Yeah, okay.
You see.." Each organization will specify within its rules the length of time that its athletes should be drug-free, which may vary from testing clean on the day of the event, to being drug-free for a number of years, right up to a lifetime natural requirement" -wikipedia.
So as always, you can use drugs, but you have to be clean when tested, just like in any other sport. Life time natural...how do you prove it? You say so, because there is no way to know if it's true or not
