Top scientists from Philip Morris International have been working for over a decade to create a device that can respond to the growing need of adult smokers who cannot quit smoking and who want to take care of their health and the environment. IQOS is a device that does not burn tobacco and, as it has been scientifically proven, produces 90-95% less harmful ingredients than cigarettes, making this device a better choice for the health of adult smokers than continuing to smoke. A key difference between traditional cigarettes and IQOS is in the process of combustion of tobacco present in cigarettes, while in the case of IQOS tobacco is heated but not burned. During the burning of tobacco in the cigarette smoking process, tobacco smoke is released which contains a number of harmful constituents, and these are the main causes of smoking-related diseases.
