Freebase nicotine is the purest, unmodified form of nicotine and has been the industry standard in cigarettes, nicotine replacement therapies, and traditional vape juices for decades. First chemically engineered by major tobacco companies in the 1960s, it is created by changing nicotine from its naturally occurring, acidic “salt” state into its most basic, standalone liquid form. This structural alteration increases its volatility and potency when heated, making it highly effective for vaporization. The Chemistry: How It Is Made
In its raw state inside tobacco leaves, nicotine exists as a protonated salt bound to organic acids. To “free” the nicotine, manufacturers treat the tobacco leaves with ammonia or other alkaline substances. Ammonia strips away protons from the nicotine molecules, shifting the substance up the pH scale to make it more alkaline. This deprotonated state allows the nicotine to evaporate at lower temperatures and cross biological membranes efficiently. Key Characteristics of Freebase Nicotine
Understanding how freebase behaves chemically translates directly to how it feels and how it is used:
