The Justice Department will dispatch 12 federal prosecutors to cities ravaged by addiction who will focus exclusively on investigating health care fraud and opioid scams that are fueling the nation’s drug abuse epidemic, Attorney General Jeff Sessions said Wednesday.

He unveiled the pilot program during a speech in hard-hit Ohio, where eight people a day die of accidental overdoses.

“In recent years some of the government officials in our country I think have mistakenly sent mixed messages about the harmfulness of drugs,” Sessions said. “So let me say: We cannot capitulate intellectually or morally unto this kind of rampant drug abuse. We must create a culture that’s hostile to drug abuse.”

Highland County has been hit hard by opioid-induced overdoses, including fatal overdoses. Local first responders have said the number of overdose calls are on a record pace, far outpacing last year’s rate.

Highland County Coroner Jeff Beery has reported that there has been a steady increase in deaths related to drugs, raising fatalities connected to illicit drugs to alarming proportions.

For 2016, Beery identified 16 drug overdose deaths in Highland County. But he provided a report on 50 cases from 2016 that included not just overdoses, but also deaths by car crashes, burns, gun shots, heart attacks, hyperthermia, suicides, asphyxia and embolisms where he said drug use or a history of drug use were present as common denominators.

Meanwhile, the Highland County Health Department has begun providing free naloxone kits for people to use to attempt to revive overdose victims.

The Highland County Drug Abuse Prevention Coalition has been meeting regularly to craft a plan to reduce drug abuse, implement treatment strategies and organize community-wide advocacy efforts. The group, comprised of local public health officials, treatment professionals, law enforcement officers and faith-based representatives, meets monthly to exchange ideas and share resources in the fight against drug abuse.

Sessions said Wednesday in Columbus that the group of prosecutors he has dubbed the “opioid fraud and abuse detection unit” will rely on data in their efforts to root out pill mills and track down doctors and other health care providers who illegally prescribe or distribute narcotics such as fentanyl and other powerful painkillers.

In May, Sessions instructed the nation’s federal prosecutors to bring the toughest charges possible against most crime suspects. Critics assailed the move as a return to failed drug-war policies that unduly affected minorities and filled prisons with nonviolent offenders.

The announcement was a reversal of Obama-era policies that is sure to send more people to prison and for much longer terms.

Advocates warned the shift would crowd federal prisons and strain Justice Department resources. Some involved in criminal justice during the drug war feared the human impact would look similar.

Prescription opioids, along with street heroin, are behind the deadliest drug overdose epidemic in U.S. history. More than 52,000 Americans died of overdoses in 2015 — a record — and experts believe the numbers have continued to rise. Sessions has made aggressive prosecutions of drug crime a top priority, saying the deadly overdoses necessitate a return to tougher tactics.

The Health Department says opioid-related overdoses killed 3,050 Ohioans in 2015, with that number expected to jump sharply for 2016.

In June, the coroner serving the greater Columbus area said overdose deaths through April of this year rose to 173, a 66 percent jump from a year ago.

“That’s 173 mothers, fathers, sons, daughters, sisters, brothers,” said Columbus Mayor Andrew Ginther, a Democrat who said state and federal help is needed to fight the epidemic.

The prosecutors will be based in U.S. attorney’s offices in the Middle District of Florida; the Eastern District of Michigan; the Northern District of Alabama; the Eastern District of Tennessee; Nevada; the Eastern District of Kentucky; Maryland; the Western District of Pennsylvania; the Southern District of Ohio; the Eastern District of California; the Middle District of North Carolina; and the Southern District of West Virginia.

Some Democrats criticized Sessions’ proposal, saying more treatment options are needed to fight the epidemic.

The budget proposals of President Donald Trump and congressional Republicans and efforts to repeal Obamacare, including the expansion of Medicaid, “would likely make the opioid epidemic worse,” said Mandy McClure, a spokeswoman for the Democratic National Committee.
