On February 19, 2026, the Washington Supreme Court issued a unanimous ruling allowing families to pursue negligence claims against Amazon related to the suicides of four young individuals who ingested sodium nitrite, a toxic chemical available through the retailer's website. The court determined that lower courts had incorrectly dismissed the case, asserting that suicide does not automatically preclude liability under the state's product liability laws.
The consolidated lawsuits involve the estates of these victims—ages 17, 18, and 27—who died between 2020 and 2021 after ingesting sodium nitrite purchased online. Plaintiffs contend that Amazon's sales practices, which included inadequate warnings and product recommendations, contributed to the tragic outcomes.
Justice G. Helen Whitener emphasized that Amazon has a duty to exercise reasonable care to prevent foreseeable harm to its customers. The court criticized an earlier ruling that regarded suicide as a "superseding cause" that absolved Amazon of responsibility.
The families allege that Amazon sold high-purity sodium nitrite without implementing age verification or significant warnings about its lethality. Sodium nitrite is notably hazardous, where ingestion of merely 1-2 grams can be fatal. Furthermore, the plaintiffs claim Amazon recommended additional items—like scales and other chemicals—that could potentially assist in committing suicide when users viewed sodium nitrite listings.
Despite the ruling, Amazon stated it remains committed to customer safety, claiming that sodium nitrite is not intended for direct consumption and is generally used in food preservation. As of November 2025, the company implemented restrictions on selling sodium nitrite in concentrations higher than 10%.
The legal battle illustrates the growing scrutiny on online marketplaces, where families argue that companies like Amazon should be accountable for the products sold by third-party vendors, especially when they are aware of associated risks.
