Do Hobbits get Lung Cancer?

I'm not a smoker, and never have been, but I was under the impression that the main hazard from smoking is thought to be the tar content of the smoke. At any rate, since the implication is that the herb Nicotiana is analagous to our tobacco, and the physiologies of Men and Hobbits are very close to ours, any potential dangers ought to be the same.
Then, I have to wonder if the Dwarves were susceptible to the disease Black Lung, which afflicts those who work in mines. Dwarves were smokers too, so they should have been dropping like flies. That is, unless they, like Elves, were invulnerable to illness. But that's another topic.
