Living near others can be challenging, especially when issues like cannabis consumption arise. While marijuana use has been decriminalized or regulated in many places, it can still cause disturbances among neighbors due to the smell or smoke. But can you report a neighbor for smoking cannabis? In this article, we analyze Spanish legislation and the possible actions you can take.
Cannabis use legislation
The regulation of cannabis in Spain has been a topic of debate for years, particularly as laws and regulations surrounding its use have evolved. Although cannabis use and possession have been decriminalized in many cases, the disturbances it can cause, such as strong odors or smoke, remain a significant concern for neighbors. If you live in a shared residential building and are bothered by a neighbor smoking cannabis, do you have the right to take action?
What does the law say about private spaces?
In Spain, cannabis laws are complex, and the rules vary depending on whether the use occurs in private or public spaces. Here is what the law specifies:
Consumption in private spaces
Law 4/2015 does not directly regulate cannabis consumption in private spaces (i.e., inside a home), provided it does not directly disturb public order. This means that a person cannot be penalized for using cannabis in their own home unless their actions disturb or harm others in their immediate surroundings.

However, if private cannabis use causes disturbances such as excessive noise, smoke, or odors that bother neighbors, the issue could be addressed through other legal channels. In these cases, residential laws, such as the Horizontal Property Law or the community regulations, might apply to resolve disputes arising from coexistence.
Consumption in public spaces
Cannabis use in public areas is prohibited in Spain. While not a criminal offense, it can lead to administrative penalties such as fines. Local authorities may issue fines for public consumption, especially if it disrupts public order.
Consumption in residential communities
Cannabis use within apartment buildings or shared residential spaces can be more problematic. If the use generates disturbances like smoke or odors that interfere with others’ rights, it could be considered a violation of coexistence rules. In such cases, even if the consumption occurs in a private space, the community may intervene if it affects others’ quality of life.
Disturbances caused by a neighbor smoking cannabis
Smoking cannabis can cause various disturbances that may affect other neighbors. The most common complaints include:
- Odor: Cannabis has a particular, strong, and persistent smell that can easily seep through walls, ventilation ducts, or windows. Knowing how long cannabis odor lingers in a room can be helpful. For non-users, the smell can be unpleasant and disruptive. In such cases, using an odor eliminatos can be an effective solution.
- Smoke: Even when cannabis is consumed indoors, the smoke can spread to other areas, especially in older buildings with poor ventilation. This can be problematic for individuals with respiratory issues or sensitivity to smoke.
- Health impact: People with asthma, allergies, or other respiratory problems may be particularly affected by cannabis smoke. In some cases, smoking inside an apartment could be seen as a potential health hazard to others.
- Noise and related behaviors: Cannabis use may sometimes be associated with social gatherings, noise, or behaviors that disrupt neighborhood peace. Although these issues are not directly related to cannabis consumption, they can be indirect consequences.
Can you report a neighbor for smoking cannabis?
If a neighbor’s cannabis use is causing disturbances or affecting your well-being, you cannot report them solely for smoking. However, depending on the situation, there are legal and non-legal options you can consider.
Laws on cannabis use and possible actions to take
Here are some legal options for addressing potential conflicts with a neighbor who smokes cannabis:
Legal possibilities
Although cannabis use in private spaces is decriminalized, if it creates disturbances for other residents, it may fall under administrative violations. The law specifies that cannabis use should not infringe on others’ coexistence or rights.
If cannabis smoke or odor seeps into shared building areas or affects other residents, it could be a violation under the Horizontal Property Law. Article 7 of this law states that property owners must respect the “peace and well-being” of the community, and any behavior causing continuous disturbances can be penalized.
Actions to take
If cannabis-related disturbances persist and affect your quality of life, there are several legal actions you can consider:
- Direct communication: Start by speaking with your neighbor politely to explain how their cannabis use is affecting you. Often, a simple conversation can resolve the issue without escalating it further.
- Formal complaint to the community association: If direct communication does not work, you can file a formal complaint with the community association. If the issue persists, the association may decide to convene a meeting to address the matter.
- Legal recourse: If the problem continues and becomes a significant source of conflict, you can take legal action. Courts may evaluate whether the disturbances are ongoing and issue a resolution requiring the neighbor to cease their behavior. This could include fines or, in extreme cases, an order to stop cannabis use in their private space.

Police intervention
In more extreme cases, if cannabis use leads to serious disruptions to public order or community coexistence, the police may intervene. Authorities could issue penalties for violating coexistence regulations or creating disturbances for other residents.
Other non-legal solutions to consider
If cannabis use is not legally punishable but remains a nuisance, there are also non-legal solutions to explore:
- Use odor-neutralizing products: If the primary issue is the smell, products like air purifiers, deodorizers, or filtration systems can help reduce the impact of cannabis odors in your home.
- Neighborhood mediation: If direct conflict resolution fails, many residential communities offer mediation services. These are designed to resolve disputes without resorting to legal action.
- Reinforce your home’s protection: Ensure that your windows, doors, and ventilation systems are adequately sealed to prevent smoke or odors from seeping into your home.
Although cannabis use in private spaces is legal in Spain, if it causes disturbances to others, you may have grounds to report a neighbor for smoking cannabis. However, it is advisable to explore alternative solutions first.
