Metals emitted from e-cigarettes are not a reason for health concerns.


Published in the International Journal of environmental research and Public Health, Cardiologist Dr Farsalinos has looked into the risk assessment analysis of the levels of metals emitted in e-cigarette aerosol as found in two previous studies.

The analysis was done due to Dr Farsalinos’ dissatisfaction with the original studies and the misrepresentation of the findings within them.

The new risk analysis deliberately overestimated the daily use of e-cigarettes, though they did stick to the current available regulatory safety limits, with the findings positive for vapers.

Dr Farsalinos wrote,  “We started with Permissible Daily Exposure Limits (PDEs) for inhalational medications, as defined by USP. We found that for cadmium, chromium, copper, lead and nickel, the average daily exposure levels from e-cigarette use were 2.6-37.4 times lower compared to acceptable intake from inhalational medications. For manganese we used the Minimal Risk Level (MRL) defined by ATSDR, with exposure from e-cigarette use being 325 times lower than the MRL. For aluminum, barium, iron, tin, titanium, zinc and zirconium we used the Recommended Exposure Limits (RELs) defined by NIOSH. Exposure from e-cigarette use was 665-77,500 times lower compared to RELs.”

Dr Farsalinos noted that the studies were done using 1st generation electronic cigarettes, and that it is important that the research be expanded to include 3rd generation devices.

He concluded, “The results of our risk assessment analysis clearly show that exposure to metals from e-cigarettes is not expected to be of significant health concern for smokers who switch to e-cigarette use. However, there is the need to improve the quality of the products, to further reduce unnecessary exposure. Finally, there is no reason for a non-smoker to be exposed to any levels of metals, thus, we do not recommend use of e-cigarettes by never smokers.”
