The rate of urine drug testing positivity in the U.S. workforce climbed 4.5 percent in 2019 to a 16 year high (no pun intended) according to an analysis by Quest Diagnostics. Marijuana positivity in the U.S. workforce increased nearly 11 percent from 2018 to 2019 and 29 percent since 2015 and a whopping 28% percent higher than the thirty-year low of 3.5 percent recorded between 2010 and 2012.
