An epidemic of drug abuse is destroying sport. The roots of the problem are so deeply embedded that current detection methods don't provide a real solution. 'It's cheating at its simplest.' 'I'm not worried about what is going to happen to me in 20 years time because I've taken steroids.' 'It's heading towards total biochemical manipulation of sportsmen.' Does anyone who hasn't used drugs stand a chance of winning at the Olympics this summer? Can the problem be solved or have the authorities left it too late?
