Nicotine Salts (Nic Salts) are extracted directly from natural tobacco leaf, whereas traditional e-liquid is made using a form of artificial nicotine called 'free base'.
Nic salts are absorbed to the body far quicker than standard e-liquid, so it provides a much quicker hit to keep your nicotine cravings at bay. In addition to this, they eliminate that harsh throaty hit and aftertaste as its smoother even after being heated by your vaping device.
High Strength free base nicotine can be quite harsh on the throat and can cause discomfort for some vapers, especially new vapers.
Nic Salts are reccomended to be used in a Pod style Vaping device, or devices with coils 1.0ohm - 1.6ohm.
