LANSING, Mich. (AP) — Michigan State Police posts across the state are serving as collection points for expired, unwanted or unused prescription drugs.

Authorities say it is part of an effort to curb prescription drug abuse.

Medications may be dropped off Monday through Friday from 8 a.m. until 4 p.m., excluding holidays. No appointment is needed.

Liquids, inhalers, patches or syringes are not accepted.

State police say support from the Livingston County Community Alliance and its “Red Barrel” program allowed all 29 posts to become drop-off sites.

Meanwhile, an annual household medication disposal event takes place on Tuesday at the state Capitol. And Saturday is the Drug Enforcement Administration’s National Prescription Drug Take-Back Day, where many agencies and organizations will accept unwanted drugs.
