Which of the following is classified as pharmaceutical waste?

Pharmaceutical waste specifically refers to discarded medications and their containers that can be harmful to the environment and public health. Drug vials, which are containers that hold pharmaceutical products, such as tablets, liquids, or injections, fall squarely within this category. They can retain residues of the drugs they once contained, necessitating careful handling and disposal to prevent accidental exposure or environmental contamination.

On the other hand, broken glassware is categorized differently as it pertains primarily to laboratory waste, while food waste relates to organic waste that doesn't contain pharmaceutical substances. Chronic exposure involves health impacts resulting from long-term interaction with harmful substances, but it does not classify waste itself. Therefore, drug vials are clearly identified as pharmaceutical waste, highlighting the importance of appropriate disposal practices to safeguard health and the environment.
