If you've never had the experience of edibles.. Id say go for the cannabutter.. With 9 grams of kief you could make quite a potent batch. If youve already tried edibles, Id say just press some hash out of it and add it to your future bowls. Or if you drink.. you could make a VERY potent tincture with that. In fact you would probably have enough to do 2 of those 3 ideas with 9 grams I would guess.
