If you are wondering how smoking feels and I hope you are not under aged I don't think one cigarette is going to harm you. The thing is though that many people started smoking that way. Myself included. I wanted to try it out. Then I was out with friends I said, huh! one more couldn't hurt, i ve done it before... and somehow now I am a daily smoker. I guess if you have a strong personality and your friends are not smokers (like my case) you are not doomed to become a smoker just because you smoked one! :) again i hope you are not under aged.
