The impact of tobacco on people

(1) Tobacco can cause nausea, dizziness, headache

Nicotine passes through the lungs After the mucosa and oral mucosa spread throughout the body and enter the brain, nicotine can imitate the effect of acetylcholine, a central neurotransmitter, and activate related nerves to release more dopamine. As the maintaining effects of dopamine, serotonin, and norepinephrine are strengthened, the person becomes more alert, more focused, and more able to relieve worry and endure hunger.

(2) Smokers develop tolerance to nicotine.

Regular smoking keeps nicotine levels in the brain at high levels. Neurogenic receptors are becoming less and less sensitive to nicotine, and the stimulating effect on dopamine release is also weakened. The original amount of cigarettes can no longer satisfy the smoker's pleasure, and the smoker develops tolerance to nicotine.
