Cigarette Vapor Filled With Dangerous Toxins Like Lead, Study Finds

"These studies have also found a large variance in exposure levels among the users tested, which indicates harm can be significantly reduced with the use of quality products", Chowdhery said.

Further research is planned to better understand the possible health impact of e-cigs.

Researchers tested 56 daily users' e-cigarettes and e-liquids for 15 common metals. A significant number of the devices generated aerosols with potentially unsafe levels of lead, chromium, manganese and nickel.

Chronic inhalation of these metals is linked to lung, liver, immune, cardiovascular and brain damage, and cancers.

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.

"[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".

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

A new study out of Johns Hopkins says there may be toxic levels of metals including lead that could be leaking from e-cigarettes. Nearly 50 percent of aerosol samples had lead concentrations higher than health-based limits defined by the Environmental Protection Agency. In addition, the concentrations of nickel, chromium and manganese found in almost half of the aerosol samples exceeded the limits.

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

Bad news, vapers. Your e-cigs might not be the healthier alternative to cigarettes you think they are. "We don't know yet whether metals are chemically leaching from the coil or vaporizing when it's heated", she added. The refill e-liquid also detected significant levels of arsenic.

"Several shortcomings were found in a similar study conducted by the same institute previous year, including overestimating normal levels of exposure, not factoring in exposure to metals from daily activities, small sample size of products tested", Samrat Chowdhery, Director, Assocation of Vapers India (AVI), said in a statement. Most importantly, the scientists showed that the metal contamination carried over to the aerosols produced by heating the e-liquids.

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.
