Cocaine Trafficking Penalties in Spain 2026: Complete Guide

Cocaine trafficking is one of the most severely punished public-health offences in the Spanish Criminal Code. Cocaine is classified as a substance causing serious harm to health (Art. 368.1 CP), which means prison penalties of 3 to 6 years in its basic type — double those for cannabis. As criminal defence lawyers, we analyse the penalties, the aggravating factors and the main lines of defence, starting with the question most people ask first: what happens when the police find cocaine on you.

1. You Have Been Reported for Carrying Cocaine: What It Means and What Happens Next

Having cocaine seized by the police does not necessarily mean criminal proceedings. If the substance was for your own use and you were carrying it in the street, in premises open to the public or on public transport, the usual outcome is an administrative report for the infringement in Art. 36.16 of Organic Law 4/2015 on the Protection of Public Safety. If the quantity, the way it was divided up or what is found alongside it point to sale, the officers draw up a police report (atestado) for an offence against public health (Art. 368 CP) and the matter goes to court.

Art. 36.16 treats as a serious infringement «the unlawful consumption or possession of toxic drugs, narcotics or psychotropic substances, even if not intended for trafficking, in places, roads, public establishments or public transport» (unofficial translation). Two consequences follow: possession for personal use inside your own home does not fall within that provision, and the administrative file does not need to prove that you intended to sell.

The two routes are not added together for the same facts. If the conduct may be a criminal offence, Art. 45 of Organic Law 4/2015 requires the authorities to refer the matter to the judge or the public prosecutor and to wait for the criminal proceedings to end; if they end without a conviction, the administrative file may continue, bound by the facts the judge has held to be proven.

What to do (and what not to do): do not explain to the officers what the drug was for before speaking to a lawyer, check the weight and the packaging recorded in the seizure report and, if you are arrested, ask for a lawyer. Our guide on what to do if you are arrested with drugs covers those rights in detail.

2. Fine for Carrying 1 Gram or Half a Gram of Cocaine

The law does not set a fine per gram. Carrying half a gram, one gram or two grams in a public place for your own consumption is the same serious infringement under Art. 36.16, and Art. 39.1 of Organic Law 4/2015 punishes serious infringements with a fine of €601 to €30,000. What moves the amount is the band in which the fine is imposed.

The repeat infringement that leads to the medium band has a precise meaning: having committed, in the previous two years, more than one infringement of the same nature, declared by a final administrative decision. A fine set above the minimum band without explaining which circumstance justifies it can be challenged.

The penalty may also include confiscation of the substance (Art. 39.2.b), and municipal by-laws may introduce gradations within the statutory scale (Art. 32.3): the exact figure is only known when you read the notice opening the proceedings (acuerdo de incoación). A serious infringement becomes time-barred after one year (Art. 38.1).

This fine does not create a criminal record: final penalties are entered in the Central Register of Public Safety Infringements (Art. 43), which is used only to assess repeat infringements in the administrative sphere.

3. How to Reduce or Appeal a Cocaine Fine

The way to pay less is voluntary payment under Art. 54 of Organic Law 4/2015. Once you have been notified of the notice opening the proceedings, you have fifteen days to choose between two paths:

• Pay within the deadline: the fine is reduced by 50 %, the proceedings end on the day of payment and you are deemed to waive your right to submit arguments (any you have already filed are treated as not submitted). After that, the only option is an appeal before the administrative courts (contencioso-administrativo). A fine of €601 becomes €300.50.
• Submit arguments and evidence: the file continues under the ordinary procedure and the reduction is lost. It is worth it when there is something to dispute: that the place was not public, that the substance was not analysed, that the fine exceeds the minimum band without an Art. 33.2 circumstance, or that the infringement was already time-barred.

Can the fine be swapped for treatment? Only if the offender is a minor: the fifth additional provision of Organic Law 4/2015 allows it to be suspended if the minor accepts treatment, rehabilitation or re-education activities, and it is enforced if they abandon them. The law provides no such route for adults. In criminal proceedings, by contrast, completing a rehabilitation programme can reduce or suspend the sentence, as explained in our analysis of the sentence for a first drug offence.

4. How Many Grams of Cocaine Make It a Criminal Offence?

No rule sets a number of grams. Art. 368 CP punishes anyone who possesses the drug «for those purposes» (unofficial translation), that is, to traffic in it or to promote, encourage or facilitate its consumption by others. Selling a single wrap can be an offence; holding more for your own consumption, in principle, is not. The intended use decides, and the quantity is only an indication.

The courts work with two numerical references, both from the National Institute of Toxicology (INT), set out in the table of minimum psychoactive doses published by the Spanish judiciary (revised on 1 August 2021):

• Minimum psychoactive dose: 50 mg of cocaine. Below that quantity, supplying the drug may be regarded as falling outside the offence because it is insignificant. The Criminal Division of the Supreme Court agreed in a plenary session on 3 February 2005 to «continue applying the criterion of the National Institute of Toxicology on minimum psychoactive doses until a legislative reform takes place or another criterion or alternative is adopted» (unofficial translation). The table does not state whether that figure refers to pure substance, so the purity analysis should be checked.
• Supply for three to five days of consumption: 7.5 grams. The same table calculates it from an estimated maximum daily consumption of 1,500 mg, without stating whether this is pure cocaine or gross weight. It is a guideline, not a legal limit: exceeding it is an indication of trafficking, not proof, and staying below it does not prevent a conviction if a sale is proven.

The other indications (division into doses, scales, cash in small denominations, messages, surveillance) and how they weigh against proof that the person is a habitual user are analysed in drug possession versus trafficking.

5. Quantity of Cocaine and Likely Consequence

Quantity alone does not decide the outcome: purity, the place and, above all, the intended use that is proven all carry weight.

6. Basic Type: Prison of 3 to 6 Years (Art. 368.1 CP)

Article 368 punishes anyone who cultivates, produces, traffics or possesses for distribution substances causing serious harm to health — and cocaine is the paradigmatic example. The penalty is prison of 3 to 6 years and a fine of one to three times the value of the drug.

Important: a sale need not be proven. Possession intended for trafficking is enough: if the quantity exceeds personal use (the guideline is 7.5 grams, the three-to-five-day supply in the National Institute of Toxicology table), or there are indications of sale (scales, individual bags, cash in small denominations), there are indications of intent to traffic, which the court weighs as a whole.

7. Penalty for 20 Grams of Cocaine: Basic or Mitigated Offence

Twenty grams of cocaine is a long way from the notable-quantity threshold (750 grams of pure substance), so, if it is proven that the drug was intended for trafficking, the range is that of the basic offence: prison of 3 to 6 years and a fine of one to three times the value of the drug. That value is the final price of the product or the profit obtained or obtainable (Art. 377 CP), not a fixed scale.

If the intent to traffic is not proven, there is no offence: a habitual user who proves the addiction, with no indications of sale, can argue that it was a personal supply even if it exceeds the three-to-five-day reference.

If there is trafficking, two reductions are still possible:

• Minor seriousness (Art. 368, second paragraph): the court may impose the penalty one degree lower, prison of 1 year and 6 months to 3 years, in view of the minor seriousness of the act and the offender's personal circumstances, unless Art. 369 bis or Art. 370 applies. The one-degree reduction also extends to the proportional fine (STS 227/2026 of 19 March). See our analysis of street dealing and the mitigated offence of Art. 368.2.
• Completed rehabilitation (Art. 376, second paragraph): if the person was drug-dependent when the acts took place and proves that they have successfully completed a rehabilitation programme, the court may reduce the penalty by one or two degrees, provided the quantity is neither notable nor of extreme gravity.

With a final sentence of two years or less, an ordinary suspension is possible; Art. 80.5 CP also allows sentences of up to five years to be suspended where the offence was committed because of drug dependence and its requirements are met.

8. Notable Quantity: 6-9 Years (Art. 369.1.5 CP)

The aggravating factor of notable quantity is triggered from 750 grams of PURE cocaine (not gross weight). This distinction is crucial for the defence:

• The police weigh the drug gross (with adulterants).
• 1 kg of cocaine cut to 30% contains only 300 grams of pure substance.
• If purity is low, the pure weight may not reach 750 g, and the aggravating factor disappears.
• Requesting the purity analysis is the first line of defence in these cases.

The figure comes from the non-jurisdictional plenary agreement of the Criminal Division of the Supreme Court of 19 October 2001, which set the aggravating factor «from five hundred doses referred to daily consumption» according to the INT report, calculated on the substance «reduced to purity» (except for hashish) (unofficial translation); its table assigns 750 grams to cocaine hydrochloride. The agreement uses the numbering in force at the time; today it is circumstance 5 of Art. 369.1 CP. Where the quantity far exceeds the notable-quantity threshold, Art. 370 allows the penalty to be raised by one or two degrees, without setting a figure.

9. Criminal Organisation: 9-12 Years (Art. 369 bis CP)

Where trafficking is carried out within a criminal organisation, Art. 369 bis CP does not raise the penalty by one degree: it sets its own range of 9 to 12 years in prison and a fine of one to four times the value of the drug. Leaders, managers or administrators of the organisation receive the next higher degree: 12 years and 1 day to 18 years. The extreme-gravity cases of Art. 370 CP (use of vessels or aircraft, international networks, or quantities far above the notable-quantity threshold) raise the Art. 368 penalty by one or two degrees, up to a ceiling of 13 years and 6 months.

In large-scale cases before the National High Court, dozens of defendants are often investigated as members of the same organisation. The defence of individualisation — separating the accused's conduct from the whole — is fundamental: being present is not participating, and a mere relationship with others does not prove a criminal agreement.

10. Personal Use vs. Trafficking: the Red Line

Possession for personal use is not a criminal offence in Spain. In a public place it is an administrative infringement punishable by a fine (Art. 36.16 LO 4/2015). Exceeding the 7.5-gram guideline in the INT table (section 4) is an indication of trafficking, not an automatic presumption.

The defence can rebut that indication by proving:

• Habitual use: hair analysis, addiction treatment records.
• No indications of sale: no scales, no bags, no cash in small denominations.
• A purchase for the longer term: showing that the quantity was for personal consumption over several days or weeks.

11. Defence Strategies in Cocaine Trafficking

As criminal defence lawyers with experience in large-scale drug trafficking cases, our main lines of defence are:

1. Purity analysis

The first battle. If the pure substance does not reach 750 grams, there is no notable quantity and the range returns to that of the basic offence.

2. Nullity of wiretaps

In many organised trafficking cases, intercepted communications are central evidence. If the court order authorising them lacks sufficient reasoning, their nullity can be sought: Art. 11.1 of the Organic Law on the Judiciary (LOPJ) deprives of effect evidence obtained «directly or indirectly» in breach of fundamental rights (the fruit of the poisonous tree doctrine), and the effect on derived evidence is decided case by case.

3. Chain of custody

From seizure in the street to the INT laboratory: is everything sealed? Do the weights match? Is every transfer recorded? A break may undermine the reliability of the physical evidence.

4. Individualisation in large-scale cases

We separate our client's conduct from the whole. Being in a vehicle with drugs does not, on its own, prove that the person knew what was being transported. The burden of proof lies with the prosecution.

12. Summary Table of Cocaine Penalties

Frequently Asked Questions

Can I be convicted for a single transaction?

Yes. A single documented sale is enough to convict for drug trafficking. The activity does not need to be habitual.

Does adulterated cocaine change the penalty?

Yes. If the substance is extremely cut and the amount of active ingredient is minimal, the defence can argue that it does not reach the minimum psychoactive dose (50 mg for cocaine, according to the INT) and that the conduct falls outside the offence as insignificant.

Does cooperating with the police reduce the penalty?

Yes. Art. 376 CP allows the penalty to be reduced by one or two degrees if the accused, having voluntarily abandoned the criminal activity, provides effective evidence to identify other offenders.
