Nicotine salts are a form of nicotine that is found naturally in tobacco leaves. They are different from the nicotine commonly used in e-cigarettes and vaping liquids, which is typically in a freebase form. Nicotine salts are created by combining nicotine with an acid, such as benzoic acid, which lowers the pH level and results in a smoother vaping experience. They are known for delivering nicotine more efficiently and providing a smoother throat hit compared to freebase nicotine. Nicotine salts have gained popularity among vapers, especially those looking for a stronger and more satisfying nicotine delivery without the harshness often associated with higher nicotine concentrations.
