Nicotine salt vape juices (nic salts) contain nicotine in a state that more closely resembles the form of nicotine found in a tobacco leaf. Nic salts share a similar absorption profile with cigarettes meaning they will be absorbed into the bloodstream quicker than usual freebase vape juices. This usually culminates in needing to vape less often and getting a more satisfying vape hit each puff. Nic salts take freebase nicotine and add a natural acid to balance the pH levels. This creates a gentler feeling on the throat and a more neutral flavour profile. NOTE: Never use these nic salt juices in sub-ohm devices (usually the big vapes) because they administer more power than the smaller devices the nic salt vape juice is designed for.
