No, weed is not recreational in Hawaii. Possessing marijuana without a medical cannabis card is still against the law, though Hawaii decriminalized small amounts in 2020: three grams or less is a civil violation with a flat $130 fine and no criminal record. Anything above that, and any sale, sharing, or home growing without a medical card, remains a criminal offense.
Legalization Bills Keep Failing
Hawaii lawmakers have tried repeatedly to open an adult-use market and haven’t succeeded. In the 2025 session, House Bill 1246 proposed legalizing personal marijuana use for adults 21 and older and setting up a regulator inside the Department of Commerce and Consumer Affairs. Its Senate companion, SB 1613, never got a hearing. Neither bill made it through.
The 2026 session brought SB 2421, which would have created a cannabis oversight office triggered only by a change in federal law or a state constitutional amendment, and SB 3275, which would have let adults buy and possess limited amounts of low-THC cannabis. Both stalled after key House lawmakers said the votes weren’t there. A separate bill (SB 319) to raise the decriminalized amount from three grams to 15 grams was carried over to the next session without a vote.1BillTrack50. HI SB319 – Relating to Marijuana Governor Josh Green has said he would sign a legalization bill, but nothing has reached his desk.
What the $130 Fine Actually Covers
Since January 2020, possessing three grams or less of marijuana in Hawaii is a violation rather than a crime. That sits below even a petty misdemeanor on the state’s offense ladder. You pay a flat $130 fine. No arrest, no jail, no criminal record.2Justia Law. Hawaii Code 712-1249 – Promoting a Detrimental Drug in the Third Degree
Three grams is roughly enough for a couple of joints, so the shield is narrow. Decriminalization is not legalization. You still can’t legally buy recreational cannabis from any store, you can’t grow at home without a medical card, and being over the three-gram line drops you into criminal territory quickly.
Penalties Once You Cross Three Grams
The penalty scale steps up sharply by weight:
- More than 3 grams but less than one ounce: petty misdemeanor, up to 30 days in jail and a fine up to $1,000.2Justia Law. Hawaii Code 712-1249 – Promoting a Detrimental Drug in the Third Degree
- One ounce or more but less than one pound: misdemeanor, up to one year in jail and a fine up to $2,000.3Justia Law. Hawaii Code 712-1248 – Promoting a Detrimental Drug in the Second Degree
- One pound or more: Class C felony, up to five years in prison and a $10,000 fine.4Justia Law. Hawaii Code 712-1247 – Promoting a Detrimental Drug in the First Degree
- Two pounds or more: Class B felony, up to 10 years in prison and a $25,000 fine.5Justia Law. Hawaii Code 712-1249.5 – Commercial Promotion of Marijuana in the Second Degree
The jump from a violation to a petty misdemeanor happens just past three grams. The difference between a $130 ticket and a possible month in jail is roughly the weight of a penny.
Sharing, Selling, and Growing
Giving marijuana to a friend is not treated the same as keeping it for yourself. Distributing any amount for free is a misdemeanor, up to one year in jail and a $2,000 fine.3Justia Law. Hawaii Code 712-1248 – Promoting a Detrimental Drug in the Second Degree Selling or bartering any amount, no matter how small, is automatically a Class C felony.4Justia Law. Hawaii Code 712-1247 – Promoting a Detrimental Drug in the First Degree Distributing an ounce or more is also a Class C felony. Selling to a minor is a Class B felony regardless of quantity.5Justia Law. Hawaii Code 712-1249.5 – Commercial Promotion of Marijuana in the Second Degree
Home growing without a medical card is a felony once you hit 25 plants (Class C, up to five years and $10,000). At 50 or more plants, it becomes a Class B felony carrying up to 10 years and a $25,000 fine. Growing on someone else’s land without permission is a Class B felony no matter how many plants are involved.5Justia Law. Hawaii Code 712-1249.5 – Commercial Promotion of Marijuana in the Second Degree
Driving After Using
Driving impaired by marijuana is prosecuted the same way as drunk driving under HRS 291E-61, which covers operating a vehicle under the influence of any drug in Schedules I through IV. A conviction requires proof that the drug impaired your ability to drive safely.6Justia Law. Hawaii Code 291E-61 – Operating a Vehicle Under the Influence of an Intoxicant
A first offense with no prior conviction in the past ten years carries license revocation of at least one year and up to 18 months, with a mandatory ignition interlock. Criminal penalties run from a $250 to $1,000 fine, or 48 hours to five days in jail, or 72 hours of community service, plus a 14-hour substance abuse program. Repeat offenses within ten years bring longer jail terms, larger fines, and eventually vehicle forfeiture. A passenger under 15 in the car adds a mandatory 48-hour jail sentence.6Justia Law.

The Only Legal Path: A Medical Card
Hawaii’s medical cannabis program, established in 2000, is the only legal way to buy, possess larger amounts of, or grow marijuana in the state.7PubMed Central. Hawaii First to Pass Medical Marijuana Bill You need certification from a Hawaii-licensed physician or Advanced Practice Registered Nurse confirming a qualifying condition, then you apply through the Department of Health’s Medical Cannabis Registry. Fees run $38.50 for one year or $77 for two.8Hawaii Department of Health. In-State Patient Application A 2025 law (HB 302) broadened physician discretion and allowed the provider-patient relationship to be established through telehealth.9LegiScan. Hawaii HB302 – Relating to Cannabis
Once approved, patients receive a 329 Card and can possess up to four ounces of usable cannabis and grow up to ten plants (immature or mature). Plants must be in a secure, enclosed location not visible to the public.10Justia Law. Hawaii Code 329-121 – Definitions
Visiting From Another State
If you hold a valid medical cannabis card from another U.S. state, territory, or DC, you can apply online for a 60-day out-of-state registration for a $49.50 non-refundable fee, up to twice per calendar year. Visitors can possess up to four ounces but cannot grow plants, and your home-state condition must qualify under Hawaii law. A physician’s recommendation alone is not enough — you need an actual government-issued card.11Hawaii Department of Health. Out-of-State Patient Application Not every island has a dispensary, and the fee doesn’t come back if your island has no supply. International visitors have no registration path.
Federal Law Still Bites in Hawaii
Marijuana remains a Schedule I substance under federal law.12Office of the Law Revision Counsel. 21 US Code 812 – Schedules of Controlled Substances A December 2025 executive order directed the Attorney General to complete rulemaking to reschedule it to Schedule III, but as of early 2026 that process is still pending, and even a rescheduling would not legalize recreational use.13The White House. Increasing Medical Marijuana and Cannabidiol Research
Federal law matters in Hawaii more than in most states because moving between islands or off the islands puts you in federal jurisdiction. The TSA does not specifically search for marijuana, but if screeners find it they are required to refer the matter to law enforcement.14Transportation Security Administration. Medical Marijuana The Hawaii Department of Health warns medical patients directly that inter-island or mainland travel by any means may result in delay or arrest.11Hawaii Department of Health. Out-of-State Patient Application Federal law also governs military bases, national parks, and federal buildings across the state.
Two more federal traps are worth knowing. First, firearms: federal law bars any “unlawful user of” a controlled substance from possessing a gun or ammunition, and because marijuana is still Schedule I, that includes Hawaii medical card holders. Violation is a federal felony, and a 329 Card creates no exception.15Office of the Law Revision Counsel. 18 US Code 922 – Unlawful Acts Second, employment: federal contractors and grantees must maintain drug-free workplaces under the Drug-Free Workplace Act of 1988,16U.S. Department of Labor. Drug-Free Workplace Regulatory Requirements and given Hawaii’s federal and military footprint, that covers a lot of workers. DOT-regulated roles (pilots, truck and bus drivers, ship captains, train engineers, aircraft mechanics) remain barred from marijuana use even as rescheduling moves forward.17Drug and Alcohol Clearinghouse.
