This is such a good conceptualization, although I'm a smoker myself, I can totally relate to how you have put this together. I hate to admit I am a smoker, and I take this a form of awareness so please continue to motivate people to stop like this.
Driving is dangerous if you do it wrong. Sex is dangerous if you don't use protection. Alcohol is only harmful if you go overboard. But there is no remotely safe way to smoke. There is no safe way to inhale a huge assortment of carcinogens. Nice try, though.
I assume you're a smoker, and that you get angry at the world for pointing out a truth that you don't want to accept. Don't get mad at the world for being honest, get mad at yourself for doing something that you know is bad for you instead of being in denial about it.
