The E-cigarette ‘smoke’ is actually a vapor that is generated by the vaporization of cartridge solution using the technology named Supercritical Atomization, during which the components in the cartridge solution are transformed into a gaseous state. The smoke that is released from the E-cigarette is simply a harmless vapor that evaporates into the air within seconds. E-cigarette leaves no residue in the air, and it will not harm anyone around you.

No chemical reaction happens during vaporization and consequently E-cigarette vapor is safe, because all the components that make up the cartridge solution have well-known safety records, and these constituents are widely used in the pharmaceutical and food industries.
