To prevent the abuse of anesthetic drugs, such as fentanyl and propofol, hospitals dispose of unused anesthetics. In countries such as the United Arab Emirates, Japan, and China, some hospitals abide by local policies by dumping these unused anesthetics into sewers (1–3). This disposal method contravenes environmental principles and threatens public health. These countries should implement policies to require and regulate the safe disposal of anesthetics by hospitals.
