Are you a cigarette smoker, or regular chewer or dipper? That might explain why the nicotine didn't whack you upside the head... maybe you've just built a tolerance.
I would not recommend inhaling, although some certainly do. My understanding is the alkalinity of cigar and pipe tobacco smoke is different than that of cigarettes, and is absorbed quickly through the mucous membranes of the mouth, rather than the lungs as with cigarettes. Even having smoked cigarettes for a short while many years ago, the couple times I've relapsed I've had no problem inhaling... but man a cigar just chokes me up if I breathe a bit in by accident. HARSH stuff.
I for one enjoy using Swedish snuss tobacco when I can't fire up a cigar or pipe, and have built up a bit of a tolerance that way, but stronger cigars and pipe tobaccos can still get me a trifle woozy, especially on an empty stomach. I can tell if a smoke is a strong one by that good old "lead ball in the stomach" sensation also.
