HONOLULU (HawaiiNewsNow) -- More Hawaii workers tested positive for amphetamine use in the third quarter of the year, according to figures from Hawaii-based Diagnostic Laboratory Services.
The lab said that .8 percent of workers tested positive for amphetamine use, up 14 percent from the third quarter of 2015.
Meanwhile, marijuana use dropped in the third quarter compared to earlier this year, but is still way up from last year.
Opiate use also dropped among workers tested, while the use of synthetic urine continues to increase.
The company's quarterly sample size is typically 7,000 to 10,000 workers.
