CBD for beginners: 16 questions to settle before buying

1. Is CBD legal in France?

Yes, under conditions. The decree of 30 December 2021 authorises hemp varieties listed in the official catalogues, provided their Δ⁹-THC content stays at or below 0.30%. It also banned the sale of raw flowers and leaves, until the Council of State struck down that ban on 29 December 2022 (decision no. 444887). Flowers and resins have been sold like other hemp products ever since.

2. How much THC is allowed?

The ceiling is 0.30% Δ⁹-THC, and it covers extracts and the products made with them too. The 0.2% figure that still circulates was the old limit, abandoned in 2021. Our article on the legal THC level walks through the calculation and the testing margin.

3. Which cannabinoids are banned?

Several semi-synthetic molecules once marketed as CBD alternatives are now narcotics. ANSM, the French medicines agency, classified HHC, HHCO and HHCP from 13 June 2023, and H4CBD, H2CBD, THCP and other derivatives from 3 June 2024. Whatever the label says, a product that contains them is illegal.

4. Can you buy a CBD oil to swallow?

Not as food. The Ministry of Agriculture restated on 20 May 2026 that foods containing CBD are not authorised under the EU novel food regulation, since their safety has not been demonstrated, and said it is extending controls. The exceptions are hemp seeds, their derivatives such as seed oil, and leaves meant for infusion. Our update on novel food rules tracks the file.

Our article on the legal age for CBD explains that e-liquids come under the rules for vaping products.

5. Does CBD get you high?

No, you will not get the high that THC produces. CBD is still active, though. MILDECA, the French interministerial mission against drugs, writes on its CBD page that it has psychoactive effects "in that it acts on the brain", and that, unlike THC, it causes no dependence. Our article does CBD get you high? explains the difference at receptor level.

6. Is CBD a medicine?

No, with one exception. Epidyolex, the only CBD-based medicine, obtained its EU authorisation on 19 September 2019. Doctors prescribe it from age 2 for three rare epilepsies: Lennox-Gastaut syndrome, Dravet syndrome and tuberous sclerosis complex. Shop products may not claim any therapeutic effect, and MILDECA notes that sellers who make such claims face penalties. Our article on Epidyolex summarises the trials behind it.

7. What effects can you expect?

No French or European authority has validated any effect of shop-bought CBD on sleep, stress or pain. Clinical trials exist, often at medicinal doses well above everyday use. What consumers report, a sense of relaxation for instance, is personal experience. Our review of what clinical studies say separates the measured from the assumed, and our article on feeling nothing explains why some people notice no effect.

8. Who should not use CBD?

EFSA considers that the safety of CBD cannot be established for three groups: people under 25, pregnant or breastfeeding women, and anyone on medical treatment. ANSES, the French food and health safety agency, also proposed on 21 March 2025 classifying CBD as presumed toxic for reproduction, category 1B. The proposal draws on animal studies showing effects on sperm production and fertility, higher mortality around birth and changes in how the nervous system develops. The same caution applies if you are planning a pregnancy.

9. Does CBD interact with medicines?

Yes, and it is documented. CBD is processed by liver enzymes that also break down many medicines. Epidyolex is itself prescribed alongside clobazam, an anti-epileptic drug, and EMA names liver problems as its main safety concern, with liver enzymes monitored. If you are on any treatment, speak to your doctor or pharmacist before trying CBD. Our article on drug interactions lists the known examples.

10. What side effects are known?

The best-described ones come from Epidyolex, so from medicinal doses. According to EMA, the most common are sleepiness, decreased appetite, diarrhoea, fever, tiredness and vomiting. Data are missing for everyday amounts, hence EFSA's caution. Our review of CBD side effects sorts them by dose.

11. How much CBD per day?

EFSA provides the only official benchmark. On 9 February 2026, it published a provisional safety level of 0.0275 mg per kilo of body weight per day, which comes to about 2 mg for an adult of 70 kg. The figure carries an extra margin, because the data on the liver and on the endocrine, nervous and reproductive systems are incomplete.

To work it out, multiply your body weight in kilos by 0.0275.

Two points affect how you read it. The level covers CBD food supplements of at least 98% purity, a format France does not authorise today. And no authority has set a benchmark for inhaled flower or resin, where the CBD actually absorbed depends on the product and the way it is used. The careful approach is still to start small and to avoid raising the amount in pursuit of an effect. Our article on the EFSA reference dose goes through the opinion.

12. Can you drive after taking CBD?

The risk comes from the THC traces in the product. MILDECA warns that a driver who has used only authorised products may still test positive for THC in a saliva or blood sample. On 21 June 2023 (no. 22-85.530), the Court of Cassation ruled that the legal sale of these products changes nothing: the offence stands whatever the dose. Article L235-1 of the Highway Code sets the penalty at three years in prison and a 9,000 € fine. Our guide to saliva testing explains how the tests work.

13. Can you travel with CBD?

A compliant product can travel with you inside France. Abroad, the law of each transit and destination country applies, and it is often stricter. Our article on flying with CBD goes through the destinations.

14. Which format should you start with?

Three families are legal: flower, resin and cosmetics. Flower is the easiest to read, since it states a variety and a level. Resin is more concentrated, and cosmetics go on the skin. Burning flower or resin produces smoke, whatever the plant: our article on smoking hemp sets out what the law and the data say, and the one on vaporisation presents the alternative. A small amount is enough the first time: in the catalogue, the CBD flower product pages offer formats from 2 g.

15. How do you check that a product is compliant?

Ask for the batch certificate of analysis and check four lines. The batch number must match the product, and Δ⁹-THC must be 0.30% or less. The CBD level should sit close to the label. Where the laboratory tested for banned cannabinoids, none should appear. Our guide to reading a certificate of analysis covers each section, and the laboratory page describes the measurement methods.

16. How much does a first purchase cost?

The price per gram varies a lot with format and quantity, and it falls clearly at higher purchase tiers. The real warning sign is a price with no batch analysis behind it. Our article on CBD prices in France in 2026 gives the ranges per gram.
