straight edge (sXe)consists of the 3 X's
X- no recreational drug use (includes caffeine- which is a stimulant drug; some will accept drugs such as codeine or morphine for medicinal purposes)
X- no alcohol (some go as far as no Ny-Quil or Day-Quil because they include alcohol)
X- no casual (it doesn't mean abstinence, it means that you won't have one-night stands, but will wait until you are in a commited relationship to have sex.)
People have associated sXe as gang affiliation, but it is a way of life such as vegetarianism or celebasy. it is a way of life that consists of not poisoning your body with ignorance and sustaining a healthy lifestyle.
i am straight edge and for all the people who think it is the "popular" thing to do, you're wrong, and should accept it as a good thing because atleast there will be a few less drug-addicts, alcoholics, or AIDS carriers coming to a town near you!!!!
