What Is an Annex in Mexico? History, Regulation, and Risks
An "anexo" in Mexico is a rehabilitation center for people with addiction problems, typically based on community support and recovery programs like Alcoholics Anonymous. Many anexos emerged as community initiatives to help individuals with alcoholism or drug addiction when public treatment services were almost nonexistent. Today, different types of centers exist: some function as recovery homes run by people in sobriety, while others have evolved into clinics with professional staff and health supervision.
If you have looked for information about addiction treatment options for a family member in Mexico, you have likely heard the word "anexo." You probably also aren't entirely sure what it means, how it differs from a clinic or a hospital, or if it is safe.
This article explains what anexos are, how they originated, how they are regulated—or not regulated—and why their existence generates so much debate in Mexico. It does not intend to promote or condemn them, but rather to offer clear and objective information so that families and professionals can make informed decisions.
1. Origin of Anexos in Mexico
Anexos were not born as an official health system. They emerged communally, mainly from the 70s and 80s, in working-class neighborhoods of cities like Guadalajara, Mexico City, and Monterrey, in a context of a profound scarcity of public addiction treatment services.
Their original model was strongly influenced by Alcoholics Anonymous (AA) groups and their local variants such as Neurotics Anonymous and Narcotics Anonymous. The logic was simple: people who had already gone through the recovery process opened their homes or premises to receive those who needed help, offering containment, fellowship, and spirituality as central tools.
Three factors explain their proliferation:
• The historical insufficiency of public treatment offerings. Mexico never built a broad network of specialized, free-access centers for addictions.
• Low cost. Traditional community anexos operated at a very reduced price or completely free of charge, financed by donations or minimal fees.
• Family desperation. Faced with the absence of immediate alternatives, many families opted for these options without having sufficient information about what was happening inside.
The term "anexo" in this context does not have an official origin. It became colloquially popular to refer to these community recovery spaces, distinct from formal hospitals or clinics.
2. Difference between an anexo and a rehabilitation clinic
In Mexico, different types of centers for addiction treatment coexist, and the differences between them are important:
Community Anexos
These are the original model. They operate under principles of self-help and informal therapeutic community, generally run by people in recovery without certified clinical training. They usually use group dynamics, work, routine, and spirituality as pillars of treatment. Not all of them have doctors, psychologists, or social workers on their staff.
Private Rehabilitation Clinics
These are establishments that, at least in theory, must meet minimum requirements for infrastructure, staff, and procedures. In Mexico, this implies registering with COFEPRIS or the corresponding state body (COEPRIS in some states), having health personnel, and operating under the Official Mexican Standard NOM-028. In practice, the gap between what the standard says and what happens in many centers is considerable.
Psychiatric Hospitals
These are specialized medical establishments that treat mental disorders, including substance use disorders with comorbidities. They require specialized medical personnel (psychiatrists, nurses), hospital facilities, and authorization from the Ministry of Health. They are the most regulated level of care, but also the least economically accessible for most of the population.
The line between an anexo and a private clinic is blurred in Mexico. Many centers call themselves clinics without meeting the minimum requirements, while some anexos have progressed in their professionalization. The name does not guarantee the quality or legality of the service.
3. How anexos are regulated in Mexico
The regulation of addiction treatment centers in Mexico primarily falls under NOM-028-SSA2, the Official Mexican Standard for the Prevention, Treatment, and Control of Addictions. This standard establishes the minimum criteria that establishments providing care to people with substance use disorders must meet.
Among the requirements included in NOM-028 are:
• Registration and authorization with the corresponding health authority.
• Having a medical director or technical manager with recognized training.
• Maintaining clinical records for each user.
• Having documented care protocols.
• Guaranteeing minimum living, food, and hygiene conditions.
The monitoring and verification of compliance with this standard correspond to the Federal Commission for Protection against Health Risks (COFEPRIS) at the federal level, and to the State Commissions for Protection against Health Risks (COEPRIS) in each federative entity. However, the actual supervisory capacity varies enormously from one state to another.
The practical consequence is that many centers operate without registration or with expired registrations, and inspections are irregular and insufficient for the magnitude of the phenomenon.
According to data from the National Council against Addictions (CONADIC), there are thousands of treatment centers in Mexico, a significant portion of which operate outside the current regulatory framework.
4. Common problems in the system
The combination of high demand, insufficient public offerings, and weak supervision has created conditions in which serious problems have been documented in part of the anexo system:
Involuntary commitments
One of the most serious and widespread problems is the admission of people without their consent, informally known as 'levantón' (forced pickup). Family members bring the person in an addiction situation, sometimes with the collaboration of people from the center itself, without any legal process or clinical evaluation. This constitutes a violation of fundamental rights recognized by national and international human rights organizations.

Lack of qualified staff
In many centers, care is exclusively in the hands of people in recovery without clinical training. While lived experience can be a valuable resource in accompaniment processes, it does not replace the ability to detect psychiatric comorbidities, manage crises, or supervise medically risky detoxifications.
Precarious living conditions
Some documented complaints by organizations like the National Human Rights Commission (CNDH) have pointed to overcrowding, deficient food, restriction of communication with family members, and the use of questionable physical or disciplinary containment measures.
Lack of post-treatment follow-up
Most centers lack structured follow-up protocols once the internment is completed, which limits the possibilities of consolidating the progress made during the treatment period.
5. Why they continue to exist
Despite the documented problems, anexos continue to be an option resorted to by thousands of families in Mexico every year. This is not an accident or irrationality: it responds to structural factors that have not been resolved.
Absence of accessible public alternatives
Mexico does not have a sufficient network of public and free treatment centers to cover the demand. The Primary Care Centers for Addictions (CAPA) have limited coverage and, in many cases, waiting lists or low-intensity services. Public psychiatric hospitals, which are overcrowded, rarely have capacity for addiction inpatient treatment without severe psychiatric comorbidity.
Family desperation
When a family is in crisis due to a member's addiction and cannot find quick and accessible options, the threshold for seeking help drastically lowers. An anexo that accepts today, charges little, and is close to home may seem like the only way out. This desperation is also the driving force behind the clinical debate about involuntary commitment—a debate that goes far beyond the law.

Cultural acceptance and referral networks
In many communities, anexos are part of the social landscape of recovery. Word-of-mouth recommendations from neighbors, friends, or self-help group members generate a social legitimacy that does not depend on the formal regulatory framework.
The community model works for some of its users
It cannot be ignored that there are people who attribute their recovery to their time in an anexo. Structure, peer interaction, routine, and a sense of belonging are elements supported in recovery literature. The problem is not that these elements lack value, but that in unsupervised contexts they can coexist with abusive practices.
6. Are all anexos the same?
No. This is perhaps the most important distinction that can be made on this topic, and the one most often omitted in public debates.
Talking about "anexos" as if they were a homogeneous phenomenon leads to generalizations that help neither families seeking information nor professionals working in this field. There are at least three very different realities under that same label:
Centers with abusive practices
These are the ones that have generated the most serious complaints: involuntary commitments, physical or psychological mistreatment, unsanitary conditions, and a total lack of professional supervision. These cases have been documented by the CNDH, media, and human rights organizations, and represent a serious problem that should not be minimized.
Community Recovery Homes
These are centers that, although they do not meet all formal requirements, operate with clear principles of community, respect, and mutual support. They have rules of coexistence, are led by people with recovery experience, and do not resort to coercive practices. Many have active links with AA groups or other recovery communities.
Centers in the process of professionalization
In recent years, some centers operating under the traditional anexo model have initiated formalization processes: they incorporate certified psychologists or counselors, work to obtain registration with the health authority, and adopt evidence-based protocols. These spaces represent a bridge between the community model and clinical practice.
The category a center falls into is not always evident from the outside. The following section offers concrete criteria to evaluate an establishment before making a decision.
7. How to know if a center is legal and reliable
Before admitting a family member—or oneself—to any treatment center in Mexico, it is important to verify a series of aspects. None alone is sufficient, but together they offer a clearer picture of the quality and legality of the establishment.
Step 1: Verify registration with the health authority
Every addiction treatment center must be registered with COFEPRIS or the corresponding state COEPRIS. The registration number can be requested directly from the center. A legally constituted institution will have no problem showing it.
Step 2: Ask about the health staff
A minimally regulated center must have a responsible doctor or psychiatrist, as well as health personnel. If the answer is that "everyone is in recovery" without any integrated health professional, this is a red flag.
Step 3: Request to see the facilities
A reliable center will allow a prior visit before admission. If they refuse to show the facilities, that is a red flag. During the visit, it is important to observe the conditions of habitability, hygiene, and privacy.
Step 4: Ask about the admission process
A center that respects people's rights does not accept admissions without the user's consent. If the center normalizes or facilitates admission without consent, it is not an ethical establishment.
Step 5: Review the treatment plan
While not all centers have the same resources, they should be able to clearly explain the treatment process, how long it lasts, what activities it includes, and how progress is evaluated. The total absence of a structured plan is a red flag.
Step 6: Verify the family communication policy
Centers that completely prohibit contact with family members for extended periods without clear clinical justification should be evaluated with caution. Communication with support networks is generally a positive therapeutic element.
Frequently asked questions about anexos in Mexico
What is an anexo in Mexico?
An anexo is a rehabilitation center for people with alcohol or drug problems. Many emerged as community initiatives based on mutual aid groups like Alcoholics Anonymous, and not all function as formal medical clinics.
Are anexos legal in Mexico?
Addiction treatment centers must comply with requirements established by NOM-028-SSA2 and be registered with health authorities such as COFEPRIS or COEPRIS. However, in practice, many centers operate without registration or with limited supervision.
What is the difference between an anexo and a rehabilitation clinic?
A traditional anexo usually relies on community support and the experience of people in recovery. In contrast, a rehabilitation clinic generally has doctors, psychologists, and structured clinical protocols for addiction treatment.
Can someone be committed to an anexo without their consent?
Current mental health legislation states that treatment must be voluntary and with informed consent. However, in practice, cases of involuntary commitment still exist, which has generated legal and ethical debate in Mexico.
How to know if a rehabilitation center is reliable?
Before choosing a center, it is advisable to verify that it has health registration, qualified health personnel, clinical records, adequate facilities, and a clear treatment plan. It is also important to be able to visit the place before admission.
Do anexos work for treating addiction?
Some people attribute their recovery to their experience in an anexo, especially due to the daily structure, peer interaction, and community support. However, the quality and safety of centers can vary greatly, so it is essential to be informed before making a decision.
Final reflection
Anexos are part of the reality of the addiction care system in Mexico. They are neither good nor bad by definition. They are the result of decades of unresolved need, community initiative, state absence, and, in some cases, opportunism or abuse.
Understanding them precisely—without romanticizing or demonizing them—is essential for making informed decisions. Families seeking help deserve real information, not simplifications. And professionals working in this field need to know the ground they are operating on.
