Although i don't smoke, i posted this discussion because i was asked by a friend of mine if it is ok to smoke an expired cigarette? He told me he opened it a year ago and stashed it somewhere then he just found it yesterday. He asked me if it is still ok to smoke it? First of all i know smoking is not good for one's health so i told him it is definitely No. What perked my curiosity is that do cigarettes have expiry date? Can one still smoke expired cigarette?
