Sixty-one participants in outpatient therapy for cocaine dependence provided urine samples and self-reports of cocaine use 3 times a week for 4 weeks. Participants later gave a retrospective self-report of cocaine use for the month on the addiction Severity Index (ASI). Comparisons with urine test values revealed substantial underreporting of cocaine use on both measures, and results from the 2 forms of self-report were only imperfectly correlated. More participants admitted to at least 1 cocaine use episode on the ASI than on the repeated self-reports, but the repeated reports provided a more accurate index of the relative frequency of cocaine use during the month. Self-reports can enhance cocaine use detection when urines are infrequently collected and can help determine whether consecutive positive urine samples represent elevated metabolite levels from a single drug use episode. However, self-reports cannot substitute for regular urine sampling.

D003042	Cocaine	An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.

D016231	Fluorescence Polarization Immunoassay	Fluoroimmunoassay where detection of the hapten-antibody reaction is based on measurement of the increased polarization of fluorescence-labeled hapten when it is combined with antibody. The assay is very useful for the measurement of small haptenic antigens such as drugs at low concentrations.
