Attorneys general in Florida and Texas filed new lawsuits Tuesday against manufacturers and distributors of opioid drugs, alleging they intentionally misled people about the dangers of addiction.

The Florida lawsuit alleges, among other things, that opioid manufacturers used front organizations and key opinion leaders to promote false messages about opioids. These sources appeared to be neutral advocates for the use of opioids to treat chronic pain but were actually paid mouthpieces of the manufacturers, according to a statement from Attorney General Pam Bondi.
