Doing some spring cleaning? Don’t forget the medicine cabinet.

The Michigan State Police is once again taking part in a national initiative that encourages residents to properly dispose of expired, unused and unwanted prescription pills.

All of MSP’s 31 posts will participate in National Prescription Drug Take Back Day from 10 a.m. to 2 p.m. Saturday.

That includes the MSP Gladstone post, 922 Lake Shore Drive in Gladstone.

This is one of two annual events held in partnership with the Drug Enforcement Administration and other police agencies, MSP advises in a news release. Nearly 650 pounds of pills were collected during the last Drug Take Back Day in October.

“By taking a few minutes to clear out expired or unused pills, you are proactively helping to prevent prescription drug misuse and abuse as well as protect the environment,” said Col. James F. Grady II, director of the MSP. “Drug Take Back Day allows for an accessible, anonymous, secure and easy way to partner with police to help keep Michigan communities safe.”

Unused or expired prescription medications are a public-safety issue, leading to accidental poisoning, overdose and abuse, according to the DEA.

Pharmaceutical drugs are just as dangerous as street drugs when taken without a prescription or a doctor’s supervision, the DEA advised, adding that the majority of those abusing prescription drugs get them from family and friends, or the home medicine cabinet.

Unused prescription drugs thrown in the trash can be retrieved and abused, or illegally sold. They also can contaminate groundwater or soil. Unused drugs that are flushed can contaminate the water supply. Proper disposal of unused drugs saves lives and protects the environment, according to the DEA and the Michigan Department of Environment, Great Lakes and Energy, or EGLE.

All collected pills will be destroyed; no questions asked. Liquids, inhalers, patches and syringes will not be accepted. The DEA also advises no vitamins/supplements, vapes or recreational marijuana products.

Anyone unable to participate in National Prescription Drug Take Back Day can anonymously surrender prescription drugs at any MSP post from 8 a.m. to 4 p.m. Monday through Friday, excluding holidays.
