In response to the increasing numbers of criminal offenders involved with d
rugs, the criminal justice system has sought more effective means of interv
ening with these offenders. One intervention approach is Treatment Alternat
ives to Street Crime (TASC), an offender management model that has been imp
lemented in various forms since the early 1970s. TASC facilitates treatment
for drug-using offenders as part of an overall strategy to control drug us
e and associated criminal behaviors. This article reviews the evolution of
TASC and reports findings from an evaluation of five TASC programs. The eva
luation, experimental at two sites and quasiexperimental at three, found fa
vorable effects of TASC programs on service delivery and offenders' drug us
e. Findings on criminal recidivism were mixed and difficult to interpret. T
his article concludes with specific recommendations for improving TASC and
similar programs within the criminal justice system.
