- Opioid abuse and the decline in labor force participation are related, Fed Chair Janet Yellen says.
- "I don't know if it's causal or symptomatic of long-running economic maladies," she says.
- Goldman Sachs said last week opioid abuse is partly why more people aren't seeking work.
In her testimony before the Senate Banking Committee on Thursday, Yellen said rampant opioid abuse in the U.S. is related to the decline in labor force participation among prime-age workers.
"I don't know if it's causal or symptomatic of long-running economic maladies that have affected these communities and particularly affected workers who have seen their job opportunities decline," Yellen said in response to questioning from Sen. Joe Donnelly, D-Ind., on the issue.
The United States is "the only advanced nation that I know of where in these communities we're actually, especially among less-educated men, seeing an increase in death rates partly reflecting opioid use," she added.

Opioid overdose contributed to more than 33,000 deaths in 2015, according to the Centers for Disease Control and Prevention, and kills more than 90 Americans every day.
The U.S. Bureau of Labor Statistics reports the labor force participation rate has fallen since the Great Recession and has stagnated near 63 percent for the last four years.
Last week, a Goldman Sachs economist suggested opioid addiction is part of the reason more people aren't actively looking for work. "The opioid epidemic is intertwined with the story of declining prime-age participation, especially for men, and this reinforces our doubts about a rebound in the participation rate," David Mericle said.
Mericle added the economic consequences of opioid addiction extend beyond the labor market, including sizeable costs of health care and criminal justice.
On Wednesday, Yellen, speaking with the House Financial Services Committee, suggested that advancements in technology and globalization could eliminate the middle class.
