I dont smoke, never have smoked a cigarette in my life (note - cigarette). Ive smoked a pipe and cigars before while working in the mosquito woods of N. Minn.
Anyway, I was on vacation a couple weeks ago and was watching a tv show bout 4pm (wont say the name) and they had a dr. on as the guess. he was there showing body parts that had been taken out of peoples bodys after theyd died. They showed a lung w/ cancer nodes on it. IT WAS NASTY!!! If I thought I could dig up that picture, I would and post it. If that sight wouldnt convince you to quit, Im not sure what would.
