Philip Morris International’s Tobacco Heating System (THS) does not burn tobacco.

Our scientific studies indicate that the THS, although not risk-free, has the potential to present less risk of harm compared to continued smoking for adult smokers who switch to it completely. 

When used as intended, the THS does not generate combustion or smoke. According to laboratory tests, its aerosol also has significantly lower levels of harmful and potentially harmful constituents (HPHCs) and is much less toxic than cigarette smoke. 

Our research shows negligible interest in the THS among people who have never smoked or who have quit smoking and substantial potential for full switching among adult smokers.
