AbstractThis analysis is based on a follow-up study of 48 White male young adults who had been former youth multiple drug abuse patients in day-care treatment. For the most part, these respondents came from middle-class homes. As youthful offenders, many had been sent into treatment as an alternative to incarceration. Approximately six years after terminating their day-care treatments, interview data were collected when most were in their middle twenties. Consistent with previous research, those consuming more drugs were found to be more likely to have resisted treatment, to have trouble with the law, to have poorer work histories and diminished educational attainments, and they showed evidence of poorer psychological health. Surprisingly, the data also indicated that high-volume drug users were more likely to be living in their parental homes, compared to those whose drug use patterns were more moderate. It is suggested that the pattern of taking up residence with one's parents while drug dependent may be encouraged by parental enabling. The implications of these findings for guiding efforts in substance abuse treatment are discussed.
