Double-digit declines reported across the U.S.LYNDHURST, N.J., Aug 09, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- An unprecedented decline
in cocaine use by American workers drove use of the illicit drug to a new low
during the first half of 2007, according to the "Quest Diagnostics Drug
Testing Index: Cocaine Use Among America's Workers -- A Special 2007 Mid-Year
Report." Released today by Quest Diagnostics Incorporated (NYSE: DGX), the
nation's leading provider of diagnostic and employment-related drug testing
services, the mid-year report describes positivity rates for cocaine only and
does not assess positivity rates for other drugs among U.S. workers. The
latest findings are based on results of more than 4.4 million workplace drug
tests for cocaine performed by Quest Diagnostics across the U.S. between
January and June 2007.

The 0.58 percent positivity rate for cocaine during the first six months
of 2007 in the combined U.S. workforce represents a 15.9 percent decrease from
the positivity rate for the full year 2006. Cocaine positivity in the first
six months of 2007 among the combined U.S. workforce is at its lowest point
since 1997, when the Quest Diagnostics Drug Testing Index first reported on
the positivity rate for cocaine as a percentage of all employer-related drug
tests performed to detect illicit drugs. The combined U.S. workforce refers to
general workers and federally mandated, safety-sensitive workers.
The Quest Diagnostics Drug Testing Index showed that positivity for
cocaine declined 20.7 percent among federally mandated, safety-sensitive
workers, to 0.46 percent for the first six months of 2007, compared to 0.58
percent for all of 2006. Among the general workforce, positivity for cocaine
declined 15.3 percent, falling to 0.61 percent for the period between January
and June 2007 compared to 0.72 percent for 2006.
"Not only did the positivity rate fall to its lowest level since Quest
Diagnostics began reporting on cocaine rates a decade ago, but also the
decline was truly across the board, falling by double-digits in all but one of
nine regions of the country," said Barry Sample, Ph.D., director of Science
and Technology for the Employer Solutions division of Quest Diagnostics.
"While it is too soon to point to a trend, the significant decline in
positivity rates in different workforce categories and across regions may
suggest that our nation's workers are choosing not to use cocaine or that they
lack access to the drug."
Regional Declines
The Quest Diagnostics Drug Testing Index also tracked cocaine positivity
rates for the combined U.S. workforce by nine geographic regional divisions of
the U.S., as defined by the U.S. Census Bureau and reported in the National
Survey of Drug Use and Health (NSDUH). The Northeast region's New England
Division, consisting of Connecticut, Maine, Massachusetts, New Hampshire,
Rhode Island and Vermont, experienced a decline of 21.9 percent, the largest
drop of all divisions, for the first six months of 2007 compared to 2006. The
Midwest Region's West North Central Division, which consists of the Dakotas,
Iowa, Kansas, Minnesota, Missouri and Nebraska, declined by 9.5%, the least
significant decline of the divisions.
"The Quest Diagnostics Drug Testing Index: Cocaine Use Among America's
Workers -- A Special 2007 Mid-Year Report" was developed partly at the
prompting of the White House Office of National Drug Control Policy.
"These data are encouraging," said John Walters, director of National Drug
Control Policy. "Cocaine has destroyed thousands of lives in the U.S. and
brought lawlessness and misery to our neighbors. But in recent years, we have
had unprecedented cooperation with leaders in Colombia and Mexico. Now is the
time to build on this progress."
About the Quest Diagnostics Drug Testing Index
The Quest Diagnostics Drug Testing Index is published as a public service
for government, media and industry, and has been considered a benchmark for
national trends since its inception in 1988. It examines positivity rates,
which represent the proportion of positive results for a drug 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. Federally mandated, safety-sensitive workers include pilots, bus
and truck drivers, and workers in nuclear power plants, for whom routine drug
testing is mandated by the U.S. Department of Transportation and the Nuclear
Regulatory Commission. The Drug Testing Index is released as a full-year and
mid-year report. The Quest Diagnostics Drug Testing Index: Cocaine Use Among
America's Workers -- A Special 2007 Mid-Year Report describes positivity rates
for cocaine only and does not assess positivity rates for other drugs among
U.S. workers.
