CBN + THC gummies: why they are banned in France

Gummies sold for sleep in the United States combine a few milligrams of CBN (cannabinol) with a few milligrams of THC. In France, two distinct rules apply to them.

First rule: THC is a narcotic. Hemp benefits from an exemption set by the decree of 30 December 2021: varieties listed in the official catalogues, no more than 0.30% Δ⁹-THC in the plant and in extracts. A product above that threshold is a narcotic. The ANSM and Anses repeat this in their press release of 19 June 2025: selling, buying and consuming it are prohibited, whatever the form. Our article on the legal THC level explains this threshold.

Second rule: food. On 20 May 2026, the Ministry of Agriculture declared foods enriched with cannabinoid extracts, THC or other narcotic molecules illegal, food supplements included. The legal basis is the EU novel food regulation: none of these ingredients has been authorised under it.

This second rule matters more than it seems. Take a 4 g gummy dosed at 5 mg of THC: THC makes up 0.125% of its mass, below the 0.30% threshold. The percentage alone would not be enough to bring it under narcotics law. The ban on enriched foods applies whatever the content. Our article on CBD gummies follows the effect of this rule on a very common format.

The 2018 US farm law, known as the Farm Bill, defines hemp by a maximum of 0.3% delta-9-THC on a dry weight basis. Manufacturers applied that percentage to finished products. On a 4 g gummy, 0.3% of the weight is 12 mg of THC: enough for a psychoactive effect while respecting the letter of the law. Drinks, gummies and THCA-rich products were sold on that basis.

That gap is closing. A law signed at the end of 2025 redefines hemp and limits finished products to 0.4 mg of total THC per container, THCA included. Planned for 12 November 2026, its entry into force was pushed back to 11 December 2026 by a law signed on 2 September 2026. Cannabinoids that the plant does not produce naturally lose their status from 12 November.

CBN forms when THC oxidises. It is not on any narcotics list. When it classified H4CBD, THCP and other derivatives from 3 June 2024, the ANSM even excluded CBN and CBNA by name from its decision. The same decision leaves THCA permitted in hemp whose THC stays below 0.3%.

CBN should not be confused with HHC, classified as a narcotic since 13 June 2023, or with THCP: our HHC timeline traces these decisions. Our article CBD vs CBN compares the chemistry of the two molecules.

Not being a narcotic does not make CBN saleable in every form. In a gummy or a capsule, it falls under the ban on enriched foods of 20 May 2026, with or without THC.

CBN itself has been little studied in humans. The larger of the two controlled trials published, which appeared in 2024, followed 293 adults for seven nights at 20 mg a day. That is too little to establish a long-term safety profile, and nobody knows what repeated use over months does. Our article on CBN in France summarises both published trials.

The documented risk comes from elsewhere. In their June 2025 press release, the ANSM and Anses report several hundred poisonings since early 2024 in people who had used products presented as containing CBD. In most cases, THC or synthetic cannabinoids were the cause. The agencies cite a study carried out in 2023 by the addiction-monitoring centres of Lyon, Paris and Montpellier: 8 products out of 10 showed a CBD content different from the label.

Reported symptoms range from drowsiness and nausea to rapid heartbeat, hallucinations, loss of consciousness and seizures. The agencies add two warnings: products labelled "strong" carry the highest risk, and CBD taken with certain medicines can reduce their effectiveness or increase their side effects. An imported, unchecked gummy combines these risks. Swallowed THC adds its own: according to a 2003 pharmacology review, its psychoactive effects start 30 to 90 minutes after ingestion and last 4 to 12 hours depending on the dose, a delay that can lead people to take another gummy too soon. Our article on THC gummies details this timing.

Finally, the road. The Cour de cassation ruled on 21 June 2023 that driving after using narcotics is an offence whatever the dose. The penalty is 3 years in prison and a €9,000 fine, with 6 points removed from the licence, according to the service-public.fr page on drug driving.

Ordering these gummies from a US website means bringing a banned product into France, and a narcotic as soon as the THC falls outside the authorised hemp framework. Article 222-36 of the French Penal Code punishes the illegal import of narcotics with 10 years in prison and a €7,500,000 fine. The text makes no exception for personal use. A seller based in France falls under article 222-37, which sets the same penalties for offering, supplying and possessing narcotics.

Legality in the country of origin changes nothing. A gummy sold freely in a US state is still banned when it arrives in France. Our article on ingested THC in France covers drinks and oils.

Flowers and resins from authorised hemp varieties, with no more than 0.30% Δ⁹-THC, remain on sale as long as they are not presented as food. So do CBD cosmetics. None of these products may claim an effect on sleep: such a claim would push it into the medicines regime. For persistent insomnia, the French National Authority for Health recommends sleep hygiene and cognitive behavioural therapy before any medication, with a doctor.
