Is 10-OH-HHC Legal? The German Ban Explained

Time: 13 min
Search is 10-OH-HHC legal and you'll still find pages calling it a legal HHC alternative, or a grey zone. That was true for about seventeen months. Then, on 2 December 2025, it stopped. Since that day, 10-OH-HHC (also written 10 OH HHC) has been covered by Germany's New Psychoactive Substances Act, the NpSG, even though no German law mentions it by name. This guide shows you the exact clause that catches it. It also covers the part most pages get wrong, the gap between what's prohibited and what's actually a crime, plus why shops could sell it until late 2025 and where the law leaves anything bought before the ban. Every legal statement links to the official text.
Short answer: No. 10-OH-HHC is banned in Germany. Since 2 December 2025 it falls under the cannabinoid group definition of the NpSG (Anlage 1 Nr. 2.3), whose hydroxy clause was added by the sixth NpSG amending ordinance. Selling, trading, making it for sale or importing it for sale are criminal offences. Buying and possessing it are prohibited, and police or customs can seize it, but possession on its own isn't a criminal offence under the NpSG.

Is 10-OH-HHC Legal in Germany?
No. 10-OH-HHC is a semi-synthetic cannabinoid: HHC with one extra hydroxyl (OH) group at position 10 of its ring. That one hydroxyl group is the whole legal story. It's what kept 10-OH-HHC outside German law in 2024 and 2025, and it's exactly what the law was changed to cover. Want to know what 10-OH-HHC actually is, or what's known about its effects? That's in our 10-OH-HHC effects and side effects guide. This page sticks to the law.
Why the NpSG Covers 10-OH-HHC Without Naming It
The NpSG isn't a list of names. It defines whole families of substances by their chemical structure, so a new variant is caught the moment it fits the description (the name never comes into it). For cannabinoids, the family is group 2.3: substances built on a 6H-benzo[c]chromen-1-ol core, with certain add-ons allowed, up to a molecular mass of 600 u.
The clause that matters is 2.3.2 a). Since 2 December 2025 it reads, in part: "Der Ring A kann an jeder Position mit beliebigen Kombinationen folgender Atome und Atomgruppen (Rn) substituiert sein: Wasserstoff, Brom, Chlor, Fluor, Iod, Hydroxy-, … Methyl- …" In plain English: ring A may carry a hydroxy group, or a methyl group, at any position. Lay 10-OH-HHC over the definition and every feature fits.
Feature of 10-OH-HHC |
What Anlage 1 Nr. 2.3 allows |
Fits? |
Fully saturated ring A (the "hexahydro" part) |
Any degree of hydrogenation of ring A (2.3.1) |
Yes |
Methyl group at position 9 |
Methyl at any position on ring A (2.3.2 a) |
Yes |
Hydroxyl group at position 10 |
Hydroxy at any position on ring A (2.3.2 a, since 2 December 2025) |
Yes |
Five-carbon (pentyl) side chain |
A carbon chain of up to 12 atoms (2.3.2 c) |
Yes |
Molecular mass of about 332.5 u (C21H32O3) |
Maximum 600 u |
Yes |
The government was open about why the hydroxy clause went in. Its official explanatory memorandum ( Bundesrat printed paper 534/25) says the definition was extended to "halogenierte und hydroxylierte Derivate am Ring A" (halogenated and hydroxylated derivatives on ring A) "aufgrund von Sicherstellungen". In plain terms, because these substances were being seized.
Why 10-OH-HHC Could Be Sold Until December 2025
HHC itself came under the NpSG on 27 June 2024, through the fifth amending ordinance ( BGBl. 2024 I Nr. 210). That version of group 2.3 allowed a methyl group (or a few other add-ons) at position 9 of ring A. Nowhere else on the ring.
A hydroxyl group at position 10 wasn't in it, so from the day HHC was banned, its hydroxylated version sat just outside the definition. Shops sold it as the "legal successor".
The sixth ordinance closed that gap. The Bundesrat approved it on 21 November 2025, it was published in the Federal Law Gazette on 1 December 2025, and it took effect the next day. No transition period.

What's Prohibited and What's a Crime
Most pages get this line wrong. The NpSG prohibits a long list of acts in § 3, but only some of them carry a criminal penalty, and those sit in § 4.

Prohibited but not punishable doesn't mean allowed. Police can seize and destroy any 10-OH-HHC they find (§ 3 Abs. 3). Customs can seize it at the border too, with the storage costs charged to whoever is responsible (§ 3 Abs. 4).
Penalties
The penalties sit in § 4 NpSG.
- Trading, selling, administering, or making or importing to sell: up to three years in prison or a fine. Attempt is also punishable.
- Acting commercially or as part of a gang, or an adult over 21 supplying it to someone under 18, or endangering the health of many people, or exposing someone to the risk of death or serious harm: one to ten years. In less serious cases of these, three months to five years.
- Negligent trading, selling or administering: up to one year in prison or a fine (§ 4 Abs. 6).
Ordering 10-OH-HHC From Abroad
Ordering from a shop in another country doesn't get you around the ban. Bringing 10-OH-HHC into Germany is prohibited under § 3. For resale, that's a criminal offence. For yourself, it isn't a crime under the NpSG, but customs can seize the parcel and pass on the costs. Does it matter whether the sender's country allows it? No, not once the parcel crosses the German border.
Products That Also Contain HHC
The EU Drugs Agency has found that semi-synthetic cannabinoid products can contain undeclared cannabinoids, at levels that vary between batches. So what if a product sold as 10-OH-HHC also contains HHC? Then the stricter law applies to that part. Since 23 May 2026, HHC is a narcotic under the BtMG, where possessing it without a permit is a criminal offence on its own. Our guide to HHC's legal status has the details.
10-OH-HHC Bought Before the Ban
Buying 10-OH-HHC before 2 December 2025 was legal. Keeping it after that date isn't. The ordinance took effect the day after publication with no grandfather clause, so possession has been prohibited since 2 December 2025, no matter when you bought the product. Not a criminal offence on its own. Any stock can still be seized.
10-OH-HHC, Driving and Drug Tests
Germany's cannabis limit for drivers (§ 24a Abs. 1a of the Road Traffic Act, StVG: 3.5 ng/ml in blood serum) is set for THC only, and 10-OH-HHC isn't among the other substances § 24a lists either. That isn't a loophole. Driving while impaired by any intoxicating substance can still be a criminal offence (§ 316 StGB), and products sold as 10-OH-HHC may contain undeclared THC.
Testing is its own question. Labs can measure 10-OH-HHC: a 2026 Leipzig study built a method that detects it in blood and urine down to about 0.1 ng/ml ( Höfert et al. 2026). That study looked for it as a breakdown product after people took HHC, though, and found none. Nobody has tested people who took 10-OH-HHC itself. Whether rapid roadside or workplace tests react to it is unknown. Our 10-OH-HHC effects guide covers what's known about detection.
Is 10-OH-HHC Legal in Austria, Switzerland and the Rest of Europe?
There's no EU-wide rule on 10-OH-HHC. Each country decides for itself, and Germany acted later than Austria or Switzerland. Here's where the countries we could check against their own official texts stand.

A few details matter more than the table can show:
- Austria: making, importing, exporting or passing it on is a crime under § 4 of the Austrian NPSG (up to two years) when it's done for gain and for its psychoactive effect. Possession isn't an offence under the NPSG, but the substance can be confiscated.
- Switzerland: anyone who makes, imports, stores, uses or sells it without a permit commits an offence under Art. 20 of the Narcotics Act (BetmG). The entry states that private use isn't exempt.
- France: this is the one with the most confusion. France banned HHC and a broad family of related cannabinoids in 2023 and 2024. Its 2024 generic rule lists the ring positions it covers (1, 2 or 4, 3, 6 and 9), and position 10 isn't among them. So whether 10-OH-HHC is caught is legally unsettled, and we found no statement on it from the French regulator (ANSM). Pages that call it either "interdit" or legal in France are going further than the text does.
- United Kingdom: supplying, producing or importing it is an offence under the Psychoactive Substances Act. Simple possession isn't, except in prisons. A draft order would make 10-OH-HHC a Class B drug, but as of 26 October 2026 it hasn't been made.
This list isn't complete. If you're outside Germany, check your own country's official sources.
Why Some Pages Still Say 10-OH-HHC Is Legal
- They were written before December 2025. Between June 2024 and 1 December 2025, "not covered by the NpSG" was accurate. Plenty of those pages are still online, some with a "2026" in the title and the old legal section underneath (a fresh date on old text).
- The annex was renumbered. Since 12 April 2026 the cannabinoid group sits in "Anlage 1", not "the Anlage". Search the law for the old reference, or for the name "10-OH-HHC", and you won't find either.
- The name isn't in the law. "Not named" gets read as "not banned", but the NpSG doesn't need a name, as the feature table above shows.
- Sellers had stock to move. A lot of the "still legal" or "grey zone" content sits on shops that sold it.
Has a Court Ruled on 10-OH-HHC?
We found no published court decision on 10-OH-HHC. The ban rests on the wording of the NpSG itself. On the points that matter, the hydroxy group, the side chain and the mass limit, that wording is unambiguous.
A Nine Realms Look at 10-OH-HHC Legality
The previous version of this page called 10-OH-HHC a grey area. It said the substance was regulated through novel-food rules, and it described court cases we can't find any trace of. The NpSG never came up once. All of that is gone. A legal question deserves the actual text of the law, a date and a source, so that's what this page gives you now.
The short version hasn't changed since 2 December 2025: 10-OH-HHC is banned in Germany. Selling it is a crime. Owning it isn't, but it can be taken from you. If a page tells you otherwise, check when it was written and whether it cites the law. This is a summary, not legal advice.
FAQ
Is 10-OH-HHC legal in Germany?
No. No law names it, but since 2 December 2025 it falls under the NpSG's cannabinoid group definition (Anlage 1 Nr. 2.3). Selling it is a criminal offence. Possessing it is prohibited.
Since when has 10-OH-HHC been banned?
Since 2 December 2025, the day after the sixth NpSG amending ordinance (BGBl. 2025 I Nr. 292) was published. The Bundesrat had approved it on 21 November 2025.
Is it a crime to possess 10-OH-HHC?
Not in itself. The NpSG prohibits possession and lets police seize the substance, but its criminal offences cover selling, trading, administering, and making or importing for sale. HHC is different. Since 23 May 2026 it's been a narcotic under the BtMG, where possession without a permit is a crime. This is a summary, not legal advice.
Will 10-OH-HHC be banned in Germany?
It already is. 10-OH-HHC has been covered by the NpSG since 2 December 2025. Pages that discuss a possible future ban were written before that date.
Why is 10-OH-HHC banned if no law names it?
Because the NpSG bans whole substance groups by structure, not by name. Group 2.3 allows a hydroxy group at any position on ring A, and 10-OH-HHC fits every other part of the definition too: the ring, the methyl group, the side chain and the mass limit.
What happens to 10-OH-HHC I bought before the ban?
Possession has been prohibited since 2 December 2025, whenever you bought it. There's no grandfather clause. It isn't a criminal offence on its own, but it can be seized.
Can I order 10-OH-HHC from another country?
Bringing it into Germany is prohibited. For resale, it's a criminal offence. For your own use, it isn't a crime under the NpSG, but customs can seize it.
Does a lab certificate or a "less than 0.2 % THC" label make 10-OH-HHC legal?
No. The ban covers 10-OH-HHC itself, whatever else the product does or doesn't contain.
Is there an amount of 10-OH-HHC I'm allowed to have?
No. The NpSG has no personal-use allowance and no "small amount" rule. Any amount is prohibited, and any amount can be seized.
Is 10-OH-HHC the same as HHC-O?
No. HHC-O is HHC with an acetate group attached; 10-OH-HHC is HHC with an extra hydroxyl group on its ring. Different compounds. Our HHC-O guide covers HHC-O.
Is possessing HHC a crime?
Yes, since 23 May 2026. HHC is now a narcotic under the BtMG, where possession without a permit is a criminal offence. See our HHC legal status guide.
Is 10-OH-HHCP legal?
No. The same clause caught it on the same day, 2 December 2025. Our 10-OH-HHCP guide covers it in detail.
Is 10-OH-HHC legal in Austria or Switzerland?
No. Austria has covered it through a group definition in its New Psychoactive Substances Ordinance since March 2023. Switzerland has covered it since 5 November 2024 through the cannabinoid entry in narcotics list e. The details differ from Germany, see the Europe section above.
