drug cheat?

there's an article in today's west australian in which it is stated that the drugs ben cousins has allegedly been taking are, in fact, performance enhancing. a medical authority is quoted as saying that whilst there is divided opinion over whether cocaine aids sporting performance, medical opinion is unanimous that methamphetamines do enhance sporting performance. now, i don't know for a fact which drugs ben's been on, but should reports be accurate then this adds a new dimension to his drug abuse. after all, the fall back line for weagles groupies until now has been that even if he has been on drugs it's only a personal problem and doesn't have anything to do with his onfield performance. this is now clearly not true and should raise questions about any unfair advantages he had in 2005 on his way to winning a brownlow medal. should he be stripped of the medal? hmmmm... that's an interesting proposition. after all, other sports people are stripped of their medals when they're found to have won them whilst using performance enhancing drugs so why should the afl be any different?
