I do not think that we should crucify Mr Climberruss. Let's put things into their context. Although doping is recognized now as a form of cheating, no one have accuse Tommy of cheating in any way. It is just that the acceptability of doping in 1939 was not what it is now. Remember than not so long ago, it was perfectly acceptable to drive a car after drinking alcohol, or to smoke in public venues.
I have read a very old version of the Tour de France rules, probably circa 1910, I can't find out the exact reference, but one of the rules was: "Les produits fortifiants ne seront pas fournis par l'organisateur". The "produits fortifiants" are what we would call dope today, they were not explicitly prohibited, they were just not provided by the organizer!
