This website contains information about our smoke-free products and we need your age to make sure that you are an adult in Lebanon who would otherwise continue to smoke or use nicotine products. Our nicotine and tobacco products are not an alternative to quitting and are not designed as cessation aids. They are not risk free. They contain nicotine, which is addictive. Only for use by adults.

IQOS research

The science and the research behind IQOS.

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 harmful, 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 vapour 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 harmful 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.

Cigarettes expose others to smoke – IQOS ILUMA doesn't.
IQOS ILUMA doesn’t produce smoke or second-hand smoke.
It produces a tobacco vapor that contains significantly less harmful chemicals*, resulting in less impact on the air around you and others compared to cigarette smoke.

IMPORTANT INFORMATION: IQOS ILUMA is not risk-free for you or others around you.

* Reductions in levels of the 9 harmful chemicals the World Health Organization recommends to reduce in cigarette smoke, which do not include nicotine. See Important Information on IQOS.com

Clinical studies.

Do the significantly lower number and levels of chemicals in IQOS tobacco vapour also mean lower levels of such chemicals in the body? If you reduce the level of harmful chemicals in IQOS tobacco vapour, it would make sense that switching completely to IQOS from cigarettes reduces exposure to these harmful chemicals. To prove this, we measured biomarkers of exposure for a number of these harmful chemicals in thousands of smokers who participated in our clinical study programme (some switched to IQOS, while others either continued smoking their cigarette brand or quit for the duration of the study).

These studies show that when smokers switch to IQOS, their body absorbs significantly lower levels of harmful chemicals, which in turn results in favourable changes in a number of risk markers selected because of their known association with smoking-related diseases. But it doesn't end there.

IQOS satisfaction.

Our clinical study participants who switched to IQOS also report that IQOS provides cigarette-like satisfaction.* This supports our view that IQOS has the potential to be an acceptable alternative for adult smokers who would otherwise continue to smoke. Based on all the scientific evidence, we are confident that switching completely to IQOS ILUMA is less harmful than continuing to smoke.**

The absolute best choice remains to quit tobacco and nicotine use altogether. IQOS is not an alternative to cessation. It delivers nicotine, which is addictive.

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

Long-term studies.

Once IQOS is available in the market, the research moves from being conducted in a pre-market setting to a real-world post-market setting. There, we look at how the product is being used and by whom in order to complement our pre-market findings and to do our best to identify and prevent use or uptake by unintended audiences. After years of commercialization in many countries, the available data confirms our pre-market observations, in particular in terms of IQOS’ appeal to adult smokers and the relative lack of interest in former and never smokers.

We also monitor reports of health effects now that the product is used by millions of adult users. Long-term studies will eventually help us to evaluate the potential disease–specific risk reduction of IQOS. Gathering data to answer this question takes time, but it’s the right choice. So far, all the data we’ve seen points in the right direction.

The result.

IQOS is a better choice than continued smoking. The totality of scientific evidence available to-date clearly demonstrates that Switching completely to IQOS ILUMA presents less risk to your health than continuing to smoke.*
