I no longer smoke as much as I did before. But whenever I get stressed or when I'm with friends, I smoke a few sticks. It's nowhere close to the 2 packs/day I smoked before. But when I caught up with a few of my college buddies, they were into e-cigs. They said it was not harmful and they still get to enjoy the effects of nicotine. I'm not sure about getting into it. It seems more expensive for one and there have been articles written saying it's not as good as formerly thought.
