“…Additionally, Simpson, Savage, & Joe (1980) found that treatment-naRve clients were less likely to enter substance abuse treatment during a 3-year follow-up period than treatment-experienced clients, suggesting that a prior treatment history was associated with higher rates of relapse. Finally, several studies have found that prior treatment for opiate addiction is associated with continued drug use (Brewer, Catalano, Haggerty, Gainery, & Fleming, 1998) which seems at odds with prior treatment experience being associated with longer lengths of stay in OMT (Maddux et al, 1994;Simpson & Joe, 1993).…”
