removing alprazolam from PG to another solvent

[Someone13232]

i have 1000mg/100ml solution of alprazolam (Xanax) in propylene glycol, but i would prefer to have it in acetone or isopropyl so when i dose myself by dropping it on sweets it can soak in and dry out and i can prepare doses for future use. i have previous experience with dosing myself using isopropyl on hard sugar sweets and drying it out, but TL;DR i wanna move it from PG to acetone/IPA, is there an easy way to do this or will i have to put up with annoying gloop

Try mixing a small sample with water and see what happens. Theoretically the PG should mix with the water, leaving alprazolam behind as an insoluble precipitate. That's in theory, at least.
