Substances considered harmless or helpful in daily use can be deadly or do serious harm if over-consumed or misused. And substances that are thought of as harmful or toxic often have no hurtful effect in small doses.

- Caffeine - The central nervous system and heart are among the body systems affected by caffeine, With caffeine in so many products (coffee, tea, energy drinks, over-the-counter medications), it is easy to take in harmful amounts.
- Medications - Both prescription and over-the-counter medications can be harmful if not taken exactly as indicated; accidental drug misuse accounts for a great many hospitalizations and deaths.
- Water - Even a substance as critical to sustaining life as water can be toxic. Drinking massive quantities of water in a short period of time can cause death.
