I may have eluded to or described some processes, but the credit for them should definitely go to David Lee. He uses acetone extensively in his procedures in "The cocaine users handbook" which is available free in 5 places at least and is everything. If youve read it, you know a lot about cocaine (unless you are forgetful) and it's hard to know much without reading it. It's easy to kmow the theories, but he turns theories into procedures, like, "How much hcl does it take to make base cocain back to hcl? 0.25ml and you should add 0.25ml of methanol iso and 0.25 ml acetone to it, to dilute the acid add the mixture of 0.75ml to your base dissolved in acetone to precipitate the hcl. Now you know how to doit without having to bubble hcl gas or wondering what are the best solvents ratios. if you stir the two liquids vigourously, and dump the acid mixture into the cocaine, and dont stir it at all or one bit more, tomorrow you'll have beautiful equal size crystalls of very very pure cocaine hcl. that x100 in the book
