Cannabis and driving: what Spanish traffic law says
How roadside drug checks work in Spain, what penalty they carry, and when the matter stops being a fine and becomes a criminal offence.
August 14, 2026
Spanish road traffic law penalises the presence of drugs in the body of the person driving, without any need for the driving itself to be visibly impaired. It is a very serious infringement, punished with a fine of 1,000 euros and the deduction of 6 points from the licence. Only when it is also established that the driver was bajo la influencia (under the influence) of the substance does the matter leave administrative ground and come under Article 379.2 of the Spanish Criminal Code.
Zero tolerance: what it actually means
The consolidated text of the Spanish law on traffic, motor vehicle circulation and road safety prohibits driving with drugs present in the body. The difference from alcohol is substantial: for alcohol there are maximum levels expressed as figures, whereas for drugs there is no legal threshold. Any confirmed presence is enough for a charge to be issued.
Hence the phrase "zero tolerance", which is often misread. It does not mean the law presumes the driver is incapacitated, but precisely the opposite: the legislator chose not to argue about the degree of impairment through the administrative route. Feeling subjectively fine is not an argument against a positive result, because the conduct being penalised is not "driving badly" but driving with the substance present.
The rule itself excludes substances used under medical prescription and for a therapeutic purpose, provided the driver is in a condition to handle the vehicle with the care required. It is a narrow exception, tied to a specific prescription, and proving it falls on whoever invokes it. It is worth remembering that a cannabis association is not a therapeutic channel and issues no prescriptions of any kind: on what an association is and is not, the reference page on cannabis clubs goes into detail.
The administrative prohibition reaches anyone driving any vehicle. The criminal route, by contrast, is drafted expressly for motor vehicles and mopeds.
How the check works: screening and laboratory confirmation
A roadside drug check is structured in two stages, with an additional safeguard for the person being checked. Officers may carry it out at preventive checkpoints, after an accident, where an infringement has been committed or where they observe compatible symptoms.
The counter-test can only be requested during the stop. Once the charge sheet has been signed and the journey resumed, that route is closed: it is a line of defence that cannot be recovered afterwards.
Refusing to undergo the legally established tests is defined as a criminal offence in Article 383 of the Criminal Code, with prison sentences of six months to one year and disqualification from driving motor vehicles and mopeds for more than one year and up to four years. In other words, refusal leads to criminal proceedings even if the test result would have been negative.
The administrative penalty: amount and points
The infringement is classified as very serious. Alongside the fine comes the deduction of 6 points from the licence balance, which in the general case starts at twelve. Exhausting the balance means the licence loses validity, and recovering it requires a re-education course and a knowledge test. Courses exist for partial recovery of the balance, but they can only be taken at limited intervals.
As with other traffic penalties, voluntary payment within the set period halves the amount. That reduction has a trade-off: it entails waiving the right to submit representations and closes the procedure, so it ends any discussion of the substance. The points, by contrast, are not reduced by paying early.
Officers may immobilise the vehicle if there is no other qualified driver able to take charge of it. Processing falls to the Dirección General de Tráfico (the national traffic authority) or, in territories where the power has been transferred, to the corresponding regional body. This penalty is administrative and creates no criminal record, as is also the case with fines for consumption or possession in public places, although the amount and the consequences for the licence are very different.
When Article 379.2 turns this into a criminal offence
Article 379.2 of the Criminal Code punishes anyone who drives a motor vehicle or moped under the influence of toxic drugs, narcotics or psychotropic substances. The difference from the administrative infringement lies in those three words: "under the influence". Here presence is not enough; it must be established that the ability to drive was affected.
That is established through elements recorded in the police report: the manner of driving observed, the external signs noted by the officers, the information gathered at the scene and the analytical result. Unlike alcohol, for drugs there is no objective level above which the offence is taken as committed regardless of the driver's state.
| Aspect | Administrative route | Criminal route (Art. 379.2) |
|---|---|---|
| What is penalised | The presence of the substance in the body | Driving affected by the substance |
| What must be proved | A confirmed analytical result | In addition, the influence on the ability to drive |
| Main consequence | A fine of 1,000 € and 6 points | Prison, a fine or community service, and disqualification from driving |
| Criminal record | No | Yes, if convicted |
| Who decides | The traffic administration | A court |
The penalties under Article 379.2 are three to six months' imprisonment, or a fine of six to twelve months, or community service of thirty-one to ninety days. In any of the three cases, disqualification from driving motor vehicles and mopeds for more than one year and up to four years is imposed as well. That last effect is usually the one that weighs most heavily on the daily life of the person convicted.
How long it can be detected
There is no generally valid answer, and this article does not offer one. Detection windows vary with the frequency of consumption, the quantity, individual metabolism, the type of sample and the threshold applied by the device or the laboratory. Two people in apparently the same situation can produce different results.
Something more basic can be said: detection and perceived effects are not measured by the same yardstick. The check does not assess how the driver feels, but whether the substance shows up in the sample analysed. That is why a subjective sensation does not anticipate the result of a test, and no equivalence between the two can be taken as sound.
This article gives no waiting times before driving, no elimination tables and no methods for altering the result of a test. No figure circulating in forums works as a legal guarantee, and tampering with a sample or refusing a check makes the situation worse rather than resolving it. The only course compatible with the rule is not to drive after consumption.
What to do if you test positive
Traffic penalty proceedings have short deadlines and several stages. Knowing them prevents losing rights through inaction. Where the matter is referred to the criminal route, the path is different and requires legal representation from the outset.
What follows describes the procedure in general terms, not anyone's particular situation. The deadlines, the competent body and the options for appeal depend on each file and on the administration processing it, and the same step may be resolved differently according to what the police report contains; for an individual case the sensible course is to consult a legal professional. Nor is this text a consumption or growing guide, and it contains no indications of that nature.
It is the only moment at which it can be asked for. It is recorded on the charge sheet and its result prevails if it contradicts the earlier one.
Date, time, place, identification of the officers, device used and the facts described. Relevant errors in these details are the basis of many representations.
They are addressed to the investigating body named in the notification, with whatever evidence you wish to provide. Paying early at the reduced amount closes off this possibility.
The appeal is filed with the same body that made the decision, within the period stated in the decision itself.
Once the administrative route is exhausted, review falls to the courts. This is the stage where professional advice weighs most.
If what arrives is a court summons rather than an administrative charge, the position changes entirely: there is a right to a lawyer, a right not to incriminate oneself and a right to propose evidence, and the decisions taken in the first hours shape the rest of the proceedings.
A cannabis association works as a closed circuit of consumption among members inside its own premises. That logic ends where the premises end: anything taken out of the building falls outside that cover, and carrying it in a vehicle is assessed by different criteria and with its own consequences. The full reasoning is explained in what a cannabis social club is and in the general legal framework for cannabis in Spain.
Frequently asked questions
Can a product containing CBD produce a positive result?
It cannot be ruled out. Checks look for THC, and hemp products contain traces of that substance in proportions that vary by product and by batch. The administrative rule attends to the detected presence of the controlled substance, not to the label on the product consumed.
Does having a medical prescription help?
The law excludes substances used under medical prescription for a therapeutic purpose, provided the driver is in a condition to handle the vehicle with due care. It is an exception tied to a specific and provable prescription, not a general exemption. A cannabis association plays no part in that area and issues no document with any healthcare value.
Can the check be refused?
No. Refusing to undergo the tests is defined as a criminal offence in Article 383 of the Criminal Code, carrying imprisonment and disqualification from driving. Requesting the counter-test is a different matter: that is a right of the person checked and forms part of the procedure itself.
Does a drug-driving fine leave a criminal record?
An administrative penalty creates no criminal record: it has financial effects and effects on the points balance. A record appears only where there is a criminal conviction, for driving under the influence or for refusing the tests.
