Amphetamines use in the workplace continues to grow
The use of amphetamines among general workforce employees continued to grow in 2004, according to the semi-annual Drug Testing Index® released last month by Quest Diagnostics Inc., a leading provider of employer drug testing services in the United States.
Amphetamines use, which grew rapidly between 2000 and 2003, continued to grow in 2004, although at a slower rate. Among general U.S. workforce employees, the incidence of positive drug tests attributed to amphetamines rose by approximately 6 percent in 2004 from 2003, reaching 0.52 percent of all drug tests that look for amphetamines among this group of workers. During 2003, amphetamines positivity was 0.49 percent. Between 2000 and 2003, year-over-year growth rates for amphetamines positivity had been 16 percent, 17 percent and 44 percent, respectively.
