Also known as Nicotine Addiction and Nicotine Dependence
Nicotine is a potent parasympathomimetic alkaloid found in the nightshade family of plants (Solanaceae). 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.Source: Wikipedia
