How to Find Addiction Treatment Centers in Boerne, Texas That Can Handle Cases of Prescription Drug Addiction?

I have a friend who happens to be addicted to sleeping pills. It started out as a need because she’s insomniac, but for some reason, she has found a way to experience euphoria from use of the drug. She buys a lot and when I asked her what she uses it for, she even cajoled me to try. I would like to find an addiction treatment center so I can find out more information about this kind of addiction and maybe then I can get someone to talk to her about her condition.
