rather than cutting/making it with other things like alcohol making it, imo, bad ( i know i wouldn't put it in my body and out here in CA there's a big battle going on over the process of making concentrates - basically you're allowed, or what looks like it will end up being, if you keep it all natural - ie water hash and other types, butter, etc or the method i'll describe here).
anyway just literally melt your hash with olive oil or canola oil, olive is my favorite. if it's bud just do what you do with the butter and simmer it (or with trim/shake if not bud) for a bit. it keeps it all natural and works VERY well. sort of imagine it (if you're using water hash, not the gooey hash) like a heroine user melting everything in the spoon. obviously you don't want to heat it up that much you just want to dissolve it and have it bind to the oil/fat.
hope it helps
