If you can master smoking more than you ever have before, but not passing out, you might halucinate a bit, but not like while shrooming or dropping acid. At that point (being blazed beyond recognition) if your brain wants to see things, your eyes will show them to you. My friend used to blaze about 12 gravity hits and battle deamons. Granted only he knew the deamons where there. But its true, I have seen things before because I wanted to and I was high off my ass.
