Pod-based ENDS devices that were introduced in mid-2010s contain high concentrations of nicotine in its protonated form (nicotine salt liquid) which are lower in pH and consist of nicotine conjugated with a weak base (eg, benzoic acid, levulinic acid).64 The addition of acid in nicotine salts allowed manufacturers to greatly increase the concentration of nicotine while avoiding harshness and bitterness.65 For example, JUUL that contains 5% nicotine salt solution was introduced in 2015 and has since become the most popular ENDS brand available in the USA.66 The availability of highly concentrated nicotine salt solutions seems to be an increasing market trend, as one recent report suggests that an online search showed more than 70 US ENDS brands containing more than 5% nicotine.67 Consumer appeal of ENDS, HTPs and ONPs Despite decades of research and development, the sensory properties of cigarette alternatives are still generally rated lower than cigarettes by smokers
