I know that the '72 Olympics was the first Games to have formal testing (I'm thinking there may have been some "informational sampling" done at Mexico in '68), although in a quick check of the Olympic Edition of
T&FN for Munich, we apparently didn't even deem it an important enough subject to mention (!).
We (Bob Hersh) did write this in the OT coverage a couple of months earlier, and it casts some light on the subject:
<<An unusual procedure, instituted for the first time in the U.S., involved urine testing ot competitors in order to ensure compliance with the IAAF "doping" rule which will govern the Olympics. Just how many were sampled was never announced, but it was far from 100%.
Nor were the results of the tests made public, although it should be safe to infer from the silence that no serious violaters were uncovered. Apparently the tests were not capable of detecting past use of drugs, including steroids of amphetamines.
One coach, whose weightmen routinely take steroids, said, "I believe that most of the throwers simply stopped taking them a few days before their event--that's what mine did. Going off them for a week shouldn't affect the athletes physically or psychologically."
A runner commented, "Some guys take uppers before some meets. But they just help mental stimulation. Nobody needs any extra psych for a meet as important as this." >>
