To be fair to the Hitch's point though, it might be that 'insiders' are much happier to talk about recreational drug use than performance enhancing drugs, because culturally recreational drugs better fit the culture of football (let's be honest, probably most football fans don't consider recreational drug use anything other than a pain in the **** if you get caught), and because if you're taking PEDs that allow you to earn millions of pounds a year, but are cheating, you might be more inclined to keep your mouth shut about it.
You only have to look at the reaction to Kolo Toure's positive - the guy who explicitly took banned slimming pills in order to lose weight when recovering from injury so he could 'contribute' better to the team - and the way he was more or less given a free ride by the game, fans and media because 'they were his wife's pills' (as if, even at face value, that in any way makes it all right), to see that football is a game deeply in denial about the potential for PED abuse.
