The drug impaired driver. Detection and forensic specimen analysis.

Whole blood samples were collected from arrested D. U. I. subjects in two locations, by the U. S. Park Police (USPP) in and around Washington, D. C. and through a suburban police department (MLMP), for the purpose of detecting illicit drug use. All blood samples were screened using an adapted Abuscreen RIA to non-urine (blood) procedure for the following drugs: THC, Cocaine, PCP, and Opiates. Forensic samples were confirmed through GC/MS. Results and characteristics of drug offenders are presented. It was found that 39 percent of sampled offenders from the MLMP showed measurable levels of cannabinoids. 9.5 percent of sampled offenders from the USPP showed measurable levels of Phencyclidine. Recommendations are made for the processing of suspected drug impaired drivers.
