Summary
Hawaii allows registered medical cannabis patients to grow up to ten plants at one secured location under HRS 329-122. As of December 31, 2024, primary caregivers may no longer cultivate. Recreational cultivation remains illegal statewide.
(a) A qualifying patient shall obtain medical cannabis or manufactured cannabis products only: (1) From a dispensary licensed pursuant to chapter 329D; provided that the cannabis shall be purchased and paid for at the time of purchase; (2) By cultivating cannabis in an amount that does not exceed an adequate supply for the qualifying patient pursuant to section 329-122; provided that each location used to cultivate cannabis shall be used to cultivate cannabis for not more than five qualifying patients; or (3) From the qualifying patient's primary caregiver who cultivates cannabis in an amount that does not exceed an adequate supply for the qualifying patient pursuant to section 329-122; provided that each location used to cultivate cannabis shall be used to cultivate cannabis for not more than five qualifying patients.
Full Breakdown
Under HRS 329-122, a registered qualifying patient may cultivate an 'adequate supply' of cannabis, no more than ten plants (mature or immature), at one designated grow site that must be enclosed, locked, and not visible to the public. No more than five patients may share a single grow site. Since December 31, 2024, primary caregivers are no longer authorized to cultivate cannabis for patients. Recreational home cultivation is prohibited; Hawaii has not legalized adult-use cannabis, and only state-licensed dispensaries may produce cannabis for the medical program. Counties cannot expand cultivation rights. Exceeding the limit or growing without registration is a criminal offense.
Violations & Penalties
Exceeding ten plants or unregistered cultivation is a misdemeanor or felony under HRS 712, with penalties including jail and fines based on plant count.
