Strictly speaking those so called "games" COULD actually be thought of as not so much a "sporting event",
but to a quite substantial part also as a "pharmaceutical event". (?)
Of course one should never ever assume or seriously think of those events of being like that, of course not! =>
= good citizens. 
Also what happened in this regard at all those games (winter & summer editions) in the past should absolutely be forgotten or even
much better simply not been noticed, seen or heard when anything happened at the time....
The previously used word "COULD" just simply implies that it could be a ("a very distant"= very unlikely) possibility, right?
Just some totally random thoughts, certainly no assumptions but maybe food for thoughts &/or further elaborations.
P.S. About professional cycling: I've once heard that a prominent doctor said that there was a not very visible Chinese or Japanese man
(mostly hidden) but nevertheless present at any international race &
that without him they wouldn't be able to organize/hold such high competitive events.
The old "dude" is apparently luckily still alive, ubiquitous = allover the place and over 90 years old! His name is "Do-Ping".

to understand my above message.
message then you sadly are in the same category of...)
