Hawaii medical cannabis rules: what to know and how to check

Hawaii allows medical cannabis only. To buy it, you need a certification from a Hawaii doctor or APRN and a 329 registry card from the Department of Health (DOH). Visitors with a card from their home state can apply for a temporary Hawaii card. You can buy only in person at a licensed dispensary. Check it on DOH’s list before you buy.

What’s different in Hawaii

Hawaii allows medical cannabis only. There is no legal adult-use (recreational) market. Having any cannabis without a medical registration is still a crime. Having 3 grams or less is a violation with a $130 fine. A 2026 bill to set up adult-use sales was deferred in committee.

To use medical cannabis, you need a written certification from a Hawaii doctor or advanced practice registered nurse (APRN) and a registry card from the Department of Health, called a "329 card." You are not covered until you have the card. Carry the card and a valid photo ID whenever you have medical cannabis.

Visitors who hold a medical cannabis card from their home state or territory can apply for a temporary Hawaii 329 card. It lasts up to 60 days and can be renewed once a year. Visitors may buy only at licensed dispensaries and may not grow.

The Department of Health's Office of Medical Cannabis Control and Regulation (OMCCR) licenses dispensaries and oversees the labs that test their products. Licensed dispensaries are on Hawaii Island, Maui, Oahu and Kauai. Dispensaries can't deliver. You may not carry cannabis between islands.

Medical use is not allowed in any moving vehicle, at work, on school grounds, at public parks and beaches, or in any other place open to the public. Don't drive after using cannabis.

Hemp products are different. Hemp flower, vapes and foods with cannabinoids can't be sold in Hawaii. Allowed hemp products have very low THC limits.

Hawaii recalls

We did not find a public recall list on OMCCR’s website. State rules say each dispensary must have a written recall plan, warn patients and the public about a hazard when needed, and tell DOH within 24 hours of starting a recall. 5 CHSA does not monitor Hawaii recalls yet. If you think a product made you sick, call Poison Help, then tell OMCCR.
