The positive drug test rate for the U.S. workforce was 4.2 percent in 2016, according to the Drug Testing Index (DTI) released by Quest Diagnostics. This represents a 5 percent increase over the positive rate in 2015, and the largest single-year positive rate since 2004.
The DTI analyzed over 10 million workforce drug test results from 2016 and categorized employees into three categories, including employees with federally mandated drug tests, the general workforce and the combined U.S. workforce. Here are additional details about the DTI’s findings for specific drug types:
Marijuana: The positive test rate for marijuana increased nearly 75 percent in oral fluid testing, which is used in the general workforce. Federally mandated marijuana tests only utilize urine tests, and the positive test rate increased 10 percent in 2016.
Cocaine: Positive test rates for cocaine in post-accident drug tests were more than twice as high as pre-employment screenings.
Amphetamines: Positive test rates for amphetamines have risen 64 percent between 2012 and 2016 for the general workforce. Quest Diagnostics attributes this increase to the prevalence of prescription drugs, including Adderall.
