"Pure nic" typically refers to pure nicotine, which is a highly concentrated form of nicotine that is extracted and purified from tobacco plants or other natural sources. It is commonly used as an active ingredient in various industries, including pharmaceuticals, vaping, agriculture, and research. Pure nicotine is known for its potency and should be handled with extreme caution due to its toxicity. It is often diluted and used in controlled amounts in products such as nicotine replacement therapies (NRTs), e-liquids for vaping, and insecticides. When purchasing pure nicotine, it's essential to ensure that it is sourced from reputable suppliers who adhere to strict quality control measures and regulatory standards to ensure safety and purity.
