DRUG TOXICOLOGY DASHBOARD

 

This dashboard (above) shows trends with screenings, positive results, and polydrug toxicology, or drug testing results that show individuals tested positive for more than one drug.

DUI cases that matched with a drug toxicology report are shown in this dashboard (above). DUI cases without a corresponding toxicology match may reflect suspect testing refusals or limitations with data linking methods used. The following table represents the rates of toxicology matching per year:
