a drug that can seriously mess you up. some say it comes from the eggs shells of turtles from madagacar so that's why it's so hard to get, but others claim it's made by heating up a very rare certain type of fungus, one that when it is heated, takes a form similar to that of the shell of a turtle. taking one turtle shell can greatly increase dopamine uptake in the brain and send the user on an unbelievable trip. there are no known addictive properties, however there can be damaging long-term effects to the brain and CNS.
Man, I did turtle shells last week, and it was the most insane trip I have ever been on...I was absolutely shell-shocked.
