E-Cigarettes Can Leak Toxic Metals Into Vapers’ Lungs, Study Suggests.

Dentistry in the News

USA Today (2/23, May) reported that researchers at Johns Hopkins Bloomberg School of Public Health found “significant levels of highly toxic arsenic” and other potentially harmful metals in e-cigarette vapers, according to a study in Environmental Health Perspectives. The study’s samples also contained significant levels of chromium, manganese, nickel, and lead. Study senior author Ana María Rule, assistant scientist in the Bloomberg School’s Department of Environmental Health and Engineering, said, “It’s important for the FDA, the e-cigarette companies and vapers themselves to know that these heating coils, as currently made, seem to be leaking toxic metals – which then get into the aerosols that vapers inhale.”

Fox News (2/23, Dadourian) reported the research team “tested liquids in the refilling dispensers from 56 Baltimore area vapers and found potentially unsafe levels of arsenic, chromium, manganese, nickel and lead.” The results “also showed that aerosol metal concentrations were highest for e-cigarettes with more frequently changed coils.” Fox News points out that the FDA “has the authority to regulate e-cigarettes, but has not issued any rulings on the matter so far.”

U.S. News & World Report (2/23, Lardieri) reported, “Researchers are hopeful results of studies showing the harmful levels of toxic metals in e-cigarettes will help the FDA create rules to govern the devices.”
