i used to do it... regretebly, and it was fun, just stupid. A couple times I did itch really bad, which makes me cringe when i think of the long term side effects (which, i can't say i've really noticed any). The trip is almost purely a body high, you feel like your floating when you walk, and super relaxed when you sit. The best thing to do on it is jump on a trampoline, I swear it's like flying. One time though, the last time, I took a lot and really started tripping, like kind of seeing shit. All I could do was lie there on the floor and watch replays of a Burnout race over and over. Man, I was dumb. Whatever, it really can't hurt to do it like once or twice.
