i would never do that crap, but i watched a friend of mine, swim, smoke some 20x salvia extract for the first time, and he started to dance, but quickly passed out and fell on the ground and pissed himself. someone checked to see if he was still breathing, and he was, and he woke up 30 seconds later. when he woke up he looked around at everyone, didnt say anything, just got his stuff and left in a bad mood. Then he came back 3 hours later and apologized. seems like such a dirty drug to me after that. Any similar experiences?
