The Michigan State Police announced that they collected nearly 600 pounds of prescription drugs during last weekend's National Prescription Drug Take-Back Day.

The Michigan State Police partnered with the Drug Enforcement Agency and other local law enforcement agencies to help provide a safe, convenient and responsible venue for citizens to dispose of unwanted and unused prescription drugs.

In Flint, troopers collected 101 pounds. The next highest city was Rockford with 70 pounds.

All 29 MSP posts participated in the one-day effort by serving as drop-off points for citizens to discard expired, unused and unwanted medication for destruction. The service was free and anonymous with no questions asked.
