Drugs, Tour de France, Olympics......

The Tour de France is finished with a new champion. I am sorry to see that Cadel Evans missed out on the win and yet a mark of consistency to finish second two years in a row. A noteworthy feat that few can emulate.
Drugs marred yet another year of racing and even the final day featured a drug bust. and now heading into the Beijing Olympics, drugs are yet again a feature of the news.
Top US breast-stroker Jessica Hardy recently tested positive for a banned substance. 1 in 4 Australian athletes expect there to be drug cheats competing in Beijing, with swimmer Grant Hackett saying "it would be naive to think the games will be clean." The head of the World Anti-Doping Agency, John Fahey is confident of a 'cheat-free' games despite continuing doubts about the effectiveness of blood doping tests.
Are the drug cheats still one step ahead? Are there nations that still dope their athletes secretly as in the East German regime of the '80's. I recently watched a documentary on the sad effects on East German athletes now 25+ years post-drugs. Athletes permanently crippled and in constant pain, women that have undergone gender change because of the effects of the drugs.
Is short-term glory worth this pain for those knowingly taking steroids for performance enhancement?
