Doctors like Lipworth know nothing about the methods used by the doping doctors. And that is not a criticism of them, but it does mean they get drawn into things they don't understand. A doping doctor knows how to dose and stack different compounds for best effect. They are miles ahead of doctors like Lipworth because they specialise in making people faster and stronger, without any concern for breaking protocol or rules.

So when they make comments on performance enhancing effects of drugs like Salbutamol they end up playing to the deceptions carried out by the doping doctors. Lipworth may know about Salbutamols effects in sick people but its easy to drop the context and apply it - wrongly - to athletes.
