What are the differences between smoke and aerosol?

''To summarize: while smoke is an aerosol, not all aerosols are smoke. Smoke contains solid particles and thousands of chemicals that are generated at high temperatures when a material combusts, whereas an aerosol that is formed at lower temperatures from vaporization/condensation is much less complex than cigarette smoke and no solid particles are generated. This is why it’s so important for smoke-free products to avoid combustion, as it’s combustion that generates smoke.''

Dr. Markus Nordlund, Global Head Life Sciences Special Projects, led PMI's computational fluid dynamics activities for multiple years and actively contributed to the development of a simulation software for aerosol physics and biomass thermodynamics used to develop and assess PMI's smoke-free products. In his presentation, Markus explains some of the biggest differences between cigarette smoke and heated tobacco aerosol.
