There are an estimated 2,000 current lawsuits and federal charges filed by patients, hospitals, US states and federal prosecutors against pharmaceutical companies relating to the supply, distribution and marketing of opioid medications. The cases allege that those companies have contributed to recent rises in opioid painkiller use, addiction, overdose and related fatalities. Many cite cases where pharmaceutical companies have marketed and distributed opioid painkillers in ways that have been deceptive, illegal, or harmful or that knowingly allowed illegal distribution channels to thrive. Some lawsuits have been filed by hospitals attempting to recover costs from treating addiction and overdose. There are now 39 states that have filed lawsuits against Purdue Pharma LP, the makers of OxyContin, citing their role in the US opioid epidemic.
