Seriously folks, the physiology is simple, you inhale an agent containing nicotine, formaldehyde, arsenic, benzene, etc., the tar interacts with your airways through the bronchi, etc. where there are helicobacter, bacillus and a few other interesting microorganisms, like candida, their processing of smoke is much more rapid that your alveolar cells, which some are epithelial in nature.

What these microbes put out is bizarre chiral compounds that are not biodegradable.

So when this crap is exhaled to a non-smoker, with unadulterated CTFR and a quite a few other signal transduction pathway gene products did not know to respond, what you all think happens to their microbes?

They die unless they mutate. For some people, it is not a very good thing.

That is why we physicians, scientists and public health officials try to stop it directly.
