What is Nicotine?

Nicotine is an alkaloid that makes about 3% of dry tobacco weight, mainly in the roots and leaves of the plant known as Nicotania tabacum, that was named after Jean Nicot de Villemain, in the 16 century France. Nicotine can be also found in other plants of the nightshade family, but in much smaller quantity.

Nicotine has an antiherbivore effect, lethal to insects, and was widely used as an insecticide in the late 17 century. United States Environmental Protection Agency (EPA) in 2008 prohibited the use of Nicotine sulfate and any nicotine-based pesticides due to their high toxicity to humans and their quick absorption thru the skin.

Nicotine mainly affects the brain. In high concentration nicotine is lethal to humans(30-60mg) while in small concentration, like in the cigarettes where it is around 1mg it acts as a stimulant to the brain, but which is enough to cause addiction to nicotine thru smoking.

When u finish a cigarette the euphoria and nicotine effects disappear, which cause the human body to want to feel it again and thus wanting to smoke more, which brings the addiction to nicotine.

This is also dependent on the amount of nicotine consumed.
