“…For example, drug dependence is a chronic medical illness (McLellan, 2002; McLellan, Lewis, O’Brien, & Kleber, 2000), and younger participants may be in need of a more intensive level of care because they may be earlier in their drug use careers and have had fewer substance abuse treatment episodes. Individuals with SUDs often need multiple treatment episodes in order to reduce the likelihood of relapse and/or recidivism (Booth, Staton, & Leukefeld, 2001; Lundgren, Sullivan, & Amodeo, 2006; Oser et al, 2009); therefore, those who only received outpatient treatment before prison entry, but relapsed and became involved in criminal activities might need a more intensive treatment plan both during and after incarceration. A negative relationship between legal employment and drug use severity has consistently been documented in the literature (Webster, Staton-Tindall, Duvall, Garrity, & Leukefeld, 2007; Wolkstein & Spiller, 1998).…”
