Oh come on people... THIS is the reason there is no smoking in games: you have apparently all bought the 'smoking will kill you indiscriminately'-bullsh*t.
Don't misunderstand me now: I know smoking is unhealthy and has a great number of adverse effects, most of them long-term, but so does alcohol. Just as with smoking, the problems are caused by excessive drinking, not because you have a beer before you go to bed or the occasional drinking binge a few times a year. Smoking does not HAVE to be excessive, which is what you all apparently assume (and which is what has been rammed down our throats for a decade or two).
Doctors will tell you that the occasional cigarette, while not healthy in any way, is not going to KILL you. Just like having a glass of wine with your dinner isn't going to cause your liver to die.
Again, I'm not saying you should smoke or drink or that it's not bad for you, I'm just saying that you need to at least THINK about what kind of propaganda you are repeating. THAT is the reason there is drinking but not smoking in games and popular culture in general. Put things into perspective instead of mindlessly reciting what you've been told.
