If you really want to salvage any remaining actives...you could save it in a mason jar until you have a good quantity, grind it down to a fine powder and let it soak in some 190 proof liquor. That is if you can get your hands on some 190, at least 95% ethanol. Soak it for a few days up to a week, filter and let the ethanol evaporate. Vape whatever you're left with and you might get stoned.
You could also try a butane extraction which is more complicated, do a good search for instructions.
