 Minnesota is suing the major pain killer producer of OxyContin alleging the pharmaceutical company misrepresented the medication and contributed to overdose deaths. Attorney General Lori Swanson filed a lawsuit against Purdue Pharma on Monday. She said Purdue touted faulty research saying OxyContin was not addictive and led to patient addiction and deaths. Minnesota Department of Health data shows deaths linked to opioid pain killers jumped from 54 in 2000 to 401 last year. A Purdue spokesman said Swanson's lawsuit would trigger a costly and protracted litigation process Swanson is running for governor as a Democrat this year.
