Smoking is stupid. I can't for the life of me even figure out why people take it up. I mean WHY??? And as far as I can see, smoking tobacco doesn't make you high or even give you much of a buzz??
I'm sure it does SOMETHING... but I've never figured out what.
Just... don't do it. There are NO ADVANTAGES to smoking (at least none I can think of). It will make you stink, make your health bad, and can be quite expensive.
