Sorry for my ignorance. But if AVB = 'already vaped bud', no in my opinion. Throw that shit away if you dont know of any OTHER use of it. Other than that, ya, I would use whatever trim or bud I have.

Same when I am making concentrates. There is no use of adding impotent material that can add to an adverse taste/flavor. In a tincture, that might not matter so much. Because a tincture is usually such a small amount and can be chased with something. But when dabbing a mixed concentrate, taste might matter to more people.

If potency is your goal, throw the AVB in trash, mix whatever trim and bud you have, and go hard. The AVB will only add to a horrible taste.

My uneducated opinion.
