Long Term/In House Drug Treatment Referals PLz!?

I am looking for a long term in house drug treatment program for my step father. He does not have insurance and has been doing drugs for over thirty years and is broke! I have been searching for free treatment options but cant find any. I remember months ago I gave a donation to a treatment center that had people at wal-mart. It was free and it was in house and long term but I lost the brochure and dont remeber the name
