^ I agree with the rebellious nature of it, especially with the younger generations!
With my mother, she started off doing it because it was "in" and supposedly "We didn't know it was bad back then". Years later, after she had quite for maybe a decade, my father, her ex died and around the same time her best friend died, both of cancer. The stress got to her, and she took a pack of cigarettes that her best friend had given her on vacation and started smoking again. Now, she knows it's bad, she just can't quit.
I hate smoke- the smell of it, the medical implications of smoking (why try and welcome in toxins and cell mutations?). A guy in my neighborhood was walking with me one day, saying hi and he was so attractive- UNTIL he raised a cigarette to his lips and lit up right next to me and my dog. I'm one that is all for banning smoking in public places as well.
Walking around my college campus (mostly nursing majors, ironically), it's like walking through a haze.
