I don't inhale...no, not quoting a certain ex-president...at least not pipe tobacco. Never smoked cigs (unless you count those 12 or so when I was a sophomore in HS...), so I never developed the "talent". I do, however, get a vitamin-N kick from time to time from the pipe. By drawing smoke into our mouths, and sometimes exhaling through the nose, we pick up nicotine through the mucous membranes in the mouth and nasal passages. So we don't need to inhale (which is not a pleasant experience with a pipe IMNHO) to get our nicotine.
