People were able to drop off old and unneeded prescription drugs at the 78th Precinct and four other precincts in Brooklyn Saturday with no questions asked and at no cost.

The initiative is part of National Drug Take back Day, a way for officials agencies to rid homes of unwanted prescription drugs.

It comes as the country faces an opioid epidemic. A 2015 survey showed 6.4 million Americans abused controlled prescription pills, including many that had been taken from friends and family.

By offering anonymous and free sites, the DEA aims to curb opioid addiction and overdoses by taking old and unwanted pills out of homes and medicine cabinets.

The DEA says unwanted or expired medications should not be just thrown out or flushed down the toilet. For people who missed Saturday's event, the DEA operates sites nationwide that can accept unwanted medications year-round.
