Pure nicotine liquid is a highly concentrated form of nicotine used in various industries, including vaping, pharmaceuticals, and agriculture. It is typically derived from tobacco plants and undergoes purification processes to remove impurities and achieve high levels of purity. In the vaping industry, pure nicotine liquid is used to create e-liquids with different nicotine strengths to cater to the preferences of vapers. In pharmaceuticals, it may be used in nicotine replacement therapies (NRTs) to help individuals quit smoking by reducing withdrawal symptoms. In agriculture, it can be used as a pesticide to control pests in crops, although its use is highly regulated due to its toxicity. Pure nicotine liquid should be handled with care and diluted properly before use due to its high potency and toxicity.
