How will I get to find substance abuse treatment centers in Lincolndale, New York?

I need to do this for my friend. Among the two of us, she has always been the more responsible one. She looked after me as if I was her little sister. Ever since her boyfriend broke up with her, though, things changed. I would often find her slumped on her bed whenever I visit her house. She hid it from us, but she has also been indulging in alcoholic beverages as well. I sat beside her all day yesterday. We reminisced and cried, and she finally agreed to get herself treated for her alcohol addiction. This is why I need to find substance abuse treatment centers. Any help will be surely appreciated.
