Trying to Understand... Ketamine is also a salt, so wouldn't it not be soluble also? Or do you mean the base will be soluble and none of the salt. Since, I presume Ketamine is only a salt once dried out as a Hydrochloride. I understand chemistry better than OP I believe, but using Isoproponol would leave a lot of HCl behind, but the Ketamine base actually makes it thru? I'd like to be able to clean my K similarly to how you can clean your dirty "champagne" or "purple" MDMA. I would think some of what's in the coffee filter would be ketamine and not only salt. Please correct me if I'm wrong.
PS-I'm a bluelighter that hasnt recovered his account yet
