IQOS science and vision.

IQOS is the combination of science, technology and vision. ​

Science

We believe in science. We believe that it can change the lives of millions of smokers who would otherwise continue smoking. For this purpose, we hired scientists who started working on an important mission – the development of less harmful products. Hundreds of scientists at research and development centers in Switzerland and Singapore jointly developed IQOS, an innovative electronic device that heats, not burns, tobacco.

This product is not without risk, it releases nicotine which is addictive. For adults only.

Tested to the highest standards.​

IQOS has been part of extensive scientific evaluations, including 18 non-clinical and 10 clinical studies conducted on thousands of participants. The evidence shows that although IQOS is not a risk-free product, switching to IQOS poses a lower risk than continuing to smoke cigarettes.

Why is heating better than burning?

Technology – something around which the whole world revolves. By combining science and technology, we have developed a better alternative to smoking. IQOS enables all adult smokers to make a change and make better choices. Heating the tobacco, rather than burning it, may seem like a small change - but it redefines the entire tobacco product experience. SMARTCORE INDUCTION SYSTEM™ technology and IQOS HeatControl™ technology prevent combustion, which means they significantly reduce the level of harmful compounds emitted compared to cigarette smoke.

Heating technology

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.

Important information: 95% less harmful substances does not necessarily mean 95% reduction of risk. IQOS is not without risk.
* "95% less" represents an average reduction in the level of a number of harmful substances (nicotine excluded) compared to the smoke of the reference cigarette (3R4F). See Important information on IQOS.com

cigarettes contain tar, iqos does not

Cigarettes produce tar. IQOS doesn't.

Tar is a product of cigarette burning. IQOS does not produce tar because it heats the tobacco instead of burning it. It produces aerosols that are fundamentally different from tar and contain significantly lower levels of harmful substances*.

Switching to IQOS completely is less harmful than continuing to smoke cigarettes**.
This product is not without risk, it releases nicotine which is addictive.
*Average reductions in the levels of a range of harmful substances (excluding nicotine) compared to cigarette smoke.​
**Source: Based on total evidence available for IQOS compared to continued smoking.

Aerosol versus cigarette smoke

The aerosol released when using IQOS is less harmful than cigarette smoke. To confirm this, we created a comprehensive program that included 10 clinical studies of aerosol chemistry involving thousands of users from America, Japan, Britain and Poland. Evidence supports that completely switching to IQOS poses a lower risk than continuing to smoke.
cigarettes burn tobacco, iqos does not

Cigarettes burn the tobacco. IQOS doesn't.

IQOS releases less harmful substances than cigarettes. Cigarettes burn tobacco, producing large amounts of carbon monoxide. Cigarettes burn tobacco, which produces large amounts of carbon monoxide. IQOS does not burn tobacco, so it produces 98% less carbon monoxide (CO) and significantly lower levels of substances that cause long-term harm compared to cigarettes.
Important information: This product is not without risk, it releases 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).

Scientific studies

Our studies have shown that fully converted IQOS users feel a difference from when they were smokers*.
