Pure nicotine concentrate refers to a highly concentrated form of nicotine that has been extracted and purified from tobacco plants or other natural sources. It is typically obtained through specialized extraction processes to remove impurities and achieve a high level of purity. Pure nicotine concentrate is commonly used as an active ingredient in various industries, including pharmaceuticals, vaping, agriculture, and research. It is often diluted and used in controlled amounts in products such as nicotine replacement therapies (NRTs), e-liquids for vaping, and insecticides. However, it's important to handle pure nicotine concentrate with extreme caution, as it is highly toxic in its concentrated form. Proper safety protocols should be followed during handling, storage, and use to prevent accidents or exposure.
