Nicotine is a highly addictive substance found in tobacco products. It stimulates the body's central nervous system, creating feelings of pleasure and relaxation. However, nicotine can also cause a range of side effects, including headaches.

When nicotine binds to nAChRs, it causes the blood vessels in the brain to constrict. This narrowing of the vessels reduces blood flow to the brain, which can lead to a headache.
