La nicotine est-elle modifiée par la chauffe ?
No, the nicotine molecule remains chemically intact during heating, as it possesses excellent thermal stability at standard vaping temperatures. It simply changes its physical state, moving from liquid to gas to be carried by the vapor, without its molecular structure being broken down or transformed into another compound.
Unlike tobacco, which destroys part of the nicotine through combustion while creating tar, vaporization preserves the integrity of the molecule for optimal efficiency. You would need to reach extreme pyrolysis temperatures, well above 300°C, to begin seriously degrading this alkaloid. Your nicotine therefore reaches your lungs exactly as it was, ensuring stable and controlled bioavailability.
