I don't care if anyone smokes, it's their body. Just be respectful when you do smoke. I remember my family and I were out at an open-air restaurant and the guy sitting next to us asked if he could smoke. We politely told him we preferred that he didn't, so he didn't. Simple as that.
This talk of how people perceive smokers has gotten me thinking. People don't look down on people that drink, or at least not as severely as smokers. It's interesting when you think about it.
I think the reason why people look down on smokers is that it's probably the closest of all the legal drugs that is like the illegal drugs. With tobacco the usage and symptoms seem to me to be more akin to that of some other drugs (not saying it is as bad, or that smokers are like heroin users, yadda yadda, etc...). It's more of a selfish drug like heroine or cocaine, people willfully (whether they are psychologically/physically dependent on it doesn't really change that) use those drugs for their own benefit, and their negative side-effects are much more prominent. Wrinkling, yellow teeth (or no teeth), bad smell, skin rashes, all that stuff, these are all associated with the harder drugs. It's this dependency that smokers exhibit that people associate with those other kinds of drugs.
Compare this to alcohol, a fairly sociable kind of thing; you can drink it with friends, you can drink without succumbing to any severe side-effects so long as you know what you're doing, and it doesn't really leave any immediate physical symptoms. You may feel bad with a hangover, sure, but you don't smell or get yellow teeth or whatever. You can get addicted to alcohol like you can with tobacco, but there doesn't seem to be that air of disapproval that tobacco users get because, as I said, it's more of a sociable thing than smoking is.
I dunno, that's just me thinking. It is interesting, though, how people react to two equally destructive substances in different ways. Hypocrisy and pretentiousness? Maybe. I just know I personally don't want to bother with those kinds of things, so I don't, simple as that.
