Is weed legal in Hawaii?

Recreational status

Recreational cannabis is not legal in Hawaii. (Dual Use of Cannabis Task Force)

The cited page describes a legislatively convened task force to explore adult-use legalization and its impacts on medical patients; it does not describe an adult-use law in force. No registered source states that an adult-use law has since been enacted.

A task force studies the question; it does not change the law, and nothing it recommends reaches a counter until the legislature acts. Until then a card is the only lawful way into cannabis here.

Medical status

A full medical cannabis program runs in Hawaii, serving patients the program registers. (HRS Chapter 329, Part IX: Medical Use of Cannabis (§§329-121 to 329-131))

HRS 329-121 defines a broad set of debilitating medical conditions -- including cancer, glaucoma, lupus, epilepsy, multiple sclerosis, and HIV/AIDS, or any chronic condition producing cachexia, severe pain, severe nausea, seizures, or severe muscle spasms, plus any other condition the department of health approves -- and defines 'usable cannabis' as the dried leaves and flowers of the plant, not a low-THC or CBD-only preparation, so this is recorded as comprehensive.

A card here opens two supply routes instead of one, a dispensary counter and a patient's own plants, and a single possession ceiling covers both. The Office of Medical Cannabis Control and Regulation runs the register and licenses the dispensaries.

Hemp-derived products

Hawaii permits the sale of hemp-derived products and limits which ones. (Hawaii Administrative Rules Chapter 11-37: Hemp Processing and Manufactured Hemp Products (Interim Rules))

Allowed manufactured hemp products are limited to edible types specified elsewhere in the chapter and to forms for topical application to the skin or hair, under HAR 11-37-4(c), and the chapter separately bars a list of ingredients and any product designed to resemble candy or appeal to children.

Hawaii writes this rule as a list of allowed forms rather than a list of banned ones, so a product missing from the list is out by default. A separate part of the chapter reaches how a product looks and not only what is in it.

Home cultivation

Hawaii allows a registered patient to grow up to 10 plants at home, and nobody else. (HRS Chapter 329, Part IX: Medical Use of Cannabis (§§329-121 to 329-131))

HRS 329-130(a)(2) authorises a qualifying patient to obtain cannabis by cultivating an amount not exceeding an adequate supply, and HRS 329-121 caps an adequate supply at ten cannabis plants, whether immature or mature, and four ounces of usable cannabis. Each location used to cultivate may be used by no more than five qualifying patients, and after December 31, 2023 no primary caregiver is authorised to cultivate.

The count belongs to the site as much as to you: one registered location can serve up to five patients and no more. A caregiver may no longer do the growing on a patient's behalf, so the plants are the patient's own job now.

Possession and purchase limits

The possession limit, as Hawaii states it: An adequate supply: not more than ten cannabis plants, whether immature or mature, and four ounces of usable cannabis at any given time, jointly possessed by the qualifying patient and the primary caregiver. (HRS Chapter 329, Part IX: Medical Use of Cannabis (§§329-121 to 329-131))

This is the statutory possession ceiling ('adequate supply') defined at HRS 329-121; it is not a statement that a patient may cultivate those plants, which is recorded separately as pending.

On buying, Hawaii states: Not more than four ounces of cannabis dispensed to a person during any period of fifteen consecutive days, and not more than eight ounces during any period of thirty consecutive days. (Hawaii Administrative Rules Chapter 11-850: Medical Cannabis Dispensaries)

The possession figure is shared with your caregiver rather than doubled by having one. Two buying clocks run at the same time, so four ounces taken in a fortnight leaves four for the rest of the month.

Minimum age

There is no recreational channel in Hawaii, so no recreational age applies. (Dual Use of Cannabis Task Force)

Null because no adult-use law is in force in Hawaii.

You must be 18 or over to hold a card and buy for yourself. (HRS Chapter 329, Part IX: Medical Use of Cannabis (§§329-121 to 329-131))

HRS 329-122(b) treats a qualifying patient under eighteen as a distinct case: a parent, guardian, or person with legal custody must consent in writing and control the acquisition, dosage, and frequency of the patient's medical use. HAR 11-850-33(d)(3), also registered for this question, independently bars a dispensary from dispensing directly to a qualifying patient under eighteen.

Below eighteen a dispensary hands nothing to the patient directly, so the counter transaction belongs to the adult standing there. That adult signs a written consent and keeps control of the amount and the frequency.

Where you can buy

You can buy lawfully from a licensed medical dispensary. (HRS Chapter 329, Part IX: Medical Use of Cannabis (§§329-121 to 329-131))

HRS 329-130(a) also lets a qualifying patient obtain medical cannabis by cultivating it personally in lieu of a dispensary purchase; that is not a purchase channel and is not counted here, and whether it is permitted is recorded separately as pending under home_cultivation.

The plant allowance is a supply route and not a purchase, so what you grow counts against what you may hold rather than against your dispensary clock. Every purchase itself goes through a dispensary the Department of Health licenses.

The Hawaii store list names every licensed location this site holds a record for.

Federal law applies here too, and it is not the same. Read what federal law says about weed.
