Max possession under the law?

[DenverRelief]

(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.

It's true that this can be an affirmative defense, but the doctor's approval for more medicine is not indicated on the license itself.

Should you get caught with more, you and your doctor will likely have to testify to the medical need that requires more medicine.

It's a legal hassle that would be best to avoid unless absolutely necessary.
