    GlossaryNicotine

    highly addictive stimulant found in tobacco plants

    Nicotine is a highly addictive chemical compound found in tobacco plants. It acts as a stimulant in small doses, increasing heart rate and alertness, but can be toxic in larger amounts. Nicotine binds to nicotinic acetylcholine receptors in the brain, leading to the release of neurotransmitters like dopamine, which contributes to its addictive properties.
