It was an acid/base extraction - I haven't extracted DMT for a long while now (well 2006) since i got soooo fucking frustrated because of the "mysterious crappy trip" i'd get every time, has the quality been better now? Seems like no matter what supplier it seemed to be still shitty so i just gave up.. When i FIRST started extracting spice, my friend analyzed a sample and he said it was so pure (99%+ LCMS) he'd use it as an analytical sample.

I think i was especially sensitive to the crappy stuff though.

One time a supplier sent me many small samples (he'd grab a handful of bark from each 10kg box he had) to test (not analysis just smoke test).. Each sample would be wildly variable from the next.. A few times I extracted, i ended up with grams of a pure white DMT looking pile of crystals that were *totally* inactive smoked.. I know it wasn't just me because I gave grams of it away to friends and nobody got any effect out of it.

It seems like when I first started extracting, every batch of spice was all perfect..no dark trip and very potent. then it just suddenly changed.  I suspected for a while maybe all the suppliers were getting it in bulk from the same large supplier and they were selling the wrong species or something, i dunno..
