“…Research in the Riverside, California, drug court, for example, found that being White, being self-supporting, and prior marijuana use were predictors of successful graduation (Sechrest & Shicor, 2001). Hohman, McGaffigan, and Segars (2000) found that those who completed the San Diego-based drug court were more likely to be women, had not used drugs 30 days before program admission, had fewer prior treatment experiences, remained in the program longer, and had employment and stable housing by time of completion. Roll, Prendergast, Richardson, Burdon, and Ramirez (2005) identified two significant outcome predictors in a southern California drug court; participants employed at the time of admission were more likely to complete the program and participants with a history of intravenous drug use were less likely to graduate.…”
