No, they don’t.
What may appear to be “smoke” or a white cloud coming from an e-vapor product (also know as a vape or e-cigarette) or heat-not-burn product is actually an aerosol. An aerosol is a suspension of fine solid and/or liquid particles in a gas (usually air).
However, whilst smoke (which is caused by burning and contains solid particles) is an aerosol, not all aerosols are smoke.
The aerosol created by heat-not-burn products and vapes is not formed by burning and does not contain solid particles.
The composition of the aerosol produced by smoke-free products is fundamentally different from smoke, which contains solid particles and over 6,000 chemicals, of which a hundred have been identified as harmful or potentially harmful.
As smoke-free products don’t burn tobacco, they can significantly reduce the average levels of harmful chemicals compared to cigarettes.*
*Importantly, smoke-free products are addictive and are not risk-free, but they represent a much better choice for adults than continued smoking.
