What? don't tell me you mean shooting oramorph? theres a ton of sugar in there. Best plan probably would be to do an extraction. Might be able to get by with dilution to a nonviscous state then precipitation of the insoluble calcium phenoxide salt, calcium morphinate, using calcium hydroxide (slaked lime, cheap, unsuspicious, or if its unavailable then calcium chloride can be mixed with sodium hydroxide to form calcium hydroxide (fairly poorly soluble in H2O, the less so the colder it gets, and salt. Seperable by fractional crystallization.) But since lime is used in cooking in some things, and for the likes of basing coca tea, chewing betel (VERY popular within the indian community) and other uses besides, its available easily. All over ebay too.)
This throws down, although I've never tried it in diluted linctus, the calcium salt of the phenolic group of morphine, and is used for purifying during some heroin manufacture. If its as good a technique in diluted linctus as in H2O solution alone, then you can regenerate the soluble form of morphine by treatment with a mild acid, such as citric acid, for those that don't want to fuck about with titration, just past neutral to very slightly acid with a PH test pen or PH paper, adding acid slowly in small portions (solution, don't just drop it in in powder) and once very slightly red to basic litmus paper (blue papers), slowly, slowly add a mid-concentrated bicarbonate solution, sodium bicarbonate works just fine, potassium salt should NOT be used, if the stuff is to be injected because injecting potassium salts can fuck with the electrolyte balance if enough be present, and stop the heart), conveniently NaHCO3 is available in good grade at pharmacies. Add solution dropwise, after filtering off the morphinate salt, washing the calcium phenate free of sugars with ice water (save everything until your good and done and ready to make use of the product in case of a balls up along the line, and don't throw all your eggs into one basket either, never a good idea), collecting the filtrate to be reacidified, and then after bringing it to slightly acidic point, bicarbonate solution dropwise, towards the end after an initial portion, with stirring or swirling to mix thoroughly, bring to neutral, and then your left with morphine, in soluble form and sodium citrate, evaporate down using no more heat than the least doable, 40C is alright towards the end, although I suppose I am most likely on the more conservative side, I forget the solubilities of sodium citrate but it should be easy enough to find solvent systems to separate the two. Although its probably not a big deal for small amounts, as long as the salt solution isn't hypertonic with respect to the osmolality of human blood plasma.
