Vape poisoning is rare, but it can be serious if it happens.
In the UK, most cases are linked to unregulated vapes or taking in too much nicotine too quickly;
High-strength e-liquids and accidental exposure increase the risk;
Spotting symptoms early and knowing when to get medical help can prevent long-term harm and save lives.
Vape Poisoning Introduction
Reports of “vape poisoning” have sparked concern across the UK, but the term covers different issues. A realityTV star’s widely publicised hospitalisation for Ecigarette or VapingAssociated Lung Injury (EVALI) shows how inhaling unregulated substances can cause severe lung and heart complications. At the same time, there are warnings about nicotine overdose, a separate problem that can arise if large amounts of nicotine are ingested, inhaled or absorbed through the skin. Understanding the differences, symptoms and treatments will help vapers and their families stay safe.
E-cigarettes are tightly regulated in the UK and switching from smoking to regulated vapes reduces exposure to harmful toxins. However, vaping is not riskfree, and children or nonsmokers should never vape. Read on to learn how to recognise signs of nicotine poisoning, what to do if it occurs and how to minimise risk.
EVALI vs. Nicotine Poisoning
What is EVALI?
EVALI is an inflammatory lung injury linked to substances in some eliquids. In the highprofile case above, chemicals triggered a coronary artery vasospasm, where arteries supplying the heart suddenly clamped down, leading to a heart attack. EVALI symptoms include severe chest pain, breathing difficulties and prolonged coughing. If you experience these, seek emergency medical care immediately.
EVALI Key points
EVALI is a lung injury, not a nicotine overdose. It is associated with harmful additives or contaminants in eliquids.
Symptoms include chest pain, shortness of breath, cough and, in rare cases, heart complications.
Seek urgent medical attention if you suspect EVALI; early treatment improves outcomes.
EVALI is a lung injury caused by inhaling harmful additives or contaminants. Nicotine poisoning is caused by ingesting or absorbing too much nicotine. EVALI can lead to heart complications such as coronary vasospasm and should be treated urgently
What is Nicotine Poisoning?
Nicotine poisoning occurs when the body absorbs too much nicotine. It can happen through inhalation, ingestion or skin contact. While toxic doses are much higher than commonly believed, children are especially vulnerable. Accidental ingestion of eliquid by children or pets is the biggest risk.
Symptoms
Early stage (within 15–60 minutes): nausea, vomiting, increased salivation, abdominal pain, sweating, elevated heart rate and blood pressure, tremors and dizziness.
Late stage (30 minutes – 4 hours): diarrhoea, slowed heart rate, low blood pressure, abnormal heart rhythms, muscle weakness or paralysis, breathing difficulties and coma.
Symptoms may last 1–2 hours after mild exposure or up to 24 hours after severe exposure.
Death is rare but usually results from respiratory failure and cardiovascular collapse
How Likely Is Nicotine Overdose From Vaping?
For vapers using regulated products, nicotine overdose from inhalation is extremely unlikely. Vapers would need to inhale unrealistically large volumes of highstrength ejuice in a short time to reach toxic blood levels. Studies show plasma nicotine levels in experienced vapers are 80 times lower than those recorded in fatal nicotine overdoses. Mild symptoms such as nausea, headaches or dizziness simply indicate you should take a break or reduce your nicotine strength.
Take-home messages
Overdose by vaping alone is implausible. Even with highstrength liquids, typical use doesn’t deliver enough nicotine to be dangerous.
Nausea and headaches after long vaping sessions are signs you’ve had too much; stop vaping and you’ll recover quickly.
Higher risk from ingestion or skin contact. Drinking eliquid or spilling large amounts on the skin can be dangerous, especially for children or pets.
Risks of Ingesting E-Liquid and Skin Exposure
Ingesting e-liquid
Adults who accidentally swallow a small amount of lowstrength ejuice may feel nauseous or vomit, but serious consequences are rare. However, children can ingest potentially lethal doses because of their small body weight.
Keep eliquids and nicotine bases locked away from children and pets. Highstrength nicotine base used for DIY mixing (sometimes 72 mg/ml) poses a serious risk; as little as a quarterteaspoon could be fatal to a child.
If a child drinks eliquid, call emergency services (999) or NHS 111 immediately. Serious symptoms such as persistent vomiting, dizziness, palpitations, breathing difficulties, seizures or loss of consciousness warrant emergency care.
Skin exposure
Nicotine can be absorbed through the skin, but studies suggest absorption from spills is slow and quantities are small. The realworld risk for adults is low because most people wash spills off quickly.
For children, spills on the skin are more serious due to low body weight. Wash any spills immediately and monitor for symptoms; if in doubt, seek medical advice.
When mixing your own ejuice, wear gloves and protective clothing to prevent skin contact and store nicotine base safely.
What To Do if Symptoms Occur
Mild symptoms after vaping
Stop vaping immediately and rest. Drink water and avoid nicotine until symptoms pass.
If nausea, headache or dizziness persists despite resting, reduce your nicotine concentration or vape less frequently.
Swallowed eliquid
Assess how much and what strength was swallowed. A small sip of lowstrength ejuice may only cause nausea and vomiting; drink water and call NHS 111 for advice.
For larger amounts, particularly in children or pets, seek medical help immediately.
Emergency care may involve activated charcoal to reduce absorption, intravenous fluids for low blood pressure and medication to stabilise heart rate.
Skin contact
Wash the affected area with soap and water immediately.
Remove contaminated clothing and ventilate the area if there’s a large spill.
Watch for nausea, vomiting or dizziness; seek medical advice if symptoms develop.
Vape Poisoning Prevention and Safety Tips
Buy regulated products. UK vaping products are regulated by the MHRA and must list all ingredient. Avoid unregulated or homemade liquids, which may contain harmful additives.
Store eliquids safely. Keep all nicotine products in childresistant containers and locked away from children and pets.
Use appropriate nicotine strengths. Choose a nicotine strength that satisfies cravings without causing dizziness or nausea. Reduce strength or frequency if you experience mild symptoms of too much nicotine.
Avoid multiple nicotine sources. Using nicotine gum, lozenges or patches while vaping can increase overdose risk.
Wash spills immediately. Clean any eliquid off skin and surfaces at once and launder contaminated clothing.
Dispose of empty bottles properly. Seal used containers and dispose of them safely to prevent children or pets from accessing residual nicotine.
Vape Poisoning FAQ
Can vaping cause nicotine poisoning?
It is extremely unlikely to overdose on nicotine by vaping alone. You would need to vaporise and absorb far more nicotine than is practical. Mild symptoms like nausea or headaches are signs to stop and take a break. Serious nicotine poisoning usually results from swallowing eliquids or using multiple nicotine products at once.
What are the signs of nicotine poisoning?
Early signs include nausea, vomiting, dizziness, headache, increased salivation and abdominal pain. Late signs include diarrhoea, slowed heart rate, low blood pressure, muscle weakness, breathing difficulties and loss of consciousness. Seek medical help if severe symptoms appear.
What should I do if someone drinks e-juice?
If a small amount of lowstrength ejuice is swallowed, the person may feel sick but will usually recover after vomiting. For children or larger amounts, call NHS 111 or 999 immediately. Emergency treatment may include activated charcoal and supportive care
Is EVALI the same as nicotine poisoning?
No. EVALI is a lung injury caused by inhaling harmful additives or contaminants. Nicotine poisoning is caused by ingesting or absorbing too much nicotine. EVALI can lead to heart complications such as coronary vasospasm and should be treated urgently
Are vapes regulated in the UK?
Yes. The MHRA regulates nicotinecontaining vapes and requires manufacturers to provide ingredient lists. This regulation bans ingredients such as diacetyl, which is linked to “popcorn lung,” and ensures products meet safety standards.
Should children or non-smokers vape?
No. Vaping is intended to help smokers quit and is not riskfree. Children and nonsmokers should never vape.
Final Thoughts
“Vape poisoning” can refer to rare but serious lung injuries (EVALI) or to nicotine overdose. Regulated vaping is significantly less harmful than smoking and is a proven aid for quitting. However, nicotine is a potent substance, and ingesting or absorbing too much can be dangerous. Recognise the symptoms, store eliquids safely, buy regulated products and seek medical help when necessary to ensure safe vaping in the UK.
