Hazardous Waste

Leftover or expired drugs can pose a number of serious environmental and health risks. If not disposed, unused drugs can lead to accidental poisonings, addiction or abuse. Drugs can also have health and environmental impacts when they end up in a landfill or are flushed down the toilet or drain. Wastewater treatment plants and septic systems are usually not equipped to treat pharmaceuticals and chemical compounds from these drugs can pass through treatment plants or septic systems to our rivers or groundwater. 

The Drug Take-Back Law (ORS 459A.200 to 459A.266) requires drug manufacturers to fund and develop a statewide drug take-back program that will provide safe and secure disposal of drugs for Oregon residents and other covered entities by July 1, 2021.

Option 2

If no sites or events are available, dispose of waste pharmaceuticals in the trash using these basic guidelines:

  1. Take waste pharmaceuticals out of their original containers and mix with an undesirable substance such as used cat litter, or coffee grounds.

  2. Place this mixture in a plastic bag or other sealable container, such as an empty plastic container.

  3. Place the sealed container with the mixture in the trash as close to garbage pickup time as possible, to prevent theft and misuse.
