Tobacco vapour vs smoke.

IQOS tobacco vapour is less harmful than cigarette smoke. To demonstrate this, we conducted a comprehensive assessment programme 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.
