- First described
- Signalée en 1972 par van Ginneken, Vree, Breimer, Thijssen et van Rossum, qui l'ont détectée dans du haschich par chromatographie en phase gazeuse couplée à la spectrométrie de masse, dans le travail présenté au symposium GC-MS de l'île d'Elbe qui décrivait aussi le cannabinodiol. Seul l'homologue en C5, le cannabinodiol, a ensuite été confirmé par isolement et synthèse, en 1977 par Lousberg et ses collègues ; l'homologue propyle n'a jamais fait l'objet d'une caractérisation indépendante par RMN.
- Origin
- A trace constituent of aged cannabis resins. CBND-C3 rests on a single GC-MS detection in 1972 and has never been isolated in pure form from the plant; no quantified content has been published since. The review by Radwan and colleagues (2021) lists only two CBND-type cannabinoids among the one hundred and twenty-five recorded, this one included. It is therefore more accurate to describe it as an ageing product encountered in trace amounts than as a biosynthesised constituent of hemp.

In plain terms
Cannabinodivarin is a very rare cannabinoid, spotted only once, in 1972, in old hashish. It is the short-chain variant of cannabinodiol, a molecule that appears when cannabidiol ages under the effect of light and air. What it does in the body remains unknown, because no study has been carried out on it.

Pharmacology
CBND-C3 belongs to the cannabinodiol subfamily, the smallest of the eleven classes of phytocannabinoids recorded in the review by Radwan and colleagues, which has only two members. Aromatisation of the terpenic ring turns the cannabidivarin skeleton into a biphenyl and makes the molecule lose the three-dimensional geometry on which recognition by the cannabinoid receptors rests. Pharmacologically, the file is empty in the strict sense: no affinity constant at CB1 or CB2, no screening at TRPV1, GPR55, PPARγ or 5-HT1A, no entry in ChEBI or in ChEMBL, no publication indexed in PubMed under this name. Human data are lacking, and animal data are missing too. The C5 homologue, cannabinodiol, was at least isolated, synthesised and chemically related to cannabinol in 1977, which is not the case for the propyl homologue. Any claim of an effect, sedative, analgesic or otherwise, would here be an extrapolation without experimental support.

Biosynthetic pathway
No enzymatic pathway is described. The CBND skeleton results from the non-enzymatic aromatisation of the terpenic ring of CBD-type cannabinoids, under the effect of light, air and ageing, a mechanism documented for the C5 homologue. For the propyl chain, the expected precursor is cannabidivarin, itself arising from the divarinic pathway of hemp by way of cannabigerovarinic acid. This lineage remains a structural inference; it has not been demonstrated experimentally for CBND-C3.
Legal framework
France
In France, cannabinodivarin is named in no annex of the decree of 22 February 1990 setting the list of substances classified as narcotics. The generic clause of annex IV covers the tetrahydrocannabinols, their esters, ethers and salts as well as the salts of the aforementioned derivatives: this molecule is neither a tetrahydrocannabinol, nor an ester, an ether or a salt of tetrahydrocannabinol, so neither is it caught by that clause. It falls within the usual situation of the non-THC natural cannabinoids, namely the absence of scheduling. The applicable framework remains that of the plant and its extracts, article R. 5132-86 of the public health code and the decree of 30 December 2021, whose provision prohibiting the sale to consumers of flowers and leaves from authorised varieties assaying less than 0.3% THC was annulled by the Conseil d'État on 29 December 2022.
European Union
No Union instrument names cannabinodivarin. Nor does it appear in the international conventions of 1961 and 1971, which cover cannabis, resin and the tetrahydrocannabinols, or among the substances monitored by the European agency EUDA under the heading of new psychoactive substances. On the food side, the European Commission considers Cannabis sativa extracts and the products containing cannabinoids derived from them to be novel foods within the meaning of Regulation (EU) 2015/2283, and no cannabinoid has received authorisation on that basis to date, EFSA having concluded in 2025 that the safety of synthetic cannabidiol could not be established on the state of the dossier. National regimes remain heterogeneous from one member state to another.

- Status
- Unscheduled
Cannabinoïde de type CBND, c'est-à-dire un biphényle entièrement aromatisé : deux noyaux aromatiques reliés directement, l'un portant la fonction résorcinol et une chaîne latérale propyle, l'autre un groupe isopropényle et un méthyle. C'est la forme aromatisée de la cannabidivarine, et la forme à cycle ouvert de la cannabivarine ; elle ne possède pas le noyau benzo[c]chromène qui caractérise les tétrahydrocannabinols.
Pharmacokinetics
Aucune étude d'absorption, de distribution ou d'élimination n'a été conduite sur le CBND-C3, ni chez l'animal ni chez l'être humain. Les données humaines manquent entièrement.
Metabolism
Aucune voie métabolique n'a été identifiée et aucun métabolite n'a été décrit. Aucun travail sur microsomes hépatiques ou sur les cytochromes P450 ne porte sur cette molécule.
Toxicology and risks
Aucune étude de toxicité, aucun test de génotoxicité et aucun signalement clinique ne concernent le CBND-C3. Cette absence de donnée ne vaut pas démonstration d'innocuité, elle signifie seulement que la question n'a jamais été instruite.
Detection and analysis
La seule approche documentée est celle de la détection d'origine, la chromatographie en phase gazeuse couplée à la spectrométrie de masse appliquée à un extrait de résine. Il n'existe ni matériau de référence certifié ni méthode validée pour cette molécule, et aucun laboratoire de contrôle ne la recherche en routine dans les panels cannabinoïdes. Sa masse moléculaire, supérieure de deux unités à celle de la cannabivarine, la distingue en principe de cette dernière en spectrométrie de masse, mais aucune procédure forensique publiée ne s'appuie sur ce critère.
