Nicotine isn’t just addictive—it’s a toxic substance. People often forget that the same drug that hooks smokers and vapers is also used in insecticides to kill pests.

The effects of nicotine go far beyond addiction; in high doses, nicotine is a poison that can harm or even kill. Whether it’s through cigarettes, vapes, patches, gums, or accidental ingestion, the threat of nicotine poisoning is real.

This article explores nicotine poisoning in depth: its symptoms, how it happens, who’s at risk, and what to do in an emergency. Most importantly, it offers a way out. You’ll learn how quitting nicotine with Allen Carr’s Easyway can not only free you from addiction but also protect your life.

Where is nicotine found?

Nicotine is a naturally occurring alkaloid found in tobacco plants. It’s also found in much smaller amounts in plants like tomatoes, potatoes, and aubergine/eggplants – but these trace quantities are harmless.

The danger lies in:

Cigarettes

Each one contains about 10–12 mg of nicotine, but only 1–2 mg is absorbed by the smoker.

E-cigarettes/vapes

Levels vary wildly, but some pods contain as much as a pack of cigarettes.

Nicotine patches, gums, lozenges, nasal sprays

Often used in cessation programs, but still deliver substantial doses.

Liquid nicotine/e-juice

Concentrated forms are used for refilling vapes. A single bottle can contain hundreds of milligrams.

Insecticides

Historically, some pesticides contained nicotine sulphate, now mostly replaced due to toxicity.

Accidental ingestion

Especially dangerous for children and pets who may swallow nicotine gum, patches, or e-liquids.

How common is nicotine poisoning?

While not as common as other forms of poisoning, nicotine toxicity is on the rise – especially in children and vapers. Ingestion of even small amounts can cause serious symptoms.

A 2019 study in the journal National Institutes of Health found a nearly 900% increase in child nicotine poisoning cases from e-liquids between 2013 and 2019.

A total of 4,745 poisoning cases in the US between 2013 and 2017 involved children under five years old. 4% required hospital admission.

The rise in vaping among teens has introduced new dangers. Some teens intentionally overdose for “a buzz,” unaware that even a few millilitres of concentrated nicotine can be fatal.

What is a lethal dose of nicotine?

The generally cited lethal dose of nicotine for adults is 30–60 mg, which is equivalent to ingesting five cigarettes.

Newer studies suggest it may be closer to 500–1000 mg when ingested orally due to slower absorption.

But for children, even 1–4 mg/kg can be dangerous. That’s why childproof packaging is critical, especially with vape juice and why parents and caregivers must store nicotine products safely.

Inhalation, skin absorption, or accidental injection (e.g., via e-liquid in open wounds) increases the risk.

What are the signs and symptoms of nicotine poisoning?

Nicotine affects both the central nervous system and the cardiovascular system. The symptoms can occur within minutes and fall into two stages:

Early symptoms (excitatory phase) of nicotine poisoning:

  • Nausea and vomiting
  • Excessive salivation
  • Abdominal pain
  • Rapid heart rate (tachycardia)
  • High blood pressure
  • Anxiety or restlessness
  • Dizziness or headache

Late symptoms (depressive phase) of nicotine poisoning:

  • Slowed heart rate (bradycardia)
  • Low blood pressure
  • Muscle weakness or paralysis
  • Breathing difficulty
  • Convulsions
  • Coma
  • Death (in severe cases)

It’s a short road from stimulant to depressant – making early intervention critical.

How quickly does nicotine poisoning happen?

Very quickly. Symptoms may appear within 15–30 minutes of ingestion or exposure. With liquid nicotine, especially through skin or mucous membranes, it may take even less time.

The rapidity of onset is one of the greatest dangers. Someone might feel a slight headache or nausea and dismiss it, only for their condition to worsen rapidly.

Can a person overdose on nicotine from smoking alone?

It’s rare, but theoretically possible. The body naturally limits intake through nausea or dizziness, making it hard to smoke enough in a short time to reach fatal levels.

However, chain-smoking or using multiple nicotine sources simultaneously (e.g., cigarettes + gum + patches) can raise blood nicotine concentrations dangerously.

The real overdose risk lies with:

  • Vape cartridges/juices with high-concentration nicotine salts
  • Nicotine poisoning in children from ingestion
  • DIY e-juice mixing without protective gear

How long do nicotine poisoning symptoms last?

The symptoms usually peak within the first hour.
Mild cases resolve in 1–2 hours with no lasting harm.

However, severe cases may require hospitalisation and monitoring for 24 hours or longer.

In cases involving coma or respiratory failure, recovery may take weeks, and survivors may suffer permanent neurological or cardiac effects.

What causes nicotine poisoning?

The core cause of nicotine poisoning is nicotine overdose, which overwhelms the body’s receptors. Common causes include:

  • Ingesting e-liquids (common in toddlers and pets)
  • Skin exposure to concentrated nicotine
  • Overuse of nicotine patches, gums, or sprays
  • Mixing multiple nicotine products
  • Suicidal ingestion

Nicotine binds to nicotinic acetylcholine receptors (nAChRs) in the brain and body. Excessive use leads to receptor desensitisation, neuromuscular blockade, and central respiratory suppression.

When to seek emergency medical care

Call emergency services immediately (999 or 911) if you or someone else experiences:

  • Seizures
  • Difficulty breathing
  • Irregular heartbeat
  • Confusion or hallucinations
  • Loss of consciousness
  • Excessive vomiting, drooling, or sweating (especially in children)

Do not induce vomiting unless instructed by medical professionals. If skin contact occurred, wash thoroughly with soap and water.

In the U.S., you can also contact Poison Control at 1-800-222-1222.
