I'm going to have to step in here. I've almost universally noted that the people who complain about smokers tend to be people who don't smoke, and often never have, and who for that reason conclude that there is no rational reason to smoke, and that people only ever start to "fit in" or seem "cool". This is garbage. The first time I smoked a cigarette was out of curiosity; the second time was because I found the first enjoyable. Smoking is relaxing. It's an enjoyable activity, not an arbitrary one. Which isn't to say that it doesn't have a number of severe demerits - health problems, high cost, and, of course, addiction. (And, yes, many people do only start smoking to fit in, as they do other things.) But it is quite possible for something to be bad for you and be enjoyable - as indeed many enjoyable things are.
