Drug Test Positivity Rates for Methamphetamine Among US Workers Subjected to Drug Testing

"Amphetamines (which includes amphetamine and methamphetamine) positivity continued its year-over-year upward trend, increasing more than eight percent in urine testing in both the general U.S. and federally-mandated, safety-sensitive workforces compared to 2015. Throughout the last decade, this rise has been driven primarily by amphetamine use which includes certain prescription drugs such as Adderall®.
"Although methamphetamine positivity in urine testing declined between 2005 and 2008, the positivity rate plateaued between 2008 and 2012, and has increased steadily since. Between 2012 and 2016, it climbed 64 percent in the general U.S. workforce and 14 percent among federally-mandated, safety-sensitive workers. In oral fluid, methamphetamines positivity increased 75 percent between 2013 (0.24%) and 2016 (0.42%)."
