>>Ingredients in a cigarette.<<

A very partial list. But even ingredients as acetic acid--which I believe is just vinegar--is there for some reason and may seem harmless but, as the host of that site points out, who knows what it does to you when it's burned and drawn into the lungs and mixed with whatever else you're burning and drawing into your lungs with each puff?

I know when I leave a bar after playing an open mic show, I have to shuck off my clothes and shake them out before washing them and I don't dare go to bed without a good scrub-down in the shower. In the morning, I can still smell the shit because it's coating the insides of my nostrils and throat. I have to take a lot of time off between performances because I can't deal with it. I don't know how for the life of me people smoke that garbage day after day after day. I don't let people smoke in my house either. The last time someone did (my brother's wife who didn't even ask if it was okay before lighting up which pissed me off), I could smell it three days later. Smokers don't understand that nonsmokers' sense of smell is far more sensitive than theirs and that it just plain stinks like hell. They don't get it. They act like you're an asshole if you complain about it.
