LOS ANGLES, Calif.–Residents can safely dispose of unused and expired medications at participating police and sheriff’s stations on Saturday, authorities said today.

The Los Angeles County Sheriff’s Department and Los Angeles Police Department will hold disposal stations as part of the Drug Enforcement Agency’s National Take-Back Day.

The program allows residents to safely and anonymously drop off expired or unused prescriptions, over-the-counter medications, syringes and any other controlled substances, according the Sheriff’s Department. Flushing medicines down the drain can affect wildlife and interfere with wastewater treatment plants.

Visit one of the 21 sheriff’s drop-off stations including:

  • Altadena
  • Carson
  • Century
  • Compton
  • Crescenta Valley
  • East Los Angeles
  • Industry
  • Lakewood
  • Lancaster
  • Lomita
  • Malibu/Lost Hills
  • Marina Del Rey
  • Norwalk
  • Palmdale
  • Pico Rivera
  • San Dimas
  • Santa Clarita Valley
  • Temple
  • Walnut/Diamond Bar
  • West Hollywood
  • South Los Angeles

Sheriff’s Department stations accept prescription medications for disposal 24 hours a day throughout the year, in addition to Saturday’s event.

Last year the department collected and disposed of 8,055 pounds of medications, 288,010 syringes and 3.75 pounds of illicit drugs, according to the Sheriff’s Department.
