Making Cannabutter with ABV pot

Does anybody know what kind of butter to already been vaporized pot ratio I need to use when making cannabutter? I have about 5-6 oz. of ABV pot and I need to know if it's even worth using for some butter yet.

I wouldn't use only vapo'd weed. Use it in conjunction with non-vapo'd weed to get best results. But if you insist, I read somewhere that after vaporization, the weed still holds roughly 30% of the THC (pending you aren't vapoing it black!), so you do the math and figure out. If this isn't true, someone please let me know.

Sounds good. I'd throw in at least an oz. of decent buds into the mix, at least to make it taste good.
