E cig juice
Electronic cigarette juice, more commonly called e cig juice, is the essence of the electronic cigarette, what gives the flavor and what becomes the vapor. There are hundreds of flavors out on the market including the more traditional “tobacco” and menthol flavors, but you can also find more odd and unique e cig juice flavors like strawberry daiquiri and boston cream pie. Usually, e cig juice is a mix of mainly water and propylene glycol or glycerin based flavors. They are used for their water retention ability (explained in the next paragraph) Nicotine is also added in the solution to fulfill the dose the consummer usually gets through smoking a regular tobacco cigarette.
Now you’re probably wondering, how does e cig juice become smoke? Here’s how. Flavors and nicotine are dissolved in hygroscopic components (hygroscopy is the ability of a substance to attract and hold water molecules from the surrounding environment), which when heated, evaporate the water that was retained in the propylene glycol or glycerin into smoke like vapor!
Health and safety
I can’t explain it better than Wikipedia does, here you go!
All three liquid bases are common food additives used in a variety of pharmaceutical formulations. Propylene glycol, the current dominating liquid base, has been utilized in asthma inhalers and nebulizers since the 1950s, and because of its water-retaining properties, is the compound of choice for delivering atomized medication. The U.S. Food and Drug Administration (FDA) includes propylene glycol on its list of substances Generally Recognized as Safe (GRAS), and it meets the requirements of acceptable compounds within Title 21 of the Code of Federal Regulations. In comparison, traditional tobacco cigarettes contain at least 80 cancer causing chemicals, including tar.
E cig juice sounds pretty safe to me, don’t you think? I would much rather inhale this than regular tobacco cigarette with all the cancer causing chemicals…
