Stimulants white residue from powderized adderall xr

[tweektweekimabird]

hey so i ground some adderall xr (5x10mg pills)) in to a fine fine powder (using a mortar and pestal) and mixed it in to a 8ml vial with 7ml water and 1 ml everclear (to prevent fermentation of the sugars) to allow my self to take partial doses of my prescribed drug ~5mg per ml. There is a significant amount of very fine white powder that has settled to the bottom of the vial. what is this? i doubt it is the the amphetamine because amphetamines are soluble in water.

any ideas on what this white powder might be?
