What does nicotine mean?
Nicotine is the alkaloid that makes tobacco products addictive and is also found in plants such as tobacco. It acts as a stimulant by affecting the nervous system, and exposure can lead to dependence, withdrawal symptoms, and increased heart rate and blood pressure. Nicotine is especially associated with cigarettes, cigars, chewing tobacco, vaping products, and nicotine replacement therapies such as patches and gum. In medical and research language, it may refer specifically to the purified chemical or to administering that chemical. The word is also used figuratively when discussing dependence, for example in “nicotine addiction.” Although nicotine is the substance chiefly responsible for tobacco addiction, it is not the only harmful component of tobacco smoke. Its name commemorates Jean Nicot, a sixteenth-century French diplomat associated with introducing tobacco to France. Nicotine is therefore both a familiar feature of everyday language and a significant substance in pharmacology, public health, and the history of tobacco.

Where does nicotine come from?
The word nicotine comes through French from Nicotiana, the botanical genus that includes the tobacco plant. Nicotiana itself was named in honor of Jean Nicot, the French diplomat whose writings and shipments helped introduce tobacco to France. The chemical was isolated and named in the early nineteenth century, following the plant's established name.
