HHC is legal in North Carolina right now, but that window is closing. A federal law signed on November 12, 2025, rewrites the definition of hemp in a way that excludes HHC, and enforcement begins exactly one year later on November 12, 2026. Until then, HHC products containing no more than 0.3% delta-9 THC remain lawful under both federal and North Carolina law.
Why HHC Is Legal in North Carolina Today
The 2018 Farm Bill removed hemp from the federal definition of marijuana and defined hemp broadly to cover the cannabis plant and all its derivatives, extracts, and cannabinoids, as long as the delta-9 THC concentration stays at or below 0.3% on a dry weight basis.1U.S. Food and Drug Administration. Hemp Production and the 2018 Farm Bill That language was wide enough to cover cannabinoids like HHC that barely exist in the natural plant but can be manufactured from legal hemp.
North Carolina adopted the same framework. The state’s definition of hemp in G.S. 90-87(13a) mirrors the federal language.2North Carolina General Assembly. North Carolina Code G.S. 90-87 – Definitions In 2022, the legislature went further with Session Law 2022-32, amending G.S. 90-94 to explicitly exclude tetrahydrocannabinols found in hemp or hemp products from the state’s controlled substances schedules.
A federal court ruling locked the interpretation in place for North Carolina. In September 2024, the U.S. Court of Appeals for the Fourth Circuit decided Anderson v. Diamondback Investment Group, rejecting the DEA’s argument that chemically processed hemp cannabinoids are automatically illegal. The court held that whether a product qualifies as hemp turns on its source and its delta-9 THC level, not the manufacturing method.3Fourth Circuit Court of Appeals. Anderson v. Diamondback Investment Group, LLC Under that ruling, HHC made from legal hemp and containing less than 0.3% delta-9 THC counts as lawful hemp.
The Federal Ban Beginning November 12, 2026
That legal foundation is about to collapse. On November 12, 2025, Congress enacted the Continuing Appropriations and Extensions Act, 2026 (Pub. L. No. 119-37). Section 781 rewrites the federal definition of hemp under 7 U.S.C. ยง 1639o, with enforcement starting exactly 365 days later on November 12, 2026.4Office of the Law Revision Counsel. 7 USC 1639o – Definitions
The new definition kills HHC’s legal status in three distinct ways. First, it excludes products containing cannabinoids “not capable of being naturally produced by a Cannabis sativa L. plant.” HHC falls squarely in that category, since commercial HHC is synthesized in a lab rather than extracted from the plant at meaningful concentrations. Second, it excludes cannabinoids that are capable of being naturally produced by cannabis but were “synthesized or manufactured outside the plant,” which catches products like delta-8 THC made through CBD conversion. Third, the threshold shifts from delta-9 THC alone to “total tetrahydrocannabinols concentration (including tetrahydrocannabinolic acid),” with a 0.3% limit for raw hemp and a ceiling of 0.4 milligrams of total THC per container for finished products.
Once the enforcement date arrives, any product that fails the new definition becomes marijuana under the Controlled Substances Act and carries the same civil and criminal consequences. The Anderson ruling won’t help, because it interpreted the old statutory text, and Congress has now rewritten the text itself.
Where North Carolina State Law Sits
North Carolina has not updated its hemp statutes to reflect the incoming federal change. G.S. 90-87(13a) still tracks the original 2018 Farm Bill language, and the 2022 amendment to G.S. 90-94 still excludes hemp-derived THC from the state’s controlled substances schedules.2North Carolina General Assembly. North Carolina Code G.S. 90-87 – Definitions
After November 12, 2026, that creates a conflict. HHC will be federally illegal, but North Carolina’s statutes may still technically treat it as a legal hemp derivative until the legislature acts. In practice, that gap offers little comfort. Federal law enforcement can pursue violations of the Controlled Substances Act regardless of state law, and retailers, payment processors, and shipping carriers tend to follow federal classifications.
Legislation is pending. Senate Bill 265, filed in the 2025 session, would set a minimum purchase age of 21, require certificates of analysis from independent labs, mandate ingredient lists and batch numbers, and ban hemp cannabinoid products sold as food or beverages. Violations would be a Class 2 misdemeanor for a first offense and a Class 1 misdemeanor for repeat offenses.5North Carolina General Assembly. Senate Bill 265 – Regulate Hemp-Derived Cannabinoid Products Whether SB 265 or similar legislation passes before the federal deadline is unknown.
As of now, North Carolina has no minimum age for buying HHC or other hemp-derived cannabinoid products, no purchase quantity limits, and no mandatory quality standards at the state level.
What You Can Still Get in Trouble For
Legal to buy does not mean risk-free to use. Three issues trip people up even during the current legal window.
Driving After Use
North Carolina’s impaired driving statute, G.S. 20-138.1, makes it a crime to drive while “under the influence of an impairing substance.”6North Carolina General Assembly. North Carolina Code G.S. 20-138.1 – Impaired Driving That language covers any substance that impairs your ability to drive, not just alcohol or illegal drugs. HHC qualifies. Unlike alcohol, there is no legal concentration threshold for cannabinoids in North Carolina, so you don’t need to be above a specific blood level to be charged. If an officer observes signs of impairment and connects them to HHC use, that can be enough. Buying the product legally is not a defense.
Drug Tests
HHC will almost certainly cause you to fail a standard drug test. The metabolites your body produces when it breaks down HHC are structurally similar enough to THC metabolites that they trigger the same immunoassay tests used in workplace screening. No standard drug panel distinguishes between THC from marijuana and metabolites from legal hemp cannabinoids.
For safety-sensitive transportation workers, the stakes are highest. The Department of Transportation states that it “remains unacceptable for any safety-sensitive employee subject to drug testing under the Department of Transportation’s drug testing regulations to use marijuana,” and its testing protocols under 49 CFR Part 40 have not changed to account for legal hemp products.7US Department of Transportation. DOT Notice on Testing for Marijuana Pilots, truck drivers, school bus drivers, train engineers, and other covered employees face the same consequences for a positive test regardless of the substance’s legal status.
Employer Policies
Private employers in North Carolina are generally free to enforce zero-tolerance drug policies that make no distinction between marijuana and hemp-derived cannabinoids. A positive test can cost a job offer or trigger termination even if HHC is legal in the state at the time you used it. If your employer tests for THC, treat HHC the same way you would treat marijuana when weighing your risk.
Buying HHC Before the Ban
If you’re buying HHC during the remaining legal window, product quality matters more than usual in an unregulated market. Look for a current certificate of analysis from an independent third-party laboratory. That document should confirm HHC potency, verify the delta-9 THC concentration is at or below 0.3%, and show the product was screened for pesticides, heavy metals, and residual solvents from the manufacturing process.
Be skeptical of products without lab results, or with results from the manufacturer’s own lab rather than an independent facility. The hydrogenation process used to make HHC can produce unwanted byproducts if done carelessly, and without state regulatory oversight, testing is the only safeguard. A reputable vendor will make current lab reports accessible before purchase, usually through a QR code on the packaging or a link on their website.
After November 12, 2026
Once the enforcement date passes, possessing, selling, or manufacturing HHC will carry the same federal legal risk as marijuana. Products that don’t meet the rewritten definition of hemp become controlled substances under the CSA.4Office of the Law Revision Counsel. 7 USC 1639o – Definitions
North Carolina may pass its own legislation before that deadline, either aligning with the federal ban or carving out protections for certain products. Until that happens, the safest assumption is that HHC will be treated as an illegal substance under federal law starting November 12, 2026, with state enforcement likely to follow. If you currently use or sell HHC in North Carolina, plan around that date rather than hoping the timeline shifts.
