Vape or Cigarette: The Ultimate Comparison for Switchers

Nils Große •Updated 03.02.2026 •9 min read

Are you considering switching from tobacco cigarettes to a vape? You're not alone. More and more smokers are looking for a cigarette alternative and inevitably come across the topic of e-cigarettes. But the flood of information on the internet is enormous and often contradictory. What's behind the hype? Is vaping more harmful than smoking, or is it actually the better choice?

This comprehensive guide provides you with an honest, fact-based comparison. We examine the key differences in the areas of health, addictive potential, and costs, and offer you a practical guide to switching from cigarettes to vapes.

At a Glance: E-Cigarette vs. Cigarette in Direct Comparison

To give you a quick overview, we have outlined the most important points side by side:

Important Note

This comparison refers to e-cigarettes (vapes) that vaporise liquids. They are often confused with tobacco heaters (e.g. IQOS), in which real tobacco is heated rather than burned. Although these are also considered reduced-risk compared to cigarettes, the operating principle is different and will not be covered here.

Based on the principle of the e-cigarette, the liquid is heated by a vaporiser, producing vapour that is inhaled. Liquids for e-cigarettes consist of carrier substances such as propylene glycol and vegetable glycerin, flavourings, and optionally nicotine. The composition varies depending on the liquid. The nicotine concentration and the concentration of other ingredients in the vapour are decisive for the effect and the risk. There are varying concentrations of harmful substances in the vapour, depending on the liquid and device used. The nicotine content of liquids must be labelled in the EU, however this requirement does not apply to nicotine-free liquids – one example of the uncertainties surrounding ingredients. Disposable cigarettes are a special form of vape that are discarded after a single use.

The Health Check: Is Vaping Really the Less Harmful Alternative?

For most switchers, the health question is the decisive factor. Heating liquids produces, among other things, aldehydes, which are considered harmful to health. The general health risks of vaping are lower than those of smoking, but they are by no means negligible. The vapour from e-cigarettes contains carcinogenic substances that can increase the risk of cancer. Blood vessels and the cardiovascular system are also put under strain by inhaling vapour. The body and various organs can be affected by the absorption of harmful substances. Many users report breathing difficulties after consuming e-cigarettes.

Harmful Substances Compared to Cigarettes

E-cigarettes contain fewer harmful substances than conventional cigarettes, but they are not risk-free. Certain ingredients in the vapour can cause oxidative stress and lead to cell damage. Studies show an increase in certain health problems among e-cigarette users. Lead, zinc, and other metals have been detected in the vapour, and their concentration and concentrations can affect health. Studies involving patients confirm the health effects of vaping.

E-Cigarettes: The Long-Term Effects Are Unknown

A professor of toxicology emphasises the uncertainties regarding long-term effects. Health authorities also regularly reassess the risks of e-cigarettes. The significance of current studies is limited, as long-term data are lacking. Some liquids have been found to contain additives of prohibited substances such as caffeine and vitamins. Additives in liquids can pose additional risks. The tobacco industry is constantly developing new products to serve the market. With tobacco heaters, a piece of tobacco is heated, which differs from vaping. The heating of tobacco and liquids is the central operating principle of both systems. E-cigarettes also contain harmful substances.

About Nicotine

The nicotine concentration and nicotine content determine the addictive effect. Liquids usually consist of propylene glycol, glycerin, flavourings, and water. One example of uncertainty: even nicotine-free liquids can contain unknown ingredients. Young people in particular face health risks from consumption. Anyone who wants to protect their health should stop smoking. E-cigarettes can help with smoking cessation, but are not suitable for everyone. Many users consume both – cigarettes and vapes – which, known as dual use, poses additional risks. Switching completely can improve quality of life. The reason lies in the fundamental difference between the two systems. Both substances place a burden on the lungs.

Combustion vs. Vaporisation: Why Tar and Carbon Monoxide Make the Difference

When smoking a cigarette, a combustion process takes place at over 800 °C. This produces a toxic cocktail of thousands of chemicals. The most harmful of these are tar, which coats the lungs and is considered highly carcinogenic, and carbon monoxide, a respiratory poison that blocks the transport of oxygen in the blood.

An e-cigarette, on the other hand, burns nothing. It heats a liquid – the so-called liquid – to approximately 150–250 °C until an aerosol is produced that you inhale. The liquid is heated in the vaporiser, which generates the vapour. Heating liquids can produce aldehydes, which can be harmful to health. Compared to cigarettes, however, e-cigarettes release fewer harmful substances. The concentration of harmful substances in the vapour is significantly lower, although concentrations can vary depending on the device and liquid. The question of whether there is tar in e-cigarettes can therefore be clearly answered with no.

With tobacco heaters, unlike e-cigarettes, a piece of tobacco is heated rather than a liquid being vaporised. When the tobacco is heated, lead, zinc, and other metals can pass into the vapour alongside other substances.

The Ingredients in the Vapour: An Honest Look at the Risks

The Main Components: 1. Propylene Glycol

Of course, the aerosol from a vape is not pure air either. The main components are propylene glycol and vegetable glycerin (carrier substances for flavour and nicotine), food-grade flavourings, additives, water, and – depending on choice – nicotine. The composition of the liquid is of central importance here. Some liquids have also been found to contain prohibited substances such as caffeine or vitamins as additives, which poses additional risks. It should be noted that e-cigarettes can also contain harmful or carcinogenic substances. The nicotine concentration and nicotine content in the liquid largely determine the addictive effect and should be clearly labelled. One example: with nicotine-free liquids, it is often unclear which ingredients are actually present, which brings with it uncertainties and potential health risks. Although these substances are considered significantly less harmful than the thousands of harmful substances in tobacco smoke, health risks from vaping nonetheless exist. Heating the liquids can produce aldehydes such as formaldehyde, which are considered toxic and potentially carcinogenic. The concentration of harmful substances in the vapour varies depending on the device and liquid and influences the burden placed on the body. Studies also show that metals such as nickel, silver, or aluminium can be detected in the vapour, which are harmful to health. Inhaling the vapour can lead to short-term breathing difficulties such as coughing or irritation. In the long term, the substances absorbed can damage the body and in particular the blood vessels, increasing the risk of cardiovascular disease. These risks are especially relevant for young people, as they are more sensitive to the ingredients and there is a heightened potential for addiction. Simply eliminating the combustion process already represents a massive reduction in risk.

Fewer Harmful Substances, Less Harmful? How Harmful Are Modern E-Hookahs?

In short: we don't fully know.

Over the past two decades, the market surrounding e-cigarettes and e-liquids has evolved considerably – both technically and in terms of composition and usage. Modern liquids contain numerous additives and flavourings that have not yet been examined in long-term studies. Accordingly, no definitive statements can be made today about possible long-term consequences.

In the early years of vaping, the focus was primarily on smoking cessation. The liquids were comparatively simple in composition and mostly consisted of propylene glycol, vegetable glycerin, nicotine, and flavouring. These classic freebase nicotine liquids already delivered a satisfying experience at low nicotine concentrations, as the so-called 'throat hit' was clearly noticeable and effectively curbed cravings.

As the market grew, large brands and tobacco companies increasingly entered the scene. From around the mid-2010s, a new form of nicotine gained traction: nicotine salts. Here, nicotine is chemically bound to an organic acid, which lowers the pH level and makes inhalation significantly smoother – even at higher nicotine concentrations. Modern pod systems such as pre-filled pods and disposable e-cigarettes have been a major driving force behind this development.

As a result, liquids today can offer higher nicotine strengths without causing a strong burning sensation in the throat. This can lead users to reach for their vape more frequently in order to achieve the desired nicotine effect. A higher nicotine concentration can increase the potential for dependency, particularly when the frequency of consumption rises in order to maintain a constant nicotine level. Studies do indicate that nicotine salts can alter nicotine uptake, but the influence on addiction potential is complex and cannot be attributed solely to the form of nicotine.

A further aspect of this development is the ever-growing number of additives, flavourings, and functional chemicals in liquids. Some of these – such as certain cooling agents or flavour carriers – are increasingly attracting the attention of health authorities, as knowledge about their long-term effects when inhaled is limited or is currently still being evaluated.

Overall, it can be noted that today's liquids are technically more advanced and considerably more diverse than before, which offers many consumers a more pleasant vaping experience while also carrying the risk of overdose and increased addiction potential. At the same time, this creates new uncertainties – particularly because reliable long-term studies on many ingredients are lacking.

Long-term consequences in focus: What science knows – and what it doesn't

One thing is clear: the long-term consequences of vaping compared to cigarettes have not yet been conclusively researched, as e-cigarettes have only existed for a relatively short time. Studies involving patients show indications of an increase in certain health problems such as respiratory diseases. A professor of toxicology emphasises that it is primarily the oxidative stress contained in the vapour that can lead to cell damage. Health authorities point out that the significance of current studies is limited and that uncertainties regarding long-term consequences exist. There are indications that carcinogenic substances in the vapour may increase the risk of cancer. The tobacco industry is constantly developing new products such as e-cigarettes and tobacco heaters in order to respond to changing consumer habits.

Quitting smoking is the best way to improve one's health and quality of life. E-cigarettes can help with smoking cessation, but should not be used on a permanent basis.

Anyone who consumes both (cigarettes and vapes) exposes themselves to the risks of so-called dual use.

Non-smokers should under no circumstances start vaping, as inhaling aerosols and particularly nicotine is associated with health risks and offers no health benefit. Even though e-cigarettes release fewer harmful substances compared to tobacco smoke, they are not harmless and can, among other things, affect the airways, the cardiovascular system, and nicotine dependency.

For smokers, however, vaping can represent a pragmatic form of harm reduction, as switching eliminates the combustion process and thereby significantly reduces the uptake of many highly toxic substances. Many switchers report a noticeable improvement in their quality of life in this context. Nevertheless, the long-term goal here should also be the complete cessation of nicotine use.

Addiction potential compared: Is vaping just as addictive as smoking?

The primary addiction potential in both cigarettes and vapes comes from nicotine. The nicotine concentration and nicotine content are decisive for the addictive effect, as they determine how quickly and how much nicotine is absorbed by the body. In this respect, vaping with nicotine is just as addictive as smoking. The concentration and concentrations of nicotine can vary greatly depending on the product, which makes it difficult to compare the risk of addiction.

The advantage of vapes

The decisive advantage of the e-cigarette lies in control. Whereas with a cigarette you absorb a fixed dose of nicotine, with liquids you can determine the nicotine strength yourself and reduce it gradually. Many former smokers use this as part of smoking cessation to slowly phase out their dependency and achieve a lasting quit. Nevertheless, from a health perspective it is best to quit smoking and to forgo both cigarettes and vapes, in order to avoid all health risks.

Avoid dual use!

Anyone who consumes both – that is, cigarettes and vapes – exposes themselves to the additional risks of so-called dual use. Young people in particular face an elevated risk, as the products appear attractive to them and carry both health and legal dangers. In general, the health risks of vaping should not be underestimated, as various studies point to harmful effects on the lungs, the cardiovascular system, and other organs.

The big cost comparison: How much money you really save

The cost comparison between vaping and smoking comes out clearly in favour of the e-cigarette. Whilst cigarettes may appear cheaper at first glance, they are more expensive in the long run than reusable devices, as they must be disposed of after a single use. The wide range of vapes and liquids offers suitable options for every taste and every budget. There are numerous models with different technical specifications, which is also reflected in the differences in price.

The battery as a cost factor

The battery in particular plays an important role in the cost and lifespan of devices, as high-quality batteries can extend the period of use. Modern devices are often equipped with a microprocessor that improves temperature control and thereby influences the price. Through its product development and pricing strategies, the tobacco industry plays a significant role in shaping the range and cost structure in the e-cigarette sector. Whilst you do have to invest in a device initially, the ongoing costs for liquids and consumable parts (coils) are considerably lower.

Example calculation: A smoker saves real money

• Smoker: One pack per day (approx. €9) = €270 per month (example).
• Vaper: After purchasing a starter kit (approx. £30–50), the monthly costs for liquids and coils average £30–60.
• Your monthly savings could therefore be around £200 or more!

Environment and Society: How Sustainable Is the Switch Really?

Switching to e-cigarettes is often presented as a modern and more sustainable step compared to traditional smoking. But what does the environmental impact and social acceptance actually look like? Anyone choosing e-cigarettes should keep not only the health effects in mind, but also the ecological and social consequences. Both resource consumption and the public image of vapers and smokers are playing an ever-greater role in the current debate around e-cigarette use.

Waste, Recycling and Resource Consumption Compared

At first glance, e-cigarettes score points for producing less waste: unlike filter cigarettes, where millions of cigarette butts are carelessly discarded every day, many e-cigarette models are rechargeable and long-lasting. This saves packaging material and reduces classic cigarette waste. However, vaping has its downsides too: disposable vapes and disposable e-cigarettes in particular are generating growing volumes of electronic waste, as they are discarded after brief use and are rarely recycled properly. The Federal Centre for Health Education points out that responsible handling of e-cigarettes and vapes is crucial – both when choosing sustainable models and when disposing of them. Those who opt for reusable devices and liquids, and pay attention to environmentally conscious manufacturers when buying, can significantly reduce the ecological footprint of their e-cigarette use. Nevertheless, the challenge remains that the production of batteries, atomisers and liquids also consumes resources such as metals and plastics. Mindful use and proper disposal are therefore an important contribution to environmental protection.

Side note: When it comes to tobacco consumption, it is primarily filter cigarettes that pose an environmental problem. Smokers who use roll-your-own tobacco without filters, or pipe smokers, represent a significantly smaller problem for the environment than filter cigarettes carelessly discarded into nature.

Social Acceptance: How Are Vapers and Smokers Perceived?

The social perception of e-cigarettes and traditional smoking is changing. While smokers are increasingly met with disapproval in many areas of society, vaping is seen by some as a less harmful and more modern alternative.

And it is precisely at this point that a problem arises, as several consumer protection organisations criticise the fact that marketing and product design (e.g. colourful designs, sweet flavourings such as vanilla, fruits and other appealing flavours, as well as social media presence) can be particularly appealing to young people – and accuse parts of the industry of deliberately accepting these effects.

The Federal Centre for Health Education and numerous health authorities warn of the health risks of e-cigarette use, particularly for young people and pregnant women.

The addictive potential of nicotine remains high even with e-cigarettes, which is viewed critically especially among young people. Experts such as Prof. Dr Heino Stöver from the University of Applied Sciences emphasise the importance of education and regulation to protect consumers and prevent misuse.

At the same time, many see the e-cigarette as an opportunity for smokers to quit tobacco use and thereby reduce the risk of cardiovascular disease, COPD and other related conditions. Social acceptance therefore depends strongly on responsible use, the choice of product and the individual's situation. One thing is clear: anyone who chooses e-cigarettes should be aware of the health risks and addictive potential, and should regularly keep up to date with new findings and recommendations.

Your Practical Guide to a Successful Switch

Switching from cigarettes to vaping can feel overwhelming at first. The wide range of e-cigarettes, liquids and accessories offers the right choice for every taste and need. There are numerous models that are particularly suited to switchers and offer different technical specifications. Modern devices often feature a powerful battery that ensures reliable use. In advanced models, a microprocessor provides precise temperature control and optimised functionality. The variety of flavours – such as chewing gum, for example – makes the switch particularly appealing for many people.

Side Effects When Switching

However, breathing difficulties can also occur during the transition phase, as the airways need to adjust to the new substances. Many report that their quality of life has improved as a result of switching. E-cigarettes can be a support tool for smoking cessation, but the goal should always be to quit smoking altogether. Anyone using both – that is, cigarettes and vapes – continues to expose themselves to health risks. Young people in particular face an elevated risk, as the products can appear attractive due to sweet flavours and technical innovations. But don't worry – with the right steps, it is achievable.

Step 1: Finding the Right Device for You

For beginners, we recommend a so-called pod system. These devices are small, easy to use and best simulate the draw of a cigarette. There are various models that differ in their technical specifications, such as temperature control and ease of use. Our range includes a wide selection of liquids as well as Open Pod Systems and Pre-Filled Pod Systems along with further accessories, so there is a suitable device for every need. The battery plays a central role in these devices, as it significantly influences their reliability and handling. In modern devices, an integrated microprocessor ensures precise control of the heating elements and improved temperature control. They are the ideal e-cigarette starter kit for heavy smokers. Don't be put off by complex professional devices – simplicity is what counts at the start.

Step 2: Choosing the Right Nicotine Strength

The right nicotine strength is crucial to avoid withdrawal symptoms. A useful rule of thumb:

• Heavy smokers (1 pack or more per day): Start with 12 mg/ml or even 18 mg/ml.
• Regular smokers (up to 1 pack per day): 6 to 12 mg/ml is often appropriate.
• Light smokers: 3 to 6 mg/ml should be sufficient.

The choice of the appropriate nicotine strength depends on the individual nicotine content and the nicotine concentration in the liquid, as these determine how much nicotine is actually absorbed. Liquids are available in various concentrations, and the nicotine concentration can vary considerably depending on the product, which directly affects the effect and consumption.

Viele Umsteiger, die sich fragen, welche Vape wie eine Zigarette schmeckt, greifen zu Beginn zu Tabak-Liquids, um den Übergang zu erleichtern.

Erfahrungen von Umsteigern: Das erwartet dich in der ersten Woche

“Am Anfang fehlte mir das Ritual des Anzündens. Aber schon nach drei Tagen war mein Raucherhusten fast weg und ich konnte wieder besser riechen. Das hat mich motiviert, dabeizubleiben.” – Markus, 42

In der Umstiegsphase können jedoch vorübergehend Atembeschwerden wie Husten oder Reizungen auftreten, da sich die Atemwege an die neue Situation anpassen. Viele berichten, dass sich ihre Lebensqualität durch den Verzicht auf Tabakprodukte und das bewusste Leben ohne Rauch deutlich verbessert hat. E-Zigaretten können beim Prozess der Raucherentwöhnung unterstützen, indem sie eine Alternative bieten. Dennoch sollte das Ziel immer sein, vollständig mit dem Rauchen aufzuhören, um die Gesundheitsrisiken zu minimieren. Wer beides – also Zigaretten und E-Zigaretten – parallel nutzt, setzt sich weiterhin gesundheitlichen Risiken des sogenannten Dual Use aus. Besonders für Jugendlichen besteht ein erhöhtes Risiko, da sie durch die Attraktivität der Produkte und mögliche gesundheitliche Folgen besonders gefährdet sind.

Fazit: Eine informierte und persönliche Entscheidung treffen

Der Vergleich Dampfen vs. Rauchen zeigt klar: Ein Umstieg auf die E-Zigarette ist keine risikofreie, aber eine risikoreduzierende Entscheidung. E-Zigaretten setzen im Vergleich zu herkömmlichen Zigaretten weniger Schadstoffe frei, bergen jedoch weiterhin Gesundheitsrisiken, insbesondere für Lunge und Herz-Kreislauf-System. Es ist eine pragmatische Zigaretten-Alternative für all jene, die den kompletten Rauchstopp (noch) nicht schaffen. E-Zigaretten können beim Prozess der Raucherentwöhnung unterstützen, sollten aber nicht dauerhaft als Ersatz dienen. Die gleichzeitige Nutzung von beiden – also Zigaretten und E-Zigaretten (Dual Use) – kann die Risiken sogar erhöhen und ist daher nicht zu empfehlen. Letztlich ist es für ein gesünderes Leben am besten, ganz mit dem Rauchen aufzuhören, um die Gesundheit nachhaltig zu fördern. Du reduzierst die Aufnahme von tausenden Giftstoffen massiv, sparst eine erhebliche Menge Geld und gewinnst Lebensqualität zurück.

Die Entscheidung liegt bei dir. Dieser Guide soll dir helfen, sie informiert und selbstbestimmt zu treffen.
