Cigarettes, the paper and filters are loaded with chemicals. That's probably what's bad for you. People smoked pipes for centuries and nicotine has many positive benefits. 

Both my parents were heavy smokers.  Growing up and living in the same house, and being in the same car with them when they smoked was very difficult for me.  The smell was hard to take.  For me, it only detoured from ever smoking myself and doing this to my future children. If I would of taken up smoking for some reason, I would not of blamed them, it would of been my choice but it made not want to !

I also would never take up smoking because of the second hand smoke issue.  It's been proven that it's not healthy to breath in and does harm.  If your living in a house and driving in a car with smokers, it's very difficult to not be exposed. , and to do this your whole life growing up, would more than likely cause some harm to yourself.  In this regard, It could be a sin for parents to smoke around their children.  I once had a priest tell me that smoking could be a sin if it is destroying your lungs and making your body cariogenic, which is cancer causing.  He say's your body is a temple of the Holy Ghost, and you need to do all you can to prevent harm to it because of this.  Smoking harms your body in many ways.  Just something to think about!
