KINGSPORT — District attorneys in Northeast Tennessee have filed lawsuits against opioid manufacturers. President Donald Trump has called abuse of the drugs an epidemic, meriting its designation as a nationwide public health emergency. And to further discussion and awareness of the crisis on the local level, the United Way of Greater Kingsport is encouraging teachers, parents, caregivers and city officials to attend a community forum on Monday night. The free event will be held at Sullivan South High School on Moreland Drive from 6-8 p.m.
