I just want to pick up briefly on the effect on the lungs. Obviously, smoking anything is not good for anybody. I, myself, am quite convinced of that. But bronchitis—cough, phlegm production—“itis” refers to inflammation. Inflammation is strongly associated with cancer development. I would think heavy users are going to be putting themselves at risk.
I want to take it away from cancer, because that will divert us. We need more evidence.
In terms of other organs, there's evidence, as I understand it, of decreasing male fertility. Can anybody comment on that? Is anybody aware of that?
