Anybody had it other than me? It seems to be a British thing, although I know it's in Canada and China, not sure about the US.
I had it, it was sold as bath salts for a little while at head shops in the U.S. but I also got it from U.K. and U.S. vendors when it was legal.
Yeah, we used to buy it as plant food before you could get put inside for 7 years for possessing it :/
