Weed is not fully legal in Spain, but it is not treated as a crime in every setting either. Using cannabis inside your own home is decriminalized, while carrying or consuming it in any public space is an administrative offense with fines starting at €601. There is no legal recreational market. Private cannabis social clubs operate in a grey area for residents, and a 2025 royal decree created the country’s first formal pathway for hospital-dispensed medical cannabis.
Private Use at Home
Spanish law does not punish you for consuming cannabis inside your own home. The protection comes from constitutional privacy principles rather than any statute explicitly legalizing the drug. The word that matters is “private” — your residence, not a friend’s balcony visible from the street, not a hotel corridor, not a park bench.
Home cultivation follows the same logic. Growing cannabis for personal use is tolerated as long as the plants are not visible from public areas and the quantity is clearly for your own consumption. Plants that can be seen from the street or a neighbor’s property are treated as a serious administrative infraction under Ley Orgánica 4/2015, carrying fines from €601 to €30,000.1Agencia Estatal Boletín Oficial del Estado. Ley Orgánica 4/2015, de 30 de Marzo, de Protección de la Seguridad Ciudadana
No statute sets a specific plant count. Courts have generally accepted that cultivation solely for self-consumption is not a criminal offense, and the practical risk point is quantity. The Spanish National Toxicology Institute set personal-use thresholds at roughly 100 grams for herbal cannabis (a five-day supply benchmark) and 25 grams for resin.2The European Union Drugs Agency (EUDA). Threshold Quantities for Drug Offences – Section: Threshold Quantities for Personal Possession Offences Above those amounts, you risk a trafficking investigation, which moves things from administrative territory into criminal law.
Seeds are legal to buy and sell. Seed shops operate openly in most cities because seeds contain no THC and are not a controlled substance. The legal risk begins at germination.
Public Possession and Consumption
Anything cannabis-related in public is an administrative offense. Smoking a joint on the street, carrying it in your pocket while walking, consuming in a park, on public transit, or outside a bar — all fall under Ley Orgánica 4/2015 and are classified as serious infractions.1Agencia Estatal Boletín Oficial del Estado. Ley Orgánica 4/2015, de 30 de Marzo, de Protección de la Seguridad Ciudadana
Fines run from €601 to €30,000 depending on circumstances and quantity. The important point is that these are administrative penalties, not criminal ones. Paying does not create a criminal record because the offense is an infraction rather than a crime.3The European Union Drugs Agency (EUDA). Penalties for Drug Law Offences at a Glance The fine itself can still be substantial, and police will confiscate any cannabis they find.
You can also apply to suspend the fine by voluntarily entering a drug treatment or rehabilitation program. A first-time offense with a small amount doesn’t have to end in a permanent financial penalty, but you have to complete the program or the fine is reinstated.
Cannabis Social Clubs
Cannabis social clubs are private, nonprofit associations where members collectively grow and share cannabis. They rest on two legal principles: private consumption is not punished, and shared consumption among a closed group of adults is not considered trafficking under Spanish case law. The system isn’t explicitly legal, but it has been broadly tolerated, especially in Barcelona and the rest of Catalonia.
Clubs must register as nonprofit associations. They are expected to produce only enough cannabis to meet their members’ needs and cannot advertise publicly. Membership requires an invitation from an existing member, and clubs verify identity with government-issued photo ID. Sales to non-members are illegal. The model is collective cultivation, not retail.
Legal status varies by region. Catalonia’s parliament passed formal regulations for cannabis clubs in 2017, but Spain’s Constitutional Court struck those rules down. Barcelona then published nonbinding guidelines covering proximity to schools, operating hours, and maximum membership sizes, which clubs there generally follow. Outside Catalonia, clubs exist in cities like Madrid, Valencia, and Málaga without even that informal framework.
Each club essentially operates at its own legal risk. Courts have tolerated clubs that stay small, serve only members, and avoid anything that looks commercial. Clubs that grow too large, admit walk-ins, or sell on-site to strangers have faced criminal prosecution for drug trafficking. Where the line sits between tolerated association and illegal distribution is drawn by individual judges, not by any clear statute.
When Cannabis Becomes a Criminal Matter
Criminal law applies once cannabis activity moves past personal use. Article 368 of the Penal Code covers anyone who cultivates, processes, or traffics drugs, or who otherwise facilitates illegal consumption. Spanish law distinguishes between substances that cause serious health damage (like cocaine and heroin) and those that don’t. Cannabis sits in the less-severe category, carrying one to three years in prison plus a fine of one to two times the value of the seized drugs.4Ministry of Justice (Spain). Criminal Code 2016
Article 369 adds aggravating factors that push penalties higher:
- Large quantities. The aggravated threshold is 10 kilograms for herbal cannabis (roughly 500 days’ supply) and 2.5 kilograms for resin.5The European Union Drugs Agency (EUDA). Threshold Quantities for Drug Offences
- Sales involving anyone under 18.
- Operating as part of a criminal organization.
- Abuse of a professional or public position to facilitate trafficking.
Aggravated cannabis trafficking carries roughly 1.5 to 4.5 years in prison. All drugs, equipment, vehicles, and financial proceeds connected to the offense can be confiscated.
Driving After Using Cannabis
Spain runs a zero-tolerance drug driving policy. Since 2014, a positive roadside saliva test for any controlled substance, THC included, triggers a €1,000 fine and a six-point deduction from your license, regardless of whether the substance actually impaired your driving. There is no minimum concentration threshold. Any detectable presence counts.
You can dispute a positive saliva test by requesting a confirmatory blood test at a health center. The traffic authority covers the cost if the blood test is negative. If it confirms drugs, you pay for the test and still face the fine and point deduction.6ETSC (European Transport Safety Council). Drug Detection Procedures in Spain
Refusing the test is worse than failing it. Under Article 383 of the Penal Code, refusing a roadside drug test is a criminal offense punishable by six months to one year in prison and a driving ban of one to four years.6ETSC (European Transport Safety Council). Drug Detection Procedures in Spain A refusal conviction goes on your criminal record. In many countries refusing a test is the lesser penalty, but in Spain it works the other way around.
Medical Cannabis
Spain’s medical cannabis framework changed in 2025. For years, the country had no formal pathway for cannabis-based treatments. A 2022 congressional subcommittee asked the Spanish Agency of Medicines and Medical Devices (AEMPS) to develop regulations after recognizing the therapeutic potential of cannabis.7Science Media Centre Spain. What Do We Know About Use Medical Cannabis? Questions and Answers About Its Regulation in Spain
Royal Decree 903/2025 created Spain’s first regulated pathway. The decree restricts the entire supply chain to hospitals. Only specialist physicians working in hospitals can prescribe cannabis preparations, and only hospital pharmacy services can compound and dispense them. Community pharmacies are shut out of the process.
Under the decree, standardized cannabis preparations may be supplied only to hospital pharmacy services or exported. Hospital pharmacists prepare individualized formulations from those preparations based on a doctor’s prescription and dispense them to inpatients and outpatients. AEMPS is responsible for creating the monographs that will define which conditions qualify, but those details are still being developed.
Before the decree, the only legal options were pharmaceutical products like Sativex (for multiple sclerosis spasticity) and Epidiolex (for certain forms of epilepsy), both available only through hospital prescriptions for narrow indications. Broad patient access to whole-plant cannabis or general-purpose cannabis prescriptions is still not available through conventional medical channels.
CBD Products
CBD sits in its own regulatory space, separate from THC-containing cannabis. Products derived from industrial hemp are generally legal for sale as long as THC content stays below 0.3%, a threshold the EU raised from 0.2% effective January 2023.
The bigger restriction is what you can do with CBD. Spain permits it mainly for external use, meaning cosmetics, topical creams, and massage oils. Ingestible CBD products like oils, capsules, and edibles are much more restricted. The European Commission classifies CBD as a “novel food,” so it cannot be legally marketed as a food supplement without specific authorization under EU novel food regulations.8European Food Safety Authority. Provisional Safe Level for Cannabidiol as a Novel Food Until those authorizations are granted, ingestible CBD stays in regulatory limbo across the EU, Spain included.
You will see CBD flower in Spanish shops labeled for “aromatic” or “collectible” purposes. Smoking or vaping it is the obvious intended use, but marketing it that way creates regulatory problems. Enforcement against CBD shops has been inconsistent, and these products are widely available despite the ambiguous status.
Rules That Catch Tourists Off Guard
Tourists are subject to the same cannabis laws as residents and face a few additional complications. Private-use decriminalization only protects consumption in your own home, and a hotel room is not legally equivalent to a private residence in every interpretation. Smoking in a rental apartment where it’s visible or detectable from shared spaces can also cause problems.
Cannabis social clubs in Barcelona and other cities sometimes accept foreign visitors, but policies vary. Most require government-issued photo ID such as a passport, driver’s license, or Spanish residency card. Some restrict membership to Spanish residents or require a local address, so checking in advance is essential. Whatever a club allows, any cannabis you obtain inside becomes illegal the moment you carry it onto the street.
Tourists caught in public face the same €601 to €30,000 fines that apply to anyone else.1Agencia Estatal Boletín Oficial del Estado. Ley Orgánica 4/2015, de 30 de Marzo, de Protección de la Seguridad Ciudadana Because these are administrative, they won’t produce a criminal record, but they can be expensive and the cannabis will be confiscated. Attempting to leave Spain carrying any amount is a different matter entirely: international trafficking, with criminal consequences far more serious than a street-level fine.
Cannabis and Your Job
Spanish labor law does not give every employer blanket authority to drug-test workers. Random testing is generally not permitted without the employee’s consent or a specific justification. Employers in safety-sensitive industries like transportation, construction, and heavy machinery have broader grounds to require testing when impairment poses a genuine risk to others.
If an employee cannot perform their duties due to cannabis consumption, the employer can take disciplinary action under standard employment law. The typical process requires at least one formal warning before termination, except in safety-critical roles where immediate dismissal may be justified. The fact that private cannabis use is decriminalized does not protect you at work. Your employer is not bound by the public-versus-private distinction that shields you from administrative fines at home.
