What does narcotine mean?
Narcotine is a poisonous alkaloid found in tobacco and related plants. Although its name may suggest a close relationship to the familiar drug nicotine, the two are distinct compounds: nicotine is the principal psychoactive substance in tobacco, while narcotine is known chiefly for its toxic effects. Narcotine has consequently appeared mainly in scientific, medical, and toxicological contexts rather than in everyday language. The word also reflects the broader history of the Greek root narkē, meaning numbness or stupefaction, which gave English words such as narcotic and narcosis. Knowing narcotine is useful for distinguishing the many chemically different alkaloids associated with tobacco, and for understanding why tobacco exposure involves a mixture of substances rather than a single compound.
nounNarcotine is a poisonous alkaloid found in tobacco and related plants, chemically related to nicotine. It is not the principal psychoactive component of tobacco and is chiefly of historical, toxicological, and chemical interest.
- A poisonous alkaloid found in tobacco and related plants, chemically related to nicotine.
"The toxic effects of narcotine were studied long before the structure of tobacco alkaloids was fully understood."
"Researchers identified narcotine as one of the alkaloids present in tobacco smoke."
"The toxicological effects of narcotine differ substantially from those of nicotine."
Usually used in the singular when referring to the compound; plural forms are possible when referring to multiple samples or quantities.
"The researchers compared narcotines isolated from different tobacco samples."
Narcotine shares a name with the Greek root meaning numbness, a clue to its long history as a toxic substance.

Where does narcotine come from?
Narcotine was named in the nineteenth century as an alkaloid associated with tobacco, using the Greek narkē, meaning numbness or stupefaction, together with the chemical suffix -ine. Its name belongs to the same etymological family as narcotic, narcosis, and related terms describing the induction of numbness or a drugged state. The compound itself is chemically related to nicotine, although the two alkaloids have different pharmacological properties.
How narcotine is actually used
Narcotine is a technical or historical term. In modern discussion, it is much less common than nicotine and is used mainly in toxicology, pharmacology, and the history of tobacco chemistry.
Easily confused with narcotine
Nicotine is the well-known psychoactive tobacco alkaloid that primarily stimulates the brain's reward pathways, whereas narcotine is a different alkaloid known chiefly for its toxic effects.
