When I say less damage I don’t mean none, because tobacco smoke can cause
cancer in the mouth as well as the lungs. Also, even though you aren’t inhaling
smoke directly through the mouth to the windpipe, you are inhaling it through the nose. Otherwise you wouldn’t sense any aroma, and the aroma is most of the pleasure. In effect, you’re breathing your own second-hand smoke. So you’re probably spending some of your quality life time and time to disability on tobacco use and enjoyment.
