WASHINGTON (AP) — Federal and state prosecutors have collected more than $30 billion from drug companies for alleged fraud and illegal marketing over the last 20 years, according to a new report by consumer advocacy group Public Citizen.

The report shows that state attorneys are increasingly following the lead of federal prosecutors in seeking multimillion-dollar settlements with drugmakers such as GlaxoSmithKline and Eli Lilly & Co. Analysis by Public Citizen found that state governments have collected $3.7 billion from drugmakers since 2009, or roughly six times more money than in the previous 18 years combined.
