Well a few things that need to be taken in consideration.
Nic Salts were initially created for use in pod systems, to guarantee a higher nicotine with less of the unpleasant throat hit, as well as flavor loss.
Then we moved on to getting nic salts at already lower mg’s etc.
Here’s my take on it, if you are not a recent smoker trying to quit, not using it in a pod system or vaping at lower strength 1-12mg) then there’s no reason to use it.
Nic Salts if used below 9mg does have no impact on flavor if used in the correct device. Above that, flavor needs to be increased.
It oxidized slower than free base, leading to a different result in some juices if a side by side comparison is done. sometimes to the better, sometimes to the worse.
You can not drip/use it with a rda. It will have a metallic and unpleasant taste, in my experience, even if very low strength.
Vaping it in a tank/rta above 50watts created that same problem, I think NR even has a warning on their webpage saying something like low wattage usage.
Some people reporting immense dizzyness, tight chest and pain etc. after usage of nic salts over a longer period of time. (If you’re sensitive to it) others saying that nic salt makes you vape more because of the higher cravings. (Again if you 're sensitive to it)
And while that might not apply to you, it’s worth mentioning before making the switch.
Edit: it hits harder but only at “higher” strength. Let’s say you vape 3mg free base, you can’t put 2mg or 1mg salt and get the same effect lol. But you can use a 18mg if you normally vape 24mg etc.I
Regarding the calculatator, it mixes the same as freebase, so there’s no reason to have a seperate/extra field. Just plug it in the same as regular freebase.
