Another rider was caught. They are all on drugs. Its not a matter of whether they use it but whether they get caught or not.

GOURETTE, France, July 25 ? For a second straight day, a team has pulled out of the Tour de France after a rider failed a doping test. Confidis announced Wednesday it would not start the next stage of the Tour de France after it was found that rider Cristian Moreni of Italy failed a doping test and was led away by police at the end of the 16th stage.
