Great answer. Based on the sheer ignorance in this thread, of things like what the difference is between nicotine and caffeine, I don't think most of these people are capable of assessing their own bad habits in the way that all smokers are. I never met anyone who smoked who wasn't conscious of their own vices, and slower to demonize or criticize other people's. Reserving judgment and criticizing your own flaws first is apparently no longer considered a good thing. In fact, I think that kind of conversation is one reason the braindead always want to ban smoking. It is and has always been part of open conversation about the risks of living, personal freedom, and nonconformity.
