Several laws answer different questions
Spain regulates cannabis through overlapping legal systems. Criminal law addresses prohibited production, trafficking and facilitation; public-security law covers specified conduct in public places; association law governs how organisations operate; pharmaceutical law governs medicines. These distinctions explain why private consumption, a registered club and a prescription cannot be treated as equivalent permissions. The applicable rule depends on the conduct, setting and purpose.
Criminal liability concerns more than a sale
Article 368 of the Criminal Code covers cultivation, manufacture and trafficking, together with acts promoting, favouring or facilitating illegal consumption, and possession for those purposes. Payment is therefore not the only relevant feature of a case. Personal consumption is not itself a criminal offence, but the purpose of possession and conduct involving other people can change the legal assessment. A private address or a nonprofit structure does not independently settle those questions.
Public possession has a separate administrative rule
Article 36.16 of Organic Law 4/2015 classifies unlawful consumption or possession in public places, public establishments and collective transport as a serious administrative offence, even without an intention to traffic. Article 39 places serious offences within a statutory fine range of €601 to €30,000; the range is not a prediction of the outcome of every case. Article 36.18 separately concerns illicit planting or cultivation visible to the public where the conduct is not criminal. Location and visibility therefore matter independently of commercial activity.
Registration governs the organisation
Organic Law 1/2002 provides the framework for association statutes, decision-making, accounts and members' rights. Registration is about the legal organisation; it is not a cannabis retail licence. In judgment 100/2018, the Constitutional Court annulled Catalonia's cannabis-association law because of the division of legislative powers. The judgment distinguishes associations concerned with information, study or debate from a regional framework organising supply and consumption. Local premises rules and regional association administration operate within those wider national limits.
Medicinal preparations follow a pharmaceutical route
Royal Decree 903/2025 established conditions for standardised cannabis preparations used in specified pharmacy-compounded formulas. The framework involves specialist prescribing, hospital pharmacy preparation and dispensing, product requirements and patient follow-up. A national formulary monograph was published in 2026. This system sits alongside authorised medicines and is institutionally separate from social-club membership. Its controls concern pharmaceutical quality, clinical responsibility and traceability.
Why the distinctions have practical consequences
The same broad word, cannabis, can refer to very different legal situations: a medicine handled through healthcare, public possession, or the activities of an association. Each has its own decision-maker and evidence. A club's statutes explain membership rights; they do not replace criminal law. A medical document concerns treatment; it does not create a general public-consumption permission. Spain's framework is clearest when the specific activity and the relevant legal system are identified together.
