Emotional arousal of graphic cigarette warning labels loses its beneficial effects on craving reduction after repeated exposure – A longitudinal neuroimaging study

Key Points

• Cigarette craving diminishes as emotional arousal from graphic warning labels decreases over time.
• Significant habituation effects were observed in amygdala reactivity with repeated exposure to high-arousal graphic warning labels.
• Observational analysis highlighted the insufficient long-term benefits of high-arousal graphic warning labels compared to low-arousal alternatives.
• Low-arousal graphic warning labels may offer a more effective and legally viable strategy for tobacco control efforts.
