WTAs work by better emulating the effect of cigarettes by including both the main alkaloid, nicotine, as well as the background alkaloids that naturally occur in the tobacco plant: nornicotine, anatabine, and anabasine. Alkaloids are the nitrogenous compounds found in almost all plants and in many cases interact in some way with the human body, background alkaloids are the ones found in smaller amounts. By including the full spectrum of the tobacco plant's alkaloids and in the same ratio, WTAs are able to provide a more complete vaping experience: the stimulating effect of nicotine is modified by the background alkaloids to create an overall effect that is both stimulating and relaxing.
