Prevalence and Types of Pre- and Post-Employment Drug Testing of Workers in the US
"Drug and alcohol screening tests remain a prominent part of the background check process, with 63% of responding organizations conducting this type of screening. That rate has remained relatively consistent over the last 10 years, except for an uptick in testing in 2012 and 2013 (78%)."
According to HireRight's 2018 survey, 51% of companies that responded said that they used an electronic Chain of Custody (eCOC) form; 42% said that they do not and had not plan to do so; and 7% said that they do not but plan to do so in the future.
Of the companies that test for alcohol or other drugs, 95% perform urine testing, 11% perform oral fluid (saliva) testing, 7% perform hair testing, and 3% use other tests.
