Freebase

  1. Nicotine

    Nicotine is a potent parasympathomimetic alkaloid found in the nightshade family of plants. It acts as a nicotinic acetylcholine receptor agonist. It is made in the roots and accumulates in the leaves of the plants. It constitutes approximately 0.6–3.0% of the dry weight of tobacco and is present in the range of 2–7 µg/kg of various edible plants. It functions as an antiherbivore chemical; therefore, nicotine was widely used as an insecticide in the past and nicotine analogs such as imidacloprid are currently widely used. In smaller doses, the substance acts as a stimulant in mammals, while high amounts can be fatal. This stimulant effect is likely a major contributing factor to the dependence-forming properties of tobacco smoking. According to the American Heart Association, nicotine addiction has historically been one of the hardest addictions to break, while the pharmacological and behavioral characteristics that determine tobacco addiction are similar to those determining addiction to heroin and cocaine. The nicotine content of popular American-brand cigarettes has slowly increased over the years, and one study found that there was an average increase of 1.78% per year between the years of 1998 and 2005. This was found for all major market categories of cigarettes.
