Nicotine

Nicotine \Nic"o*tine\ (? or ?), n. [F. nicotine. See Nicotian.] (Chem.) An alkaloid which is the active principle of tobacco ( C10H14N2). It occurs in tobacco plants ( Nicotiana tabacum and Nicotiana rusticum) to the extent of 2 to 8%, in combination with malic acid or citric acid. It is a colorless, transparent, oily liquid, having an acrid odor, and an acrid burning taste. It is intensely poisonous. The apparently addictive effects of tobacco smoking have been ascribed largely to the effect of nicotine, and the controlled administration of nicotine on various forms has been used as a technique for assisting efforts to stop the smoking habit.
--Ure.

Nicotine

Nicotine is a potent parasympathomimetic alkaloid found in the nightshade family of plants ( Solanaceae) and is a stimulant drug. Nicotine is a nicotinic acetylcholine receptor (nAChR) agonist, except at nAChRα9 and nAChRα10 where it acts as an antagonist. Nicotine is found in the leaves of Nicotiana rustica in amounts of 2–14%, the tobacco plant Nicotiana tabacum, Duboisia hopwoodii and Asclepias syriaca.

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; consequently, nicotine was widely used as an insecticide in the past and neonicotinoids such as imidacloprid are currently widely used.

Nicotine is addictive. An average cigarette yields about 2 mg of absorbed nicotine, and in lesser doses of that order, the substance acts as a stimulant in mammals, while high amounts (50–100 mg) can be harmful. This stimulant effect is a contributing factor to the addictive properties of tobacco smoking. Nicotine's addictive nature includes psychoactive effects, drug-reinforced behavior, compulsive use, relapse after abstinence, physical dependence and tolerance.

Limited data is available on the health effects of long term use of nicotine. The general medical position is that nicotine itself poses few health risks, except among certain vulnerable groups. Nicotine in the form of nicotine replacement products is less of a risk than compared to smoking. Nicotine is associated with a range of harmful effects, including potential birth defects and at high enough-doses, poisonings. In vitro studies have associated it with cancer, but carcinogenicity has not been demonstrated in vivo. There is inadequate research to demonstrate that nicotine is associated with cancer in humans. As medicine, nicotine is used to help with quitting smoking and has good safety in this form. During pregnancy, there are risks to the child later in life for type 2 diabetes, obesity, hypertension, neurobehavioral defects, respiratory dysfunction, and infertility. At high enough doses, nicotine is potentially lethal. It is unlikely that a person would overdose on nicotine through smoking alone. The use of electronic cigarettes, which are designed to be refilled with nicotine-containing e-liquid, has raised concerns over nicotine overdoses, especially with regard to the possibility of young children ingesting the liquids.
