Hawaii has one of the oldest medical cannabis laws in the country, passed by the legislature in 2000. Most of what Hawaii patients feel in 2026 comes from two laws passed in 2025, Act 46 and Act 241, whose effects are rolling out across this year and into 2028. The 2026 session considered proposals but passed no major new medical law.

This post explains the 2025 acts that shape 2026, what changed for caregivers and home growers, what the telehealth rule means for getting certified and what is scheduled for 2028. It is program and access information only.

Hawaii’s program in brief

Item	Hawaii status
Regulator	Department of Health, Medical Cannabis Registry Program
Patient card	Yes, through the registry
Licensed dispensaries	Yes, statewide
Patient home grow	Allowed, within an adequate supply
Caregivers	Up to five patients under Act 46
Out of state patients	Registry option for visitors
Adult use	Not legal

Act 46: caregivers and enforcement

Act 46 of 2025 made three changes that matter in 2026.

First, a registered primary caregiver may now care for up to five qualifying patients at a time. Before, a caregiver could generally care for only one patient, with an exception for parents of more than one minor patient.

Second, Act 46 repealed the ban on caregivers cultivating for their patients, retroactive to January 1 2025. Caregivers may cultivate an amount not exceeding an adequate supply for each patient, and each grow location may serve no more than five patients.

Third, the Department of Health gained authority to impose administrative penalties, issue cease and desist orders and take enforcement action for violations. Penalties become final twenty days after notice unless a contested case hearing is requested.

Act 241: telehealth, fees and dispensary rules

Act 241 of 2025 is broader. It lets a provider establish the provider patient relationship by telehealth for the purpose of a written certification. It caps the fees providers may charge for certification. It allows hemp products and accessories to be sold at retail dispensing locations, though not in waiting rooms. It clarifies transport rules for sales between dispensaries.

The act also created criminal penalties for running an unlicensed dispensary and funded the Attorney General’s Drug Nuisance Abatement Unit to address illegal cannabis and hemp operations.

The 2028 cultivation change

The part of Act 241 most likely to affect home growers starts January 1 2028. From that date, cultivating cannabis without a cannabis cultivator license issued by the Department of Health is prohibited. How that interacts with patient and caregiver grow rights depends on rules the department has not finished. If you grow under your registry card today, follow the department’s notices closely through 2027.

Bills from the 2026 session

Two 2026 bills drew notice. HB 600 dealt with registration details for patients and caregivers. HB 1542 would have allowed patients with certain conditions to use medical cannabis inside specified health care facilities, with smoking and vaping prohibited there. Neither was enacted in the 2026 session. HB 1542 died in the House Consumer Protection and Commerce Committee when the session ended.

Adult use proposals also failed again. HB 1246, carried over from 2025, did not advance before a 2026 deadline.

Getting certified in 2026

Find a physician or advanced practice registered nurse who issues written certifications. Under Act 241 this can happen over telehealth, and the fee is capped by law. Apply through the Department of Health registry online, upload your certification and pay the registry fee. Renew before your card expires, since gaps can affect a caregiver’s ability to grow for you.

For caregivers who grow

Register with the Department of Health. Keep each grow location at or under five patients. Keep records showing which plants belong to which patient. Keep the grow enclosed and out of public view. Expect inspections now that the department has penalty authority.

Visitors

Hawaii offers a registry path for out of state patients who hold a valid card from their home state. Visitors can buy at licensed dispensaries but cannot grow. Flying between islands with cannabis is a federal airspace issue, so check rules before inter island travel.

How Hawaii compares in 2026

State	Caregiver patient limit	Telehealth certification	Adult use
Hawaii	Five	Yes, under Act 241	No
California	Varies by county	Yes	Yes

Hawaii remains a medical only state, which makes the registry the one legal route for residents.

Registry costs and timing

The Department of Health sets the registry fee and posts it on the registry site, so check the current amount before you apply. Provider fees for certification are capped under Act 241, which helps patients compare offers. Processing time varies with volume, so apply well before an old card expires. Caregivers should renew on the same cycle as their patients, since a lapse on either side can interrupt a legal grow.

Common mistakes to avoid

Do not assume a caregiver can add a sixth patient at a second address. The five patient limit applies per caregiver and per grow location. Do not buy from storefronts that are not on the department’s licensed list, since Act 241 created criminal penalties for unlicensed dispensaries. Do not carry products to the mainland or across federal property. Keep your registry card and the product label together whenever you travel on island.

Program access, age and the law

This guide covers how the Hawaii program works and who can access it. It does not describe what cannabis does for any condition, and it is not a substitute for a conversation with a licensed practitioner. Rules can change after a legislative session or a new agency rule, so confirm every detail with the Hawaii Department of Health Medical Cannabis Registry Program before you act. Federal law still treats cannabis outside a state medical license as a controlled substance, and seeds have their own federal rules, so read our December 11 2026 seed rule explainer before ordering. Kind Seed Co sells only to adults 21 and older, and buying seeds is never a substitute for following the home grow rules in your state.
