First, the delivery system must have preliminary screening to identify potential alcohol/other drug use and related problems among youths that have contact with the justice system. Second, there must be an in-depth and broad assessment to document the nature and seriousness of alcohol-related and other drug-related problems. If indicated, an intervention or treatment plan should be developed. Where possible, communities should establish centralized receiving facilities. Third, there should be intervention/treatment options. Programs based on social learning theories, such as therapeutic communities, seem more effective in treating drug-abusing persons who have developed their drug use lifestyle over a period of years. Fourth, aftercare services are a vital link in the service continuum. Such services are typically, infrequent, underdeveloped, and narrowly focused on single problem areas. Finally, there should be long-term continuity of service. Experience shows a need to involve many troubled juveniles and their families in long-term, intensive service and supervision program to address difficulties manifested in substance misuse and delinquency. 8 references
