Concentrates of marijuana by Az definition is not marijuana it is Cannabis when it is extracted...
I have always believed extracts were illegal under the AMMA...
AMMA -
"Marijuana" means all parts of any plant of the genus cannabis whether growing or not, and the seeds of such plant.
"Usable marijuana" means the dried flowers of the marijuana plant, and any mixture or preparation thereof, but does not include the seeds, stalks and roots of the plant and does not include the weight of any non-marijuana ingredients combined with marijuana and prepared for consumption as food or drink.
No mention of Cannabis (Concentrates) in the AMMA
