More Wisconsin workers testing positive for coke, meth, pot

Workforce drug positivity is at the highest rate in a decade, including in Wisconsin, finds an analysis of more than 10 million drug test results. What can business leaders do about it?

Positive drug tests among workers nationally and in Wisconsin are at the highest rate in a decade, based on more than 10 million U.S. drug tests compiled and released by Quest Diagnostics, one of the largest medical labs in the country.

That should be concerning to business leaders, already struggling to fill their ranks during a worker shortage. However, that bombshell also comes with a caveat.

The rise in positive drug tests is driven by increases in cocaine, methamphetamine, and marijuana use by American workers. Nationally, the positivity rate for the combined U.S. workforce held steady at 4.2% in 2017, the same as in 2016, but a “dramatic increase” over the 3.5% positivity rate from 2012, which represented a 30-year low, a press release from Quest Diagnostics notes.

The findings were unveiled at the Federal Transit Administration (FTA) Drug and Alcohol Program National Conference in Ft. Lauderdale, Florida, in early May. Quest’s Drug Testing Index (DTI) has revealed insights into drug use in the U.S. since the Drug-Free Workplace Act was signed into law in 1988. That year, the DTI analysis found that the overall drug positivity rate among American workers was 13.6%.

There’s the caveat. While the rate of U.S. workers testing positive for drugs might be at a 10-year high, it’s still well below the mark established when testing began 30 years ago. We’re hardly seeing an epidemic.

However, it’s impossible to argue that more workers are testing positive for drugs in the past year, especially in Wisconsin.

Wisconsin workers tested positive for drugs at a rate of 4.8% in 2017, higher than the national rate. The rate in Madison ranged from 3.5%–4.5%, while the rate for the south-central region for Wisconsin ranged from 4.5%–5.5%.

Cocaine positivity in urine testing increased in Wisconsin by a substantial 13% from 2016 to 2017 and methamphetamine use increased 167% in the East North Central division of the Midwest, which includes Illinois, Indiana, Michigan, Ohio, and Wisconsin.

The Quest Diagnostics data also shows cocaine positivity increased by double digits in certain other states. Methamphetamine positivity skyrocketed in the Midwestern and Southern United States. Marijuana positivity rose considerably in states that recently enacted recreational use statutes.

Perhaps surprisingly, given the amount of attention and scrutiny given to the opioid crisis, the prescription opiate positivity rate dropped by double digits nationally.

“These changing patterns and geographical variations may challenge the ability of employers to anticipate the ‘drug of choice’ for their workforce or where to best focus their drug prevention efforts to ensure a safe and healthy work environment,” says Barry Sample, PhD, senior director, science and technology, Quest Diagnostics.

What can business leaders do?

“I can say that among some of my clients, there are concerns about how to navigate this new climate,” says Ashlie Johnson, HR consultant and owner of Brooke Human Resource Solutions in Madison. “My role is to help them determine the risks and rewards of making adjustments to policy, as there can be significant risks, as well as opportunities presented when you remove this barrier to employment.”

Companies in states that have legalized either recreational or medicinal marijuana are leading the way on dropping drug tests, for example. However, because Wisconsin has not yet legalized marijuana, the Badger State has not experienced an associated decline in testing.

By removing a pre-employment drug screen from their process, an employer opens up their field of potential candidates,” suggests Johnson. “Right now employers are struggling to hire workers in the tightening job market, and the idea of having a larger pool to choose from can be very attractive.”

Of course, the risks associated with removing drug screenings lies mostly in workers’ compensation and client damages costs, Johnson notes. The average cost of a workers’ comp claim rose more than 500% between 1991 and 2012, and has continued to climb since then.

It seems obvious, Johnson says, that employees under the influence of alcohol and drugs — including legally prescribed or recreationally permitted ones — are more likely to be hurt on the job, and the available data reflects that. According to the U.S. Department of Labor, substance-abusing employees are five times more likely to file a workers’ compensation claim than the average employee.

“However, it should be pointed out that there can be challenges to using tests to determine intoxication after an incident, too,” explains Johnson. “Marijuana can stay in the system for a prolonged period of time, and the presence of marijuana in a test does not mean that the employee was necessarily cognitively impaired at the time of the incident. States differ on their approaches to intoxication and workplace accidents. Some even call for proving an intoxicated worker caused their injury for their workers’ comp claim to be denied, which is problematic when a positive marijuana drug test is submitted as the only evidence.”
