I once had about 80g of vaped plant material everyone said was useless or whatever. I held to the idea that even if there was 1% of thc in that there is still 0.8g of 100% THC in there. I did a butane extraction and ended up with about 2g of BHO as no extraction is 100% efficient so there is always "something" left there and its just a matter of getting it out.
I suppose you could make edibles with it but you may want to run some kind of extraction first to end up with a more workable and understandable product. Best of luck!
P.S everyone at the head shop my g/f worked at the time said i was silly for thinking it would work, they were silly for thinking i was silly in the first place! Just because we had a good vaporizer and followed instructions doesnt mean its a 100% efficient extraction always remember that.
