Tour De France history regarding doping

I'm currently reading Between Myth and Modernity: A Cultural History of the Tour De France written By Christopher Thompson (whom I may have the pleasure of studying under next year at Ball State University). All of the information below comes from that book (pp. 232-6).

In the last chapter on doping I found this interesting:

On June 28th 1966 the first drug tests of the Tour racers took place in Bordeaux. Mainly it sounds like the tests consisted of looking through racers stuff, checking out their bodies for needle marks and making them pee in a cup that was then sent of to a lab in paris and police headquarters. Reactions to the tests were mixed, some people saying they were welcome and others being outraged like Jacques Anquetil (five time tour winner). Anquetil was more of the opinion that it would be okay for the older professionals to talk to the younger guys about the potential harmful side affects but that they shouldn't have to do anything further because they had proven themselves (the seasoned pros) to be responsible enough to accept any possible negative repercussions and to dope responsibly, if they were doping.

So on the night of the 28th racers seemed divided about whether to submit to the tests or not, some for it, some against it. The next morning though there were supposedly all in agreement that they would protest the drug tests and that protest was led by Anquetil. He said they were unanamious in the protest although some people said they didn't agree to protest and were not even consulted. So anyway, I guess the protest lasted for a few days in which the peloton was riding the stages but not racing. The strike was ended when a racer who opposed the protest took off on an attack. Naturally, others took off after him thereby ending the protest. His manager said, "To take the start of the Tour is to sign a moral contract. You accept the rules and all their implications, or you don't enter race." That racer that ended the protest was Tom Simpson and it was his manager that spoke of the "moral contract." A little over a year later July 13th, 1967 Simpson died on Mt. Ventoux. I haven't gotten through that all yet but I think it was because he had taken some amphetamines and possibly had a heart-attack.

Just thought that was interesting and pretty ironic.
