National Drug Take-Back Day is this weekend and it's a day you can get rid of all your unused prescriptions. 

Residents in Hamilton, Bradley, Marion, and Polk counties can drive up and drop off their old medications on Saturday from 10:00 a.m. until 2:00 p.m. 

Event organizers say using a "take-back box" keeps medications from getting into the hands of children or in area waterways.

Almost all area police stations and sheriff's departments have a take-back box.
