The science and vision behind IQOS.

IQOS is the combination of science, technology and vision. 

PMI building in Switzerland

Science behind heated tobacco

Philip Morris International (“PMI”) believes in science. PMI believes it can change the lives of millions of adult smokers, who would otherwise continue to smoke. To this effect, PMI has recruited scientists to work on an important idea: developing better alternatives to cigarettes that adult 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 does not burn tobacco. It produces a tobacco vapor that delivers real tobacco taste.

 

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

 

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 choice than continuing to smoke.*

Why heating is better than burning.

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, PMI developed a better alternative to continued smoking. 

IQOS is changing for the better the way adult smokers, who would otherwise continue to smoke, can experience tobacco. 

IQOS is a better choice than continued smoking for the simple reason: IQOS heats tobacco instead of burning it. IQOS HeatControl™ Technology prevents tobacco from burning, which means it significantly reduces the number and level of harmful chemicals emitted compared to cigarette smoke.*

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

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 does not produce smoke. It generates a tobacco vapor that brings you a high-quality tobacco taste experience with 95% less harmful chemicals compared to cigarettes. *

IMPORTANT INFORMATION: It does not necessarily equal a 95% reduction in risk. IQOS is not risk-free. 

* “95% less” represents the average reductions in levels of a range of harmful chemicals (excluding nicotine) compared to the smoke of a reference cigarette. See Important Information

Burning a cigarette generates smoke and tar. This is not the case with IQOS. Why?

IQOS heats tobacco instead of burning it. It generates a tobacco vapor that is fundamentally different from cigarette smoke and which contains significantly less harmful chemicals.*

Important information: The absence of tar does not mean that IQOS is risk free.

Tobacco vapor vs cigarette smoke.

Tobacco vapor generated by using IQOS is fundamentally different from cigarette smoke. To demonstrate this, PMI 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, is a better choice than continuing to smoke. 

Important Information: IQOS is not risk-free and provides nicotine, which is addictive.

IQOS doesn't burn tobacco

IQOS heats tobacco instead of burning it, so it doesn't produce fire, ash or smoke. This makes IQOS a better choice compared to continued smoking.

Important information: IQOS is not risk-free.

Did you know that Philip Morris International has created a machine to show the significant differences between smoke produced by burning tobacco in a cigarette compared to the tobacco vapor generated when tobacco is heated in IQOS? Watch the science machine video to see more.

Switching to IQOS.

PMI’s studies show that the tobacco satisfaction of those who switched completely to IQOS is comparable to that of those who continued to smoke cigarettes*.

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.
