Saturday's drug take-back event will feature three locations, one of them Walmart, and drive-through service.
The take-back, a U.S. Drug Enforcement Administration project that gets unwanted and expired medications out of medicine cabinets and out of temptation and puts them in the hands of police.
Each of Saturday's events will run from 10 a.m. to 2 p.m.
Conewango Township Police will collect at Walmart with co-sponsor Warren County Housing Authority.
Youngsville Borough Police will collect at its Railroad Street station. "We will assist elderly persons and those with handicaps so they don't have to get out of their cars," Chief Todd Mineweaser said.
City of Warren Police will set up a drive-through in the rear parking lot of the Third Avenue municipal building.
Warren Police Sgt. Brandon Deppen will also hold a take-back from 9 a.m. to 1 p.m. Friday at the Allegheny Community Center during Senior Expo.
Youngsville Police - by appointment - and Warren Police - during business hours - accept year-round drop-offs at their stations.
The Warren County Sheriff's Office is not hosting a take-back location.
"If anyone needs anything picked up, just call us, we'll pick it up," Sheriff Ken Klakamp said.
