Dangerous Metals in Vaping Put Into Context

Exposure to risky toxins is a regular feature in mainstream media vaping coverage, and it would be a valid concern if the studies being covered by the press were honest scientific inquiries. Unfortunately, they’re often not. Research is frequently designed to facilitate anti-vaping propaganda.

Back in February, we covered a Johns Hopkins University study that purported to find dangerous levels of metals in e-cigarette vapor. The study was briefly a fixture in news coverage, as many scary vaping stories are. Reporters covered the Hopkins study uncritically, assuming that the research was legitimate and meaningful.

“Almost 50 percent of aerosol samples had lead concentrations higher than health-based limits defined by the Environmental Protection Agency,” said the Hopkins press release. They noted that “median aerosol concentrations of nickel, chromium and manganese approached or exceeded safe limits.”

However, the authors had expressed the results of their study in terms of environmental exposure. That means they judged the quantities of toxic metals inhaled as though they were being breathed continuously for 24 hours or during an 8-hour workday, rather than calculating risk based on the vapers’ actual daily usage of their devices. Vapers puff their atomizers a few hundred times a day, but we breathe about 17,000 times a day.

Some people fear all chemicals and metals in any quantity. They seem to have a fundamental misunderstanding of toxic exposures.

Now a paper by Greek cardiologist and vaping researcher Konstantinos Farsalinos and University of Louisville professor of medicine Brad Rodu takes the data from the Hopkins paper and shows how it relates to real-life vaping exposures. Their study was published in the journal Inhalation Toxicology.
