IQOS heats tobacco instead of burning it for a simple reason: the burning of tobacco emits high amounts of harmful chemicals. IQOS HeatControl™ Technology prevents tobacco from burning, which means it significantly reduces the number and level of harmful chemicals emitted compared to cigarette smoke.

Tobacco vapor vs Smoke

IQOS tobacco vapor is less harmful than cigarette smoke. To demonstrate this, we conducted a comprehensive assessment program that included 10 clinical studies on aerosol chemistry (as well as data from 18 non-clinical studies), and involved thousands of participants in the US, Japan, UK and Poland. Evidence demonstrates that switching completely to IQOS, while not risk-free, presents less risk of harm compared with continuing to smoke cigarettes.

Did you know we’ve created a machine to show the significant differences between smoke produced by burning tobacco in a cigarette compared to the tobacco vapor generated when tobacco is heated in IQOS?

Our studies show that the satisfaction of those who switched completely to IQOS is comparable to that of those who continued to smoke cigarettes*. Discover more about our scientific assessment journey.
