Validity of Self-Reported Drug Use in Chronic Pain Patients

Abstract

A significant percentage of CPPs appears to provide incorrect information on current illicit drug use. Urine toxicology studies may have a place in the identification of drugs for which incorrect information may be provided by CPPs. There are many possible reasons, such as assay error, that could lead to apparent misinformation. In the clinical setting, these possibilities should be considered if urine toxicology results appear to be incongruent with psychiatric examination drug use self-report.
