Smoking is responsible for several diseases, such as cancer, long-term (chronic) respiratory diseases, and heart disease, as well as premature death.
Smoke is inhaled through the mouth, and goes into the lungs, where nicotine is absorbed by the blood and reaches the brain in 7 seconds approx!
In the brain, nicotine increases the levels of Dopamine, a chemical that attaches to receptors on neurons in the brain when they “fire” {medicos to ignore this gross simplification}: just like cocaine.
