The next time you inhale the vapor of an e-cigarette, consider this: there may be toxic levels of metals -- including lead -- that could be leaking from the heating coils of your device.
This is the finding of a new study by researchers at Johns Hopkins Bloomberg School of Public Health, published yesterday in Environmental Health Perspectives.While the study is small—evaluating devices in a random sample of 56 users—it revealed that a significant number of the devices produced aerosols with potentially dangerous levels of lead, as well as other important metals such as chromium, manganese and nickel. Chronic exposure to such metals by inhalation has been linked to wide ranging effects--including cancer--on multiple organ systems including the lungs, brain, heart, liver, as well as the immune system.
Even though the FDA has the ability to regulate e-cigarettes, there has been no firm indication if, or how, it may choose to address findings by this and previous studies regarding the toxicity of the contents of the vapor. But it’s fair to say that the FDA will likely have a say by issuing future rulings on this important matter.
"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," said Ana María Rule, PhD, MHS, the senior author of the study in a press release.
