Nic Salts

Salt nicotine e-liquids are designed to be different from standard juice.
Salt nics deliver a much smoother nicotine hit even when the level of nicotine is high.

These products are best suited to cig-a-likes and vape pens, and tanks with standard resistance coils.
It isn't recommended to use high levels of nicotine in low Ohm and sub-Ohm devices which often work at high power - the hit will be far too great to vape in many instances, however, some people do use high nicotine salt nic juices with certain low wattage sub-Ohm coils but they keep the power output very low.

Since the introduction of the typical 20mg salt nicotine e-liquids, there are now lower levels of nicotine available.
