Free Addiction Help in San Antonio: Where to Start, Free Detox, and How to Help Someone Who Is Homeless
Joint Commission accredited · In network with most major insurance · Admissions answered 24 hours a day
Published October 14, 2026
Free addiction help in San Antonio exists, and most of it runs through one public agency: The Center for Health Care Services, Bexar County’s local mental health and substance use authority. It runs the state’s front door for treatment, a 24-hour helpline, and its own detox program. This page explains where to start, what is free or charged on a sliding scale, how to help someone who is living on the street, and where a private detox center like Briarwood fits in.
Where do you start for free addiction help in San Antonio?
Start with the OSAR program at The Center for Health Care Services, 210-261-3076. It is the state-funded entry point for anyone in Bexar County and 27 surrounding counties who wants substance use treatment.
OSAR stands for Outreach, Screening, Assessment and Referral. Texas Health and Human Services runs one in each region of the state, and the only requirement is living in Texas. OSAR screens you, works out what level of care fits, and refers you into state-funded programs, including detox, residential treatment and outpatient care.
If it is late at night or you are in crisis, call the center’s 24-hour crisis and substance use helpline instead: 210-223-7233 or 800-316-9241. For a medical emergency, call 911.

Is there free detox in San Antonio?
Yes. The Center for Health Care Services runs a residential detox program at The Restoration Center, 210-246-1360, and says no one is denied services because they cannot pay.
The center’s charges are set on a sliding fee schedule based on household size and income. It also says it does not turn people away because they are covered by Medicaid, Medicare or CHIP. That makes it the main option for someone with no insurance or with Medicaid, who would otherwise struggle to find a detox bed.
The same building runs other services that matter after detox:
- Outpatient and intensive outpatient treatment, after an assessment, for people with a substance use disorder
- Opioid Addiction Treatment (OATS), medication treatment for opioid addiction, at 210-261-3001
- A public sobering unit, a medically safe place for people who are intoxicated in public, offered instead of arrest
Waiting lists and eligibility change, so call ahead. OSAR can tell you where a bed is open.

How do you help a homeless person with an addiction in San Antonio?
Start with what they need right now, offer a call to the crisis line together, and connect them with Haven for Hope, San Antonio’s low-barrier shelter campus. A safe place to sleep makes treatment appointments easier to keep.
If they are in danger, call 911. That includes someone who is unresponsive, having a seizure, very confused or struggling to breathe. Withdrawal from alcohol can be dangerous, and an opioid overdose can kill within minutes.
Ask, do not lecture. Water, food, a ride, or a phone to use are good openers. Offer choices, not demands. If they agree, call the crisis line on speaker so they hear the options themselves.
Connect them with Haven for Hope. Its south campus offers safe, low-barrier indoor sleeping, and its north campus offers longer-term services for individuals and families. The main office is at 1 Haven for Hope Way, 210-220-2100.
Use the services on the same campus. The Center for Health Care Services runs an Integrated Treatment Program at Haven for Hope, 210-261-1440. It is a residential recovery program for men and women experiencing homelessness, mental illness, trauma or substance use.

Outpatient Drug & Alcohol Detox in San Antonio
What if the person uses opioids or fentanyl?
Carry naloxone. It reverses an opioid overdose, and since 2023 the nasal spray has been sold without a prescription, so anyone can buy it at a pharmacy.
Fentanyl turns up in street drugs and in counterfeit pills made to look like prescription medicine. The DEA seized more than 47 million fentanyl-laced fake pills in 2025, and says two milligrams can be a deadly dose. Someone who has stopped using for a while, after jail, a hospital stay or detox, is at the highest risk. Their tolerance has dropped, and a dose they once handled can now kill.
If you find someone not breathing, call 911, give naloxone, and stay with them. A second dose may be needed. The fentanyl detox page explains the treatment options, including medication.

When does private insurance open more options?
If you have private insurance through an employer or the marketplace, TRICARE or VA benefits, private detox centers become an option too. Briarwood is one of them.
Briarwood runs outpatient detox in San Antonio, at 6707 W Hausman Rd. It means scheduled medical visits with no overnight stay, and it fits people whose withdrawal is expected to be mild or moderate. The clinic is open Monday to Friday, 8:00am to 10:00pm, and admissions answers 24 hours a day, in English and Spanish. For care through the night, Briarwood runs inpatient detox in Austin and Houston.
Briarwood does not accept Medicaid or Medicare, and it is not free. For someone with no insurance or with Medicaid, The Center for Health Care Services is the better first call. A free benefit check takes about two minutes and tells you what your plan covers.
The 24-hour detox in San Antonio page explains what is open at night. The San Antonio intensive outpatient program is the usual next step after outpatient detox.
