Medical Cannabis
HRS 329-122 — a certification, an adequate supply of ten plants and four ounces, and never in public or in a moving vehicle
A qualifying patient eighteen years of age or older may use cannabis medically where the certifying physician, advanced practice registered nurse or hospice provider has explained the potential risks and benefits and documented that the patient understands them, and the patient holds no more than an adequate supply.
Who handles this in Hawaii: Hawaii State Bar Association, Lawyer Referral and Information Service; and legal aid programs and the state offices, listed in the Hawaii directory.
- An adequate supply, jointly between the patient and the primary caregiver, is no more than ten cannabis plants and four ounces of usable cannabis at any given time.
- A qualifying patient is one certified in writing for a debilitating medical condition, certified by the primary treating provider for another condition, or receiving hospice care.
- A patient under eighteen also needs a parent or guardian's written consent, and that person serves as the primary caregiver.
- A patient from another state, territory or the District of Columbia registers with the department of health, with their card and photo identification from the same place, and receives a registry card.
Where it is not covered. Medical use is not authorized in a school bus, public bus or any moving vehicle; in one's workplace; on school grounds; at a public park, beach or recreation center; at any other place open to the public; or where it endangers someone else. Transporting it through a public place is allowed in a sealed container, out of public view, and unopened.
