Cocaine use in South Florida’s workforce has experienced a sharp decline this year compared to 2006, mirroring a national trend that shows the drug’s use at a 10-year low, a leading testing firm reports, says the Miami Herald. Nationwide, there was a 16 percent drop in positive workplace drug tests for cocaine in the first six months of the year, Quest Diagnostics said yesterday.
The Lyndhurst, N.J.,-based company compiled its report on 4.4 million drug tests conducted from January through June. The nationwide rate — about one test in every 172 was positive for cocaine — is the lowest in the 10 years since Quest began reporting cocaine in its testing index, a widely used benchmark. Those tested included people from the general work force as well as those with jobs that require federally mandated drug tests, like pilots, truck and bus drivers and nuclear power plant employees. White House drug czar John Walters partly credited drug-trafficking crackdowns in Colombia and Mexico, which together supply about 90 percent of the cocaine to the United States.
