I think doping is impossible to control and will become even more so in the future. (Genetic engineering and all). I also think that the term 'perfomance enhancing' is rather invalid. Hard training is performance-enhancing..so is a proper diet and the various (legal) supplements. There is, though, the moral issue of people ruining their bodies by using steroids, etc..but you could argue that it would be easier to control if it was legal. Jakob
