Really, any powdered drug could be anything. There is such a vast array of research chemicals out there that are easy to get and produce some sort of trippy-like effect. It sounds like you have a tester, good. Designer drugs these days are more or less like taking a mystery pill or powder. The outcomes are unpredictable. Shi*, I took a bean a few weeks ago and thought I was floating in space and then had a three day hang-over. Never know whats in those pills and capsules now n days.
Anyway, be safe, and always test, and tell others to buy testing kits and test. My guesses for what it could of maybe been is anything from 2ct-7 to 2cb to maybe 5-meo-dmt. Ha, ya never know, its like guessing how many skittles in a 37oz jar...
