If Sharapova got banned for a mix up and something not really performance enhancing should more be done in football?

Interesting report here about a number of players caught in the 2010 World Cup especially with Coke and Ecstacy but never heard anything in the media about bans.

How can salbutamol be a banned substance its so widely used!
