Both do that though
So what you're implying is that smoking marijuana has no negative effects on its user at all? Cause if you are you're wrong, I understand that its being used for medical purposes, but thats in small controlled doses, that hippy guy does not look like he's suffering from any medical problem whatsoever. Both Cigarettes and Marijuana will end up killing anyone dumb enough to smoke them, sugarcoating either is wrong.
BY THE WAY: This is the Art Portal not the poorly done propaganda portal
