Drug Positive Rates In Combined US Workforce, 2013 and Trends

"Methamphetamine Positivity Increases Across All Testing Types
"Amphetamines are a class of central nervous system stimulants that includes methamphetamine (best known for being produced in clandestine labs) and prescription medications for conditions such as ADHD and narcolepsy.
"Continuing a multi-year upward trend, amphetamines use – specifically the use of methamphetamine – showed an increase across all three specimen types. Combined U.S. workforce data in urine showed a 10 percent (0.85% vs. 0.77%) year-over-year increase in amphetamines positivity in 2013 compared to 2012. In the U.S. general workforce, methamphetamine positivity in urine drug tests increased 27 percent (0.14% vs. 0.11%); oral fluid methamphetamine positivity increased by 50 percent (0.24% vs. 0.16%). In addition, the positivity rate in hair testing jumped by 55 percent (1.2% vs. 0.77%). Amphetamines positivity rates are now at their highest levels on record and methamphetamine positivity rates are at their highest levels since 2007, across all specimen types.
"Oxycodones Positivity Declines for the Second Consecutive Year
"The DTI data also reported declines for prescription opiates positivity in urine drug tests. Prescription opiates refer to drugs used for pain management, such as hydrocodone and oxycodones. The current data shows oxycodones positivity declined 8.3 percent (0.88% vs. 0.96%) between 2013 and 2012 and 12.7 percent (0.96% vs. 1.1%) between 2012 and 2011 in the combined U.S. workforce. Four states experienced double-digit declines in oxycodones positivity rates in both 2013 and 2012: Florida, Massachusetts, New Jersey and Ohio. Hydrocodone positivity remained at 1.3 percent between 2012 and 2013."
