Is Rehab in Mexico Safe? How to Check Any Center, Including an Anexo

Anexo Mexico: an anexo is the popular Mexican name, meaning annex, for a residential house where people go for addiction. Whether rehab in Mexico is safe cannot be read from a name, a website or a price. Peer-reviewed researchers describe anexos both as community-based recovery houses and as informal places where coercion has been documented, and Mexico's national standard also regulates a mutual-help residential model, so the word names a kind of place, not a legal status. Official sources can tell you which documents an establishment should be able to show, such as an operating notice, a consent form and a signed cost agreement, and what a Mexican oversight body recorded where those were missing. They cannot tell you that any particular center is safe. This guide sets out those documents and ends with eight questions to bring. It does not name, rate or verify any center, and it is not legal or medical advice.

One word, many kinds of place

The word covers a range. Anthropologists who studied anexos in Mexico City describe them as informal residential centers that offer valuable health, social and practical support but risk adding to residents' suffering through coercive rehabilitation techniques. Another 2016 paper calls anexos community-based recovery houses created in Mexico and notes that some Mexican anexos have come under fire for coercion, confrontational methods and corporal punishment. Both are qualitative studies, so neither describes any particular center.

CONASAMA, the national mental health and addictions commission, uses the phrase "anexos o centros residenciales de atención de adicciones" in a 2024 announcement (communiqué 305, published 26 August 2024) about its supervision work. It reports more than eight thousand visits and more than 54 thousand trainings at residential centers since 2018, and its head called on these establishments to professionalize and to follow regulation grounded in human rights. So even the regulator treats the word as covering places that still need to meet the rules.

Mexico's national addiction standard, NOM-028-SSA2-2009, separates residential establishments into professional, mutual-help and mixed models and has a section on how mutual-help establishments must operate. The model changes which checks apply, and an establishment of any model is expected to hold an operating notice.

What an establishment should be able to show

The table combines the standard, the General Health Law and CONASAMA's 2024 supervision checklist. That checklist is written for mutual-help residential establishments only, so treat its items as examples of what supervisors look for, not as a legal test for every program.

What CONASAMA recognition does and does not mean

CONASAMA publishes a directory of recognized residential establishments, dated 27 August 2026. It says the directory lists establishments that follow current regulation, that inclusion reflects minimum requirements and that it is not a promotion of the centers. Treat recognition as a minimum signal and never as an endorsement or a safety guarantee. Check the legal name and address against the official record.

The directory does not say that an unlisted establishment is unlawful, and neither does this guide. A missing listing means one useful signal is absent, so ask for the other documents above.

Admission and consent: a legal question this guide does not resolve

Article 75 of the General Health Law, reformed on 16 May 2022, says internment of people with substance use conditions is a last therapeutic resort. It says internment may only be carried out voluntarily, when it offers greater therapeutic benefit than the other possible interventions, for the strictly necessary time and in the General Hospital (or pediatric hospital) nearest the person's home. Whether and how that wording reaches private residential centers is not settled by the sources this guide read. Article 75 Bis requires informed consent for any treatment or internment and says the person has the right to accept or refuse it. At the CONASAMA meeting reported in the 2024 announcement, the director of Documenta A.C., a civil-society organization, said the 2022 reform implies eliminating involuntary internments and making informed consent the basis of services. That is her reading, not CONASAMA's.

The older 2009 standard is more permissive on paper. Its numeral 5.3 says that professional and mixed establishments may admit people voluntarily, involuntarily or by mandatory order, and that mutual-help admission is strictly voluntary, with mandatory admission possible only in mutual-help establishments recognized by CONADIC. It describes involuntary admission as for people who need urgent care or pose a grave and immediate danger, requiring a physician's indication and a responsible relative's written request, with notice to the Ministerio Publico within 24 hours. It describes mandatory admission as one requested by a competent legal authority after a medical exam. The 2024 checklist also asks about mandatory admissions requested by a legal authority, and rates them as acceptable only for establishments with prior CONASAMA recognition. Do not read these 2009 conditions as authorization for a private center or a family to admit an adult against the person's will. How the 2009 standard and the 2022 statute fit together is a question for a Mexican lawyer, and this guide does not answer it. The practical point is simple: ask for the consent form and for the establishment's written admission and leaving rules before anyone is admitted.

Warning signs documented by a Mexican oversight body

The national torture-prevention mechanism of Mexico's human rights commission (CNDH) visited nine residential addiction establishments in two regions of Oaxaca. Its report says the visits took place in June and October 2021 (another paragraph of the same report says 2022), and the report is dated 25 August 2023, so the observations are older than the date suggests. It found that none of the nine had recognition from CONADIC, the earlier national addictions commission, only two had an operating notice and four had no permanent medical staff. It reported that 76.6 percent of the people interviewed said they were there involuntarily, and that people could not leave freely. It added that relatives' signed responsibility letters are not informed consent, and that an operating notice is no guarantee that an establishment is recognized by Cofepris, the federal health-risk regulator, whose supervision the report says is needed to verify minimum legal standards. It also said that some establishments operate irregularly and that no official figure exists.

This is one state, one period and a sample chosen partly because of press reports, so it does not measure Mexico as a whole or any particular center. It shows what an oversight body looked for and what it recorded when documents and consent were missing.

What the CDC adds

For any travel for medical care, the CDC advises checking the facility's credentials, notes that in some countries requirements for licensure, credentialing and accreditation may be less than in the US, warns that language barriers can complicate communication with staff, and recommends confirming what your current insurance covers abroad and getting copies of your medical records before you leave. Its page is written mainly about surgery and does not single out or rate any country, so apply it to addiction treatment only as a set of questions.

Questions to bring before anyone is admitted

1. May I see the operating notice, and does it match the legal name and address?
2. Is the establishment listed in CONASAMA's current directory, and under which name?
3. Who is the responsible manager, and which clinicians are on site by day and by night?
4. May I read the consent form and the written admission and leaving rules?
5. What are the total cost and the length of stay, in a signed agreement?
6. Which hospital receives an emergency, and who arranges the transfer?
7. How can a resident or a relative file a complaint with an outside body?
8. What follow-up exists after discharge, and who provides it?

If you think someone is in immediate danger, contact local emergency services. This guide cannot verify any establishment. The center directory can help you identify programs to examine, and each program remains responsible for confirming its current services and documents.
