I Need to Know if There Are Any Drug Rehabs in Brownwood, Texas That Will Take People With Dual Diagnosis.?

My friend has a brother whom she thinks has dual diagnosis. She knows for a fact that he does heroin, but she’s not sure if he’s really depressive. Their parents are away, and she’s asking me to help her find a rehab for him because she thinks this would be the best thing to do for her brother. She’s bent on finding one that will take patients with dual diagnosis, as she says that they’re better equipped at handling patients with even just a slight psychological problem.
