Substance Abuse Programs

The Metropolitan Assessment and Treatment  is a social model program providing detoxification services to Bernalillo County residents in need of such services.

People participate in the MATS detox services on a voluntary basis. All services provided and information received are confidential. Services are delivered 24 hours a day, 7 days a week. 

To be admitted to the program, participants must be a Bernalillo County resident or homeless, 18 years of age or older and be in need of detoxification from alcohol or dual substances. 

If the drug used is methadone and the use is more than 30 mgs, the person cannot be admitted. If the drug used is heroin, alcohol, cocaine and the person has not used within the last three days, the person cannot be admitted unless symptoms are presenting.

If the person is on any life-sustaining prescription medications (such as insulin for diabetes), must have the prescription medication with them. (Note: If the person is on psychiatric drugs but does not have the medication with them, the person can be admitted if not presenting and seems stable). 

The person also:

  • Must not have any restraining orders or warrants for arrest.
  • Must not have any appointments within the next 24 hours and up to the next 3 - 5 days. Admission to these services would most likely prevent the person from making that appointment.
  • Must  be mobile or able to move without assistance from others. 

People who would not be able to be admitted to MAT detox include:

  • Any person who is violent, has outstanding warrants, or otherwise needs a secure holding facility, or who has a no-contact restraining order against them.
  • Any person who is under the age of eighteen (18) years.
  • Any person who is the subject of involuntary commitment proceedings or detention without a hearing
  • Any person who requires specialized care not available at the facility.
  • Any person who has a physical or medical condition that is unstable or can only be safely treated in a hospital. 
  • Any person who can be safely maintained and effectively treated in a less restrictive or intensive level of care.
  • Any person who does not voluntarily consent to admission or treatment. 
  • Any person needing assistance with activities of daily living. 
  • Individuals who have previously been to MATS Detox and have been discharged for administrative reasons may not be re-admitted for certain time periods.​
