Houston Substance Abuse Clinic

Houston's 731 public health clinic listings don't spread evenly across the city. One ZIP alone holds 18 entries, another has 10, and a third has 9, showing a real cluster of clinics in that stretch of town. Several smaller ZIPs each carry 5 or 4 listings, filling out the rest of the map. If you're hunting by neighborhood, checking a handful of nearby ZIPs together often turns up more options than searching just one. Contact info varies in completeness too: 705 listings show a phone number, but only 460 list a website, so calling ahead beats waiting on a site that might not load.

Paid placements on this page carry a Sponsored label, and none are active in this Houston category right now, so every clinic here appears through the same plain directory listing, not a bought slot. If you run one of these clinics and the phone number's wrong or the website's gone stale, you can claim the listing and update it so patients find accurate info. Always confirm current hours and services directly with the clinic before visiting.
