No, don't play games with me. You made a post that seemed to suggest you believe that smoking doesn't cause lung cancer, and you lauded another poster for saying so explicitly. So don't play games and answer the question: Do you believe that cigarette smoking causes lung cancer? Yes or no?
"Do you believe that cigarette smoking causes lung cancer? Yes or no?"
No. It may increase the risk factors of contracting lung cancers, or other diseases, but it is not a causal factor. Genetics is far more influential in contracting lung/heart disease.
Now, how about offering your answer to my question. Why is the highest per capita population in the world, Japan, also the lowest per capita heart and lung disease incidence in the world?
