A Hawaii drug testing company says crystal meth use has dropped to its lowest level since it began tracking workforce test statistics in 2004.

Diagnostic Laboratory Services said in a news release Thursday that for the second quarter of the year crystal meth use dropped from 1.1 percent to .4 percent among the workers and job candidates it tests.

Use of synthetic urine in an attempt to mask drug use was essentially the same as last quarter.

Marijuana, cocaine and opiate use also remained essentially the same.

Carl Linden is Diagnostic Laboratory Services’ scientific director of toxicology. He says the past quarter’s workforce drug testing statistics show relatively low drug use across the board. 

He says the drop in crystal meth is a welcome change from increases in previous years.
