Moreover, using premium E-Liquids, preferably with more vegetable glycerin (VG) and less propylene glycol (PG), can help reduce potential irritation to the throat and lungs. The most important factors in vaping safely come down to maintenance.

The earliest e-cigarette can be traced to American Herbert A. Gilbert, who in 1963 applied for a patent for "a smokeless non-tobacco cigarette" that involved "replacing burning tobacco and paper with heated, moist, flavored air". This device produced flavored steam without nicotine. The patent was granted in 1965.

Invention of the e-cigarette Hon's original goal was to help himself quit smoking cigarettes. Ultimately, this did not work. He is now a dual user, both smoking and vaping. He filed patents on his invention in China, the United States and the European Union based on his 2003 priority application in China.
