How does nicotine work in the brain?

When nicotine gets into the brain, it attaches to acetylcholine receptors and mimics the actions of acetylcholine. Recently, scientists discovered that nicotine raises the levels of a neurotransmitter called dopamine in the parts of the brain that produce feelings of pleasure and reward.
