Between 10 and 30 percent of all prescription and over-the-counter drugs sold are left unconsumed, according to a State of Washington report, and all those leftover medications pose significant risks to public health and the environment. Drugs that are flushed down the toilet or tossed in the trash can – rather than properly disposed of – can end up in oceans and waterways, threatening both marine life and human health. Meanwhile, many individuals don’t get rid of their unused medications at all; they simply store the drugs in their medicine cabinets – a practice that can lead to drug misuse and abuse.
