“…Some studies indicate that minority groups, compared to Whites, experience better or equal access to and utilization of treatment services (Daley, 2005;Niv & Hser, 2006;Yang, Huang, & Hser, 2006), with an overrepresentation of minorities in some substance abuse treatment programs (De La Rosa, Khalsa, & Rouse, 1990;Desmond & Maddux, 1984;Hanson, 1985;Jung, 2000;Kopstein & Roth, 1998;SAMHSA, 2002;Schmidt & Weisner, 1993;Yang et al, 2006). Other evidence indicates that ethnic disparities do occur, with minorities experiencing reduced access to drug treatment (Little, 1981;Lundgren, Amodeo, Gerguson, & Davis, 2001;Rhodes et al, 1990;Robles et al, 2003;Rounsaville & Kleber, 1985;Wu, ElBassel, Gilbert, Piff, & Sanders, 2004;Wu, Kouzis, & Schlenger, 2003), fewer services (Wells, Klap, Koike, & Sherbourne, 2001), shorter treatment stays (Agosti, Nunes, & Ocepeck-Welikson, 1996;Evans, Spear, Huang, & Hser, 2006;Longshore et al, 2004;McCaul, Svikis, & Moore, 2001;Milligan, Nich, & Carroll, 2004), or complete absence of substance abuse treatment services (Longshore, Hsieh, Anglin, & Annon, 1992).…”
