I have been smoking a pipe (after a long hiatus) for a year now, smoking cigars 6 months, and just started using nasal snuff. What does a nicotine hit feel like? With my first smoke last year, I felt dizzy and nauseous which I suppose was from nicotine, but that happened once maybe twice. Beside that, nicotine seems to do nothing for me. I drink coffee also and caffeine does nothing to me either. Any thoughts?
