The science and vision behind IQOS.

IQOS has gone through robust scientific assessments, including, to-date, 18 non-clinical and 10 clinical studies involving thousands of participants.

The totality of evidence available shows that, while IQOS use is not risk-free, switching completely to IQOS presents less risk to your health than continuing to smoke cigarettes.

Technology – the world revolves around it. Over the years, it has radically changed our lives for the better. The way we work, the way we communicate, the way we travel. By combining science and technology is how we developed a better alternative to continued smoking. IQOS is changing for the better the way adult smokers, who would otherwise continue to smoke, can enjoy tobacco.

IQOS heats tobacco instead of burning it for a simple reason: the burning of tobacco emits high amounts of harmful chemicals like carbon monoxide.

IQOS ILUMA SMARTCORE INDUCTION™ technology and IQOS HeatControl™ technology prevent tobacco from burning, which means they significantly reduce the number and level of harmful chemicals emitted compared to cigarette smoke.

Cigarettes burn tobacco, reaching high temperatures, and producing ash, tar, and smoke with high number and levels of harmful chemicals. Cigarette smoke is a complex mixture of over 6000 chemical substances, around 100 of which have been linked to smoking-related diseases by public health authorities.

IQOS ILUMA SMARTCORE INDUCTION SYSTEM™ technology and IQOS HeatControl™ technology heat tobacco to a lower temperature, ensuring that combustion does not occur. Because there is no combustion, IQOS does not produce smoke. It generates a tobacco vapour that brings you a high-quality tobacco taste experience with 95% less* harmful chemicals compared to cigarettes.

Indoor Air Quality (“IAQ”) refers to the air quality inside buildings, generally based on the principle of ensuring the health and comfort of the occupants. Temperature, humidity and contaminants are some of the factors that can affect the indoor air quality. But, human presence and activities such as cooking, cleaning or smoking have been proven to have considerable impact.

To enhance our knowledge and understanding the impact of IQOS on indoor air quality we conducted studies simulating “real-world” conditions in an environmentally controlled room. Our testing methods are validated, and ISO accredited.

Our study shows that, because IQOS does not burn tobacco and it does not generate smoke and it drastically reduces levels of harmful chemicals like carbon monoxide, it does not negatively impact indoor air quality. This means that the few compounds we nevertheless detected were found at very low concentrations and far below the maximum exposure levels defined in existing air quality guidelines.

Our studies show that the satisfaction of those who switched completely to IQOS is comparable to that of those who continued to smoke cigarettes.* Discover more about our scientific assessment journey.
