Nicotine Poisoning: Symptoms, Causes and How Long It Lasts

Nicotine poisoning happens when the body takes in more nicotine than it can process. It is rare in adults, a bigger risk for children and different from a short-lived bad reaction to nicotine. This guide covers symptoms, causes, duration and when to get help.

Key Takeaways

Nicotine poisoning can overstimulate the nervous system.
Nicotine poisoning is rare in adults but can happen when products are swallowed.
Children are far more vulnerable than adults.
Symptoms tend to appear in two stages.
Less severe cases usually pass within 1–2 hours.

What Is Nicotine Poisoning?

Nicotine poisoning, also called nicotine toxicity or nicotine overdose, happens when nicotine builds up in the bloodstream faster than the body can process it, overstimulating the nervous system.

Nicotine is a chemical produced by the tobacco plant. It is found in cigarettes and shisha tobacco, and in nicotine pouches, gum, patches and e-liquids. Read what is nicotine?

Bad Reaction vs Nicotine Poisoning

A Bad Reaction to Nicotine

A bad reaction is temporary and not toxic. It is usually caused by sensitivity, too much nicotine too quickly, swallowing nicotine-rich saliva, dehydration or an empty stomach.

Symptoms include nausea, dizziness, headache and a faster heartbeat, and usually pass within minutes. This is closely related to a nicotine rush.

Nicotine Poisoning

Nicotine poisoning is usually caused by swallowing nicotine products, especially liquid nicotine or pouches, and is most often seen when children swallow them by accident.

	Bad reaction	Nicotine poisoning
Cause	Sensitivity, too much too fast, empty stomach	Excessive nicotine, usually swallowed
Severity	Temporary	Potentially life-threatening
What to do	Remove the product, drink water, rest	Call 997 for emergency care

The Two Stages of Nicotine Poisoning

Small amounts of nicotine stimulate the nervous system, while large amounts slow it down. This is why symptoms tend to appear in two stages.

Stage One: About 15 Minutes to 1 Hour

Nausea and vomiting
Excess saliva and abdominal pain
Pale skin and sweating
Faster heart rate, higher blood pressure and rapid breathing
Shaking, muscle twitching, headache and dizziness

Stage Two: About 30 Minutes to 4 Hours

Loss of coordination, seizures and diarrhoea
Low blood pressure and a slow or irregular heart rate
Muscle weakness and shallow breathing
Shock or coma in severe cases

If you notice vomiting, confusion or breathing problems, stop using nicotine and call 997 (Saudi Red Crescent), or 911 in the Riyadh, Makkah and Eastern regions immediately. For health advice, call the Ministry of Health on 937.

How Long Does Nicotine Poisoning Last?

Less severe cases usually resolve within 1–2 hours. Severe cases can last 18–24 hours and need medical care.

Nicotine Poisoning in Children

Children can become seriously ill from much smaller amounts of nicotine than adults. Liquid nicotine is especially dangerous, even on the skin.

Keep all nicotine products, including cans and used pouches, out of reach of children and pets. If a child swallows any nicotine product, get emergency help straight away.

Why Nicotine Affects People Differently

How your body processes nicotine depends on genetics and liver enzymes, as well as age, sex and medication. Slow metabolisers keep nicotine in the body for longer. See how long nicotine stays in your body.

Conclusion

Nicotine poisoning is rare in adults but serious, and children are most at risk. Know the difference between a short-lived bad reaction and poisoning, keep products away from children and pets, and call 997 (Saudi Red Crescent), or 911 in the Riyadh, Makkah and Eastern regions if symptoms are severe.
