How Many Deaths from Vaping in the World

As vaping continues to grow in popularity across the globe, questions about its safety and potential long-term health effects remain important. One of the most pressing concerns is whether vaping has caused deaths and, if so, how many. While vaping is widely considered a less harmful alternative to smoking, it is not without risks. The difference between legal, regulated nicotine vapes and unregulated or illicit products is also significant when examining reported deaths. This article provides a clear, factual overview of vaping-related fatalities worldwide, what caused them, how they compare to smoking-related deaths, and what this means for public health policy and consumers.

Understanding the Scope of Vaping and Global Use

Vaping has been adopted by millions of people worldwide as an alternative to smoking traditional tobacco. The World Health Organization estimates that there are over 80 million adult vapers globally. Most use regulated nicotine-based e-liquids, which are tightly controlled in regions such as the UK and Europe.

In countries where vaping is regulated, such as the UK, Canada, and New Zealand, health authorities generally consider it significantly less harmful than smoking. However, in other regions, particularly where black-market or homemade e-liquids are common, the safety profile changes drastically. It is within these unregulated markets that most severe health incidents and deaths linked to vaping have occurred.

Recorded Deaths Linked to Vaping

Globally, confirmed deaths directly caused by vaping remain extremely rare compared to smoking. The vast majority of cases that have been investigated were linked to a specific outbreak of lung injury that occurred in the United States in 2019, known as EVALI (E-cigarette or Vaping Product Use-Associated Lung Injury).

During the EVALI outbreak, the U.S. Centers for Disease Control and Prevention (CDC) recorded approximately 68 confirmed deaths and more than 2,800 hospitalisations. Investigations revealed that these cases were overwhelmingly linked to illicit vaping liquids containing tetrahydrocannabinol (THC) and vitamin E acetate, an oil-based additive that damages lung tissue when inhaled. These were not standard nicotine e-liquids sold in regulated stores but illegal products purchased from unverified sources.

Outside of the EVALI outbreak, confirmed vaping-related deaths are extremely few. Global public health data up to 2025 show no major outbreaks or large-scale fatalities associated with regulated nicotine vaping products. Most deaths attributed to vaping in news reports or medical journals stem from misuse of devices, contaminated or counterfeit liquids, or pre-existing health conditions exacerbated by vaping.

Why Deaths from Vaping Are Rare in Regulated Markets

In countries like the UK, the European Union, and Australia, vaping products must comply with strict safety regulations. Under the EU’s Tobacco Products Directive (TPD) and UK law, all e-liquids containing nicotine are limited to 20 mg/ml in strength, must not contain harmful additives such as diacetyl or vitamin E acetate, and must be produced in sterile, controlled environments.

These safety measures significantly reduce the risk of acute health events. Reputable manufacturers are required to submit ingredients and emissions data to regulatory authorities before their products can be sold. This contrasts with unregulated markets, where users may purchase untested liquids that could contain toxic or oil-based substances not intended for inhalation.

Vaping-related fatalities in regulated regions are exceptionally rare because the e-liquids used do not contain the substances responsible for the EVALI crisis. The most common risks associated with legal vaping involve minor side effects such as throat irritation or temporary coughing, not life-threatening injuries.

Comparing Vaping Deaths to Smoking Deaths

To understand the scale of vaping-related deaths, it helps to compare them to tobacco-related deaths worldwide. According to the World Health Organization, smoking kills more than eight million people every year, including about 1.3 million non-smokers exposed to second-hand smoke. These deaths result from cancers, heart disease, chronic lung conditions, and stroke caused by long-term exposure to tar, carbon monoxide, and thousands of toxic chemicals in tobacco smoke.

In comparison, fewer than one hundred confirmed deaths globally have been directly linked to vaping since its invention in the early 2000s, and nearly all of those were due to contaminated, unregulated products. This stark difference in mortality highlights vaping’s reduced risk when used correctly and with legal products.

While long-term research on vaping’s effects is still ongoing, current evidence suggests that switching from smoking to regulated nicotine vaping reduces exposure to harmful toxins by up to 95 per cent. However, vaping should still be viewed as a harm reduction tool, not a risk-free activity.

EVALI: The 2019 Vaping Lung Injury Outbreak

The 2019 EVALI outbreak remains the most significant vaping-related health crisis ever recorded. Most cases occurred in the United States, and extensive research has since identified vitamin E acetate as the primary cause. This substance was used as a thickening agent in illicit THC vape cartridges and caused severe lung damage when inhaled.

Symptoms included shortness of breath, chest pain, fever, and gastrointestinal distress. Many patients required hospitalisation, and some died due to respiratory failure. Importantly, investigations found no link between regulated nicotine vaping products and these illnesses. Instead, the issue stemmed from black-market THC liquids that contained oil-based ingredients unsafe for inhalation.

Following the outbreak, the CDC and other agencies issued warnings against using unregulated vape products or tampering with e-liquids. Since then, cases of EVALI have dramatically declined, with only sporadic reports worldwide. The event served as a lesson in the importance of strict regulation, quality control, and consumer awareness.

Are There Ongoing Deaths Linked to Vaping?

As of 2025, there have been no major new global outbreaks of vaping-related deaths similar to the EVALI crisis. Sporadic cases occasionally appear in medical literature, but these are typically isolated incidents involving misuse, pre-existing health problems, or exposure to unregulated products.

For example, some cases involve battery explosions caused by improper charging or damage to the device. These are rare but can result in burns or injury. Such incidents highlight the importance of proper device maintenance and following manufacturer safety instructions.

There have also been isolated reports of allergic reactions or respiratory complications in individuals sensitive to ingredients such as propylene glycol or certain flavourings. However, these cases are extremely rare and generally non-fatal.

The global data continues to show that deaths directly attributable to vaping nicotine-based e-liquids remain statistically insignificant when compared to other causes of preventable illness and death, including smoking, alcohol consumption, and poor diet.

Understanding the Difference Between Correlation and Causation

When reports mention vaping-related deaths, it is crucial to distinguish between correlation and causation. A person may have vaped before experiencing a health problem, but that does not necessarily mean vaping caused the issue. Many cases involve individuals who already had serious underlying conditions such as asthma, heart disease, or compromised immune systems.

Medical investigations look for direct evidence linking vaping to the cause of death, such as lung damage directly attributable to inhaled substances. In most confirmed cases, the link is to unregulated or adulterated products, not to standard nicotine e-liquids.

This distinction matters because misinformation can lead to confusion among smokers considering switching to vaping as a less harmful alternative. Public health experts stress that while vaping should not be used by non-smokers or young people, it remains a valuable tool for adult smokers trying to quit.

Vaping-Related Deaths vs Other Substance Risks

Comparing vaping to other common risks provides perspective. Alcohol is responsible for around three million deaths globally every year. Air pollution causes more than four million deaths annually. In contrast, fewer than one hundred deaths have been directly linked to vaping since it became widespread nearly two decades ago.

While vaping carries potential long-term risks that are still being studied, the immediate danger is significantly lower than many other lifestyle factors. The difference lies in the absence of combustion. Cigarettes burn tobacco, producing thousands of harmful chemicals, while vaping heats a liquid to produce vapour without burning it. This fundamental difference explains why vaping deaths are so rare.

Why Regulation Is Key to Preventing Deaths

The global vaping market is divided between regulated and unregulated products. Regulated markets such as the UK, EU, Canada, and New Zealand require testing and ingredient disclosure for all e-liquids. These measures ensure that harmful additives like vitamin E acetate are never included in legal nicotine products.

In contrast, countries with weak or no regulation are more vulnerable to counterfeit and homemade liquids. These may contain oils, contaminants, or industrial chemicals that are dangerous when inhaled. Consumers in such regions are at higher risk of harm.

Public health experts agree that robust regulation, enforcement, and education are the best defences against vaping-related deaths. Ensuring that users have access to safe, well-tested products and accurate information prevents the kind of crises seen with EVALI.

The Role of Public Health Messaging

Misinformation about vaping has caused confusion among the public. Some reports exaggerate the risks, leading smokers to believe that vaping is just as dangerous as smoking, which is not supported by scientific evidence. This misunderstanding can discourage smokers from switching to safer alternatives, ultimately causing more harm than good.

The UK’s approach provides an example of balanced public health messaging. The National Health Service promotes vaping as a harm reduction tool for adult smokers while emphasising that it should not be used by non-smokers or young people. This approach acknowledges both the benefits and the risks of vaping, helping the public make informed decisions.

Long-Term Uncertainty and Ongoing Research

Although short and medium-term evidence indicates that vaping is far less harmful than smoking, scientists continue to study potential long-term effects. Because vaping has only been widespread for about fifteen years, there is limited data on health outcomes over decades of use.

Researchers are monitoring whether long-term inhalation of vapour could lead to respiratory or cardiovascular issues. So far, there is no evidence of a significant increase in mortality among vapers, but ongoing research will provide a clearer picture in the years ahead.

Until more is known, the safest approach remains to use vaping as a transitional tool to quit smoking, not as a lifelong habit. For non-smokers, avoiding vaping altogether eliminates any potential risk.

Can Vaping Ever Be Fatal in Normal Use?

For most users, regulated vaping poses very low risk of death. However, as with any electronic product, accidents can occur if devices are used improperly. Battery malfunctions, such as short circuits or overheating, can cause injuries. These cases are extremely rare and usually linked to damaged batteries or misuse rather than the act of vaping itself.

Nicotine poisoning is another theoretical risk, but it is nearly impossible through normal vaping. The body absorbs nicotine gradually through vapour, and most people self-regulate their intake naturally. Poisoning cases generally involve ingestion of concentrated nicotine liquid, not inhalation through vaping devices.

The Global Picture in 2025

As of 2025, there have been no widespread outbreaks of vaping-related deaths anywhere in the world. The EVALI crisis remains a historical outlier caused by unregulated THC products, not standard nicotine vapes. Public health data from the UK, Europe, and other developed markets continue to show no significant rise in mortality linked to vaping.

Regulated vaping remains an effective harm reduction tool for adult smokers, with far fewer health risks than tobacco. However, it should be used responsibly, purchased only from reputable sources, and avoided by non-smokers.

Conclusion

The total number of confirmed deaths from vaping worldwide remains extremely low, especially when compared to the millions who die each year from smoking-related illnesses. Most recorded fatalities were linked to illegal or unregulated products containing dangerous additives like vitamin E acetate rather than to standard nicotine e-liquids.

In countries with strong safety standards such as the UK, vaping-related deaths are virtually nonexistent. This demonstrates that regulation and responsible use make vaping one of the most effective harm reduction tools available to smokers.

While vaping is not entirely risk-free, it poses a fraction of the danger that smoking does. Continued research, public education, and strict regulation will ensure that vaping remains as safe as possible for adult smokers while protecting non-smokers and young people from potential harm.
