CBD and Driving: What the Law Really Says
Short answer: in France, the rule is zero tolerance. Article L235-1 of the French Highway Code makes it an offence simply to drive after using narcotics, as soon as a saliva or blood test reveals the presence of THC — whatever the dose. Yet even a perfectly legal CBD product (THC < 0.3%) can leave detectable traces of THC in a saliva test. France's Court of Cassation confirmed this on 21 June 2023: the legal origin of the THC detected is not a valid defence. In practice, consuming CBD flowers or resins and then getting behind the wheel exposes you to a real risk of prosecution. Our position is clear and unambiguous: as a precaution, do not drive after consuming CBD, and keep it for times when you will not be driving. Here is why, point by point.
Zero tolerance: what Article L235-1 of the Highway Code says
Article L235-1 of the French Highway Code (available on legifrance.gouv.fr) punishes "driving after using substances or plants classified as narcotics", once that use is established by a blood or saliva test. THC, the psychoactive molecule in cannabis, is classified as a narcotic under the French Public Health Code (Article L5132-7). The essential point: unlike alcohol, there is no "permitted" level. The threshold mentioned in the technical rules governing the tests is merely a detection threshold for the devices, not a legal tolerance threshold. In other words, the slightest trace of THC detected is enough to constitute the offence, even if you feel no effect and have never consumed illegal cannabis.
The Court of Cassation ruling of 21 June 2023
The question "does legal CBD protect you from prosecution?" was settled by the Court of Cassation (Criminal Chamber, 21 June 2023, appeal no. 22-85.530, published in the bulletin, available on legifrance.gouv.fr). The Court held that Article L235-1 punishes driving after narcotics use "whatever the level" of substance detected, including when it is below the regulatory detection threshold. It made clear that the authorisation to market CBD products containing less than 0.3% THC does not preclude the application of road traffic law. In plain terms: saying "it was CBD bought legally in a shop" is not an admissible defence if the test reveals THC. This case law has been consistent ever since, and the lower courts apply it.
Why a legal CBD product can trigger a positive test
CBD products compliant with the European framework — flowers, resins, full-spectrum oils — may legally contain up to 0.3% THC. That is very little, but it is not zero. The saliva test used at roadside checks is binary: it detects the presence of THC without distinguishing whether it comes from an illegal joint or from a legally purchased CBD flower. Detection time varies widely depending on the method of consumption (inhalation carries more exposure than sublingual oil), frequency of use, individual metabolism and the sensitivity of the test. No one can therefore guarantee a "safe" delay after which driving would be risk-free. And let us be clear: there is no reliable trick to "pass" a test — and trying to circumvent a roadside screening is neither possible nor acceptable. The only strategy that works is to keep consumption and driving completely separate.
The penalties, toughened in 2025
Law no. 2025-622 of 9 July 2025 increased the penalties. Driving after narcotics use is now punishable by 3 years' imprisonment and a €9,000 fine, with 6 points deducted from the licence and possible suspension or cancellation. Where alcohol is also involved, the penalties rise to 5 years and €15,000, with confiscation of the vehicle unless the court specifically decides otherwise. Refusing to undergo testing is itself an offence carrying comparable penalties. Add the practical consequences: vehicle immobilisation, higher insurance premiums, and potentially void cover in the event of an accident. Against all that, the few hours "saved" by driving after consuming count for nothing.
Our recommendations: caution, plainly stated
We sell CBD, and that is precisely why we owe you complete transparency on this subject. Our advice: do not drive after consuming CBD flowers or resins — keep them for evenings at home, weekends without travel, moments when you do not need to take the wheel. Also bear in mind that CBD can cause drowsiness in some people: even without THC, full alertness at the wheel is non-negotiable. Isolate-based products labelled "THC 0%" reduce the risk of a positive test, but no serious seller can guarantee you a negative test 100% of the time. When in doubt, abstain: it is the only rule without exception. To choose lab-tested products with their certificates of analysis, browse our best sellers.
What about elsewhere in Europe?
France is not an isolated case, but approaches differ: some countries apply zero tolerance as it does, while others set THC blood thresholds below which driving is not penalised, at widely varying levels. If you drive abroad, check the rules of the country you are travelling through before you leave — and by default apply the strictest rule. For a full country-by-country overview of the status of CBD, see our CBD legality and delivery hub for Europe, as well as our dedicated guides such as CBD in Germany or in Spain.
FAQ — CBD and driving
Can you drive after consuming CBD?
We advise against it. In France, zero tolerance applies to THC behind the wheel, and even a legal CBD product can leave detectable traces. The safest course is not to drive after consuming, especially flowers or resins.
Does the saliva test detect CBD?
CBD itself is not what is screened for: it is not classified as a narcotic. It is the traces of THC, present in many compliant CBD products (up to 0.3%), that can make the test positive.
What do you risk if you test positive?
Since the law of 9 July 2025: up to 3 years' imprisonment, a €9,000 fine, 6 points deducted and suspension or cancellation of your licence. Penalties rise to 5 years and €15,000 where alcohol is also involved.
Does a legal "THC < 0.3%" product protect you from a penalty?
No. The Court of Cassation ruled on 21 June 2023 that the legal origin of the THC detected is not a defence: the offence is constituted as soon as a test reveals THC, whatever the dose.
How long should you wait before driving again?
There is no guaranteed delay: detection time depends on the product, the method of consumption, frequency of use and metabolism. The only reliable approach is to keep consumption and driving times separate.
Are the rules the same across Europe?
No. Some countries apply zero tolerance, others use THC blood thresholds. Check the rules before driving abroad and see our legality hub for the country-by-country status of CBD.
