A nic salt E-Liquid is a different way of purifying the nicotine compared to the normal free-based nicotine liquids. A nic salt uses the same nicotine as a cigarette does. This means that you get a smoother and faster nicotine hit from nic salts, making them hugely popular since their launch! Nic salts tend to give a longer lasting nicotine hit, which means you can use your vape like you would smoke a cigarette, in smaller and less frequent doses.
