Lead, other toxic metals could be inhaled while vaping, study says

For this study Ana and her team tested the e-cigarettes of 56 users for 15 different metals.

According to a study conducted by at Johns Hopkins Bloomberg School of Public Health, significant amounts of toxic metals, including lead, leaking from e-cigarette heating coils and are present in the aerosols inhaled by users.

Experts from Johns Hopkins University school of public health looked at vaping devices owned by 56 users.

While the liquid itself showed negligible traces of the toxins, researchers found significant levels of chromium, manganese, nickel, zinc and lead in the liquid in the e-cigarette and the aerosol of more than half the samples, according to the study.

The fact that minimal levels of metals were found in the e-liquids within the refilling dispensers, but levels 25 times higher were found in aerosols, led the researchers to believe the heating coils may increase the metal concentration. Vaping-inhaling this aerosol as if it were cigarette smoke-is popular especially among teens, young adults, and former smokers.

E-cigarette heating coils are normally made of nickel, chromium and a few other elements.

In an earlier study of users, researchers found nickel and chromium level in urine and saliva were high, meaning they were exposed to the materials from the aerosol.

Although the study was small, the authors say its findings are important and warrant evaluation by the Food and Drug Administration (FDA) due to the potential health consequences of exposure to these metals. Today the word on the e-streets is that E-Cigarette Vapor Found To Have Potentially Toxic Levels Of Lead & More.

While many of us have resorted to e-cigarettes as a way to curb our real smoking habit, it may be just as risky.

Nearly half of the aerosol samples had lead concentrations higher than limits set out by the Environmental Protection Agency.

However, the source of the lead and how metals get into the surrounding e-liquid remains a mystery. How the arsenic got into these e-liquids is yet another mystery-and another potential focus for regulators.

The scientists in the study concluded that exposure to heavy metals was not a significant health concern for people switching from tobacco to vaping, but was an "unnecessary source of exposure" for people who never smoked before.

The Maryland State Cigarette Restitution Fund, the Alfonso Martín Escudero Foundation, the American Heart Association Tobacco Regulation and Addiction Center, and the National Institute of Environmental Health Sciences funded the research.
