^^ Nah that doesn't bring it up. Crappy search engine!
Anyway I think this is the thead... http://www.bluelight.ru/vb/showthread.php?t=227483 at least it covers an acetone wash wish reportedly should get rid of caffeine. Also worth noting is an acetone wash should get rid of byproducts / solvents if the chemist has been lazy. Which judging by the range in colour and relative subjective effects of different powder/crystal MDMA and also powder/crystal speed I've seen I think it's common that crap can be left in the final product. Lazy arse dodgy cooks
^There is so much FAKE MDMA around in Europe these days - people would wash it and end up with nothing at all .
Is open discussion of extraction methods allowed on this thread? IF Ravenousblonde says its OK, Ill leave the instructions here for removing quite a few adulterants.
Extraction methods should probably go over to Advanced DD, just make sure they're not there already. I don't want to put them in here, nobody will look for them in Pill Testing Q&A.
