Book excerpt: Treatment Alternatives to Street Crime (TASC) provides an objective bridge between two separate institutions: the criminal justice system and the drug treatment community. Under TASC, community-based supervision is made available to drug-involved individuals who would otherwise burden the justice system with their persistent drug-associated criminality. TASC operates in more than 100 jurisdictions. Covers: empirical and theoretical foundations of TASC; early years of TASC; early TASC evaluations; the current structure of TASC; and the future of TASC. References.
