Combined Smoking and Vaping Increasing Health Risks, New Study Finds

A recent study highlights the ongoing health concerns associated with the simultaneous use of cigarettes and e-cigarettes, often referred to as dual-use. Contrary to some beliefs that switching to vaping can reduce the risk of cancer, researchers found that individuals who both smoke and vape are exposed to similar harmful substances as regular smokers. The study analyzed data from nearly 2,700 adults involved in a long-term federal tobacco research project.

Findings revealed that dual users exhibit higher levels of tobacco-specific nitrosamines, substances known to be probable carcinogens, compared to those who only vape. Additionally, dual users showed elevated levels of volatile organic compounds linked to cancer. These results suggest that using both products does not mitigate health risks and may, in fact, compound exposure to harmful chemicals.

Lead researcher Zheng Xue from the American Cancer Society emphasized that dual-use does not offer a safe alternative and underscores the importance of effective cessation programs. Experts recommend that smokers seek support through proven methods like medications and counseling to quit nicotine and tobacco altogether.

Public health authorities stress the need for stricter regulation of tobacco products, including e-cigarettes, to prevent illegal products from reaching consumers and to reduce overall tobacco-related health risks. The findings underscore that attempting to reduce harm by dual use is ineffective and that complete cessation remains the most health-conscious choice.
