Halfway houses for alcohol and drug abusers provide a structured, supportive residential program for individuals who are considered to be at risk for post-treatment failure. This study examines 641 former residents of eight programs to determine whether positive outcomes are attained following halfway house placement. Results indicate that, during the 14 months following placement, these individuals exhibit fewer admissions to the Detoxification Center, less dependence on public assistance, less involvement with the criminal justice system, and are more often employed and abstinent than during the 14 months prior to placement.
