I lived in Vegas in the early 70's and we used to get this stuff sold as "THC"...it was a whiteish kinda stick together powdery substance we ingested and yes, it got one very high...I never met the Cosmic traveler, but it was sold to us as coming from him. Buying on the street, who knows if it was real or some other substance...I never saw it again after I left Vegas in '73.
