(a) Except as provided in § 4904A of this title and this section, an individual may assert a medical purpose for using marijuana as a defense to any prosecution of an offense involving marijuana intended for the patient's medical use, and this defense shall be presumed valid and the prosecution shall be dismissed where the evidence shows all of the following:
(1) A health-care practitioner states that, in the health-care practitioner's professional opinion, after having completed a full assessment of the individual's medical history and current medical condition made in the course of a bona fide health-care practitioner-patient relationship, the patient is likely to receive therapeutic or palliative benefit from marijuana to treat or alleviate the individual's serious or debilitating medical condition or symptoms associated with the individual's serious or debilitating medical condition.
(2) The individual was in possession of no more than 6 ounces of usable marijuana.
(3) The individual was engaged in the acquisition, possession, use, or transportation of marijuana, paraphernalia, or both, relating to the administration of marijuana to treat or alleviate the individual's serious or debilitating medical condition or symptoms associated with the individual's serious or debilitating medical condition.
(b) The defense and motion to dismiss shall not prevail if the prosecution proves that
(1) The individual had a registry identification card revoked for misconduct; or
(2) The purposes for the possession of marijuana were not solely for palliative or therapeutic use by the individual with a serious or debilitating medical condition who raised the defense.
(c) An individual is not required to possess a registry identification card to raise the affirmative defense set forth in this section.
(d) If an individual demonstrates the individual's medical purpose for using marijuana pursuant to this section, except as provided in § 4909A of this title, the individual shall not be subject to the following for the individual's use of marijuana for medical purposes:
(1) Disciplinary action by an occupational or professional licensing board or bureau; or
(2) Forfeiture of any interest in or right to nonmarijuana, licit property.
(e) (1) This section shall only apply for arrests made after July 1, 2011, until 75 days after registration for qualified patients is available, and
(2) Thereafter, for arrests made after a valid an application for a qualifying patient has been submitted and before the registry identification card has been received.
