Drug Use By Workers, Job Applicants At Highest Rate In More Than A Decade

One of the largest medical labs in the country says drug use by workers and job applicants remains at its highest rate in more than a decade.

Quest Diagnostics Incorporated — a clinical laboratory that specializes in diagnostics — found between 2016 and 2017, cocaine, methamphetamine and marijuana made up the bulk of what people tested positive for in more than 10 million workplace drug tests; 100,000 of which were from Wisconsin.

According to nationwide data Quest Diagnostics released Tuesday, positive test results for cocaine went up 13 percent from 2016 to 2017. Marijuana continued to edge upward, and positive test results for meth went up 167 percent in Wisconsin, Illinois, Indiana, Michigan and Ohio.
