The science and vision behind IQOS
IQOS is the combination of science, technology and vision.
We believe in science. We believe it can change the lives of millions of smokers, who would otherwise continue to smoke. To this effect, we recruited scientists to work on an important idea: developing less harmful products that cigarette smokers can switch to if they don’t quit. Hundreds of scientists and engineers at PMI’s global Research and Development centers in Switzerland and Singapore have developed and evaluated IQOS, an innovative electronic device that heats and not burns tobacco. It produces a tobacco vapor that delivers tobacco taste and nicotine.
Tested to the highest standards
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 is a better alternative than continuing to smoke cigarettes.

Why heating is better
We developed a better alternative to continued smoking by combining science and technology. IQOS changes the way of using tobacco for adult smokers, who would otherwise continue to smoke.
IQOS heats tobacco instead of burning it for a simple reason: the burning of tobacco emits high amounts of harmful chemicals. IQOS HeatControl™ Technology prevents tobacco from burning, which means it significantly reduces the number and level of harmful chemicals emitted compared to cigarette smoke.
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 6000 chemical substances, around 100 of which have been linked to smoking-related diseases by public health authorities.
Tobacco vapour vs smoke
IQOS tobacco vapor is less harmful than cigarette smoke. To demonstrate this, we conducted a comprehensive assessment program that included 10 clinical studies on aerosol chemistry (as well as data from 18 non-clinical studies), and involved thousands of participants in the US, Japan, UK and Poland. Evidence demonstrates that switching completely to IQOS, while not risk-free, is a better alternative to continuing to smoke cigarettes.
