For many people, smoking is an addiction. Cigarettes contain nicotine. Nicotine is very addictive. Smoking sends nicotine to your brain. The brain then releases certain chemicals that can have different pleasing effects. But the pleasure does not last long. When it wears off, your body may crave more nicotine. As you smoke, your body adjusts to nicotine and feels less pleasure.
