"Pure nicotine" refers to highly concentrated nicotine extract, typically derived from tobacco plants. This form of nicotine is extensively purified to remove impurities and contaminants, resulting in a potent and nearly pure substance. It is commonly used in various applications, including pharmaceuticals, nicotine replacement therapy, insecticides, and research. Pure nicotine is available in different forms such as liquid, powder, and resin, offering versatility in usage. Due to its high potency, pure nicotine must be handled with caution and stored securely to prevent accidental ingestion or exposure. It plays a crucial role in nicotine-based products and industries, providing effective solutions for smoking cessation, pest control, and scientific investigations.
