(2) Is engaged in the medical use of cannabis; and
(3) Possesses, delivers or produces cannabis only in the amount described in paragraph (b) of subsection 3 of NRS 678C.200 or in excess of that amount if the person proves by a preponderance of the evidence that the greater amount is medically necessary as determined by the person’s attending provider of health care to mitigate the symptoms or effects of the person’s chronic or debilitating medical condition; or
(b) Is a person who:
(1) Is assisting a person described in paragraph (a) in the medical use of cannabis; and
(2) Possesses, delivers or produces cannabis only in the amount described in paragraph (b) of subsection 3 of NRS 678C.200 or in excess of that amount if the person proves by a preponderance of the evidence that the greater amount is medically necessary as determined by the assisted person’s attending provider of health care to mitigate the symptoms or effects of the assisted person’s chronic or debilitating medical condition.
2. A person need not hold a registry identification card or letter of approval issued to the person by the Division or its designee pursuant to NRS 678C.230 or 678C.270 to assert an affirmative defense described in this section.
3. Except as otherwise provided in this section and in addition to the affirmative defense described in subsection 1, a person engaged or assisting in the medical use of cannabis who is charged with a crime pertaining to the medical use of cannabis is not precluded from:
(a) Asserting a defense of medical necessity; or
(b) Presenting evidence supporting the necessity of cannabis for treatment of a specific disease or medical condition,
if the amount of cannabis at issue is not greater than the amount described in paragraph (b) of subsection 3 of NRS 678C.200 and the person has taken steps to comply substantially with the provisions of this chapter.
4. A defendant who intends to offer an affirmative defense described in this section shall, not less than 5 days before trial or at such other time as the court directs, file and serve upon the prosecuting attorney a written notice of the defendant’s intent to claim the affirmative defense. The written notice must:
(a) State specifically why the defendant believes he or she is entitled to assert the affirmative defense; and
(b) Set forth the factual basis for the affirmative defense.
A defendant who fails to provide notice of his or her intent to claim an affirmative defense as required pursuant to this subsection may not assert the affirmative defense at trial unless the court, for good cause shown, orders otherwise.
