Our findings to date

What is our science telling us? Studies on our tobacco heating system are well advanced, and the results are encouraging.
Scientists in laboratory

Our studies on our most advanced smoke-free alternative product, the Tobacco Heating System (THS)1, are progressing rapidly. They support the following findings (when used as intended):

  • According to indoor air quality tests, the THS aerosol does not adversely affect indoor air quality. The THS is also not a source of second-hand smoke.

The totality of our studies to date indicates that the THS, while not risk-free, is likely to present less risk of harm compared to continued smoking for adult smokers who switch to it completely. 

1 The THS is marketed as IQOS

Results to date give us confidence that we are on course with our plans to demonstrate that THS is a less harmful alternative for adult smokers who switch completely.

What steps are we taking to independently verify our scientific data?

We are committed to seeking independent verification of the scientific data we have generated on our RRPs.* This includes:

  • Publishing over 365 peer-reviewed publications and book chapters related to our smoke-free products since 2008
  • Conducting an in-depth analysis of study reports by independent experts
  • Developed the sbv IMPROVER.com platform. sbv IMPROVER stands for Systems Biology Verification combined with Industrial Methodology for Process Verification in Research. It is a methodology applied through crowd-sourcing, which enables the verification of research methods and study results.

* Reduced Risk Products (“RRPs”) is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking.  PMI has a range of RRPs in various stages of development, scientific assessment, and commercialization. Our RRPs are smoke-free products that produce an aerosol that contains far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
