Today someone said something interesting to me, which I knew a slight answer to in my head, but some of the mechanics were a bit fuzzy. The gist of the conversation was about smoking, the damage it causes, and that modern science has been wrong about so many things. It could be hypothesized that since research is at times stood on it’s head and proven wrong many years later… could they be wrong about smoking?

What the biggest thing to fault about smoking that causes cancer? It’s well established that smoking causes many cancers, but the most prevalent (almost the most deadly) is lung cancer

Was Chantix fully responsible for me seeing the light on this one, that smoking - does- cause lung cancer?
