Proper disposal of drugs, medications can help keep our water safe. Please do not flush down a toilet. There are many places for proper disposal. Narcotics or controlled substances may require special handling. Studies show that medicines flushed down the drain can contaminate our lakes and streams, which can hurt fish and other aquatic wildlife, and end up in our drinking water. This is because most existing municipal wastewater treatments systems cannot remove medications from the wastewater. Some medications, such as hormones and antidepressants, interfere with the reproduction and normal growth of many aquatic species, such as frogs and fish. Links to studies are found below.
Hopefully the below list is a starting point for proper disposal and places available. Please share.
