The Quest Diagnostics Drug Testing Index™ (DTI) measures positivity trends based on workplace drug test results. The findings are published as a public service for government, media and industry and are considered a benchmark for national trends.
The DTI report examines positivity rates – the proportion of positive results for each drug compared to all such drug tests performed among three major testing populations: federally-mandated, safety-sensitive workers; the general workforce; and the combined U.S. workforce.
In examining the most current data, Dr. Barry Sample, Director of Science and Technology at Quest Diagnostics, noted the following key findings:
- The percentage of positive drug tests among American workers has increased for the first time in more than a decade, fueled by a rise in marijuana and amphetamines positivity
- Marijuana positivity increased 6.2 percent nationally in urine drug tests, but by double digits in Colorado and Washington
- Detection of marijuana continues to increase significantly in oral fluid testing
- Methamphetamine positivity increased across all drug testing specimen types and is at its highest level since 2007
- Amphetamine continues its year-over-year increase in detection rates
- Oxycodone positivity declined for the second consecutive year
