Is there any drug treatment programs available in Rosholt, South Dakota?

I’m looking for a list of different drug treatment programs in Rosholt, South Dakota because I want my cousin Nick to undergo treatment. He has been addicted to crystal meth for almost a year now and I know that I have to intervene with his addiction. Please help me find a great drug treatment program that will help Nick recover from all of this madness. Please, please… I’m his only hope.
