Conventional nicotine is also known as "freebase" nicotine. Nic salt is the kind of nicotine found in leaves of tobacco. The salts contain not only nicotine but various other organic components. Nic salt is a compound where the nicotine is bonded to other chemicals. This is not the case with freebase nicotine. Studies have been carried out which suggest nic salts were more efficient in delivering nicotine to users, including an experiment conducted by PAX Labs.Many experiments have taken place with the aim of improving the efficiency of nic salts.

• Better, faster nicotine fixes that deliver in 6-7 seconds. Why? Freebase nicotine takes longer for the satisfaction feeling- it's absorbed by the body in a build-up way. If anyone can get crankier faster than a six week-old baby, it's a quitting smoker craving their hit. Nic salts allow the nicotine to enter the bloodstream at a similar speed to cigarettes- exactly what quitters are looking to replicate. Switch to nic salts and your nicotine is basically on demand.
• It's technically cheaper. While nic salts themselves are a touch pricier, your e-cigarette will deliver nicotine more efficiently. That technically translates to vaping less, consuming less juice, and hey presto, more cash in the bank.
• Way better shelf life. Since nic salts are more chemically stable than conventional e-liquids, they store much better and longer. The quality of the nicotine never fades.
• Smooth, mild throat hit.. The scientists did the work. They figured out that nic salts without the added food-grade benzoic acid actually absorb less efficiently. .

The juice is designed to mirror the hit that you would achieve from a cigarette. The salts are absorbed into the bloodstream much faster, delivering an effect within around 6-7 seconds. They have also helped many vapers to reduce their liquid consumption thanks to the more powerful nicotine hit on offer.
