“Do e-cigarettes contain anti-freeze?
No. This myth was created by an infamous 2009 FDA press release regarding electronic cigarettes. The FDA tested only 18 cartridges from two companies. Of those 18 cartridges, one tested as positive for a non-toxic amount of diethylene glycol (approximately 1%).
While diethylene glycol is occasionally used in anti-freeze, the chemical is not a standard ingredient in e-cigarette liquid and it has not been found in any other samples tested to date.
The base liquid for general e-cigarette liquid is usually propylene glycol. Propylene glycol is considered GRAS (Generally Recognized As Safe) by the FDA and EPA. While it is also sometimes found in anti-freeze, it is actually added to make the anti-freeze less toxic and safer for small children and pets.
Propylene glycol is a common ingredient found in many of the foods we eat, cosmetics we use and medications we take. It is also used in the fog machines used in theaters and night clubs.”
Rest easy vapers. There is no anti-freeze in your juice.
