Experts Debate: Can E-Cigarettes Help Quit Smoking and Reduce Lung Cancer Risk?

Aug.15.2022
The debate over whether e-cigarettes can help smokers quit and reduce the risk of lung cancer continues among experts.

As it is widely known, smoking is the leading cause of lung cancer. According to the Centers for Disease Control and Prevention (CDC), smokers are 15 to 30 times more likely to develop lung cancer than nonsmokers. However, quitting smoking is a difficult task. Due to the addictive nature of smoking, 52-63% of lung cancer patients continue to smoke even after being diagnosed.


There is controversy within the medical community about whether or not vaping can reduce the risk of lung cancer by inducing smoking cessation.


On the 8th of this month, the World Lung Cancer Association held a heated debate on the effectiveness of e-cigarettes in helping smokers quit. Lung cancer clinical physician Matthew Avison, who has treated hundreds of lung cancer patients in clinical trials, stated that "hundreds of chemicals will enter the body during the process of smoking tobacco. Patients struggling to quit smoking need an alternative." He believes that "a principle of not burning tobacco but vaporizing liquid makes it easy to understand that e-cigarettes are less harmful." Avison continued by referencing a study that found e-cigarette users who switched from traditional smoking had quit smoking for at least 6 months. He believes that this should be seriously considered as an alternative method for smoking cessation.


However, there are also opposing views. Emily Stone, a professor at St Vincent Hospital in Sydney, expressed in a discussion on the same day, "The effect of e-cigarettes on smoking cessation varies depending on the research methods. The fact is," she said. Professor Stone stated, "E-cigarettes contain fewer toxic substances than tobacco cigarettes, but the risk is at an uncertain level.
