What is a poison?

A poison is anything that can harm someone if it is:

  • Used in the wrong way
  • Used by the wrong person
  • Used in the wrong amount

Some poisons may be harmful if they come into direct contact with your eyes or skin. Others may be toxic if you breathe them or swallow them. Poisons can come in four forms: solids (such as pain medicine pills or tablets), liquids (such as household cleaners, including bleach), sprays (such as spray cleaners), and gases (such as carbon monoxide, or CO).1

Most consumer products are safe if label directions are followed, but some can be poisonous if used incorrectly. Visit the FAQs (Frequently Asked Questions) section and Prevention Tips for a list of different poisons and what you can do to avoid them.

Who is at risk?

You may think that poisoning affects only a certain group of people—such as young children or older adults. This, however, is not true. Anyone, regardless of their age, race, ethnicity, or career, can be poisoned. Poisonings happen more often than you think.

In 2008, 2.5 million people called a poison center because someone had been exposed to a poison.1 Children under age six accounted for half of all human poison exposures reported to poison centers.1 However, adults are also at risk. That year, more than three-quarters of all poisoning deaths reported to poison centers occurred among people ages 20 to 59.1

What are the risks throughout life?

Certain kinds of poisonings are common among specific age groups. For example, older adults specifically need to be aware of the poisoning risks involved with taking prescription medications. Children are commonly poisoned through painkillers, cosmetics, personal care or cleaning products, pest killers, and plants. Preteens through older adults are commonly poisoned through herbal products, prescription drugs, alcohol, over-the-counter medicines, and spoiled food.

People of all ages may be stung by a bee, splashed with a chemical, or exposed to carbon monoxide in their homes. People also may use a cleaning product without gloves.

For more information on how poisonings can affect everyone, refer to the What You Can Do and FAQs sections.
