Exactly.
However, its always been the same right back as far as the ancient games when they took various supplements.
The guy who won the 1908 marathon enjoyed alcohol during the race...which is illegal in most sports..

Russians used to have a catheter shoved up their privates to put their coaches "clean" urine into their bladder, so that they would pass a test.
Another idiot took steroids, but came off them with a while to go so that he would be clean for the event. However, he was also into blood doping, so was storing his blood in his freezer. As the olympics came up, he reinjected his blood to give him better endurance. Unfortunately for him, his old blood had the steroids , so he got caught on both accounts.
But if you are not stupid, you wont get caught.
Other sports are just as bad I agree, but the difference with athletics is that its mostly a test of physical performance (bar mental strength to perform on the day). Other sports such as football are a lot more related to skill, and not just pure physical conditioning.
