OPPGetting rid of unused or expired prescription medications in a safe manner.  That’s the purpose behind Prescription Drug Drop Off Day in Wawa, where those medications can be dropped off at 34 Pinewood Drive in Wawa on Saturday.  Officers with the Superior East OPP Wawa detachment will be collecting prescriptions there that have expired or are going unused from 10 until 3 o’clock.  OPP officers representing more than 70 detachments collected 138 kilograms of prescription medications last year.
