A comprehensive new study has found that stress and anxiety are key drivers in the U.S. overdose crisis, with poor mental health increasing the risk of dying from a drug overdose by as much as 39 percent.

"We saw a strong association with mental health and substance abuse disorders, particularly opiates," says co-author Diego Cuadros, PhD, an epidemiologist who directs the University of Cincinnati’s Health Geography and Disease Modeling Laboratory. "What's happening now is we're more than a year into a pandemic. Mental health has deteriorated for the entire population, which means we'll see a surge in opiate overdoses."

Cuadros and his colleagues looked at overdose deaths and socioeconomic data in the U.S. from 2005 to 2017, and identified 25 “hot spots” or sub-epidemics where there was a sizeable increase in drug deaths. In the Southwest, sub-epidemics were driven by methamphetamine and heroin, while overdoses in the Northeast and Midwest were first fueled by heroin, then prescription opioids, and now synthetic opioids such as illicit fentanyl.

U.S. Overdose “Hot Spots”

While different substances were often involved in sub-epidemics, researchers say the one thing they all had in common was high levels of physical and mental distress.

"This is a complex epidemic. For HIV we have one virus or agent. Same with malaria. Same with COVID-19. It's a virus," Cuadros said. "But with opioids, we have several agents. At the beginning of the epidemic it was heroin. By 2010 it switched to prescription opiates."

Deaths of Despair

The study, published in PLOS ONE, builds on the so-called “deaths of despair” theory that was first described in 2015 by Princeton researchers Anne Case and Angus Deaton, who found that the reduced life expectancy of middle-aged white Americans was linked to substance abuse, unemployment, limited education, divorce, depression and loss of social connections.

The new study found that young white males aged 25 to 29 were most at risk of a fatal opioid overdose, followed by white males aged 30 to 34. In recent years, they were joined by black males aged 30 to 34 who also have an elevated risk of dying from an overdose. Those age groups do not fit the typical profile of a pain patient on prescription opioids, who is usually older and has an age-related disability such as arthritis.

“For the past 20 years, seniors over age 62 have had the highest rates of doctor-prescribed opioid pain relievers, while sustaining the lowest and mostly stable rates of opioid overdose related mortality. During the same period, overdose mortality more than tripled among adults age 25 to 34, who receive far fewer prescriptions than seniors,” says Richard “Red” Lawhern, PhD, a patient advocate who has long argued that the demographics of the overdose crisis prove it is not being driven by opioid medication. 

“Drug abuse and addiction are instead driven by complex socio-economic factors that some investigators have called ‘a crisis of hopelessness.’ Structural unemployment and poverty have rendered some populations more vulnerable to drug abuse than others,” said Lawhern.

“Hot spots of high mortality occur primarily in rural counties of the Rust Belt, deep South and West, with a sprinkling in inner cities also paralyzed by poverty. Communities are being hollowed out and families are failing due to a national failure to invest to replace infrastructure and mining jobs formerly held by high school educated men.”   

A notable holdout in the “deaths of despair” theory is Andrew Kolodny, MD, an addiction treatment specialist and longtime critic of opioid prescribing who is the founder of the newly renamed Health Professionals for Responsible Opioid Prescribing (PROP).

“The vast majority of drug overdose deaths are occurring in people with the disease of opioid addiction, not necessarily people who are drinking or using drugs driven by socioeconomic factors,” said Kolodny in a recent webinar. “The deaths of despair framing, while provocative, is unlikely to explain the main sources of the fatal drug epidemic and that efforts to improve economic conditions in distressed locations, while desirable for other reasons, are not likely to yield significant reductions in drug mortality.”

Kolodny is not an economist, epidemiologist or pain management specialist. He is a well-paid expert witness in opioid litigation cases – lawsuits that depend on a public narrative that excess opioid prescribing, not mental health problems, led to the addiction and overdose crisis. Maintaining that narrative is becoming harder, with opioid prescribing in the U.S. at 20-year lows and overdose deaths at record highs, fueled in part by economic and social issues exacerbated by the pandemic.

In other comments during the webinar, Kolodny said the CDC’s 2016 opioid guideline was “a bit wishy washy” because it only said that opioids were not the preferred treatment for chronic pain. Kolodny said a Department of Veterans Affairs and Department of Defense guideline that came out a year later was “a lot better” because it advised doctors not to begin long-term opioid therapy on any new patients.    

Instead of opioids, the DOD guideline recommends exercise, yoga and cognitive behavioral therapy to treat chronic pain, along with non-opioid drugs such as gabapentin.
