==Opinions as Facts== 
 Hey, I don't write in very often, but I noticed the first picture on this article and was disturbed. It's a graph representing drug researcher's opinion on the harmful effects of various drugs. Are we then supposed to take these opinions based on arbitrary judgments as to what harm is as gospel? I just think it's poor representation that will, to all but the most careful readers, look like some kind of actual scientific study. Wikipedia is a scholarly institution, and we should treat it as such.
