If you're going to tell other people to "educate yourself," could you at least make a claim that isn't completely idiotic? Also, at the very least, could you cite a goddamn source to backup your claim? I certainly don't use marijuana--or alcohol or meth, for that matter--there's nothing wrong with being a teetotaler in my opinion. But my decision was not made by buying into this kind of fear-mongering.
Also, another short tip to this guy. Don't call someone ignorant and than make a staggeringly ignorant claim.
