1. The legal basis: what the "Gag Law" says about public consumption
The starting point is Article 36.16 of Organic Law 4/2015 on the Protection of Public Safety (known as the "Ley Mordaza" or "Gag Law"), which classifies as a serious infraction:
"The illicit consumption or possession of toxic drugs, narcotics or psychotropic substances, even if not intended for trafficking, in places, roads, public establishments or public transport, as well as abandoning the instruments or other items used for this purpose in said places."
The amounts (Article 39.1 LOPSC): serious infraction, from €601 to €30,000, graded in tiers (minimum €601–10,400, medium €10,401–20,200, maximum €20,201–30,000). In administrative practice, this type of infraction is usually penalized at the minimum tier, though this is a pattern observed by law firms, not a figure set by law. Serious infractions expire after one year, and penalties already imposed expire after two years.
2. The parked vehicle: the 2025 Instruction that changed things
This is the point that has changed most recently, and where it's important to be precise about what is settled law and what is recent, disputed administrative criteria.
Instruction No. 7/2025, of May 7, from the Secretariat of State for Security (Ministry of the Interior), addressed to the National Police and Civil Guard, establishes that consuming or possessing drugs inside a private vehicle used exclusively as a means of transport and parked, not intended for trafficking, "cannot be classified under any of the administrative infractions described" by the LOPSC. The Instruction relies on the principle of legal specificity (Art. 25 of the Spanish Constitution) and on Supreme Court rulings (STS 1317/1999 and STS 569/2013) that recognize the vehicle has "a certain degree of privacy," as well as the doctrine of "reasonable expectation of privacy" (STC 170/2013). There's also a specific judicial precedent: the Administrative Court No. 2 of Jaén annulled a €601 fine in March 2022 for hashish found in a vehicle, ruling that its interior does not equate to a "public place."
This is not a law passed by Parliament nor a settled Supreme Court doctrine on the substance of Article 36.16 — it's an internal administrative directive. Vicente Magro, a magistrate of the Supreme Court's Second (Criminal) Chamber, has publicly criticized it, arguing that a vehicle parked on a public road should indeed be considered a "public place" for these purposes, and that the 1999 ruling the Instruction relies on is outdated. According to press reports (not confirmed by an official statement of their own), the DGT (Spain's traffic authority) and police unions have also expressed rejection. As far as can be verified, there's no Circular from the State Attorney General's Office on this specific matter. Honest conclusion: current operational practice tends not to penalize consumption in a parked vehicle without indications of trafficking, but it's a recent and contested criterion, not a closed legal guarantee.
3. Driving: road safety, criminal offense and checkpoint protocol
Once the vehicle goes from parked to moving, the analysis changes completely: it's no longer about whether it's a "public place" for LOPSC purposes — instead, road safety law comes into play, which can be either an administrative infraction or a criminal offense.
"The same penalties shall apply to anyone who drives a motor vehicle or moped under the influence of toxic drugs, narcotics, psychotropic substances..." The penalties: 3 to 6 months in prison, or a fine of 6 to 12 months, or 31 to 90 days of community service, and in all cases, loss of the right to drive for 1 to 4 years. An important legal point noted by doctrine and case law: unlike alcohol (which has objective limits that are sufficient on their own), the drug offense requires proving actual influence on driving — mere analytical detection of the substance is not enough.
The official roadside checkpoint protocol (according to the DGT): the driver is informed of the obligation to undergo the test; a saliva screening sample is taken; if positive, a second sample is sent to a lab for confirmation (the driver cannot continue driving in the meantime); the driver can request a contrasting blood test, at their own expense if it comes back positive. Refusing the test is a standalone offense (Article 383 Criminal Code): 6 months to 1 year in prison and loss of license for 1 to 4 years.
4. Why there's no numeric THC limit like there is for alcohol
Article 14 of Royal Legislative Decree 6/2015 (Traffic and Road Safety Law) prohibits driving with "presence of drugs in the body," without setting a quantitative threshold — unlike alcohol, which does have exact numeric limits (0.25 mg/l in breath for general drivers, stricter for new drivers and professionals; 0.60 mg/l breath or 1.2 g/l blood for the criminal offense).
A meta-analysis from the University of Sydney (Lambert Initiative, Neuroscience & Biobehavioral Reviews, 2021, 28 studies) concluded that THC concentrations in blood and oral fluid are "relatively poor or inconsistent indicators" of actual driving impairment, and that in habitual users there's no reliable relationship between THC concentration and driving performance. It's precisely this lack of a reliable correlation that explains why lawmakers — in Spain and much of Europe — haven't set a quantitative threshold equivalent to that for alcohol.
Administratively (non-criminal), driving with the presence of drugs is a very serious infraction (Article 77.c of RDL 6/2015): a fine of €1,000 (€500 with prompt payment) and loss of 6 points from the license. Refusing the test is also a very serious infraction on this route.
In the July 2025 campaign, 5,854 roadside drug tests were carried out, with 2,248 positive screenings, of which 1,634 corresponded to cannabis. According to Civil Guard Traffic data, checkpoints rose from 123,211 in 2021 to 144,346 in 2025 (a record), and final penalties from 41,067 to 70,717 over the same period. According to the latest report from the National Institute of Toxicology (2025), of 894 deceased drivers analyzed in accidents, cannabis was present in 72 cases.
5. The camper van: is it legally a "home"?
Here it's important to carefully distinguish two different legal questions, because they're constantly confused: whether the camper van is a "home" (which protects against police searches without a warrant) is not the same as whether consumption inside it is exempt from penalty.
The Supreme Court (STS 5761/1995) recognized that a caravan where a person has established their residence, even if provisional, is protected by Article 18.2 of the Constitution (inviolability of the home), distinguishing the living area (protected) from the driving area (not protected). STS 1165/2009 established the test still cited today: that the habitable part has the essentials to constitute a dwelling (bedroom, kitchen, bathroom) and that it's actually used as such. A later ruling (STSJ Extremadura 8/2017) clarified that neither the location nor the fact of being in motion alone alters this condition — what's decisive is actual habitability and effective use.
The "home" protection regulates police entry and search without a judicial warrant — no case law has been located that directly connects a camper van's home status with an automatic exemption from a penalty for drug consumption. The penalty exemption for parked vehicles we saw in point 2 comes from Instruction 7/2025 on the concept of "public place" under Article 36.16 LOPSC — a different legal reasoning (about legal specificity, not home inviolability). Being a "home" protects against warrantless searches, but doesn't exempt from other regulations or turn the interior into a zone free of any legal regulation.

|---|---|---|---|
| Administrative (LOPSC) | Consumption/possession in a public place, road or public transport | €601–30,000 (serious) | Art. 36.16 and 39.1 LOPSC |
| Administrative (traffic) | Driving with presence of drugs | €1,000 (€500 prompt payment) + 6 points | Art. 77.c and 80 RDL 6/2015 |
| Administrative (traffic) | Refusing the detection test | Very serious infraction | Art. 77.d RDL 6/2015 |

| Criminal | Refusing tests after being asked | Prison 6 months-1 year + license loss 1-4 years | Art. 383 Criminal Code |
7. Myths evaluated one by one
- "If I'm parked in my car they can't do anything to me": nuanced, not an absolute guarantee. There's currently an official Instruction ordering no penalty for parked vehicles without indications of trafficking, but it's a recent administrative criterion (May 2025), not settled law, and it's publicly disputed by a Supreme Court magistrate. If there are indications of trafficking or the vehicle starts moving, the analysis changes completely.
- "In my camper van, since it's my home, I can do whatever I want": false as stated. Being a home protects against police searches without a warrant, but no located case law connects this with an automatic exemption from a consumption penalty, and it certainly doesn't exempt from other rules (like road safety ones if it's moving).
- "The saliva test only comes back positive if you're high at the moment": false, with nuances by user type. In occasional users, THC is usually eliminated from saliva in under 24 hours. In habitual users, a controlled study detected THC in saliva up to 48 hours later in more than half the participants, and in some cases up to day 30 of monitored abstinence. The concentration detected doesn't reliably correlate with being impaired at the time of the checkpoint — precisely the scientific reason why there's no numeric threshold like there is for alcohol.
- "There's no legal THC limit, so they can't penalize me": false. The absence of a numeric threshold doesn't mean absence of penalty — mere presence of the substance in the body is enough for the traffic administrative infraction (Art. 77.c), and proven actual influence is enough for the criminal offense (Art. 379.2 Criminal Code).
Frequently asked questions
A regular vehicle doesn't have the home protection of Article 18.2 of the Constitution. A camper van actually used as a residence can have it, according to the test set by the Supreme Court (real habitability + effective use), which in principle requires a judicial warrant or consent for a search — except for legal exceptions such as the owner's consent or situations of flagrant crime.
Instruction 7/2025 speaks of a private vehicle "parked" in general, without expressly distinguishing the type of parking location. Case law on camper vans as homes also doesn't distinguish by location, only by habitability and actual use. No case law has been found addressing both points combined.
On the administrative traffic route (Art. 77.c), mere presence of the substance in the body is enough, and impairment doesn't need to be proven — so an analytical positive can result in an administrative penalty even without actual impairment. On the criminal route (Art. 379.2 Criminal Code), case law requires proving actual influence on driving, not just analytical detection.
There's no guarantee that it is. It's an internal administrative instruction, actively questioned by authoritative voices (a magistrate of the Supreme Court's Criminal Chamber, among others), and there's still no substantive Supreme Court ruling on Article 36.16 as applied to vehicles that sets consolidated, definitive doctrine.
