THV-N10: effects, reviews and status, what we really know
By the Golden High teamUpdated 9 October 20269 min read
Novel cannabinoids
THV-N10 is a trade name given to a lab-made novel cannabinoid that turned up in French CBD shops in late 2024, sold as infused flowers, resins and vapes. Its chemical formula has never been published and no scientific study describes it under that name. Everything going around about its effects comes from sellers and from user feedback. Here's what's claimed, what's actually established, and where the rules stand in France.
Amnesia Delta-P 12 %
Our most popular flower: a moderate, clearly stated level, a lemony profile, below 0.3% THC and lab-tested.

Gelato Delta-P 10 %
A 10% level, among the gentlest of our Delta-P flowers. For a light session, with a clear figure on the label.

THV-N10, a trade name above all.
THV-N10 isn't a chemist's name. It's a market label that appeared in French CBD shops after France banned HHC (2023), then THCP and H4-CBD (2024). The name refers to a lab-made active ingredient, sprayed onto hemp flowers or blended into resins, e-liquids and gummies. So a “THV-N10 flower” isn't a strain that produces this molecule: it's a hemp flower that has had an active ingredient added to it.
That's where the trouble starts: nobody has published what this active ingredient actually is. No full chemical name, no formula, no identification number. At the time of this update, searching for the term “THV-N10” in PubMed, the reference database for biomedical publications, returns no results.
A word on the acronym: “THV” is also an old abbreviation for THCV, tetrahydrocannabivarin, a natural hemp cannabinoid. Nothing shows that the THV-N10 on sale has anything to do with it. We've written a piece on another name from the same series: THV2.
Sorting it out
What sellers say, what's established.
We read the product pages and articles from shops that sell or have sold THV-N10. They don't describe the same thing. That's the first signal to keep in mind: when three sellers give three different origins for one molecule, none of them can be verified.
| Topic | What sellers say | What's established |
|---|---|---|
| Origin | “Obtained from THCV” for one, “a supercharged 10-OH-HHC” for another, “extracted from hemp” for a third | No published structure, no independent analysis of the active ingredient |
| Effects | Relaxation, euphoria, a gradual onset, “gentler than HHC” | No trial in humans or in animals under this name |
| Potency | High percentages shown on product pages | No mandatory check on the dose; labelling discrepancies are documented on similar products |
| Status | “Legal”, “not classed as a controlled drug” | Not named by the ANSM; the 2024 French classification targets a whole family by its structure |
This article was fully updated in October 2026: nobody can claim that THV-N10 “isn't banned”, and you'll see why further down. To place this name among the others, our HHC, THC, THCP and Delta-P comparison goes through them molecule by molecule.
What the sources say
The only solid data doesn't carry this name.
With no study on THV-N10 itself, you have to look at what official bodies and laboratories have published on the novel cannabinoid family. The references are at the bottom of the page.
PubMed · October 2026
Zero publications for “THV-N10” or “THV N10”. No pharmacology, no toxicology, no reference dosing.
Drug Testing and Analysis · 2025
Japanese researchers analysed two commercial e-liquids. The one labelled “80% 10-OH-HHC” contained no 10-OH-HHC, but CBD, CBN and compounds attributed to isomers of tetrahydrocannabidiol. The authors' conclusion: labels can't be trusted.
EUDA · European Drug Report 2025
In 2024, 20 new cannabinoids were identified in Europe, 18 of them semi-synthetic. By the end of 2024, 24 semi-synthetic cannabinoids had been spotted on the European market.
DGS-Urgent · 11 June 2026
The DGS, France's directorate-general for health, counts around 500 reports linked to synthetic cannabinoids between early 2025 and the end of April 2026, often via e-liquids presented as lawful or sold as “CBD”. This alert doesn't mention THV-N10: it describes the market this kind of product circulates on.
The tetrahydrocannabidiol mentioned in the Japanese study is H4-CBD, classed as a controlled drug in France since June 2024. In other words: a product sold under one name can contain something else, including a banned molecule.
Effects and reviews
THV-N10 effects: testimonials, not measurements.
“Reviews” of THV-N10 come from two sources: the shops that sell it and feedback from users. Here's what comes up most often, to be taken as statements and nothing more.
- Marked physical relaxation and a feeling of euphoria.
- An onset described as gradual when vaped, with effects said to last a long time.
- On the side-effect front: dry mouth, red eyes, tiredness, mental fog, and for some people anxiety or a racing heart.
Is THV-N10 psychoactive? Everything points that way: sellers themselves talk about euphoria and compare it to HHC or THC. But no measurement tells us how strongly, or at what dose. And since nobody knows which molecule is in which product, two “THV-N10” items bought in two different shops can produce completely unrelated effects.
If the difference between CBD and lab-made molecules isn't clear to you, start with CBD and novel cannabinoids: what's the difference.
The rules in France
Is THV-N10 legal? Nobody can say so.
As far as we know, no ANSM decision mentions THV-N10 by name. Many sellers conclude from this that it's permitted. That reasoning hasn't held up since 2024, because France's list of controlled drugs no longer works on a name-by-name basis alone.
13 June 2023
HHC, HHC-O and HHC-P are classed as controlled drugs in France by the ANSM.
3 June 2024
The decision of 22 May 2024 comes into force: H4-CBD and H2-CBD are listed, along with any substance derived from the “benzo[c]chromene core”, the structure shared by THC and HHC. HHCPO, THCP and THCA are given as examples. CBN is excluded.
6 June 2025
The Conseil d'État, France's highest administrative court, rejects the appeals brought by CBD businesses and upholds this classification by structural family.
Today
The ANSM keeps monitoring new cannabinoids. The rules change, sometimes within a matter of days.
The upshot: if THV-N10 really is, as some sellers write, a derivative of HHC or 10-OH-HHC, it may fall within that family even without being named. And since its structure isn't published, neither you nor the shop can check.
Key takeaway: “not on the list” doesn't mean “legal”. A THC level below 0.3% tells you nothing either: that threshold is about the THC in hemp, not the active ingredient added to it. So we won't tell you that THV-N10 is legal.
Before you buy
What makes this kind of product risky.
- An unknown molecule. With no published formula, there's no toxicology, no reference dose, and no information on duration or interactions.
- Labelling you can't verify. Nobody checks the stated level. Published analyses of similar products show contents that don't match the label.
- One name covering several products. The same acronym can refer to different active ingredients from one supplier to the next, or even from one batch to the next.
- Vapes, the most exposed format. E-liquids account for most of the synthetic cannabinoid poisonings reported to the authorities.
- A legal risk. Holding a product that turns out to contain a classified substance means holding a controlled drug, whatever the label says.
If you already have a product like this in your hands, the basic harm-reduction rules apply: adults only, a very small amount, wait before taking more, don't mix it with alcohol or other substances, and never drive afterwards. If you notice any unusual effect: in France, call a poison control centre or 15 (SAMU); anywhere in Europe, call 112, the European emergency number. To see how far this is from true synthetic cannabinoids, read our article on ADB-PINACA.
Where we stand
We don't sell THV-N10, and here's why.
Today Golden High sells only its Delta-P range, based on CBDX, below 0.3% THC and lab-tested. None of our products contains THV-N10. The details of what Delta-P is are on our dedicated page.
Ask which molecule it is
A serious seller can tell you what they're selling and provides a lab analysis of the batch. A code name alone isn't enough.
Pick a clear level
Our flowers state their level: Amnesia 12% or Gelato 10% to begin with. The whole range is in the Delta-P flowers collection.
Start low
One or two puffs, then wait. For adults only, and never before driving.
Your questions
What people ask us about THV-N10.
What is THV-N10?
A trade name given to a lab-made novel cannabinoid, sold on infused flowers, in resins and in vapes. Its chemical formula hasn't been published and no scientific study describes it under that name.
Is THV-N10 legal in France?
Nobody can say so. It isn't named by the ANSM, but since 3 June 2024 the French list of controlled drugs has targeted a whole family of cannabinoids defined by its structure. With no published formula, there's no way of knowing whether THV-N10 belongs to it.
Is THV-N10 psychoactive?
Going by descriptions from sellers and users, yes: euphoria, marked relaxation, effects compared to those of HHC or THC. No study measures this effect or the dose at which it appears.
What are the effects of THV-N10?
The reported effects are physical relaxation, euphoria and a gradual onset, with dry mouth, red eyes, tiredness and sometimes anxiety or palpitations. These are testimonials, not scientific data.
How much are THV-N10 reviews worth?
They mostly come from shops that sell it and from users who don't know exactly what was in their product. They say nothing about safety, and two products carrying this name can contain different active ingredients.
Is a THV-N10 flower a cannabis strain?
No. It's a hemp flower that a lab-made active ingredient has been sprayed onto. The plant doesn't produce this molecule.
Does Golden High sell THV-N10?
No. The shop only sells its Delta-P range, based on CBDX, below 0.3% THC and lab-tested.
