A follow-up of admissions to the California Civil Addict Program.

A follow-up interview study of early admissions to the California Civil Addict Program found that those continuing in the program performed substantially better during the commitment period than did a comparable group discharged shortly after admission. To a lesser extent, the program also appeared to have had some impact subsequent to discharge. Those program discharges defined as successes tended to do relatively well until the time of interview. Comparisons under the strict (pre-1970) and more lenient regimens showed roughly comparable behavior, but the availability of methadone maintenance was also a significant factor in reducing heroin use during the latter period.
