Is the vape a smoke?
The fog of vape looks white, and the smoke produced by cigarettes is the real "smoke". 92% of these flue gases are 8% of the gas is solid, and those solids have a particle size of about 0.1-2μm. , far less than the wavelength of light, so "Rayleigh scattering" occurs between tiny solids (in fact, with some "small scattering"), the shorter wavelength blue-violet light in the solar spectrum is more obvious than the longer wavelength red light scattering. So, the smoke of the cigarette shows a "cyan" instead of the "white" like the electronic smoke.
On the other hand, in our inertia thinking, when it comes to smoking, it is tobacco. Vapes are not tobacco, but because e-liquids contain nicotine.
So what is vape, vape is nothing else, vape is vape, a way to get nicotine, or a way to entertain with smoke.
You can't say that vape are smoke because vape contain nicotine. Coffee and tea, as well as various functional drinks, contain caffeine, but no one will confuse them.
