MEDINA -- Three police departments, Medina, Medina Township and Montville Township now have a new weapon in their arsenal to battle the heroin epidemic.

They'll now carry the drug Narcan, a brand name for naloxone, in their cruisers to treat someone having a heroin overdose.

Narcan is an inhaled medication that can reverse a heroin overdose within seconds, putting the patient into immediate withdrawal.

Lorain police were the first in the state to carry the drug in their cruisers as part of a pilot program and saved 25 lives within the first six months.

Earlier this month, Gov. John Kasich signed a bill into law that allows first responders and families of addicts to have access to Narcan.

Project DAWN, started last month, has been providing the drug to heroin addicts free of charge.

The Medina-area police departments are the first to be trained since the law passed.

The project is a collaboration between Cleveland Clinic's Medina Hospital and Summa Health Center at Lake Medina, who will provide the drug and replacements to the officers.
