That's a very good point Rob about which drugs are acceptable and which are not. Maybe there is a clear definition that isn't evident to the everyday bloke on the street. We will never see a carpet ban will we, not even a paracetemol for a headache.
To play devil's advocate I would still dismiss China a bit though. I would expect sports corruption from China, Eastern block countries and even Italy with a history of huge crime syndicates and previous history of fixing. If caught trying to rig results the next way is help improve results. Again, I am not dismissing the that there no problem in the sport merely saying some of these places are no surprise (excluding Australia of course).
What about darts or bowling?
Isn't that a pre-requisite in darts? I thought a 20% alcohol blood level was the level required before you compete!!!!!!
