Vaping vs Smoking: The Facts, Level-Headed

Plenty of half-truths circulate around e-cigarettes, in both directions. Some talk vaping up, others equate it with smoking. Neither helps anyone see clearly. Here we set out the key points factually, without selling you anything we can't back up.

Let's be clear up front: vaping is not risk-free. It's an option for adult smokers who already consume nicotine. Anyone who has never smoked should not start, and non-smokers least of all.

The central technical difference: combustion

A cigarette is lit and smoulders at several hundred degrees. Burning tobacco produces tar and a host of other substances that the smoke carries into the lungs. That is the core of the problem with smoking, not nicotine on its own.

An e-cigarette burns nothing. A coil heats the liquid until it vaporises. No smouldering, no tar, no smoke in the classic sense, but aerosol. That doesn't mean this aerosol is harmless. It only means the mechanism is a different one. How exactly it works is set out in the guide to the e-cigarette.

What the authorities say

Health authorities in several countries classify e-cigarettes as less harmful than tobacco cigarettes, but consistently stress two things: less harmful does not mean harmless, and the benefit applies only to people who already smoke and switch over completely. For non-smokers and young people the same bodies clearly advise against it.

This assessment is no free pass. Long-term data on e-cigarettes is thinner than for smoking, because the products have only been widespread for a good decade and a half. Anyone who values caution keeps that in mind.

Nicotine is in both

Cigarette or vape: the nicotine stays. Nicotine is highly addictive and is not harmless. An e-cigarette at 20 mg/ml (the legal maximum in Switzerland) delivers enough nicotine to curb the craving, with the same addictive effect as a cigarette. The difference lies not in the addictive substance, but in the surrounding combustion products.

Anyone who also wants to get off nicotine can lower the strength step by step. More on that in the nicotine strengths guide and under Nicotine-free vapes.

What matters when switching

Practice shows: half measures achieve little. Anyone who vapes in the morning and smokes again in the evening gets barely anything out of it. What is decisive is the complete switch, and for that you need a device that delivers enough nicotine and doesn't feel like a compromise. For most people making the switch, a pod system works well, because the way it draws feels close to a cigarette.

The full process, from choosing the device to the right strength, we have put together separately: Vaping instead of smoking, the switch step by step.

And how does the cost compare?

A point that's often underestimated: over the course of a year, vaping usually comes in well below what a pack a day costs, especially with refillable systems rather than disposable vapes. The concrete figures for Switzerland can be found under What does vaping cost.

In short

• Combustion is the main difference: the cigarette burns tobacco (tar, smoke), the e-cigarette vaporises liquid (aerosol).
• Authorities classify vaping as less harmful, but expressly not as harmless, and only as an alternative for smokers.
• Nicotine stays in both and is highly addictive. The addictive substance is the same.
• For the switch to bring any benefit, it has to be complete.

As of March 2026. Nicotine (in many products up to 20 mg/ml) is highly addictive. For adults aged 18 and over only. Anyone who does not smoke should not take up vaping either. Not medical advice.
