Oklahoma has argued that the drugmaker's marketing of painkillers contributed to thousands of overdose deaths and other harms in the state and is asking for a multibillion-dollar award.

Oklahoma's trial is the first in a wave of litigation attempting to bring claims against opioid manufacturers. The state is seeking millions of dollars in damages and penalties.

Lawsuits over the way drugmakers have marketed opioids are already putting a dent in companies' reputations. Litigation has forced the release of internal documents that are shifting the narrative.
