Indiana residents would be able to discard unneeded or expired prescription drugs at pharmacies under a bill that's been entered in the Indiana House.

A bill authored by Republican Rep. Kevin Mahan of Hartford City would revise state law so that pharmacies could accept unused prescription drugs from customers and dispose of them securely and safely.

State Attorney General Greg Zoeller voiced support for the bill during a news conference Monday. He said parents' medicine cabinets often are the source of prescription drugs misused by teenagers.

Pharmacies in some other states provide disposal bins where consumers can discard medicines, but state law would have to be changed to allow that in Indiana.

The bill has been assigned to the House Public Health Committee.
