Restricted. Hemp-derived delta-9 edibles and tinctures can be sold at Hawaii retail, but only inside narrow per-serving and per-container caps set by HAR Chapter 11-37 as amended December 6, 2024. Gummies and similar solid edibles are capped at 1 mg total THC per serving and 5 mg per container. Oil-based tinctures are capped at 2.5 mg per serving and 75 mg per container. Beverages are capped at 0.5 mg per container. Inhalable hemp products are prohibited outright under HRS Section 328G-3. Most hemp-derived delta-9 SKUs sold in other states exceed these caps and cannot lawfully ship into Hawaii.

HRS Chapter 328G (Section 328G-3); HAR Chapter 11-37 (amended Dec 6, 2024); Act 263 (HB 1359, 2023); Act 269 (2025) retailer registration
Edibles (gummies, tablets, capsules, powders, softgels, gelcaps): 1 mg total THC per serving, 5 mg per container. Oil-based tinctures: 2.5 mg per serving, 75 mg per container (2 fl. oz. max). Beverages: 0.5 mg per container (6 to 12 fl. oz.). Inhalable hemp products prohibited.
Yes
Hawaii has a medical cannabis patient registry under HRS Chapter 329 and a licensed medical cannabis dispensary system under HRS Chapter 329D. The state has not legalized adult-use cannabis. Manufactured hemp products are regulated separately by the Department of Health under HRS Chapter 328G and HAR Chapter 11-37. Act 263 (HB 1359, 2023) reorganized hemp production rules and became law without Governor Green's signature on July 11, 2023. The DOH interim rules at HAR 11-37 were first effective August 8, 2023; the December 6, 2024 amendments added the current edible, tincture, and beverage potency caps.
Hemp-derived delta-9 is chemically identical to marijuana-derived delta-9. The legal distinction is the source plant: hemp is Cannabis sativa with delta-9 THC at or below 0.3 percent by dry weight at harvest. State delta-9 frameworks for hemp key off either that federal standard, a total-THC formula, or per-serving and per-container mg caps. Hawaii uses the caps approach.
HRS Section 328G-3 governs hemp processing, hemp product sale, and labeling. The December 2024 amendments to HAR 11-37 set the current potency ceilings. Gummies, tablets, capsules, powders, softgels, and gelcaps are capped at 1 mg total THC per serving and 5 mg per container. Oil-based tinctures are capped at 2.5 mg per serving and 75 mg per container, with a 2 fl. oz. container maximum. Beverages are capped at 0.5 mg per container in 6 to 12 fl. oz. sizes. These are total-THC caps measured after post-decarboxylation testing, so any THCA content counts toward the limit.
HRS Section 328G-3 separately prohibits the sale, distribution, or holding for sale of any cannabinoid product designed to be aerosolized for respiratory delivery. That removes delta-9 vapes, cartridges, and inhalers from the lawful retail mix regardless of mg content. Foods containing added cannabinoids are also restricted, with a narrow exception for hemp ingredients FDA has recognized as generally recognized as safe.
Hawaii's caps are among the lowest in the country. Most hemp-derived delta-9 gummies sold in other states run 5 mg or 10 mg per serving and 50 mg to 100 mg per container. Those products cannot lawfully be sold at Hawaii retail or shipped to Hawaii consumers.
The Department of Health enforces HAR 11-37 through the Office of Medical Cannabis Control and Regulation. HRS Section 328G-3 authorizes penalties up to 10,000 dollars per offense plus product removal. Act 269 (2025) added a retailer and distributor registration requirement administered by OMCCR. The registration window opened January 1, 2026 with a 50 dollar fee covering five years, and active enforcement began no earlier than February 1, 2026. Online sellers shipping into Hawaii fall within scope.
Compliant hemp-derived delta-9 edibles, tinctures, and low-dose beverages can be sold by registered Hawaii retailers within the HAR 11-37 caps. The mg-per-container ceilings are low enough that a single Hawaii-compliant gummy package contains less THC than a single serving of many mainland products. Hemp-derived delta-9 produces the same effects and the same metabolites as marijuana-derived delta-9 and will trigger a positive on standard urine, saliva, and hair drug screens.
The biggest near-term shift is federal. H.R. 5371 Section 781, signed November 12, 2025, replaces the 2018 Farm Bill delta-9-only standard with a post-decarboxylation total-THC test and caps finished hemp products at 0.4 mg total THC per container. The provision takes effect November 12, 2026. The 0.4 mg per container ceiling is lower than Hawaii's 5 mg gummy container cap and 75 mg tincture cap, so Hawaii operators will need to reformulate again at the federal compliance date.

Is hemp-derived delta-9 THC legal in Hawaii in 2026?
Yes, but only within the HAR 11-37 caps: 1 mg per serving and 5 mg per container for solid edibles, 2.5 mg and 75 mg for tinctures, 0.5 mg per container for beverages. Inhalable products are prohibited.
What is the difference between hemp delta-9 and marijuana delta-9?
Chemically they are the same molecule. The legal distinction is the source plant. Hemp must meet the 0.3 percent delta-9 threshold by dry weight at harvest under federal law.
Does hemp-derived delta-9 show up on a drug test?
Yes. Hemp delta-9 produces the same metabolites as marijuana delta-9.
Can I order hemp delta-9 edibles or beverages online to Hawaii?
Yes if the seller is registered with OMCCR under Act 269 and the product complies with HAR 11-37 caps. Non-compliant shipments are subject to seizure.
How does delta-9 compare to THCA in Hawaii?
THCA is captured by the post-decarboxylation total-THC reading and is effectively unavailable as flower. Compliant low-dose delta-9 edibles can be sold. See our Hawaii THCA page.
What changes November 12, 2026?
H.R. 5371 Section 781 takes effect with a 0.4 mg total THC per container federal ceiling that is tighter than Hawaii's existing caps for several product categories.
