Article Correctness Is Author's Responsibility: E-cigarette users are exposed to potentially harmful levels of metal linked to DNA damage

(University of California - Riverside) Researchers at the University of California, Riverside, have completed a cross-sectional human study that compares biomarkers and metal concentrations in the urine of e-cigarette users, nonsmokers, and cigarette smokers. They found that the biomarkers, which reflect exposure, effect, and potential harm, are both elevated in e-cigarette users compared to the other groups and linked to metal exposure and oxidative DNA damage.
