plants that haven't flowered - worth cooking with?

the guy I bought seed from sold me the wrong thing -- it was supposed to be autoflower, but it didn't flower. I don't have a safe place outside or any kind of set up really to finish them on 12-12, so I just cut down the plants and bought new seed from a mroe reputable source (sigh). my question is, is there gonna be enough THC in the leaves without it having flowered that I can make at least a batch of cannabutter or something with them, or am I comletely SOL? (I've had the plants hanging up to dry for a bit now in case I can still get something out of them.)

Sounds like you're SOL.
