About 20% to 27% of propylene glycol and glycerin-based liquid particles are inhaled. [226] A 2016 study reported that 6% of nicotine, 8% of propylene glycol, and 16% of glycerin was exhaled. [75]: 162 As of 2014 the long-term effects of inhaled propylene glycol [202] [174] and glycerin were unknown. [197]
E-liquids usually contain propylene glycol, glycerin, nicotine, flavorings, additives, and differing amounts of contaminants. [29] E-liquids are also sold without propylene glycol, [30] nicotine, [31] or flavors. [32] The benefits and the health risks of e-cigarettes are uncertain. [33] [34] [35] There is tentative evidence they may help people ...
Estimates on the prevalence of propylene glycol allergy range from 0.8% (10% propylene glycol in aqueous solution) to 3.5% (30% propylene glycol in aqueous solution). [ 70 ] [ 71 ] [ 72 ] The North American Contact Dermatitis Group (NACDG) data from 1996 to 2006 showed that the most common site for propylene glycol contact dermatitis was the ...
Fruit flavored e-liquid is the most commonly marketed e-liquid flavor on social media. [ 360 ] E-cigarette companies commonly promote that their products contain only water, nicotine, glycerin, propylene glycol, and flavoring but this assertion is misleading as researchers have found differing amounts of heavy metals in the vapor, including ...
Glycerin was long thought to be a safe e-liquid additive. However, formaldehyde is a known product of propylene glycol and glycerol vapor degradation, [15] and may cause lung inflammation. [16] Lipid pneumonia is known to cause lung inflammation, with exogenous and endogenous factors that cause this disease. [citation needed]

E-liquids usually contain propylene glycol, glycerin, nicotine, flavorings, additives, and differing amounts of contaminants. [59] E-liquids are also sold without propylene glycol, [60] nicotine, [61] or flavors. [62] The benefits and the health risks of e-cigarettes are uncertain.
E-liquid containing glycerin and propylene glycol delivers nicotine more efficiently than a glycerin-based liquid with the same amount of nicotine. [97] It is believed that propylene glycol vaporizes quicker than glycerin, which subsequently transports a higher amount of nicotine to the user. [97]
