Do Hobbits get Lung Cancer?

[Legate of Amon Lanc]

You know the so-called "Churchill syndrome"? People with that can smoke like a factory and nothing happens to them. Maybe the whole Hobbit race had this.

Or, maybe Old Toby cultivated some sort of pipeweed that was not harmful in any way.

(Gandalf and Saruman also were smoking quite a lot and we never see a scene like "Théoden, my friend, let us forget old *cough cough* sorry, Théoden, join me *cough cough cough* oh no, the Voice ain't working today. Worm, throw the Palantír on them at once!"
Though, Gandalf and Saruman were Istari - they could have had some resistance. But what about the Rangers? Well, they were Dúnedain, so maybe... The Dwarves? No problem, Dwarves are tough. Okay, so the only people who could have had problems would be the Breelanders. Like Bill Ferny. At least he was spitting all over the place. If it was due to the pipeweed, we don't know. But if yes, then that implies that sometimes smoking was not as pleasant. But that does not necessarily prove anything. Maybe his pipe was just a bad one.)
