An addictive drug found in tobacco.
A highly toxic alkaloid. Principal active ingredient in tobacco products and a controlled substance. Formerly used extensively as an insecticide for home, farm, and orchard. Nicotine in liquid form is readily absorbed through the skin (example = nicotine patch). Effects occur at many sites within the central and peripheral nervous systems of vertebrates and invertebrates. Mimics the action of the neurotransmitter, acetylcholine. Symptoms of toxicity in humans include salivation, abdominal cramping, headache, loss of coordination, and respiratory failure. Very water soluble. An aqueous extract, made by soaking the tobacco contents of one cigarette in 100 ml of water, will provide a potent stock solution from which serial dilutions can be made. Short-term treatment with these solutions will have major effects on Lumbriculus locomotion and blood pulsations (Lesiuk and Drewes, 1999). CAUTION: The aqueous extracts from even one cigar or cigarette may cause serious adverse effects in humans if ingestion or prolonged contact with the skin occurs.

The much beloved addictive substance found in cigarettes and tobacco products. Nicotine occurs naturally in the tobacco plant and is a constituent of tobacco smoke. It can also be found in other plants, but at much lower levels than in tobacco. Nicotine has mild pharmacological properties; it is thought to have a mild stimulant effect, similar to that of caffeine, and to contribute to the reduction in stress reported by many smokers. Many public health authorities believe nicotine is responsible for promoting and maintaining an addiction to smoking through its effects on the central nervous system.
A toxic substance present in tobacco and commonly used as an insecticide in agriculture. Large amounts can cause salivation, nausea, vomiting, diarrhea, headache, vertigo, reduced heartbeat and possible paralysis of the respiratory muscles. Treatment includes taking a weak solution of potassium permanganate, followed by activated charcoal and administration of artificial respiration.
A poisonous volatile alkaloid derived from tobacco and responsible for many of the effects of tobacco.
A chemical found in tobacco smoke.
An alkaloid (a nitrogen-containing chemical) made by the tobacco plant or produced synthetically. In the plant kingdom, nicotine is not restricted to tobacco but is widespread. The tobacco plant, Nicotiana tabacum, belongs to the nightshade family, which also includes potatoes, tomatoes, eggplant and red peppers. All contain nicotine. However, the concentration of nicotine in those vegetables is far lower than the level in tobacco. Nicotine has powerful pharmacologic effects (including increased heart rate, heart stroke volume, and oxygen consumption by the heart muscle) as well as powerful psychodynamic effects (such as euphoria, increased alertness, and a sense of relaxation). As is now well known, nicotine is also powerfully addictive. When someone becomes habituated to nicotine and then stops using it, they experience the symptoms of withdrawal, including anxiety, irritability, restlessness, shortened attention span and an intense, sometimes irresistible, craving for nicotine.

Nicotine is an alkaloid found in the nightshade family of plants (Solanaceae), predominantly in tobacco, and in lower quantities in tomato, potato, eggplant (aubergine), and green pepper. Nicotine alkaloids are also found in the leaves of the coca plant. Nicotine constitutes 0.3 to 5% of the tobacco plant by dry weight, with biosynthesis taking place in the roots, and accumulates in the leaves.
