Andy Powell and Booze

Why is it that we have rigorous testing of athletes for performance-enhancing drugs, yet when they are in the grips of alcohol or illegal drugs there is almost a tacit understanding that it's merely "a bit of fun"? No doubt, as with Freddie Flintoff, Andy Powell's encounter with alcohol will be normalised and justified, and the serious implication of this incident conveniently igored. The gulf of hypocrisy between the measures designed to regulate doping (and thus maintain confidence in the sports' industry) and the behaviours of some players that are sanctioned and even encouraged, grows ever wider with each high profile incident involving sportsmen. Can we not now have an uniformed policy that addresses ALL inapropriate drug use?
