Take a few Marinols, you'll definite be blasted right out of your mind. (just kidding, it's WAY too psychoactive, I actually hallucinated the one time I took it.)

Actually, you could try recipes so you consume it orally instead of smoking it. It tends to last longer when you eat it and if you eat enough can make it VERY intense. Just try eating a few pot cookies along with smoking a bowl or two.. you'll be blazed for about 6 hours, I guarantee it.
