When nicotine binds to nicotinic acetylcholine receptors in the nervous system, it stimulates the release of several key neurotransmitters, including:
- Dopamine
- Norepinephrine
- Acetylcholine
- Serotonin12
The release of these chemicals influences various bodily and cognitive functions, such as attention, learning, mood, heart rate, and reward processing. Specifically, the release of dopamine within the brainās reward pathways is a primary driver of nicotineās highly addictive nature, as it reinforces the behavior and encourages repeated use.123
