"Nicotine pure" refers to nicotine in its unadulterated form, without any additives or dilutions. This highly concentrated substance is typically derived from tobacco plants and is known for its potent effects. Nicotine pure is used in various industries, including pharmaceuticals, pesticides, and vaping products. In pharmaceuticals, it may be used in nicotine replacement therapies to help individuals quit smoking. In agriculture, it may be used as a natural insecticide due to its toxic effects on insects. In vaping products, it serves as a key ingredient in e-liquids, providing users with nicotine delivery in vaporized form. Due to its high toxicity, handling nicotine pure requires caution, and proper safety measures should always be followed.
