Haha. You're so dense I can't help but chuckle to myself. You clearly have some sort of dellusional mistrust of the government but I can somewhat understand that. "They still have yet to prove it causes any life threatening damage to the lungs." Come on buddy, you can do better than that. Were lungs intended to inhale smoke or pure O2? Do tar-like substances and a bunch of other shit build up in your lungs over time? It doesn't take rocket science, just ask the girl who wrote the topic "Smoker's Cough" up in the General forum. This is one reason why I'm such a big advocate for things like vaporizers. There's a reason you cough, when you inhale smoke. It's the body's natural instinct when it's trying to get rid of something bad in the lungs. Oh an nice job showing me an article that says MJ may be helpful medicinally for some people. Hey where have I said that before? Maybe my first post... Jesus, it's hard trying to argue with people who don't know what they're talking about.
