“‘Drug craving triggered by cues, such as the sight, smell, and other sensory stimuli associated with a particular drug like cocaine, is central to addiction and poses an obstacle to successful therapy for many individuals,’ says NIDA Director Nora D. Volkow, lead author on the study and former Associate Laboratory Director for life sciences research at Brookhaven Lab. ‘Today we can actually see increases in specific brain activities that are linked to this experience. If we can understand the mechanisms related to cue-induced craving, we can develop more effective treatment strategies to counteract it.'” (ScienceDaily)
