The Hawaii County Police Department is encouraging the public to turn in unused, unneeded or expired prescription medications Oct. 29 in a nationwide prescription drug take-back program.

The prescription drug take-back program sponsored by the U.S. Drug Enforcement Administration, the state departments of the Attorney General and Public Safety, and community partners.

The following are Hawaii island collection sites for safe, anonymous disposal:

>> National Guard Aviation facility, 1095 Kekuanaoa St. (airport access road)

>> Hilo and Kealakehe police sation parking lot, 74-611 Hale Makai Place, Kailua-Kona.

Tablets, capsules and other solid forms will be accepted for incineration. No intravenous solutions, injectables and syringes will be accepted.

Illegal drugs such as marijuana will not be accepted.

Unused or expired medicine in the home poses a risk of drug abuse and accidental poisoning, police said. Proper disposal helps reduce the risk of entering the water supply or harming aquatic life.
