This explains context-dependent craving in addiction.93 Suppose an alcoholic has been clean and sober for years. Return him to where the alcohol consumption used to occur {e.g., that rundown street corner, that fancy men's club}, and those potentiated synapses, those cues that were learned to be associated with alcohol, come roaring back into action, dopamine surges with anticipation, and the craving inundates.
