HEAT OR BURN: WHY IQOS?

Why IQOS is a better alternative to continued smoking?

More than 12.7 million adult smokers have quitted burning tobacco and started heating it with IQOS.1 In this article we will talk about the features of IQOS as a tobacco heating system and explain why heating is the basis of this system. How is it different from burning? How is the process of using IQOS different from smoking a cigarette?


Difference 1. Heating vs Burning

Before answering these questions, it's worth noticing that tobacco at the tip of cigarettes burns at temperatures over 800°C, producing a large amount of harmful chemicals contained in smoke.

In contrast, IQOS heats tobacco to a much lower temperature (350°C). Hence the differences between cigarettes and this particular tobacco heating system.


Difference 2. Cigarettes produce tar – IQOS doesn’t

IQOS does not produce tar2, because it heats the tobacco instead of burning it by delivering nicotine, the true taste and satisfaction of real tobacco. Meanwhile, the main cause of smoking-related issues is not nicotine, but the burning process and tar.

Tar is the residue from smoke after a cigarette is burned. Contrary to cigarettes, IQOS produces aerosol residue that is fundamentally different from tar and consists of significantly lower levels of harmful chemicals.


Difference 3. IQOS emits 95% less harmful chemicals compared to cigarettes3

If you search, you will find a number of scientific papers, as well as more than 160 pieces of independent clinical research on your device. Most of them confirmed that IQOS aerosol contains significantly less harmful substances than cigarette smoke.

IQOS tobacco aerosol contains on average 95% less harmful chemicals.3 Our evidence also shows that switching completely to IQOS presents less risk to your health than continuing to smoke.


Difference 4. Cigarettes produce high amounts of carbon monoxide, IQOS doesn’t

Carbon monoxide (CO) is a toxic gas that is produced as a result of burning organic matter, in particular while burning a cigarette.

СCigarettes produce high amounts of carbon monoxide, IQOS doesn’t. IQOS heats tobacco, producing on average 98% less carbon monoxide (CO) and significantly lower levels of other harmful chemicals compared to cigarettes.4


Difference 5. IQOS is backed up by science

For example, did you know that IQOS is the first and yet only tobacco heating system was recognized by the US Food and Drug Administration (FDA) as Modified Risk Tobacco Product?

The USA FDA has concluded that switching completely from cigarettes to IQOS reduces your body’s exposure to harmful or potentially harmful chemicals.5


Difference 6. IQOS is racing towards smoke-free future

Over 400 scientists and engineers at the PMI R&D Center in Switzerland have been developing and testing IQOS for 12 years, moving towards a new smoke-free future.

More than $ 8.1 billion has been spent as a result of this work. The company's vision is that one day the smoke-free products will completely replace cigarettes.


Difference 7. IQOS has a number of advantages in daily life

You already know that, unlike cigarettes, IQOS does not burn tobacco and, therefore, does not produce smoke and ash. With this advantage, many of our customers have noticed that:

  • IQOS leaves less odor on hands, hair and clothes than cigarettes.
  • IQOS has no negative impact on indoor air quality.
  • Due to the lack of second-hand smoke, using IQOS is less likely to disturb others nearby.

Smokers that have switched to IQOS have also noticed a number of personal hygiene benefits:

  • Their breath is fresher than when they smoke cigarettes.
  • There’s less unpleasant feeling and aftertaste left in their mouth compared to after finishing smoking a cigarette.
  • IQOS leaves less stains on their fingertips and teeth than cigarettes do.6


Every day, thousands of adult smokers around the world stop smoking and start heating tobacco with IQOS. Completely switching to IQOS is a better alternative to your health than continuing to smoke.7
