Quest Diagnostics’ Drug Testing Index® Finds Cocaine Use At 10-Year Low Among U.S. Workers
Source: Quest Diagnostics Incorporated

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.
