I need some help. I have a generally conservative friend who is completely convinced that everyone who goes to a smoke-filled bar more then once in their life is gonna die lf lung cancer, etc. And is working to get smoking in bars and resturants banned in my state :( I've read studies that show second-hand smoke isn't nearly as harmful as the MSM tries to make it out to be, but I've been short of luck finding them online. Can anybody link me to them?
