Its the sad truth in many sports and many countries. Especially if it comes to making money or prestige from success in sport. Look at top level athletics, its a permanent battle between using doping and finding out doping. Or the professional cycling - there is probably only few that are not using doping.
And it has been done already 3000 years ago in ancient Greece at the Olympics. In Olympia there are "monuments of shame" that those had to pay for who got caught cheating or doping - and its a whole bunch of those.
