Olympians have been twisting the guidelines in an attempt to give themselves an advantage over the competitors since the games commenced. In spite of this, the International Olympic Committee (IOC) only began testing for performance-enhancing substances in 1968, and only seem to have really begun taking the situation critically in the 1990s.
As for the 1968 Games, regardless of that, a large percentage of Olympians are believed to have been using performance-enhancing drugs, they only were able to catch and disqualify one guy Hans-Gunnar Liljenwall a Swedish modern pentathlete. What harmful chemical did he take to get him self-disqualified?
He drank two beers just before an event, causing in him becoming the first person to be disqualified for “doping”.
