The popular conception of dopamine as reward/reinforcement is almost entirely incorrect. While your brain does use dopamine in reward-related signaling, it also uses it in aversion-related signaling, which is just the opposite.

(And levodopa is not addictive, contrary to the popular conception of dopamine.)
