Several drug take-back locations were held around the Heartland for the 4th National Prescription Drug Take Back Day.
The Drug Enforcement Administration gave giving the public another opportunity to prevent pill abuse and theft by disposing of expired, unused and unwanted prescription drugs.
Authorities in Williamson County say they participate for two reasons.
To keep prescription drugs from falling into the wrong hands and out of water supplies around the nation.
Local law enforcement agencies across the Heartland teamed up with the agency to help get rid of unwanted medications and used medical supplies.
Police say the dangers of these drugs sitting around can cause big problems.
"The DEA worries about maybe some mix up when a person's taking medicine, mixing up prescriptions or taking the wrong medicine," said Deputy Brian Murrah. "Something like that would cause medical issues. and law enforcement worries about prescription medication because of the abuse of the prescription pills. It's a big problem."
Police say teens in junior high and high school are abusing prescription medication more than any other age group in America.
In Jackson, Mo., people just drove through the fire department to drop off their unwanted drugs.
It's part of the Drug Enforcement Administration's push to prevent pill abuse.
More than 70-pounds of unwanted medications filled boxes at the Jackson location on Saturday.
According to the Carbondale Police Department, last October Americans turned in 377,080 pounds, or 188.5 tons, of prescription drugs at over 5,300 sites operated by the DEA and nearly 4,000 state and local law enforcement partners.
In the previous take back events, DEA and its partners took in almost a million pounds, or nearly 500 tons of pills.
