“…The policy and programmatic implications of Prop 36 have been much discussed (Appel, Backes, & Robbins, 2004; Ehlers & Ziedenberg, 2006; Klein, Miller, Noble, & Speiglman, 2004; Marlowe, Elwork, Festinger, & McLellan, 2003; Riley, Ebener, Chiesa, Turner, & Ringel, 2000; Speiglman, Klein, Miller, & Noble, 2003). Research has shown that Prop 36 has increased the number of criminal offenders accessing California’s drug treatment system (Hser, Teruya, et al, 2007; Longshore et al, 2005), many of whom were treatment-naive individuals with multiple and complex problems that were unexpectedly severe (Hser et al, 2003; Wiley et al, 2004), resulting in several systemwide impacts (Hardy et al, 2005; Hser, Teruya, et al, 2007; Niv, Hamilton, & Hser, 2009). Most offenders (about 85%) receive substance abuse treatment in outpatient drugfree (nonmethadone) settings, where their median length of stay is approximately 6 months; about 10% receive long-term residential treatment (with a median length of stay of 90 days), and relatively few (<5%) receive short-term residential or narcotic replacement therapies (Urada, Longshore, & Conner, 2007).…”
