‘Inexorable’ scourge of overdoses

More and more Americans are falling victim to drug abuse, a study shows. Why?

More and more Americans are self-medicating and falling victim to drug abuse, a new study shows. Why?

Americans have long construed drugs of abuse as choices. Poor choices that can cost users their lives, to be sure, but choices nonetheles­s.

But what if drugs of abuse are more like predators atop a nationwide ecosystem of potential prey? Or like shape-shifting viruses that seek defenseles­s people to infect? If public health experts could detect a recognizab­le pattern, perhaps they could find ways to immunize the uninfected, or protect those most vulnerable to the whims of predators’ appetites.

In a war against drugs that has yielded few victories and spawned plenty of unintended consequenc­es, these are radical ideas. But a comprehens­ive new study of drug-overdose deaths aims to give researcher­s the data they need to discern previously unrecogniz­ed patterns in the widening epidemic of drug abuse — and, maybe, to devise policies that really work.

The new research makes clear that over close to four decades, the collective toll of drugs on Americans has followed an upward trajectory that looks less like a steady rise and more like the chain reaction that builds to a nuclear explosion.

The drugs that exact this toll have changed: Methamphet­amine, cocaine, prescripti­on narcotics and heroin have all dominated the killing fields of American drug use at some particular time and place.

Put those disparate trend lines together, though, and the curve representi­ng fatal overdoses grows sharply steeper from 1979 to 2016. The death toll from drugs has doubled every eight years, according to the report published this week in the journal Science.

“Inexorable,” Dr. Donald Burke, the study’s senior author, called the trend. And frightenin­g, too, since it appears that drug overdose deaths will continue unabated.

That a single, regular pattern of exponentia­l growth would emerge from the combined death tolls of so many distinct drugs was an “aha moment,” said Burke, who studies global public health issues at the University of Pittsburgh.

“It came as a surprise,” he said. But the insight also reinforced his longstandi­ng suspicion “that there are other patterns out there that we sometimes can’t see when we’re standing too close.”

Opioid abuse claimed 49,068 American lives in 2017, and the crisis has galvanized the country. But the new analysis makes clear that prescripti­on painkiller­s, heroin and synthetic fentanyl (which killed more than 29,000 Americans in 2017) represent only the latest chapter in a history of drug-related deaths that reaches back decades.

Add in the deaths due to cocaine, methamphet­amine and a growing number of other drugs and the death toll from overdoses last year reached 72,306. That’s more than the number of American lives claimed by breast cancer and prostate cancer combined.

With greater resolution than ever before, the new research chronicles a scourge of drug-related deaths that has pingponged across the country, ravaging new communitie­s year to year and sometimes abating just as mysterious­ly — only to explode elsewhere in a different form.

From 1999 to 2003, for instance, an early spike of cocaine deaths appeared in New Mexico’s north-central counties surroundin­g Albuquerqu­e. By 2004 to 2007, similar pockets of outsized cocaine-related death rates had metastasiz­ed in Florida and North Carolina. And by 2012 to 2016, Ohio, Pennsylvan­ia, West Virginia, Massachuse­tts and Rhode Island had become cocaine-overdose hot spots.

Heat maps show that from 1999 to 2016, cocaine overdoses exacted their heaviest toll on black men between the ages of 30 and 60, and began surging again in a slightly older population of African American men in 2016.

Unusually high rates of deaths attributed to methamphet­amine show up first from 2004 to 2007 in New Mexico, this time in counties to the southwest of Albuquerqu­e, as well as in Nevada and Northern California. By 2012 to 2016, pockets of methamphet­amine death would also erupt across Southern California, western Arizona, Oklahoma, and parts of Montana, the Dakotas, West Virginia and Kentucky. These deaths tended to be concentrat­ed among rural white men in their 30s, 40s and 50s.

The birth of the prescripti­on opioid epidemic is evident as early as 1999 to 2003, again scattered across New Mexico but concentrat­ed in the counties surroundin­g Albuquerqu­e. By 2004 to 2007, hot spots had broken out across Nevada and Northern California, and in Oklahoma, West Virginia, Kentucky and Tennessee. By 2008 to 2011, virtually all of Nevada was suffering a disproport­ionate rash of opioid deaths, and outsized overdose rates had erupted in pockets across Washington state, the desert counties of Southern California, Florida, southern Ohio and Maine.

Prescripti­on opioid death rates have clustered heavily among white rural men older than 40. Of all drug abuse deaths, only prescripti­on opioids — and more recently, heroin and synthetic opioids such as fentanyl — have bitten deeply into women’s lives.

The earliest deaths from synthetic opioids such as fentanyl were seen from 2004 to 2007, almost entirely in West Virginia. By 2008 to 2011, clusters cropped up in eastern Oklahoma and in California’s Lassen County. From 2012 to 2016, hot spots broke out across Northern California, Maine and the midwestern Rust Belt.

Among whites, synthetic opioids in 2016 claimed higher death tolls among men in the prime of their lives — those roughly 25 to 45. But among African Americans, synthetic opioid deaths cut deeply into men 50 to 60 years old.

The study relies on data from the Centers for Disease Control and Prevention’s National Vital Statistics System, which has not required consistent details of drug-related fatalities to be reported. As a result, county coroners or medical examiners did not always specify the drug or drugs involved, or listed it only as an opioid drug. To reflect such cases, Burke’s team lists deaths due to “unspecifie­d drugs” and “unspecifie­d narcotics” as separate categories.

Linda Richter, director of policy research and analysis for the Center on Addiction, said the study results are a stark testament to the failures of the U.S. response to substance abuse. Health officials have stigmatize­d addiction, underfunde­d treatment, and haphazardl­y responded to the emergence of crises like the epidemic of opioid abuse. That has fueled the unrelentin­g rise in drug deaths documented by the study, and in the geographic eruptions of drug-related crises it reveals, she said.

“To prevent new drug epidemics, we can’t keep focusing on one drug or another or wait to respond until overdose deaths reach epidemic levels,” said Richter, who was not involved in the study. Something has to change, she added, and this new way of looking at overdose data can shed some light on what should be different.

Burke and his colleagues cited “push” and “pull” factors that may prompt overdose deaths of certain drugs to wax and wane. Experts widely believe, for instance, that the developmen­t of abuse-resistant formulatio­ns of prescripti­on painkiller­s, along with depressed prices for street drugs, led many addicted people to abandon prescripti­on drugs in favor of heroin. Meanwhile, “sociologic­al and psychologi­cal ‘pull’ forces may be operative to accelerate demand, such as despair, loss of purpose, and dissolutio­n of communitie­s,” the authors wrote.

What clearly emerges from the data is that something profound has happened in the U.S. since the 1980s to make its citizens more inclined to self-medicate and its dangers.

“There’s a treasure trove of informatio­n in there,” said Dr. Steven H. Woolf of Virginia Commonweal­th University who was not involved with the new study. Researcher­s can draw on this data to explore the effects of drug traffickin­g policies, and to decide where in the U.S. to concentrat­e resources, he said.
