Why more women with husk voices, despite less smoking? - why do some girls have husky voices

There was a time, the years of smoking, women often have a hoarse voice, which seems to always get to them a voltage, the words in the throat, and any effort to increase the volume to a sharp increase in height.

Today there are only a fraction of the number of smokers, but often I hear a girl or a woman with this problem. For some reason, there are some broadcasters who suffer from this situation.
Still sounds like such an effort to speak for them, almost like they have laryngitis.

What led to this?
Can anything be done to heal them to talk normally?
Everything should be what a person or not (other than non-smoking) in order to prevent this?
