You make kief, then extracts the oil, and mix both together. VERY potent hashish...
firstly, i'm not sure how u make hash from oil. and if u could, that would probably be some GARBAGE
secondly, LOL @ people who don't understand how things work going and trying to tell others how to do things.... clearly this is illustrated by the notion that oil can b turned back into hash...
i've said it once, i'll say it again..... FUCK THE MEDICAL MJ PROGRAMS
full legalization or no thanks.
