Several law enforcement agencies in Iowa are participating in the National Prescription Drug Take-Back Day on Saturday (April 28, 2018).

Hours of the event are 10 AM to 2 PM at various locations. The list of northeast Iowa drop-off sites is posted below.

Sponsored by the Drug Enforcement Administration (DEA), Drug Take-Back Day lets patients and their families dispose of unwanted, unused or expired medications. The service is free and anonymous, no questions asked.

Illicit substances such as marijuana are not part of this initiative. Injectable, IV solutions, inhalers and other compressed air cylinders will not be accepted.

The Take-Back event addresses a vital public safety and public health issue. According to DEA, medicines that languish in home cabinets are highly susceptible to diversion, misuse, and abuse. Rates of prescription drug abuse in the U.S. are alarmingly high, as are the number of accidental poisonings and overdoses due to these drugs.

Studies show that a majority of abused prescription drugs are obtained from family and friends, including from the home medicine cabinet. In addition, Americans are now advised that their usual methods for disposing of unused medicines -- flushing them down the toilet or throwing them in the trash -- both pose potential safety and health hazards.

Last fall, the public turned in 456 tons (912,000 pounds) of prescription drugs at more than 5,200 sites operated by the DEA and more than 4,200 of its state and local law enforcement partners. Overall, in 14 previous Take-Back events over the past eight years, DEA and its partners have taken in over 9 million pounds -- more than 4,500 tons -- of pills.

For more information about the disposal of prescription drugs or about the April 29 Take-Back Day event, go to the DEA Diversion or the Governor's Office of Drug Control Policy websites.
