That bud can be salvaged for topicals but if you try and smoke it it's going to taste like a field of hay even if you killed every spore. But where talking solvents, winterizing, saline wash, activated carbon..... do you really want to make use of your plant even if you can't smoke it? I've run trim that got stuffed in a box too soon but I twerked it into psoriasis ointment I could never afford to buy if it was made from oil....
Sorry about your loss, I read to many threads on accidents, last one was 60 grams of oil with vac pump oil on it. Came home and tried to evap my dam solvent that's been sitting since last nice and spilled it into spent green kief... I almost had a stroke i wanted to quit the oil game for a split second.
