Because there is such thing as occasional smokers, and having a curve of how much it affects them depending on how much they smoke would be helpful, instead of the generic “just don’t smoke” advice that they are already not following.
If you drank a spoonful of gasoline thinking it was something else, you wouldn’t want your generalist to tell you “that was bad for you” and keep it at that. How bad was it ? what effect should you expect at that dose ?
The real point I think is, a binary safe/unsafe is of no help in this discussion where people have wildly different drinking habits. I mean, even kids will ingest traces of alcohol in cakes, should we ban it from pound cakes ?
