What are the benefits of nicotine?

Nicotine may briefly enhance focus, mental performance, alertness, and motivation, while also affecting muscle tone and sympathetic activity. 1

• 1. Cognitive function: It may promote cognitive function and could protect against some forms of cognitive impairment. 2
• 2. Dopamine and motivation: By increasing dopamine release in the nucleus accumbens, nicotine can briefly boost wellbeing, alertness, and motivation. 3
• 3. Acetylcholine and attention: Increased acetylcholine can sharpen attention and focus on the task at hand; the effect is transient. 4
• 4. Muscle and sympathetic effects: Nicotine may somewhat relax skeletal muscle while increasing heart rate and blood pressure, raising sympathetic activity and preparing the body for action. 5 6
• 5. Risks and development: Risks depend partly on how nicotine is delivered; smoking, vaping, dipping, and snuffing can harm health. Nicotine should generally be avoided during brain development, especially in young people, and it can lead to dependence. 7 8
