Pure nicotine refers to nicotine that has been isolated and purified from tobacco plants or other natural sources. It is a highly concentrated form of nicotine and is typically obtained through extraction and purification processes to remove impurities and achieve a high level of purity. Pure nicotine is commonly used as an active ingredient in various products and industries, including pharmaceuticals, vaping, agriculture, and research. However, it's important to handle pure nicotine 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. Additionally, accurate measurement and dilution are crucial when using pure nicotine to ensure safety and consistency in the final product.
