The analogy doesn't hold because LSD actually has profound psychoactive effects that people often find positive, and isn't so destructingly addictive. It just isn't the same.

There is a strong difference between harming people as an indirect and unwanted side effect of living in a society you don't have absolute power over, and harming people/yourself by doing something that is completely unnecessary and provides no benefit, like habitual smoking.
So... Smokers smoke for no reason at all? It doesn't make them feel good? People who smoke in moderation (I know many, most cigar and pipe smokers are like this) aren't destructively addicted to tobacco, why can't they smoke?
You talk about people being self-righteous and aren't even reading the stuff you're responding to. I made it clear probably a half-dozen times now that I am making a distinction between habitual and occasional, moderate smoking.
IMO, if you're bothered by tobacco smoke, you probably chose to be (going to a bar or restaurant and sitting in the smoking section), or you live in a very crowded place and it's your own (or your parents) fault that you are forced to be in proximity to the smoke. It seems to me that most anti-smokers are just self-righteous assholes that are bothered by other people liking something they don't.
"Smoking sections" in restaurants don't magically contain the smoke. People who are sensitive to it and seated elsewhere might still have issues.
Seriously, you're just passing the buck here. If you smoke where the smoke affects other people, it's your own fault and you're being rather rude and inconsiderate, or else ignorant of the fact that it does.
Might be untrue elsewhere; but it's definitely not untrue where i live.
Being addicted to something is a turn-off for a lot of people in general. Personally, I don't
like when people are addicted to something, nicotine included, but an addiction is an addiction, so I don't really think they're terrible people for it.
