The Relationship Between Chronic Low Back Pain and Cigarette Smoking Habits in Patients Treated with Conservative Therapy

Aim of the study: This paper focuses on the correlation of nicotine use with chronic lumbar back pain (CLBP). Methods: This is a cross-sectional observational study involving smoker and non-smoker patients with a diagnosis of chronic low back pain (CLBP), recruited during their initial neurosurgical consultation at the Neurosurgery Clinic over a period of 6 months. All patients were followed for a minimum of 3 months after the start of conservative therapy. Age, sex, smoking habits, and the presence of any comorbidities were noted. Pain severity and discomfort were evaluated using the Numeric Rating Scale (NRS), the DN4 questionnaire, and the Oswestry Disability Index (ODI). Based on imaging (MRI of the lumbosacral spine), diagnoses of disc herniation or vertebral lumbar stenosis were documented. Statistical analysis was performed using IBM SPSS Statistics software (Version 30). A p-value of less than 0.05 was considered statistically significant. Results: Improvement on the CLBP, NRS, and DN4 scales after the same conservative therapy was better in Patients with non-smoking habits improved more on the CLBP, NRS and DN4 scales when compared to smokers (NRS scale 0.001 and DN4 scale 0.027). Conclusions: Patients with smoking habitudes affected by lumbar disk her-niation and stenosis and undergoing conservative therapy had worse pain scores
