Baltimore City and Anne Arundel, Baltimore, Cecil, Harford, and Montgomery counties claim the pharmaceutical industry expedited the epidemic by hiding or minimizing addiction risks yet aggressively marketed their products to the public and medical professionals. The counties are requesting financial relief for their costs of responding. As many as 200 U.S. cities and counties have filed or plan to file so far. The David v Goliath tactic is reminiscent of the 1990s when every state joined a suit against the tobacco industry. The $246 billion settlement against 13 corporations was reached after four years of maneuvering.
