Had I continued smoking them, fags would probably have shortened my life by about ten years as I had smoked them for about thirty years.
Two and a half years ago I exchanged them for an e cig. I’m still a nicotine addict but I can feel the difference in the delivery method every day in my lack of cough, higher fitness, skin condition, dental health and so on.
Nicotine is highly addictive but probably only mildly harmful.
Vaping will improve the lives and extend the lives of millions of people who would otherwise be unable to stop smoking because they can’t overcome the addiction.
