Poisoning in the United States: Fact Sheet


Every day in the United States, nearly 87 people die as a result of unintentional poisoning, and another 2,277 are treated in emergency departments (ED).1
A poison is any substance, including medications, that is harmful to your body if too much is eaten, inhaled, injected, or absorbed through the skin. Any substance can be poisonous if too much is taken.
Poisonings are either intentional or unintentional. This fact sheet provides information on the problem of unintentional poisoning in the United States. If the person taking or giving a substance did not mean to cause harm, then it is an unintentional poisoning.
Unintentional poisoning includes the use of drugs or chemicals for nonmedical purposes in excessive amounts, such as an “overdose.” It also includes the excessive use of drugs or chemicals for non-recreational purposes, such as by a toddler.

The Problem

Information about both lead and carbon monoxide poisoning can be found on other CDC web pages; see sources of additional information below for the relevant websites.
  • In 2009, 31,758 (76 percent) of the 41,592 poisoning deaths in the United States were unintentional, and 3,349 (8 percent) were of undetermined intent.1 Unintentional poisoning death rates have been rising steadily since 1992.1
  • Unintentional poisoning was second only to motor vehicle crashes as a cause of unintentional injury death for all ages in 2009. Among people 25 to 64 years old, unintentional poisoning caused more deaths than motor vehicle crashes.1
  • In 2010, unintentional poisoning caused about 831,295 emergency department (ED) visits.1
  • 206,479 (25 percent) of these ED visits resulted in hospitalization or transfer to another facility.1
  • In 2010, poison control centers reported receiving calls about 2.4 million human poison exposure cases.2
  • Between 2004 and 2005, an estimated 71,000 children (<18 years of age) were seen in EDs each year because of medication poisonings (excluding abuse and recreational drug use). Over 80 percent were because an unsupervised child found and consumed medications.3

Most Common Poisons

In 2008, 28,171 (91 percent) of all unintentional poisoning deaths were caused by drugs. The class of drugs known as prescription painkillers, which includes such drugs as methadone, hydrocodone, and oxycodone, were most commonly involved, followed by cocaine and heroin.4
  • Among those treated in EDs for nonfatal poisonings involving nonmedical use of prescription or over-the-counter drugs in 2009, opioid pain medications and benzodiazepines (such as Valium) were involved most frequently.5Nonmedical use includes misuse, abuse or otherwise not taking a drug as prescribed.
  • Among children, ED visits for medication poisonings (excluding misuse or abuse) are twice as common as poisonings from other household products (such as cleaning solutions and personal care products).3


  • In 2005, poisonings led to $33.4 billion in medical and productivity costs.6

Groups at Risk for Poisoning

Among those who died from unintentional poisoning in 2009:
  • Men were nearly twice as likely as women to die;
  • American Indians/Alaska Natives had the highest death rate, followed by Whites and then Blacks
  • The highest mortality rates were among people 45-49 years of age; and
  • The lowest mortality rates were among children less than 15 years old because they do not abuse drugs as frequently as older people.1
Among people who unintentionally poisoned themselves and received treatment in emergency departments in 2010:
  • Men were 1.6 times more likely than women to make such ED visits;
  • The highest rates were in the 45-49 year old age group.1
Among children, ED visits for medication poisonings are most common in children <6 years of age.
  • One out of every 180 two-year-olds visits an emergency department for a medication poisoning.3

Policy Impact: Prescription Painkiller Overdoses

Through this publication, CDC supports state-based efforts to reduce prescription drug abuse while ensuring patients have access to safe, effective pain treatment.
