From the Putnam Co OH Sheriffs Office Facebook page:
We encourage you to bring any unused prescription drugs to Ottawa Walmart on October 26th for DEA Prescription Drug Take Back Day. We will have Deputies set up outside of Wal-Mart from 10am-2pm, please give your unused prescription drugs to the deputies; DO NOT BRING THEM INSIDE. We also ask you not to bring liquids or needles. If you are unable to make it there, you may drop off any unused prescription drugs 24/7 at the Putnam County Sheriff’s Office.
