The culprit is nicotine in tobacco.
After nicotine enters the human body, it promotes the release and change of dopamine in the central nervous system of the body by acting on nicotine receptors, which makes people feel happy after the release of dopamine system in the midbrain and limbic system of the brain.
Smoking makes people feel happy is relative. If they feel happy temporarily after addiction, they will not feel happy when they are addicted, but they will also suffer and have a withdrawal reaction.
Smoking is addictive, mainly because nicotine in tobacco is at work. It enters the body and acts on the dopamine system of the brain, which is related to many pleasures.
