Opioids Gathering Residue

[spacepirate.x]

SWIM has a pen tube that he has been using to transfer morphine from a surface to an orifice of choice. It's been used a lot so there is a lot of residue. He was wondering if there was a solvent or wash of some sort that could collect it and evaporate or something.

By simply googling your question you would've come across this

One gram dissolves in about 5000 mL water, 1100 ml boiling water, 210 mL alcohol, 98 mL boiling alcohol, 1220 mL chloroform, 6250 ml ether, 114 mL amyl alcohol, 10 mL boiling methanol, 525 mL ethyl acetate. Freely soluble in solutions of fixed alkali and alkaline earth hydroxides, in phenol, cresols; moderately soluble in mixtures of chloroform with alcohols; slightly soluble in ammonia, benzene

So I'd say just wash it with water and let it evaporate over night.
