“The drug test results in the Millennium Health database can be aggregated and employed to aid those involved in the fight against illicit drug use and its multiple harms, including the crisis of drug overdose deaths that has been affecting our country,” says Steven Pasik, PhD, VP, Scientific Affairs and Head of Clinical Data Programs. “It is of the utmost importance now to use all available data sources, including definitive urine drug tests, to track substance use trends, considering drug overdose deaths are at the highest level ever recorded. This information, including trends over time, plus geographic and demographic factors impacting use, can better influence interventions across the continuum of care.”
