If I do a CWE on some tablets, then I'm left with just codeine in water (in theory) can I then reduce the liquid left with a little heat (not enough to damage the codeine) I'm talking near a radiator or something? Or will codeine evaporate? How far could you take this as well? Could you evaporate the water entirely and be left with codeine phosphate powder you could put into capsules and use as a pure codeine pain killer? Purely wondering for harm reduction.
