Are women really smoking so little, or is it taboo to publicly admit that they do?
It's difficult to hide the fact that you're a smoker, so I'm going to guess that women really smoke much less than men in a lot of countries. You can do the smoking out of sight of everyone but I can't get rid of the taste and smell very easily.
This is a good point, especially if it is socially punishable in some way.
Yes, but I believe in some cases, if you don't see it, it is easy to ignore.
