Criminal Lawyers for Drug Houses (Narcopisos) Defense

Drug houses (narcopisos) are dwellings used as retail drug distribution points. Common in certain urban neighborhoods, these apartments attract drug buyers and create significant community disturbance. Police operations against drug houses typically involve coordinated raids with search warrants.

What Are Drug Houses

A drug house is a dwelling used as a point of sale for drugs. The conduct remains a trafficking offence under Art. 368 CP, but it presents a procedural particularity of the first order: to access the evidence, the police must enter a home, which activates reinforced constitutional guarantees. Another particularity is the plurality of people usually present —owner, occupants, consumers, visitors—, which requires carefully delimiting the liability of each one. The mere fact of being in the property does not automatically make a person responsible for the point of sale; the prosecution must prove the specific participation of each individual.

Search Legality

The inviolability of the home (Art. 18.2 Spanish Constitution) can only be limited by reasoned judicial authorization, the occupant's consent, or flagrant crime. In drug house cases, the legality of the entry and search is, almost always, the most vulnerable point of the prosecution's case, because all the incriminating evidence (the drugs, the tools, the cash) derives from that entry. Our defense therefore meticulously examines every aspect of the search warrant and its execution: insufficient motivation, a flagrancy that was not strict, vitiated consent, the absence of the Court Clerk where required, or a disproportionate scope.

Defense Strategies

On that basis, the defense focuses on: challenging the search warrant's legal basis —where the violation of the fundamental right is established, the radical nullity of the diligence operates and, by connection of unlawfulness (Art. 11.1 LOPJ), that of all derived evidence—; proving the client had no knowledge or control over the drugs found (shared apartments, visitors, subletting); disputing drug quantities and purity through independent laboratory analysis; and arguing that the evidence was improperly handled during seizure, breaking the chain of custody. The aim is to clearly separate the organizer of the point of sale from those who merely happened to be in the property.

Procedural stages and the competent court: from the investigating judge to the National Court

A suspected narcopiso case opens with the investigation phase, directed by the Investigating Court (Juzgado de Instrucción) of the judicial district where the property is located. This phase produces the core evidence: entry and search of the premises, laboratory analysis of the seized substance, statements from suspects and witnesses and, where applicable, the interception of communications. The defence is present from the outset to scrutinise each act, propose exculpatory measures and challenge the suspect's personal situation so that pre-trial detention does not operate as an advance on the sentence.

Once the investigation closes, the trial falls to the Criminal Court (Juzgado de lo Penal) where the penalty sought does not exceed five years, and to the Provincial Court (Audiencia Provincial) where it does, which is common in the aggravated subtypes of Article 369. This split determines the composition of the bench and the later appeal regime.

One competence rule must not be overlooked: where drug trafficking is committed by gangs or organisations and has effects in the territory of more than one Provincial Court, or has an international dimension, jurisdiction lies with the National Court (Audiencia Nacional) under Article 65.1.d of the Organic Law of the Judiciary. Correctly identifying the competent court at the outset is essential, because a mistaken position on jurisdiction shapes the entire strategy and can generate nullities.

Expert evidence on the substance and the lawfulness of searches and wiretaps

In trafficking cases the forensic evidence is decisive. The official laboratory report establishes the nature of the substance, its net weight once cutting agents are deducted and, above all, its degree of purity, a figure that conditions the legal classification, including any finding of notoria importancia under the thresholds set by Supreme Court case-law. The defence examines the chain of custody from seizure to analysis, because any unjustified break in the traceability of the sample can strip the result of evidential force.

A second line of scrutiny is the lawfulness of interference with fundamental rights. Entry into and search of the property require a reasoned judicial order or, failing that, the valid consent of the occupant or a situation of flagrancy, respecting the inviolability of the home under Article 18.2 of the Constitution. Telephone and electronic interceptions are governed by Articles 588 bis a and following of the Criminal Procedure Act, which demand judicial authorisation grounded in objective indicia and the principles of specialty, suitability, exceptionality and proportionality.

Where any of these measures is obtained in breach of fundamental rights, the evidence is void and drags down the evidence derived from it. For that reason, technical analysis of the authorising orders, of their reasoning and of their periodic judicial oversight is central to the defence in these proceedings.

The boundary between personal use and trafficking, the minor-significance mitigation and addiction-based circumstances

Not every possession of drugs is a crime. Article 368 punishes conduct aimed at promoting or facilitating the unlawful consumption of others, so possession for personal use, individual or shared among consumers under defined conditions, falls outside the offence. The dividing line is built from indicia such as the quantity seized relative to the consumption pattern, the way the substance is presented, the presence of weighing or distribution tools and the proven destination; rebutting that inference of pre-ordination to trafficking is one of the recurring axes of the defence.

For less serious cases, Article 368.2 allows the court to impose the penalty one degree lower, having regard to the minor significance of the act and the personal circumstances of the offender; that finding also opens up possibilities regarding prescription, suspension and substitution of the sentence.

Where the conduct is linked to a serious addiction, the Code offers graduated responses. The full defence under Article 20.2 applies where, through full intoxication or withdrawal syndrome, the capacity to understand or to act on that understanding is nullified; where the impairment is significant but not total, it operates as an incomplete defence under Article 21.1, and in milder cases as a mitigating circumstance under Article 21.2. These circumstances can be combined with rehabilitation and steer the sentence towards treatment.

Limitation of the offence and plea agreement: time-frames and routes to early resolution

Limitation is calculated under Article 131 of the Criminal Code from the maximum penalty laid down for each modality. The basic offence under Article 368 concerning substances that cause serious harm to health, punishable by three to six years' imprisonment, becomes time-barred after ten years. The modality concerning substances that do not cause serious harm, punishable by one to three years, becomes time-barred after five years. It should be made clear that there is no intermediate three-year bracket in the current wording of Article 131.

In the aggravated subtypes of Articles 369 and 370, which provide for the penalty raised by one or two degrees above the basic offence, the maximum penalty can reach brackets that place limitation at ten or even fifteen years, depending on the specific aggravation found and the resulting penalty. The period is interrupted when the proceedings are effectively directed against the suspect, in the terms of Article 132 itself.

Faced with strong evidence, a plea agreement (conformidad) allows the outcome of the proceedings to be brought forward by negotiating the classification and the penalty with the prosecution, with legally provided sentencing benefits. Its appropriateness must be assessed case by case, weighing the strength of the evidence, the possible nullity of key measures and the presence of mitigations such as that of Article 368.2 or those arising from addiction.
