Nicotine, found naturally in tobacco plants, is the chemical responsible for the addictive nature of cigarettes, cigars, and many e-cigarettes.
Until recent years, nicotine poisoning was a relatively rare occurrence and tended to be linked to exposure to insecticides containing the chemical. However, the popularity of vaping or e-cigarettes has seen an increase in reported cases.
Both adults and children can be affected by nicotine, with over 50 percent of cases of nicotine exposure reported to the American Association of Poison Control Centers (AAPCC) in 2014 occurring in children under 6 years of age.

How commonly is nicotine poisoning reported?
What forms of nicotine are most dangerous?
Children are most at risk of nicotine poisoning through eating cigarettes or nicotine-containing products, or drinking or touching liquid nicotine. Nicotine from e-cigarettes may be especially hazardous, as these products are not required to be childproof, and are available in flavors that appeal to children.
Adults who are unaccustomed to smoking and who try vaping are at greater risk of nicotine poisoning than adults who smoke regularly. Using a nicotine patch or chewing gum containing nicotine while smoking at the same time can also lead to nicotine overdose. Chewing or snorting tobacco tends to release more nicotine into the body than smoking.
Third-hand nicotine poisoning may also be an issue for adults, children, and pets. Vapors from e-cigarettes can stick to fabrics or other surfaces and then transfer to those who touch them.
A form of nicotine poisoning, known as Green Tobacco Sickness (GTS), can occur in those who harvest tobacco or work in tobacco processing factories.
Nicotine overdose depends on factors such as body weight and the source of the nicotine.

Nicotine affects the body in a variety of ways. It is both a sedative and a stimulant that impacts the heart, hormones, and digestive system.

Nicotine is most harmful when taken in quantities larger than those recommended (leading to nicotine poisoning) and when consumed in cigarettes or other products that contain a variety of chemicals that are detrimental to health including cigars.
Treatment for nicotine poisoning is usually carried out at a hospital. The treatments administered will depend on the amount of nicotine ingested and the symptoms experienced.
Activated charcoal may be used to bind with the nicotine in the stomach and take it out of the body.
If the person is experiencing breathing difficulties, a ventilator will be used to deliver oxygen.
Other supportive treatments, including medications, are used to manage seizures, low blood pressure, and abnormal heart rates.
If someone is experiencing nicotine poisoning symptoms, it is important to seek emergency medical attention.
Follow the directions of the medical personnel and do not force the person to vomit or give them any food or liquids.
For nicotine that was absorbed through the skin, rinse the affected area immediately with water for 15 minutes.
The most effective way to prevent nicotine poisoning is to stop using cigarettes and other nicotine-containing products.
Other preventative measures include:
- protecting the skin, especially when using liquids containing nicotine
- safely storing nicotine products away from children and pets
- correctly disposing of nicotine products – including cigarette butts and empty nicotine cartridges
People who wish to quit smoking or use of other nicotine products should consult their doctor for further information.
The outlook for those with nicotine poisoning depends on how much nicotine they have ingested and how quickly they seek treatment. With rapid medical treatment, most people make a full recovery without any long-term effects.
In rare cases, severe nicotine poisoning can be fatal.
