Is it possible to petition the courts in New york State to mandate someone to a drug rehab .?

I have an adult son who is using drugs daily and refuses to consider rehab. I need to know if I can petition the courts to place him against his will. He's a danger to himself and has been hospitalized many times because of his use of Angel Dust. He's a danger to himself.
