KINGSPORT — As drug overdose deaths continue to rise in Tennessee, local groups have joined together to take a public stand against drug use. Johnnie Mae Swagerty, executive director of South Central Kingsport Community Development and New Vision Youth, is inviting local residents to a walk designed to raise awareness about the drug problem in the region. “We just want to get the message out to the community, especially our young people,” Swagerty said.
