Background: Tobacco is a global scourge that causes high morbidity and death. Doctors play a special role in combating tobacco use. Our purpose was to describe the characteristics of smoking behavior among Tunisian physicians (TP) and to identify their attitudes regarding patients' smoking. Methods: A descriptive cross-sectional survey was conducted with a questionnaire distributed to 266 TP in the Tunis region via Google Forms. Results: The smoking prevalence was 37.9%. The mean age of smoking onset was 19.5±2 years. It was during medical school in 52% of cases. Major reasons for initiation were the desire to experiment and the intention to cope with the stress of medical school or workload. Most TP (60%) were moderately dependent on smoking. Eighty TP (79.2%) reported serious consideration of quitting smoking at least once in their lifetime. Among them, 40 succeeded at least once. Reasons for quitting were the prevention of tobacco-related morbidity (44%) and the occurrence of some respiratory symptoms (30%). Relapse occurred during an abstinence period of fewer than 6 months in 47% of cases. Of the 266 TP, 109 (41%) thought that tobacco control is one of their practice's priorities. In addition, 30.2% thought that anti-smoking campaigns were effective, while 74.8% were in favor of banning smoking in public places, and 60% of them were in favor of increasing the prices. Conclusion: Despite a downward trend in smoking prevalence, there is still much work to be done to educate doctors on their role in tobacco control.
