Criminal Lawyers for Heroin Trafficking Defense
Specialized defense in heroin trafficking cases. Substance causing serious harm to health with enhanced penalties.
Last updated:
Heroin trafficking carries some of the most severe penalties in Spanish drug crime law because heroin is classified as a substance that causes serious harm to health (Art. 368 CP). The base penalty is 3 to 6 years imprisonment, significantly higher than for cannabis or hashish.
Legal Framework
Heroin —and, with it, the other opiates, including fentanyl— is classified as a substance that causes serious harm to health, which places it in the highest bracket of Art. 368 CP. The protected legal interest is public health, and the classification as "serious harm" not only raises the base penalty but also affects all the aggravating thresholds. As with the rest of drugs, what matters for those thresholds is not the gross weight but the pure content: street heroin is typically cut with additives, reducing its purity to around 15-30%, so an independent analysis of the pure content can decisively alter the legal classification.
Penalties
The base penalty is prison of 3 to 6 years and a fine proportional to the value of the drug. The notoria importancia (Art. 369 CP), which the Supreme Court sets for heroin at around 300 grams of pure substance, raises the penalty to the 6 to 9 years range. Membership of a criminal organization (Art. 369 bis CP) aggravates it further, potentially exceeding 13 years, and there are specific subtypes when the drug is distributed to minors or in educational or penitentiary centres. Because the thresholds are calculated on pure content, the purity analysis is often the single most consequential point of the case.
Defense Strategies
Our defense focuses on: demanding independent purity analysis (official lab results can be challenged); arguing drug addiction as a mitigating or exempting circumstance (Arts. 20.2, 21.1-2 CP) —heroin is the substance where this carries the greatest weight, since many of those accused are themselves addicts selling to fund their own consumption—; steering the case toward the suspension of the sentence conditioned on a detoxification programme (Art. 80.5 CP), available for sentences of up to five years; challenging the attribution of possession (especially in shared spaces or vehicles); and scrutinising surveillance and arrest procedures for constitutional violations, including the nullity of phone taps lacking objective grounds.

Drug Crimes in Spain: Defence Guide for Trafficking, Possession and Cannabis Clubs
Drug offences are among the most prosecuted crimes in Spain. Articles 368-378 of the Criminal Code distinguish between drugs that cause serious harm to health (cocaine, heroin, amphetamines) and those of lesser harm (cannabis, MDMA). This distinction is pivotal — it directly determines the minimum and maximum prison sentences applicable.
Penalty Table: Drug Offences
| Offence | Article | Substance type | Penalty |
|---|---|---|---|
| Basic drug trafficking | Art. 368 | Serious harm (cocaine) | 3 – 6 years |
| Basic drug trafficking | Art. 368 | Lesser harm (cannabis) | 1 – 3 years |
| Aggravated trafficking (Art. 369) | Art. 369 | Large amounts/minors | 4.5 – 9 / 1.5 – 4.5 years |
| Criminal organisation (Art. 369 bis) | Art. 369 bis | Organised crime | 9 – 12 years |
| International trafficking (Art. 370) | Art. 370 | Cross-border/large scale | Upper half of applicable range |
| Personal possession (own use) | Not criminal | Personal amounts | Administrative fine only |
Key Defence Strategies
Own-Use Defence (Art. 368 CP)
If the quantity found corresponds to personal consumption patterns and there are no aggravating signs (scales, bags, large amounts of cash), the defence argues the substance was for personal use — not a criminal offence.
Cannabis Social Club Defence
Legally constituted cannabis clubs do not constitute drug trafficking if: membership is adult-only, closed distribution, no profit, no promotion, and quantities correspond to established consumption levels.
Challenging the 'Large Amount' Threshold
The threshold for 'large amount' (notoria importancia) is fixed by case law, not statute. Precise weighing with deduction of adulterants can bring quantities below the threshold.
Breaking the Chain of Custody
Drug evidence is often challenged on chain of custody grounds. Procedural irregularities in seizure, sealing, transfer or analysis can invalidate the forensic evidence.
Criminal Organization: Proving Role
Being part of an organisation requires stable, hierarchical structure. Sporadic cooperation or a minor role (driver, lookout) does not automatically trigger Art. 369 bis penalties.
Controlled Delivery and Police Provocation
Evidence obtained through unlawful police provocation (agent provocateur) is inadmissible. Distinguish between undercover infiltration (lawful) and provocation of an offence that would not otherwise occur.
Specific Mitigating Factors in Drug Offences
Addiction (Art. 21.2 CP)
Proven drug dependence can operate as mitigating (simple), highly qualified mitigating, or even incomplete defence, significantly reducing the penalty. Requires psychological and medical expert reports demonstrating that the addiction affected the offender's ability to understand the unlawfulness of their conduct.
Active Collaboration (Art. 376 CP)
Provides a 1-2 degree penalty reduction for the informant who supplies effective evidence to identify other suspects or dismantle the organisation. The information must be NEW, VERIFIABLE, and USEFUL. Strategic assessment is crucial before cooperating.
Shared Consumption Doctrine
The Supreme Court has defined 5 cumulative requirements: habitual identified consumers, closed premises, moderate quantity for immediate use, simultaneous consumption, and absence of profit. Failure of any one requirement converts the conduct into trafficking.
'Notoria Importancia' Thresholds by Substance
| Substance | Threshold (Pure) | Gross equivalent (approx.) | Penalty impact |
|---|---|---|---|
| Cocaine | 750 g pure | ~3–5 kg gross | 6–9 years |
| Heroin | 300 g pure | ~1–2 kg gross | 6–9 years |
| Hashish | 2,500 g THC | ~10 kg material | 1.5–4.5 years |
| MDMA | 240 g pure | ~720 pills | 6–9 years |
| Amphetamine | 90 g pure | ~300 g gross | 6–9 years |
| Methamphetamine | 15 g pure | ~30 g gross | 6–9 years |
Key Supreme Court Rulings
The Supreme Court confirms that cannabis clubs are lawful if they are genuinely closed associations, membership is strictly adult, no promotion is carried out beyond the membership, and quantities do not exceed personal consumption patterns. Any failure of these conditions may constitute drug trafficking.
The 'large amount' threshold must be calculated on the pure substance after subtracting adulterants and impurities. Gross weight is not the correct measurement. The defence should always request an independent quantitative analysis.
If police provocation created the intent to commit the offence (the accused would not have acted without the provocation), evidence is excluded under Art. 11.1 LOPJ. Mere opportunity provided by an undercover officer does not amount to provocation.
