By Ben FelderFifty-seven percent of Americans believe pharmaceutical companies should be held responsible for making the opioid crisis worse, according to a new poll by NPR and Ipsos.The poll also found a third of Americans have been touched directly by the opioid epidemic."One in three have been personally affected in some way, either by knowing someone who has overdosed or by knowing someone with an opioid addiction," said Mallory Newall, lead Ipsos researcher on the survey.Dozens of states, including Oklahoma, have filed lawsuits against drug companies, accusing them of causing the opioid epidemic by making fraudulent marketing claims that greatly understated the addictive risks of opioid painkillers while overstating the treatment benefits.Oklahoma filed a lawsuit against multiple drug companies in 2017 and a trial is scheduled to begin on May 28.
