Smoking a triple maduro with high nicotine and a La Flor Dominicana Double Ligero taught me the limit for nicotine. Something funny in my stomach meant I had two seconds to put the cigar down or run for the toilet. Cigars burn more tobacco per puff, thus for me the greater danger. I disagree that pipes offer the least nicotine, or maybe I was more sensitive than I thought, but when I smoked a high nicotine blend, I felt it!
