In simple terms, this means that the core right of the qualified patients to cultivate and possess marijuana cannot be abridged.”
And to make Collective grows illegal, is against prop 215
“Qualified patients, persons with valid identification cards, and the designated primary caregivers of qualified patients and persons with identification cards, who associate within the state of California in order to collectively or cooperatively to cultivate marijuana for medical purposes, shall not solely on the basis of that fact, be subject to state criminal sanctions under section 11357, 11358, 11359, 11360, 11366, 11366.5, or 11570.”
