Drug Misuse in America 2019

Drug Misuse in America 2019: Physician Perspectives and Diagnostic Insights on the Evolving Drug Crisis, a Quest Diagnostics Health Trends™ report, presents findings from analysis of more than 4.4 million deidentified aggregated clinical drug monitoring tests performed by Quest Diagnostics for patients from all 50 states and District of Columbia from 2011 through 2018.
