Hey how do I tell my friends?

If they are true friends they probably appreciate your honesty plus the fact that you respect them enough not to smoke when you are around them. What I hate is these non-smokers who try to tell you how easy it it to quit smoking when they have never smoked once in their life's and don't really know how hard the habit is to break. I should know I am a smoker too and have tried to quit several times now but I still am smoking. Good luck with this situation and have a wonderful day.
