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

Delta-8-tetrahydrocannabinol (Δ⁸-THC) has the same formula as Δ⁹-THC, the psychoactive molecule in cannabis. Only the position of one double bond in one of the molecule's rings changes. The two are isomers: same atoms, different arrangement.

The plant makes very little of it. The WHO critical review of THC isomers reports Δ⁹/Δ⁸ ratios ranging from 99.9/0.1 to 98.6/1.2. It adds that the Δ⁸ found in cannabis may simply be a breakdown product of Δ⁹. The delta-8 sold online is therefore manufactured: the same document describes the most common synthesis, cyclising CBD in strong acid.

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

This point is often misunderstood, including by some sellers. French law does not list THCs 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”, along with their esters, ethers and salts. Delta-8 falls into that category without any new text being needed. Internationally, it also sits in Schedule I of the 1971 Convention on Psychotropic Substances, with other THC isomers, according to the same WHO document.

CBD escapes this ban through an exemption. The decree of 30 December 2021 allows 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. The exemption concerns hemp and its extracts, not THC made by synthesis. The fact that the threshold only names Δ⁹ opens no door for Δ⁸: it remains a banned tetrahydrocannabinol.

ANSM classifications have since added other molecules that were not THCs in the strict sense. HHC, HHCO and HHCP have been narcotics since 13 June 2023. H4CBD, H2CBD, HHCPO and THCP followed on 3 June 2024. Our HHC timeline and our page on THCP trace these decisions.

As a narcotic, delta-8 falls under the general penalties. The amounts below are those of the texts in force on 23 September 2026:

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

Because it is made by a chemical reaction, a delta-8 product also contains whatever that reaction leaves behind. A study published in 2022 in Chemical Research in Toxicology analysed 27 delta-8 vape cartridges from 10 brands. None showed an accurate Δ⁸-THC content. Eleven contained undeclared cutting agents. All contained synthesis by-products, including Δ⁹-THC, metals and a previously undescribed cannabinoid.

The United States, where delta-8 was sold freely, has the most complete figures. 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. Among unintentional exposures, 82% affected children. Two thirds of the reports to the FDA followed eating a food product, such as a gummy or a brownie.

In France, ANSES reported in June 2025 several hundred poisonings since early 2024 linked to products sold as CBD but containing other substances: HHC, H4CBD, synthetic cannabinoids, or THC above the legal threshold. Our article on synthetic cannabinoids in CBD covers these cases.

The decree of 13 December 2016 sets the thresholds for roadside testing. All of them target 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. The text does not mention delta-8.

That does not protect a driver at all. The 2022 analyses found Δ⁹-THC in every delta-8 product tested. And article L235-1 of the Highway Code punishes driving after using 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 as soon as use of a narcotic is established, even when the product consumed was sold legally. Our guide to drug testing covers detection windows.

Delta-8 spread in the United States because the federal definition of hemp only capped Δ⁹-THC. 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 this loophole: its ban has covered every tetrahydrocannabinol from the start.

On a label or product page, these signs are enough to rule a product out:

• The words “delta-8”, “Δ8”, “D8”, “HHC”, “H4CBD”, “THCP” or “THC-O”.
• A promised effect: “high”, “euphoric”, “legal buzz”.
• A gummy or cartridge sold “with hemp” without an accessible analysis.

A compliant CBD product promises no psychoactive effect. The certificate of analysis for a batch should show Δ⁹-THC at 0.30% or less: our guide to the certificate of analysis and our laboratory page explain how to read it. To report a suspicious product in France, the DGCCRF's SignalConso platform is open to everyone. If you feel unwell after use, call 15 or a poison centre, and keep the packaging.
