E-liquid is the mixture used in vapor products such as e-cigarettes [28] and usually contain propylene glycol, glycerin, nicotine, flavorings, additives, and differing amounts of contaminants. [29] E-liquid formulations greatly vary due to fast growth and changes in manufacturing designs of e-cigarettes. [15]
The mixture used in vapor products such as e-cigarettes is called e-liquid. [33] E-liquid formulations vary widely. [27] [34] A typical e-liquid is composed of propylene glycol and glycerin (95%) and a combination of flavorings, nicotine, and other additives (5%). [35] [36] The flavorings may be natural, artificial, [34] or organic. [37]
Metal parts of e-cigarettes in contact with the e-liquid can contaminate it with metals. [15] Heavy metals and metal nanoparticles have been found in tiny amounts in the e-cigarette aerosol. [notes 6] [15] Once aerosolized, the ingredients in the e-liquid go through chemical reactions that form new compounds not previously found in the liquid. [17]
Used to transition to abstinence, e-cigarettes end the consumption of nicotine and the other harmful substances in tobacco smoke and later any harmful e-liquid ingredient. However, if abstinence is not achieved, e-cigarettes could mean increased nicotine dependence (by adding vaping to smoking) and ongoing harm from other e-liquid ingredients.
[281] [283] As such, the FDA has charged e-liquid products with branding that resembles food, candy, or beverage items as being misbranded and using false advertising, which is illegal under the Tobacco Control Act of 2009 (specifically sections 903(a)(1) and 903(a)(7)(A) of the Food, Drug, and Cosmetic Act, 21 U.S.C. § 387c). [281]
Another tactic used to imply the safety of these products is that the e-liquid containing nicotine is typically labeled as "e-juice" and promoted in candy and fruit flavors, such as cotton candy, gummy bear, chocolate mint, watermelon, and grape. [173] The fact that e-cigarettes contain nicotine is downplayed in e-cigarette advertising. [173]
