It's interesting that so many are up in arms about folks smoking, which is legal, but don't see a problem with sticking needles in your body to inject illegal substances.
I hate ciggarette smokers who light up in my presence AND HAVE THE AUDACITY TO BLOW IT ALL OVER ME OR LIGHT UP IN MY CAR!
That being said, I've never lit a cig or took a dip, though I do light up some herb on occasion to help with appetite.
