TETERBORO, N.J., Jun 28, 2002 /PRNewswire-FirstCall via COMTEX/ -- Workplace
drug use decreased after the events of September 11, 2001, according to the
semi-annual Drug Testing Index released today by Quest Diagnostics Incorporated
(NYSE: DGX), the leading employer of drug testing services in the United States.
The drug positivity rate for the combined U.S. workforce, which is the number of
positive test results compared to the total number of drug tests performed by
Quest Diagnostics for this category, dropped to 4.4% between September and
December 2001, compared to 4.7% during the same time a year earlier. For the
full year, the drug positivity rate for this category declined to 4.6% from 4.7%
in 2000. The post September 11th reduction drove the decline in positivity for
the full year, despite an upturn in on-the-job drug usage documented by the Drug
Testing Index among general U.S. workforce employees in the first half of the
year.
The Drug Testing Index examines drug positivity rates among three major testing
populations: federally-mandated, safety-sensitive workers; the general U.S.
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 positivity rate among the general U.S. workforce declined to 4.8% between
September and December 2001, from 5.0% during the same period a year earlier.
For the full year, drug positivity for this category remained at 4.9%, the same
rate seen in 2000. Among general U.S. workforce employees, the majority of drug
testing that Quest Diagnostics performs occurs prior to employment, as opposed
to while employees are on the job.
"While the drug positivity rate for the combined U.S. workforce declined in
2001, it is too soon to say whether a downward trend toward lower drug use will
continue," said Barry Sample, Ph.D., Director of Science and Technology for
Quest Diagnostics' Corporate Health and Wellness division. "The results for 2001
may be an aberration given the events of September 11th."
The positivity rate for federally-mandated safety-sensitive workers continued to
decrease to 2.7%, an all-time low, between September and December 2001, from
3.0% between September and December 2000. For the full year, drug positivity for
this category declined to 2.9% from 3.1% in 2000.
The Drug Testing Index is based on approximately 6.3 million tests performed
during 2001 by Quest Diagnostics.
