I've smoked this shit called paralyzing passion fruit a couple times but I stopped for good. It really fucks you up, all you can do is sit there and twitch the whole time, and I've heard a lot of horror stories of the shit. The worse part is this paranoia you get while you smoke it, and for a good 2-3 days after, your extremely slow in the head, it takes a long time to get jokes and shit and you struggle (more than usual for me) to get a strain of thought together and its just overall mental retardation. Sorry if someone already mentioned it, didn't read the whole thread yet
