The legal status of HHC (hexahydrocannabinol) and other semi-synthetic cannabinoids in Europe has radically shifted in 2024–2025, marked by a synchronized wave of bans, regulatory carve-outs, and newly tightened enforcement across much of the region. While these compounds saw a commercial boom from 2022 through early 2024, national health authorities and EU-level bodies have since moved swiftly to restrict their availability—a direct response to emerging public health and consumer safety concerns. Despite this overarching trend, one EU member continues to permit HHC, setting up a distinctive outlier scenario that both brands and regulators are watching closely.
This blog post summarizes key developments in HHC legality in Europe as of late 2025, highlighting evolving regulations country by country, enforcement risks, and strategic compliance considerations for industry stakeholders. For ongoing updates, consult CannabisRegulations.ai.
HHC is a hydrogenated analog of THC, typically produced from hemp-derived CBD in a laboratory setting—making it a semi-synthetic cannabinoid. Related compounds (like THCP, HHCPO, and THCV) have followed HHC’s commercial footprint, usually marketed as legal alternatives to both THC and CBD with a similar psychoactive profile.
These substances have largely evaded traditional narcotics scheduling—until now. From late 2023 onward, EU states and the UK responded to reports of adverse reactions and unregulated markets by adopting substance-specific bans and broadening psychoactive-substances frameworks to capture new cannabinoid analogs.
France was among the first to prohibit HHC in 2023, with enforcement ramping up in 2024. The ban extends to all derivatives and closely related "neo-cannabinoids" that mimic THC’s effects. Source
In May 2024, Ireland classified HHC as an illegal drug under its Misuse of Drugs legislative schedule. As of 2025, the production, possession, import, export, sale, and supply of HHC products are criminal offences. Source
These countries have enacted restrictive legislation covering THC-like and HHC-like compounds, making virtually all semi-synthetic cannabinoids de facto illegal even if not explicitly scheduled. Source
Building on these actions, health ministries in multiple EU member states have expanded their controlled substances lists to include THCP, H3CBN, HHCPO, and similar compounds. This means most traditional and emerging HHC analogs are now covered—often through generic definitions designed to capture all psychoactive cannabinoid analogues. Source
While HHC is "not yet strictly prohibited," the UK Home Office signaled strong intent in late 2025 to ban HHC and related semi-synthetic cannabinoids. Enforcement actions against retailers and online distributors have already commenced as part of existing psychoactive substances legislation. Source
In stark contrast to much of Europe, the Netherlands permits the sale and use of HHC and most semi-synthetic cannabinoids as of September 2025. A July 2025 regulatory review maintained the legal sale of HHC products, with the Dutch government taking a "wait and monitor" approach as they evaluate marketplace safety data and EU harmonization discussions.
This makes the Dutch market a singular outlier—but stakeholders should closely watch signals from health authorities as further alignment with EU controls remains possible. Source
Brands and distributors face substantial legal risks moving product across European borders in 2025. With most EU states now listing HHC and similar cannabinoids as controlled substances, customs authorities are actively seizing shipments, and consumer-protection regulators have issued safety alerts targeting imported semi-synthetic cannabinoid products.
Key Takeaway: Implement country-specific shipping restrictions and geo-block SKUs in regions with bans or schedule listings. Cross-border e-commerce is especially high-risk in 2025.
As the regulatory climate hardens, many companies are reformulating product profiles to avoid intoxicating cannabinoids—either by shifting to non-psychoactive cannabinoid blends or pivoting to CBD-only or minor-cannabinoid formats. This can provide a pathway to compliance in select EU jurisdictions, though consumer demand and retailer confusion may suppress sales.
Where HHC is (narrowly) legal, such as in the Netherlands, products must adhere to stringent labeling, notification, and product-safety standards, including child-resistant packaging, accurate cannabinoid content disclosure, and shelf-life declarations. In jurisdictions with complete bans, the sale or advertisement of HHC in any form may be prosecuted as an offense under narcotics or consumer safety law.
As of September 2025:
The environment for semi-synthetic cannabinoids in Europe is rapidly closing under the weight of health ministry and regulatory action. As of late 2025:
