smoking kills you, simply put. my mom smokes though. so if you are willingly killing yourself thats basically suicide. but wouldn't it be best to do in a less time consuming way? and then the cancer you'll get from it. thats torture man. just commit suicide the fast and easy way, i.e. a shutgun to the head, over dose, noose, and the ever famous wrist slit. If you're going to kill yourself do it in a way that isn't killing other people, second hand smoke blows @$$.
not that i'd want my mom to kill herself.....heck i'm hasling her to quit.
