Is MDA an impurity in MDMA crystals?

[Bragzz]

SWIM has tried MDMA crystals twice now, and is doing them again tommorow night NYE. He had quite a few hallucinations. They weren't everywhere or anything, but every now and again things will seem to move or bend and 3 or 4 times also saw things like staring at a light blue wall inside that had a window, and the wall turned to dark red brick and the window began looking like a window on the streets of New York or something, and in SWIMs mind the TV show "Becker" was being sorta thrown around my head. It was odd, a few other hallucinations have been sorta like that (Like talking to his mate and they'd start to get a facial structure like a type of Cartoon and it seemed more prelevant in his mind rather than visuals, but it did make me "think" it was visual.... extremely hard to explain) but anyway. SWIM heard that MDMA crystals are of course made through clandestine operations, but because it isn't scientists with 100% pure product, there will be impurities. Will MDA be an impurity in the manufacture of MDMA? What SWIM was told was that it was "MDMA".

It's all crystals, from a distance it looks like powder but close up you can see it is actually just smaller crystals (could still be cut... SWIM dunno for sure) see picture. http://disc.420chan.org/mdma/src/1198827916763.jpg
