The U.S. Drug Enforcement Administration is holding its national "Take Back" event Saturday. Local police will set up sites where you can drop off old and unwanted prescription drugs.

Dee Dee Gunther is with the Roseville Police Department. She says home medicine cabinets are a leading source of pills for teens who abuse drugs.

Gunther also says flushing meds down the toilet is an environmental hazard.

"Even though the water's filtered before it's discharged into the creek, they have found trace levels of such things in the creek and in the water supplies so this is a much better way to get rid of those drugs."

You can drop off old pharmaceuticals at all five high schools in Roseville on Saturday between 10 AM and 2 PM.

The Sacramento County Sheriff's Department is also setting up drop-off sites at the Rancho Cordova Police Department, the Sheriff's Garfield Station and the Sheriff's Florin Station.
