Animal studies, in which brain cells can be carefully analyzed after nicotine administration, confirm the link between dopamine and addictive behavior.

What does nicotine do to dopamine?

Stimulation of central nAChRs by nicotine results in the release of a variety of neurotransmitters in the brain, most importantly dopamine. Nicotine causes the release of dopamine in the mesolimbic area, the corpus striatum, and the frontal cortex.
