If you keep cigarettes around your house, you will smoke them. If you go out to parties where people are smoking cigarettes and drinking wine, beer and alcohol, you will too. If you hang around with people who smoke all the time probably you will too. If you hang around with people who smoke cigarettes and do heroin you will too. The moral of the story is.... don't keep cigarettes around your house. Don't go to parties where people smoke. don't hang around with people who smoke. If your friends smoke get new friends. Most of the world doesn't smoke and it is easy to find friends who don't . Birds of a feather flock together. You probably already have friends who don't smoke. In fact most of your friends don't smoke. Go to their parties. Heck, throw a party of your own and just invite people who don't smoke, tell them it is a potluck. I bet the food will be great.
