Being an ardent burley smoker, while I enjoy other genre including Va/Per, I found this a puzzling post. I'm not especially sensitive to nicotine, nor is it strongly habit forming for me. I can go for days without a smoke with no cravings. That being said, I have never associated Va/Per blends with a nicotine buzz. I enjoy their lightness and often spicy flavor, but nicotine seems usually zilch. The one blend I thought of was Russ O.'s Fire Storm, which also has dark-fired, which might bring along some nicotine. I sent my only unopened tin of Escudo to the late great Sante as a thank you for his sending me my first Meerschaum pipe, but I will try some up the road. I think it is difficult to talk nicotine in other genres if you smoke quite a bit of burley in your blends.
