Updated August 6, 2026: Added the UK's planned Class B classification (announced August 2025, not yet in force), the Netherlands' Opium Act ban (effective July 2025), Belgium's and Ireland's explicit prohibitions, and the March 2025 UN scheduling decision that obliges all treaty countries to control HHC.
HHC — hexahydrocannabinol — had a remarkable two-year run as Europe's most popular legal high. That window has largely closed. Most major European markets have now banned HHC explicitly, the UK captured it through its own legal mechanism, and in March 2025 the UN Commission on Narcotic Drugs placed HHC under Schedule II of the 1971 Convention on Psychotropic Substances — obliging every treaty country to control it. Here's where things stand country by country in 2026.
HHC is illegal to produce, supply, or import in the United Kingdom. Under the Psychoactive Substances Act 2016, HHC is prohibited — not because it appears by name on a specific banned substance list, but because the Act captures it by category: it bans any substance capable of producing a psychoactive effect in humans, other than specified exemptions (alcohol, tobacco, caffeine, medical products). HHC produces psychoactive effects. It's prohibited from sale.
The UK is also moving to harden that position. In August 2025, following an Advisory Council on the Misuse of Drugs (ACMD) report on semi-synthetic cannabinoids, the government confirmed it will place HHC and eleven related compounds in Class B of the Misuse of Drugs Act 1971 (and Schedule 1 of the Misuse of Drugs Regulations 2001). As of August 2026 that order has not yet been made — the Home Office said controls will be implemented "when parliamentary time allows" — so the Psychoactive Substances Act remains the operative ban; once the Class B order takes effect, simple possession will also become a criminal offence. (The government declined to immediately control THCA, opting for stakeholder consultation first.)
UK Border Force has documented seizures of HHC products imported primarily from the Netherlands and Poland since 2023. Domestic online retailers who were briefly selling HHC in 2022–2023 faced enforcement notices and shuttered. The UK market for legal HHC is effectively gone.
Germany: HHC was added to the German Narcotics Act (Betäubungsmittelgesetz) via decree in 2023. The ban covers HHC, HHCO, and HHCP. German authorities have been among the most active in enforcement, conducting raids on CBD shops selling HHC products in Hamburg, Berlin, and Munich.
France: ANSM classified HHC, HHCO, and HHCP as narcotics in June 2023. The ban has since been extended to additional HHC derivatives and related neo-cannabinoids.
Austria: Austria added HHC to its controlled substances list in 2023. The Austrian Medicines and Narcotics Act was amended to capture HHC by name.
Czech Republic: In early 2024, the Czech Republic updated its controlled substances list to include HHC, HHC-O, and THCP. By July 2024, additional compounds — HHC-P, HHC-B, HHC-H — were also banned.
Netherlands: The long-standing Dutch gray zone closed in 2025. HHC was added to the Opium Act with a ban on sales effective July 1, 2025, and in January 2026 HHC — along with HHCP and THCP — was moved to Opium Act List I, the hard-drugs list, bringing criminal enforcement.
Belgium: Prohibited. A royal decree of April 2024 confines HHC and related cannabinoids to a licensed pharmaceutical-only framework; commercial retail is closed.
Ireland: In 2025 the Irish government classified HHC as an illegal drug under the Misuse of Drugs framework, ending its brief vape-shop availability. Irish health authorities had flagged HHC-linked psychosis presentations in the run-up to the ban.
Luxembourg: Broad NPS legislation likely captures HHC, but no explicit HHC-specific prohibition has been issued. The practical result: HHC exists in a legally contested space — and the 2025 UN scheduling decision points only one direction.
Portugal, Spain: Generally more permissive cannabis enforcement policies. Neither country has enacted an explicit HHC ban, and both saw HHC products remain on shelves longer than in northern Europe. The window is closing: as UN treaty parties both are now obliged to control HHC following the March 2025 CND decision, Portuguese authorities began coordinated enforcement operations in 2026, and a Portuguese implementing decree is expected before year-end.
The EU drugs agency (EUDA, formerly the EMCDDA) flagged HHC and related compounds in 2022–2023 as psychoactive substances of concern, and its coordination across EU member states accelerated the regulatory response. The core concern: HHC is produced by hydrogenating THC or CBD, a process that creates a compound with limited clinical study data. European health ministries applied the precautionary principle: insufficient safety data plus psychoactive effects equals prohibition. The March 2025 UN Commission on Narcotic Drugs decision to place HHC in Schedule II of the 1971 Convention internationalized that answer — treaty parties, which include every European state, must now control it domestically.
As each wave of cannabinoids gets banned, manufacturers develop new molecules that briefly exist in legal gray zones. After HHC came THCP, H4CBD, and HHCPO. After those were banned in France and elsewhere, 10-OH-HHC emerged. This regulatory whack-a-mole has led the EUDA and several national agencies to push for "analog act" legislation — banning entire chemical families rather than specific molecules; the UK's pending Class B order and the Czech group listings are early examples of the family-based approach.
Don't. Carrying HHC products through European countries — especially those with explicit bans like France, Germany, the Netherlands, and the UK — creates real criminal exposure. The "it's hemp-derived" argument does not work in these jurisdictions. If you need cannabinoids while traveling in Europe, stick to CBD products with verified lab documentation showing compliance with local THC limits.
No. HHC cannot be legally sold, supplied, or imported in the UK under the Psychoactive Substances Act 2016, and the government confirmed in August 2025 that it will be made a Class B drug under the Misuse of Drugs Act — a change that will also criminalize possession once the order is made. There is no legal pathway for HHC retail in the UK.
No. HHC was added to Germany's Narcotics Act in 2023 and is explicitly prohibited.
In most major European markets, yes. France, Germany, Austria, the Czech Republic, the Netherlands, Belgium, and Ireland have explicit bans. The UK prohibits it under the PSA with a Class B order pending. Since March 2025, HHC is also internationally scheduled under the 1971 UN Convention, so remaining holdouts are obliged to follow.
Explicitly banned: UK, Germany, France, Austria, Czech Republic, Netherlands, Belgium, Ireland. Likely captured by broad NPS legislation: Luxembourg, Italy. Less restricted but tightening under the UN scheduling obligation: Portugal, Spain.
CBD derived from legal hemp is explicitly permitted in most European countries, including the UK (with strict THC limits), France, Germany, and others. HHC is a psychoactive compound that has been classified as a narcotic or controlled substance across Europe and, since 2025, under the UN psychotropics convention. They're in entirely different regulatory categories.
