E-cigarettes leak toxic metals, study finds – Medical News Today

Several recent studies have suggested that electronic cigarettes may not be as safe as we may think, and a new study now adds that these popular devices leak harmful metals — some of them highly toxic.
New research suggests that toxic metals leaking from e-cigarettes could endanger health.

Ever since their release on the global market, electronic cigarettes (e-cigarettes) have been hailed, generally, as a safer alternative to the regular ones.

These devices work by heating up a flavored liquid that sometimes — though not always — contains nicotine.

Instead of smoke, e-cigarettes release aerosols, or “vapors,” which is why users of e-cigarettes are often referred to as “vapers,” and the act of “smoking” using this device is dubbed “vaping.”

Despite the popular belief that e-cigarettes are better for our health than traditional ones, recent research has indicated that these devices could bring about fresh, and little understood, risks.

It has been suggested that people who use e-cigatattes could have a higher risk of cardiovascular problems and cancer, and a study published earlier this month found that a few certain e-cigarette flavors are particularly toxic.

Now, a team of scientists from the Johns Hopkins Bloomberg School of Public Health in Baltimore, MD, concludes that e-cigarette vapors could also be harmful. Senior study author Ana María Rule and team surmise that the danger may arise from the toxic content of e-cigarette heating coils.

“It’s important for the FDA [Food and Drug Administration], the e-cigarette companies, and vapers themselves to know that these heating coils, as currently made, seem to be leaking toxic metals — which then get into the aerosols that vapers inhale.”

Smoking E-Cigarettes Daily Doubles Risk of Heart Attacks | UC San … – UCSF News Services

Daily use of electronic cigarettes is associated with nearly a doubling of the odds of a heart attack, according to a new study led by UC San Francisco. This is the first evidence of a substantial, human health impact of the popular devices that were first introduced about a decade ago, indicating that e-cigarettes may be more dangerous than previously thought.

The new study of nearly 70,000 people found that heightened heart attack risk for e-cigarettes is on top of the effects of conventional cigarettes, which by themselves nearly triple the odds of heart attack risk when smoked daily. Together they lead to five times the non-smoking heart attack risk in those who use both conventional cigarettes and e-cigarettes every day. 

The research will be presented February 24 in Baltimore at the 2018 annual meeting of the Society for Research on Nicotine and Tobacco.

“The finding of increased heart attack risk for e-cigarette use, in addition to the risks of any smoking, is particularly troubling, because most people who use e-cigarettes continue to smoke cigarettes,” said senior author Stanton Glantz, PhD, who presented the work. Glantz is a UCSF professor of medicine and director of the UCSF Center for Tobacco Control Research and Education.

The health effects of e-cigarettes have been a contentious topic in the scientific community in recent years, but evidence is mounting that links them to direct health harms.

Last month, a report from the National Academies of Sciences, Engineering, and Medicine cited a range of health impacts of e-cigarette use, ranging from exposure to nicotine and other toxic substances to “substantial” evidence that e-cigarette use results in symptoms of dependence. The report observed that there wasn’t yet evidence of the risks of heart, cancer or respiratory disease in people who used e-cigarettes, but

How healthy vaping is compared with smoking – Business Insider – Business Insider

Eduardo Munoz/Reuters

A new study found that people who vape may be inhaling potentially dangerous levels of toxic metals like lead. But the study did not directly compare the levels with those of conventional cigarettes — which some research suggests are higher and more worrisome. Most research suggests vaping is a healthier alternative to smoking, especially for adults who want to quit. But those studies have also revealed some of its potential downsides.

Smoking kills. No other habit has been so strongly tied to death.

In addition to inhaling burned tobacco and tar, smokers breathe in toxic metals like cadmium and beryllium, as well as metallic elements like nickel and chromium — all of which accumulate naturally in the leaves of the tobacco plant.

It’s no surprise, then, that most of the available evidence suggests that vaping, which involves puffing on vaporized liquid nicotine instead of inhaling burned tobacco, is at least somewhat healthier.

Still, we don’t have a ton of research on how vaping affects the body and brain.

It’s been less than a decade since the first vape pen hit store shelves as a bulky device the size of a whiteboard marker. Since then, countless varieties of electronic cigarettes have become available, from slim black sticks with tips that light up like conventional cigarettes to chrome cartridges that allow the user to personalize things like the amount of nicotine in each hit and the length of a pull.

In 2015, a group of researchers from medical schools across the globe decided to find out just what was inside the vapors that e-cig users were inhaling.

Trapped deep in the aerosol particles that vapers breathe were some of the same toxic metals and metallic elements found in conventional cigarettes, including cadmium and nickel. They also found potentially unsafe levels

Potentially toxic chemicals were found in e-cigarette vaper – Fox News

A new study out of Johns Hopkins says there may be toxic levels of metals including lead that could be leaking from e-cigarettes.  (Reuters)

A new warning about vaping published in Environmental Health Perspectives says there may be toxic levels of metals, including lead, that could be leaking from the heating coils of e-cigarettes.

Researchers from Johns Hopkins School of Public Health found metal traces in the aerosols inhaled by users, known as vapers.

The team tested liquids in the refilling dispensers from 56 Baltimore area vapers and found potentially unsafe levels of arsenic, chromium, manganese, nickel and lead.

Test results also showed that aerosol metal concentrations were highest for e-cigarettes with more frequently changed coils. Study authors pointed out that chronic inhalation of these metals has been linked to lung, liver, immune, cardiovascular and brain damage, and even cancers.

“It’s important for the FDA, the e-cigarette companies and vaper [users] themselves to know that these heating coils, as currently made, seem to be leaking toxic metals — which then get into the aerosols that vapers inhale,” said study senior author Ana María Rule, assistant scientist in the Bloomberg School’s Department of Environmental Health and Engineering.

The Food and Drug Administration has the authority to regulate e-cigarettes, but has not issued any rulings on the matter so far.

More research is planned to determine possible health effects.
