If you have old or unwanted prescription medications, over-the-counter medicines or used mercury thermometers, you can safely dispose of them this Saturday from 10 a.m.-2 p.m. at two Knoxville Walgreens stores.

Members of the Knoxville Medication Collection Program will be on hand during those hours on Saturday, March 24, at the Walgreens located at 7400 Chapman Highway and the Walgreens located at 5320 Clinton Highway. They will collect and properly dispose of the unwanted medicines and thermometers. The empty plastic containers for the medicines will be recycled if left with the event organizers. A free digital thermometer will be given in exchange for every mercury thermometer turned in while supplies last.

The event is sponsored by the Knoxville Police Department, City and County Solid Waste Offices, the Tennessee Department of Environment and Conservation, UT Academy of Student Pharmacists, Hallsdale-Powell Utility District, the Metropolitan Drug Commission, United Healthcare, KUB, WBIR, Walgreens and the Knox County Health Department.

At all other times, unwanted medicines can be brought for safe disposal to the Knoxville Police Department Safety Building at 800 Howard Baker Jr. Ave.
