Probably one of my favourite quotes about weed, Randy Marsh.

Stan: I've been told a lot of things about pot, but I've come to find out a lot of those things aren't true! So I don't know what to believe!

Randy: Well, Stan, the truth is marijuana probably isn't gonna make you kill people, and it most likely isn't gonna fund terrorism, but… well, son, pot makes you feel fine with being bored. And it's when you're bored that you should be learning some new skill or discovering some new science or being creative. If you smoke pot you may grow up to find out that you aren't good at anything.
