Pure nicotine for sale refers to the availability of highly concentrated nicotine products for purchase. This can include various forms such as liquid nicotine, nicotine salts, or nicotine powders. Typically, these products are utilized in industries like pharmaceuticals, agriculture, or vaping. In pharmaceuticals, pure nicotine may be used as an active ingredient in nicotine replacement therapies (NRTs) to aid smoking cessation. In agriculture, it serves as an effective insecticide for pest control. Moreover, in the vaping industry, it is commonly used to create e-liquids for electronic cigarettes. It's crucial to ensure that pure nicotine products are obtained from reputable sources and handled with caution due to their high toxicity.
