Oh ye of little faith. The dispensaries probably are trying everything in their greedy power to prolong their industry monopoly. Aren't you a dispensary agent Tempe420?!? If I am remembering incorrectly, forgive me, but otherwise you're fear mongering...
There was a recent court case that seems to have clarified the p2p transaction. Don't quote me, and always do your research for required due diligence when dealing with cannabis, but I do believe charges were dropped and a judge indicated the p2p portion of the law was ambiguous. So, like has always been the case, patients and caregivers have worked within the definitions of the law at these farmer markets.
