I went around my apartment and got rid of anything tobacco-related. My cigarette machine, 5 bags of tobacco, countless boxes of tubes, lighters galore (except for 2 zippos and a torch-type), and cigarettes bought. A little less than 2 months later I found half a pack in the back pocket of my passenger seat. I smelled them, thought about lighting one up "just to see" for a moment, then abruptly crushed them up and threw them out with all the other rubbish as I was cleaning out my car. That's as close as I had gotten to lighting up.
I admit, it still smells good for a brief moment when you walk past smokers, but when you think about everything you may have gone through in your life (i.e. gasping for air, pneumonia, bouts of bronchitis, asthma, etc.), you tend to keep walking, pull out your PV, and take a hit with a smile.
