A colorless, oily liquid alkaloid primarily obtained from the dried leaves of the tobacco plant (Nicotiana tabacum). Nicotine was named in 1550 for Jean Nicot after he sent tobacco seeds to Paris. It is a highly additive drug that is toxic in large doses. Commercially, purified nicotine is used as an insecticide, parasiticide, and fumigant. Nicotine turns brown when exposed to light or air.
