An environmental group says, a Drop-Off Program in Northern Michigan is helping prevent drugs from contaminating the region's waterways.
The "Tip of the Mitt" Watershed Council in Petoskey says, the program began three years ago; people can dispose of unwanted prescriptions, over-the-counter medications, and personal care products at certain law enforcement agencies.
Almost 5,000 pounds have already been collected.
For many years, people were advised to flush unused drugs down the drain to avoid misuse.
But, scientists determined that pharmaceuticals were polluting waterways and called for other means of disposal.
"Tip of the Mitt" policy specialist, Jennifer McKay says, the network of drop boxes gives people a safe alternative.
The boxes can be found at police agencies in Antrim, Charlevoix, Cheboygan, Emmet, and Grand Traverse Counties.
