Are There Programs Available for the People of Lewiston, ME Who Are Seeking Drug Treatment?

I have no idea about drug rehabs or drug treatment programs. I’m looking for a facility which offers treatment for drug users like my sister. She parties a lot and she takes a lot of club drugs. I’m worried about her health. I want to accompany her to a rehab or something to get treatment but I don’t know if there’s a rehab facility in Lewiston.
