PMI
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, including high levels of harmful and potentially harmful constituents (HPHCs), which are widely recognized to be the most likely causes of smoking-related diseases.
The Tobacco Heating System (THS or IQOS, its commercial name), on the other hand, heats tobacco without burning it (combusting) to generate a nicotine-containing aerosol with significantly lower levels of HPHCs. HPHC levels can be measured by collecting the aerosol from IQOS, using a commercial linear smoking machine. This document provides a detailed description of how the device should be used in this context and step by step instructions for collecting the aerosol of IQOS using a commercial linear smoking machine.
PMIScience.com is operated by Philip Morris International for the purpose of publishing and disseminating scientific information about Philip Morris International’s efforts to develop and assess products that have the potential to reduce individual risk and population harm associated with tobacco use. This site is for use by scientists, the public health and regulatory communities, and other stakeholders with an interest in tobacco policy. The purpose of this site is not for advertising or marketing. It is not intended for use by consumers.
Reduced Risk Products ("RRPs”) is the term we use to refer to products that present, are likely to present, or have the potential to present less risk of harm to smokers who switch to these products versus continuing smoking. PMI has a range of RRPs in various stages of development, scientific assessment and commercialization. Our RRPs are smoke-free products that produce an aerosol that contains far lower quantities of harmful and potentially harmful constituents than found in cigarette smoke.
