Workforce drug testing shows downward trend in overall use

Marijuana 3

Overall drug use in the workplace continues to drop, according to Diagnostic Laboratory Services.

The company said Tuesday that amphetamine use has dropped 33 percent since the end of 2012, marijuana use is down 26 percent and the use of synthetic urine dropped 56 percent.

“We are seeing an overall downward trend in the use of amphetamines (speed, methamphetamine), marijuana and synthetic urine, which can mask marijuana in our workforce drug testing,” said Carl Linden, scientific director of toxicology at Diagnostic Laboratory Services.

However, the use of cocaine rose slightly from 0.2 to 0.3 percent from last quarter, and, even though DLS reports a significant downward trend in overall synthetic urine use, numbers had a slight uptick from 0.3 to 0.4 percent last quarter.

In 2012, Hawaii banned several categories of legal synthetic drugs, such as bath salts, but they cannot be tested for in workplace drug testing according to federal and state law, unless ordered by a physician.
