Residents in Westchester and Hudson Valley took part in National Drug Take Back Day Saturday.

Officials say that people disposed of unused, unwanted or expired pills at various sites throughout the region.

It is part of an effort to combat opioid addiction by taking drugs out of circulation.

"The risk is that while they are there, young people or even adults can get a hold of opioid medications that are sitting around and use them improperly," said Robert van Cura, undersheriff of Rockland County.

On the last National Prescription Drug Take Back Day, held back in October, officials say more than 42,000 pounds of medication were collected across New York state.

Representatives from the sheriff's office say that people can dispose of unwanted medications anytime at their office and some police departments in the county.
