Reading about the folks wanting a cigarette. I can totally empathize. The odd thing is... Since I bought my Lavatube, I haven't had one... I think it may have helped me that I have been smoking ultralights for a year now to cut down. When that feeling comes over me... I grab the lava tube & set it to 6v and take a couple heavy pulls. I no longer want a cigarette.. in fact, no longer do I want the Lavatube... LOL.... In retrospect maybe 16mg was a bit more than I needed...
