When in doubt, throw it out. In other words, don't do anything that you believe will change your mental state or the developement of it. STOP doing coke it will ruin your life. If I had to choose between the two I'd say smoke a little MJ and see how it feels. And when I say a little, I mean like one hit and wait about a 1/2 hour before you do another. (not in your parents home! In the backyard or somewhere you feel safe and secure.)

My :twocents: worth. Best of luck to you!
