In April 2016 the Basque Country passed an addictions law that, for the first time in Basque legislation, expressly mentioned associations of cannabis users. The Spanish government took it to the Constitutional Court. Almost two years later the court did not strike the provision down, but it read it so narrowly that very little of it was left.
The story makes more sense alongside two others: Navarre, which tried first and lost its entire law, and two criminal cases involving Bilbao associations that ended up shaping Supreme Court doctrine for the whole of Spain.
This piece looks at what each law actually said, what the courts decided and what it all means today for an adult who wants to join an association in Bilbao. Every ruling cited is linked to its official source.
Navarre went first with Regional Law 24/2014
The first regional attempt was Navarre’s Ley Foral 24/2014 of 2 December, which regulated cannabis user collectives in the region. Its aim was to give a legal framework to the associations already operating there.
The Spanish prime minister challenged the whole law (case 1534-2015). In judgment STC 144/2017 of 14 December, the full Constitutional Court declared it unconstitutional and void in its entirety. The court found that the law regulated “the consumption, supply and dispensing of cannabis” and gave the collectives functions of stockpiling and distribution. That touches on offences defined in the Criminal Code, which under Article 149.1.6 of the Spanish Constitution is the exclusive domain of the national government.
The court added that a region’s power over associations covers how they are set up and run, but cannot stretch to regulating what the association does when that activity borders on the criminal.
What Article 83 of the Basque law actually says
The Basque statute is Law 1/2016 of 7 April on Comprehensive Care for Addictions and Drug Dependence, published in the Basque Official Gazette (BOPV) No. 69 on 13 April 2016. It is a broad public health law covering alcohol, tobacco and other drugs, and cannabis takes up very little of it.
Article 83, headed “Entities of cannabis users”, states that, in order to protect health and reduce harm, legally registered non-profit entities made up of adult cannabis users will be regulated by a future decree. Their aims must include cooperating with the authorities, preventing addiction and promoting responsible use.
The second paragraph says that only adults may enter their premises, and leaves it to the future decree to set membership rules, the information members must receive and the health authorities’ inspection powers. Article 6.3 of the same law adds that adult users who belong to these entities must not be discriminated against on that basis.
The government’s challenge and judgment STC 29/2018
This time the government challenged only Article 83 (case 231-2017), on grounds similar to the Navarre case: criminal law, public security and health. The Constitutional Court ruled in STC 29/2018 of 8 March.
The court dismissed the challenge and held that the article is not unconstitutional, but only “provided it is interpreted” in a specific way: without determining what type of association these entities are, the provision merely requires them to carry out certain cooperation duties with the health authorities.
Lawyers call this a conforming interpretation. The court stressed that nothing in the article says members can obtain cannabis through the entity, or that they can consume it on the premises. Read that way, the article stands. Read as a framework for cultivation-and-consumption clubs, it would not.
Why the Basque provision survived and Navarre’s law did not
The difference lies in what each text said. Navarre’s law went to the heart of the matter: how collectives source cannabis, how it is handed out, under what conditions it is consumed. The Basque article was a single referral to a future decree plus a duty to cooperate with public health services.
The same reasoning was later applied to Catalonia. Its Law 13/2017 of 6 July on cannabis user associations, which did set out a full regime for shared cultivation and consumption, was struck down in STC 100/2018 of 19 September. Three rulings in nine months sent a clear message: Spain’s regions cannot regulate the supply of cannabis, because doing so affects how crimes are defined, and that belongs to the national government alone.
That is the key contrast with the United States. In the US, states have built licensed cannabis markets under their own laws despite federal prohibition. In Spain, a region simply has no power to do the equivalent.
The decree that never came
Article 83 relied on a decree to spell out how these entities would work. As of this writing, we have not found any decree in the Basque Official Gazette implementing it, and STC 29/2018 left little room for one: any regulation that tried to govern cultivation or distribution would run straight into the court’s doctrine.
Some city councils have acted through zoning instead. San Sebastián passed a bylaw setting where club premises can be located, for example away from schools, and the Basque High Court upheld it in 2016, noting that it only regulates location and premises, not anything to do with cannabis itself. That same year Bilbao’s city council agreed to draft similar zoning rules while the regional decree was pending.
Bilbao at the centre: the Ebers and Pannagh cases
Two of the rulings that set the Supreme Court’s doctrine on cannabis associations came out of Bilbao. The first, STS 484/2015 of 7 September, issued by the full criminal chamber, concerned the Ebers association, which had 290 members. The Bizkaia Provincial Court had acquitted its organisers; the Supreme Court convicted them, sentencing three to eight months in prison and a €5,000 fine, on the basis of an avoidable mistake of law.
The Constitutional Court later set that conviction aside in STC 146/2017, not on the merits but because the Supreme Court had assessed whether the defendants knew their conduct was unlawful without hearing them. In the same judgment it rejected the claim that the conviction breached the principle of legality. When the Supreme Court reheard the case in 2018, it acquitted the defendants because, without having seen the evidence first-hand, it could not rule out that their mistake had been unavoidable.
The Pannagh case followed a similar path: a Supreme Court conviction in STS 788/2015 of 9 December, then annulment by the Constitutional Court in STC 37/2018 of 23 April for the same breach of the right to a defence. How these cases ended did not change the doctrine: organising cultivation and distribution for a large, open group is a crime.
The rules that apply today: Criminal Code and public safety law
Bilbao is under the same legal framework as the rest of Spain. Article 368 of the Criminal Code punishes promoting, encouraging or facilitating drug use by others, with one to three years in prison where cannabis is concerned.
Organic Law 4/2015 treats use and possession in public as a serious offence, with fines of €601 to €30,000 (€601 to €10,400 in the lowest band), halved if paid within fifteen days. Article 83 of the Basque law changes none of this.
What this means if you want to join in Bilbao
In practice, Bilbao’s associations operate as private non-profit entities listed in the register of associations, and they lean on the Supreme Court’s criteria: a group of identified members, consumption in an enclosed space and quantities tied to personal use. To join, you will usually need to be 18 or over, come in through an invitation or endorsement from an existing member, pay a membership fee and consume on the premises, never taking cannabis out onto the street. To see how they are organised, Weedestiny has information on cannabis clubs and associations in Bilbao and their entry requirements.
Two things are worth keeping in mind. Being listed in the register of associations validates the bylaws, not the activity involving cannabis. And using cannabis outside the premises, in the street or a park, is fined exactly as it would be in any other Spanish city, whichever association you belong to.
The Basque episode is one chapter of a wider story about how Europe regulates the cannabis economy. The same tension shows up in retail, where opening a CBD store means working through grey areas; in cosmetics, where CBD in beauty products follows its own rules; and in advertising, where cannabis digital marketing is shaped by platform bans.
What remains unresolved
The Basque law acknowledged that these entities exist, gave them a public health purpose and barred minors from their premises. What it could not do was regulate the core issue: where the cannabis their members use comes from. That depends on the Criminal Code and on how the courts read it, not on the Basque Parliament.
Until there is reform at national level, the model stays in a grey area: half-recognised by a regional law, tolerated within certain limits by case law and offering no absolute guarantees to anyone. For members, the sensible advice has not changed: use responsibly, only in private, and with reliable information about what the law does and does not allow.
