Secaucus, NJ, May 8, 2018 – Driven by increases in cocaine, methamphetamine and marijuana, drug use by the American workforce remains at its highest rate in more than a decade, according to a new analysis released today by Quest Diagnostics, the world’s leading provider of diagnostic information services.

Nationally, the positivity rate for the combined U.S. workforce held steady at 4.2 percent in 2017, the same as in 2016, but a dramatic increase over the 3.5 percent positivity rate from 2012, which represented a thirty-year low. The analysis of 2017 data also suggests shifting patterns of drug use, with cocaine and amphetamines positivity surging in some areas of the country and marijuana positivity rising sharply in states with newer recreational use statutes. Prescription opiate positivity rates declined dramatically on a national basis.
