Abstract
Nicotine and tobacco use are more common among orthopedic trauma patients than in the general population and have significant implications for pain management and recovery outcomes. This narrative review synthesizes clinical, epidemiological, and mechanistic research to examine the bidirectional relationship between nicotine/tobacco use and pain. We explore how nicotine/tobacco exposure disrupts pain modulation, delays healing, and increases the risk of chronic pain, while also highlighting evidence that acute pain relief reinforces nicotine/tobacco dependence through negative reinforcement processes. We propose a conceptual framework to integrate these findings, and we highlight psychosocial, medical, and transdiagnostic mechanisms that may sustain interrelationships between pain and nicotine/tobacco use. Additionally, we review existing interventions, barriers to integrating smoking cessation into orthopedic trauma care, and opportunities for multidisciplinary approaches to improve patient outcomes. By addressing both nicotine/tobacco use and pain as interdependent targets, healthcare providers may enhance recovery, reduce post-trauma disability, and improve smoking cessation success. Future research should prioritize the development of tailored interventions that mitigate these effects and optimize orthopedic trauma care.
