Puff Puff

No one in my family smokes. But my hubs used too. And I know that he has times, when he has urges to have "just one" cigarette. But I'm glad he doesn't give in. People who do smoke have such a difficult time in quitting. People struggle with it greatly. I have several friends, who will stop, but as soon as life gets stressful they immediately run back to cigarettes. I've seen some different things on the news about an electronic cigarette. I wonder how well they work?
