(4) (a) A patient may engage in the medical use of marijuana, with no more marijuana than is medically necessary to address a debilitating medical condition. A patient's medical use of marijuana, within the following limits, is lawful:

(I) No more than two ounces of a usable form of marijuana; and

(II) No more than six marijuana plants, with three or fewer being mature, flowering plants that are producing a usable form of marijuana.

(b) For quantities of marijuana in excess of these amounts, a patient or his or her primary care-giver may raise as an affirmative defense to charges of violation of state law that such greater amounts were medically necessary to address the patient's debilitating medical condition.

I think the real issue/debate is going to be settled in the courts. Most patients I've spoken with are not even aware of the clause above, simply put, if you require more than the state maximum quantities in either usable form or in the process of growing, you can use the line above in your defense. "2 ounces or 6 plants was not enough to manage my medical condition" However, until this is settled in the courts you should join NRAD Rocky Mountian Caregivers Cooperative and get connected with the caregivers there to see how they handle this situation.
