OBJECTIVE: Lung cancer is the most common malignancy, as well as the leading cause of cancer-related mortality worldwide. Several studies have shown the causative effect of cigarettes smoking in lung cancer, however, the effect of opium consumption has not yet been well studied. This study has been designed to evaluate the risk of developing lung cancer and pulmonary tuberculosis in pure opium addicts. MATERIALS AND METHODS: We designed an analytic case–control study with 490 participants. People were divided into three groups: Group A were pure opium addicts, Group B consisted of nonsmoker patients who visited the chest medicine clinic due to complaints such as asthma, respiratory tract infections, and other signs and symptoms unrelated to smoking. Group C were chosen from nonsmoker individuals who visited the Emergency Department due to nonrespiratory problems. RESULTS: Statistical analysis showed that the three groups were similar with respect to mean age and gender. In Group A, one patient was diagnosed as having bronchoalveolar carcinoma. No other case of lung cancer was found in all three groups. Furthermore, four patients in Group A (5.3%; 95% confidence interval, 1.3–10.3) were found to have pulmonary tuberculosis, as this was significantly higher as compared with groups B and C (P = 0.009 and P< 0.001, respectively). CONCLUSION: Although, owing to limited number of cases, a robust conclusion cannot be made, this study can be considered as a base for a well-designed, larger study to further clarify the potential effect of opium abuse in developing lung cancer.
