The truth is, marijuana probably isn't going to make you kill people. Most likely isn't going to fund terrorists, but pot makes you feel fine with being bored and it's when you're bored that you should be learning a new skill or some new science or being creative. If you smoke pot you may grow up to find out that you're not good at anything.
I'm a bit of an abstract figure that people can project their fantasies on; it's pretty much what we all are, otherwise we wouldn't be stars, and people wouldn't be interested. But people project things on you that have nothing to do with what you really are, or they see a little something and then exaggerate it. And you can't really control that.
