An aerosol is a suspension of fine solid particles and/or liquid droplets in a gas (usually air). 

Cigarettes generate a smoke aerosol that is the result of the combustion (burning) of tobacco, and contains carbon-based solid particles

While smoke is an aerosol, an aerosol that is not generated by burning, and therefore does not contain solid particles, is not smoke.

Our heated tobacco and e-vapor products do not produce smoke because they do not burn tobacco. Instead, they generate a nicotine-containing aerosol, either by heating tobacco or through other technologies that do not involve combustion. 

Consumers typically use the term vapor to refer to the aerosol generated from heated tobacco products or other nicotine-containing products.
