"DNA Changes in E-Cigarette Users Similar to Smokers, Study Finds"

A new study found that e-cigarette users had similar DNA changes in cheek cells as smokers, indicating potential health risks associated with vaping. While the study did not establish a direct link to cancer, the observed changes are associated with cell growth programs often activated in cancer. The research suggests caution in recommending e-cigarettes as aids for tobacco use cessation and highlights the need for additional studies to uncover their potential longer-term impacts on human health. The study's findings raise concerns about the perceived harmlessness of e-cigarettes and emphasize the importance of exploring the epigenome to predict future health and disease.
