Secaucus, NJ — Paced by a continuing increase in marijuana positivity rates, the positive drug test rate for U.S. workers reached its highest level in two decades in 2021, according to an annual analysis conducted by lab services provider Quest Diagnostics.

Researchers examined the results of more than 11 million samples taken last year for Quest Diagnotics’ Drug Testing Index from the combined U.S. workforce – both the general workforce and employees in safety-sensitive jobs who undergo federally mandated drug testing (e.g., pilots, truck drivers, train conductors and nuclear power workers). Overall, 4.6% of the samples tested positive – up from 4.4% in 2020 and the highest percentage observed since 2001, when it was also 4.6. That figure is more than 30% higher than the 30-year low of 3.5% recorded in 2010, 2011 and 2012.

For all workers, urine samples had a marijuana positivity rate of 3.9% last year – the highest ever recorded. That percentage is up 8.3% from 3.6 in 2020 and up 50% from 2.6 in 2016. Among the federally mandated, safety-sensitive workforce, urine samples had a marijuana positivity rate of 0.86% last year, up from 0.79% in 2020 – an 8.9% increase.

The industries with the highest overall positivity rate increases were transportation and warehousing (to 5.5% from 4.4%), other services (to 6.6% from 5.7%) and retail trade (to 7% from 6.2%). Mining (to 3.7% from 3.1%), construction (to 4.6% from 4.1%) and manufacturing (to 4.5% from 4.1%) all saw increases of at least 0.5 percentage points. Finance and insurance was the only industry not to show an annual increase, remaining at 3.3%.

Other key findings:

  • The overall positivity rate among the federally mandated, safety-sensitive workforce remained steady at 2.2% – but that’s up 4.8% since 2017.
  • For federally mandated, safety-sensitive workers, the positivity rates for amphetamines and cocaine increased 7.8% and 5%, respectively.
  • In the general workforce, positive urine tests for opiates fell 19%, and have fallen 56.4% over the past five years.
  • Post-incident positivity among the general workforce has increased 26% over the past five years. Post-incident urine tests for marijuana and cocaine were up 63.4% and 266.7%, respectively, compared with pre-employment testing.
