The Drug Enforcement Administration is holding a nationwide medicine collection event this month, and Walgreens stores throughout Central Illinois will be participating.
From the UnwantedMeds.org blog:
Communities across central Illinois will have an opportunity to safely dispose of unwanted medications this month. Another National Prescription Drug Take-Back Day will take place on Saturday, April 27 from 10 a.m. to 2 p.m. Local police departments will anonymously collect both prescription and over-the-counter medications — including pet medications. No sharps or syringes please.
The post linked above includes a list of local and area stores participating in the event. Additional information about the program can be found on the DEA’s website.
