382 plants and 1 acquittal: the right to grow your own cannabis is enshrined in Spain

The Provincial Court of Las Palmas de Gran Canaria has acquitted a man accused of drug trafficking after authorities discovered 382 cannabis plants at home.

This historic acquittal, reported by the Spanish magazine Cannabis Magazine, is considered one of the most important victories for personal cannabis cultivation in Spain to date.

The case: quantity alone is no longer enough to establish guilt

The defendant, known as G.Z., was initially sentenced to four years' imprisonment and a fine of 65,315 euros following a police raid which led to the seizure of plants and cultivation equipment. The prosecutors had based their case solely on the large quantity of cannabis and its potential market value, presuming an intention to distribute.

However, the defense, led by’lawyer Héctor Brotons, succeeded in demonstrating that plants were cultivated exclusively for the personal consumption, without any evidence to suggest distribution or commercial activity. The court accepted these arguments, citing the absence of incriminating evidence such as sales records, packaging material or evidence of trafficking.

According to the ruling, «the mere number of plants or their weight cannot automatically constitute sufficient evidence for a trafficking conviction».

On the contrary, the court took into account the consumer habits of the defendants and demanded stronger evidence of criminal intent.

Legal principles at the heart of the judgment

The court's decision was largely based on two pillars of Spanish criminal law: the presumption of innocence and the principle in dubio pro reo (in case of doubt, rule in favor of the accused). As stipulated in article 24.2 of the Spanish Constitution, the prosecution must prove guilt beyond all reasonable doubt. In this case, the absence of evidence other than the plants themselves meant that the burden of proof was not met.

The decision criticized judgment rendered by the lower court, which had based itself solely on the size of the plantation without taking into account other relevant factors, such as the regular consumer status and the absence of any evidence of trafficking. The acquittal not only absolves G.Z., but also creates a judicial precedent likely to have an impact on current and future business involving home cannabis cultivation.

Consequences for cannabis growers in Spain

This verdict sends a strong message to both cannabis growers and law enforcement agencies. For the former, it reinforces the argument that home cultivation for personal use, even on a large scale, should not automatically be equated with a drug trafficking. For the latter, it raises the level of proof required to justify criminal proceedings.

This case also highlights the tension between the evolution of social attitudes towards cannabis in Spain and its repressive legal framework. Current Spanish laws, such as the organic law 4/2015 (commonly known as the «gag law») and the spanish penal code retain a restrictive approach of the cannabis regulation.

This decision is a call for legislative reform that is better adapted to the contemporary uses of cannabis and individual freedom.

Beyond the penal implications, this decision also opens up a wider debate on administrative sanctions in Spain for cannabis possession. In many cases, consumers are fined without a proper analysis of the substance. THC content of substances seized

Since administrative tests are often unable to quantify THC levels, fines are imposed even when the substance contains less than the legal limit. THC threshold of 0.3 % set by the Supreme Court to define psychoactive products.

Supporters of the reform argue for a more rational approach, suggesting that the personal possession and CBD-rich products be explicitly decriminalized or, at the very least, regulated by a clearer legal framework.
