Salt Nicotine eLiquid Refills are basically what their name suggests; eLiquids that use the natural salt that is found within the tobacco leaf as their basis for nicotine.
Vaping a Nic Salt eLiquid allows nicotine to be absorbed into the body at a faster rate than standard eLiquids, allowing the user to experience a more “natural” nicotine rush that’s more similar to smoking a tobacco cigarette. Salt-based nicotine eLiquids aim to provide a more potent nicotine hit than most eLiquids can currently provide.
