The hardest thing to do sometimes is to convince you're mom or dad that marijuana isn't dangerous like boos and tobaco are. I suggest that you go to the link that says, The Untold Story, download it into a word document folder, and print it out. Then what you do is make several copies and give one to your dad, or find some other way of convincing him other wise. Other then that, I really don't know what else to do.
