Is delta-8 THC legal in France? No, it is a narcotic

Delta-8-tetrahydrocannabinol (Δ⁸-THC) shares its formula with Δ⁹-THC, the psychoactive molecule in cannabis. The only change is the position of a double bond in one of the molecule's rings. They are isomers: the same atoms, arranged differently.

The plant produces very little of it. The WHO critical review of THC isomers reports Δ⁹/Δ⁸ ratios from 99.9/0.1 to 98.6/1.2, and suggests that the Δ⁸ found in cannabis may simply be a breakdown product of Δ⁹. The delta-8 sold online is therefore made in a lab. The same document describes the most common synthesis, which cyclises CBD in strong acid.

Its effects are of the same kind as those of THC. According to the WHO, the few human trials described an intoxication “similar in quality” to that of Δ⁹-THC, though weaker. A delta-8 product is psychoactive, which puts it in a different category from CBD.

The European Food Safety Authority (EFSA) put a figure on the gap in November 2025: based on a clinical study, Δ⁹-THC is estimated to be 1 to 1.4 times as potent as Δ⁸-THC. To be safe, it counts the two molecules as equivalent and applies the same acute reference dose to their sum in food.

Some sellers get this point wrong too. French law has no list of THCs taken one by one: article R5132-86 of the Public Health Code bans the production, sale, possession and use of cannabis and of “tetrahydrocannabinols, natural or synthetic”, together with their esters, ethers and salts. Delta-8 falls within that category without any new text. Internationally, the same WHO document places it in Schedule I of the 1971 Convention on Psychotropic Substances, alongside other THC isomers.

CBD stays outside the ban thanks to an exemption. The decree of 30 December 2021 authorises Cannabis sativa L. varieties whose delta-9-THC content does not exceed 0.30%, and caps extracts and the products containing them at the same level. That exemption covers hemp and its extracts; THC made by synthesis stays outside it. The threshold names only Δ⁹, which gives Δ⁸ no opening: it remains a banned tetrahydrocannabinol.

Later ANSM classifications added other molecules that were not, strictly speaking, THCs. HHC, HHCO and HHCP have been narcotics since 13 June 2023, and H4CBD, H2CBD, HHCPO and THCP were added on 3 June 2024. These decisions are traced in our HHC timeline and our page on THCP.

As a narcotic, delta-8 is subject to the general penalties. The amounts below come from the texts in force on 23 September 2026:

Law No. 2026-798, in force since 20 August 2026, raised the fixed fine from €200 to €500. A shop selling delta-8 gummies or cartridges is exposed to the penalties of article 222-37, whatever the word “hemp” on the packaging.

Delta-8 comes out of a chemical reaction, and the product also carries whatever that reaction leaves behind. A study published in 2022 in Chemical Research in Toxicology analysed 27 delta-8 vape cartridges from 10 brands. Not one showed an accurate Δ⁸-THC content. Eleven contained undeclared cutting agents, and all contained synthesis by-products, among them Δ⁹-THC, metals and a cannabinoid never described before.

The most complete figures come from the United States, where delta-8 was sold freely. The FDA recorded 104 adverse event reports between December 2020 and February 2022. From January 2021 to February 2022, US poison centres logged 2,362 delta-8 exposure cases, 41% of them involving under-18s, and 82% of unintentional exposures concerned children. Two thirds of the reports to the FDA followed eating a food product such as a gummy or a brownie.

ANSES reported in June 2025 several hundred poisonings in France since early 2024, linked to products sold as CBD that contained other substances: HHC, H4CBD, synthetic cannabinoids, or THC above the legal threshold. These cases are covered in our article on synthetic cannabinoids in CBD.

Roadside testing thresholds are set by the decree of 13 December 2016, and every one of them targets 9-tetrahydrocannabinol: 15 ng/ml of saliva for the roadside test, 1 ng/ml for the confirmatory saliva analysis, 0.5 ng/ml in blood. Delta-8 is not mentioned.

This gives a driver no protection. The 2022 analyses found Δ⁹-THC in every delta-8 product tested, and article L235-1 of the Highway Code punishes driving after use of any substance “classified as a narcotic”. On 21 June 2023 (No. 22-85.530), the Court of Cassation ruled that the offence is made out once use of a narcotic is established, even if the product consumed was sold legally. Detection windows are covered in our guide to drug testing.

Delta-8 spread in the United States through a gap: the federal definition of hemp capped Δ⁹-THC alone. A federal law passed in November 2025 switches to “total THC” and excludes from hemp any finished product with more than 0.4 mg of total THC per container. It is due to apply from late 2026. France never had that gap, since its ban has covered every tetrahydrocannabinol from the outset.

On a label or product page, any one of these signs rules a product out:

• Any of the words “delta-8”, “Δ8”, “D8”, “HHC”, “H4CBD”, “THCP” or “THC-O”.
• A promised effect, such as “high”, “euphoric” or “legal buzz”.
• A gummy or cartridge sold “with hemp” with no analysis available to read.

A compliant CBD product makes no promise of a psychoactive effect, and a batch certificate of analysis should show Δ⁹-THC at 0.30% or less. How to read one is explained in our guide to the certificate of analysis and on our laboratory page. In France, anyone can report a suspicious product on the DGCCRF's SignalConso platform. If you feel unwell after use, call 15 or a poison centre and keep the packaging.
