Uh oh, it's the nicotine police!
I mostly smoked Virginia these days, but also smoke burley blends, English/Balkans, Va/pers, and sometimes aromatics. I don't smoke all that many different blends regularly, but the ones I do smoke run the spectrum.
For example, I recall reading that GLP Jackknife Plug was supposed to be a stronger tobacco in the nicotine department, but it didn't strike me as being any different nicotine-wise than any other burley blend. Same with Peterson's Irish Flake.
I've never gotten the kind of nicotine kick from a pipe that I often experience with cigars.
