IQOS clinical studies

We continue informing you about what we know about IQOS. This time you will learn more about our extensive scientific assessment, including clinical studies, which show that switching completely to IQOS is likely to present less risk to your health.

The development of innovative tobacco heating devices has taken more than 20 years of research and development, and required an investment in this new technology and research which has already reached 4.5 billion US dollars.

The data & results from our scientific studies are the basis of all our messages.

We have 10 clinical studies, conducted in Europe, Japan and the USA, which now includes a study with 6 months of follow-up, looking at favorable changes in smoker who switch to IQOS compared to those who continue to smoke cigarettes. In addition, we supporting evidence on the potential for risk reduction from the 18 non-clinical studies that vary in size and duration – from a few days to up to 18 months.

Based on the totality of the scientific evidence to date, switching completely to IQOS is likely to present less harm to your health than continuing to smoke.

PMI publishes its research on tobacco harm reduction and our smoke-free products in peer-reviewed scientific journals. Our scientific research on IQOS is published using the scientific product description “Tobacco Heating System” or “THS”.

Important information: this does not mean IQOS is risk free.
