It’s part of the National Take-Back Initiative, which is aimed at preventing prescription drug abuse. It also helps prevent accidental ingestion and the contamination of water supplies.
“The Arlington County Police Department, Arlington County Sheriff’s Office and the Drug Enforcement Administration (DEA) will give the public another opportunity to prevent pill abuse and theft by ridding their homes of potentially dangerous expired, unused, and unwanted prescription drugs,” ACPD said in a press release. “Bring your medications for disposal to the designated collection sites. The service is free and anonymous, no questions asked.”
