Allow me to go all RD and shit for a second, but second hand smoke was an easy explanation for people who ended up with lung cancer who never smoked. Oh, you must have been around a smoker??? No, oh, ever been in a bar with smoke??? Oh, you have a severe case of second hand smoke. Lung cancer, I don't buy. Emphasymia and other respiratory/health issues, by all means. And like I said, I'm not a smoker and never have been.
P.S. Bring your pussy ass BB UZI in my direction Brown, I'll find some big titted girl to bust a cap in your Canatard ass!!!
When we see your medical degree, we can listen to you about second hand smoke. Until then, get an education about the subject before you post.
