Heating instead of burning
In HEETS the tobacco is not burnt, but heated. HEETS releases a real tobacco taste that is different and less harsh, than what you are used to with a cigarette. HEETS has no smoke, no ash and less smell than cigarettes. Smokers who have switched to IQOS say that there is less unpleasant feeling and aftertaste left in their mouth compared to after finishing smoking a cigarette.
