Major findings from this report include: in 2008, there were 527 faith-based substance abuse treatment facilities or facilities affiliated with a religious organization that were not located in or operated by a hospital; as of March 31, 2008, an average of 74 clients were enrolled in faith-based facilities compared with an average of 88 clients enrolled in non-faith-based facilities; 24.1 percent of faith-based facilities provided a halfway house or other transitional housing, compared to 10.4 percent of non-faith-based facilities; and 10.6 percent of faith-based facilities provided free treatment to all clients, as compared to 3.4 percent of non-faith-based facilities. This National Survey of Substance Abuse Treatment Services (N-SSATS) Report examined the characteristics of substance abuse treatment facilities in the United States in 2008, and compared faith-based and non-faith-based facilities that were not affiliated with hospitals. Other findings from the report include: all faith-based facilities were privately operated, with 93.9 percent operated by a private non-profit organization; 33 percent of faith-based facilities were located in the Midwest; faith-based facilities were more likely to focus primarily on providing substance abuse treatment services, and were more likely to offer non-hospital residential treatment. These and other findings indicate that faith-based substance abuse treatment facilities are an important part of the substance abuse treatment system, and their willingness to offer free treatment to persons who cannot afford it fills a gap in access to treatment for substance abusers.
