10 Things You Should Never Pour Down the Drain
Medication

The Dangers of Disposing of Medication in Drains
Many people mistakenly believe that flushing medication is safe. They assume pills dissolve quickly, but this is not true. Instead, many medicines can contaminate the water supply, creating environmental and health risks.
Flushed medications do not vanish. They may remain whole or partially dissolve, polluting water sources. Filtration systems can remove most microbes, but they are not designed to filter pharmaceuticals. Traces of drugs can persist in drinking water and the environment, harming aquatic life and affecting humans.
Medication in water can disturb animal hormones, causing reproductive issues and population declines. It can also contribute to antibiotic resistance, as leftover antibiotics in water influence bacteria.
