The science and vision behind IQOS.
IQOS is the combination of science, technology and vision.
Science behind heated tobacco
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 vapour 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 presents less risk to your health than continuing to smoke cigarettes.

Why heating is better
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 HeatControl™ Technology prevents tobacco from burning, which means it significantly reduces the number and level of harmful chemicals emitted compared to cigarette smoke.
Cigarettes produce tar, IQOS doesn’t
“Tar” is the residue from smoke after a cigarette has burned. IQOS does not produce tar because it heats tobacco instead of burning it. It generates an aerosol residue that is fundamentally different from “Tar” and consists of significantly lower levels of harmful chemicals.
IMPORTANT INFORMATION: Although IQOS does not produce tar, IQOS is not risk free, and delivers nicotine which is addictive.
*Average reductions in the levels of a range of harmful chemicals (excluding nicotine) compared to cigarette smoke.
Tobacco vapour vs smoke.
IQOS tobacco vapour is less harmful than cigarette smoke. To demonstrate this, we conducted a comprehensive assessment programme 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, presents less risk of harm compared with continuing to smoke cigarettes.
IQOS emits less harmful chemicals than cigarettes
Cigarettes burn tobacco, which produces high amounts of carbon monoxide. IQOS doesn’t burn tobacco, producing on average 98% less carbon monoxide (CO) and significantly lower levels of other harmful chemicals compared to cigarettes.*
IMPORTANT INFORMATION: This does not mean a 98% reduction in risk. IQOS is not risk-free, and delivers nicotine which is addictive.
*Source: We measured the levels of certain harmful chemicals prioritised for reporting by renowned public health organisations, and these are reduced on average by 95% compared to the smoke of a cigarette (nicotine excluded).
Science machine.
Did you know we’ve created a machine to show the significant differences between smoke produced by burning tobacco in a cigarette compared with the tobacco vapour generated when tobacco is heated in IQOS? Watch the science machine video to see more.
Switching to IQOS.
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.
IQOS is not risk-free and delivers nicotine, which is addictive. The best decision any smoker can make is to quit tobacco and nicotine use altogether.
