Every September and February, thousands of exchange students land in Valencia, and plenty of them arrive with the wrong idea about cannabis in Spain. Some assume it works like Amsterdam. Others figure that because it is legal back home, they are covered here too. Neither is true.
Spanish law draws a line between what is a crime, what is an administrative offence and what is left to private life. That line is worth understanding before the first welcome party, because a fine for smoking in the street starts at €601, which is a big chunk of a monthly Erasmus grant.
This guide sets out what the law says, what the courts have ruled and where things remain genuinely unclear, with links to the sources so you can check them yourself.
Valencia: one of Europe’s Erasmus capitals
Valencia has been one of the most sought-after exchange destinations in Europe for years. According to the University of Valencia’s own report for the 2019-2020 academic year, it welcomed 2,305 incoming Erasmus students that year and describes itself as a European benchmark for the programme by total participants since its creation (University of Valencia annual report, 2019-2020).
Add the students at the Polytechnic University of Valencia, which also regularly ranks among the European universities hosting the most exchange students. Drawing on European Commission data, the press reported in 2021 that the University of Valencia had become the top host university in Europe, with 2,401 international students.
That means several thousand young people a year, mostly aged 19 to 25, living in a city where cannabis law is exactly the same as in the rest of Spain. The Valencia region has no cannabis rules of its own.
Cannabis is not legal in Spain, but not everything is a crime
The starting point is simple: Spain has no legal recreational cannabis market. There are no licensed stores selling THC flower and no regulated retail system like the ones in many US states.
Personal use itself, however, is not a criminal offence. The system works on two levels. The Criminal Code punishes trafficking and anything that facilitates drug use by other people. The public safety law penalises use and possession in public places through administrative fines. What happens inside a private home, with no third parties involved, falls outside both.
Using or carrying cannabis in public: fines from €601
Article 36.16 of Organic Law 4/2015 on the protection of public safety, often called the “gag law” in Spanish media, classes the use or possession of illegal drugs in public places, streets, public venues or public transport as a serious offence, even when the drugs are not meant for sale. Leaving paraphernalia lying around in those places is also covered.
Article 39.1 sets fines for serious offences at €601 to €30,000. The lowest band, which is what usually applies to a joint or a small amount, runs from €601 to €10,400. Under Article 54.3, paying within fifteen days of being notified gets you a 50% discount, in exchange for giving up the right to appeal.
That applies on Malvarrosa beach, in the Turia gardens, at a metro stop or in a car parked on the street. Article 36.18 also penalises growing plants that are visible from a public space, so a plant on the balcony is not a good idea either.
One detail applies only to minors: the law’s fifth additional provision allows the fine to be suspended if the minor agrees to treatment or education programmes. There is no equivalent route for adults under the national law.
When criminal law kicks in: Article 368
Article 368 of the Spanish Criminal Code punishes anyone who grows, produces or traffics drugs, or who in any other way promotes, encourages or facilitates their illegal use. For substances that do not cause serious harm to health, the category courts apply to cannabis, the penalty is one to three years in prison plus a fine.
Money does not have to change hands. Passing cannabis to someone else, even a flatmate and for free, can count as “facilitating”. Quantity, packaging and carrying small bills are all things police and judges look at when deciding whether something is personal use or dealing.
The article allows a lighter sentence for minor cases, but a conviction still means a criminal record, which can cause problems later with visas, internships or jobs.
Private use and how members-only associations work
The space the law leaves open is the private sphere. That gap is where Spain’s cannabis consumer associations grew up: non-profit organisations, registered as associations, where adults who already use cannabis share an enclosed space to do so away from the street.
They are not coffeeshops and they are not open to the public. Most follow a similar set of rules: members must be adults (some set the bar at 21), new members join by invitation or endorsement from an existing member, there is a membership fee, and consumption happens on the premises. Some also have a waiting period between applying and being admitted. If you want to understand how they are organised locally, Weedestiny has a guide to cannabis clubs in Valencia and their admission rules.
To be clear: an association being listed in a government register does not make everything that happens inside legal. Registration approves the association’s bylaws, not its activity with cannabis.
The 2015 Supreme Court ruling and why this is still a grey area
The key legal reference is Supreme Court judgment 484/2015 of 7 September, handed down by the full criminal chamber. The case involved a Bilbao association with 290 members that was open to new sign-ups. The court held that organised cultivation and distribution to a large group of that kind meets the definition of the Article 368 offence.
The same judgment accepted that small-scale shared cultivation may fall outside criminal law if certain markers are present: a small group of identified regular users, consumption in an enclosed space, and quantities limited to immediate use. That is the narrow margin associations operate in.
On top of that, the Constitutional Court struck down Navarre’s law regulating these groups in 2017 (STC 144/2017) and Catalonia’s in 2018, finding that regulating cannabis supply encroaches on the State’s exclusive power over criminal law. Valencia has no law of its own. Unlike a US state, a Spanish region cannot simply vote to legalise. So the model remains a grey area: tolerated in practice in many cases, but without an explicit legal framework behind it.
Legal at home does not mean legal here
Several European countries have changed their laws in recent years: Malta in 2021, Luxembourg in 2023 and Germany in 2024, as summarised by the European Union Drugs Agency (EUDA). Those rules apply only within each country. In Valencia, Spanish law applies, whatever your passport says.
Do not travel with cannabis between countries either, even inside the Schengen area where there are usually no fixed border checks. Carrying it on a plane, coach or international train can be treated as drug trafficking or smuggling rather than a simple fine. Prescribed cannabinoid medicines follow their own rules and need paperwork, so check before you travel.
Edibles: the high that arrives late
THC edibles carry a particular risk for less experienced users. Taken by mouth, cannabis can take anywhere from half an hour to two hours to kick in, and it is common for people to take a second dose thinking the first one did nothing.
A study in Annals of Internal Medicine in 2019 (Monte et al.) reviewed 9,973 emergency department visits at a large Colorado hospital. Edibles accounted for 10.7% of cannabis-attributable visits between 2014 and 2016, despite making up only 0.32% of the state’s THC sales. They were also linked to more acute psychiatric and cardiovascular symptoms than inhaled cannabis.
Alcohol and cannabis: a combination that adds up
Erasmus life involves a lot of partying, and mixing alcohol with cannabis is common. A controlled trial published in Clinical Chemistry in 2015 (Hartman et al.), involving 32 adult cannabis users, found that a low dose of alcohol significantly raised peak blood THC levels: at the higher cannabis dose, the peak rose from 42.2 to 67.5 µg/L.
The authors suggest this may help explain why the combination impairs performance more than either substance alone. In practice it means more dizziness, nausea, anxiety and slower reactions. And if a vehicle is involved, driving with drugs in your system carries a €1,000 fine and the loss of six licence points in Spain, on top of the obvious dangers.
Student life raises its own questions about cannabis, and the evidence is more mixed than the folklore. Read what studies say about cannabis and creativity, whether marijuana really helps you sleep better, and why edibles such as marijuana butter hit harder and later than smoking.
What to keep in mind before you arrive
If you are spending a semester or a year in Valencia, the practical points are few. Using or carrying cannabis in public is fined from €601. Sharing or selling it can be a crime. Private homes and adult members-only associations are the space the courts tolerate, with caveats and no absolute guarantees.
No law from your home country protects you here, and crossing borders with cannabis is a bad idea in any circumstances. If you do choose to use, do it informed, do not mix it with alcohol, be especially careful with edibles and never drive. And if you have doubts about a specific situation, a lawyer or your university’s student support service is a far better source than any online forum.
