Abstract
Urinalysis is utilized routinely as a tool to validate self-reported drug use. Past research has been inconclusive, however, in confirming strong correlations between urinalysis and self-reported drug use. In the current study, correlation estimates for cocaine and heroin use are derived from adult arrestees surveyed through the Arrestee Drug Abuse Monitoring (ADAM) Program between 1990 and 1997. While the strength of agreement between urinalysis and self-report data varies by both substance and jurisdiction, correlation estimates are consistent over time. These findings suggest that the need for urinalysis should be reassessed.
