Our scientific assessment journey.

Scientific programme.

We have developed a comprehensive step-by-step scientific assessment programme. This programme is inspired by the practices of the pharmaceutical industry and is in line with the USA’s Federal Drug Administration’s 2012 guidance on the assessment of candidate Modified Risk Tobacco products. Our assessment was also conducted according to international standards.

Is IQOS less toxic?

In laboratory settings, we found that IQOS’ tobacco vapour is less toxic than cigarette smoke. Our scientists test our products thoroughly before they go into adult smokers’ hands. Using in vitro assays in our labs, we assessed the cytotoxicity and genotoxicity of IQOS tobacco vapor in comparison with the smoke of a reference cigarette designed for research purposes. Taken together, the results of these assays show that IQOS tobacco vapour is significantly less toxic than the smoke from reference cigarette.

This is just a glimpse of our work. These tests were crucial before we moved on to test IQOS with thousands of adult smokers who voluntarily participated in our clinical study programme and ultimately allowed us to commercialize our products.
