No, particularly not in urine. You cannot correlate pharmacological effects in the body with what you find in the urine. So we're corroborating the finding. Based on the clinical indicators and the problem the person has in completing divided attention tasks, we can say they are under the influence of a drug, or drugs. What the lab does, or what a toxicologist does, is corroborate that finding and says the DRE evaluator says it looks like this person is under the influence of a central nervous system stimulant. I will analyse the urine sample and I'll find cocaine, and cocaine is a central nervous system stimulant; therefore I can corroborate their findings.
