Hawaii Cannabis Laws Explained

Act 241, signed into law in June 2025 and effective July 1 of that year, eliminated Hawaii’s list of specific qualifying medical conditions — the single biggest expansion of the state’s medical cannabis program since it was created in 2000. Any condition now qualifies if a physician or advanced practice registered nurse determines cannabis may benefit the patient. That shift, along with telehealth certification and a caregiver expansion, has reshaped what it means to access medical cannabis in Hawaii. But recreational use remains illegal, and the political logjam in the House shows no sign of breaking before the November 2026 election.

Here is how Hawaii’s cannabis laws break down right now, what changed in the 2025 session, and what travelers need to know before they pack.

Hawaii’s Medical Cannabis Program: What Changed in 2025

$38.50 a year — that is what a Hawaii medical cannabis card costs. The bigger expense is the physician certification, which typically runs $200–400 depending on the provider. Since July 2025, getting that certification has become simpler: Act 241 (HB 302) removed the requirement that a patient have a specific condition from a state-approved list. Now any medical condition qualifies, as long as a Hawaii-licensed physician or APRN with an established relationship with the patient determines cannabis may help. The same law also made telehealth certifications permanent, so initial consultations no longer require an in-person visit.

Registered patients can possess up to 4 ounces of usable cannabis (flower, concentrates, and edibles combined — not 4 ounces of flower plus additional product). Purchase limits allow up to 4 ounces per 15-day rolling period, or 8 ounces per 30 days. Home cultivation is permitted: up to 10 plants total (7 immature, 3 mature), each with an identification tag, at a location registered with the state.

Act 046 (SB 1429), also signed in 2025, expanded caregiver allowances. A single caregiver can now serve up to 5 patients (up from 1), with a maximum of 5 registered grow sites per location. The same law retroactively restored patient cultivation rights that had sunset at the end of 2024. Violations carry fines up to $5,000 per infraction.

Dispensaries operate on Oahu, Hawaii Island, Maui, and Kauai — roughly eight licensed locations statewide as of 2026. Product selection includes flower, concentrates, edibles, and topicals, with flower priced around $15–20 per gram. Dispensaries accept cash or debit only — federal banking restrictions block credit cards. The state tracks all purchases through a seed-to-sale monitoring system.

Recreational Cannabis: Stalled in the House

The Hawaii Senate has passed a cannabis legalization bill every year since 2022, often with bipartisan margins. The House of Representatives has killed every single one. That pattern — Senate advances, House blocks — is the central political fact of cannabis reform in Hawaii as of 2026.

House Speaker Nadine Nakamura publicly declared legalization “effectively dead” for the 2026 session. A 300-page comprehensive bill (HB 1246) cleared two House committees in 2025 — the furthest any legalization measure has advanced in that chamber — before a rare motion to recommit killed it on the floor. Companion legislation on the Senate side (SB 1613) stalled in committee by the legislative deadline.

Multiple alternative approaches failed in 2026: a low-dose bill capping THC at 5 mg per serving (SB 3275), a federal-contingent bill tying legalization to DEA rescheduling (SB 2421), and a ballot-measure proposal from Rep. David Tarnas that would have bypassed House leadership entirely. None advanced.

The disconnect between public opinion and legislative action is stark. A 2023 poll found 58% of Hawaii adults favor legalizing recreational cannabis. A January 2026 state report projected a regulated market would generate $46–90 million in monthly sales by year five. The Hawaii Cannabis Industry Association estimates $82 million in annual tax revenue and 3,375 new jobs. Under the proposed framework, adult-use cannabis would carry a 14% excise tax plus 4% GET; medical cannabis would remain at 4% GET.

Possession Limits, Penalties, and Decriminalization

Three grams or less: a $130 fine, no jail, no criminal record. That is the decriminalization threshold Hawaii enacted in 2019. Above that, penalties escalate fast.

More than 3 grams but less than 1 ounce is a petty misdemeanor carrying up to 30 days in jail and a fine up to $1,000. One ounce to 1 pound is a misdemeanor — up to one year and $2,000. One pound or more is a Class C felony, with up to five years in prison and a $10,000 fine. Cultivation without a medical registration is a Class C felony regardless of plant count. Sale or distribution is a Class B felony, up to 10 years.

Medical patients are not exempt from public consumption restrictions. Cannabis use is prohibited in public places, workplaces, school properties, and moving vehicles. Dispensaries cannot allow consumption on their premises. Driving under the influence of cannabis is illegal for everyone, medical card or not.

HB 132, signed into law in 2025, streamlined the expungement process for past cannabis convictions involving conduct that is now legal or decriminalized. It builds on a 2024 pilot program in Hawaii County that cleared 1,321 records automatically. The new law removes a distinction between marijuana and other Schedule V drugs for expungement purposes, reducing the administrative burden of manually combing through records.

Can Visitors Buy Cannabis in Hawaii?

If you are visiting Hawaii with an out-of-state medical card, that card alone gets you nothing. Hawaii does not recognize any other state’s medical cannabis registration. But eligible visitors can apply for a temporary 329V card through the Hawaii Department of Health.

The temporary card costs $49.50, lasts up to 60 days, and can be renewed once for a total of 120 days per calendar year. You will need a valid government-issued medical cannabis card from your home state or territory, plus identification. The application does not authorize home cultivation. Once approved, you can purchase from licensed dispensaries just like a resident patient.

Do not bring cannabis into Hawaii. The Department of Health explicitly advises against it — any trip to or from Hawaii passes through federal jurisdiction, exposing travelers to potential arrest or delays at the airport. TSA may refer cannabis discoveries to local law enforcement. Inter-island commercial flights also fall under federal authority, so carrying cannabis between islands is risky even for registered patients.

Hemp, Delta-8, and the Legal Gray Zone

What about delta-8, delta-10, and the hemp-derived THC products sold in shops around Waikiki? The short answer: it is complicated, and the risk is yours to carry.

Delta-8 THC exists in a legal gray area. Federal law allows hemp-derived delta-8 as long as the delta-9 THC content is below 0.3%. Hawaii has not passed specific regulations addressing delta-8, so its status is ambiguous. Many retailers sell it; law enforcement interpretation varies by county. Delta-10 follows the same pattern — no state rules, uncertain enforcement.

What Hawaii has clearly regulated are hemp products. Retail sales of hemp flower, leaf material, and pre-rolls are prohibited regardless of labeled THC or THCA content. Hemp vapes are also banned. Artificially derived or synthetic cannabinoids — including converted delta-8 commonly used in commercial products — cannot be sold in manufactured hemp products.

Compliant hemp products can contain small amounts of naturally occurring THC, but with strict limits: gummies may contain no more than 1 mg of total THC per serving and 5 mg per container. Beverages are capped at 0.5 mg per container. All products must meet concentration, testing, packaging, and labeling requirements. A state registration system for hemp retailers and distributors took effect January 2026, with enforcement beginning July 1.

The bottom line: delta-9 THC is strictly controlled under the medical program. Anything sold outside a licensed dispensary carries legal risk, and law enforcement may not distinguish between THC variants during an arrest.

Getting a Medical Card: Costs and Process

Getting a Hawaii medical cannabis card involves two steps and two separate costs. First, obtain a written certification from a Hawaii-licensed physician or APRN with whom you have an established treatment relationship. Telehealth appointments satisfy this requirement since 2020. Physician consultation fees typically range from $200 to $400.

Second, submit that certification along with your application to the Hawaii Department of Health’s medical cannabis registry. The state registration fee is $38.50. Once approved, you receive a 329 card valid for one year. Renewal follows the same process — updated physician certification plus another $38.50 — and must be completed before the current card expires. Digital cards are accepted at dispensaries, so there is no gap between approval and access.

Patients receiving hospice care may be certified by a licensed hospice provider. The 2025 expansion via Act 241 means virtually anyone with a medical condition and a willing provider can qualify — the old list of specific conditions (cancer, glaucoma, PTSD, Crohn’s, etc.) is no longer a barrier.

Before You Go: Hawaii Cannabis Questions

Can I use my out-of-state medical card in Hawaii?

No. Hawaii does not recognize any other state’s medical cannabis card. You can apply for a temporary 329V registration ($49.50, up to 60 days) if you hold a valid medical card from your home state. Apply before your trip so you can visit a dispensary once approved.

How much cannabis can I possess as a registered patient?

Four ounces of usable cannabis — that includes flower, concentrates, and edibles combined, not 4 ounces of flower plus extra product. Purchase limits allow up to 4 ounces per 15-day rolling period. The state tracks all purchases through a seed-to-sale system.

What happens if I am caught with cannabis at the airport?

TSA operates under federal law, which still classifies cannabis as a Schedule I substance. They may refer discoveries to local law enforcement. Even with a valid Hawaii medical card, transporting cannabis through an airport involves federal jurisdiction. The Department of Health advises against it.

Is delta-8 legal in Hawaii?

Delta-8 exists in a legal gray area. Hawaii has not passed specific regulations addressing it, but the state has banned hemp flower, pre-rolls, and vapes, and prohibits artificially derived cannabinoids. Law enforcement interpretation varies. Buying delta-8 from an unregulated shop carries real legal risk.

When might recreational cannabis become legal in Hawaii?

Not before the November 2026 election at the earliest. All House seats and half of Senate seats are on the ballot. The House has been the sole obstacle for four consecutive years. If the election shifts the House toward pro-legalization members, a bill could reach Governor Green’s desk in 2027.

The Bottom Line on Hawaii Cannabis Laws

Hawaii’s medical program is one of the most accessible in the country since the 2025 reforms — any condition qualifies, telehealth is standard, and caregivers can serve multiple patients. But the political bottleneck in the House of Representatives means recreational legalization remains out of reach despite strong Senate support, a supportive governor, and clear public backing. For now, the only legal path to cannabis in Hawaii runs through the medical program, and that path is open to residents and visitors alike — as long as you follow the rules.
