CBI Toxicology Dashboard

The Colorado Bureau of Investigation Toxicology Dashboard provides recent findings on drug and alcohol screening of suspected impaired drivers during the previous 18 months. This dashboard includes data on individuals arrested on suspicion of impaired driving for whom charges were or were not subsequently filed. The dashboard data were analyzed by the Office of Research and Statistics based on blood samples submitted by law enforcement agencies for toxicology testing to the CBI Forensic Services Toxicology Laboratory. The CBI Toxicology Dashboard should not be compared to the toxicology data in the ORS: Impaired Driving Dashboard (above) due to differences in the reporting methods. For additional information on the differences in reporting methods, impaired driver types, reporting periods, and limitations of this separate CBI toxicology analysis, please see the "Data Notes" on the CBI Toxicology Dashboard.
