10 Household Items You Should Never Pour Down Your Drain
Medication

The Risks of Disposing Medication Through Drainage Systems
Numerous individuals mistakenly assume that flushing medication remains safe. They believe pills dissolve rapidly, but this assumption proves incorrect. Instead, many pharmaceuticals can contaminate water supplies, creating environmental and health risks.
Flushed medications do not vanish. They might remain intact or partially dissolve, polluting water sources. Treatment systems can eliminate most pathogens, but they lack design for pharmaceutical removal. Drug traces can persist in drinking water and environments, damaging aquatic creatures and impacting humans.
Medication in water can disturb animal hormone systems, causing breeding problems and declining populations. It can also contribute to antibiotic resistance, as remaining antibiotics in water influence bacterial populations.
