Nicotine is addictive because its chemical structure is so similar to the neurotransmitter acetylcholine that once inside the brain it unlocks several other chemicals. One of these chemicals is dopamine, which produces a highly pleasant sensation. Another is adrenaline, which increases alertness. Yet a third is serotonin, which improves one's mood. When people are deprived of these chemicals, they naturally want more, and this leads to addiction.
