Delta BZ10: what's in it, effects and status, what we really know
By the Golden High teamUpdated 9 October 20269 min read
Novel cannabinoids
Delta BZ10, often shortened to BZ10, isn't a molecule: it's a trade name given to a blend of active compounds, and the advertised recipe changes from one seller to the next. No scientific study has looked at it, and one of the most frequently listed ingredients, muscimol, has been banned in France since 11 July 2026. Here we sort what the shops claim from what's actually established.
Amnesia Delta-P 12%
Our most requested flower: a moderate, clearly stated level, a lemony profile, below 0.3% THC and lab-tested.

Jaune Mousseux 30%
The frothy resin that made the shop's name: supple texture, a denser effect, level shown on the product page.

Delta BZ10 is a blend, not a molecule.
Despite the chemical-sounding name, “Delta BZ10” doesn't match any catalogued substance. The term turned up in French CBD shops in late 2024 to describe a cocktail of active compounds sprayed onto hemp flowers or worked into resins, e-liquids and gummies. You'll see it written BZ10, BZ-10, Delta BZ or Delta-BZ10: it's all the same market name.
No manufacturer has published a technical sheet, the proportions or an independent analysis of the blend. A search on PubMed, the reference database for biomedical publications, returns no work at all on a cannabinoid by that name.
- What it is: the trade name of a blend, not a single molecule.
- Recipe: varies from seller to seller, with no published proportions.
- Formats sold: flowers, resins, vapes and e-liquids, gummies.
- At Golden High: not sold. The shop only stocks its Delta-P range.
What sellers say
A make-up that changes from shop to shop.
We compared the descriptions published by several French shops, along with our own original article. What you find is three versions that can't all be true at once.
| Version | Advertised composition | What it means |
|---|---|---|
| The “four-part” recipe | 10-OH-HHC, muscimol, CBN and CBC | Contains muscimol, banned in France since 11 July 2026 |
| The “three-part” recipe | 10-OH-HHC, THV-N10 and CBN | Two lab-made compounds out of three, one of them with no published formula |
| “Single molecule” | A synthetic cannabinoid presented as one single molecule | No structure and no scientific reference to back it up |
This article was fully updated in October 2026, because the rules have changed since its first version. Here's what can be said, ingredient by ingredient.
10-OH-HHC
A hydroxylated derivative of HHC, sold as a semi-synthetic cannabinoid. No clinical studies. In the United Kingdom, the advisory council on drugs recommended in 2025 that it be brought under control along with the other HHC derivatives.
Muscimol
It isn't a cannabinoid: it's an active compound from the fly agaric mushroom. In France, the ANSM (the French medicines agency) added it to the list of psychotropic substances after several serious poisonings.
CBN and CBC
Two cannabinoids naturally present in hemp. CBN is expressly excluded from the 2024 French classification. Sellers credit them with benefits for sleep or inflammation, which haven't been established for these products.
THV-N10
Another trade name, with no published formula. We go through what's known about it in our article on THV-N10.
What the sources say
What's actually established.
No official source deals with “Delta BZ10” as such. Its advertised ingredients and the market it circulates on, however, are documented. The references are at the bottom of the page.
ANSM · 3 July 2026
In France, muscimol and ibotenic acid are added to the list of psychotropic substances: sale, production and use are banned from 11 July 2026. The reason: serious poisonings, notably after gummies or chocolate, some of which ended in intensive care. Symptoms cited: deep drowsiness or coma, confusion, hallucinations, seizures.
Drug Testing and Analysis · 2025
Japanese researchers analyse an e-liquid labelled “80% 10-OH-HHC”: it contains no 10-OH-HHC, but CBD, CBN and compounds attributed to isomers of tetrahydrocannabidiol. The authors warn that labels can't be relied on.
ACMD (United Kingdom) · May 2025
The council considers the data on semi-synthetic cannabinoids “preliminary”, often without analytical confirmation, but sufficient to point to a potential public health risk. 10-OH-HHC is on the list of compounds to be controlled.
ANSM · June 2024
In France, cannabinoids derived from the benzo[c]chromene core, the structure shared by THC and HHC, are classed as controlled drugs. Serious effects reported include vomiting, loss of consciousness, seizures, paranoia and a racing heart.
The tetrahydrocannabidiol found by the Japanese study is H4-CBD, a controlled drug in France since June 2024. So a blend sold under a code name can contain something other than what's written on it, including a banned substance.
Reported effects
Delta BZ10 effects: promises, not proof.
Product pages describe a fast onset, pronounced euphoria, deep relaxation and effects “sometimes more intense than THC's”. Some add better sleep or pain relief. None of these claims rests on a study: they're sales pitches and customer reviews.
Two things need saying. First, the product pages contradict each other: the same page can present BZ10 as “less psychoactive than THC” and then as stronger than it. Second, the effects depend on the recipe. A version with muscimol has nothing in common with a version without it: muscimol doesn't act like a cannabinoid, and the ANSM states that its effects can appear between 30 minutes and 2 hours after taking it and last for several days.
So a “Delta BZ10 review” only holds for the exact product that person used. To understand what really makes a product intense, read our article on the strongest CBD.
The rules in France
Is Delta BZ10 legal? No, nobody can say that.
BZ10 isn't a substance: its status is that of its ingredients. And on that front, things have changed in France since most of the articles you'll find online were written.
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, H2-CBD and any substance derived from the benzo[c]chromene core are listed as controlled drugs. CBN is excluded.
6 June 2025
The Conseil d'État, France's highest administrative court, upholds this classification by structural family.
11 July 2026
Muscimol and ibotenic acid are banned from sale, production and use in France.
In practical terms: in France, a BZ10 product that contains muscimol is banned. As for 10-OH-HHC, to our knowledge no ANSM decision cites it by name, but it's a direct derivative of HHC and the 2024 classification targets an entire family: nobody can seriously guarantee you that it falls outside it. The detail on HHC is in our HHC, THC, THCP and Delta-P comparison.
Key takeaway: most of the pages presenting Delta BZ10 as “legal” date from late 2024 or 2025, before the muscimol ban in France. A THC level below 0.3% changes nothing: that threshold applies to the THC in hemp, not to added compounds. The rules move fast.
Before you buy
Why a blend with no recipe is a problem.
- You don't know what you're taking. Three recipes are in circulation, with no proportions. Two “BZ10” products may not share a single active ingredient.
- Compounds that stack up. Mixing an HHC derivative with a substance like muscimol means combining two modes of action with no data at all on how they work together.
- Formats that are hard to dose. Something you swallow kicks in late, which pushes people to take more too soon: gummies are the format the ANSM cites in the muscimol poisonings.
- Labelling you can't verify. Nobody checks the levels shown on the pack.
- A legal risk. In France, holding a product that contains a classified substance is an offence, whatever the label says.
Some sellers pitch it at “regulars who want to go further”. Given the information publicly available, we don't recommend it to anyone. If you already have some: adults only, a very small amount, no mixing with alcohol, never before driving, never during pregnancy or breastfeeding. 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.
Our position
We don't sell BZ10, only Delta-P.
Today Golden High only sells its Delta-P range, based on CBDX, below 0.3% THC and lab-tested. None of our products contains BZ10, muscimol or 10-OH-HHC. Despite the similar names, “Delta BZ10” and “Delta-P” have nothing to do with each other: we explain what the latter is in Delta-P: what it is, effects and legal status.

Your questions
What people ask us about Delta BZ10.
What is Delta BZ10?
A trade name, not a molecule. It refers to a blend of active compounds applied to flowers, resins, e-liquids or gummies, whose advertised composition varies from seller to seller. No scientific study has looked at it.
What does BZ10 contain?
Depending on the shop: 10-OH-HHC, muscimol, CBN and CBC; or 10-OH-HHC, THV-N10 and CBN; or a synthetic “single molecule”. No proportions and no independent analysis have been published.
Is Delta BZ10 legal in France?
Nobody can say so. Any version containing muscimol has been banned in France since 11 July 2026. 10-OH-HHC isn't cited by name by the ANSM, but the classification of 3 June 2024 targets a whole family of cannabinoids by its structure.
What are the effects of Delta BZ10?
Sellers describe a fast onset, euphoria and marked relaxation, sometimes compared with THC. These are marketing statements: nothing has been measured, and the effects depend on the recipe actually used.
How much are Delta BZ10 reviews worth?
Each review only describes one specific product, since the composition changes from shop to shop. They tell you nothing about safety or about what the product really contained.
Is BZ10 CBD?
No. Even when it's sold in a CBD shop, sometimes on a hemp flower, BZ10 refers to added compounds: an HHC derivative and, depending on the version, muscimol, which isn't even a cannabinoid.
Are Delta BZ10 and Delta-P the same thing?
No. Delta-P is the name of the Golden High range, based on CBDX, below 0.3% THC and lab-tested. None of our products contains BZ10.
