If you smoked cigarettes for a long time before you took up the pipe, you may not feel the nicotine as much as folks who didn't. I never got any of the head-spinning sickness that I've heard of, I just get the nice, familiar comfort feeling that tells me a blend is strong. I have gotten a small buzz from Irish Flake, but not every time. I'd still consider it a strong blend, though, based on the fact that I felt it. And yes, if you haven't built up a tolerance, best to eat something first... I guess? I really wouldn't know, I was born with a lip full of Grizzly Long-Cut Straight.
