Isn't it the same thing Big Tobacco was blamed for?
Tobacco companies were increasing "hit" from nicotine. Doesn't nicotine salts have the same quality?
I think you have it backwards
@Alien Traveler,
Nicotine, as it naturally occurs in tobacco leaves, is in the form of salts. Tobacco companies got the black eye for using ammonia (and other toxic chemicals) to convert these salt forms to freebase form; which is the form that is more readily bio-available, and therefore provides better hit ("hit" meaning better/faster absorption; and not to be confused with throat hit).
@dannyv45 has a great article (in 2 parts) on it in his blogs here:

As for nic salts being used in e-liquids; I have read two basic rationals. One is, when used in tandem with our regular nicotine, it can provide another "layer" of nicotine that some find helpful when try to quit using tobacco products (similar to WTAs). The other, was when the pod-style vapes were (are being) developed; as they could use the salts at much higher (as much as 48-50mg/mL?) strengths
without having excessive/prohibitive throat-hit.
What NN might be adding to their formulation to
increase throat-hit; I have ZERO clue.
I should add: I am not even
remotely educated in chemistry; so I may be 100% wrong, but this is as I understand it. I welcome any, and all, corrections.
