Following is an interesting article that I saw recently. While I am personally and professionally against "doping" or drug use, I have enough knowlege and experience to know that the issues can be quite complex and aren't as black and white as politicians and reporters try to make it. It is not always clear as to what substances and in what amounts, should be legal or not. Nor is it always clear what tests are valid and when and how they should be administered. In some cases the lines between nutritional supplements, ergogenic drugs, and medicinal drugs are fuzzy and hard to determine. I have generally avoided wading into the philosophical discussions and am not well versed enough in chemistry to argue from that perspective. For me, as a coach, I stay abreast of the legal aspects. It is vital that I know what is permitted and what is banned and make sure my athletes are clear on that.
