Because some enjoy smoking, while not being addicted. And there hasn't been a social situation where smoking has been "cool" for a few years now, in fact it is really quite the opposite now.
Ummmm...it still does get started up as a thing the 'cool kids' do in most high schools. 'Cool' or 'rebel' now that it's not considered the polite thing to do.
How long has it been since you were in school?
Considering I'm a teacher.... fairly recently.
It may not be as out in the open and there may be some more negativity around it but it is still what the 'rebels' and the 'cool kids' do.
Choose to disbelieve me if you like, but my information comes from several different areas (rich kids, poor kids, city kids, town kids, farm kids, etc). Admittedly, it's just in CT and Southwestern MA, but I doubt it's hardly isolated to this region.
If it is, do feel free to educate me.
