How come Marion Jones was not tested +ve for perf enhancing drugs durng 2000 Olympics in Sydney?
Yes, athletes are tested in and out of competition. She was tested several times at the Games. Conte, the owner of Balco had designed a new drug that the testers could not find. Usually the scientists will design a new drug that does not have the same molecular structure so the computers do not recognize it. Someone sent a needle of his drug to the agency which is how he was found out and his empire crashed. The druggies can stay about one year ahead of the testers, so it is a game for them to keep making new drugs that can not be detected. Athletes are tested randomly out of competition and the medal winners plus a few others are tested in each event.
