Drugs such as antibiotics, insulin and nitroglycerin spoil quickly and can threaten human health. On the other hand, many drugs keep long past their expiration date, especially if kept sealed. Consumers and pharmacies lose money when they throw out deceptively unexpired drugs. A 2008 report by the American Society of Health-System Pharmacists reports that hospital CEO's say that “Drugs offer the single greatest opportunity for cost savings,” but not all pharmacies track which drugs typically expire nor their lost value.
Additionally, improperly disposed drugs can end up in the water supply where they can affect aquatic and terrestrial animals, including humans. People may experience the side effects of drugs contaminating water or they may negatively interact with sick people's current drug regimen.
