No Smoking Day is an annual public health initiative that is aimed at promoting healthier lifestyles, encouraging smoking cessation, and increasing awareness of the detrimental effects of smoking on a global scale. To commemorate this occasion, we have selected ten smoking-related papers published in Antioxidants (ISSN: 2076-3921) in 2024 and 2025. These papers highlight recent advances and emerging insights into the mechanisms by which smoking and tobacco exposure induce oxidative stress, as well as the potential role of antioxidants in mitigating smoking-related damage. We hope these contributions provide valuable perspectives and stimulate further research and public health efforts in this important area.
