I began using an e-cigarette in October 2009 and I haven’t smoked a combustible cigarette since December 2009. Let me say that again. After 30+ years of smoking, with no intention of quitting, use of an e-cig replaced my smoking. Completely. I don’t smoke anymore and I don’t want to. I don’t cough. I don’t wake up choking. I can smell flowers. I can taste the wonderful variety of flavors, both in food and in the liquid I use in my e-cig. My blood pressure has decreased 10 points, my hemoglobin has decreased to the middle of the normal range. I use about 1/3 of the nicotine that I needed when I started, but that was inadvertent too. I haven’t smoked since December 2009. It feels good.
