A poison is a substance that has toxic
effects and may injure you or make you sick if you are exposed to it. Poisons
can be found everywhere, from simple household cleaners to cosmetics to
houseplants to industrial chemicals. Even medicines that are taken in the wrong
dose, at the wrong time, or by the wrong person can cause a toxic effect.
Poisonous substances can hurt you if they are swallowed, inhaled, spilled on
your skin, or splashed in your eyes. In most cases, any product that gives off
fumes or is an aerosol that can be inhaled should be considered a possible
poison. More than 90% of poisonings occur in the home.
children have the highest risk of poisoning because of their natural curiosity.
More than half of poisonings in children occur in those who are younger than
age 6. Some children will swallow just about anything, including unappetizing
substances that are poisonous. When in doubt, assume the worst. Always believe
a child or a witness, such as another child or a brother or sister, who reports
that poison has been swallowed. Many poisonings occur when an adult who is
using a poisonous product around children becomes distracted by the doorbell, a
telephone, or some other interruption.
Young children are also at high risk for accidental poisoning from nonprescription and prescription medicines. Even though medicine bottles are packaged to prevent a child from opening them, be sure to keep all medicines away from where children can reach them.
Teenagers also have an
increased risk of poisonings, both accidental and intentional, because of their
risk-taking behavior. Some teens experiment with poisonous substances such as
by sniffing toxic glues or inhaling aerosol substances to get "high." About
half of all poisonings in teens are classified as
suicide attempts, which always requires medical
