Well now, Kevin, because of a time in my life when I was much, much younger, I'm not entirely convinced that "lighting something up, inhaling it, and then exhaling smoke" is always dangerous to your health. In fact, sometimes it's even prescribed by a real live doctor (with a medical degree and everything). ;)

Well, I'll paraphrase...obviously, a few cigarettes here and there won't do a person in. I'm referring to the daily habit.

I'm curious to know why a respected physician would prescribe smoking cigarettes.
