Vaping is NOT worth the potential heart risk, researchers warn against nearly 40 deaths and 1900 diseases related to e-cigarettes in the U.S.
- E-cigarettes are marketed as "safer" than cigarettes  Cigarettes are the number one risk factor for preventing heart disease
- Mysterious device-related lung diseases have killed 39 in the US – but the long-term effects are not yet known
- then What has been done so far suggests that vaping damages the heart and blood vessels
- Although the authors of the study say that much more research is needed on the long-term effects, the short-term evidence shows that vaping "is not worth the risk" [1
Vaping can still cause heart disease, even though it has been touted as a healthy alternative to smoking, warns new
In addition to nicotine, studies show that ash contains particles, metals and flavors – all of which contribute to cardiovascular problems.
The United States has observed nearly 40 deaths related to the short-term use of electronic cigarettes, ie. and the immediate effects on the heart and blood vessels observed in a handful of completed studies suggest that they could cause long-term cardiovascular damage.
To put it simply, vaping is "just not worth the risk," says the lead author of a new study at Ohio State University, Nicholas Buchanan.

He and his team reviewed research done so far on the cardiovascular effects of e-cigarettes, and though they say that much more and bigger studies are desperately needed, early data shows that devices cannot be called "safe".
Vaping increased from about seven million users in 2011 to 41 million last year – with an estimated increase to over 55 million by 2021, according to the World Health Organization.
"Many people think these products are safe, but there are more and more reasons to worry about their effects on heart health," says senior author Lauren Wald, director of biomedical research at the University College of Nursing in Ohio.
Evidence suggests that fine particles of an electronic cigarette can enter the bloodstream and affect the heart, acting in a similar manner to air pollution.
Researchers suggest that this can lead to increased blood pressure and stiffness in arteries, inflammation and over time heart disease.
Professor Wald says: "We know that these problems are observed in these studies addressing the short-term effects of vaping, but that the studies are inconsistent and the impact of chronic e-cigarette use is a mystery.
"The potential harm to the heart over time is essentially unexplored."
He believes the study should pause vapers and emphasize the need to regulate e-cigarettes to force companies to tell their customers exactly what they inhale.
The study's lead author, Nicholas Buchanan, a research associate in Ohio, says, "Especially for someone who has never smoked, it's just not worth the risk and it seems pretty convincing that you can say they are not harmless.
"There is a huge variety of e-liquids and different devices out there, and manufacturers don't have to tell you what's in them.
" For example, recent reports of vaping-related illnesses and deaths are not yet limited to one substance or product.
"While the use of THC-containing products appears to be related to these cases, the Cent Disease Control and Prevention Program reports that diseases do not appear to be limited to these types of products. "
Cigarette smoking is the most preventable risk factor for cardiovascular disease and death, and because of the perceived safety of vaping, many smokers have switched to electronic cigarettes.
Mr Buchanan adds: “The most worrying is the number of children and teenagers who acquire the habit – who may have never started smoking conventional cigarettes.
"We have no idea what
