I don't know, if this is a language problem, but reading through some of the comments, I don't know if some posters understand what WADA really does.
In German, there is a big difference between "drugs" aka Kokain, Exstacy, Speed etc. (and under certain circumstances alcohol, nicotine, weed) and "doping" aka performance enhancing medicaments.
I know, that in English "drugs" can stand for Crack and Aspirin at the same time, but I think, what some people here have to understand is, that WADA doesn't do tests to find some crackheads, but to look for athletes, who are using perfectly fine substances, which have side effects that can help their performances during competition.
And everyone who says that this isn't a big deal, doesn't really understand how small the gap between a champion and the guy who always come second really is.
In my opinion, if pool wants to be taking siriously as a sport, doping tests are a necessity and if a player can't handle that at any time anywhere, he hasn't understand the signs of time.
