Nicotine Polacrilex and Nicotine Salt represent two distinct formulations in the realm of nicotine consumption. Nicotine Polacrilex is a resin complex where nicotine is intricately bound to a polymer called polacrilex. This composition finds its primary application in smoking cessation products, particularly in the form of nicotine gum. The structural design allows for a controlled and gradual release of nicotine, aiding individuals in managing withdrawal symptoms during the process of quitting smoking.

On the other hand, Nicotine Salt consists of nicotine molecules combined with other organic components. This formulation is commonly employed in e-liquids designed for vaping. Nicotine Salt offers a smoother and less harsh throat hit compared to traditional freebase nicotine, making it a popular choice among vapers seeking a milder experience.
