Bupropion works as an antidepressant partly by inhibiting the reuptake of dopamine (and norepinephrine), which elevates dopamine levels in the brain. This mechanism is thought to be related to its effectiveness in reducing nicotine craving and withdrawal symptoms in tobacco addiction, as nicotine itself increases dopamine levels when it activates nicotinic acetylcholine receptors.
