Errm,
http://en.wikipedia.org/wiki/Sibutramine ,
its basically, as it says there if accurate, not an abuseable drug and isn't really required to be a controlled substance.
From what I can tell, its got potential for a similar effect to an antidepressant and an appetite supressor, it also mentions it has a half life of 1 hour so I can't imagine you can even have it in your system for all that long. Although whatever its metabolised into maybe stays in your system for a while and thats what they tested for.
But, its not a performance enhancing drug, doesn't seem to be anything more than a possible serotonin increasing substance.
So before you all jump all over him, about the worst thing the substance does is supress apetite, should we really be banning people for that. Not quite sure how its helping him beat the opposition, nor is it a narcotic. I really can't see a reason its banned in the first place other than being a fairly risky drug in terms of side effects and complications.
This isn't a "bad" weight loss drug that raises your metabolism and maybe gives you more energy, like ephedra or something, its something that just helps to suppress apetite. For all we know he's had a life long problem controlling his weight which obviously for an athlete is a problem, maybe he suffers from depression due to the pressure to maintain weight, who knows. But the drug simply is not giving him any advantage on the pitch, nor is he abusing cocaine, which also won't give him an advantage but is bad for the "image of football", obviously ignoring letting Marlon King and Barton continue to make money in football.
