Randomly selected drivers were stopped at times and places of previous fatal crashes in Lincoln, Nebraska, and Dade County (Miami), Florida. Breath, urnine, blood, and lip swab samples were requested, for later analysis for drugs and medications. A cooperation rate of 78% was achieved for most aspects of the survey, and slightly less for obtaining a blood sample. Overall, 1,029 urine samples and 840 blood samples were collected and analyzed. About 3% of the Lincoln drivers and 2% of the Dade County drivers evidenced one or more of the 41 drugs tested in the blood or at concentrations of 1 ug/ml or more in the urine. At least a trace amount was confirmed in about 4.3% of each driver group. Sedatives, particularly phenobarbital, were the most commonly found drugs. In addition to the drugs, marijuana traces were found on the lip swabs of 3% of the Lincoln drivers and 9% of the Dade County drivers. The living driver findings were compared with similar results from fatally injured drivers, obtained under a previous contract. The comparison indicates that users of drugs are about four times as likely to be fatally injured in a vehicular crash as nonusers. /AUTHOR/
