Pro to the question "Should Performance Enhancing Drugs (Such as Steroids) Be Accepted in Sports?"
"There is nothing 'unnatural' about PEDs [performance enhancing drugs] because there is, in reality, nothing that is pure or 'natural' about any sport, sports being wholly of human devising. Even in the purest imaginable competition - say, just throwing a weight - training, learning, and coaching will materially advantage one competitor over another. Why are those 'natural' and PEDs 'unnatural'? If the argument is that they are 'unnatural' because they cause changes in the athlete's body, then the whole edifice collapses under the weight of its absurdity, because training, diet, and such universally accepted aids as Lasik surgery, aspirin for headaches, ice packs for limbs, 'Tommy John surgery' - and a like laundry list that anyone can readily extend - also cause athletically significant changes in athletes' bodies.
There is simply no plausible case, ethical or practical, to be made for prohibiting [steroid] use, not in law, not in sports-organization codes..."
