Cigarette smoke is produced when the tobacco in a cigarette burns at temperatures in excess of 600°C. At such high temperatures, the tobacco is burned to ash and generates smoke that contains thousands of chemicals,1 including high levels of harmful and potentially harmful constituents (HPHCs) which are widely recognized to be the most likely causes of smoking-related diseases.2
Platform 1 (marketed as iQOS), on the other hand, heats tobacco without burning it (combusting) to generate a nicotine-containing aerosol with significantly lower levels of HPHCs.3 Because it is an electronic device, and because it generates an aerosol that is fundamentally different from cigarette smoke,4 some of the standard methods used to assess cigarettes cannot be applied and do not produce accurate measurements of certain aerosol constituents absent modification. You can download the full methodology which provides a detailed description of these modifications and step by step instructions for collecting the aerosol of platform 1 using a commercial linear smoking machine.

 For example, the iQOS aerosol contains about 80% water, whereas cigarette smoke contains only about 10% water.
