Escudé and Mutis smoked quite a lot, afaik
Wertheim mentioned in an article some time ago that Grosjean smokes, so now he is always mentioned in that regard. I guess he just used to smoke once in a while, I don't know if he still does. No way he's smoking as much as some people are saying.
But it's true too many French players smoke - and so many coaches and former players! It's crazy.
