The science and vision behind IQOS

IQOS is the combination between science, technology and vision

Science

We believe our science can change the lives of millions of adult smokers, who would otherwise continue to smoke.

To this effect, we have had the best scientists to work towards one goal: creating an alternative to cigarettes for those adult smokers who want a better choice than continuing to smoke cigarettes. Hundreds of scientists and engineers at PMI's global Research and Development centers in Switzerland and Singapore have developed and tested IQOS, an innovative electronic device that heats and not burns tobacco.

Important information: IQOS is not risk-free. It delivers nicotine, which is addictive.

 

* Average reductions in levels of a range of harmful chemicals (excluding nicotine) compared to the smoke of a reference cigarette (3R4F). It does not necessarily equal a 95% reduction in risk.

Tested to the highest standards

IQOS has undergone robust scientific assessments, including, to date, 18 non-clinical and 10 clinical studies involving thousands of participants. The totality of evidence available shows that switching completely to IQOS is less harmful than continuing to smoke. IQOS emits on average 95% lower levels of harmful chemicals compared to cigarettes.*

Why is heating better

Technology allows us to evolve. 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, we have developed a better alternative to cigarettes.

IQOS heats tobacco instead of burning it for a simple reason: burning tobacco releases the big majority of harmful chemicals in the cigarette smoke causing smoking-related diseases. 

Thanks to its HeatControl™ Technology, IQOS prevents tobacco from burning, and thus, does not produce smoke.

Heating technology

When a cigarette is lit, the tobacco burns at temperatures of around 600°C. This burning process generates smoke and ash; when a smoker takes a puff, the temperature rises above 800°C at the burning tip. 
Cigarette smoke is a complex mixture of over 6,000 chemical substances, around 100 of which have been linked to smoking-related diseases by public health authorities.

IQOS HeatControl™ Technology heats tobacco to a lower temperature (less than 350°C), ensuring that combustion does not occur. Because there is no combustion, IQOS doesn’t produce smoke, it generates a tobacco vapor.

Switching to IQOS

Over 10 million adult smokers in the world have stopped burning tobacco and started heating it with IQOS*.
