Nicotine

Nicotine is the primary psychoactive and highly addictive compound found in tobacco products. When consumed, it is rapidly absorbed into the bloodstream and reaches the brain, where it stimulates the adrenal glands to release adrenaline. This causes an immediate increase in heart rate, blood pressure, and alertness. Nicotine also significantly increases levels of the neurotransmitter dopamine in the brain's reward circuits, producing temporary feelings of pleasure and relaxation, which strongly reinforces its use and leads to addiction. Long-term use can alter brain chemistry, impacting mood, concentration, and impulse control, and withdrawal often causes irritability and anxiety.
