Modeling the longitudinal impact of legal sanctions on narcotics use and property crime

Structural equation models are used to confirm the suppressive effects of legal sanctions, e.g., probation and parole, on narcotics use and property crime. Both concurrent and longitudinal effects of legal sanctions are tested within two different models, which together span the entire addiction career. The findings indicate that (1) the suppressive effects of legal sanctions are evident only when legal sanctions are operationalized as parole or probation officer contact where urine monitoring is utilized; (2) only concurrent suppressive effects are statistically significant, and longitudinal suppressive effects are not; (3) both narcotics use and property crime are suppressed by legal sanctions, although the latter is less responsive than the former to intervention by the criminal justice system; and (4) suppressive effects tend to be more pronounced later in the addiction career. The significance of the findings and the implications for criminological theory related to issues regarding surveillance effects are emphasized.
