and its excelent, but swim did a more elaborate acid base extraction and wishes to share, so here goes.
mods: if you want to merge please do, im posting here so that it will get some replies by people more experienced.
the procedure is in the atached file, to big to post it straight away
any questions etc ask away, something swim didnt put in the file was that the basification process was done in an ice bath. Swim didnt want to take the chance of loosing MDMA in the water (well wanted to minimize in any case) both time did it in an ice bath, though isnt sure that it does work.
mind you this does not completely remove active cuts, they all have very simmilar pka's and solubility properties as mdma, but it does help, swim tried the product had a much mellower, less speedy high and far less post roll crash (actually the crash was just an overwhelming sleepiness not the "feel like shit" dopamine crash it usually has)
in any case it was a fun thing to do and at the very least you will know how MUCH of anything you are taking...
