Vaping:  What you need to know? (link to article)

Despite the term “vaping” that’s associated with e-cigarettes, the devices produce an aerosol mist—not a vapour.

What’s the difference between a mist and a vapour?

An aerosol is the suspension of tiny solid or liquid particles in a gas. Clouds, mist, and fog are examples of aerosols.

A vapour is the gas phase of a substance that is typically solid or liquid at room temperature. Chlorine, for example, is a gas at room temperature so we refer to Cl₂ as chlorine gas, not a vapour.  Water, on the other hand, is a liquid at room temperature. So, when water molecules are in the gas phase, we refer to them as water vapor

How does the mist affect the lining of the lungs?

Q:  How to defeat a detector?

A:  Exhale into the toilet and flush this creates a vacuum that sucks the aerosol into the pipes. “There’s nothing we can do about that,” – “There’s no sensing that could ever change the laws of physics.”
