Cigarettes vapor tested positive for Lead and Arsenic in new study

A new study from the Johns Hopkins School of Public Health has found that a significant number of e-cigarette devices generate aerosols with potentially unsafe levels of lead, chromium, manganese and/or nickel.

What is vaping and how does it work?

Researchers tested the liquid by itself, the liquid inside the e-cigarette and the aerosol inhaled by users, which is produced when the liquid is heated by a metal coil inside the e-cigarette. A 2017 survey of 8th-, 10th- and 12th-grade students in public and private schools, sponsored by the National Institute on Drug Abuse, found that about one in six had used e-cigarettes in the previous 30 days. "The FDA should assess whether e-cigarettes help to reduce tobacco-related morbidity and mortality, and the impact of marketing of e-cigarettes on consumer perceptions and behavior", the ACS added in its statement.

The researchers note that the toxic metals found in aerosols were "often much higher than safe limits".

"[While] using e-cigarettes instead of conventional cigarettes may result in less exposure to cadmium", the researchers said, they do not protect users from "other hazardous metals found in tobacco". Well, the researchers are almost certain that it's the metal coil used to heat the liquid.

VAPERS could be inhaling harmful levels of toxic metals linked to brain and heart damage, experts have warned. The median lead concentration in the aerosols, for example, was about 15 μg/kg, or more than 25 times greater than the median level in the refill dispensers.

Almost half of the e-cigarettes were producing vapor with lead concentrations over the maximums considered safe by the Environmental Protection Agency (EPA).

'These were median levels only, ' says senior study author Dr Ana María Rule.

"Every person that came into our study brought in their own device", she said.

West Virginia has the second highest rate of regular smoking in the country, but it's unclear how the state ranks in e-cigarette use.

E-cigarette heating coils typically are made of nickel, chromium and a few other elements, making them the most obvious sources of metal contamination, although the source of the lead remains a mystery.

"We know there are many young vapers that have never smoked", Dr. Rule said.

They found minimal amounts in the liquid but much larger amounts were in the heating coils and then transferred to the vapour.

The study examined not only the liquid inside e-cigs but also the liquid inside the pen's chamber and the vapor itself.

So, the team began a new project studying the latest devices, called Mods, as well as the aerosol inhaled by smokers.
