids prior to the 2000 games.
She was subsequently stripped of her medals.
Nadzeya Ostapchuck
How could we not put the Belarusian on the list?
Probably the most famous drug cheat in New Zealand sporting history, Ostapchuck 'beat' Valerie Adams to shot put gold in London four years ago.
But just 48 hours later we learned that she had failed a post competition drugs test, and our Val was rightfully awarded her second consecutive Olympic gold medal.
