Pure liquid nicotine is a highly concentrated form of nicotine that is commonly used in the production of e-liquids for vaping. It is derived from tobacco plants and undergoes purification processes to remove impurities, resulting in a clear and potent liquid. Pure liquid nicotine is available in various concentrations, allowing vapers to customize the nicotine strength of their e-liquids according to their preferences. However, it's important to handle pure liquid nicotine with caution, as it is highly toxic in its concentrated form. Proper safety precautions should be followed, and it should be stored securely away from children and pets.
