I started smoking when I was 14 — sneaking occasional cigarettes from my parents, or buying packs from a cigarette machine. By the time I was 16, I was a daily smoker. Over the next 40 years or so (I’m 59 now), I smoked approximately a pack a day. I tried quitting several times. Was in the test group at UCLA for the first nicotine patch. I stopped for about eight months that time, but it was difficult every day. Tried cold turkey, and that never lasted more than a few days. Tried Chantix, which really did help to reduce cravings, but I did not quit entirely. So I would have to say that every effort was unsuccessful. When I got my first e-cigarette, about four years ago, I didn’t touch a real cigarette again for nearly a year; just didn’t feel the need. I still don’t have to, but the person who lives with me smokes, so I do take puffs from his cigs in the evenings. If he were to stop smoking, I would be perfectly fine with only the e-cigarettes. If I weren’t able to get e-cigs, I am quite sure I would go back to smoking real cigarettes, which I hope never to have to do because of the expense, the smell, and the health risks to myself and others.
