It seems like if you dissolve the cocaine HCl in a little water, you can then filter out the AC as it doesn't dissolve. Then just dehydrate it again. If you use 2 ml of cold water, say 5-10°c, everything that doesn't dissolve is not cocaine, so decant the Water and leave any junk behind. Dry the sludge and see how many % of your starting weight you cleaned out of it
