Pot, mushrooms, acid.
I quit doing acid though. If you do a LOT of acid in your life (which I have), it can affect your internal organs. I started feeling some pain in my pancreas when tripping, and a friend who had likewise done much acid in his life ended up hospitalized with pancreas problems, so I decided, pancreas > acid trips. If I didn't have that problem I'd probably trip my ass off at Bonnaroo this weekend. Since I do have that problem, I will instead search for some mushrooms. ;)
