The legality of HHC falls in line with federal law regarding hemp-derived compounds, similar to delta 8, thus making it likely legal for sale and consumption.
Rhode Island	Likely legal	In Rhode Island, the legality of HHC is uncertain as state laws do not specifically address its status. However, given the state's prohibition of THCs and synthetic substances with similar chemical structures and pharmacological activities could potentially be considered illegal.
Wyoming	Likely legal	In Wyoming, the legality of HHC remains unaddressed by specific laws. However, under the 2018 Farm Bill, naturally occurring hemp-derived HHC is legal alongside hemp-derived CBD products with less than 0.3% delta 9 THC.
Illinois	Gray Area	In Illinois, while the HHC flower is legal, the broader regulatory status of HHC remains unaddressed by state law. Lawmakers are actively considering regulations on intoxicating cannabinoids derived from hemp, including HHC, alongside delta 8 THC. Illinois legalized hemp in 2018 under the Industrial Hemp Act, allowing products with less than 0.3% delta 9 THC in line with federal regulations.
Kentucky	Gray Area	HHC is currently legal in Kentucky, but pending legislation may change its status as the state considers banning HHC and other intoxicating hemp cannabinoids. The temporary injunction allows its sale until formal rulemaking occurs, reflecting ongoing regulatory scrutiny by the state Senate.
Texas	Gray Area	In Texas, the legality of HHC is currently uncertain amid ongoing legislative discussions regarding hemp-derived compounds like delta 8. While HHC-O is presently legal, potential changes in delta 8 regulations could impact its status, highlighting the evolving regulatory landscape surrounding HHC in the state.
Vermont	Gray Area	In Vermont, the legality of HHC remains uncertain due to regulations prohibiting the use of synthetic cannabinoids in hemp products, potentially impacting its status similar to delta 8. The determination of HHC's legality will depend on whether it's considered synthetic and subject to similar restrictions as delta 8.
Wisconsin	Gray Area	While hemp-derived CBD products are legal under Wisconsin Act 68, laws don't explicitly address HHC's status. As it's synthetically created.
Arkansas	Likely illegal	Arkansas’s laws don’t specifically address the legal status of HHC cannabinoid. They strictly outlaw all THC extracts (including hemp-derived ones) as Schedule VI Controlled Substances.
Delaware	Likely illegal	In Delaware, there are no explicit laws regarding the legality of hexahydrocannabinol (HHC). Hemp-derived items containing less than 0.3% delta 9 THC are permitted but lack regulation. Conversely, products containing THC and its isomers are prohibited under Title 16 of Delaware’s Uniform Controlled Substances Act. Given that HHC is a THC isomer, its legal status within the state remains ambiguous.
Colorado	Illegal	Colorado, while having a thriving cannabis market, bans the sale of some hemp derivatives including HHC, to ensure product safety and maintain strict regulations.
Idaho	Illegal	Idaho remains staunchly against THC in any form. The state has not made any distinctions between Delta-9 THC and HHC, treating both as illegal.
Mississippi	Illegal	In Mississippi, HHC is classified as a Schedule 1 controlled substance, making its sale, possession, or consumption prohibited.
Montana	Illegal	Montana strictly prohibits all tetrahydrocannabinol, including HHC, emphasizing a stringent stance on cannabis derivatives.
Nevada	Illegal	Nevada classifies HHC and related THC isomers as controlled substances, making their sale and possession illegal.
New York	Illegal	New York has a firm stance against THC isomers, including HHC, making their production and sale illegal.
North Dakota	Illegal	In North Dakota, HHC is categorized as a controlled substance, prohibiting its distribution and consumption.
Utah	Illegal	Utah prohibits products based on HHC, THC-O, delta-8, and delta-10, regardless of their origin from hemp or marijuana.
Washington	Illegal	In Washington, HHC is a controlled substance, making its sale, production, and consumption illegal.

For each country listed as “Legal,” it’s important to note that the legality is contingent upon the product containing less than 0.3% delta-9 THC. This requirement aligns with federal regulations in the United States, where hemp-derived products are legal if they contain no more than 0.3% delta-9 THC on a dry-weight basis.

Hexahydrocannabinol (HHC) A hemp-derived cannabinoid chemically related to THC that can produce intoxicating effects and is regulated differently across U.S. states.

HHC Laws in the United States

Laws regulating HHC vary widely across the United States. Because the compound is typically derived from hemp and related to THC, states often regulate it through broader hemp or controlled-substance laws.

As a result, HHC legality falls into several categories depending on the state. Some states allow it under hemp laws, others permit it with restrictions, while some treat it as illegal or leave its status uncertain under current regulations.

States Where HHC Is Legal

In several states, HHC is considered legal when it is derived from hemp and contains no more than 0.3% delta-9 THC. These states generally follow the framework established by the 2018 Farm Bill, which legalized hemp and many hemp-derived cannabinoids.

States where HHC is legal include Alabama, Florida, Georgia, Indiana, Kansas, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New Jersey, New Mexico, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Virginia, and West Virginia.

States Where HHC Is Legal With Restrictions

Some states allow HHC but place additional limits on how it can be sold or distributed. These restrictions often involve product forms, sales channels, or regulatory requirements tied to hemp-derived cannabinoids.

States where HHC is legal with restrictions include Alaska, Arizona, California, Connecticut, Hawaii, Missouri, and Oklahoma. In these states, HHC may be limited to licensed retailers, restricted product types, or subject to specific hemp or cannabinoid regulations.

States Where HHC Is Likely Legal

In some states, HHC is generally considered legal even though it is not specifically addressed in state law. In these cases, its legality is usually inferred from broader hemp laws that allow hemp-derived compounds containing no more than 0.3% delta-9 THC.

States where HHC is likely legal include Iowa, New Hampshire, Rhode Island, and Wyoming. Because these states have not issued clear rules specifically covering HHC, its legal status may depend on how existing hemp or cannabinoid regulations are interpreted.

States Where HHC Laws Are a Gray Area

In several states, the legal status of HHC remains unclear due to ongoing legislative discussions or gaps in existing hemp regulations. In these situations, lawmakers or regulators are still evaluating how intoxicating hemp-derived cannabinoids should be treated under state law.

States where HHC falls into a gray area include Illinois, Kentucky, Texas, Vermont, and Wisconsin. Because regulations surrounding hemp-derived cannabinoids continue to evolve, the legal status of HHC in these states may change as new rules or legislation are introduced.

States Where HHC Is Likely Illegal

In some states, HHC is not explicitly named in law but is generally treated as illegal because state rules prohibit THC extracts or similar cannabinoids. In these cases, regulators may interpret HHC as falling under broader bans on THC isomers or controlled cannabis compounds.

States where HHC is likely illegal include Arkansas and Delaware. Although HHC is not always specifically listed in statutes, existing controlled substance laws or restrictions on THC-related compounds make its legality uncertain and potentially prohibited.

States Where HHC Is Illegal

Several states explicitly prohibit HHC or classify it alongside controlled THC compounds. These bans typically stem from laws restricting THC isomers, synthetic cannabinoids, or hemp-derived intoxicating substances.

States where HHC is illegal include Colorado, Idaho, Mississippi, Montana, Nevada, New York, North Dakota, Utah, and Washington. In these states, the sale, possession, or production of HHC products is generally prohibited under existing controlled substance laws.
