Prescription drug addiction will be the topic of the night at a presentation Thursday at the Hall County Schools office. The Drug Free Coalition of Hall County is putting on the event from 6-7 p.m. at the 711 Green St. office for any students and adults interested. P. Tennent Slack, who locally practices interventional pain medicine, will make a presentation about the scope of the prescription drug overdose crisis, including a look at why the problem arose and how to effectively address it.
