Of course you should stop, there are no positives to smoking cigarettes. There is a forum for stopping smoking that might be helpful, personally I'm on a nicopatch and have cut down my smoking by half, at least. But still have a long way to go. I've heard by some, that if you really want to quit, and believe in hypnotism, that it has worked for their mom and dad who were long time smokers. It's great that you are considering the question.
