(AP) — A corner of West Virginia wrenched by opioid addiction is getting the chance to argue in a courtroom that some of the corporate giants it blames for a public health crisis that left hundreds of people dead deserve to be held accountable.

The city of Huntington and surrounding Cabell County sued the nation’s three largest opioid distributors No matter the outcome of the federal court trial that opened this month, the verdict is expected to resonate well beyond the industrial region.

The trial in West Virginia, as well as legal proceedings underway in California, could set the stage for resolutions to similar lawsuits brought by thousands of local governments across the United States. Opioid overdoses have been linked to the deaths of nearly 500,000 Americans since 2000 and reached a record of nearly 50,000 in 2019.

Yet the sprawling nature of litigation over the addiction epidemic around the country means it could take years to wrap up, years to get money to communities to expand treatment and to make up for some of the economic losses caused by the crisis.

The trajectory of the lawsuits is unlikely to mirror the one of the lawsuits that states brought against the tobacco industry during the 1990s. The landmark litigation over what cigarette companies knew about the health risks of smoking resulted in a few sweeping settlements that distributed money to nearly every state, while the opioid cases involve a variety of plaintiffs suing companies up and down the pharmaceutical chain in state and federal courts.

Instead, the lawsuits arising from the use of powerful prescription painkillers could evolve more like the litigation over the cancer risk linked to asbestos, which also involved many corporate players and ended up stretching on for decades.

The Huntington and Cabell County case could lead the distributors that filled orders for OxyContin, generic oxycodone pills and other painkillers to agree to settlements elsewhere in the U.S. Other lawsuits target opioid manufacturers, pharmacies, and even the marketing and consulting firms that helped drugmakers promote the addictive medications.

University of Georgia law professor Elizabeth Burch expects many companies named in the various lawsuits will have to pay up eventually, regardless of the results of individual trials. But rulings for the plaintiffs could speed things up, she said.

“A win really helps the plaintiffs and creates momentum,” Burch said.

State attorneys general, local governments and other entities have filed thousands of lawsuits over the last five years aimed at making segments of the drug industry pay for the lives lost or derailed by addiction. Before April, only one opioid case brought by a government had reached trial; in 2019, on Oklahoma judge ordered Johnson & Johnson to pay the state $465 million. The company is appealing.

Other cases were settled before reaching trial.

For activists, settlements do not equal accountability. They want payments for victims or their families and a detailed accounting of what companies did to spark the crisis. Some also want to see individual company officials charged with crimes.

“You can murder one person and go to jail for life. You murder hundreds of thousands? You just put up some money and you don’t go to jail,” said Cynthia Munger, a Wayne, Pennsylvania, resident whose son is in recovery from opioid addiction. “Where’s the justice in that?”

Most of the pending civil lawsuits focused on drugmakers and distribution companies, but some also target pharmacy chains and more peripheral players.

This year, the consulting firm McKinsey & Company settled with most states for nearly $600 million for its role in advising OxyContin maker Purdue Pharma and others on selling opioids. Massachusetts sued the marketing firm Publicis Health earlier this month, accusing it of designing deceptive marketing schemes to help Purdue sell more OxyContin.

Two major opioid manufacturers — Purdue Pharma and the generic drugmaker Mallinckrodt — are using bankruptcy court to pursue universal settlements. In the Purdue case, state attorneys general are split over whether the proposed deal is sufficient to hold responsible members of the wealthy Sackler family who own the company. Under the proposal, they would give up Purdue Pharma and pay nearly $4.3 billion in cash.

Close to 3,000 lawsuits filed in federal courts have been consolidated under the supervision of U.S. District Court Judge Dan Polster of the Northern District of Ohio. Polster has scheduled a trial for later this year in Cleveland over claims against pharmacy chains. He also pushed for broad settlements while agreeing to hold federal trials across the country.

The West Virginia case against the national distribution companies – — AmerisourceBergen, Cardinal Health and McKesson – is the first of those cases to go to trial. From 2015 to 2020, more than 700 people died of opioid overdoses in Cabell County, which has a population of under 100,000.

An expert witness for the county and Huntington city used data compiled by the federal government to show that pharmaceutical distributors shipped nearly 128 million doses of prescription opioids to the county from 2006 to 2014 — or more than 140 per resident a year.
